Description
本発明は、コケが樹脂表面に育成することができるコケ育成樹脂に関する。 The present invention relates to a moss-growing resin that allows moss to grow on the resin surface.
コケが育成することにより、様々な良い点がある。一例として、独特の外観や自然の美しさをもたらしたり、湿度を保てたり、昆虫や小さな生物の生息地なったり、二酸化炭素を吸収して空気の質を改善したり、風や雨から土壌を保護したり、庭園やランドスケープデザインの一部として活用されたりする。従来、コケを育成させるには、コケを育成させたい場所にシートやネットを敷いてコケを育成させていた。シートやネットが天然繊維等ではなく、樹脂を原料としていた場合、樹脂の表面にコケが生えることはなかったし、コケを育成させるためのシートやネットは、自然界で分解されなかった。 There are many benefits to growing moss. For example, it brings a unique appearance and natural beauty, helps maintain humidity, provides a habitat for insects and small creatures, improves air quality by absorbing carbon dioxide, protects the soil from wind and rain, and is used as part of garden and landscape design. Traditionally, moss was grown by laying sheets or nets in the area where it was desired to grow. If the sheets or nets were made from resin rather than natural fibers, moss would not grow on the surface of the resin, and the sheets and nets used to grow moss would not decompose in nature.
先行文献１は、細骨材と樹脂バインダーとを含み表面に凹部を有するコケ育成用硬化体を開示しているが、多孔質の凹部が土や水分を保持し、そこにコケが育成すものであるから、細骨材や樹脂バインダーにコケは生育しないし、コケ育成用硬化体に含まれる樹脂は自然界では分解されず、そのままの形状で残存する。 Prior art document 1 discloses a hardened material for cultivating moss that contains fine aggregate and a resin binder and has recesses on its surface. However, the porous recesses hold soil and moisture, and moss grows in them. Therefore, moss does not grow on the fine aggregate or resin binder, and the resin contained in the hardened material for cultivating moss does not decompose in nature and remains in its original form.
本発明は、樹脂の表面にコケが育成し、長い時間が経過すれば崩壊するコケ育成樹脂を提供する。 The present invention provides a moss-growing resin that grows on the surface of the resin and disintegrates over a long period of time.
コケ育成樹脂は、平均粒径が５ｍｍ以下のおからと熱可塑性樹脂とを含むコケ育成樹脂であって、
前記おからの質量は、前記コケ育成樹脂の質量に対し１０％以上６０％以下である。
The moss cultivation resin is a moss cultivation resin containing soybean pulp having an average particle size of 5 mm or less and a thermoplastic resin,
The mass of the soybean pulp is 10% or more and 60% or less of the mass of the moss cultivation resin.
コケ育成樹脂の製造方法は、調整おから製造工程と、調整おからと熱可塑性樹脂を加熱混錬する混錬工程と、を含み、
前記調整おから製造工程は、原料おからの平均粒径を５ｍｍ以下にする粉砕工程と、原料おからを表面温度が２６０℃以下で乾燥して含水率が０．１％以上２０％以下にする乾燥工程と、を含む。
The method for producing the moss-growing resin includes a process for producing a regulated soybean pulp, and a process for heating and kneading the regulated soybean pulp and a thermoplastic resin.
The adjusted soybean pulverization process includes a grinding process for reducing the average particle size of the raw soybean pulverization material to 5 mm or less, and a drying process for drying the raw soybean pulverization material at a surface temperature of 260°C or less to reduce the moisture content to 0.1% or more and 20% or less.
前記コケ育成樹脂にコケを育成させるコケ育成方法は、コケ育成樹脂の少なくとも一部を、土壌に接触させ、
前記コケ育成樹脂又は前記コケ育成樹脂が接触している土壌に水を与えるものである。
The moss cultivation method for cultivating moss in the moss cultivation resin comprises contacting at least a portion of the moss cultivation resin with soil,
Water is applied to the moss cultivation resin or to the soil in contact with the moss cultivation resin.
前記コケ育成方法は、前記コケ育成樹脂又は前記コケ育成樹脂が接触している土壌にコケ又はコケの種子を植えても良い。 The moss cultivation method may involve planting moss or moss seeds in the moss cultivation resin or in soil in contact with the moss cultivation resin.
前記コケ育成樹脂を用いた樹脂製品は、樹脂製品の表面にコケを育成させて経時変化を観察できる。 When using the moss-growing resin in a resin product, moss can be grown on the surface of the resin product, allowing the changes over time to be observed.
前記コケ育成樹脂を用いた模型は、模型の表面にコケを育成させて経時変化を観察できる。 When using the moss-growing resin, models can be grown with moss on the surface of the model, allowing the changes over time to be observed.
本発明のコケ育成樹脂は、コケ育成樹脂の表面でコケを育成することができる。表面に育成したコケは、コケ育成樹脂に含まれるおからを分解するため、コケ育成樹脂は長い時間が経過すれば崩壊し、環境への負荷が少ない。 The moss-growing resin of the present invention allows moss to grow on its surface. The moss grown on the surface decomposes the soybean pulp contained in the moss-growing resin, so the moss-growing resin will break down over time, resulting in less environmental impact.
以下、本発明の実施の形態の例について図を参照しながら説明する。尚、本発明は、以下の形態の例に限定されるものではない。 Below, examples of embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the following examples of embodiments.
本発明のコケ育成樹脂は、平均粒径が５ｍｍ以下でｐＨが４．０以上８．０以下のおからと熱可塑性樹脂とを含む。前記おからの質量は、前記コケ育成樹脂の質量に対し１０％以上６０％以下である。前記熱可塑性樹脂は、特に限定はなく、一例として、生分解性樹脂、ポリエチレン、ポリプロピレン、ポリ塩化ビニル、ポリスチレンのうち少なくとも一つである。 The moss cultivation resin of the present invention includes soybean pulp having an average particle size of 5 mm or less and a pH of 4.0 to 8.0, and a thermoplastic resin. The mass of the soybean pulp is 10% to 60% of the mass of the moss cultivation resin. The thermoplastic resin is not particularly limited, and is, for example, at least one of biodegradable resin, polyethylene, polypropylene, polyvinyl chloride, and polystyrene.
おからの種類は、特に限定はなく、一例として、食品製造会社等が豆腐などの食品を製造する際に産出されるバイオマスとする。前記コケ育成樹脂に含まれるおからは、平均粒径が５ｍｍ以下とする。おからの平均粒径が５ｍｍを超えると、コケ育成樹脂からおからが脱落するおそれがある。コケ育成樹脂に含まれるおからの質量は、コケ育成樹脂の質量に対し１０％以上６０％以下とし、好ましくは、１０％以上４０％以下とする。おからの質量が１０％に満たない場合、コケ育成樹脂の表面にコケが育成しにくくなり、おからの質量が６０％を超える場合、コケ育成樹脂の強度が低下し、樹脂製品等の原料として使用することが困難となる。一例として前記コケ育成樹脂に含まれるおからのｐＨは４．０以上６．５以下とする。コケはおからを栄養として育成するため、ｐＨが前記範囲から外れると、コケを育成しにくくなるからである。 The type of soybean pulp is not particularly limited, and as an example, it is biomass produced when food manufacturers manufacture foods such as tofu. The soybean pulp contained in the moss cultivation resin has an average particle size of 5 mm or less. If the average particle size of the soybean pulp exceeds 5 mm, the soybean pulp may fall off from the moss cultivation resin. The mass of the soybean pulp contained in the moss cultivation resin is 10% to 60% of the mass of the moss cultivation resin, and preferably 10% to 40%. If the mass of the soybean pulp is less than 10%, it becomes difficult for moss to grow on the surface of the moss cultivation resin, and if the mass of the soybean pulp exceeds 60%, the strength of the moss cultivation resin decreases, making it difficult to use it as a raw material for resin products, etc. As an example, the pH of the soybean pulp contained in the moss cultivation resin is 4.0 to 6.5. This is because moss grows using soybean pulp as nutrients, and if the pH is outside the above range, it becomes difficult for moss to grow.
本発明のコケ育成樹脂は、本発明の効果を阻害しない範囲でその他の原料を添加することができる。その他の原料は、例えば、可塑剤、安定剤、酸化防止剤、紫外線吸収剤、滑材、剥離剤、帯電防止剤、充てん剤、着色剤、発泡材、難燃剤、セルロースナノファイバー等から１種又は２種以上を選択し添加する。 Other raw materials can be added to the moss-growing resin of the present invention as long as they do not impair the effects of the present invention. The other raw materials can be selected from, for example, one or more of plasticizers, stabilizers, antioxidants, UV absorbers, lubricants, release agents, antistatic agents, fillers, colorants, foaming agents, flame retardants, cellulose nanofibers, etc.
次に、コケ育成樹脂の製造方法について説明する。 Next, we will explain the manufacturing method of moss cultivation resin.
本発明のコケ育成樹脂の製造方法は、調整おから製造工程と、調整おからと熱可塑性樹脂を加熱混錬する混錬工程と、を含む。前記調整おから製造工程は、コケ育成樹脂の原料となる原料おからの平均粒径を５ｍｍ以下にする粉砕工程と、コケ育成樹脂の原料となる原料おからを表面温度が２６０℃以下で乾燥して含水率が０．１％以上２０％以下にする乾燥工程と、を含む。 The method for producing moss-growing resin of the present invention includes a regulated okara production process and a kneading process in which the regulated okara and thermoplastic resin are heated and kneaded. The regulated okara production process includes a crushing process in which the average particle size of the raw okara, which is the raw material for the moss-growing resin, is reduced to 5 mm or less, and a drying process in which the raw okara, which is the raw material for the moss-growing resin, is dried at a surface temperature of 260°C or less to reduce the moisture content to 0.1% or more and 20% or less.
前記調整おから製造工程は、原料おからを熱可塑性樹脂と混錬しやすくし、コケ育成樹脂に適する状態に調整する工程であり、粉砕工程と乾燥工程とを含む。前記原料おからは、食品製造会社等が豆腐などの食品を製造する際に産出されるバイオマスであり、人が食するために加工されたおからを用いなくてもよい。 The adjusted okara manufacturing process is a process for making the raw okara easier to mix with thermoplastic resin and adjusting it to a state suitable for moss cultivation resin, and includes a crushing process and a drying process. The raw okara is biomass produced when food manufacturers manufacture foods such as tofu, and it is not necessary to use okara that has been processed for human consumption.
前記粉砕工程は、原料おからの平均粒径を５ｍｍ以下に粉砕する工程である。バイオマスとして産出されるおからは、大豆の皮などが混入している場合があるため、熱可塑性樹脂との加熱混合に適するように平均粒径を５ｍｍ以下にする。例えば、調整おからに粒径が１０ｍｍを超えるなど粒径が大きいものが混入している場合、コケ育成樹脂を製造した場合に、粒径が大きいものが樹脂から脱落してしまうリスクがある。粉砕方法は、特に限定はなく、一般的な方法を用いれば良く、一例として、粉砕後に篩でふるうなどして所望の粒径以下にする。 The grinding process is a process in which the raw okara is ground to an average particle size of 5 mm or less. Okara produced as biomass may contain soybean husks and the like, so the average particle size is set to 5 mm or less to make it suitable for heating and mixing with thermoplastic resin. For example, if the adjusted okara contains particles with a large particle size, such as particles with a particle size of over 10 mm, there is a risk that the large particles will fall off when moss cultivation resin is produced. There are no particular limitations on the grinding method, and any general method may be used. As an example, after grinding, the particles are sieved to a desired particle size or less.
前記乾燥工程は、原料おからを乾燥する工程である。バイオマスとして産出されるおからは水分を多く含む場合があるため、熱可塑性樹脂との加熱混合に適するように含水率が０．１％以上２０％以下にする。乾燥方法は、特に限定はなく、一般的な方法を用いれば良く、一例として、熱風乾燥法を用いることができる。乾燥の際には、原料おからの表面温度が２６０℃以下になるようにする。原料おからの表面温度が２６０℃を超えた状態で乾燥すると、原料おからが焦げる等して成分が変性するため、コケ育成樹脂を製造した場合、コケを育成しにくくなるリスクがある。熱風の温度の下限は特に限定はなく、一例として約８０℃とする。前記粉砕工程後に前記乾燥工程を行うことにより、乾燥効率を上げることができる。 The drying process is a process for drying the raw okara. Since the okara produced as biomass may contain a large amount of moisture, the moisture content is set to 0.1% to 20% so that it is suitable for heating and mixing with the thermoplastic resin. There is no particular limitation on the drying method, and any common method may be used. For example, hot air drying can be used. When drying, the surface temperature of the raw okara is set to 260°C or lower. If the raw okara is dried when its surface temperature exceeds 260°C, the raw okara will burn and its components will denature, and there is a risk that it will be difficult to grow moss if a moss-growing resin is produced. There is no particular limitation on the lower limit of the hot air temperature, and for example, it is set to about 80°C. By performing the drying process after the crushing process, the drying efficiency can be increased.
調整おから製造工程は、一例として、原料おからのｐＨを４．０以上６．５以下にするｐＨ調整工程を含んでも良い。前記ｐＨ調整工程は、原料おからのｐＨを４．０以上６．５以下にする工程である。バイオマスとして産出されるおからは、酸化によりｐＨが低くなりすぎたり、アルカリ性物質の混入等によりｐＨが高くなりすぎたりする場合がある。原料おからがｐＨ４．０に満たない状態でコケ育成樹脂に使用した場合、コケは育成しにくくなるリスクがある。また、ｐＨが６．５を超える状態でコケ育成樹脂に使用した場合もコケは育成しにくくなる。ｐＨを調整する方法は、特に限定はなく、一般的な方法を用いれば良く、一例として、クエン酸、リンゴ酢等の酸を添加したり、重曹、アンモニア等のアルカリを添加するなどの方法を用いることができる。 The adjusted okara manufacturing process may include, for example, a pH adjustment process for adjusting the pH of the raw okara to 4.0 or more and 6.5 or less. The pH adjustment process is a process for adjusting the pH of the raw okara to 4.0 or more and 6.5 or less. The pH of the okara produced as biomass may become too low due to oxidation, or may become too high due to the inclusion of alkaline substances. If raw okara is used in a moss cultivation resin when its pH is less than 4.0, there is a risk that moss will not grow easily. In addition, if the raw okara is used in a moss cultivation resin when its pH is more than 6.5, moss will not grow easily. There are no particular limitations on the method for adjusting the pH, and any general method may be used. For example, an acid such as citric acid or apple vinegar may be added, or an alkali such as baking soda or ammonia may be added.
可塑剤、安定剤、酸化防止剤、紫外線吸収剤、滑材、剥離剤、帯電防止剤、充てん剤、着色剤、発泡材、難燃剤等のその他の原料を加える場合は、一例として、調整おからと熱可塑性樹脂を混錬する際に併せて混錬する。全ての原料を、混錬押出機に一度に投入して混錬することができるため、製造効率を向上させることができる。 When adding other raw materials such as plasticizers, stabilizers, antioxidants, UV absorbers, lubricants, release agents, antistatic agents, fillers, colorants, foaming agents, and flame retardants, for example, they are kneaded together when kneading the adjusted soybean pulp and thermoplastic resin. All raw materials can be fed into the kneading extruder at once and kneaded, improving production efficiency.
前記混錬工程は、調整おからと熱可塑性樹脂を加熱・混錬する工程である。調整おからは、コケ育成樹脂の質量に対し１０％以上６０％以下になるように、熱可塑性樹脂と混合して、加熱混錬する。加熱混錬の方法は、一般的な機械や方法を用いれば良く、一例としてヘンシェルミキサー、バンバリーミキサー、単軸スクリュー押出機、多軸スクリュー押出機、コニーダ等を用いる。加熱・混錬の条件は、一般的な条件を用いれば良く、熱可塑性樹脂に適した温度や、回転数を用いる。 The kneading process is a process of heating and kneading the adjusted soybean pulp and the thermoplastic resin. The adjusted soybean pulp is mixed with the thermoplastic resin so that the amount of the adjusted soybean pulp is 10% to 60% of the mass of the moss cultivation resin, and then heated and kneaded. The method of heating and kneading can be performed using general machines and methods, and examples of the method include a Henschel mixer, a Banbury mixer, a single-screw extruder, a multi-screw extruder, and a co-kneader. The conditions of heating and kneading can be general conditions, and the temperature and rotation speed suitable for the thermoplastic resin are used.
次に、本発明のコケ育成樹脂を用いたコケ育成方法について説明する。 Next, we will explain the moss cultivation method using the moss cultivation resin of the present invention.
本発明のコケ育成樹脂の少なくとも一部を、土壌に接触させ、前記コケ育成樹脂又は前記コケ育成樹脂が接触している土壌に水を与えることにより、前記コケ育成樹脂上にコケを育成させる。 At least a portion of the moss cultivation resin of the present invention is brought into contact with soil, and moss is grown on the moss cultivation resin by providing water to the moss cultivation resin or to the soil in contact with the moss cultivation resin.
前記コケ育成樹脂と接触する土壌は、特に限定はなくコケが育成できる土壌であればよい。一例として、コケが生えている近辺の土壌、植物栽培用の土壌などを用いる。 The soil that comes into contact with the moss-growing resin is not particularly limited, and may be any soil in which moss can grow. As an example, soil near where moss grows, soil for plant cultivation, etc. may be used.
一例として、前記コケ育成樹脂又は前記コケ育成樹脂が接触している土壌にコケ又はコケの種子を植えることにより、コケの育成を促進させることができる。コケ又はコケの種子の植える方法は、特に限定はなく、コケ育成樹脂又は土壌の上にコケ又はコケの種子を載置する等の方法を用いる。 As an example, moss growth can be promoted by planting moss or moss seeds in the moss growth resin or in soil in contact with the moss growth resin. There are no particular limitations on the method for planting the moss or moss seeds, and methods such as placing the moss or moss seeds on the moss growth resin or soil can be used.
前記コケ育成樹脂又は前記コケ育成樹脂が接触している土壌に水を与える方法及び与える水の量は特に限定はなく、コケの生育に適する状態にすればよい。 There are no particular limitations on the method of watering the moss cultivation resin or the soil in contact with the moss cultivation resin, or the amount of water to be added, as long as the conditions are suitable for moss growth.
前記コケ育成樹脂の形状は、特に限定はなく、コケを育成したい場所に応じて所望の形状にする。一例として、ペレット状、板状、棒状、網状、筒状、箱状、又はブロック状などの内、少なくとも一種とする。 The shape of the moss cultivation resin is not particularly limited, and it can be made into a desired shape depending on the location where the moss is to be cultivated. As an example, it can be in at least one of the following shapes: pellet, plate, rod, net, cylinder, box, or block.
前記コケ育成樹脂を土壌に接触させる方法は、特に限定はなく、コケを育成したい場所によって応じて選択する。一例として、ペレット状の場合は、土壌の表面にまき、板状、棒状、網状の場合は、土壌の表面に載置することにより、土壌の表面及び土壌に載置したコケ育成樹脂の表面にコケを育成させることができる。自然の環境でコケが育成することにより、森林の地面や岩肌に豊かさをもたらし、自然の景観を補完する。 There are no particular limitations on the method of contacting the moss cultivation resin with the soil, and the method is selected depending on the location where moss is desired to be cultivated. As an example, in the case of pellets, they can be spread on the surface of the soil, while in the case of plates, rods, or nets, they can be placed on the surface of the soil, allowing moss to grow on the surface of the soil and on the surface of the moss cultivation resin placed on the soil. Moss growing in a natural environment brings richness to the forest floor and rock surfaces, complementing the natural landscape.
筒状の場合は、一例として、筒の中心線を略鉛直方向にして土壌に埋めこむことにより、コケ育成樹脂の土壌から突出した内周面及び外周面にコケを育成させることができる。 In the case of a cylindrical shape, for example, the center line of the cylinder can be oriented approximately vertically and buried in the soil, allowing moss to grow on the inner and outer circumferential surfaces of the moss-growing resin that protrude from the soil.
箱状の場合は、一例として、箱状体の内部に土壌を入れることにより、箱状体の外面にコケを育成させることができる。箱状体の一例として、植木鉢や植物育成用ポットとし、内部に土壌を入れ、植物を栽培する。植物に水を与えることにより、コケ育成用樹脂の植木鉢又は植物育成用ポットの外面にコケが育成し、特別な外観を有するものとなる（図３、４参照）。 In the case of a box-shaped body, for example, soil can be placed inside the box-shaped body to allow moss to grow on the outside of the box-shaped body. One example of a box-shaped body is a flowerpot or plant-growing pot, with soil placed inside and a plant grown inside. By watering the plant, moss grows on the outside of the flowerpot or plant-growing pot made of moss-growing resin, giving it a special appearance (see Figures 3 and 4).
ブロック状の場合、一例として、地面に載置したり、一部埋設したりすることにより、ブロック状体の外面にコケを育成することができる。ブロックの形状を所望の形状にすることにより、表面にコケが育成した様々な形状の立体物をつくることができる。 In the case of a block-shaped object, for example, it can be placed on the ground or partially buried, allowing moss to grow on the exterior surface of the block-shaped object. By forming the block into the desired shape, it is possible to create three-dimensional objects of various shapes with moss growing on the surface.
次に、本発明のコケ育成用樹脂を用いた樹脂製品について説明する。 Next, we will explain the resin products that use the moss cultivation resin of the present invention.
前記コケ育成樹脂を使用した樹脂製品は、表面にコケが育成できるので、樹脂製品の表面をコケが覆っていき、自然な特別な外観を有するとともに、コケが生育範囲が広がる経時変化を観察できる。 Moss can grow on the surface of resin products that use the moss-growing resin, so the moss will cover the surface of the resin product, giving it a natural and special appearance, and you can observe the changes over time as the moss' growth range expands.
コケ育成樹脂を用いた樹脂製品は、樹脂製品の表面がコケで覆われることを所望するものであれば、特に限定はない。一例として、石畳や庭園の石、木の装飾品、植木鉢、プランター、庭の彫刻、灯篭、ガーテンライト、屋根、壁、門、フェンス、バードパス、水槽、テラリウム、等がある。これらは、コケが育成することにより、特別な雰囲気を演出することができる。 There are no particular limitations on resin products that use moss-growing resin, so long as it is desired that the surface of the resin product be covered with moss. Examples include cobblestones and garden stones, wooden ornaments, flower pots, planters, garden sculptures, lanterns, garden lights, roofs, walls, gates, fences, bird paths, aquariums, terrariums, etc. These can create a special atmosphere by growing moss on them.
本発明のコケ育成樹脂は、模型の表面にコケが生育して経時変化観察できる樹脂製の模型として使用できる。前記模型は、特に限定はなく、コケが生育していることにより、独特の雰囲気を演出できる者であれば、特に限定はない。一例として、城や神舎仏閣などの建造物や、苔むしたものが登場するアニメや小説などの世界観をジオラマなどとして作ることができる。 The moss-growing resin of the present invention can be used as a resin model on which moss grows and changes over time can be observed. There are no particular limitations on the model, so long as it can produce a unique atmosphere by growing moss. As an example, it can be used to create a diorama that recreates the world of buildings such as castles and shrines and temples, or the world of anime and novels that feature moss-covered things.
本発明のコケ育成樹脂は、回収することが困難で自然界に放置される樹脂製品に利用できる。本発明のコケ育成樹脂の表面に育成するコケなどは、コケ育成樹脂に含まれるおからを分解するため、コケ育成樹脂は長い時間が経過すれば崩壊し、そのままの形状で残存しな。一例として、おもちゃの鉄砲の玉や、サバイバルゲームに用いるモデルガンなどの銃弾などが挙げられる。 The moss-growing resin of the present invention can be used for resin products that are difficult to recover and are left in the natural environment. Moss that grows on the surface of the moss-growing resin of the present invention decomposes the soybean pulp contained in the moss-growing resin, so the moss-growing resin will disintegrate over time and will not remain in its original shape. Examples include toy gun balls and bullets from model guns used in survival games.
次に実施例を挙げ、本発明を説明するが、本発明はこれらの実施例に何ら制約されるものではない。 The present invention will be described below with reference to examples, but the present invention is not limited to these examples.
本発明のコケ育成樹脂を用いた容器を作った。はじめにｐＨが５．５程度の原料おからの平均粒径を５ｍｍ以下にするため、微粉砕した。次に、２８０℃～３００℃程度の熱風を発生させ、微粉砕したおからの表面温度が約８０℃～１３０℃になるように加熱し、含水率を約８％乾燥させ、調整おからとした。前記調整おからとポリプロピレンとを、質量比３０：７０となるように混合した後、加熱・混錬押押出機を用いて、混錬し、ペレットとした後、カップ状の容器に成形した。成型後の容器の写真を図１に示す。 A container was made using the moss-growing resin of the present invention. First, the raw okara, which had a pH of about 5.5, was finely ground to an average particle size of 5 mm or less. Next, hot air at about 280°C to 300°C was generated, and the finely ground okara was heated so that the surface temperature reached about 80°C to 130°C, and dried to a moisture content of about 8%, to produce adjusted okara. The adjusted okara and polypropylene were mixed in a mass ratio of 30:70, and then kneaded and pelletized using a heating/kneading extruder, which was then molded into a cup-shaped container. A photograph of the container after molding is shown in Figure 1.
上記容器に、市販のシクラメンの苗を植えた。使用した土は、ホームセンターで購入した園芸用の土を用いた。その後、一般的なシクラメンの育て方のとおり、水を与えた。シクラメンを植えて約４月後の写真を図２に示す。 A commercially available cyclamen seedling was planted in the container. The soil used was gardening soil purchased from a home improvement store. After that, the seedling was watered as per the general method of growing cyclamen. Figure 2 shows a photograph of the cyclamen about four months after planting.
シクラメンを植えて約１６月経過したころから、容器に入った土壌の表面と容器の下の方にコケが育成しはじめた。シクラメンを植えて約１８月後の写真を図３に示す。 About 16 months after planting the cyclamen, moss began to grow on the surface of the soil in the container and at the bottom of the container. Figure 3 shows a photo of the cyclamen about 18 months after planting.
その後、水を与え続けたところ、コケの生育域は拡がり続けた。シクラメンを植えてから約３６月後の写真を図３に示す。 After that, the moss continued to grow as the water continued to be given to the plant. Figure 3 shows a photo of the cyclamen taken approximately 36 months after planting.
以上のとおり、本発明のコケ育成樹脂は、表面にコケを育成することができた。
As described above, the moss cultivation resin of the present invention was able to cultivate moss on its surface.
