Description

【0001】
【発明の属する技術分野】
本発明は建築用板材に関するものである。
【0002】
【従来の技術】
一般に、建築用板材は、セメント、けい酸カルシウム源または石膏を主原料として製造されている。これらは板材としての強度を有するが、施工時のビスや釘打ち等で割れたり、裏面に剥離が生じたりする欠点がある。こうした欠点を防止するために、有機バインダを添加することが知られているが、その添加がシックハウス症候群などの原因となり健康によくない。
一方、消石灰やドロマイドプラスタを用いて炭酸ガスと反応させたものは、強度が低く板材としては不適である。
【0003】
【発明が解決しようとする課題】
本発明は、軽量かつ高強度で、切断、釘打ち性等の加工性に富んだ建築用板材の提供を目的とする。
【0004】
本発明は、700℃〜1,200℃で仮焼した少なくとも二酸化珪素と酸化カルシウムを含有する粉体を主成分とし、この主成分を含む原料を板状に成形し、炭酸ガスと反応させてなり、前記原料が、45〜98重量%の主成分である粉体と、2〜15重量%の有機繊維または無機繊維と、0〜40重量%の無機質充填材とを含んでなり、前記粉体が、少なくとも10〜20重量%の二酸化珪素と、40〜70重量%の酸化カルシウムとを含んでなることを特徴とする板材によって達成される。
【0005】
記粉体、天然原料または産業廃棄物もしくはその両方であることが好ましい。
前記粉体は、特定の粒度に予め粉砕されていることが好ましい。
【0006】
【発明の実施の態様】
以下、本発明を好ましい実施態様で詳述するが、本発明の内容はこれらの実施態様には限られない。
この実施態様において、まず、少なくとも二酸化珪素と酸化カルシウムを含有する天然原料または産業廃棄物もしくはその両方を粉砕して、700℃〜1,200℃で仮焼してなる粉体を主成分として製造する。
【0007】
次いで、板材を成形するが、その方法は特に限定されるものではないが、たとえば、45〜98重量%のかかる主成分に、2〜15重量%の有機繊維または無機繊維と0〜40重量%の無機質充填材とからなる配合物に水を加えてスラリー状態あるいは粘土状態にし、それらを型枠に打設してあるいは脱水プレス成形して所望の表面形状を得たり、またはスラリーを抄造してグリーンシートを得たり、あるいはグリーンシートに面プレスを行ったりして図1に示す板材状に成形する。その以外の方法としては押出成形法もある。
最後に、大気中あるいは炭酸ガス雰囲気中において、得られた成形体を養生して板材とする。養生は、大気養生のほか、蒸気養生、オートクレーブ養生など、各種の方法を採用することができる。
【0008】
本発明の仮焼温度は、700℃〜1,200℃であることが好ましく、700℃未満では粉体の活性が低く、成形養生後の板材には十分な強度が得られない。1,200℃より高いと粉体が焼結して固まり、活性が低下して使用できない。
また、本発明の粉砕工程では、主成分である粉体の粉末度(ブレーン値)を3,000〜10,000cm2/gにすることが好ましい。本発明で使用する天然原料または産業廃棄物もしくはその両方が仮焼前にすでに上記粉末値をもっていれば、粉砕工程は本態様においては必要としない。
【0009】
本発明において用いる仮焼する天然原料としては、10〜20重量%の二酸化珪素と40〜70重量%の酸化カルシウムを含む範囲であれば、特に限定するものではなく、たとえば、粘土鉱物、砂と石灰石等を混合して用いることができる。ここで使用する仮焼した粉体は、上記個々の原料をそれぞれ仮焼した後に混合されたものでも良い。
また、仮焼する産業廃棄物も、10〜20重量%の二酸化珪素と40〜70重量%の酸化カルシウムを含有する範囲であれば、特に限定するものではなく、たとえば、コンクリート廃材、建築廃材と下水処理場の汚泥等を使用できる。
また、上記天然原料と産業廃棄物との混合物として使用する場合でも、全体として10〜20重量%の二酸化珪素と40〜70重量%の酸化カルシウムを含めば、本発明に用いることができる。
【0010】
本発明の板材の原料は、主成分として45重量%〜98重量%の前記の仮焼した粉体を含むことが好ましく、45重量%未満では養生後の板材に十分な曲げ強度が得られなく、98重量%を超えた場合では、板材が硬く脆いため釘打ち性や加工性において実用的ではない。
【0011】
他に、2重量%〜15重量%の有機繊維または無機繊維の繊維成分を含むことができる。繊維成分が2重量%未満では、板が脆いため釘打ち性や加工性が実用的ではなく、15重量%を超えた場合では、釘打ち性や加工性は良好であるが、板の曲げ強度が低く実用的でない。
また、有機繊維としては、パルプ、ポリプロピレン、レーヨン、ビニロンと各種天然繊維等を、無機繊維としては、アスベスト、ロックウール、スラグウール、ガラス繊維とセラミック繊維等を用いることができる。
【0012】
さらに、0重量%〜40重量%の無機質充填材を含むことができる。その含有量が40重量%を超えた場合、板材の釘打ち性や加工性は良好であるが、板の曲げ強度が低く実用的でない。
また、無機質充填材としては、珪藻土、パーライト、バーミキュライト、けい酸カルシウムと石膏等を用いることができる。
【0013】
本発明では、板状に成形した後に強度を発現させて建築用板材とするためには、主成分に含まれている酸化カルシウムを炭酸ガスと反応させて炭酸カルシウムを生じさせる必要がある。本態様では、成形した後に炭酸ガス雰囲気中において、成形体を養生することが好ましい。

1 板材[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a building plate.
[0002]
[Prior art]
In general, a building board is manufactured using cement, a calcium silicate source or gypsum as a main raw material. These have strengths as plate materials, but have the disadvantage that they are broken by screws or nailing during construction, or the back surface is peeled off. In order to prevent such drawbacks, it is known to add an organic binder, but this addition causes sick house syndrome and is not good for health.
On the other hand, what made it react with a carbon dioxide gas using slaked lime or a dolomide plaster has low intensity | strength, and is unsuitable as a board | plate material.
[0003]
[Problems to be solved by the invention]
An object of this invention is to provide the board | plate material for building which is lightweight and high intensity | strength, and was rich in workability | operativity, such as cutting and nailing.
[0004]
The present invention mainly comprises a powder containing at least silicon dioxide and calcium oxide calcined at 700 ° C. to 1,200 ° C., and a raw material containing this main component is formed into a plate shape and reacted with carbon dioxide gas. becomes the raw material, a powder which is a main component of 45 to 98 wt%, and 2 to 15 wt% of organic or inorganic fibers, Ri name and a 0-40% by weight of inorganic filler, wherein powder is achieved by the plate member, wherein at least 10 to 20 wt% of silicon dioxide, a Rukoto Do and a calcium oxide 40 to 70 wt%.
[0005]
Before Kikotai is preferably a natural or industrial waste or both.
The powder is preferably pulverized in advance to a specific particle size.
[0006]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, although the present invention is explained in full detail in a preferred embodiment, the contents of the present invention are not limited to these embodiments.
In this embodiment, first, a natural raw material containing at least silicon dioxide and calcium oxide and / or industrial waste is pulverized and calcined at 700 ° C. to 1,200 ° C. to produce a powder as a main component.
[0007]
Next, the plate material is formed, but the method is not particularly limited. For example, the main component is 45 to 98% by weight, the organic fiber or inorganic fiber is 2 to 15% by weight, and 0 to 40% by weight. Water is added to the composition comprising the inorganic filler to form a slurry state or clay state, which is cast into a mold or dehydrated and pressed to obtain a desired surface shape, or the slurry is made. A green sheet is obtained or a surface press is performed on the green sheet to form the plate material shown in FIG. Another method is an extrusion method.
Finally, the obtained molded body is cured into a plate material in the air or in a carbon dioxide atmosphere. In addition to air curing, various methods such as steam curing and autoclave curing can be used for curing.
[0008]
The calcining temperature of the present invention is preferably 700 ° C. to 1,200 ° C. If it is less than 700 ° C., the activity of the powder is low, and sufficient strength cannot be obtained for the plate material after molding and curing. If it is higher than 1,200 ° C, the powder will sinter and solidify, and its activity will decrease and it cannot be used.
In the pulverization step of the present invention, the fineness (brain value) of the powder as the main component is preferably 3,000 to 10,000 cm 2 / g. If the natural raw materials and / or industrial waste used in the present invention already have the above powder value before calcination, the pulverization step is not necessary in this embodiment.
[0009]
The natural raw material to be calcined used in the present invention is not particularly limited as long as it contains 10 to 20% by weight of silicon dioxide and 40 to 70% by weight of calcium oxide. For example, clay minerals, sand and the like Limestone or the like can be mixed and used. The calcined powder used here may be a mixture obtained by calcining the individual raw materials.
Moreover, the industrial waste to be calcined is not particularly limited as long as it contains 10 to 20% by weight of silicon dioxide and 40 to 70% by weight of calcium oxide. For example, concrete waste and building waste Sludge from sewage treatment plants can be used.
Even when used as a mixture of the above-mentioned natural raw material and industrial waste, it can be used in the present invention as long as it contains 10 to 20% by weight of silicon dioxide and 40 to 70% by weight of calcium oxide as a whole.
[0010]
The raw material of the plate material of the present invention preferably contains 45% to 98% by weight of the calcined powder as a main component, and if it is less than 45% by weight, sufficient bending strength cannot be obtained for the plate material after curing. When the content exceeds 98% by weight, the plate material is hard and brittle, so that it is not practical in nailing and workability.
[0011]
In addition, the fiber component of 2 to 15% by weight of organic fiber or inorganic fiber can be included. If the fiber component is less than 2% by weight, the plate is brittle, so the nailability and workability are not practical. If it exceeds 15% by weight, the nailability and workability are good, but the bending strength of the plate Is not practical.
Further, as the organic fiber, pulp, polypropylene, rayon, vinylon and various natural fibers can be used, and as the inorganic fiber, asbestos, rock wool, slag wool, glass fiber and ceramic fiber can be used.
[0012]
Furthermore, 0 to 40% by weight of an inorganic filler can be included. When the content exceeds 40% by weight, the nailability and workability of the plate material are good, but the bending strength of the plate is low and not practical.
Moreover, as an inorganic filler, diatomaceous earth, perlite, vermiculite, calcium silicate, gypsum, etc. can be used.
[0013]
In the present invention, it is necessary to react calcium oxide contained in the main component with carbon dioxide gas to produce calcium carbonate in order to develop strength after forming into a plate shape to obtain a building board material. In this embodiment, it is preferable to cure the molded body in a carbon dioxide atmosphere after molding.
[0014]
