本発明はゴム細片およびポリスチレン樹脂から
両者の性質を併せもつた粒状の複合材料を製造す

For example, when a retreaded tire is manufactured by scraping off the worn tread surface layer of a used tire with a buffing machine or the like, then wrapping it with a rubber sheet and vulcanizing it, a large amount of rubber particles are produced as a secondary product. Conventionally, the scraped rubber pieces are disposed of and incinerated.

用する方法が望まれている。 In addition, in the case of vulcanized rubber products other than tires, most of the products that are no longer usable due to aging etc. are simply discarded, and these vulcanized rubber wastes are reused from the perspective of effective resource use and reduction of incineration costs. A method is desired.
上記の事情に鑑み、本発明はゴム細片およびポ

なされたものである。
In view of the above circumstances, the present invention provides a method for producing a granular composite material consisting of rubber pieces and polystyrene resin, and mainly composed of rubber pieces,
This was done with the aim of reusing vulcanized rubber waste.
本発明によるゴム細片を主体とした粒状物の製
造方法は、ポリスチレン樹脂を溶媒中に溶解して
樹脂溶液を調製し、該樹脂溶液中の樹脂分100重

The method for producing granular products mainly composed of rubber pieces according to the present invention involves dissolving polystyrene resin in a solvent to prepare a resin solution, and adding 100 to 100 parts of rubber pieces to 100 parts by weight of resin in the resin solution. After adding and mixing 800 parts by weight, the solvent is evaporated to obtain granules in which a layer of polystyrene resin is adhered around rubber pieces.
以下に本発明の詳細を説明する。 The details of the present invention will be explained below.
本発明では先ずポリスチレン溶液を調製する
が、その際の溶媒としては、ポリスチレンを溶解
し得るものであればどのようなものを用いてもよ
い。但し、このとき用いた溶媒は後で除去しなけ
ればならないから、例えばメチレンクロライドの
ような低沸点で且つ不燃性の有機溶媒を用いるの
が望ましい。また、上記の溶媒中に溶解するポリ
スチレン樹脂としては、ポリスチロールの粉体ま
たはペレツトの外、発泡スチロール製品、スチレ
ン樹脂成形物等の廃棄物を用いることができる。 In the present invention, a polystyrene solution is first prepared, and any solvent may be used as long as it can dissolve polystyrene. However, since the solvent used at this time must be removed later, it is desirable to use a nonflammable organic solvent with a low boiling point, such as methylene chloride. Further, as the polystyrene resin to be dissolved in the above-mentioned solvent, in addition to polystyrene powder or pellets, waste materials such as expanded polystyrene products and styrene resin moldings can be used.
なお、この樹脂溶液の濃度については特に限定
されるものではないが、粘度等の関係から溶媒
100重量部に対して樹脂分10〜70重量部程度とす
るのが作業性の点で望ましい。 Note that the concentration of this resin solution is not particularly limited, but due to the viscosity etc.
From the viewpoint of workability, it is desirable that the resin content be about 10 to 70 parts by weight per 100 parts by weight.
次に、上記のポリスチレン樹脂溶液とゴム細片
とを均一に混合する。混合するゴム粉体の形状は
不定形でよいが、大きさは10mm以下のものが好ま
しく、小さい方がよい。 Next, the polystyrene resin solution and rubber strips are uniformly mixed. The shape of the rubber powder to be mixed may be irregular, but the size is preferably 10 mm or less, and the smaller the better.
ゴム細片の混合量を、ポリスチレン樹脂溶液中
に含まれる樹脂分100重量部に対して100〜800重
量部としたのは、100重量部よりも少ないとゴム
の性質が薄くなり、また800重量部よりも多くな
ると得られた粒状物の成型性が低下して成形体と
したときの強度が弱くなるからである。 The reason why the mixed amount of rubber pieces was set to 100 to 800 parts by weight per 100 parts by weight of the resin contained in the polystyrene resin solution is because if it is less than 100 parts by weight, the properties of the rubber will become thin, and if the amount is less than 100 parts by weight, This is because if the amount exceeds 50%, the moldability of the resulting granules decreases and the strength when formed into a molded product becomes weak.
上記のようにゴム細片とポリスチレン溶液とを
混合した後、この混合物から適当な方法で溶媒を
除去する。脱溶媒の方法としてはニーダ、ミキサ

去することにより、ベトツキのないサラサラした

合したゴム細片を中核とし、その外側にポリスチ
レン樹脂の層が付着形成された構造を有している
ため取扱いが容易である。 After mixing the rubber strips and the polystyrene solution as described above, the solvent is removed from the mixture by any suitable method. As a method for removing the solvent, a method of stirring with a kneader, mixer, etc. to evaporate the solvent may be used. At this time, if the volatilized solvent is recovered by a solvent recovery device, it is economical and environmental pollution can be prevented. By removing the solvent in this manner, smooth granules without stickiness can be obtained. This granular material is easy to handle because it has a structure in which the core is a piece of rubber mixed in a resin solution, and a layer of polystyrene resin is attached to the outside of the core.
本発明で得られる上記粒状物の最大の特徴は、
ゴム細片の外周をポリスチレン樹脂層で被覆した
前記の構造により、ゴム細片を主体とするにもか
かわらず通常のポリスチレン樹脂と同様の成形法
により種々の無機質成形品を製造できることであ
る。従つて、本発明により得られるゴム細片粒状
物は建材や電気絶縁板等、種々の産業資材製品を
得るのに適している。 The greatest feature of the above granular material obtained by the present invention is that
Due to the above-mentioned structure in which the outer periphery of the rubber strip is covered with a polystyrene resin layer, various inorganic molded products can be manufactured using the same molding method as ordinary polystyrene resin, even though the rubber strip is the main component. Therefore, the rubber strip granules obtained by the present invention are suitable for obtaining various industrial material products such as building materials and electrical insulation boards.
