In the method for producing granular products based on inorganic powder according to the present invention, a resin solution is prepared by dissolving polystyrene resin in a solvent, and the resin content in the resin solution is 100%.
It is characterized by adding and mixing 100 to 800 parts by weight of inorganic powder to parts by weight, and then volatilizing the solvent to obtain granules in which a layer of polystyrene resin is adhered around the inorganic powder. .
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

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を無機質粉
体と均一に混合する。混合する無機質粉体は炭酸
カルシウム、タルク、水酸化アルミニウム、マイ

てもよい。 Next, the above polystyrene resin solution is uniformly mixed with inorganic powder. Any inorganic powder to be mixed may be used, such as calcium carbonate, talc, aluminum hydroxide, mica, carbon black, etc.
無機質粉体の混合量を、ポリスチレン樹脂溶液

重量部としたのは、100重量部よりも少ないと無
機質の性質が薄くなり、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 amount of inorganic powder mixed is 100 to 800 parts by weight per 100 parts by weight of the resin contained in the polystyrene resin solution.
The reason for the weight part is that if it is less than 100 parts by weight, the inorganic properties will become thin, and if it is more than 800 parts by weight, the moldability of the obtained granules will decrease and the strength will be weak when formed into a molded product. Because it will be.

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 inorganic powder and the polystyrene solution as described above, the solvent is removed from the mixture by an appropriate 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 way, smooth granules without stickiness can be obtained. This granular material is easy to handle because it has a structure in which the core is an inorganic powder mixed in a resin solution, and a layer of polystyrene resin is attached to the outside.

填剤として使用することも可能である。 The biggest feature of the above granules obtained by the present invention is that
With the above structure in which the outer periphery of inorganic powder 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 inorganic powder is the main component. Therefore, the inorganic granules obtained by the present invention are suitable for producing various industrial material products such as building materials such as wall materials, floor materials, and attic materials, as well as electrical insulation boards such as lining materials for electrical control panels. ing. These inorganic granules are molded by heating, pressurizing and compressing them with a layer of polystyrene resin attached around them, thereby making them into molded bodies and contributing to their use. However,
When the inorganic granules are molded, the surrounding polystyrene resin melts and this resin acts as a binder, so they can be attached to any location as a building material without using any special adhesive. Furthermore, the inorganic granules themselves can be used, for example, as a filler when making cement.
