Prior Art and Problems to be Solved by the Invention] When molding a polyamide resin, it is known that the strength of the molded product will be increased if an inorganic filler material is included. However, when a polyamide resin reinforced with an inorganic filler is processed into a molded product, flow marks and silver (white striped patterns), which indicate the irregular flow of the molding material, appear on the surface of the molded product. In addition, when secondary surface processing such as plating or painting is applied to these molded products, the adhesion between the surface treatment material and the molded product decreases, resulting in poor appearance of the processed surface. There was a problem that remained.

混合して使用することができる。Inorganic fillers used in the present invention include natural silicon compounds such as quartz, asbestos, diatomaceous earth, and mica, and metal salts such as calcium sulfate, calcium carbonate, calcium silicate (watestonite), magnesium carbonate, and silica-resistant magnesium (talc). , kaolin, clay and the like, and these inorganic fillers can be used alone or in combination of two or more.
無機充填材料の粒径は２０ｇ＋ｗ以下がよく、２０μｍ
より大きいと成形品の表面平滑性が低下し好ましくない
。The particle size of the inorganic filler material is preferably 20g+w or less, and is 20μm.
If it is larger, the surface smoothness of the molded product will deteriorate, which is not preferable.

面平滑性が低下し、ポリエチレンソルビタンの脂肪酸エ
ステルを添加する効果が十分に得られないからである。The content of the inorganic filler material is preferably 30 to 100 parts by weight per 100 parts by weight of the polyamide. The reason for this is that if the content is less than 30 parts by weight, sufficient strength of the polyamide cannot be obtained, and if it exceeds 100 parts by weight, the physical properties and surface smoothness of the molded product will deteriorate, and the effect of adding fatty acid ester of polyethylene sorbitan This is because they cannot obtain enough.

観改良効果はさほど大きくならず、しかもメンキや塗装
を施す場合の表面処理材と成形品との密着力が低下する
からである。In the present invention, the amount of fatty acid ester of polyoxyethylene sorbitan added is as follows with respect to 100 parts by weight of polyamide.
The amount is preferably 0.05 to 0.6 parts by weight. The reason is,
If the amount added is less than 0.05 part by weight, the effect of improving the surface appearance will be small, and if the amount added exceeds 0.6 part by weight, the effect of improving the surface appearance will not be so great, and moreover, it will be difficult to improve the surface appearance when polishing or painting. This is because the adhesion between the surface treatment material and the molded product decreases.
