含んだ熱可塑性ポリエステル樹脂となし。Further, a molding composition is used in which colorants and other additives are appropriately added and mixed as necessary. The thermoplastic polyester resin, which is the main synthetic resin component in the molding composition used in the present invention, is adjusted to within a range of 20 to 70% by weight of the total resin components in one composition, and its water content is 0.0. /~0. It is necessary to adjust the amount within the range of 11% by weight. This is because, in the method for producing a thick-walled molded article of the present invention, the molding composition used contains enough moisture to form a thermoplastic polyester resin, and the melting and mixing steps in the molding process of the thick-walled molded article are carried out in advance. During the kneading and shaping process, some of the ester bonds in the thermoplastic polyester resin are hydrolyzed, creating a thermoplastic polyester resin containing orythemer.

者の混合樹脂で構成されていることが必要である。The polyethylene resin in the synthetic resin component is 1. The polypropylene resin, which has an extremely non-miscible property with the thermoplastic polyester resin which is the main component in the synthetic resin, has the effect of creating a pearly marble pattern, and the above-mentioned heat treatment. A substance that acts as an adhesive to prevent delamination between the plastic polyester resin and the plastic polyester resin, and also provides smoothness to the surface of the resulting thick-walled molded product, making it a densely textured molded product. Therefore, in the molding composition used in the present invention, the synthetic resin components in the composition include a thermoplastic polyester resin, a polyethylene resin, and a polyzolopyrene resin.
It is necessary that the material be made of a mixed resin of different types.

については。If the thermoplastic polyester resin exceeds 70% by weight in the mixed resin of thermoplastic polyester resin, polyethylene resin, and polyzolopyrene resin that is the synthetic resin component in the molding composition used in the present invention, the molding composition will become hard. However, if it is less than 20% by weight, the composition itself will have poor fluidity. Unfortunately, there arises a drawback that the molding operation of the desired product, the thick-walled molded body, becomes difficult. In addition, the thermoplastic polyester resin used has a moisture content of 0.07% by weight.
If it is less than that, it will be difficult to hydrolyze the thermoplastic polyester resin during the melting, kneading, and molding processes of the molding composition, and the molding operation of the desired product, a thick-walled molded product, will be difficult. Moreover, the moisture content is 0. If the weight percentage is exceeded, the foaming phenomenon during the molding process will be severe, and the resulting thick-walled molded product will not only have a rough and rough surface, but also have the drawback that the molding operation itself will be difficult. arise. In addition, in the molding composition used in the present invention, the resulting thick-walled molded product exhibits a pearly marble pattern in combination with the thermoplastic polyester resin, which is the main synthetic resin component in the composition. Regarding polypropylene resin, if it is less than 75% by weight of the total resin components, the appearance of pearly marble pattern in the thick molded product obtained is poor, and the difference between thermoplastic polyester resin and polypropylene resin is As for the polyethylene resin that acts as an adhesive between.

う欠点を生ずる。If this amount is less than 75% by weight of the total resin component, the adhesive effect of the resin will not be sufficient, and delamination phenomenon will occur between the thermoplastic polyester resin component and the polyzolopyrene resin component in the resulting thick-walled molded product. This has the disadvantage that it becomes easy to use.

A molding composition containing dyes, pigments, and other additives as appropriate is heated to a temperature of about 250 to 250°C, which is lower than the melting point of thermoplastic polyester resin and higher than the melting point of polyethylene resin or polypropylene resin. It consists of injection molding at 2qO℃, specifically injection molding using a pressure of about 15Kp/ff12, followed by slow cooling.
A thick-walled molded article having a marble pattern with a pearly feel, which is created based on the extreme non-fusibility between the thermoplastic polyester resin and the polypropylene resin, is obtained.
