のが現状である。Thermoplastic polyester resin containing ethylene terephthalate as the main repeating unit and having an intrinsic viscosity of 0.33 or more (hereinafter simply referred to as thermoplastic polyester resin) has a molded product that has transparency, mechanical strength, gas barrier properties, and non-toxicity. It is widely used as a variety of relatively thin-walled containers for beverages, cosmetics, etc. due to its excellent properties such as excellent elasticity and low calorie burn when discarded and incinerated. Because it is difficult to mold thick-walled polyester resin moldings, used thermoplastic polyester resin moldings are not reused as materials for other synthetic resin moldings, and are immediately disposed of by incineration. The current situation is that

た構・成から成るものである。The composition for molding a thick-walled synthetic resin molded article of the present invention is characterized in that the synthetic resin component in the composition has a water content of 0.07 to θ and an intrinsic viscosity of 0.55 or more, which is adjusted to a lI weight coefficient. It is composed of a mixed resin of 20 to 7θ weight percent of a plastic polyester resin, a polyethylene resin of 15 weight percent or more, and a polypropylene resin of 15 weight percent or more, and the molding composition contains such synthetic resin components, dyes, and pigments. It consists of a composition in which colorants such as and other additives are appropriately added and contained as necessary.

いることが必要である。In the molding composition of the present invention, the thermoplastic polyester resin constituting the main synthetic resin component in the composition is adjusted to within a range of 20 to 70% by weight of the total resin components, and its water content is 0. It is necessary that the weight ratio be adjusted within the range of .07 to .07.

のである。This is because the molding composition of the present invention contains enough moisture to form the thermoplastic polyester resin in the composition, and is used in the melting, kneading, and forming steps of the molding composition. During the shaping process, some of the ester bonds in the thermoplastic polyester resin are hydrolyzed to form a thermoplastic polyester resin containing oligomers, and the oligomers newly generated by hydrolysis are
This allows the filler to function in the thick-walled molded article, and at the same time imparts shapeability to the molding composition of the present invention.

構成されていることが必要である。The polyethylene resin in the synthetic resin component is extremely immiscible with the thermoplastic polyester resin, which is the main component in the synthetic resin, and the polypropylene resin has the effect of creating a pearly marble pattern. This is because it acts as an adhesive to prevent delamination between the plastic polyester resin and the plastic polyester resin, and at the same time provides smoothness to the surface of the resulting thick-walled molded product, making it a densely textured molded product. In the molding composition of the present invention, it is necessary that the synthetic resin component in the composition is composed of a mixed resin of a plastic polyester resin, a polyethylene resin, and a polypropylene resin.

現象が発生しやすくなるという欠点を生ずる。In a synthetic resin component consisting of a mixed resin of thermoplastic polyester resin, polyethylene resin, and polypropylene resin, if the thermoplastic polyester resin exceeds 70% by weight, the molding composition becomes hard and non-sticky. However, the resulting molded product is brittle, easily cracked, and has no strength, resulting in an inferior product.
If the weight is less than the weight ratio, the composition itself has poor fluidity, resulting in a disadvantage that it becomes difficult to mold a thick-walled molded article as the desired product. In addition, the thermoplastic polyester resin used is
If the water content is less than 0.07% by weight, it will be difficult to hydrolyze the thermoplastic polyester resin during the melting, kneading, and molding processes of the molding composition. The molding operation becomes difficult, and if the moisture content is 0. If it exceeds the weight percentage, the foaming phenomenon during the molding process will be severe and the surface of the resulting thick-walled molded product will be rough and rough, which is not only a disadvantage, but also makes the molding operation itself difficult. Also occurs. In addition, in the molding composition of the present invention, a polyzolopyrene resin is used which, in combination with the thermoplastic polyester resin which is the main synthetic resin component in the composition, gives the resulting thick-walled molded product a pearly marble pattern. If this is less than the / weight ratio of all resin components, it will be difficult to make the resulting thick-walled molded product have a clear pearly marble pattern, and the difference between the thermoplastic polyester resin and the polypropylene resin will be Regarding the polyethylene resin that has an adhesive effect, this is the /
If the weight ratio is less than 30%, the adhesion effect of the resin is not sufficient, resulting in a disadvantage that delamination tends to occur between the thermoplastic polyester resin component and the polypropylene resin component in the resulting thick-walled molded product.

The melting point of the resin is low, and the molding temperature is higher than the melting point of polyethylene resin or polyzolopyrene resin, specifically, injection molding at a temperature of about 270±/ta℃ and a pressure of about /3Ky/(1)2. can be molded into a thick-walled molded product with a pearly marble pattern that appears due to the extreme non-miscibility between the thermoplastic polyester resin and the polypropylene resin. It is.

である。The composition for molding a thick-walled molded object of the present invention has the above structure, and as a synthetic resin component in the molding composition, a thermoplastic polyester resin whose moisture content is adjusted to a predetermined value; A molding composition whose main component in the synthetic resin component is thermoplastic polyester resin, which has traditionally been difficult to mold into thick-walled molded objects by using a mixed resin of polyethylene resin and polypropylene resin. Because it has the ability to be easily molded into a thick-walled molded product with a marble pattern with pearlescent holes, it is a used thermoplastic that has been considered to have no use in the past. Crushed polyester resin moldings can be used as the thermoplastic polyester resin component, which not only reduces material costs but also allows for the reuse of used thermoplastic polyester moldings. It also has great effects and effects in terms of pollution prevention.
