Problems solved by technology

On the other hand, vinyl chloride-based resins are known to have insufficient light and heat stability, and are likely to undergo decomposition mainly due to dehydrohalogenation during thermoforming and product use.

Embodiment 1～84 and comparative example 1～10

[0168] According to the proportions shown in Tables 13 to 27, the vinyl chloride resin, the composition and other additives were blended with a Henschel mixer to obtain each vinyl chloride resin composition. The obtained vinyl chloride resin composition was calender-molded to produce a sheet. The roll kneading conditions were 165° C.×30 rpm×0.6 mm. Using the obtained sheet, dynamic heat stability, static heat stability, coloring resistance, heat coloring resistance, and transparency were evaluated by the following test methods. The evaluation results are collectively described in Tables 13-27.

Abstract

Provided are: a stabilizing agent that can impart excellent heat stability, coloring resistance, anti-thermal discoloration, etc. to a vinyl chloride resin, and can also impart excellent transparency to a vinyl chloride resin, if the vinyl chloride resin is used for an application where the material transparency is required; a vinyl chloride resin composition containing the same; and a molded body thereof. This stabilizing agent composition contains 5 to 2,500 parts by mass of a component (B) with respect to 100 parts by mass of a component (A), wherein component (A) is one or more organic acid zinc salts, and component (B) is one or more epoxy compounds having a glycidyl ether group and / or a glycidyl ester group.

Description

technical field [0001] The present invention relates to a stabilizer composition, a vinyl chloride resin composition containing the same (hereinafter also simply referred to as "composition" and "resin composition"), and a molded product thereof. Excellent thermal stability, coloring resistance, heat coloring resistance, etc., and a stabilizer composition capable of imparting excellent transparency to a vinyl chloride resin when the vinyl chloride resin is used in an application requiring transparency, and a stabilizer composition containing the same Vinyl chloride-based resin composition and its molded body. Background technique [0002] Vinyl chloride-based resins are excellent in flame retardancy, chemical resistance, mechanical stability, transparency, adhesiveness, printability, etc., and can easily change the hardness from hard to soft by adding plasticizers. Because it changes, it is used for various purposes. In particular, rigid vinyl chloride-based resin composit...
