ている。2. Description of the Related Art A vinyl chloride resin composition for powder molding is mainly composed of a powdery vinyl chloride resin obtained by a suspension polymerization method or the like, which is dry-blended with a plasticizer.
Depending on the purpose of use, various additives such as stabilizers, pigments, lubricants and fillers are mixed. The main use of the vinyl chloride-based resin composition for powder molding is automobile interior material moldings, and the interior material is usually used as a laminate by injecting and foaming urethane resin. When a urethane resin is injected and foamed into a vinyl chloride resin molded product, the amine compound in the foamed urethane resin causes an inconvenient phenomenon such as deterioration and deterioration of the vinyl chloride resin molded product. In particular, this phenomenon is caused by heat and light. It is significantly promoted in the presence. For the purpose of preventing the deterioration and deterioration of the molded article by this amine compound, that is, as an amine resistance measure, in recent years, a method of blending barium perchlorate and sodium perchlorate with a vinyl chloride resin composition has been adopted. It has been found that chloric acid treated hydrotalcite can also be used for similar purposes.
