Polyacetal resin composition

Abstract

Disclosed is a polyacetal resin composition which has metallic appearance, which can be molded into an article that generates a volatile organic compound (a VOC), particularly formaldehyde, therefrom at an extremely low level, and which has excellent weather resistance. Specifically, the polyacetal resin composition comprises: (A) 100 parts by weight of a polyacetal copolymer having a hemiformal terminal group at a content of 1.0 mmol / kg or less, a formyl terminal group at a content of 2.0 mmol / kg or less and an unstable terminal group at a content of 0.5 wt% or less; (B) 0.03 to 0.30 parts by weight of a hindered phenol antioxidant agent; (C) 0.01 to 1 part by weight of a guanamine compound; (D) 0.2 to 1 part by weight of a hindered amine stabilizer; (E) 0.1 to 1 part by weight of an ultraviolet ray absorber; and (F) 1 to 20 parts by weight of a metallic pigment.

Description

technical field

[0001] The present invention relates to a polyacetal resin composition which has a metallic appearance, significantly suppresses the generation of volatile organic compounds (VOC), and is excellent in weather (light) resistance. The resin composition can be suitably used for interior materials of automobiles and the like. Background technique

[0002] Polyacetal resin has various excellent properties, and its molded products can be used in a wide range of fields. However, with the rapid advancement of technology in the field of use, there is a tendency to require high characteristics for the polyacetal resin material used. . As such requirements, in the application field of automotive interior parts, etc., there are also those that are required to have excellent thermal stability, a small amount of volatile organic compounds derived from resins, excellent weather resistance, and a metallic appearance to impart a sense of luxury. The voice of polyacetal resi...
