Title:
POLYACETAL RESIN COMPOSITION AND FUEL CONTACTOR PROVIDED WITH MOLDED ARTICLE OF THE POLYACETAL RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2016/002259
Kind Code:
A1
Abstract:
Provided is a polyacetal resin composition which, when formed into a molded article, minimizes degradation caused by contact with a fuel. This resin composition contains (A) 100 parts by weight of a polyacetal copolymer resin, (B) 0.1-1.0 parts by weight of a hindered phenol-based antioxidant, (C) 0.1-2.0 parts by weight of a divalent metal oxide, and (D) 0.5-3.0 parts by weight of an alkylene oxide adduct of an alkylamine and/or an alkylene oxide adduct of an alkylene diamine. Component (C) preferably contains magnesium oxide and/or zinc oxide, and component (D) is preferably one or more types selected from among general formulae (1) to (3). In these general formulae, X is represented by (C2H4O)m(C3H6O)nH, and m and n are each an integer of 0 or higher. In addition, R1 is an alkyl group having 12-18 carbon atoms, and R2 is an alkylene group having 2 or 3 carbon atoms.
