Title:
POLYACETAL RESIN COMPOSITION, AND SULFUR FUEL CONTACT PROVIDED WITH MOLDED ARTICLE OF POLYACETAL RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2014/119393
Kind Code:
A1
Abstract:
Provided is a polyacetal resin composition which, when made into a molded article, can maintain an excellent surface appearance for the molded article and can suppress the occurrence of cracks not just when brought into contact with a low-sulfur fuel but also when brought into contact with a high-sulfur fuel. The polyacetal resin composition according to the present invention comprises: 100 parts by weight of straight-chain polyacetal resin (A1); 0.1-3.0 parts by weight of a polyacetal copolymer resin (A2) having a branched structure or a cross-linked structure; 0.1-1.0 parts by weight of a hindered phenol oxidation inhibitor (B); 0.1-2.0 parts by weight of a calcium organic acid salt (C); 0.01-0.3 parts by weight of a formaldehyde reactive nitrogen compound (D); and 0.01-0.5 parts by weight of a phosphorus-based antioxidant (E). The polyacetal resin composition according to the present invention can inhibit the number of cracks generated to either "0", "1" or "2" in the figure, even after the molded article has been immersed in a high-sulfur fuel, and thus can suppress the leakage of high-sulfur fuel.
