Title:
ポリアセタール樹脂組成物及びその製造方法
Document Type and Number:
Japanese Patent JP5612430
Kind Code:
B2
Abstract:
The present invention provides a polyacetal resin composition having excellent mechanical properties such as tensile strength, bending strength, and impact strength, and excellent dispersibility of cellulose fiber powder. This polyacetal resin composition comprises: 100 parts by weight of a straight-chain polyacetal resin (a) obtained by copolymerizing 99.9-90.0 wt% trioxane and 0.1-10.0 wt% of a monofunctional cyclic ether; 0.1-50 parts by weight of a branched polyacetal resin (b) obtained by copolymerizing 99.89-89.0 wt% trioxane, 0.1-10.0 wt% of a monofunctional cyclic either, and 0.01-1.0 wt% of a polyfunctional glycidyl ether having 2-4 functional groups; 10-150 parts by weight of a cellulose fiber powder (c) having an aspect ratio of 5-25 and an average fiber length of 150-350µm; 0.01-3 parts by weight of a hindered phenol anti-oxidation agent (d); and 0.01-3 parts by weight of at least one type of nitrogen-containing compound (e) selected from an aminotriazine compound, a guanamine compound, a hydrazide compound, and a polyamide.
