发明名称 POLYACETAL RESIN COMPOSITION
摘要 PROBLEM TO BE SOLVED: To obtain a resin composition exhibiting excellent corrosion-inhibiting ability, by compounding a polyacetal resin with a specific amount of a nitrogen- containing compound, such as melamine or its derivative and a polyamide, and at leastone type of boric acid. SOLUTION: A polyacetal copolymer produced by using a comonomer represented by the formula: wherein each of R1 -R4 represents H, an alkyl or a halogen-substituted alkyl and R5 represents methylene or oxymethylene (p=0 to 3), is preferably used as a polyacetal resin. This polyacetal resin composition is obtained by compounding 100 pts.wt. of the polyacetal resin with 0.05 to 5 pts.wt. of a hindered phenol antioxidant such as 2,2'-methylenebis(4-methyl-6-t- butylphenol), 0.001 to 5 pts.wt. of at least one type of nitrogen-containing compound selected from among melamine and its derivatives, a melamine- formaldehyde resin, a polyamide and the like, 0.001 to 3 pts.wt. of at least one type of boric acid selected from among orthoboric acid, metaboric acid, tetraboric acid and the like, and, if desired, an antistatic agent, an inorganic filler and the like; and kneading the resulting compound in an extruder or the like.
