[0003] However, polyacetal resin lacks reactivity, and glass-based inorganic fillers also lack reactivity. Therefore, simply blending glass-based inorganic fillers with polyacetal resins and melting and kneading will result in poor adhesion between the two. Insufficient, in many cases, the expected improvement in mechanical properties cannot be obtained

Abstract

The present invention relates to a method for producing a polyacetal resin composition. [Problem] To provide a method for producing a polyacetal resin composition having excellent mechanical properties such as tensile strength, tensile elongation, flexural strength, and impact resistance, particularly excellent creep properties. [Solution] A method for producing a polyacetal resin composition, wherein (B) a glass-based inorganic filler obtained by surface treatment with a silane coupling agent is added to 100 parts by mass of (A) polyacetal resin 1 mass part to 100 mass parts of the material, (C) 0.0001 mass part to 0.5 mass part of at least one halide selected from magnesium halide and ammonium halide, and (D) a triazine derivative having a nitrogen-containing functional group 0.002 mass parts or more and 10 mass parts or less are melt-kneaded and manufactured.

Description

technical field [0001] The present invention relates to a method for producing a polyacetal resin composition. Background technique [0002] Polyacetal resins have excellent properties in terms of mechanical properties, thermal properties, electrical properties, sliding properties, moldability, impact resistance, and dimensional stability of molded products, and are widely used as structural materials and mechanical parts in electrical equipment, Auto parts, precision machinery parts, etc. Furthermore, in order to improve the mechanical properties of polyacetal resins, such as strength and rigidity, it is known to mix reinforcing materials such as glass-based inorganic fillers. [0003] However, polyacetal resin lacks reactivity, and glass-based inorganic fillers also lack reactivity. Therefore, simply blending glass-based inorganic fillers with polyacetal resins and melting and kneading will result in poor adhesion between the two. Insufficient, the expected improvement i...
