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...
