Wear-resistant reinforced polyamide/polyoxymethylene alloy material and preparation method thereof

Abstract

The invention discloses a wear-resisting reinforced polyamide / polyoxymethylene alloy. The weight percentage of raw materials is as follows: 30%-60% of polyamide, 5%-25% of polyoxymethylene, 1%-20% of compatibilizer, compound Heat stabilizer 1.0%-3.0%, lubricant 0.5%-1.0% and reinforcing component 10%-30%. The alloy has excellent wear-resistant self-lubrication and mechanical properties, good dimensional stability, easy injection molding, adjustable color, and can well meet the needs of domestic and foreign markets. The preparation method has simple operation and is suitable for industrialized production.

Description

technical field

[0001] The invention relates to the field of polymer materials, in particular to a wear-resistant reinforced polyamide / polyoxymethylene alloy material and a preparation method thereof. Background technique

[0002] Polyamide is collectively referred to as nylon (Nylon), and the English name is Polyamide (referred to as PA). It is named after the repeated amide group - [NHCO] - in the main chain of the molecule. It is the largest output, most variety and most useful among the five general engineering plastics A class of basic resins with wide range and excellent comprehensive performance.

[0003] According to the specific molecular structure, nylon is divided into aliphatic nylon, semi-aromatic nylon and fully aromatic nylon. Among them, the main varieties of aliphatic nylon are nylon 6 (PA6) and nylon 66 (PA66), which account for more than 90% of polyamide production and have an absolute dominant position. Nylon 6 and Nylon 66 are tough translucent or ligh...
