Problems solved by technology

[0003] The main raw materials of wear-resistant nylon used in the market are: molybdenum trisulfide, polytetrafluoroethylene, etc., but if one is used alone, the increase in wear and hardness will hardly meet the requirements. If the two are added at the same time, the increase in material density Difficult to manufacture, and materials are not compatible

Abstract

The invention discloses an abrasion-resistant PA66 composite material.The abrasion-resistant PA66 composite material is mainly composed of, by weight, 60-90 parts of PA66, 10-30 parts of glass fibers, 2-5 parts of molybdenum trisulfide powder capsules, 0.1-0.3 part of antioxidant and 1-3 parts of compatibilizer.The abrasion-resistant PA66 composite material has the advantages that the problem of low abrasion resistance of single materials is solved, and mechanical performances are improved.

Description

technical field [0001] The invention relates to a wear-resistant PA66 composite material. Background technique [0002] Nylon is the general name of polyamide, and it is the extrusion resin with the largest output, the most varieties, the widest application and the best comprehensive performance among the five general-purpose engineering plastics. Among polyamide resins, nylon 6 and nylon 66 have the largest output and consumption, accounting for about 90% of the total polyamide. Nylon has outstanding characteristics in terms of mechanical, chemical, and thermal properties. [0003] The main raw materials of wear-resistant nylon used in the market are: molybdenum trisulfide, polytetrafluoroethylene, etc., but if one is used alone, the increase in wear and hardness will hardly meet the requirements. If the two are added at the same time, the increase in material density Manufacture is difficult and the materials are not compatible. [0004] The high-abrasion nylon materials...
