Problems solved by technology

However, its wide application in the field of tribology is limited due to its low impact resistance, high water absorption, and high dry friction coefficient with tempered glass.
Polyethylene has a relatively low coefficient of friction, excellent self-lubricating properties, low water absorption and excellent impact toughness. Therefore, people blend polyamide and polyethylene to prepare alloy materials, but polyethylene has low surface hardness, Due to the defects of poor abrasive wear resistance and difficult processing, the existing polyamide composite materials still have the problem of poor mechanical properties and wear resistance

Abstract

The invention discloses a fiber-reinforced wear-resistant polyamide composite material and a preparation method thereof. The fiber-reinforced wear-resistant polyamide composite material is prepared from polyamide, glass fibers, butadiene-styrene-vinyl pyridine rubber, silicone powder, N,N-dimethylformamide, polyethersulfone, a poly-alpha-methylstyrene resin, tritolyl phosphate, epoxy soybean oil, polyethylene wax, a lubricant TAF, nano diamond, antioxidant 168, methylphenyl silicone oil, glass microspheres, decabromo diphenylethane, tantalum carbide and zirconite powder. By using the polyamide as the base material and the glass fibers as the reinforcer and adding the inorganic filler, antioxidant and other modifiying raw materials, the polyamide composite material has favorable tensile strength, bending modulus and notch impact strength. The added butadiene-styrene-vinyl pyridine rubber, poly-alpha-methylstyrene resin, polyethersulfone, nano diamond, tantalum carbide, zirconite powder, lubricant TAF, methylphenyl silicone oil, polyethylene wax and the like improve the impact resistance of the polyamide, lower the friction factor of the material and enhance the wear resistance of the material.

Description

technical field [0001] The invention relates to a polyamide material, in particular to a fiber-reinforced wear-resistant polyamide composite material and its preparation method and application. Background technique [0002] Composite materials are composed of two or more materials with different properties, which are composed of materials with new properties in the macro (micro) through physical or chemical methods. Various materials learn from each other in terms of performance and produce synergistic effects, so that the comprehensive performance of the composite material is better than that of the original constituent materials to meet various requirements. The development of modern high technology is inseparable from composite materials, and composite materials play a very important role in the development of modern science and technology. Such as large-scale municipal construction in the process of urbanization, the utilization and large-scale development of new energy...
