Abstract
The invention discloses a low-thermoplasticity high-wear-resistance composite material. The composite material is prepared from, by volume, 50-90 parts of a thermoplastic engineering plastic matrix, 1-50 parts of fluororesin, 1-50 parts of chopped fibers and auxiliary agents. The composite material has advantages that by reasonable control of a ratio of high-modulus reinforcement fibers to fluororesin, migration of wear-resistant fluororesin on an abrasion surface in a friction wear process can be promoted, and accordingly wear resistance and mechanical performances of the composite material are improved while the friction coefficient of the material is lowered; the prepared composite material can be used as high-performance multipurpose modified engineering plastic and has high economic benefit and application value; in addition, a preparation process of the material is simple in operation, technically mature and quite convenient for industrial production.
Description
technical field [0001] The invention relates to the field of polymer materials, in particular to a thermoplastic composite material with low wear resistance and a preparation method thereof. Background technique [0002] Self-lubricating engineering plastics such as polyamide 6, polyoxymethylene, polyphenylene sulfide and other materials have high rigidity, small creep, light weight, high mechanical strength, corrosion resistance, heat resistance, wear resistance, low cost, good electrical insulation, etc. Advantages, gradually replacing metal materials in the field of transmission has been widely used. However, the friction coefficient and wear amount of a single engineering plastic are still relatively large, and the application in some demanding fields is limited. The friction and wear properties of engineering plastics can be improved and their application range can be broadened by strengthening and filling modification of engineering plastics. Therefore, there is an u...
