Abstract

The invention provides a high-performance cold and heat resistant PPS, PTFE and MC nylon alloy mainly suitable to be used for manufacturing machinery industry, electronic appliance, automobile industry, home appliance and chemical industry products resisting high and low temperatures. The alloy comprises the raw materials of, by weight, (1) 21-39.6 parts of PPS, (2) 15-20 parts of PTFE; (3) 10-20 parts of MC nylon, (4) 5-8 parts of a toughening agent, (5) 30 parts of alkali-free glass fiber, (6) 0.2-0.5 parts of an antioxidant, and (7) 0.2-0.5 parts of a processing additive. The component are mixed for 1-2min in a mixer, and the mixture is subjected to extrusion granulation in a twin-screw extruder, such that the alloy is obtained. The material provided by the invention has cold resistance, heat resistance, abrasion resistance, corrosion resistance, high electrical performance and high physical performance. The material can be normally used within a temperature range of -20 DEG C to 300 DEG C.

Description

technical field [0001] The invention relates to the field of polymer materials, especially a high-performance cold-resistant, heat-resistant, wear-resistant and corrosion-resistant PPS, PTFE, MC nylon alloy, which is mainly suitable for manufacturing machinery industry, electronic appliances, and automobile industry in high and low temperature resistant occasions. , household appliances, chemical industry, etc. Background technique [0002] Polyphenylene sulfide (PPS) is a thermoplastic special engineering plastic with excellent comprehensive properties. Its outstanding features are high temperature resistance, corrosion resistance and superior mechanical properties. PPS is a sulfur-containing aromatic polymer. Linear PPS becomes a thermosetting plastic after being cross-linked above 350 ° C. PPS with a branched chain structure is a thermoplastic. It has excellent electrical insulation (especially high-frequency insulation), white hard and brittle, and there is a metallic s...
