Abstract

The invention discloses a high-temperature-resistant polytetrafluoroethylene formula. High-temperature-resistant polytetrafluoroethylene in the formula is prepared from, by weight, 15-20 parts of chlorinated polyethylene, 12.5-18 parts of polypropylene, 1.5-5 parts of isopropyl alcohol diethyl ether, 6.5-10 parts of silicon dioxide, 6-15 parts of polyphenylene sulfide, 5.5-15 parts of polystyreneresin and 15-20.5 parts of hexafluoropropylene. According to the high-temperature-resistant polytetrafluoroethylene formula in the mode, the formula still has the extremely-good bonding resistance after high-temperature baking, the performance is also not easily changed after continuous high-temperature using, and the high temperature resistance is good.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high-temperature-resistant polytetrafluoroethylene formula. Background technique [0002] PTFE is the main variety of fluoroplastics. Currently, the three major products supplied to the market are suspension resin, dispersion resin and deep shrinkage dispersion. Suspension method PTFE is mainly used for sealing rings, gaskets, chemical pumps, valves, Pipe fittings and equipment linings, electrical insulating parts and films, etc. Dispersion method PTFE is mainly used for corrosion resistance, high temperature resistance, high dielectric wire and cable, chemical pipeline lining, etc. PTFE concentrated dispersion is mainly used for anti-stick coating and impregnated glass cloth, asbestos, etc. in the fields of food, textile, paper and so on. With the continuous development of material application technology, the three major shortcomings of PTFE materials: cold flow, d...
