Problems solved by technology

Fluoroplastics have excellent resistance to special environmental conditions and self-lubricating properties, but due to the stress of PTFE itself, the wear resistance is low, and the friction with the cable during use will cause friction damage to the surface of the fluoroplastics. And delamination, how to prepare a kind of fluoroplastic with good wear resistance and excellent tear resistance has become a technical problem to be solved at present

Abstract

The invention discloses a wear-resistant and tearing-resistant fluoroplastic, which is prepared from the following raw materials in parts by weight: 25 to 35 parts of polytetrafluoroethylene, 20 to 40 parts of polystyrene, 5 to 15 parts of polyethylene, 0.2 to 0.8 part of rosin, 0.2 to 0.8 part of pine tar, 0.2 to 0.8 part of dioctyl terephthalate, 1 to 3 parts of dicumyl peroxide, 0.2 to 0.8 part of tetramethylthiuram monosulfide, 20 to 40 parts of modified walnut shell fiber, 35 to 55 parts of limestone, 10 to 20 parts of aluminum borate whiskers, 2 to 10 parts of phosphorite, 5 to 10 parts of sodium antimonate, 2 to 8 parts of calcium sulfate, 1 to 3 parts of antioxidants 1010, 1 to 3 parts of antioxidants DNP and 1 to 3 parts of antioxidants 1076. The wear-resistant and tearing-resistant fluoroplastic has the advantages of good high-temperature resistant performance, good friction resistant performance and excellent tearing-resistant performance.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a wear-resistant and tear-resistant fluoroplastic. Background technique [0002] Fluoroplastics have excellent material properties, such as high and low temperature resistance, corrosion resistance, good electrical insulation, non-adhesive properties, etc., and were first used in high-tech military fields such as aviation and aerospace. As its use becomes more and more extensive, it is also widely used in various parts of the car. Fluoroplastics have excellent resistance to special environmental conditions and self-lubricating properties, but due to the stress of PTFE itself, the wear resistance is low, and the friction with the cable during use will cause friction damage to the surface of the fluoroplastics. And delamination, how to prepare a fluoroplastic with good wear resistance and excellent tear resistance has become a technical problem to be solved at present. Contents o...
