Washer material of cylinder cover bolt and preparation method of washer material

Abstract

The invention discloses a washer material of a cylinder cover bolt. The washer material is prepared from the following materials in parts by weight: 32 to 38 parts of carbon fibers, 10 to 15 parts of maleic anhydride grafted polyphenylene ether, 6 to 10 parts of bentonite, 11 to 16 parts of n-butyl methacrylate, 20 to 25 parts of ethylene acrylic acid, 9 to 13 parts of polyurethane, 11 to 14 parts of anilmomethyl triethoxy silane, 5 to 8 parts of carbon black, 6 to 10 parts of titanium dioxide, 13 to 16 parts of polycarbonate, 8 to 15 parts of paraffin, 7 to 12 parts of magnesium hydroxide, 2 to 5 parts of dioctyl sebacate, 6 to 8 parts of sodium fluoride, 15 to 20 parts of melamine, 12 to 15 parts of methyl cyclohexane, 22 to 24 parts of silica gel, 4 to 8 parts of thiourea, 6 to 9 parts of zinc n-butylxanthate, 2 to 6 parts of succinic acid, 3 to 8 parts of lactic acid, and 7 to 10 parts of oleic acid. The washer material of the cylinder cover bolt has good elasticity and good high temperature resistance, has a flame-retardant function, and has good abrasion resistance.

Description

technical field [0001] The invention relates to a gasket material for cylinder head bolts and a preparation method thereof. Background technique [0002] Plastic is a synonym for synthetic resin. It is a solid with high molecular material as the main raw material, which is artificially processed into a useful shape, but does not include fibers, rubber, coatings and adhesives. It can be said that plastic has the following three conditions: it is a polymer substance in terms of material, its shape has been artificially processed to form a useful shape, and it is solid under normal conditions. As the name suggests, plastic gaskets are made of plastic. In China, plastic gaskets are usually also called plastic washers, resin gaskets, plastic gaskets or nylon gaskets (the most common plastic gaskets in the domestic market are mostly made of nylon 66). . Compared with metal gaskets, it has excellent insulation, corrosion resistance, heat insulation and non-magnetic properties, an...
