Abstract
The invention discloses a kaolin modified polyvinyl chloride friction material. The kaolin modified polyvinyl chloride friction material is prepared from, by weight, 5-7 parts of kaolin, 2-3 parts of phthalic anhydride, 1-2 parts of monopotassium phosphate, 140-170 parts of polyvinyl chloride, 6-8 parts of tetraethoxysilane, 0.01-0.02 part of 1,3,5-trimethylbenzene, 37-40 parts of melamine, 50-60 parts of formaldehyde water solution of 37-40%, 0.2-0.3 part of triethanolamine, 0.3-0.5 part of alkylphenol polyoxyethylene ether, 1-2 parts of potassium hexatitanate whiskers, 0.3-1 part of a titanate coupling agent kt, 0.6-1 part of hexamethyl cyclotrisiloxane, 0.5-1 part of alkylated diphenylamine, 1-2 parts of polyglycerol fatty acid ester, 1-2 parts of benzyl triethyl ammonium bromide, 5-6 parts of trinonylphenyl phosphate, 0.1-0.2 part of zinc cyanurate and 2-3 parts of dialkyl pentasulfide RC2540. The kaolin modified polyvinyl chloride friction material is resistant to high temperature and friction, high in comprehensive performance and high in stability.
Description
Technical field [0001] The invention relates to the technical field of friction materials, in particular to a kaolin modified polyvinyl chloride friction material and a preparation method thereof. Background technique [0002] Tribological materials can be divided into anti-friction materials, wear-resistant materials and friction materials according to the working conditions and requirements of friction elements. According to the type of material, it is divided into metal tribological materials, inorganic non-metallic tribological materials and polymer tribological materials. The perishable characteristics of metal materials hinder its application in special occasions such as navigation or chemical industry; ceramic materials Brittleness is more serious hindering its application, especially the residual pores of ceramic materials in the sintering process have a considerable impact on performance; polymers and their composite materials have excellent physical and chemical propert...
