Abstract

The invention discloses an insulating polyvinyl chloride friction material. The insulating polyvinyl chloride friction material is prepared from, by weight, 6-8 parts of kieselguhr, 1-2 parts of molybdenum disulfide, 140-170 parts of polyvinyl chloride, 6-8 parts of ethyl orthosilicate, 0.01-0.02 part of 1,3,5-trimethylbenzene, 37-40 parts of melamine, 50-60 parts of 37-40% formalin, 0.2-0.3 part of triethanolamine, 0.3-0.5 part of alkylphenol ethoxylate, 2-3 parts of dialkyl pentasulfide RC2540, 1-2 parts of potassium hexatitanate whiskers, 0.3-1 part of a titanate coupling agent kt105, 2-3 parts of waste rubber powder, 1-1.6 parts of zinc acetate, 2-3 parts of tetrahydrofurfuryl alcohol, 0.5-1 part of glycollic amide, 0.3-1 part of pyromellitic dianhydride, 2-4 parts of poly(butyl acrylate) and 1-2 parts of cellulose glycolate. The insulating polyvinyl chloride friction material is resistant to high temperature and friction, good in overall performance and high in stability.

Description

technical field [0001] The invention relates to the technical field of friction materials, in particular to an insulating polyvinyl chloride friction material and a preparation method thereof. Background technique [0002] Tribological materials, according to the working conditions and requirements of friction elements, can be divided into anti-friction materials, wear-resistant materials and friction materials. 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 their application in special occasions such as navigation or chemical industry; ceramic materials Brittleness hinders its application more seriously, especially the remaining pores of ceramic materials in the sintering process have a considerable impact on performance; polymers and their composite materials have excellent physical and chemical prop...
