Abstract

The invention discloses an antistatic polyvinyl chloride friction material. The antistatic polyvinyl chloride friction material is prepared from 0.7-2 parts of zinc ricinoleate, 2-3 part of polyvinyl butyral, 0.5-1 part of 8-hydroxyquinoline, 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 30-40% formalin, 0.2-0.3 part of triethanolamine, 0.3-0.5 part of alkylphenol ethoxylates, 2-3 parts of RC2540, 1-2 parts of potassium hexatitanate whiskers, 0.3-1 part of a titanate coupling agent kt105, 2-3 parts of dodecyl dimethyl betaine, 0.8-1 part of fatty acid diethanol amide, 5-7 parts of triethylene glycol di-2-ethylhexoate, 3-4 parts of calcium aluminate, 1-2 parts of manganese oxide and 3-5 parts of pentaerythritol. The antistatic polyvinyl chloride friction material is resistant to high temperature and friction, good in comprehensive performance and high in stability.

Description

Technical field [0001] The invention relates to the technical field of friction materials, in particular to an antistatic 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 properties,...
