Antistatic polyvinyl chloride friction material and preparation method thereof

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,...

Problems solved by technology

The research on polymer-based mesoporous composites is still in its infancy, and there are some common problems in the preparation process: (1) how to effectively modify the surface of mesoporous materials to improve the interfacial compatibility between the two phases, and at the same time, the surface modification can not cause The blockage of the pore openings of mesoporous materials affects the entry of monomeric small molecules or macromolecular chains
