Antimicrobial anticorrosive polyvinyl chloride friction material and preparation method thereof

Abstract

The invention discloses an antimicrobial anticorrosive polyvinyl chloride friction material which is prepared from the following raw materials in parts by weight: 1-2 parts of sodium benzoate, 4-7 parts of butyl benzyl phthalate, 1-2 parts of methyl p-hydroxybenzoate, 0.2-0.4 part of N,N-diethylaniline, 2-3 parts of ethyl methyl p-hydroxybenzoate, 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 polyoxyethylene, 2-3 parts of dialkyl pentasulfide RC2540, 1-2 parts of potassium hexatitanate whisker, 0.3-1 part of titanate coupling agent kt105, 3-4 parts of aluminum ammonium sulfate, 0.8-1 part of acetal amide oleate, 3-4 parts of zinc borate hydrate and 0.9-1 part of copper 8-hydroxyquinoline. The polyvinyl chloride friction material has the advantages of high temperature resistance, friction resistance, favorable comprehensive properties and high stability.

Description

technical field [0001] The invention relates to the technical field of friction materials, in particular to an antibacterial and antiseptic 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...

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
