Abstract

The invention discloses a plastic blend friction material which is prepared from the following raw materials in parts by weight: 37-40 parts of melamine, 50-60 parts of 37-40% formalin, 4-6 parts of bentonite, 0.7-1 part of copper 8-hydroxyquinoline, 0.1-0.2 part of nonyl phenol, 10-16 parts of liquid ethylene propylene diene monomer rubber, 0.2-0.4 part of sp80, 3-4 parts of epoxy octyl stearate, 140-170 parts of polyvinyl chloride, 6-8 parts of ethyl orthosilicate, 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, 0.1-0.2 part of lithium naphthenate, 0.6-1 part of butyl tin mercaptide, 1-2 parts of ammonium polyphosphate, 1-2 parts of citric acid and 0.01-0.02 part of 1,3,5-trimethylbenzene. The plastic blend friction material has the advantages of high temperature 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 a plastic blend 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 properties, light wei...
