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...
