Abstract

The invention relates to the technical field of brake materials, in particular to a friction material, an organic carbon ceramic brake pad prepared from the friction material and used for an abrasion-resistant coating braking disc, and a preparation method and application of the organic carbon ceramic brake pad. The friction material is prepared from the following raw materials in parts by weight:3-5 parts of carbon fibers, 10-15 parts of steel fibers, 5-10 parts of mineral fibers, 8-12 parts of modified phenolic resin, 5-10 parts of powdered nitrile rubber, 6-10 parts of cashew nut oil frictional powder, 10-20 parts of precipitated barium sulfate, 1-3 parts of acrylic fibers, 2-4 parts of silicon carbide, 5-10 parts of soft kaolin and 9-12 parts of zirconium silicate. The preparation method of the organic carbon ceramic brake pad comprises the steps of pressing, solidifying and forming. The organic carbon ceramic brake pad for the abrasion-resistant coating braking disc is stable instructure, good in heat resistance and friction performance, simple in preparation process and short in preparation period, the matching property between the organic carbon ceramic brake pad and the abrasion-resistant coating braking disc is good, an abrasion-resistant friction pair is made of the organic carbon ceramic brake pad and the abrasion-resistant coating braking disc, and the service life of the braking disc of an automobile, or a new energy vehicle or a bullet train can be effectively prolonged.

Description

technical field [0001] The invention belongs to the technical field of brake materials, and in particular relates to a friction material, an organic carbon ceramic brake pad for a wear-resistant coating brake disc prepared therefrom, a preparation method and application thereof.
