Abstract
The invention discloses an automobile brake pad, and relates to the technical field of automobile accessories. The automobile brake pad is prepared from the following raw materials in parts by weight: 15-25 parts of silicon nitride ceramic powder, 20-40 parts of silicon carbide fiber, 5-10 parts of ceramic bonding agent, 3-5 parts of phenolic resin, 5-10 parts of rubber powder, 5-10 parts of frication powder, 20-30 parts of filler, 2-5 parts of nano-silica, 5-8 parts of sintering aids and 1-3 parts of defoaming agent. Compared with the prior art, the automobile brake pad is high in strength, good in high temperature resistance, small in heat attenuation, stable in friction coefficient and less in abrasion.
Description
Technical field
The present invention relates to technical field of automobile, especially a kind of automobile brake sheet.
Background technique
Brake block is the vital part in automobile brake system, it has significant impact to braking effect, be compressed in during brake on brake disc and produce friction, reach the object of vehicle deceleration, therefore, to the mainly good braking ability of the performance requirement of brake block, fading rate is little, restorability good, wear-resistant, noise free, good heat resistance etc.Current dish city brake block adopts semi-metallic brake pad or low metal brake block mostly, and semi-metallic brake pad exists the shortcomings such as brake noise is large, corner embrittlement, and the wearing and tearing of low metal brake block are comparatively large, high temperature friction stability is not good.Ceramic brake is the new product grown up in recent years, and it has the advantages such as stable friction factor, good thermostability and wear resistance, but intensity low, at high temperature easily crack.
Summary of the invention
The object of this invention is to provide a kind of automobile brake sheet, this brake block can solve existing ceramic brake and there is the problem that intensity is low, at high temperature easily crack.
In order to solve the problem, the technical solution used in the present invention is: this automobile brake sheet is made up of the raw material of following parts by weight: silicon nitride ceramic 15 ~ 25 parts, silicon carbide fiber 20 ~ 40 parts, ceramic bonding agent 5 ~ 10 parts, 3 ~ 5 parts, phenolic resin, rubber powder 5 ~ 10 parts, Frication powder 5 ~ 10 parts, filler 20 ~ 30 parts, nano silicon 2 ~ 5 parts, sintering aid 5 ~ 8 parts, defoamer 1 ~ 3 part.
In the technological scheme of above-mentioned automobile brake sheet, technological scheme can also be more specifically: silicon nitride ceramic 25 parts, silicon carbide fiber 30 parts, ceramic bonding agent 5 parts, 5 parts, phenolic resin, rubber powder 8 parts, Frication powder 10 parts, filler 25 parts, nano silicon 5 parts, sintering aid 6 parts, defoamer 2 parts.
Further, described filler is weight ratio is the blanc fixe of 1:1 and the mixture of Paris white.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect: main raw material silicon nitride ceramic and silicon carbide fiber are Inorganic Non-metallic Materials, and intensity is high, resistance to high temperature is good, heat fade is little, stable friction factor, weares and teares little.
