Problems solved by technology

The above three types of resins have their own shortcomings. Unmodified phenolic resin has general high temperature resistance and general elasticity. Brake pads made of high temperature resistant modified phenolic resin have poor elasticity and high hardness. Modified phenolic resin with enhanced elasticity has high temperature resistance. poor performance
[0003] Carbon materials can improve the high temperature resistance of brake pads, among which carbon fiber has an excellent reinforcing effect, graphite materials have a lubricating effect, hard carbon materials can enhance the overall wear resistance of friction materials, and can significantly improve the wear resistance of friction materials. High temperature and high speed performance, but often a carbon material used in conjunction with an adhesive will have certain shortcomings

Abstract

The invention discloses a multielement resin base carbon compound disc-type braking pad and a preparation method thereof. The braking pad is obtained by carrying out mould pressing and forming once on the following raw materials: unmodified phenolic resin, organosilicone modified phenolic resin, polyacrylate modified phenolic resin, polyacrylonitrile carbon fiber, artificial granular graphite, natural crystalline flake graphite, granular coke, silicon carbide, aramid pulp, compound mineral fiber, steel fiber, red copper powder, ferrous sulfide and barium sulfate. The product disclosed by the invention has the advantages of high temperature resistance, ablation resistance, small heat expansion coefficient, high specific strength, high specific modulus, good abrasion resistance, low noise, excellent initial performance, short breaking-in period, small heat fade, long service life, excellent pedal comfort degree, excellent high temperature and high speed performance and stable abrasion grade under different braking conditions, the effect on considering the good abrasion resistance and low noise is achieved, no dust is generated during braking, and various materials are all environment-friendly environment-protection materials. The multielement resin base carbon compound disc-type braking pad also has the function of automatically cleaning the braking disc.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a multi-component resin-based carbon composite disc brake pad and a preparation method thereof. Background technique [0002] Traditional automobile brake pads are made of a single phenolic resin as a binder, mixed with reinforcing fibers and friction performance modifiers in a certain proportion and then hot-pressed. According to the use of phenolic resins, there are three main categories: unmodified phenolic resins, high temperature-resistant modified phenolic resins and reinforced elastic modified phenolic resins. The above three types of resins have their own shortcomings. Unmodified phenolic resin has average high temperature resistance and average elasticity. The brake pads made of high temperature modified phenolic resin have poor elasticity and high hardness. Enhanced elasticity modified phenolic resin has high temperature resistance. Poor performance. [0003] Carbo...
