In weight percent, the brake pad comprises 5-15% of adhesives, 20-30% of reinforcing materials, 20-30% of frictional property conditioning agents and 30-50% of packing in formula, wherein the adhesives include phenolic resin, silicone modified phenolic resin and butyronitrile modified phenolic resin, the reinforcing materials include carbon fibers, ceramic fibers and aramid pulp, the frictional property conditioning agents include grinding agents and lubricating agents, the grinding agents include aluminum oxide, ferric oxide, magnesium oxide and frictional powder, the lubricating agents include graphite, sulfide and mica, and the packing comprises barium sulfate, potassium titanate and magnesium oxide. The carbon-ceramic based brake pad has negative temperature coefficient, stable chemical performance and resistance to strong acid and strong alkali, and is nonhazardous and extremely high in mechanical performance.
Description
Technical field
The present invention relates to the preparation of the brake block in the auto industry field, especially a kind of charcoal Tao Ji brake block.
Background technique
The brake block processing technology is following: batch mixing, hot-forming, grinding, spray paint, installation accessories, seal mark, packing.High temperature decline and high stability are brake block two big vital performance requirements, and it directly affects braking safety and comfortable feel.Though can improve decline property to a certain extent through thermal ablation technology, can not address this problem, and also easy other the problem together of ablating, such as: shearing force descends, and is prone to flake; The uniformity of ablating; And consistency of product etc.
Summary of the invention
The objective of the invention is to change the internal structure of brake block through adding reinforcing fibers such as graphite fiber, ceramic fiber, improve the intensity of brake block, thereby make brake block when High Temperature And Velocity, performance is more stable, improves comfort level.The present invention utilizes ceramic fiber, graphite fiber as main material; Utilize ceramic fiber, graphite fiber to have characteristics such as fusing point height, mechanical behavior under high temperature is good, density is low; Specific surface area is big, and is high temperature resistant, with characteristics such as other materials appearance property are good; Be used for the preparation of brake block, improve the High Temperature And Velocity stability of brake block.Its technological scheme is to comprise Bond, reinforcing material, frictional property regulator and filler in the charcoal Tao Ji brake block prescription, and described Bond comprises phenolic resin, silicon phenol-formaldehyde resin modified and butyronitrile remodeling phenolic resin, and weight of binder percentage is 5-15%; Reinforcing material is graphite fiber, ceramic fiber and aramid fibre pulp, and the reinforcing material weight percentage is for being 20-30%; Frictional property regulator comprises lapping paste and oiling agent, and lapping paste comprises aluminium sesquioxide, iron oxide, magnesia and friction powder, and oiling agent comprises graphite, sulphide and mica, and the frictional property regulator weight percentage is for being 20-30%; Filler comprises barium sulphate, potassium titanate and magnesia, and the weight percentage of filler is for being 30-50%.After adopting above-mentioned prescription owing to add ceramic fiber as reinforcing material, with cashew nut oil modified alkyd resin, nitrile butadiene rubber blend as matrix; Add suitable frictional behaviour modifier; Prepare new-type friction material. graphite fiber is by the novel inorganic nonmetallic material of incomplete graphite crystallization along a kind of polycrystalline of fiber axially-aligned, has " turbostratic graphite " structure, and the effect graphite fiber that in friction material, can play reinforcing material and solid lubricant simultaneously has characteristics such as low density, high tenacity, high-modulus, high temperature resistant, resist chemical, low resistance, high heat conduction, low-thermal-expansion, resistance to chemical attack; It is little that specific strength and specific modulus are superior to other inorfil crystal whisker of hexa potassium titanate thermal conductivitys; And has negative temperature coefficient, stable chemical performance, anti-strong acid; Highly basic and nonhazardous, mechanical property is high.
