Abstract
The invention relates to an organic ceramic brake pad for a road vehicle carbon ceramic brake disc and a preparation method thereof, wherein the raw materials comprise the following components in percentage by weight: 1 to 4 percent of phenolic resin, 1 to 5 percent of boron modified phenolic resin, 4 to 15 percent of aluminum metaphosphate, 3 to 7 percent of sodium silicate, 1 to 3 percent of ammonium fluoride, 1 to 5 percent of magnesium oxide, 3 to 5 percent of copper oxide, 2 to 6 percent of aluminum powder, 1 to 6 percent of carbon fiber, 1 to 6 percent of aramid pulp, 8 to 15 percent of steel fiber, 15 to 20 percent of reduced iron powder, 6 to 12 percent of red copper powder, 1 to 3 percent of antimony oxide, 5 to 8 percent of zinc borate, 2 to 6 percent of antimony trisulfide, 4 to 6 percent of molybdenum disulfide, 5 to 8 percent of calcined petroleum coke, 1 to 5 percent of aluminum titanate, 1 to 4 percent of titanium oxide, 5 to 12 percent of zirconium oxide, 4 to 8 percent of silicon carbide and 2 to 6 percent of chromium trioxide. The brake pad has good friction coefficient stability and wear resistance, and solves the technical bottleneck of the existing carbon ceramic brake disc brake pad.
Description
Technical Field
The invention belongs to the technical field of friction plates for vehicles, and particularly relates to an organic ceramic brake block for a road vehicle carbon ceramic brake disc and a preparation method thereof.
Background
Recently, as the requirements of the electric vehicle for light weight increase and the production cost of the carbon ceramic disc continuously decrease, the carbon ceramic brake pair is about to come into wide market space.
The brake disc material widely used at present is mainly common cast iron, and the material is easy to fade and rust. Compared with cast iron discs, the carbon ceramic discs have the characteristics of light weight, high temperature resistance, abrasion resistance, corrosion resistance and the like, and have stable friction coefficient and long service life. Although the development of the carbon ceramic brake disc is mature, the research of the brake pad matched with the carbon ceramic brake disc is little. Most of the traditional carbon ceramic brake disc organic composite material brake pads adopt single high-temperature resistant resin as an adhesive, and although the temperature resistance is greatly improved, the production difficulty is high, the heat fading problem still exists under extreme conditions, and the ignition phenomenon is obvious; the carbon ceramic brake disc brake pad adopting the ceramic adhesive has the advantages of temperature resistance, wear resistance, poor brake comfort and inapplicability to road vehicles.
In view of the foregoing, there is a need for an organic ceramic brake pad that has good heat fade resistance, a moderate coefficient of friction, a smooth braking, wear resistance, and a carbon ceramic disk matching.
Disclosure of Invention
The invention aims to provide an organic ceramic brake block which has good heat fading resistance, moderate friction coefficient, stable braking, wear resistance and capability of matching a carbon ceramic disc.
The above purpose is achieved by the following technical scheme: the organic ceramic brake pad for the road vehicle carbon ceramic brake disc comprises the following raw materials in percentage by weight: 1 to 4 percent of phenolic resin, 1 to 5 percent of boron modified phenolic resin, 4 to 15 percent of aluminum metaphosphate, 3 to 7 percent of sodium silicate, 1 to 3 percent of ammonium fluoride, 1 to 5 percent of magnesium oxide, 3 to 5 percent of copper oxide, 2 to 6 percent of aluminum powder, 1 to 6 percent of carbon fiber, 1 to 6 percent of aramid pulp, 8 to 15 percent of steel fiber, 15 to 25 percent of reduced iron powder, 6 to 12 percent of red copper powder, 1 to 3 percent of antimony oxide, 5 to 8 percent of zinc borate, 2 to 6 percent of antimony trisulfide, 4 to 6 percent of molybdenum disulfide, 5 to 8 percent of calcined petroleum coke, 1 to 5 percent of aluminum titanate, 1 to 4 percent of titanium oxide, 5 to 12 percent of zirconium oxide, 4 to 8 percent of silicon carbide and 2 to 6 percent of chromium trioxide.
The brake material prepared by adopting the components in proportion is an organic ceramic composite material, wherein the resin comprises two types of phenolic resin and boron modified phenolic resin, the decomposition temperatures of the two types of resin are different, and the two types of resin are matched for use to promote each other, so that the high-temperature heat fading phenomenon is reduced, and the production difficulty is greatly reduced; inorganic binder composed of aluminum metaphosphate and sodium silicate and components thereof are molded in three stages of heat curing at 100-200 ℃,200-350 ℃ and 350-500 ℃, titanium oxide dispersing agent changes surface tension and electronegativity of mixed fiber to prevent flocculation, ammonium fluoride and magnesium oxide are used for curing and molding aluminum metaphosphate at 100-200 ℃ by using curing agent, and curing is continuously completed at subsequent high temperature, so that curing time is shortened. Aluminum metaphosphate and sodium silicate are ceramic inorganic adhesive and are solidified into ceramic continuous phase matrix at high temperature, so that the high temperature resistance and wear resistance of the brake pad are enhanced. Carbon fiber and aramid fiber are mainly reinforcing matrix phases with high temperature and high modulus, steel fiber is mainly reinforcing phase, and meanwhile, the composite friction material is also a good friction increasing material, and the composite friction material can improve the heat conducting performance of the brake pad and reduce the decline of friction coefficient at high speed by being matched with reduced iron powder. Copper powder is a good lubricant and reduces the vibration during braking and reduces wear. Silicon carbide mainly plays a role in increasing the high-temperature friction coefficient. The calcination of the petroleum coke helps to reduce noise, reduce damage to the disc, and reduce wear. Antimony sulfide is lubricated at high temperature, zirconium oxide and an inorganic binder form a ceramic phase and increase the friction coefficient. Zinc borate and antimony oxide are flame retardant materials, and can inhibit the ignition and combustion of the high-temperature decomposition products of the resin to a certain extent. Through the reasonable proportioning design of the materials, perfect matching with the carbon ceramic disc is realized, and the brake effect is good.
