Description
Technical field
The present invention relates to friction materials and preparation method thereof, in particular for method for preparing friction such as the stopper of motor vehicle brake-shoe, lathe and electrode, clutch facings.
Background technology
Automobile brake is commonly called as brake facing with friction materials, is one of most important safety component in the brake system of car, is concerning automobile driver's safety of life and property.The preparation of brake block is generally take resin, fortifying fibre, frictional property regulator and filler etc. as raw material, by after the even mixing through hot pressing, make after solidifying.For improving the braking ability of friction materials, fortifying fibre and frictional property regulator have obtained broad research, become present Study on Friction Materials focus.
Traditional brake facing mainly is wild phase with the fibrous magnesium silicate, after finding that asbestos are a kind of important carcinogenic substance, the semimetal friction material that with the steel fiber is wild phase has obtained fast development, be widely used at present the braking of various types of vehicles, but there is the shortcoming of easy-to-rust in semimetal friction material.For improving frictional behaviour, avoiding semimetal friction material to descend because of the braking ability that the steel fiber corrosion brings, slag fibre, aramid fiber, ceramic fiber, carbon fiber etc. are applied gradually.But the price of the aramid fiber of above-mentioned better performances, ceramic fiber, carbon fiber etc. is higher, causes the production cost of high-quality friction material sharply to rise thus.
For improving its friction and wear behavior on the basis that reduces the friction material production cost, frictional property regulator has obtained broad research, becomes one of important channel of improving Properties of Friction Materials.Frictional property regulator is that a class is added the material that can improve coefficient of friction and wear rate in the friction material to, mainly is divided into lubricant and grinding agent two big classes.The main purpose of lubricant is the variation of frictional coefficient when reducing to brake, and lubricant commonly used comprises graphite and various types of metallic sulfide; Abrasive mainly is the hard particles of metal oxide, silica powder and silicate compound, and abrasive commonly used mainly contains aluminum oxide, silicon carbide, silicon-dioxide, Zirconium oxide, zirconium silicate and chromated oxide etc.(2007,40 (7): discovering 1161-1169), the interpolation aluminum oxide can improve frictional coefficient, reduce wear rate people such as Boz M in friction materials at Tribology International.People such as MatejkaV are published in studies show that on the Wear magazine, add silicon carbide in friction materials, can increase substantially frictional coefficient and wear rate has only a small amount of increase; People such as Jang H are published in Wear, and (2000,239 (2): discovering 229-236), a certain amount of antimony trisulfide and zirconium silicate powder all exist bigger influence to size, the stability of automobile brake sheet frictional coefficient.Yet the at present research for frictional property regulator mainly concentrates in the selection of different materials, for the same material system and the research of different hardness and different-grain diameter powder and commercial application report seldom.Designer of the present invention found through experiments, and the powder that thick ceramic powder particle and particle diameter are tiny is compared, and has better to increase the performance of rubbing.
