Abstract
The invention discloses a dual-whisker-compounding-reinforced resin-based lining of an automobile brake. The dual-whisker-compounding-reinforced resin-based lining comprises, by weight, 14% to 16% of calcium carbonate whiskers, 2% to 3% of potassium hexatitanate whiskers, 12% to 14% of phenolic resin, 2% to 4% of carboxy powdered butadiene-acrylonitrile rubber, 8% to 12% of graphite, 15% to 25% of friction performance conditioning agents and 30% to 40% of packing. According to the dual-whisker-compounding-reinforced resin-based lining, common powdered acrylonitrile-butadiene rubber is replaced by the carboxy powdered butadiene-acrylonitrile rubber, the molecular polarity of the butadiene-acrylonitrile rubber is improved, the compatibility of the phenolic resin is improved, product performance is improved, the manufactured friction materials have the advantages of being stable in friction coefficient, small in thermal decay, low in abrasion and free of damage to a mating plate, and performance and economical efficiency are considered at the same time.
Description
Technical field
What the present invention relates to is a kind of automotive brake liner, and in particular a kind of twin crystal must composite strengthening resin base automotive brake liner.
Background technique
Brake block, as the key element of brake system of car, has the use history of over one hundred year.At present, the gross production of car has occupied the more than 35% of China's automobile gross production, because car is generally front wheel driving design, front-wheel adopts disc type brake, trailing wheel adopts drum brake, main product in drum-type brake pad Ye Shi China friction material goods thus, Drum brake linings also needs good braking ability, not only require that it is high temperature resistant, stable friction performance, noise free, atremia, be difficult for rubbing and hinder mating plate, meet short distance inside brake, long service life, but also to have pollution-free, brake the features such as comfortable.Asbestos, were once the certain materials in automobile brake sheet, but because it loses and strengthen the property in high temperature time dehydration, its dust easily allows people obtain lung cancer, does not meet environmental requirement, thereby cannot meet the needs of Hyundai Motor.At present, the asbestos-free friction material (NAO type friction material) of external friction material industry research and development is comparatively ripe, but China is just in the infancy.Therefore seek asbestos alternative that cost performance is high and become the urgent problem of domestic brake block industry.External lot of documents has been studied the application of mixing, silicon carbide whisker, carbon whisker and the potassium titanate crystal whisker etc. of the mixing, sepiolite fibre, inorfil and the organic crystalline palpus that adopt long and short fiber, replace poisonous asbestos, further improve the braking effect of brake facing, but because these whiskers are expensive, need to find material of high quality and at a reasonable price and replace it.And the appearance of calcium carbonate crystal whisker, it can make the mechanical property of composite material be improved, and more makes the development of friction material enter the world that a slice is new.
Calcium carbonate crystal whisker diameter is 0.5～1.0 μ m, length 20～30 μ m, belong to environment protection type functional material, have good mechanics and physical property, stable friction performance, wear resistance, good heat resistance, product can improve 30% working life, is one of ideal substitute of asbestos.First calcium carbonate crystal whisker is carrying out industrialization in Japan, compared with the whisker such as SiC, potassium titanate in existing market, because the loading of calcium carbonate crystal whisker is large, production technology is simple and cost is lower, thereby provide wide application prospect in the extensive application in the fields such as friction material for whisker.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of twin crystal palpus composite strengthening resin base automotive brake liner is provided, adopt twin crystal must improve the performance of liner
The present invention is achieved by the following technical solutions, the present invention by weight, comprise calcium carbonate crystal whisker 14～16%, crystal whisker of hexa potassium titanate 2～3%, phenolic resin 12～14%, carboxyl PNBR 2～4%, graphite 8～12%, frictional property regulator 15～25%, filler 30～40%.
Described frictional property regulator comprises one or more the mixture in friction powder, zirconium silicate, expanded vermiculite, sulphide and oxide.
Described filler is selected from one or more the mixture in blanc fixe, diatomite, fluorite and white clay.
The present invention has the following advantages compared to existing technology: the present invention adopts carboxyl PNBR to substitute conventional PNBR, improve the molecular polarity of nitrile butadiene rubber, increase the compatibility of its phenolic resin, product performance are improved, the friction material making has stable friction factor, heat fade is little, the feature little, that do not damage antithesis of wearing and tearing, and has taken into account performance and Economy.
