Description
Technical field
The present invention relates to a kind of friction plate, relate in particular to the friction plate that uses on a kind of little car or the tricycle braking device, the invention still further relates to the preparation method of this kind friction plate.
Background technique
In little car and tricycle industry, friction plate belongs to one of critical material, and its quality not only affects rideability, and is concerning driver and passenger's life safety.Therefore require used friction plate material must possess good heat resistanceheat resistant decline performance, frictional behaviour is good, and wear rate is low, require that effect is sensitive, shockproof during braking, noise free, do not hinder mating plate.
Traditional friction plate adopts asbestos as reinforcing material, and the ratio of weight and number of each component in its prescription is: 9 parts of resins, 40 parts in asbestos, 1 part of nitrile rubber powder, 6 parts of tyre talcs, 6 parts of vermiculite powers, cotton 6 parts of silicon, 10 parts in barium sulphate, 8 parts of antimony sulphides, 2.5 parts of iron oxide yellows, 1 part in aluminium oxide, 2.5 parts in friction powder, 2 parts of calcined coke powdered carbons, 2 parts on mica, 2 parts of cellulose fibers.Asbestos are as the main component in this prescription, in the recent period owing to be subject to the impact that natural condition change, the hydraulic performance decline of asbestos deposit, friction factor is low, and friction factor is unstable under the high temperature, and wear rate is large, thereby so that the working life of braking plate is not long, brake failure is quick, and is unreliable.And its highly corrosion resistant causes great impact to environment, and especially after asbestos were confirmed as carcinogenic substance by medical circle, it also was restricted in application facet.Therefore seek and new accomplish without asbestos, under the principle of Cost reduction that material softly, low is polluted, the prescription of the friction plate of low abrasion and higher utilization rate becomes the new problem of pursuing in the present industry.
Summary of the invention
Purpose of the present invention just is to provide a kind of low cost, the low friction plate that pollutes, hangs down abrasion, and the present invention also provides the preparation method of this kind friction plate.
