Description
Technical field
The present invention relates to field of compound material, particularly a kind of automobile brake sheet is used friction materials.
Background technology
Along with the fast development of automotive industry, automobile pollution is also in continuous expansion.Automobile brake sheet is as the key part of brake system of car, and it is reliable to satisfy brake safe, and noiseless requirement operates steadily.Present domestic automotive friction material type can be divided into three kinds: 1) asbestos base: its low cost of manufacture, and technology is simple; Be mainly used in agricultural vehicle and engineering machinery.The shortcoming of its existence: asbestos are harmful, contaminate environment, and the elevated temperature heat decline is serious, poor stop, SF is little, and this kind product is reducing year by year, belongs to obsolete product.2) semi-metallic based: have good temperature tolerance and at high temperature anti-decline performance, manufacturing cost is moderate; Domestic application is more extensive.The shortcoming of its existence: noise, particularly low speed braking or the easy noise that produces of effect in morning are arranged when the hardness height of product, braking, and product surface is prone to get rusty; Corrode mating plate simultaneously; Thermal conductivity is high, when friction temperature is higher than 300 ℃, is prone to make the tackiness agent between friction materials and steel disc to decompose; High friction heat is transmitted to the stopper hydraulic gear rapidly on the other hand, causes hydraulic pressure " O " RunddichtringO to wear out and causes brake fade with braking fluid generation vapour lock.3) few metal-based: advantage is bulging aggressive less to coiling, and noise is little, wears and tears semi-metallic based relatively little; On car, use more.The shortcoming that exists: noise does not still solve easy-to-rust with the grey problem that falls.The development trend of external automotive friction material is to be main with ceramic base; Ceramic-based friction material is by the invention of Japanese friction materials enterprise; Advantage is that high temperature heat-resistant fails, wear resisting property is excellent, heat-conduction coefficient is little, intensity is high, environmental protection, is fit to very much the brake request of high-performance passenger car.Ceramic-based friction material has occupied the whole world two big main automobile market---more than 60% of North America and Japanese market at present.
But that is that all right is ripe for domestic ceramic-based friction material brake facing, and its product performance can't satisfy user demand.
Summary of the invention
To the deficiency of prior art, one of the object of the invention is to provide a kind of automobile brake sheet to use friction materials.
For realizing above-mentioned purpose, the technical scheme that the present invention adopts is following:
A kind of automobile brake sheet is used friction materials, and this friction materials is made up of following component in weight part: thermosetting resin 23-27 part, resin curing agent 6-8 part; Sapphire whisker 10-12 part, potassium titanate crystal whisker 4-6 part, attapulgite 2-4 part; Chromite powder 5-7 part, Calucium Silicate powder ceramics powder 6-8 part, permanent white 8-10 part; Colloid molybdenumdisulphide 2-4 part, talcum 3-5 part, flake graphite 8-10 part.
Among the present invention, said thermosetting resin can be one or more in resol, boron modified phenolic resin, cyanurotriamide modified resol and the aralkyl modified resol.
Said resin curing agent can be one or more in hexamethylenetetramine, sulphur and the urotropine.
Preferably, this friction materials is made up of following component in weight part: 25 parts of thermosetting resins, 7 parts of resin curing agents; 11 parts of sapphire whiskers, 5 parts of potassium titanate crystal whiskers, 3 parts of attapulgites; 6 parts of chromite powders, 7 parts of Calucium Silicate powder ceramics powders, 9 parts in permanent white; 3 parts of colloid molybdenumdisulphide, 4 parts in talcum, 9 parts of flake graphites.
Friction materials of the present invention can adopt conventional batching, batch mixing, moulding, the preparation of hot pressed method; During preferred batch mixing powdered material, colloid molybdenumdisulphide, graphite are mixed respectively; Join in resin, resin curing agent, sapphire whisker and the aluminium titanates whisker blended system preparation mixed friction material again.
The present invention has following beneficial effect:
Optimized choice of the present invention the material of friction constituent element and lubricant component, the combination of material ceramic powder, fiber and whisker is as the friction group member, and on the bases of testing in a large number, reasonably selected the ratio of each component; Make sapphire whisker, potassium titanate crystal whisker, attapulgite; Chromite powder and Calucium Silicate powder ceramics powder can play the coordinative role effect at the friction materials on period, promptly reasonably allocate frictional coefficient, make it stable suitable; Reduced wearing and tearing again, and stable working, noiselessness.Heat conduction efficiency is good, and braking quality is stable, and is safe and reliable.Utilize the distinctive wear-resistant property of stupalith, on the basis of stablizing the friction materials frictional coefficient, effectively reduce its wear rate, thereby improve the work-ing life of friction materials.
