Description
Technical field
The present invention relates to field of compound material, particularly a kind of automobile brake sheet friction materials.
Background technology
Along with the fast development of automotive industry, automobile pollution is also in continuous expansion.Automobile brake sheet, as the key part of brake system of car, need meet brake safe reliable, and noiseless requirement operates steadily.Current domestic automotive friction material type can be divided into three kinds: 1) asbestos base: its low cost of manufacture, and technique is simple; Be mainly used in agricultural vehicle and engineering machinery.The shortcoming of its existence: asbestos are harmful, contaminate environment, high temperature heat fading is serious, poor stop, safety coefficient is little, and this kind of product reducing year by year, belongs to obsolete product.2) semi-metallic based: have good temperature tolerance and resistance to decline performance at high temperature, manufacturing cost is moderate; Domestic application is more extensive.The shortcoming of its existence: the hardness of product is high, have noise during braking, particularly low speed braking or morning effect easily produce noise, product surface easily gets rusty, corrode mating plate simultaneously, thermal conductivity is high, when friction temperature is during higher than 300 ℃, easily makes the tackiness agent between friction materials and steel disc decompose, high friction heat is transmitted to rapidly stopper hydraulic gear on the other hand, causes the aging and braking fluid generation vapour lock of hydraulic pressure " O " RunddichtringO and causes brake fade.3) few metal matrix: advantage is less to coiling bulging aggressiveness, and noise is little, wears away relatively semi-metallic based little; On car, use more.The shortcoming existing: noise and the grey problem that falls still do not solve, easy-to-rust.The development trend of external automotive friction material is take ceramic base as main, ceramic-based friction material is invented by 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 applicable to very much the brake request of high-performance passenger car.Ceramic-based friction material has occupied the whole world two large Main Auto market---the more than 60% of North America and Japanese market at present.
But domestic ceramic-based friction material brake facing is also immature, and its product performance can't meet user demand.
Summary of the invention
For the deficiencies in the prior art, one of object of the present invention is to provide a kind of automobile brake sheet friction materials.
For achieving the above object, the technical solution used in the present invention is as follows:
A kind of automobile brake sheet friction materials, this friction materials is comprised 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, barium sulfate 8-10 part, colloid molybdenumdisulphide 2-4 part, talcum 3-5 part, flake graphite 8-10 part.
In the present invention, said thermosetting resin can be one or more in resol, boron modified phenolic resin, melamine modified phenolic resin and aralkyl modified phenolic resins.
Said resin curing agent can be one or more in hexamethylenetetramine, sulphur and urotropine.
Preferably, this friction materials is comprised 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, barium sulfate, 3 parts of colloid molybdenumdisulphide, 4 parts, talcum, 9 parts of flake graphites.
Friction materials of the present invention can adopt the method preparation of conventional batching, batch mixing, moulding, hot pressing, during preferred batch mixing, powdered material, colloid molybdenumdisulphide, graphite are mixed respectively, join again in the system of resin, resin curing agent, sapphire whisker and the mixing of aluminium titanates whisker, prepare mixed friction material.
The present invention has following beneficial effect:
Optimized choice of the present invention the material of friction component and lubricant component, the combination of material ceramic powder, fiber and whisker is as friction group member, and on the basis of great many of experiments, 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 coordinative role effect at friction materials on period, reasonably allocate frictional coefficient, it is stablized suitable, reduced again wearing and tearing, and stable working, noiselessness.Heat conduction efficiency is good, and braking quality is stable, safe and reliable.Utilize the distinctive wear-resistant property of stupalith, stablizing on the basis of friction materials frictional coefficient, effectively reduce its wear rate, thereby improve the work-ing life of friction materials.
