The present invention features that the brake block is made with nanometer modified resin, composite mineral fiber, organic fiber, mineral fiber, ceramic fiber, artificial graphite, baritite and other materials in certain weight proportion, and through mixing, hot pressing and heat treatment. The brake block has the advantages of no pollution, good damping and noise reducing performance, low cost, long service life, high braking stability, etc.
Description
Technical field
The invention belongs to the brake system of car technical field, be specifically related to a kind of brake block of environment friendly composite material and manufacturing process thereof.
Background technology
Current technology, automobile have become one of human land visitor, the defeated modernized instrument that can not be substituted of shipping, and along with the development of China's economic society, automobile pollution is increasing substantially year by year, reaches 3,300 ten thousand in 2005.Can foretell that automotive industry will be one of mainstay industry of Chinese national economy in the long duration from now on.
But automobile is when bringing modern civilization happiness to the mankind, and the mankind are also bearing the harm that it brings.Its harm mainly shows three aspects: the one, and exhaust emission; The 2nd, noise pollution; The 3rd, the frictional wear dust pollution.Noise pollution has become the big public hazards in the modern city life.According to statistics, 75% from communications and transportation in the city noise, and wherein car noise accounts for 85%, and during automobile brake scream and chatter sound is the major portion of car noise.The dust that the brake wearing and tearing are produced in the Motor Vehicle Braking Procedure also is important source of pollution of modern city.Traditional brake facing all is to use fibrous magnesium silicate to strengthen.Asbestos are a kind of natural mineral fibers, and characteristics such as it has light weight, cheap, good dispersity, friction and wear behavior is good, reinforced effects is good once were widely used.But, international tumour medical science discussion in 1972 is confirmed, the fibrous magnesium silicate of having used in the asbestos brake lining in a nearly century belongs to the carcinogenic substance that influences HUMAN HEALTH, after tiny fibrous magnesium silicate in the braking dust is inhaled in the lung, can cause a kind of disease that is called asbestosis, even can cause lung cancer, asbestos are put into one of ten big noxious industry raw materials.Various countries have launched the development work of asbestos-free brake facing immediately rapidly, great amount of manpower and material resources and financial resources have been dropped into, Bendix company as the U.S. once invests 2500 dollars, one times of increase equipment, and researchist 60% specializes in the research of asbestos-free friction material.From the domestic and international patent analyses of delivering in recent years, the patent of non-asbestos brake block accounts for more than 90% of automobile brake sheet patent sum.
And find that in research and in using still there have been some problems to some extent in the brake facing of development and Application at present, though if any the brake facing performance improved, but complex manufacturing, cost has increased, and energy consumption has increased, and particularly brake noise and pollution aspect are also not very good.Therefore up to now, people also do not find a kind of asbestos that replace fully, satisfy the low noise braking brake block that over-all properties requires simultaneously again.Breaking system is one of vitals of automobile, speed, security, comfortableness and energy consumption that can the remarkably influenced running car, particularly vibratory noise pollutes, and has fundamentally limited the high speed and the heavy loading development of automobile, has become one of important factor of restriction automobile industry development.In the 21st century that environmental requirement becomes increasingly conspicuous, this situation of automobile brake sheet will become one of important factor of restriction Domestic Automotive Industry development.
In the past in a very long time, steel fiber enhanced semi-metallic brake pad is the emphasis that the scientific research personnel studies always, this brake facing is invented the earliest and is applied on the automotive disc brake by U.S. Bendix company, though it has stable frictional behaviour under normal temperature and high temperature, wear resistance is good, higher braking efficiency and thermal diffusivity are preferably arranged, but the density of steel fiber is relatively large, and easy-to-rust, easily sticking together after the corrosion influences the gear shift of automobile separation, and aggravation is worn and torn and the damage antithesis, and easily produces the low frequency noise of 100-300 hertz, follows deficiencies such as acutely shaking of car body simultaneously.
Summary of the invention
The objective of the invention is to design a kind of do not have asbestos, no steel fiber enhanced, friction and wear behavior is good, noise is low environment-friendly type brake facing matrix material, be used to manufacture brake facing.
Another object of the present invention is a kind of technology of using this kind material to produce brake facing of design.
For achieving the above object, main technical schemes of the present invention is the following material of environment-friendly type brake facing composite material by adopting (by weight percentage): nano modification resin 8-15, compound mineral fiber 13-25, organic fibre (GN1) 5-8, mineral fibre (NACF) 1-5, ceramic fiber 3-8, synthetic graphite 4-10, barite 7-10, diatomite 2-10, chromite powder 2-6, potassium felspar sand 2-5, zircon 1-3, antimony sulfide 2-5, expanded vermiculite powder 2-6, iron black 1-5, aluminium powder 2-6, mica 2-6, coke powder 1-3, butyronitrile rubber powder 2-5, tyre talc 3-6, zeolite 1-3.
Manufacturing process is:
One, above-mentioned material is mixed in proportion.
Two, the material that mixes is gone into hot pressing in the pressing mold of vulcanizer, 150 ℃-220 ℃ of its hot pressing temperatures, pressure 15-20Mpa, is pressed into brake facing at 10-20 minute heat-insulation pressure keeping time.
Three, brake facing is gone into electric oven and heat-treat, thermal treatment temp: slowly be warming up to 180 ℃-230 ℃ in (in 2-5 hour), be incubated 4-10 hour.
The brake facing that adopts such scheme to make does not contain fibrous magnesium silicate owing in its material, can reach pollution-free, has solved brake pad material to the harm that human body causes, and has good environment protecting; Because making the material of brake facing is no steel fiber enhanced, can effectively reduce noise and braking appearance " hot gas resistance " phenomenon; Therefore this kind brake facing has the favorable damping anti-acoustic capability, and environment protection is significant.At present China's motor vehicles for civilian use recoverable amount is 3,300 ten thousand, year consumes 330,000 tons of friction materialss, and car is with the about 0.8-1Kg of the every cover of brake facing (8), market price 80-100, and production cost 30-40 unit, per kilogram can be made a profit and be moistened about 60 yuan, and profit per ton is moistened 60,000 yuan.Therefore economic benefit is considerable.The brake facing of excellent property can make automobile to " at a high speed, heavy duty ", " lower performance, low public hazards " direction fast development, further improves driving safety, weather resistance, riding comfort and the operation convenience of automobile.Employed various material components are pollution-free, nuisanceless material in the brake block of environment friendly composite material prescription, and the brake facing finished product satisfies the low noise requirement.Therefore the popularization of this environment-friendly composite material brake facing production technology will have active effect to environment protection.
Compared with prior art, have pollution-freely, the vibration and noise reducing performance is good, can save material, and is cheap, long service life, advantage such as insensitivity is good.
