Description
Technical field
The present invention relates to friction material fields, more particularly, to a kind of automobile friction material and preparation method.
Background technique
The effects of friction material is for playing transmission, braking, deceleration, steering, parking in many movable machineries and equipment
Functional accessory, it may be said that since having mechanical movement, the mankind just have the requirement of brake, and wooden unit, ox-hide, rubber etc. were all once
Through being used as brake material.Asbestos friction material is as traditional product always by people before the 1970s and 1980s in last century
Class largely uses, after this, since known widely asbestos can cause pulmonary lesion and ask rind gall and related with the generation of lung cancer.1972
Year international medical oncology discussion confirmation asbestos fibre contains carcinogen, hereafter, friction goods without asbestos and pollution-free
Change the common recognition for being increasingly becoming world's sexual development.No. 13 regulation of United Nations Economic Commission for Europe (ECE) and international standard committee
In the related standard of member's meeting (ISO), explicit stipulation is forbidden producing and selling and using asbestos product.International Maritime Organization
" for all ships, the novel installation containing asbestos material should be forbidden 2000 amendment clear stipulaties of 1974S0LAS pact, remove
It is non-to have particular/special requirement." State Bureau of Technical Supervision provides in mandatory national standards GB12676-1999, " from 2003 10
From the moon 1, brake lining should not contain asbestos ".
In existing asbestos-free friction material technology, there are many alternative materials as asbestos fibre reinforcing material, metal
Fiber, carbon fiber, glass fibre, ceramic fibre and aramid fiber are all the friction members such as all kinds of brakes of manufacture, clutch facing
Ideal reinforcing material in the raw material of part, characteristic and price and mutual proportion are largely fixed
The performance and application prospect of friction element.Friction material mainly consists of three parts:1, adhesive;2, reinforcing fiber；3
, frictional property regulator.The selection of various formulas and composition material must be carried out according to target to be achieved, and is selected
Select suitable manufacturing method and production technology.
Currently, automobile brake friction plate largely uses two antimony of curing, for profit of the friction material in high temperature friction
It is sliding, it is ensured that the stabilization of high temperature friction coefficient.Antimony trisulfide is to be obtained by brightness Jin Kuang by selected and chemical purification, is black solid powder
End.Its fusing point is relatively low, is 548 0C, the antimony oxide generated after pyrolytic, and the gold generated in the presence of reducing agent
Belonging to antimony, the oxidizing fire of material, keeps the stable friction factor of material, improves the ability of anti-burning of material when can prevent high temperature,
Organic bond decomposition rate at high temperature can also be reduced, improve the service life of material, play high temperature inorganic adhesive and
The effect of lubrication friction regulator.But antimony is heavy metal element, after entering in air, rainwater and soil with friction dust not
It is degradable, directly or indirectly to human body, heavy metal poisoning can be caused to health of people, destroy human body interior circulatory and respiratory road and
Digest road junction therefore, EC regulations require to gradually reduce the dosage of the antimonous sulfide in friction material, at the latest in 2020
Thoroughly forbid the addition in friction material.Obviously, prior art automobile brake friction plate there is contain heavy metal antimony, it is right
Environment pollutes, and causes harm to the human body, i.e., by disabled the problems such as using in automobile brake friction plate.
