Description
Technical field
The present invention relates to brake block technical field, be specifically related to a kind of automobile brake sheet using on automobile.
Background technique
Automobile brake sheet is early asbestos type brake block, but people find asbestos now, by medical circle, is confirmed it is carcinogen.Brake each time, brake block will be dispersed into the asbestos fiber more than millions of in air, and the spacing of its needle-like is easy to enter lung and stops, and causes stimulation, finally can cause the generation of lung cancer.But except the factor of health risk aspect, also there is another major issue in asbestos type brake block.Because asbestos are adiabatic, its capacity of heat transmission is poor especially, Reusability rear brake can make heat pile up in brake block, after brake block heating, its braking ability will change, producing same friction and braking force can need the number of times that more touches on the brake, if brake block reaches certain temperature, will cause brake failure.
Summary of the invention
The present invention is directed to the above-mentioned deficiency of prior art, the automobile brake sheet of a kind of nuisanceless, pollution-free, noise free, no-spark, wear-resisting, long service life is provided.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of automobile brake sheet, this automobile brake sheet comprises steel backing and is bonded in the friction material on steel backing, described friction material comprises that each component of following weight portion is prepared from: butyl butylbenzene 1-10 part, hydrogen phosphide cumene 0.5-2 part, epoxy resin 0.5-2 part, boron bakelite resin 1-15 part, polypropylene 1-15 part, nylon powder 6-10 part, boron nitride 5-10 part, coupling agent 0.01-0.05 part, dicumyl peroxide 1-5 part, Cosan 1-2 part, benzoic acid 1-2 part, stearic acid 1-2 part, boric acid 1-2 part, graphite 50-60 part, ceramic fiber 5-8 part, potassium titanate 0.5-1 part, reducing iron powder 1-2 part, barium sulphate 1-2 part, alum earth 0.5-2 part, feldspar powder 0.5-2 part, zine oxide 0.5-2 part, promoter 0.01-0.05 part, age resister 0.01-0.05 part, Fluorspar Powder 0.5-2 part, silicon carbide 0.5-2 part, coumarone 0.5-2 part.
Promoter of the present invention is as promoter TT, Urotropinum or captax.
Age resister of the present invention is that N-phenyl-2-naphthylamine is commonly called as antioxidant D.
Coupling agent of the present invention is silane coupling A-151.
Described graphite is chemically treated graphite, and concrete processing procedure is: graphite is joined in 98% the concentrated sulphuric scid, stirring reaction under vacuum condition, then slowly drips hydrogen peroxide, and to control reaction temperature be 30~40 ℃, reacts 25~30 minutes; Reacted rear centrifugation, gained solid is washed till neutrality with clear water, then in baking oven 80~100 ℃ dry 1 hour.
The preparation method of the above-mentioned automobile brake sheet of the present invention obtains according to conventional preparation method, and technique is: the mediate-mixing-compacting-sulfuration of raw material mixing-raw material, curing-reconditioning-finished product, and concrete technology is as follows:
(1) raw material mixes: according to formula rate, and first by graphite, alum earth, feldspar powder, Fluorspar Powder, silicon carbide mixes;
(2) raw material is mediated: in step (1) mixture, add the surplus stock of formula rate to mediate;
(3) mixing: the raw material after above-mentioned kneading is carried out mixing, temperature is 250-350 ℃, and the time is 10-50min;
(4) mixture after the kneading of step (3) gained is carried out in mould hot-forming, pilot pressure is 50-100MPa(500-1000kg/cm
2), hot pressing time 4~6 minutes;
(4) the compressing article of step (4) are vulcanized, temperature is 150-200 ℃, 0.3~0.5MPa(3-4kg/cm
2);
(5) then reconditioning obtains finished product and steel backing bonding.
Advantage of the present invention and beneficial effect:
1. the present invention adopts and adds graphite to replace traditional asbestos.Graphite, has heat-conductive characteristic good, braking when (retro-speed 200km/h) temperature rise low, below general 200 degree, the not cooling continuous brake temperature of high temperature is no more than 300 degree; Can there is good compatibility with other components, thereby effectively guarantee the performance of friction material integral body; Graphite also has the functions such as withstand voltage, pliability and self lubricity in addition.The friction material of automobile brake sheet of the present invention also comprises the materials such as ceramic fiber, potassium titanate, and ceramic fiber is a kind of fibrous light refractory material, has lightweight, high temperature resistant, good thermal stability, heat conductivity is low, specific heat is little and the advantage such as resistance to mechanical shock; Potassium titanate can slow down energy in brake process toward the transmission of brake block the inside, the rising of temperature is slowed down, thereby played wear-resisting effect, potassium titanate causes coefficient low, and stable, energy transmission in the brake process that slowed down, also play wear-resisting effect, the high temperature sound absorption of potassium titanate, has partially absorbed the noise that friction material produces in brake process, has reduced noise pollution.The friction material of automobile brake sheet of the present invention is by the choose reasonable of each component kind and the choose reasonable of each constituent content, makes brake block of the present invention have the advantages such as, noise free very friendly, nuisanceless, pollution-free to environment, no-spark, wear-resisting, good thermal stability, long service life.
2. the friction material of automobile brake sheet of the present invention is not used asbestos, so automobile brake sheet of the present invention can not discharge and poisonously have the asbestos fiber of pollution in air; In the friction material of automobile brake sheet of the present invention, do not contain heavy metal substance, and heavy metal substance has a small amount of heavy metal dusts in brake process at every turn, discharge and be accumulated in environment and work the mischief.So automobile brake sheet of the present invention be a kind of nuisanceless, pollution-free, use, meet sanitary brake block safely.
3. automobile brake sheet long service life of the present invention, according to the high braking force 40KN of UIC-541-3VE, high-temperature brake (retro-speed 200km/h) abrasion loss is 0.9cm
3/ MJ.
