Beneficial effect of the present invention is:
The present invention uses new component formula processing abrasive material, brake rim is made to have stable friction factor, high temperature friction performance is good, friction noise is low, heat fade is little, the advantage that wear rate is low, specifically by rational allocation oiling agent, lapping paste, the proportioning of reinforcing fiber and filler, the friction factor of brake rim rubbing surface is controlled 0.35 ~ 0.38 stablize in moderate scope, abrasive material is made to reach rational rates of thermal expansion, porosity and cold, thermal pressure simulation amount, realize (mating material S355 J2G3) low wear rate 0.2 ~ 0.4(V when operating temperature 150 DEG C)/[10 7cm3/ (N.m)], the good result of low noise < 55dB (A), and maximum noise > 130dB (A) before improving, and make obtained brake rim be more suitable for low speed, low temperature is dawdled braking, steel mating material.
The present invention is by processing technology, and accelerate reaction process, improve the porosity of abrasive material, under preventing high temperature, organic substance produces lubricating film at friction surface, thus improves stable friction factor.Heat treatment temperature 210 DEG C during production, time controling is 120 minutes, and the lower-molecular substance of product organic component inherence is decomposed or volatilization, thus brake rim hardness is minimized, obtain good brake contact face, improve the braking sensitivity of brake rim, reduce the generation of friction noise; Through steel backing, respectively bury a wearing and tearing alarming line in inside, abrasive material two ends underground, when may wear to after alarming line buries aspect underground, the wearing and tearing warning circuit of control end will conducting, and produce alarm signal, brake rim is changed in prompting; There is chamfering front end and back end at its running orbit on the rubbing surface of brake rim, and vibration and the rear end corner angle that can reduce front end corner angle extruding initiation are torn, fallen block; Brake rim and the fricative gas of brake disc and carbide abrasive dust can be discharged by parabolic wire casing, reduce the adhesion of carbide abrasive dust between brake rim and brake disc face, reduce friction noise.
Below by the ingredient properties analyzing abrasive material main material, beneficial effect of the present invention is described:
(1) PTS suspension method phenolic resin, there is excellent resistance to heat and mechanical property, electrical insulating property and moulding processability good, decomposition temperature reaches 490 DEG C, with this resin for the brake rim that binder is made has the advantages such as stable friction factor, high temperature friction performance is good, noise is low, heat fade is little.And using pure phenolic resin that brake rim much higher hard, fragility can be caused large, heat-resistant limit temperature is only about 250 DEG C.
(2) graphite and tin sulfide or copper sulphide etc. are as oiling agent, and when can reduce to brake, the change of friction factor, optimizes friction factor and wear rate.
(3) antimonous sulfide, zirconium silicate, silicon carbide, silica etc. are as lapping paste, the friction factor of friction material can be increased, the skin covering of the surface having adverse effect produced when the ferriferous oxide on removable mating material and braking, but the lapping paste of high-load can increase the wave properties of friction factor, therefore need its adding quantity to control in the reasonable scope.
(4) reinforcing fiber such as ceramic fiber, aramid fibre, carbon fiber, Steel Fibre, copper fiber and potassium titanate crystal whisker effectively can improve frictional behaviour.The Properties of Friction Materials that Single Fiber strengthens is not comprehensive, there is various defect, and several fibers mixture together, and performance can be complementary, plays confounding effect, and the Properties of Friction Materials of preparation is excellent.Together with potassium titanate crystal whisker is attached on aramid fibre, can improve heat resistance and the intensity of friction surface film, potassium titanate fibre makes stable friction factor, heat resistanceheat resistant decline performance and wearability improve; The friction factor of copper fiber and Steel Fibre brake rim all reduces along with the increase of Sliding velocity, adds copper fiber and friction material can be made to have high and stable friction factor and very low wear rate, reduction compressibility; Aramid fibre can overcome the heat sensitivity of resin, promotes stable friction factor, reduces wear rate; Carbon fiber makes friction material have good heat resistanceheat resistant decline performance.
(5) mineral filler such as calcium carbonate, mica, vermiculite and foam ferrous powder, has material impact to the mechanical property of friction material, physical property and frictional behaviour, can regulate the hardness of friction material, improve friction noise and products appearance, reduce costs.Pearl filler, can improve the thermostability of friction material, also can improve the heat fade performance of material simultaneously.Mica and vermiculite filler, have plane reticular structure, can both suppress low frequency friction noise, but at high temperature wear-resisting property is very poor.Foam ferrous powder makes stable friction factor, comparatively light relative to its proportion of reducing iron powder, and its porous structure is conducive to reducing semimetal friction material goods friction noise in use.
(6) organic fill such as cashew nut shell oil Frication powder and rubber powder, has excellent viscoelasticity, is used in brake rim to reach the object reducing noise.
