Description

The ceramic automobile brake block and its production method of a kind of environment-friendly high-efficiency
Technical field
The present invention relates to automobile brake technical field, the particularly a kind of ceramic automobile brake block of environment-friendly high-efficiency and its production Method.
Background technology
It is well known that automobile brake sheet is the important key components and parts of automobile normal safe operation, existing braking automobile Piece mainly have frictional layer, steel back, bloop, alarm card by produce and process with being assembled, its frictional layer because material difference and It is divided into asbestos brake lining, powder metallurgy brake flat and semi-metallic brake pad, asbestos brake lining wear-resisting property is poor, and asbestos are high in addition Carcinogen, environment easy to pollute, is gradually eliminated in recent years.Metal brake block and semi-metallic brake pad heat endurance are poor, are rubbing When producing higher temperature, their frictional force decline, and directly affect braking ability, also have metal and semi-metallic brake pad hardness compared with Height, can cause mating material brake mill damage big, brake disc marked groove mark (groove), and when brake produces ear-piercing metal abnormal sound, Both environment is influenced, also influences the comfort of driver and passenger.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide one kind is beneficial to environmental protection, heat endurance is high, rubs Wipe reliable coefficient stabilization, braking ability, the ceramic brake of environment-friendly high-efficiency and its production method.The purpose of the present invention passes through following Technical solution is realized.A kind of ceramic brake of environment-friendly high-efficiency, including frictional layer, steel back, bloop, alarm card and fluting, It is characterized in that:Frictional layer is formulated by weight by following component:Aramid fiber 7-8, ceramic fibre 5-8,98% copper Fiber 5-6, potassium titanate crystal whisker 1-2, calcium carbonate crystal whisker 23.2-33.5, aluminium oxide 5-7, antimony trisulfide 1-1.9,40 height of eye carbon graphites 1.5-1.7, calcined petroleum coke 7.3-21.3, nitrile rubber powder 2-2.8, vermiculite 1.6-3, Frication powder 5.7-15.7, blanc fixe 4.2-4.75, fine particle calcium carbonate 22,2-37.5, phenolic resin 5.
A kind of production method of the ceramic brake of environment-friendly high-efficiency follows these steps to carry out:1st, weigh, by above-mentioned frictional layer The above-mentioned each component of weight ratio precise of each component is spare;2nd, mix, load weighted each component is uniformly mixed spare; 3rd, it is die-filling, uniformly mixed powder is accurately measured according to the weight demands of brake block and is inserted in frictional layer mould;It is 4th, compressing, Mould equipped with mixed powder is inserted in the hot press of 300 tons of pressing pressures, 170 degree of hot pressing 3 minutes, takes out spare;5th, dry It is roasting, by the frictional layer blank suppressed be placed in baking oven 200 degree toast 4 it is small when;Frictional layer after baking is slotted, is ground Flat, chamfering is simultaneously fixedly connected integrally with steel back, alarm card, bloop by rivet, then row spray painting coding, test package enter Storehouse.
After testing, all technical meets national standard to product of the present invention, and design parameter is as follows:Friction coefficient b (μ) 0.35-0.5, wear rate (V)/[10-7cm/ (N.M)] shear strength are not less than 2.5Mpn.400 degree of coefficient of thermal expansion, 10 degree of scholar is little In 2.5%, compression strain at room temperature when be not more than 2%, 400 DEG C of whens, are not more than 5%.
Compared with traditional brake block, the invention has the advantages that:
(1)Conventional brake piece frictional layer is metal or the frictional layer of asbestos material production, and brake force is big, but wears greatly, and Easily there is noise.Since ceramic brake is free of above-mentioned material, just thoroughly solve brake block with during brake disc phase mutual friction Metal device is called;
(2)With stable friction coefficient, friction coefficient is the most important performance indicator of friction material, is related to brake block braking The quality of performance, in brake process, since friction generates heat, operating temperature increases, general brake block friction material It is influenced by temperature, friction coefficient is begun to decline.Frictional force can be reduced in actual application, so as to reduce braking action. Common brake block friction material is immature, and friction coefficient is too high to be caused direction out of control in braking procedure, burns piece, scratch brake disc etc. Insecurity.Even if the temperature of ceramic brake brake disc is up to 650 DEG C, the friction coefficient of ceramic brake still exists 0.45-0.55 or so, can guarantee that safely vehicle has good braking quality and safe normal operation;
(3)Ceramics have preferable heat endurance and relatively low pyroconductivity, good wearability, and long-time service temperature exists 1000 degree, this characteristic makes ceramics to be adapted to the high performance requirements of various high-performance brake materials, can meet brake block high speed, peace The technical requirements such as Quan Hua, high abrasion;
(4)With good mechanical strength and physical property, there are larger pressure and shearing force.To ensure processing or using Damaged and fragmentation phenomenon is occurred without in journey;
(5)There is very low heat fade.Still it can guarantee that with good braking quality, to ensure safe normal operation, and stop The phenomenon very little of car piece heat fade;
(6)Lifting brake piece performance, because of the reason of the rapid heat dissipation of ceramic material, in the manufacture of brake, its friction coefficient The 30% of other brake block friction coefficient will be higher than;
(7)Excellent material characteristic, 40 height of eye carbon graphites of ceramic brake use, brass, advanced ceramic(Non-asbestos)With half The hitech materials such as metal have high temperature resistant, wear-resisting, brake stabilization, do not hinder brake disc, environmental protection, noiseless, service life length etc. Advantage, overcomes the material of conventional brake piece and technologic defect, is most advanced advanced ceramic brake block in the world at present. In addition thereto, ceramic shot content is low, and enhancement is good, can also reduce antithesis abrasion and the noise of brake block, improve and drive people The comfort of member and the quality and service life of product, in turn ensure that automotive safety normal operation.
