Abstract
A ceramic brake pad without asbestos and metals and a production process thereof relate to the technical field of brake pad processing. The ceramic brake pad without asbestos and metal includes a steel backing and a friction material, wherein the friction material consists of a aramid fiber, BaSO4, fibers, Al(OH)2, a crystalline flake graphite, a cashew nut shell liquid frictional powder and coal coke. The production process includes weighing raw materials, mixing the raw materials, performing compression moulding, processing the steel backing, compacting by a pressing machine, post-processing and installing accessories to produce a finished brake pad. The ceramic brake pad without asbestos and metals has a good abrasion resistance, and after wearing-in of the brake pad, a layer of a compact lubricating film is formed on the surface of the friction material, so that a lubricating rolling friction can be formed during braking, the abrasion resistance is guaranteed and the service life is prolonged, besides, the ceramic brake pad has a good mechanical strength and physical property, the braking noises and the ash formation rate of friction are low, the ceramic brake pad is easy to clean, and the environment is protected.
Description
Technical field:
The present invention relates to brake block processing art field, be specifically related to a kind of do not have ceramic brake that asbestos do not have a metal mold with and production technology.
Background technique:
Brake block also is brake rubber block.In the brake system of automobile, brake block is the breaking piece of most critical, and the quality of all braking effects all is that brake block plays a decisive role, so the brake block of agreeing is the patron saint of people and automobile.Brake block generally is made up of steel plate, bonding thermal-protective coating and brake pad.Wherein thermal-protective coating is made up of adiabatic material, and purpose is heat insulation.Brake pad is made up of friction material, tackiness agent, is compressed in during brake to produce friction on brake disc or the brake drum, thereby reaches the purpose of vehicle deceleration brake.
The friction factor of brake block has determined the size of braking force, and friction factor has also played decisive role to the stability of the vehicle operating in brake compensation and the braking.The reduction of friction factor can cause the sizable variation of braking ability, perhaps can cause stopping distance significantly to increase, and causes the threat of personal safety.The friction factor of good brake block must be enough high, and under various driving conditions, can keep stable by chance.
General brake block can be divided into asbestos type brake block, semipermanent mold brake block.The friction material of asbestos type brake block mainly is to be main with asbestos fiber, yet asbestos are harmful materials, and braking effect is poor.The friction material of semipermanent mold brake block be with coarse Steel Wool as reinforced fibers and important mixture, need higher retardation pressure in use, produced simultaneously noise is bigger.
Summary of the invention:
The technical problem that the present invention solved is to provide a kind of cost of production low, and brake noise is low, effective, the ceramic brake that the no asbestos of long service life do not have a metal mold with and production technology.
The technical problem that the present invention solved adopts following technological scheme to realize:
A kind of do not have a ceramic brake that asbestos do not have metal mold, comprises steel backing and friction material, and it is characterized in that: said friction material is processed by following raw materials by weight percent:
A kind of do not have asbestos not have the production stage of ceramic brake of metal mold following:
A, take by weighing raw material and take by weighing aramid fiber, BaSO accurately by raw material components
4, fiber, Al (OH)
2, crystalline flake graphite, cashew nut shell oil friction powder, coke;
B, mixed material are put into the raw material that weighs up in the batch mixer and are mixed, and incorporation time is 5-10 minute;
C, compression moulding are taken out subsequent use after forming brake pad to mixed prepared using mould compression moulding;
D, steel backing are handled steel backing cleaning, ball blast are being sprayed glue after drying;
E, press compacting are pressed into brake with the brake pad of steel backing of handling well and compression moulding through press;
F, post-processed with brake block with drying oven on forced convection heat, polishing, flat stone mill handle, the chamfering of slotting is as required then carried out whole brake block ablation processes and is sprayed chalk line;
G, annex are installed and are utilized rivet that annex is installed on the brake block.
The beneficial effect that the present invention has is: the present invention has good wear resistance, and after the brake block break-in, friction material surface forms the fine and close lubricating film of one deck; This forms a kind of lubricated rolling friction when making brake, has guaranteed wear resistance, has increased working life; Have excellent mechanical intensity and physical property; Brake noise is low, and low being prone to of one-tenth ash rate of friction cleaned, and protected environment.
Embodiment:
For technological means, creation characteristic that the present invention is realized, reach purpose and effect and be easy to understand and understand, below in conjunction with specific embodiment, further set forth the present invention.
Embodiment
Take by weighing aramid fiber 3%, BaSO accurately by raw material components
430%, fiber 20%, Al (OH)
27%, crystalline flake graphite 15%, cashew nut shell oil friction powder 10%, coke 15%; The raw material that weighs up put in the batch mixer mix, incorporation time is 5-10 minute; Behind mixed prepared using mould compression moulding formation brake pad, take out subsequent use; Steel backing cleaning, ball blast are dried the back spraying glue; The brake pad of steel backing of handling well and compression moulding is pressed into brake through press; With brake block with drying oven on forced convection heat, polishing, flat stone mill handle, the chamfering of slotting is as required then carried out whole brake block ablation processes and is sprayed chalk line; Utilize rivet that annex is installed on the brake block.
The brake block that makes is placed on the constant speed experimental machine tests, the result is as shown in table 1.
Can find out that from table 1 data the friction factor of the brake block that the embodiment of the invention obtains changes very little.In the temperature rise period, friction factor is at 0.23-0.36, and at 0.33-0.39, wear rate is little at the temperature-fall period friction factor, is stabilized in 0.02-0.3*10
-7Cm
3/ N.m is up to state standards.Use through numerous vehicles, braking effect is good, friction factor comparatively steadily, noiseless, good, the long service life of wear-resisting property in moderate, the braking process of wear rate.
More than show and described basic principle of the present invention and major character and advantage of the present invention.The technician of the industry should understand; The present invention is not restricted to the described embodiments; That describes in the foregoing description and the specification just explains principle of the present invention; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various changes and modifications, and these variations and improvement all fall in the scope of the invention that requires protection.The present invention requires protection domain to be defined by appending claims and equivalent thereof.
