To on the brake clamp support of frame.In braking, grinding is pressed on tread and is cleaned, ensure that wheel pedal mask
There is good surface state, the dust being attached on wheel tread, rusty stain, grease etc. can be removed in vehicle travel process；Together
When, grinding plays the role of adhesion between enhancing wheel track under the moisture states such as rain, snowy day gas, in general, using grinding
When adhesion be not used grinding the period of the day from 11 p.m. to 1 a.m 150%, so as to ensure that motor-car vehicle avoids dallying and beating in braking procedure
It is sliding.The sector product relies primarily on import at present, and domestic several enterprises are developing, but existing product is generally deposited
In abrasion greatly, there is the defects of spark meteor, valuable product during portioned product working status.
The content of the invention
For problem present in background technology, the present invention provides high speed motor car grinding and preparation method, it is intended to
The spark that solves in using grinding subprocess to occur at present by the formula of optimization and rational technical process, easily damage
The problems such as consumption.
To achieve the above object, automobile-used grinding of quick-action of the present invention is the composite material made of a kind of composite material
It is made of phenolic resin, steel fibre, copper aluminium powder, carbon fiber, tungsten carbide, aramid fiber, iron oxide black, nitrile rubber, accelerating agent,
Wherein the weight percent range of each component is phenolic resin 26-28.5%, steel fibre 9-10%, copper aluminium powder 13.5-
15.5%th, carbon fiber 10-12%, tungsten carbide 1-2%, aramid fiber 6.5-8.5%, iron oxide black 6-8.5%, nitrile rubber 7.5-
8.5%th, accelerating agent 12-13.5%.
The present invention also provides a kind of method for preparing high speed motor car grinding, production process route is：Obtain composite wood
Material component be uniformly mixed-is put into molding apparatus-hot pressing-heat treatment-service check-plastic-spraying-inspection-storage.
As a preferred embodiment of the present invention：The hot pressing uses intermittent hot pressing mode.
As a preferred embodiment of the present invention：The intermittent hot pressing mode is followed successively by：Pressure 20Mpa, temperature
120 DEG C, deflate for the first time within 10 seconds after pressurization, 15 seconds second deflation of pressurize, then 15 seconds third times of pressurize are deflated, rear pressurize 15
Minute depanning.
As a preferred embodiment of the present invention：The heat treatment is by the way of being repeatedly heat-treated.
As a preferred embodiment of the present invention：The repeatedly heat treatment is followed successively by：- 95 when curing -80 DEG C/1 is small
DEG C/2 it is small when -110 DEG C/3 it is small when -120 DEG C/4 it is small when -165 DEG C/6 it is small when.
Compared with prior art, the beneficial effects of the invention are as follows：By optimizing component ratio and processing technology, avoid
During grinding sub- use, there is high temperature stress crackle, fire check, friction spark.Meanwhile using intermittent mode of heating
And repeatedly heat treatment optimizes the peeling occurred at present in using grinding subprocess, easy the problems such as consuming.
