Using semimetal friction material, without asbestos organic friction material (NAO), powder metallurgy friction material, ceramic frication material etc..With
The continuous development of friction material, ceramic frication material along with having obtained using and promoting for large area the advantages of itself,
And obtaining quick development in recent years, still, traditional ceramic frication material be for ceramic frication material formula,
Preparation technology of ceramic frication material etc. is studied, and the performance of the raw material of use is not improved to be rubbed with reference to ceramics
The preparation technology and raw material proportioning for wiping material are studied, and then cause the development of ceramic frication material to have certain office
It is sex-limited.
And due to easily damaging brake disc containing metal in existing friction material formulation, with external environmental condition such as temperature
There is the phenomenon that noise is big, coefficient of friction is unstable in the change of degree, air humidity, greasy dirt；Braking brake containing metal ingredient
Piece can reduce its coefficient of friction after being mixed with greasy dirt；In addition, the powder that rubbed caused by this kind of friction material containing metal is easy
Other machinery part is caused to damage, service life is short.
Therefore, in order to solve above-mentioned problem, spy of the present invention provides a kind of new technical scheme.
The content of the invention
It is an object of the invention to provide a kind of with phenolic resin modified metal-free ceramic friction material, can solve the problem that existing
Technical ceramics friction material does not improve that material performance, development limitation are big and the metal ingredient that contains can damage the skills such as brake disc
Art defect.
Technical scheme is used by the present invention is directed to above-mentioned technological deficiency：

Further, the friction stabilising agent by nanoscale graphite powder, reinforcing agent, molybdenum disulfide, carborundum according to equivalent
Ratio forms.
Further, the filler is made up of miberal powder, kaolin, calcium carbonate, diatomite according to equal weight proportions.
Further, the preparation method of the phenol-formaldehyde resin modified is as follows：By phenolic resin modified dose, phenolic resin, change
Property bonding agent be placed in mixing channel and stir, control whipping temp be 80-100 DEG C, carried out 15-20min after stirring
Ultrasonication.
Further, described phenolic resin modified dose, phenolic resin, modified bonding agent weight ratio be 1:3:
0.03。
The beneficial effects of the invention are as follows：
1st, the present invention to phenolic resin by being modified so that the performance of phenol-formaldehyde resin modified is more preferably；
2nd, the present invention prepares phenol-formaldehyde resin modified applied to ceramic frication material so that the ceramic frication material of preparation
Rub resistance, intensity, heat resistance are improved；
3rd, the present invention is free of metal ingredient, can solve the problem that the problem of existing friction material damages brake disc, has friction system
The advantages that number is stable, and noise is small, can be widely applied to brake system of car.
Brief description of the drawings
Limited with reference to the accompanying drawings and detailed description technical scheme is further, but require to protect
The scope of shield is not only limited to made description.
Fig. 1 is that one kind disclosed in the embodiment of the present invention is ground with phenolic resin modified metal-free ceramic friction material in friction
