Description
Technical field
The invention belongs to clutch friction plate bonding agent fields, and more specifically more particularly to a kind of automobile clutch is used
Without asbestos yarn impregnating resin.Meanwhile the invention further relates to a kind of automobile clutch preparation processes of no asbestos yarn impregnating resin.
Background technology
Friction member is the main constituent element of friction clutch, and the physical property and mechanical performance of work surface material are straight
Connecing influences the working performance of clutch.Major requirement to material is：Friction coefficient is big and stablizes, and the coefficient of kinetic friction should be as possible
It is close with confficient of static friction；Intensity is high, can absorb impact, and when high speed is not easily broken and peels off；Wear-resisting, high temperature resistant, it is corrosion-resistant and
Good heat conductivity, thermal deformation are small；It should will not be adhered when long-term standing.Furthermore it is required that service life is long, be easily worked with it is inexpensive
Deng.Common rubbing contact-material has powdered metallurgical material, asbestos sill and paper base material.Powder metallurgy production cost is higher,
And asbestos are since its material itself has carcinogenicity, and so gradually superseded, now on the market mainly based on paper base material,
It is interweaved with the mixture of non-asbestos material, plant fiber or both, then it is filled after cohered by resin etc..It is this
Material has porosity, and frictional behaviour is good, kinematics and static friction coefficient similar, and cost is relatively low.Phenolic resin is one kind in paper substrate
Common bonding agent in friction plate production process, traditional impregnating resin solvent processing technology is complicated, is not only brought not for production
Just, and production cost is also greatly increased.

Part, 50 parts of organic solvent.
Preferably, the curing agent is one kind in hexamethylenetetramine, hexamethylene diamine, diethylenetriamine, triethylene tetramine
Or it is a variety of.
Preferably, the organic solvent is alcohol, and the content of alcohol is more than 95%.
A kind of automobile clutch preparation process of no asbestos yarn impregnating resin, includes the following steps：
S1, pretreatment of raw material：Phenolic resin is crushed by pulverizer first, is then added into distillation still, and is added
The 5-10% for entering organic solvent total amount carries out distillation processing in 10-30 minutes by a definite date in the environment of temperature is 150-180 DEG C,
To reduce the content of the free phenol in phenolic resin；
S2, raw material mixing；Phenolic resin slurries in distillation still are taken out, then itself and curing agent are put into togerther in blender
It is slightly mixed, then puts it into pulverizer and crush；
It is prepared by S3, solution；Raw material after crushing is poured into blender, then by remaining organic solvent during stirring
It is added in blender, finally raw material is broken into resin solution under the action of blender, is so far machined.
Preferably, in the step S1, when being processed to phenolic resin by distillation still, distillation still also needs to carry out
Vacuumize process.
Preferably, the mesh number after phenolic resin crushes in the step S1 is 150-170 mesh.
Preferably, the model F-400 pulverizers of pulverizer used in the step S2.
Compared with prior art, the beneficial effects of the invention are as follows：The present invention first passes through distillation still to reduce in phenolic resin
Then free phenol mixes it with curing agent, break into phenolic resin, curing agent, organic solvent together finally by blender
Slurries, not only step is simple, but also effectively raises the performance of phenolic resin, so that the quality of entire product is able to
It is promoted.Compared with the no asbestos yarn impregnating resin of traditional clutch, simple production process of the present invention and adhesive effect is more preferable.
