(2) warm process, puts into boiling hot deep fat leaching and scalds 3 ~ 5 seconds, then pull out with alcohol washes, then dry by friction material blank;
(3), steel backing Shot Blasting, then to steel backing gluing;
(4), friction material blank and steel backing are carried out hot-forming, obtain brake block blank;
(5) secondary heat treatment, grinding, fluting chamfering, sand blast, sticky bloop, dress annex, test package warehouse-in is then carried out successively.
Described water law mixing the friction material raw material prepared is added water to be fully uniformly mixed and to form slimy mixture, and in the process of High Rotation Speed and stirring, mixture has carried out next feeding storehouse.
When described water law mixes, the mixed proportion of friction material raw material and water is 1:0.8 ~ 3.
Described pre-molding carries out in the conditionity of vacuum.
The present invention is friction plate making method newly developed; adopt the mixing of water slurry method; namely after taking material by formula; add water to stir; achieve Agitation and mixing so to greatest extent, stirrer adopts special material simultaneously, under the effect of water; raw material are protected to greatest extent, length of staple and the physical property of material own of original material can not be cut off.After realizing Homogeneous phase mixing, mixture forms a pile mud, in the process of High Rotation Speed and stirring, mixture has carried out next feeding storehouse, due to High Rotation Speed blanking, if in the direct mould of the mixture of sludge-type, under the conditions such as vacuum, mud is pressed, and mixture forms slug press, and moisture is evacuated, material is pressed into type, avoid the stratification of material, and decrease the dust pollution in process, operating environment improves.
Present invention uses special raw material and produce friction material, use friction material to have higher intensity, the coefficient of friction is high, and has high temperature resistant degree characteristic, good thermal stability.And in production method, warm process has been carried out to friction material in the present invention, reduce friction material in use high temperature when reduce oxidation, the working life of friction plate can be improved.
The invention has the beneficial effects as follows: intensity of the present invention is high, anti-oxidant, high temperature resistant, long service life, good thermal stability, and friction factor is high, the feature of environmental protection of production is good.
