Description

The manufacture method of car clutch face sheet
Technical field
The present invention relates to a kind of manufacture method of car clutch face sheet.
Background technology
The constituent of car clutch face sheet can be divided three classes, i.e. framework material, binding material and packing material.Packing material is functional filler, and it gives the enough coefficient of frictions of clutch surface and friction stability.Binding material is formed by rubber and mixed with resin usually, but to have very strong pliability adhesion strength low for rubber, but resin-bonded intensity is high crisp and frangible.In traditional handicraft, the production technology of car clutch face sheet is, first by rubber mixing machine forceful action, by evenly mixing to rubber, resin and various packing material; Add organic solvent again, after dissolving, make thickness rubber cement; The framework material containing glue is made again with cement dip framework material; Then the processing such as drying, winding, hot pressing, heat treatment are carried out.Application number be 200910063846.9 Chinese invention patent disclose a kind of clutch face sheet for cars and production method thereof, the each component of this clutch surface is by weight: water soluble phenol resin 10-20, aluminium oxide 0.5 ~ 1.5%, crystalline flake graphite 4 ~ 8%, antimonous sulfide 0.6 ~ 1.2%, powdered whiting 6 ~ 10%, brass breeze 8 ~ 12%, magnetite powder 6 ~ 10%, Cab-O-sil 3 ~ 8%, barium sulfate 12 ~ 18%, PNBR 6 ~ 15% and water stir makes suspension, flood the basalt fibre of 15 ~ 25% again, through super-dry, be wound around, compacting, heat treatment, machining obtains product.This invention improves temperature tolerance and the wearability of clutch face sheet for cars.Application number be 201019146031.7 Chinese invention patent disclose a kind of novel non-rubber winding clutch facing, it adopts water soluble phenol resin to be binding material, water soluble phenol resin is raw material by the phenol of 100 weight portions and the formaldehyde of 105 ~ 115 weight portions, under the effect of the base catalyst of 0.1 ~ 0.2 weight portion, be prepared from through condensation reaction, the solid contents that water soluble phenol resin obtains after drying accounts for 50 ~ 55 of former phenolic resin weight.This invention by this for water soluble phenol resin novel binders for the production of automobile-use clutch surface, because water soluble phenol resin binding agent has that heat fading is little, thermal expansion is little and safety coefficient comparatively advantages of higher, so the clutch surface made has good heat resistance, coefficient of friction is higher and steady, the advantages such as heat fading is little, wearability is good; Also there is clutch simultaneously steady, the features such as especially thermal expansion is less.Obviously, above-mentioned multiple technologies scheme follows same production technology, namely mix, dissolve, impregnation, drying, winding, hot pressing, heat treatment, the production efficiency of this production technology is not high, and the clutch surface that above-mentioned multiple technologies scheme obtains is after because of friction, temperature raises, the stationarity of clutch also can reduce significantly.
Summary of the invention
The present invention will solve the problems of the technologies described above, and provides a kind of production stage to simplify and clutch surface still has the manufacture method of the car clutch face sheet of the stable advantage of clutch after temperature raises.
The technical scheme that the present invention solves the problem is as follows:
1. batch mixing: rubber 25wt% ~ 30wt%, phenolic resins 10wt ~ 15wt%, surplus is functional filler, mixing;
2. gluing: refining is injected the feed liquid chamber with roll, uses roll that described glue even roller is applied to fibre framework materials surface;
3. be wound around: have the fibre framework materials of refining to turn to the blank of circular ring surface uniform roller coat by wrapping machine;
4. suppress: described blank is hot-forming by hot press;
5. thermal finalization: hot-forming blank is heat-treated stage by stage; First stage 155 DEG C ~ 165 DEG C, 3.5h ~ 4.5h; Second stage 185 DEG C ~ 195 DEG C, 6.5h ~ 7.5h; Phase III 215 DEG C ~ 225 DEG C, 3.5h ~ 4.5h;
Containing curing agent in described phenolic resins, the consumption of adjustment curing agent makes the stream of described phenolic resins apart from being 120 ~ 160mm, makes described phenolic resins have maximum mobility 145 ~ 155 DEG C time, and not exclusively crosslinked in pressing process; The mensuration of described stream distance adopts GB HG-T2753-1996 to measure.
In technique scheme of the present invention, traditional impregnation and drying steps gumming step are replaced, save trouble and labor, greatly improves production efficiency.Seem simple replacement step in fact so not simple.If adopt traditional mixture recipes, traditional resin, traditional rubber, then cannot adopt gumming step of the present invention, because gluing of the present invention in contrast to the upper obviously shortening of impregnation time, occur significantly to change with the exposure level way of contact of glue, according to original glue, after adopting gumming step of the present invention, the fibre framework materials infiltration glue obtaining kiss-coating is insufficient, even can not permeate, this is also surface, key is that loosely organized, product is defective at the stock of the clutch surface made after compacting.The present inventor is through long-term research, creatively propose the basic theories of replenishment of process route, change mixture recipes, adjustment suppressing heat sizing parameter, after having paid performing creative labour, impregnation in process route and drying gluing are replaced, mixture recipes is revised as " rubber 25wt% ~ 30wt%; phenolic resins 10wt ~ 15wt%, surplus is functional filler ", thermal finalization is divided into three phases; After the organic assembling adjustment of above-mentioned multiple features, finally make novel clutch surface.And this clutch surface has the unexistent advantage of traditional clutch surface, that is, after temperature significantly raises, clutch surface of the present invention can also ensure the stationarity of clutch.
Phenolic resins in technique scheme of the present invention and existing phenolic resins different, this is not realize by revising the modification of group.Well known, phenolic resins is the powder of alcohol dissolubility, is commonly called as phenolic moulding powder, can mix with various organic-inorganic filler.This area is also known, and will have curing agent could be completely crosslinked in phenolic resins, and competence exertion cementation, curing agent also claims curing agent or crosslinking agent.Current this area, when using phenolic resins, wherein with the addition of a certain proportion of curing agent.For ease of describing, described in batch mixing step of the present invention, phenolic resins also refers to the phenolic resins being added with curing agent.Mention phenolic resins of the present invention above and existing phenolic resins is different, difference is realized by the consumption adjusting curing agent just.Give an oral account according to inventor, this area had not been thought the curing agent of the ubiquitous routine dose in known phenolic resins will to be adjusted, thus obtain stream apart from the phenolic resins being 120 ~ 160mm, after reducing the content of curing agent, change is that phenolic resins has maximum mobility 145 ~ 155 DEG C time the most significantly, and not exclusively crosslinked in pressing process.Just because of this, the problem of traditional phenolic resins gluing difficulty is solved; Also because so, compacting of the present invention, although consistent with the compacting technological parameter of prior art, the effect that its effect will reach in other words in theory there occurs change between quietly, and compacting of the present invention more suitably saying is pre-stamped.In fact with combined with heat treatment together, as above-mentioned, heat treatment of the present invention was divided into for three stages implemented to the real compacting of the present invention: first stage 155 DEG C ~ 165 DEG C, 3.5h ~ 4.5h; Second stage 185 DEG C ~ 195 DEG C, 6.5h ~ 7.5h; Phase III 215 DEG C ~ 225 DEG C, 3.5h ~ 4.5h.The present invention and prior art also have a significant difference to be: rubber content of the present invention raises, and resin content reduces, and in prior art, rubber content is generally at below 20%wt, as 200910063846.9 is 6 ~ 15wt%; In prior art, resin content is generally at about 20wt%, as 200910063846.9 is 10 ~ 20wt%.This is because, after reducing the curing agent content in resin, the ratio of phenolic resins improves virtually, this is not main, importantly the activity of resin obtains enhancing, also just because of this, resin of the present invention, be equivalent to the equivalent of resin of the prior art about 1.5, the resin that namely resin of the present invention uses 1g to be equivalent to prior art uses 1.5g.This high efficiency performance makes rubber constituent and filler composition directly be benefited, and can increase their reasonable occupancy, and finally make product be benefited, play the function affect of functional filler to a greater degree, played the toughness effect of rubber to a greater degree; Thus make the aspects such as the obtained clutch surface of employing the inventive method has better performance, and outstanding behaviours is in the stationarity of clutch, and the ride comfort namely during automobile gear shift is improved, and also shows rub resistance, friction stationarity.
