Preparing a reinforcing material: preparing raw materials required by preparing a reinforcing material, wherein the raw materials are made of synthetic fibers, glass fibers and metal fibers; respectively soaking synthetic fibers, glass fibers and metal fibers in thermosetting resin aqueous solution, respectively taking out fiber yarns, drying by drying equipment, respectively twisting the synthetic fibers, the glass fibers and the metal fibers to compound the synthetic fibers, the glass fibers and the metal fibers into one strand to obtain three strands of resin composite fiber bundles, and respectively false twisting the three strands of composite fiber bundles to obtain the processed resin composite fiber bundles;
and (3) rubber material finished product: starting a main motor of the glue extruding machine, preheating the glue extruding machine to enable the temperature of an extruding head to reach 80 ℃, the temperature of a machine body to reach 60 ℃ and the temperature of a screw to reach 50 ℃; then pre-extruding glue, stopping pre-extruding when the temperature of the extruded glue reaches 80 ℃, and closing the pre-extruding hole; then opening a glue inlet of the extrusion head, extruding and wrapping by using a slow gear, and adjusting the speed to a fast gear to produce after the sizing material on the fiber bundle line is basically uniform; the glue extruder and the winder synchronously run, the linear speed is kept at 55m/min, three composite fiber bundles coated with glue are obtained, and the encapsulation is finished; and the blank of the clutch facing is obtained by winding through a winding machine and can be used for the next production of the clutch facing product.
Wherein, the drying of the reinforcing material is carried out by taking out any soaked fiber from the soaking solution by a user, then placing the cellosilk on a silk feeding table, discharging water flowing out of the fiber through a round opening on the silk feeding table, dividing the cellosilk into threads by the user, then fastening the top end of a thread of cellosilk through an annular elastic band, then sleeving the other end of the elastic band on the surface of a buckle groove 16, controlling a bottom extending column 5 to extend through an external button switch, driving the cellosilk to finally enter the shell 1 from a silk feeding table 17 through an observation window 21 by the bottom extending column 5, finally enabling all the cellosilk to enter the shell 1 along with the continuous extension of the bottom extending column 5 to form suspension, controlling a motor 9 to rotate for 30s by the button switch by the user, controlling a pressing plate 13 to descend through a hydraulic rod 12 after the rotation is finished, collecting the fiber on the surface of the buckle groove 16 through the opening on the surface of the pressing plate 13, make the cellosilk neat, open simultaneously and carry out work with anion generator the inside rotating fan of top case 3, the anion transmits through connecting pipe 4, smooth the cellosilk, then control hydraulic stem 12 resets, clamp plate 13 returns in the top of withholding plate 11, then preheat through external control device control electrothermal tube 19, then through the periphery of flexible post 22 with dry ring 23 propelling movement to cellosilk, the heat of electrothermal tube conveys through steam, the continuous propelling movement of dry ring 23 and the slow rotation of the cellosilk that motor 9 drove, carry out dry work to the cellosilk, after the drying is accomplished, the user supplies air through air supply fan 201, cool off the cellosilk, dry work is accomplished.
In summary, the following steps: the invention adopts a glue squeezing device and selects a solid powdery water-soluble thermosetting phenolic resin to replace the powdery thermoplastic phenolic resin which is dissolved by organic alcohol or acetone organic solvent and used in the traditional production; the novel resin is solid but can be dissolved by water; the phenolic resin is divided into thermosetting phenolic resin and thermoplastic phenolic resin, and the two resins are basically as follows: because of different manufacturing processes, the shapes and the properties of the two prepared resins are different; the thermosetting phenolic resin is in a liquid state, and the thermoplastic phenolic resin is in a solid state. But all the materials can be dissolved only by organic solvents such as organic alcohol or acetone and the like, and are not soluble in water; the production state of the industry for producing the winding type clutch facing needs to be that the liquid thermosetting phenolic resin is not suitable for use, and the thermoplastic phenolic resin is most suitable, and can be used only after being added with a curing agent when used, and needs to be dissolved by an organic solvent to be prepared into liquid for use, so that the potential safety hazard is brought to production by adopting the resin; the thermosetting phenolic resin selected by the invention is solid and can be dissolved by water, so that potential safety hazards are eliminated.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
