[0077] Utilize the device for preparing friction parts of the present invention to prepare friction parts, the structural diagram of the device is as follows image 3 As shown, the distance between the two rollers of the roller film formers 110, 120, 310 and 320 is 0.2mm, the curing unit 400 is a drying box, and the feeders 130, 140, 330 and 340 are equipped with materials for forming For the silica gel of the first film layer and the second film layer, a cloth for forming a mesh layer was wound on a screen roll, and the cloth had a thickness of 0.1 mm and a through hole of 200 meshes. The steps of using the device to prepare friction parts are as follows:
[0078] (1) The feeder 130 feeds the material, and the amount of glue per unit time is about 30% of the total amount of glue per unit time. The roller film former 110 is scraped once to form a thin layer of glue on the flexible template.
[0079] (2) The vacuum brush 150 punctures the pores of the thin layer of rubber to r...

[0087] Utilize the method for preparing the friction part of the present invention, use the foam electrode as the raw material of the mesh layer, prepare the friction part, the specific steps are as follows:
[0088] (1) Flatten the foam electrode with a roller machine;
[0089] (2) cutting the foam electrode flattened in step (1) to obtain the foam electrode after cutting;
[0090] (3) Silica gel is coated on the surface of the acrylic rigid template, wherein the surface of the acrylic rigid template has an array hole structure, and the thickness of the coated silica gel is 200 microns;
[0091] (4) Place the rigid template coated with silica gel obtained in step (3) in a vacuum drying oven for degassing treatment for 15 minutes to obtain degassed silica gel;
[0092] (5) Place the cut foam electrode flatly on the surface of the degassed silica gel layer obtained in step (4), to obtain a friction part intermediate;
[0093] (6) drying the friction part intermediate to obtai...
