| titleOfInvention | Friction material and production method thereof |
| abstract | To improve wear resistance of friction materials and guarantee thermal decay stability of the friction materials, the invention provides a friction material and a production method thereof. Technical key points of the method comprises: (1) mixing, which comprises a first step of preparing materials consisting of 8 to 18 wt% of a phenolic resin, 1 to 10 wt% of vermiculite powder, 3 to 10 wt% of cryolite, 1 to 10 wt% of anglesite, 10 to 25 wt% of composite fibers, 3 to 10 wt% of cellulosic fiber, 1 to 5 wt% of brown aluminum oxide, 1 to 10 wt% of alumina, 3 to 15 wt% of light calcium carbonate , 1 to 5 wt% of zinc stearate, 2 to 25 wt% of barite powder, 1 to 5 wt% of carbon black, 3 to 15 wt% of cashew nut shell oil friction powder, 3 to 15 wt% of glass fibers and 10 to 30 wt% of a friction increasing material and a second step of adding the above-mentioned materials into a blender mixer and uniformly stirring the materials to obtain a mixture; (2) hot press molding, which is a step of subjecting the mixture to hot press molding at a temperature of 150 to 155 DEG C under a pressure of 250 kg/cm<2> by using a die; and (3) sulfuration, which is carried out on a product obtained after hot press molding so as to obtain the friction material, wherein sulfuration temperature is 150 to 155 DEG C and sulfuration time is 4 to 6 h. |
