Abstract

The invention discloses a preparation process for producing a damping sheet by virtue of waste rubber. The preparation process comprises the following steps: firstly, crushing the waste rubber, and performing high-temperature desulfurization, filtration and kneading stirring; then adding a modified graphene nanofiller, N-isopropylmaleimide-methyl methacrylate, tetrafluoroethylene-perfluorinated alkylvinylether copolymer fibers and polymethyl methacrylate into a stirring kneader, adding isobutylene, white carbon black and carbon black into the kneader, and transferring the materials into a stirring device after kneading stirring; next adding other materials into the stirring device; finally performing mixing and extrusion. According to the preparation process, the friction coefficient of a product can be reduced, the wear rate is lowered, and in a friction process of the product, surface softening and decomposition are inhibited to increase interacting force of the materials in the product so as to increase the initial adhesion and permanent adhesion of the product.

Description

technical field [0001] The invention relates to the technical field of sheet production, in particular to a preparation process for producing damping sheets using waste rubber. Background technique [0002] w rafters and hafnium hafnium hafnium tires of the Weihua split dendrobium Yang Jiamo Shuiping (Department of Chemical Engineering, Wuhan Institute of Chemical Technology, Wuhan, 430100) (Wuhan Hongyi Industrial Company, Wuhan, 430100) Abstract An advanced catalytic cracking treatment technology for waste rubber tires was developed, The indium particles of waste rubber tires passing through the reactor are catalytically cracked into cracked gas, gasoline fraction, diesel fraction and heavy oil fraction, and the residual solid can be processed into carbon black. Various products have been tested, and their physical and chemical indicators and performance have reached the user Require. This is an effective way to reduce environmental pollution and turn waste into wealth. ...
