The technical characterstic of the present invention and effect be: in the raw material of the present invention, and modified graphene Nano filling and potter's clay complement one another；Adopt above-mentioned preliminary preparation technology, first scrap rubber can be carried out preliminary desulfurization, then the interpolation time of modified graphene Nano filling, and interpolation component can so that scrap rubber can carry out abundant desulfurization in specific temperature range, simultaneously can so that the product of later stage production be reduced to 0.065 with the coefficient of friction COF reducing this product by 0.215, wear rate reduces on 86.10%, and product is in friction process, surface softening and decomposition are inhibited, the movable thin film on its surface can protect friction surface better, therefore the interaction force of interiors of products material is added, therefore initial bonding strength and the holding power of product are also improved.And make the cracking temperature of this product be increased about 220 DEG C by 80, hence in so that the heat resistanceheat resistant performance of product is remarkably reinforced, and the more important thing is the generation adopting above-mentioned formula and above-mentioned technique can reduce by-product and toxic products in process of production, and reduce the time of overall manufacturing.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all any amendment, equivalent replacement and improvement etc. made within the spirit and principles in the present invention, should be included within protection scope of the present invention.
