The background of thesis is Middle of 90's, Kailuan mineral to put forward first the PVC take the surface gum flexibility bad, the coefficient of friction is low, particularly at carry to take the wet coal in water, easy beat superficially in the belt conveyer slippery, the influence carries the efficiency. The item mostly research to built in production specifications of push to wipe the method, namely passes two pedestals extrude the machine to crowded, face to the be soiled belt core draw the surface gum to finished. The mostly modified material is Ethylene-Vinyl acetate-Carbon terpolymer. In our experimentation, we mainly studied the thermoplastic elastomer to resist the influence of the wet slippery inflaming retarding belt conveyer function in push wipe method produce craft. Passing the experimentation, we process to research and discuss in several facets:1) PVC/elvaloy compatibility for polymer blend totally anticipating, 2) PVC/elvaloy multipolymer processes the function totally, 3) PVC/elvaloy the comparison of polymer is everything totally to the polymer blend reasonableness can of influence, 4) PVC/elvaloy totally the comparison of polymer to the influence of belt conveyer various functions. Passing experimentation, we found rewarding in several facets: 1) anti-skid capability of belt conveyer of inflaming retarding, 2) Working in application of fire retardant and antistat, 3) Flow process of PVC/elvaloy multipolymer.
