NOVELTY - Foaming sole comprises 50-55 pts. wt. ethylene-vinyl acetate, 20-25 pts. wt. olefin block copolymer, 5-10 pts. wt. maleic anhydride grafted ethylene-vinyl acetate, 3-12 pts. wt. graphene oxide flame retardant, 5 pts. wt. talc powder, 4 pts. wt. anti-wear agent, 0.4 pts. wt. stearic acid, 0.4 pts. wt. zinc stearate, 0.9 pts. wt. zinc oxide, 0.5 pts. wt. flow agent, 0.55 pts. wt. crosslinking agent, and 0.6 pts. wt. blowing agent. USE - Used as foaming sole. ADVANTAGE - The method: is simple, achieves beneficial effects of improving tear resistance of sole and unexpected results, has flame retardant performance of sole, and reducing length of sole wear scar. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing foaming sole comprising (1) pouring talc powder, anti-wear agent, stearic acid, zinc stearate, zinc oxide, flowing agent into the mixer, pouring ethylene-vinyl acetate, olefin block copolymer, maleic anhydride grafted ethylene-vinyl acetate, graphene oxide flame retardant into internal mixer, adjusting air pressure 0.75-0.8 MPa, circulating water pressure 0.15-0.2 MPa, the first internal mixing and turning, placing cross-linking agent and foaming agent in same feeding bag, shaking and placing into mixer, turning over the material for the second time, turn on the mixer and pouring mixed materials into roller hopper, (2) transferring material of roller hopper to open mill, pouring onto wheel table, the open mill temperature is 65-75 degrees C, adjusting roller wheel distance to 6 mm, and dropping tablet into material tray after mixing, adjusting roller track to 1.6 mm, and the beam is turned thin twice, adjusting roller wheel pitch to 2.6 mm, adjusting falling material to other direction, pushing into wheel table, kneading and pressing triangle bag to fall into tray, adjusting wheel pitch of roller to 6 mm, after mixing thinned material on wheel table, cutting material and delivering reel to granulator immediately, (3) extruding and shaping material by screw in granulator, the screw temperature is set to 80 degrees C in zone A, 80 degrees C in zone B, 85 degrees C in zone C, 85 degrees C in zone D, 90 degrees C in zone E, extrusion frequency conversion speed is set to main feed 45 Hz, press roller 36 Hz, cutting material 16 Hz, the pellets immediately enter four-stage cyclone cooling barrel, and passing through vibrating screen to obtain a foamed sole material meter with uniform particles and a temperature /(50 degrees C, (4) pouring foamed sole material into the foaming mold, closing, and heating, controlling temperature 170-174 degrees C, for 240-300 seconds, after mold is opening, taking out sole semi-finished product , cooling for 12 hours, eliminating lack of materials, dead materials, edge cracking or unqualified semi-finished shoe soles with length error exceeding plus minus 2 mm, roughening qualified semi-finished shoe soles by leather wheels, and grounding bottom and side skins of semi-finished shoe soles away to obtain small foamed semi-finished products, and (5) placing small foamed semi-finished product into the hydraulic mold, closing, and passing to heating station of hydraulic molding machine for heating and set temperature, pulling mold out, switch to cooling station, and cooling with water for 240-300 seconds, pulling out and open mold, pulling product out of mold and placing on inspection platform, removing unqualified shoe soles with clipped, missing materials and wrinkled external walls, and trimming and sorting qualified products to obtain foamed soles.
