METHOD FOR MANUFACTURING TOTAL RUBBER TIRE MADE OF WASTE TIRE AS RAW MATERIAL, METHOD FOR FILING CRUSHED RUBBER POWDER MIXTURE, AND TOTAL RUBBER TIRE USING WASTE TIRE AS RAW MATERIAL

摘要

PROBLEM TO BE SOLVED: To manufacture a total rubber tire by a relatively simple method with a waste tire as a raw material. SOLUTION: The method for manufacturing the total rubber tire with the waste tire as the raw material comprises the steps of separating and removing metal pieces or a crushed powder containing the metal pieces from the crushed powder of the waste tire 20 having one side of 0.1 to 0.5 mm or preferably 0.1 to 0.2 mm, adding a binder or a binder and a foaming agent and/or a kneaded rubber to the crushed powder after removing the pieces or the crushed powder containing the pieces, and manufacturing a crushed rubber powder mixture. The method further comprises the steps of pressurizing, press injecting and filling the crushed rubber powder mixture to be cast in a mold, heating the mixture in the mold, foaming, molding and vulcanizing the mixture to manufacture the total rubber tire.
