Internal foaming rubber of dual density Goodyear outsole and preparation method thereof

Abstract

An internal foaming rubber of a dual density Goodyear outsole and a preparation method thereof. The internal foaming rubber of a dual density Goodyear outsole is prepared by the method of: weighing 800-1000 weight parts of natural rubber, 500-700 weight parts of styrene butadiene rubber, 1100-1300 weight parts of reclaimed rubber, 50-70 weight parts of activated zinc oxide, 40-50 weight parts of stearic acid, 20-30 weight parts of antioxidant, 700-800 weight parts of N330 carbon black, 400-500 weight parts of light calcium carbonate, 80-120 weight parts of machine oil, 200-250 weight parts of phenolic resins, 15-20 weight parts of vulcanizing agent, 35-45 weight parts of promoter, 10-20 weight parts of foaming agent and 10-20 weight parts of foaming agent; plasticating the natural rubber, mixing the natural rubber with styrene butadiene rubber and reclaimed rubber, uniformly dispersing and storing for one day; adding the rubber compound into an internal mixer, adding carbon black, light calcium carbonate and phenolic resins, pressing a ram piston, lifting the ram piston 40-100s later; adding activated zinc oxide, stearic acid, antioxidant, foaming agent and machine oil, pressing the ram piston and discharging the materials after load stabilization of the internal mixer; adding the obtained materials into an open mill, pulling out three channels and adding promoter, vulcanizing agent and urea; making five triangle packages after rubber mixing, removing a sheet and hanging; detecting; putting qualified mixed stock in the open mill for thermal aging and processing the mixed stock into a required prescribed shape.

Description

technical field [0001] The present invention relates to a kind of foamed rubber, specifically to a kind of double-density Goodyear outsole with high-strength rubber on the outside and foamed rubber inside, the foamed rubber inside the Goodyear outsole, and the foamed rubber method of preparation. Background technique [0002] The Goodyear structure follows the vocabulary of the rubber industry, which is a special processing technology for soles. The advanced seam and glue technology is used to tightly combine the upper and the sole with the welt and the rubber midsole. This kind of rubber outsole is generally heavy in quality and heavy to wear, and more rubber is used in the production process, and the cost is higher. When a kind of rubber is used for the whole body, the internal high-performance rubber has no use value for the quality of the sole, and increases the manufacturing cost of the finished shoe. Contents of the invention [0003] The object of the present inv...
