Abstract

The invention provides a method for producing a foam material in a rubber mold. The method includes that hard material and a soft material are mechanically mixed; the hard materials is formed by melting extruding and granulating of oil-extended rubber, polystyrene, K resin, polyphenyl ether and/or heavy calcium powder; the soft material is formed by mixed smelting and granulating of oil-extended rubber, methyl vinyl silicone rubber, C5 petroleum resin, foamer AC and expended-microsphere foamer; the oil-extended rubber is formed by mixing of a styrene-butadiene-styrene segmented copolymer and softening oil. The invention further provides a sole material produced by the method for producing the foam material in the rubber mold. The foam sole material produced with the method has the advantages of light weight, wear resistance, cold resistance, good production performance, high production efficiency, reclamation, environment friendliness and the like.

Description

technical field [0001] The invention belongs to the field of shoe material processing, and in particular relates to a processing method of foaming material in a rubber mold and a shoe sole material prepared by the method. Background technique [0002] The comfort level, service life, and special functions of shoes are all related to the performance of sole materials to a large extent. Ordinary shoe soles are not environmentally friendly because the preparation materials contain chlorine, lead, and polycyclic aromatic hydrocarbons. The cooling rate of ordinary shoe materials is small, and the cooling time is long. After the shoe is formed, it takes a long time to cool down and cool down, resulting in low production efficiency of the shoe. Ordinary shoe materials also have defects such as heavy weight, poor wear resistance, no cold resistance, poor processing performance, and non-recyclable utilization. Contents of the invention [0003] The technical problem to be solved ...
