Description

technical field [0001] The invention relates to the technical field of rubber and plastic foam products, in particular to a graphene regenerated rubber and plastic foam granule for shoe soles and a preparation method thereof. Background technique [0002] Rubber products are high-molecular compound products with high elasticity, high stretchability and high insulation, which are divided into natural rubber and synthetic rubber; EVA is the abbreviation of ethylene-vinyl acetate copolymer. In addition to the good elasticity of rubber, it is different from rubber in terms of flexibility, low temperature resistance, transparency, surface gloss, etc. Products made of EVA resin can still have good flexibility at -50°C. The most prominent features of the product are the blending performance with fillers, coloring performance, easy hot pressing, cutting, gluing, and good processability of lamination. These characteristics are far superior to rubber. [0003] With the continuous exp...
