Abstract
The invention relates to a sole, in particular to an EVA (Ethylene Vinyl Acetate) sole. The sole comprises the following components in percentage by weight: 48-52 percent of EVA, 18-22 percent of IR (Isoprene RubbeR), 8-10 percent of POE (Polyolefin Elastomer) plastic raw material, 4-6 percent of talcum powder, 0.4-2.6 percent of foaming agent, 0.7-0.9 percent of bridging agent, 1.0-1.6 percent of zinc oxide, 0.8-1.2 percent of magnesium oxide, 0.6-0.8 percent of stearic acid, 0.8-1.2 percent of zinc stearate, 2.5-3.5 percent of resin, 3-6 percent of wear resistant agent, 0.4-0.6 percent of dispersing agent and 0.4-0.6 percent of flow agent. The sole prepared by the formula has the advantages of lightness, good shockproof effect and the like of the normal EVA sole, and also has the advantages of superior wear resistance performance and long wear life.
Description
technical field [0001] The invention relates to a shoe sole, in particular to an EVA shoe sole. Background technique [0002] EVA (ethylene-vinyl acetate copolymer) material has high resilience, high tensile strength, high toughness, good shock resistance, cushioning performance, heat insulation, heat preservation, cold resistance and low temperature performance, can withstand severe cold and exposure, and has closed cells. It has good sound insulation effect, closed cell structure, non-absorbent, moisture-proof, water-resistant performance, and seawater, oil, acid, alkali and other chemical corrosion resistance, so it is widely used in the manufacture of shoe soles. But ordinary EVA soles also have shortcomings: they are not wear-resistant, which affects the service life of shoes. Contents of the invention [0003] In order to overcome the technical problems of non-abrasion resistance and short wearing life of the existing ordinary EVA soles, the present invention provid...
