Abstract

The invention discloses a high-mechanical-strength wear-resistant EVA composite foam material and a preparation method thereof. The foam material comprises the following components: ethylene-vinyl acetate copolymer, maleic anhydride grafted EVA, ethylene-octene copolymer, a composite wear-resistant agent, rosin resin, naphthenic oil, a foaming agent, an accelerant, stearic acid, zinc stearate, zinc oxide, dicumyl peroxide and an antioxidant. The composite wear-resistant agent is a modified white corundum/graphene oxide composite material. Compared with the traditional EVA foam material, the high-mechanical-strength wear-resistant EVA composite foam material prepared by the invention has the advantages that good mechanical properties and wear resistance are obtained under the condition thatthe addition amount of the filler is small; better processability is achieved; the manufacturing process is easy to operate, energy is saved, the environment is protected, and wide application prospects and market requirements are achieved in actual application.

Description

technical field [0001] The invention belongs to the field of polymer composite foam materials, and in particular relates to a high mechanical strength wear-resistant EVA composite foam material and a preparation method thereof. Background technique [0002] Ethylene-vinyl acetate copolymer (EVA) is a rubber-like thermoplastic. Its softness, toughness, transparency, and compatibility with fillers are superior to polyethylene (PE). EVA has excellent comprehensive physical and mechanical properties. properties and good processability. EVA foam materials have excellent resilience, flexibility, good foaming performance and load-absorbing capacity at room temperature, so they are widely used as various shoe sole materials. However, the EVA foam material also has the problems of easy wear and short service life. With the development of social and economic level and the progress of science and technology, the limitations of traditional reinforcing fillers have become increasingly ...
