Problems solved by technology

However, the current situation of comprehensive utilization in China is far from this plan, especially the utilization rate of converter steel slag known as "inferior cement clinker" is only 10%-20%
The steel slag produced by domestic iron and steel enterprises cannot be disposed of in time, resulting in a large amount of steel slag occupying land and polluting the environment

Abstract

The invention discloses a high-wear-resistant anti-slip EVA composite foam material and a preparation method thereof, wherein the foam material is prepared from the following components: an ethylene-vinyl acetate copolymer, maleic anhydride grafted EVA, an ethylene-octene copolymer, a terpene resin, a wear-resistant anti-slip agent, naphthenic oil, polyisobutene, a foaming agent, an accelerant, stearic acid, zinc stearate, zinc oxide, dicumyl peroxide and an antioxidant, wherein the wear-resistant anti-slip agent is a modified steel slag/graphene oxide composite material. Compared with the traditional EVA foam material, the high-wear-resistant anti-slip EVA foam composite material prepared by the invention has good wear resistance and good anti-slip performance under the condition of a lowfiller addition amount, has good processability and good mechanical properties, is simple in the operation of the manufacturing process, energy saving and environmentally friendly, and has wide application prospects and market requirements 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 wear-resistant anti-slip EVA composite foam material and a preparation method thereof. Background technique [0002] EVA is a rubber-like thermoplastic. Compared with polyethylene, due to the presence of vinyl acetate, the regularity and crystallinity of the molecular chain are reduced, and the flexibility of the molecular chain is improved. It has excellent comprehensive physical and mechanical properties and good processing. performance. EVA foam material is a non-toxic, low-density, high-elasticity, high-specific-strength foam material with good load-absorbing capacity, so it is widely used as a material for various shoe soles. However, EVA foam materials often have poor wear resistance, small friction coefficient, insufficient anti-skid performance, and short service life. With the development of social and economic levels and the advancemen...
