Non-slip heat aging resistant EVA and NR composite foaming material and preparation method thereof

Abstract

The invention discloses a non-slip heat aging resistant EVA and NR composite foaming material and a preparation method thereof, and belongs to the field of polymer composite foam materials. The composite foaming material comprises the following raw materials, in parts by weight: 97-100 parts of an ethylene-vinyl acetate copolymer, 5-10 parts of NR, 1-10 parts of a composite non-slip heat aging resistant agent, 2.5-3 parts of a foaming agent AC, 0.5 part of stearic acid, 0.6 part of zinc stearate, 0.8 part of zinc oxide, and 0.2 part of dicumyl peroxide, wherein the composite non-slip heat aging resistant agent is a graphene-white carbon black nano composite material. The method provided by the invention successfully prepares the graphene-white carbon black nano composite material by reducing graphene oxide in a green environmentally-friendly manner while depositing growing nano white carbon black on the surface of the graphene oxide; the graphene-white carbon black is adopted as the composite non-slip heat aging resistant agent, and has a small addition amount, good compatibility with a substrate, easy dispersion and an excellent non-slip effect; and the composite foaming material has excellent slip resistance.

Description

technical field

[0001] The invention belongs to the field of polymer composite foam materials, and in particular relates to an anti-slip, heat-resistant and aging-resistant EVA, NR composite foam material and a preparation method thereof. Background technique

[0002] EVA foam composite materials are widely used in shoe materials, construction, packaging and other fields due to their advantages such as low density, strong cushioning and shock absorption capacity, and low temperature resistance. Because the EVA material, like most polymer plastics, causes its anti-skid performance to decrease after foaming. Such a high abrasion will seriously restrict its application in some shoe materials with high anti-skid requirements. Due to abrasion, product failure may occur in severe cases. Therefore, the research of EVA and NR composite foam materials with anti-slip and heat-resistant aging has important application value in the field of shoe materials.
