Abstract

The invention discloses an anti-slip, heat-resistant and aging-resistant EVA, NR composite foaming material and a preparation method thereof, belonging to the field of polymer composite foaming materials. The composition of raw materials is calculated in parts by weight: 97-100 parts of ethylene-vinyl acetate copolymer, 5-10 parts of NR, 1-10 parts of composite anti-skid heat-resistant aging agent, 2.5-3 parts of foaming agent AC, 0.5 parts of stearic acid 0.6 part, 0.6 part of zinc stearate, 0.8 part of zinc oxide, 0.2 part of dicumyl peroxide; Described composite antiskid heat-resistant aging agent is graphene-white carbon black nano-composite material. The present invention successfully prepares a graphene-white carbon black nanocomposite material by depositing and growing nano-white carbon black on the surface of graphene oxide and reducing graphene oxide in an environmentally friendly manner. Graphene-silica is used as a composite anti-slip heat-resistant aging agent, with less addition, good compatibility with the matrix, easy dispersion, excellent anti-slip effect, and excellent anti-slip performance.

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. [0003] Graphene is a two-...
