Graphene natural rubber mountaineering shoe sole composite foaming material and preparation method thereof

Abstract

The invention discloses a graphene natural rubber mountaineering shoe sole composite foaming material and a preparation method thereof. The graphene natural rubber mountaineering shoe sole composite foaming material comprises the following raw materials in parts by weight: 60 to 70 parts of natural rubber, 12 to 18 parts of butadiene rubber, 13 to 17 parts of ethylene propylene diene monomer, 4 to 6 parts of white carbon black, 1.6 to 2.0 parts of graphene, 1.4 to 1.7 parts of zinc oxide, 3 to 4 parts of a heat stabilizer, 1.8 to 2.2 parts of a cross-linking agent, 3.5 to 5 parts of a flow promoter and 2 to 2.6 parts of a foaming agent. The graphene natural rubber mountaineering shoe sole composite foaming material is low in density and ultralight; the wear-resisting property is excellent, the tensile strength is high, the mechanical property is good, and the durability is good; and in addition, the non-slip coefficient (dry type non-slip and wet type non-slip) is high, and the non-slip effect is good.

Description

[0001] The present invention is a divisional application of an invention patent application with the application number 202010039700.7, the application date is January 15, 2020, and the title is "Graphene Natural Rubber Polymer Mountaineering Shoe Sole Composite Foaming Material and Its Preparation Method". technical field [0002] The invention relates to the technical field of polymer composite foaming materials, in particular to a graphene natural rubber mountaineering shoe sole composite foaming material and a preparation method thereof. Background technique [0003] Present various soles are mostly made of EVA or rubber material, and the cost is relatively controllable, and properties such as elasticity and hardness can be adjusted as required, which has basically met people's requirements. [0004] Natural rubber is the variety with the best coordination of physical and mechanical properties and process performance among rubber materials. It has been widely used in dail...

AI Technical Summary

Problems solved by technology

[0007] 1. The wear resistance is poor. When used as a climbing shoe sole material, it is easy to wear and tear, resulting in damage and poor durability;

[0008] 2. After foaming, the tensile strength is greatly reduced, the mechanical properties are poor, and the comprehensive performance is poor; or the degree of foaming is low, and it does not have good portability;

[0009] 3. Poor anti-slip effect
