Abstract

A natural rubber modification method based on a graphene modification technology. The invention belongs to the technical field of natural rubber material modification and particularly relates to a method of employing graphene or a derivative thereof to modify natural rubber through an aqueous-phase dispersion technology. According to the modification method, the graphene or the derivative thereof is homogeneously dispersed in natural rubber through the aqueous-phase dispersion technology to prepare the modified natural rubber. The modified natural rubber is improved by more than 40% in tensile strength and can reach 500% maximumly under an optimum concentration, is reduced by 10-20% in ultimate strain, is increased by 5-30% in elasticity modulus, is increased by 1000 times maximumly in electric-conductivity, is increased by 18-39% in thermal-conductivity, is reduced in air permeability and is increased in compactness.

Description

Technical field [0001] The invention belongs to the technical field of natural rubber material modification, and specifically relates to a method for applying graphene and its derivatives to modify natural rubber by applying water phase dispersion technology. Background technique [0002] Natural rubber has excellent comprehensive properties, such as high wet gel strength and easy vulcanization. The resulting products have excellent elasticity, high strength, large elongation and small creep properties, which are obtained in the chemical industry. Wide range of applications. However, the physical and mechanical properties of natural rubber, such as hardness and tensile strength, cannot meet many practical needs. It is urgent to improve the strength, wear resistance, and anti-aging properties through modification to broaden its application fields. [0003] Nanomaterials have special surface effects, small size effects, quantum size effects, and quantum tunneling effects. The compos...
