Abstract

The invention discloses a graphene-modified natural latex polymer and a modification method thereof. The modification method comprises modifying graphene through a coupling agent, uniformly dispersing the modified functionalized graphene in natural rubber to obtain the graphene-modified natural latex polymer and the modification method solves the problem of nonuniform dispersion of graphene in natural rubber. The graphene-modified natural latex polymer improves mechanical properties by 20-200%, improves barrier properties and blocks various viruses. The modification method of the graphene-modified natural latex polymer utilizes easily available raw materials and easily realizes large scale production. The invention also discloses the graphene-modified natural latex polymer prepared through the modification method.

Description

Technical field [0001] The present invention is a composition technology field of natural rubber, which is specifically a graphene modified natural latex polymer and its modification method. Background technique [0002] Natural rubber has excellent comprehensive performance, the products have excellent elasticity, high strength, large elongation, small extension and smaller creep, etc., and have been widely used in the chemical industry.However, natural rubber cannot meet many practical needs in terms of physical mechanical properties such as pure glue hardness and stretch strength. It is urgently needed to improve its strength, abrasion resistance, anti -aging and other properties, and broaden its application field. [0003] Nano -material has special surface effects, small -sized effects, quantum size effects, and quantum tunnel effects. The composite material shows unique performance of mechanics, heat, optics, and electromagnetic science.In the rubber industry, the composite...
