Abstract

A preparation method of completely peeled oxidation graphene / rubber nanometer composite material adopts combination of emulsion compounding and flocculation processes or combination of emulsion compounding and spraying drying processes. The preparation method retains the phase state structure of the oxidation grapheme / rubber composite emulation in the liquid state and obtains the phase-state structure which is highly dispersed, highly peeled and dispersed in nanometer scale dispersion. Simultaneously, substances capable of acting with generating ionic bond effect or chemical bond effect with an oxidation graphene surface functional group are added into the oxidation graphene / hydrosol to serve as an interface agent, thereby improving interface combination effect of oxidation graphene and rubber. Vulcanized rubber prepared by the composite material of the preparation method through follow-up mixing and vulcanizing has mechanical property such as high tensile strength, stretching stress and tearing strength and is capable of greatly improving abrasion resistance and gas separation performance of the vulcanized rubber. The preparation method is simple, easy, low in cost, apt to industrialization and wide in suitable aspect, saves energy and has better economical and social benefits.

Description

technical field [0001] The present invention relates to a preparation method of graphene oxide / rubber nanocomposite material with high exfoliation, high dispersion and strong interfacial bonding, in particular to the combination of emulsion compounding and flocculation process, or the combination of emulsion compounding and spray drying process to prepare interfacial agent-containing Graphene oxide / rubber nanocomposites. Background technique [0002] In the rubber industry, the largest and most versatile fillers are nano-scale carbon black and white carbon black. Carbon black is the most important reinforcing filler in the rubber industry, but with the dwindling of petroleum resources, the application of the carbon black industry, which is completely dependent on petroleum, is restricted to a certain extent, and there is still environmental pollution in the production and application of carbon black question. The reinforcing performance of silica to rubber is close to that...
