Embodiment 1

[0026] According to the following formula, the graphene / ABS composite material was prepared by bulk method in situ polymerization: 12 parts of polybutadiene rubber, 66 parts of styrene, 22 parts of acrylonitrile, 0.1 part of benzoyl peroxide, and 15 parts of ethylbenzene Part, 1 part of graphene powder, weighed by weight fraction.

[0027] Cut the polybutadiene rubber into pieces and dissolve it in ethylbenzene, add styrene, acrylonitrile monomer and graphene powder, and use mechanical stirring to make a rubber solution. Slowly raise the temperature to 120°C, add benzoyl peroxide to carry out polymerization. After the material reaches a conversion rate of about 75%, the material coming out of the polymerization tank is sent to the first devolatilizer with a gear pump, and flash evaporated at a pressure of 0.196 MPa to remove most of the volatilization of acrylonitrile and some styrene monomers, ethylbenzene, etc. components. After being heated to 240°C by a tubular heater, i...

Abstract

The invention belongs to the technical field of materials and particularly relates to a method for preparing a graphene / ABS (Acrylonitrile Butadiene Styrene) composite material through in-situ bulk polymerization. The method comprises the steps of dissolving rubber into a solvent; adding styrene, an acrylonitrile monomer and graphene; and carrying out bulk polymerization to obtain a graphene / ABS composite material. The method is low in investment, continuous in production, simple in process flow, strong in adaptability, environment-friendly, energy-saving and suitable for industrial production; due to the addition of the graphene, the defect that the impact strength is limited when ABS resin is produced by using a bulk polymerization method can be overcome, and the composite material with improved comprehensive performances can be obtained; the composite material can be widely applied to industries such as automobiles, electronics, electric products, light industry, furniture, textiles and buildings.
