preparation example Construction

[0048] The preparation method of the modified graphene adopted in the following examples is as follows:

[0049] Step i: Use the Hummers method to prepare graphene oxide. Specifically, mix 2g of graphite, 1gNaNO3, and 46ml of concentrated sulfuric acid with a mass concentration of 98% in an ice-water bath, stir for 30 minutes, make it fully mixed, and weigh 6g of KMnO4 After adding the above mixed solution for 2 hours and continuing to stir for 2 hours, move it into a warm water bath at 35°C and continue stirring for 30 minutes; then slowly add 92ml of distilled water, and control the reaction solution at about 98°C for 15 minutes, then add an appropriate amount of 30% H2O2 to remove excess Then add 140ml of distilled water to dilute, filter while hot, and wash with 0.01mol / L HCl, absolute ethanol and deionized water successively until there is no SO in the filtrate 4 2- Until it exists, graphite oxide is obtained; then graphite oxide is ultrasonically dispersed in water to o...

Abstract

The invention relates to an antistatic master batch for plastics and a plastic film containing the antistatic master batch, the antistatic master batch comprises a resin carrier and a conductive active component compounded with the resin carrier, the resin carrier is an ethylene-vinyl acetate copolymer, the conductive active component comprises poly (N-methylpyrrole) gel loaded with modified graphene and polyethylene glycol in a mass ratio of 1: (1-4). A plastic film material prepared from the antistatic master batch not only has good dimensional stability, excellent heat resistance and chemical corrosion resistance, but also meets the environment-friendly requirement, and has an efficient, lasting and stable antistatic effect, and the obtained product has good surface glossiness and excellent mechanical properties. And the method has a good application prospect in the development of the high polymer material technology industry.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to an antistatic master batch for plastics and a plastic film containing the antistatic master batch. Background technique [0002] Nowadays, plastic products have been widely used in all aspects of people's production and life. Due to their good characteristics such as light weight, easy processing, high electrical insulation, and design according to the application, they have also become important processing materials for electrical products. However, due to the high insulation of plastic itself, in practical applications, a large amount of charge is often generated due to friction and accumulates on the surface of the plastic, and it is difficult to completely eliminate it, which will not only limit the application of plastics in the field of electrical products , and there will be a very large security risk. For example, polypropylene resin, as an engineer...
