Graphene-rod-like aluminum-doped zinc oxide antistatic coating and preparation method thereof

Abstract

The invention belongs to the technical field of production of antistatic coating and in particular relates to a graphene-rod-like aluminum-doped zinc oxide antistatic coating and a preparation method thereof. The antistatic coating comprises the following components in parts by weight: 60-85 parts of waterborne acrylic emulsion, 0.5-1.0 part of antifoaming agent, 1-2.5 parts of flatting agent, 1-3.5 parts of thickening agent, 2-3 parts of graphene, 7.15-31.25 parts of rod-like aluminum-doped zinc oxide dispersion and 0.5-30 parts of deionized water. Flake graphene and the rod-like aluminum-doped zinc oxide can form a three-dimensional conductive network in a coating system, so that the conductive performance of the coating can be enhanced, and compared with a coating formed by singly graphene or aluminum-doped zinc oxide, the graphene-rod-like aluminum-doped zinc oxide antistatic coating has the advantages that the same conductive effect is achieved, and the addition amount is obviously reduced. Moreover, due to a special structure, the mechanical property of the coating can be obviously enhanced.

Description

technical field [0001] The invention belongs to the technical field of antistatic paint production, in particular to a graphene-rod-shaped aluminum-doped zinc oxide antistatic paint and a preparation method thereof. Background technique [0002] Antistatic coatings refer to a type of special functional coatings that are applied on non-conductive substrates and have the ability to conduct current and eliminate accumulated static charges. They are mainly composed of conductive fillers, resins, thinners and additives. In recent years, with the rapid development of science and technology, antistatic coatings have been applied in various military and civilian industrial fields such as electronics, electrical appliances, aviation, chemicals, and printing. [0003] Graphene is a carbonaceous material with a two-dimensional sheet structure (<1nm) that has been newly discovered in recent years and has a two-dimensional sheet structure (<1nm). It has high strength and good condu...
