Graphene oxide reinforced water-based plastic coating and preparation method thereof

Abstract

The invention belongs to the technical field of chemical water-based coatings, and especially relates to a graphene oxide-reinforced water-based plastic coating and a preparation method thereof. The graphene oxide-reinforced water-based plastic coating has the characteristics of high hardness, good friction resistance, good fingerprint resistance and good chemical resistance necessary for 3C consumer electronic product coatings. The graphene-modified water-based 3C consumer electronic product shell paint provided by the invention also has a good electromagnetic shielding effect. Monolayer graphene oxide with a single-layer ratio of above 99% is reduced at a high temperature to obtain the graphene-modified water-based 3C consumer electronic product shell paint, the graphene has excellent electrical conductivity, and has a good reflection loss to electromagnetic radiation; ferrite powder is a magnetic material with a very high magnetic permeability, and is a commonly used wave absorbingmaterial, and realizes electromagnetic radiation magnetic dielectric radiation loss, the graphene and ferrite powder synergistically provide a good electromagnetic shielding effect, and the introduction of the graphene improves the heat dissipation property of the coating and further ensures the use safety of the 3C consumer electronic product.

Description

technical field [0001] The invention belongs to the technical field of chemical water-based coatings, and in particular relates to a graphene oxide-enhanced water-based plastic coating and a preparation method thereof. Background technique [0002] Computers, communications and consumer electronics products are called "3C products". In the past ten years, the global consumer electronics market has developed rapidly, and the development and popularization of mobile Internet technology has promoted the use of 3C consumer electronics products on the one hand. Consumers' demand for portable consumer electronics products continues to expand, and is gradually moving toward diversification and customization. Appearance has become the main focus of consumers for 3C consumer electronics products. The corresponding market for protective shells is related to the coatings used. Closely, 3C consumer electronics products have high appearance requirements, which requires a highly flat, uni...
