A kind of anticorrosion coating and preparation method of adding graphene composite material

Abstract

The invention belongs to the field of anticorrosion paint preparation, and in particular relates to an anticorrosion paint added with a graphene / zinc composite material and a preparation method thereof. The anti-corrosion coating is composed of the following components (by weight): 20-90% of polyurethane, 5-15% of graphene / zinc composite material, 1-10% of colored pigment, 5-10% of filler, and 0.1-10% of dispersant 3%, wetting agent 0.1-3%, thickener 0.1-3%, leveling agent 0.1-1%, defoamer 0.1-1%, bactericide 0.1-1%, water 1-35%. The anticorrosion paint prepared by the invention has excellent anticorrosion effect, is harmless to the environment, has a simple process and is easy for industrialized production.

Description

technical field

[0001] The invention belongs to the field of anticorrosion paint preparation, and in particular relates to an anticorrosion paint added with a graphene / zinc composite material and a preparation method thereof. Background technique

[0002] In recent years, with the rapid development of the country and the rapid construction of cities, a large number of metal materials have been used in infrastructure, energy, chemical industry, construction, transportation and other fields, and the ensuing metal corrosion has become more and more serious. It has brought a lot of inconvenience to people's work and life, and caused huge losses to the national economy. However, traditional anti-corrosion coatings have problems such as large environmental pollution, single anti-corrosion effect, and poor anti-corrosion effect, which make them unable to meet the needs of industry development. Therefore, it is imperative to develop a new type of high-efficiency anti-corrosion coati...
