Problems solved by technology

[0003] However, most of the current epoxy iron red primers have harmful substances such as the volatilization of organic solvents. At the same time, the particle aggregation of epoxy iron red is serious, and the primer cannot quickly form a uniform thin bottom layer on the surface. Lead to agglomeration phenomenon in the later stage of paint coating, which affects the use of products

Abstract

The invention discloses a decorative corrosion-resistant organic silicon modified epoxy iron oxide red primer which comprises a component A, a component B and a component C. The component A is composed of an epoxy modified acrylic emulsion, a water-based organic silicon resin emulsion, ultrapure water, a dispersing agent, a polyurethane solution, sodium carboxymethyl cellulose and silicone. The component B is prepared from ferric oxide, mica powder, talcum powder, polyvinyl pyrrolidone and silicone oil; the component C is prepared from ternary polycarboxylic acid, thiobacillus ferrooxidans fermentation liquor and seaweed gel; the invention also provides a production process of the decorative corrosion-resistant organic silicon modified epoxy iron oxide red primer. The production process comprises the following steps: S1, preparing atomized liquid drops of the component A substance and the component C substance; S2, preparing a rough epoxy iron oxide red primer; and S3, preparing a decorative corrosion-resistant epoxy iron oxide red primer. The invention has the following beneficial effects: through the component A, the component B and the component C, the component A and the component C are mixed firstly, so that particles of the component B can be fully and uniformly distributed in a mixed solution, and uniform film formation is realized.

Description

technical field [0001] The invention relates to the technical field of paint preparation, in particular to a decorative and corrosion-resistant organosilicon-modified epoxy iron red primer and a production process thereof. Background technique [0002] The primer is the first layer of the paint system, which is used to improve the adhesion of the topcoat, increase the fullness of the topcoat, provide alkali resistance, and provide anti-corrosion functions. At the same time, it can ensure the uniform adsorption of the topcoat and make the paint system play its best good effect. At present, metal products such as iron and steel need to consider the corrosion environment of iron and steel metal products, and iron red is generally used as a primer for coating, so as to achieve the corrosion resistance of iron red, and at the same time increase the organic matter of epoxy to enhance Adhesion and corrosion resistance. [0003] However, most of the current epoxy iron red primers ...
