Abstract

The present invention discloses a preparation method for an environmental-friendly metallic anti-corrosion coating which is characterized in comprising the following components in percentage by weight: 80% of an aqueous emulsion, 10% of deionized water, 2% of nano paste, 8% of a coalescing agent, and a proper amount of a flash and rust inhibitor, a leveling agent, a wetting agent, a defoaming agent and a rheologic modifier. The preparation method comprises: adding water into the aqueous emulsion; adding the nano paste after stirring the mixture uniformly; adding the wetting agent, the defoaming agent, the leveling agent sequentially in 30 minutes, and finally adding the rheologic modifier; and filtering to obtain the coating. According to the coating disclosed by the present invention, solvent-resistant performance of a coating film is improved by adding nanomaterials to the anti-corrosion painting, and the coating is free of any harmful effects on a human body and the environment in a manufacturing process and after use, so that the coating is a green and environmental-friendly product.

Description

Technical field [0001] The invention relates to a preparation method of an environment-friendly metal anti-corrosion coating. The anti-corrosion coating has a rust transfer function and can be directly used on steel surfaces that have only undergone simple rust removal treatment, which greatly simplifies the steps of anti-corrosion construction of steel structures. At the same time, the harm to the environment is reduced. Background technique [0002] Compared with oily anti-corrosive paint, environmentally friendly anti-corrosive paint has the characteristics of not containing harmful ingredients such as benzene and formaldehyde, and there will be no such chemical substances harmful to human health and the environment during production and processing. , To avoid serious environmental pollution and ecological damage, so in today's increasingly prominent environmental issues, the development and maturity of environmentally friendly anti-rust paint is an inevitable trend. Therefor...
