Since the advent of water-based anti-rust paint, the demand for water-based anti-rust paint in my country has been increasing at a rate of more than 10% every year. At present, although there are water-based anti-rust paints with various formulations, the existing water-based anti-rust paint is due to its own factors. In terms of anti-rust performance, anti-salt water, and anti-salt spray performance, there are still some deficiencies. Therefore, how to ensure the anti-rust performance, anti-salt water, and anti-salt spray performance of water-based rust-resistant anti-corrosion coatings is the direction of our research.

Abstract
The invention discloses a water-based antirust paint and a preparation method thereof. The water-based antirust paint comprises the following active ingredients in parts by weight: 36.0-72.0 parts of water-based resin, 0.01-0.80 part of a dispersing agent, 3.0-10.0 parts of red ferric oxide powder, 7.0-20.0 parts of PAST-2 biological anti-corrosion pigment, 5.0-10.0 parts of barium sulfate, 4.0-9.0 parts of sericite, 10.0-20.0 parts of deionized water, 0.2-0.5 part of a composite type corrosion inhibitor, 0.05-0.1 part of composite anti-corrosion mould-proof bactericide, and 0.05-0.1 part of a defoaming agent. The preparation method comprises the following steps of adding the dispersing agent, composite anti-corrosion mould-proof bactericide, composite type corrosion inhibitor and the defoaming agent into the deionized water, stirring and dissolving, then adding red ferric oxide powder, PAST-2 biological anti-corrosion pigment, barium sulfate and sericite, and stirring at high speed and dispersing to obtain color paste; carrying out ball milling on the color paste, then adding the water-based resin, and evenly dispersing to obtain the water-based antirust paint.
Description
technical field [0001] The invention relates to the technical field of industrial coatings, in particular to a water-based antirust paint with rust. Background technique [0002] The simplest and most effective way to prevent corrosion on the surface of steel structures is to use paint to protect them. Because oil-based paint contains a large amount of organic solvents, it causes extremely serious pollution to the environment. Therefore, water-based antirust paint is one of the research directions of the paint industry in various countries. Since the advent of water-based anti-rust paint, the demand for water-based anti-rust paint in my country has been increasing at a rate of more than 10% every year. At present, although there are water-based anti-rust paints with various formulations, the existing water-based anti-rust paint is due to its own factors. There are still some deficiencies in terms of anti-rust performance, anti-salt water, and anti-salt spray performance. The...
