Description

technical field [0001] The invention relates to a graphene-containing water-based acrylic anticorrosion coating and a preparation method thereof, belonging to the technical field of anticorrosion coatings. Background technique [0002] At present, the development of water-based anti-corrosion coatings is relatively rapid, and high-performance anti-corrosion coatings are sought after by the market. However, the vigorous development of water-based anti-corrosion coatings cannot conceal the gap with solvent-based coatings. Especially in the field of light anti-corrosion, a large number of steel structure anti-corrosion, civil anti-corrosion, mechanical anti-corrosion, etc., are limited by raw materials, water-based one-component self-drying anti-corrosion coatings are difficult to meet the demand, and there is still a big gap with solvent-based coatings. These customers are forced to use water-based two-component epoxy primer and water-based topcoat. Although water-based two-c...

However, the vigorous development of water-based anti-corrosion coatings cannot conceal the gap between them and solvent-based coatings.

Especially in the field of light anti-corrosion, a large number of steel structure anti-corrosion, civil anti-corrosion, mechanical anti-corrosion, etc., are limited by raw materials, water-based one-component self-drying anti-corrosion coatings are difficult to meet the demand, and there is still a big gap with solvent-based coatings

These customers are forced to use water-based two-component epoxy primer and water-based topcoat. Although water-based two-component epoxy paint increases the film performance of water-based paint, it has a certain impact on the environmental protection of water-based paint and will increase some organic Volatile (VOC) Emissions and Odors

At the same time, the coating cost of two-component water-based wood paint is at least twice as high as that of single-component water-based wood paint

[0003] Commonly used water-based acrylic anticorrosive coatings have many advantages such as weather resistance, heat resistance and low cost, but there are still some problems that cannot be ignored. For example, in order to make acrylic resins water-soluble, hydrophilic groups must be introduced in the preparation process As a result, the water resistance and corrosion resistance of the coating film will deteriorate, the drying speed will be slow, and the hardness of the coating film will also decrease. The cost is high and the performance is low. Usually, the content of volatile organic compounds (VOC) in solvent-based coatings High, will cause air pollution
