Problems solved by technology

The disadvantages of this technology are: the production process is complicated, and it needs to be heated. Although it dries quickly, if it is acrylic resin, it will have a strong smell and high VOC content; trace problem
The performance of this product is good, but it smells, the production process is complicated, and the cost is the highest, which is difficult for customers to accept under the current situation

Abstract

The invention discloses waterborne antirust primer, comprising component A and component B; the component A is made from, by weight, 15-20% of deionized water, 0.1-0.4% of a humidifying agent, 0.1-0.3% of a dispersant, 0-0.5% of a defoaming agent, 32-39% of an antirust material, 5-10% of a filling material, 40-45% of styrene-acrylic emulsion, 0.3-0.8% of a leveling wetting agent, 0.1-0.3% of an associating thickener, 0-1% of a film-forming aid, 0-0.5% of a preservative; the component B is made from, by weight, 70-80% of silicates, 0-10% of silica sol, 2-4% of silane coupling agent, and 12-17%of deionized water. The properties of waterborne antirust coatings are satisfied, and the waterborne antirust coatings have good storage stability.

Description

technical field [0001] The invention belongs to the technical field of industrial anticorrosion coatings, and relates to a water-based anticorrosion industrial coating, that is, a primer. Background technique [0002] In recent years, the country's requirements for VOC emissions have become more and more stringent, and industrial coatings have begun to develop in the direction of water-based, high-solid content, and powder coating light-curing, especially water-based coatings. It is mature, but it has already begun to promote it in the market in an all-round way. The purpose is to have a market when the national policy is one-size-fits-all for solvent-based coatings. Through years of research on water-based anti-corrosion coatings and purchasing and collecting water-based anti-corrosion coatings on the market for analysis, testing and comparison, it is found that: a water-based anti-rust primer is really prepared, with low VOC emissions, and its performance is comparable to ...
