Problems solved by technology

Water-based epoxy resin has the advantages of excellent chemical resistance, good adhesion, fast curing rate, etc., but it is easy to age and yellow, so it is not suitable for bottom-surface-in-one coatings; water-based acrylic resin has good anti-ultraviolet Film properties, can effectively make up for the shortcomings of water-based epoxy coatings with insufficient weather resistance

Abstract

The invention discloses a waterborne acrylic acid modified epoxy basalt scale anticorrosive paint. The waterborne acrylic acid modified epoxy basalt scale anticorrosive paint is composed of a component A and a component B, wherein the component A is composed of, by weight part, 30-65 parts of waterborne acrylic acid modified epoxy emulsion, 10-30 parts of basalt scales, 5-10 parts of aluminum tripolyphosphate, 0.1-1 part of defoamer, 0.1-1 part of flatting agent, 0.3-2 parts of dispersant, 0.3-1.5 parts of anti-flash rust agent and 10-50 parts of deionized water; the component B is composed ofwaterborne isocyanate curing agent; the component A and the component B are compounded at a weight ratio of 100:(5-20). The basalt scales serving as a pigment filler are higher in acid-base resistance, thermal resistance and thermal deformation resistance compared with common glass scales and accordingly enhance the comprehensive performance of coatings. The waterborne acrylic acid modified epoxybasalt scale anticorrosive paint retains the advantages of good chemical resistance, strong adhesive force and excellent anticorrosion performance of epoxy resin and has the advantages of high hardness and good weather resistance, thereby being particularly applied to corrosion prevention primer-finishing combined steel structures.

Description

technical field [0001] The invention specifically relates to a water-based acrylic modified epoxy basalt scale anticorrosion coating, which belongs to the technical field of coatings. Background technique [0002] According to relevant statistics, the annual economic loss caused by corrosion in my country is as high as 1.2 trillion yuan, far exceeding the total annual GDP of most provinces and cities. In this regard, people have taken many measures, such as electrochemical protection, corrosive medium treatment, coating protection, etc., but so far, the most economical, effective and generally applicable method is to paint various types of coatings on the metal surface to prevent or slow down corrosion. [0003] Most of the traditional oil-based paints need to use various organic substances as solvents. The content of volatile organic components is high, which will be discharged into the air during use, causing environmental pollution, seriously affecting people's physical a...
