Description

technical field [0001] The invention relates to the field of industrial anticorrosion paints, in particular to a special water paint with high anticorrosion and high weather resistance for metal components and a manufacturing method thereof. Background technique [0002] With the increasing shortage of natural resources, people's demand for resources is increasing day by day. In today's society, the application of steel structures is becoming more and more extensive, and the requirements for high anti-corrosion and high weather resistance on the surface of steel structures are becoming more and more important. Due to the low surface energy of steel structures, there are certain difficulties in the adhesion of coatings on the surface, so most of the coatings used on the surface of steel structures are solvent-based coatings. A large proportion of solvent-based coatings are volatile solvents, which volatilize into the atmosphere after coating, causing a great degree of air po...
