Description

technical field [0001] The invention relates to the technical field of anti-corrosion coatings, in particular to an impact-resistant and cold-resistant anti-corrosion coating. Background technique [0002] With the rapid development of economy and society, metal materials are used more and more widely, and the corrosion of metal and its components has spread to all fields of national economy. There are many anti-corrosion measures, but so far the most common, economical and practical protection measures are anti-corrosion coatings. Anti-corrosion coatings are widely used because of their simple construction, economical applicability, and freedom from equipment area and shape constraints. Among the many types of coatings, epoxy resin plays an important role in anti-corrosion coatings. It is widely used as a coating material for metal anti-corrosion. It has excellent adhesion and water resistance. Its output is increasing day by day, and new varieties are coming in succession....
