Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a corrosion-resistant and impact-resistant coating. Background technique [0002] With the continuous development of industrial technology and the use of metal materials more and more widely, the corrosion of metal and its components has spread to all fields of the national economy, causing huge losses to human society. In order to reduce the loss of corrosion, people have taken many protective measures, but so far the most common, economical and practical protective measures are paint protection. Among various anti-corrosion technologies, the anti-corrosion technology of paint is the most widely used. It is widely used due to the characteristics of simple construction, economical application, and not being restricted by equipment area and shape. Among the many types of coatings, epoxy resin occupies an important position in anti-corrosion coatings. It is widely used as a coati...
