Description

technical field [0001] The invention relates to the technical field of water-based coatings, in particular to a high-strength impact-resistant and corrosion-resistant mechanical coating. Background technique [0002] With the continuous development of industrial technology, machinery is used more and more widely, and the corrosion of its components has become increasingly prominent, which has brought great hidden dangers to safe production. 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. At present, metal coating technology has problems such as short corrosion resistance, weak impact resistance...
