Technical Field

Background
Heavy-duty Coating refers to a type of anticorrosive Coating that can be applied in a relatively harsh corrosive environment compared to conventional anticorrosive coatings and has a longer protection period than conventional anticorrosive coatings, i.e., a long-lasting anticorrosive life. For example, heavy duty anticorrosive coatings can be used in chemical industry atmosphere and marine environment for more than 10 years or 15 years, and can be used for more than 5 years even in acid, alkali, salt and solvent media under certain temperature conditions.
Cold spray zinc is a high-performance heavy-duty anticorrosive coating which is more and more widely applied in recent years, can replace hot galvanizing, can achieve the same anticorrosive effect as the hot galvanizing by normal temperature spray coating, and avoids the defects of high pollution and high energy consumption in hot galvanizing and hot spray zinc construction. However, cold spray zinc has some disadvantages in application, the content of zinc powder in a cold spray zinc dry film reaches more than 95%, the resin content is low, and the zinc powder is granular metal and has gaps among arrangement, so that the sealing performance of a zinc coating is poor. If the content of zinc powder in cold-sprayed zinc is reduced and the content of resin is increased, although the compactness is better, the cathodic protection effect is influenced, the corrosion resistance is finally influenced, and the effects of hot galvanizing and hot zinc spraying cannot be achieved. Meanwhile, cold spray zinc has poor adhesion due to low resin content, and a paint film is easy to crack when the single-layer thickness exceeds a certain thickness.
In the prior art, in order to solve the problem, a sealing agent is generally coated on the cold galvanizing surface so as to achieve an ideal anticorrosion effect, but the operation steps are complicated, a solvent in the sealing agent is easy to infiltrate and bite the lower cold galvanizing coating, the adhesive force of the coating is easy to reduce, the defects of paint film cracking and falling can be generated in serious cases, meanwhile, strict requirements on the construction process and film thickness control are met, and the field construction is not easy to control.
