Problems solved by technology

However, since the coating is mainly used for pipeline anticorrosion, there is no problem that the epoxy resin coating cannot be exposed to light, and it can be predicted based on the prior art and the properties of the epoxy resin that if the coating is used for building anticorrosion coating When layering, the coating on the outer surface contains both epoxy resin and fluorocarbon resin. The weather resistance of the coating will be affected by the presence of epoxy resin, so it still cannot solve the problem that powder coatings containing epoxy resin are not suitable. The problem of anti-corrosion applied to outdoor materials, and the lack of anti-corrosion performance of architectural coatings

Abstract

The invention relates to a heavy anticorrosion super weatherproof powder coating. The heavy anticorrosion super weatherproof powder coating comprises the following components of: an epoxy resin particle system containing epoxy resin and an adaptive curing agent A and a fluorocarbon resin particle system containing fluorocarbon resin and an adaptive curing agent B, wherein the weight part ratio of the epoxy resin particle system to the fluorocarbon resin particle system is (6-4):(4-6). The heavy anticorrosion super weatherproof powder coating provided by the invention has excellent weatherproof and anticorrosion properties and also can realize automatic stratification after once coating is carried out, and construction is simple.

Description

technical field [0001] The invention belongs to the field of powder coatings, and in particular relates to a heavy-duty anti-corrosion super-weather-resistant powder coating and a preparation method and application thereof. Background technique [0002] Heavy-duty anti-corrosion coating is a kind of coating that can be used effectively for a long time in a severe corrosive environment. In order to achieve the purpose of heavy-duty anti-corrosion, on the one hand, it is necessary to thicken the coating, on the other hand, the selection of coating resins and additives, the substrate The requirements for surface treatment, coating construction and maintenance are also very strict. At present, most of the coatings used in heavy-duty anti-corrosion are liquid coatings. However, liquid coatings contain a large amount of organic solvents (most of them contain more than 50% of solvents), and they must be completely volatilized in the coating process before they can form a film. This...
