Description
Technical Field
The invention relates to the technical field of coatings, in particular to a high-environmental-protection water-based metal protective paint capable of being constructed outdoors and a preparation method thereof.
Background
The metal is easily affected by illumination, rain wash, cold and hot stimulation and the like after being exposed in the external environment for a long time, is very easy to rust, and affects the service life of metal products. The most effective way to solve this problem is to apply a protective paint to the metal surface. Most of the traditional metallic paints are solvent-based metallic paints, which contain a large amount of organic solvents, and the organic solvents volatilize when in use, thereby causing serious pollution to the environment. In recent years, waterborne coatings have gradually replaced traditional solvent-based coatings, and the yield of solvent-based coatings in many developed countries has exceeded 50% of the total coating yield.
The traditional water-based alkyd resin has the advantages of low price and good molding property, and is widely applied to the preparation of water-based metal paint. However, the conventional alkyd resin contains a large amount of ester groups and is easily decomposed in water, resulting in reduced product performance, reduced viscosity and poor film-forming property. In addition, the coating film has poor weather resistance, is not easy to form a film under high temperature conditions during outdoor construction, and is easy to deteriorate, embrittle and fall off outdoors. In addition, when the temperature is lower (-10 ℃), the viscosity of the alkyd resin is too high, which affects the outdoor spraying construction in some areas. In addition, the existing water-based paint for metal devices or equipment has high requirement on the flatness of the equipment before spraying, and uneven spraying is easy to occur on the convex or concave parts of irregular devices, so that the use of the water-based alkyd resin is limited.
Therefore, the development of the high-adaptability water-based alkyd resin which can be constructed under the severe outdoor conditions of high temperature or low temperature and can be quickly dried to form a film is urgently needed; meanwhile, the paint has excellent adhesive force and uniform dispersity on irregular parts of metal device equipment, and can best play a role in protecting metal by the waterborne alkyd resin.
