Abstract

The invention provides an epoxy polyurethane zinc phosphorus anti-corrosive paint, the components of the anti-corrosive paint are as follows: a first component which comprises aliphatics solidifying agent and environmental protective solvent, a second component which comprises macromolecular epoxy resin, anti-corrosive pigment I, anti-corrosive painting II, the environmental protective solvent, dispersing agent, anti-foaming agent, leveling agent and filler. When the the first component and the second component are used, the mixed ratio of the weight of the first component and the second component is 1:5. The invention also discloses a preparation method of the epoxy polyurethane zinc phosphorus anti-corrosive paint. The epoxy polyurethane zinc phosphorus anti-corrosive paint has the advantages that the epoxy polyurethane zinc phosphorus anti-corrosive paint of the invention adopts macromolecular epoxy resin and adipose polyisocyanate reaction, the adhesive force of the paint film is good, the drying speed is quick, and the thermal-resistant temperature of the paint reaches over 150 DEG C, because the tetroxy chromate and xinc phosphate compound anti-corrosive high-efficient pigment are adopted, the anti-corrosive paint has the long-time anti-corrosive performance; the surface treatment of the backing material is not required strictly, the construction is convenient, and the environmental protective solvent can not cause pollution to the environment; the paint film has good acid resistance and alkali resistance and solvent resistance; the preparation method is simple, and the large-scale production is easy.

Description

technical field [0001] The invention relates to a paint and a preparation method thereof, in particular to an epoxy polyurethane zinc phosphorus anticorrosion paint and a preparation method thereof. Background technique [0002] Material corrosion is the great enemy of human beings, and it brings huge economic losses to all countries in the world. Therefore, it will be of great significance to study high-performance and effective anti-corrosion materials. [0003] There are many kinds of anti-corrosion paints at home and abroad, mainly alkyd paints, chlorinated rubber paints and chlorosulfonated polyethylene paints. Alkyd coatings were used earlier, and chlorosulfonated polyethylene coatings and chlorinated rubber coatings were popularized in recent years, but the weather resistance of these coatings is not ideal. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an epoxy polyurethane zinc phosphorus anti-corrosio...
