Environment-friendly anti-corrosive paint

Abstract

The invention discloses an environment-friendly anti-corrosive paint. The paint is prepared from the following ingredients as raw materials in parts by weight: 80-90 parts of waterborne polyurethane emulsion, 60-78 parts of polyacrylate emulsion, 45-52 parts of polyacrylic ester emulsion, 25-32 parts of toluene diisocynate, 8-13 parts of a pigment, 1.0-3.2 parts of organic tin clathrate, 0.9-1.5 parts of a stabilizer, 1.2-2.3 parts of a thickening agent, 2.3-4.2 parts of a flatting agent and 5.0-10.9 parts of a filler; a binding agent is prepared from the following ingredients in parts by weight: 1.0-2.0 parts of sodium alginate, 2.0-3.0 parts of guar gum and 2.0-3.0 parts of carrageenan; the waterborne polyurethane emulsion, the polyacrylate emulsion and the polyacrylic ester emulsion serve as main raw materials, so that the paint has excellent covering power and strong adhesive power; by adding the organic tin clathrate, the dry adhesive force of a paint material is conducive to being improved, and when the environment-friendly anti-corrosive paint applied onto a surface layer of equipment is exposed to wind and rain, paint falling cannot happen so that the environment-friendly anti-corrosive paint has stable quality; the hollow microspheres improve the surface smoothness and rigidity of the environment-friendly anti-corrosive paint, and the scratch resistance of the environment-friendly anti-corrosive paint is improved.

Description

Technical field [0001] The invention relates to the technical field of coatings, in particular to an environmentally friendly anticorrosive coating. Background technique [0002] Many environmental protection equipment in the prior art have been exposed to wind and rain for a long time, and require extremely high anti-corrosion performance on the surface of the equipment; there are many methods to prevent corrosion of metal materials, such as the use of corrosion-resistant metal materials, cathodic protection, corrosion inhibitors and Metal protective coatings. Practice has proved that among the above metal anti-corrosion methods, the use of environmentally friendly anti-corrosion coatings to protect easily corrosive metal materials is the most economical, effective and widely used anti-corrosion method. Conventional anti-corrosion coatings can prevent corrosion of metals under normal conditions to increase the service life of non-ferrous metals; however, conventional anti-corros...

AI Technical Summary

Problems solved by technology

Conventional anti-corrosion coatings play an anti-corrosion effect on metals under normal conditions to improve the service life of non-ferrous metals; however, conventional anti-corrosion coatings cannot be applied in relatively harsh corrosive environments, and it is difficult to meet the needs of users for coating anti-corrosion capabilities , the surface of the environmental protection equipment under the anti-corrosion coating will fall off after a period of use, and the anti-corrosion performance is poor
