Problems solved by technology

[0002] The corrosion resistance of metals is usually determined by the properties of the metal material itself. In the prior art, the method of making alloys is usually used to improve the corrosion resistance of materials. However, in some industries such as the shipbuilding industry, the use environment of metal materials is quite extreme. In order to further reduce the service life of metal, a waterproof paint for metal is required

Abstract

The invention relates to waterproof paint for metal. The waterproof paint is prepared by polyurethane resin, epoxidized soybean oil, a coupling agent, an antifoaming agent, a leveling agent, hard barium, zinc oxide, calcium silicate, nanoscale titanium oxide, nanoscale activated carbon, filler and a solvent. Experiments show that the waterproof paint is better in waterproof ability as compared with a comparison product. In addition, the waterproof paint has the advantages that the waterproof paint is extremely long in service life, a paint film can be prevented from falling off in 2-3 years under normal conditions, paint film maintaining cost is lowered greatly, and the waterproof paint is worthy of popularization and application.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a waterproof paint for metal. Background technique [0002] The corrosion resistance of metals is usually determined by the properties of the metal material itself. In the prior art, the method of making alloys is usually used to improve the corrosion resistance of materials. However, in some industries such as the shipbuilding industry, the use environment of metal materials is quite extreme. In order to further reduce the service life of metal, a kind of waterproof paint for metal is needed. Contents of the invention [0003] In order to solve the above problems, the present invention provides a waterproof paint for metal. [0004] The present invention is realized through the following technical solutions: [0005] A kind of waterproof paint for metal, in parts by mass, specifically made from the following components: 50-60 parts of polyurethane resin, 5-8 par...
