Description

Technical Field

[0001] The utility model relates to the technical field of paint coatings, in particular to a high-performance self-polishing antifouling paint coating structure. Background Art

[0002] The primary problem encountered by ships when sailing in the sea is the attachment and fouling of marine organisms to the bottom of the ship. More than 200,000 species of marine organisms have been initially discovered. Some organisms grow by attaching to fixed objects. The bottom of the ship below the waterline is the main base for biological attachment. The attachment of marine organisms brings great harm to the navigation of ships, and they will increase the roughness of the bottom of the ship, reduce the speed, and increase fuel consumption. Mucus fouling can increase the navigation resistance by up to 9%; waterweed fouling can increase the navigation resistance by up to 19%; shell fouling can increase the navigation resistance by up to 33%-84%. According to statistics, half of the fuel costs are spent on compensating for the deceleration caused by the failure of antifouling paint each year, and a large amount of dockage and labor fees are spent on re-coating anti-rust and antifouling paint. Therefore, the development of high-performance self-polishing antifouling coatings has always been the most important topic in the field of ship coating research. An antifouling paint coating is needed that can achieve the defouling function of the bottom of the ship better and with high performance. In view of this, the inventors have proposed a high-performance self-polishing antifouling paint coating structure to solve the above problems. Compared with ordinary antifouling paint, it can more effectively improve the performance of antifouling paint, extend the service life of the ship bottom, reduce maintenance cycles, and reduce maintenance costs.

[0003] In order to solve the problem that dirt and marine organisms often adhere to the bottom of the ship, causing the bottom of the ship to be rough, affecting the speed and increasing fuel consumption, a Chinese patent application, publication number: CN101550305A, discloses a long-lasting self-polishing antifouling paint. The invention is composed of acrylic copper resin, composite antifouling agent, pigment, filler, anti-settling agent, and solvent. The invention can effectively prevent marine organisms from fouling the bottom of the ship within 3-5 years, does not contain internationally banned organic tin (TBT) and DDT toxic materials, has environmental protection characteristics, is easy to construct, can maintain the speed of the ship without being affected, and saves fuel.

[0004] This solution still has some shortcomings in application. In addition to the outermost layer of antifouling paint on the bottom of the ship, primer and anti-rust paint are also applied inward. It is critical to achieve effective adhesion between the antifouling paint, primer and anti-rust paint. If the adhesion is poor, the antifouling paint will easily fall off, which will directly affect the antifouling effect. In addition, the antifouling paint is in the outermost layer and will become thinner and thinner as it reacts with seawater. It is necessary to be able to maintain the antifouling paint when it is almost exhausted to achieve the maximum use of the antifouling paint. Therefore, it is necessary to improve the coating structure of the antifouling paint so that it can be better bonded with other paints and used in conjunction with them, while also having a high-performance antifouling effect.

[0018] The specific implementation of the present utility model will be further described below with reference to the accompanying drawings.

[0019] like Figures 1 to 3 As shown, a high-performance self-polishing antifouling paint coating structure comprises a paint surface, wherein the paint surface comprises a primer 1, an anti-rust paint 2 and a self-polishing antifouling paint 3 from the inside to the outside, a mesh 4 is arranged between the anti-rust paint 2 and the self-polishing antifouling paint 3, the primer 1 is an epoxy zinc-rich primer, the anti-rust paint 2 is a zinc phosphate anti-rust paint, and the self-polishing antifouling paint 3 uses acrylate zinc resin as a base material, and cuprous oxide, an organic antifouling agent, an anti-settling agent and a color filler are mixed in the base material.

[0020] Furthermore, the thickness ratios of the primer 1, the anti-rust paint 2 and the self-polishing antifouling paint 3 are 4:4:2 respectively.

[0021] Furthermore, the pull net 4 is a wire mesh, and the wire mesh adopts a vertical and horizontal cross structure.

[0025] [Example]

[0026] First, the primer 1 is applied to the surface to be painted, and the anti-rust paint 2 is applied after the primer 1 is dried.
