Problems solved by technology

However, the above-mentioned technology has the defects of single bactericidal and antibacterial effect, expensive raw materials and complicated production technology.
[0004] Professionals have long known that salicylaldehyde and its complexes with some metal ions also have bactericidal and antibacterial effects, and the use of salicylaldehyde in complexes with some metal ions and quaternary ammonium salts for marine antifouling coatings has not yet been reported.

Abstract

The invention provides an ocean antifouling paint which consists of an antifouling type film forming material, a filler, pigments, a silane coupling agent, a flatting agent and a solvent. The antifouling type film forming material is a macromolecule complex prepared by carrying out a chelation reaction on salicylide as well as quaternary ammonium salt modified polyacrylate and antibacterial metal ionic compound as materials. The ocean antifouling paint provided in the invention has the following characteristics: (1) the preparation method of the ocean antifouling paint is simple and feasible, the source of the materials is abundant, and the cost is low; (2) the antifouling type film forming material contains two sterilization and antibacterial materials with different mechanisms, and sterilization and antibacterial synergistic effect is achieved, and the drug resistance of bacterial microorganisms can be effectively reduced.

Description

technical field [0001] The invention relates to a marine antifouling paint and a preparation method thereof, belonging to the field of functional materials. technical background [0002] People have been exploring and researching anti-biofouling technologies and methods for marine vessels and marine facilities in seawater. At present, the most effective way is coating. The so-called anti-fouling principle of coating is the self-purification effect of low surface energy of the coating, so that marine organisms have no adhesion on the surface of the coating; the second is to add biocidal antibacterial and antifouling agents to the coating. Adding biocidal, antibacterial and antifouling agents is a widely used, simple and low-cost method for applying antifouling coatings. The traditional biocidal, antibacterial and antifouling agents are mainly organotin, because it will accumulate in the ocean and affect the growth of marine organisms and the marine food chain, not only serio...
