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 there have been no reports on the use of salicylaldehyde and some metal ion complexes in marine anti-biofouling coatings

Abstract

The invention provides a silicone acrylic resin based ocean anti-fouling paint. The paint is characterized in that salicylic aldehyde and quaternary ammonium salt modified silicone acrylic resin serves as a coating of a film-forming substance; the salicylic aldehyde and quaternary ammonium salt modified silicone acrylic resin is obtained by reacting silicone acrylic resin of which the macromolecular side chain contains a tertiary amine group with 5-chloromethyl methyl ether salicylic aldehyde. The silicone acrylic resin based seawater anti-fouling paint has the antiseptic antibacterial synergy and can effectively lower the drug resistance of bacteria microorganism; and the salicylic aldehyde and quaternary ammonium salt modified silicone acrylic resin serves as the film forming substance in seawater and can chelate and adsorb copper ions or nickel ions in seawater and generates new antiseptic antibacterial efficiency.

Description

technical field [0001] The invention relates to a silicone-acrylic resin-based marine antifouling coating, in particular to a silicone-acrylic resin coating modified by salicylaldehyde and a quaternary ammonium salt, which has the function of preventing marine biofouling and belongs to the field of functional materials. technical background [0002] People have been constantly exploring anti-biofouling technologies and methods for marine vessels and marine facilities in seawater. At present, the simple and 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 to prevent marine organisms from adhering. Adding biocidal, antibacterial and antifouling agents is a widely used, simple and low-cost method for applying antifouling coatings. ...
