Abstract

The invention discloses a waterproof antibacterial marine coating. Raw materials of the marine coating comprise the following ingredients, by weight, 45-60 parts of a fluorine-silicon modified acrylic emulsion, 30-45 parts of a vinyl acetate emulsion, 4-10 parts of polypropylene fiber, 5-15 parts of silicon nitride, 1-5 parts of graphite oxide, 20-35 parts of liquid petroleum resin, 1-3 parts of ethylene dimethacrylate, 2-5 parts of 3-methacryloxy propyl trimethoxy silane, 0.5-2 parts of tri-n-butyl phosphate, 3-8 parts of oxidized starch, 5-10 parts of polyvinyl alcohol, 1-3 parts of glycol, 1-4 parts of dipropylene glycol mono butyl ether, 0.3-1 part of hydroxy propyl distarch phosphate, 0.3-1.5 parts of sodium gluconate, 0.3-1.5 parts of 2-furan-dimethyl silanol, 5-10 parts of an auxiliary agent and 20-35 parts of water. The waterproof antibacterial marine coating brought forward in the invention has advantages of high hardness, excellent waterproofness and antibacterial property, good comprehensive performance and long service life.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a waterproof and antibacterial marine coating. Background technique [0002] Marine coatings are a general term for coatings used in various parts of ships and marine engineering structures to meet the special requirements of preventing seawater, marine atmospheric corrosion, marine organisms, and other special requirements. Coatings used for ships are required to have good adhesion, good water resistance, chemical resistance and abrasion resistance; they can be used under harsh conditions such as the ocean, and have a long-term anti-rust life. It can be used for up to 10 or 15 years. However, the hardness of the existing marine coatings is not very ideal. During the sailing process of the ship, it is easy to be scratched and loses its performance. In addition, its water resistance and antibacterial properties are not good, which shortens the service life of the marine coatings...
