Abstract

The invention belongs to the technical field of coatings, and particularly relates to a coating composition containing an acrylic acid body hybrid emulsion. The coating composition is prepared from styrene, azobisisobutyronitrile, acrylic acid butyric acid, a modifier, methyl methacrylate, methacrylic acid, fluorine-containing ternary copolymer resin, hydroxyethyl methacrylate, titanium dioxide, an ultraviolet light absorber 5060, butyl acetate, xylene, iron oxide red, aluminum tripolyphosphate, modified zinc phosphate, an antifoaming agent, a dispersant and 1250 mica powder. The coating composition has the advantages that by means of the coating, marine organisms can be effectively prevented from adhering to the bottom of a ship, the variation cannot be caused to the marine organisms, andthe damage cannot be caused to the marine environment.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to a coating composition containing an acrylic bulk hybrid emulsion. Background technique [0002] Marine biofouling is becoming more and more serious. However, marine biofouling has not yet been resolved. The fouling of attached organisms mainly refers to the attachment of organisms, mainly algae and shellfish, to the surface of marine facilities, affecting the normal operation of equipment. Taking ships as an example, marine organisms attach to the bottom of the ship, causing huge resistance when the ship is running, reducing the speed of the ship, and consuming a lot of energy at the same time. The study found that for the 10,000-ton ship, the fouling of the ship's bottom reached about 5%, and the fuel consumption increased by about 10%, which caused huge economic losses due to the adhesion of marine organisms to the bottom of the ship. [0003] In order to prevent the attach...
