Abstract

The invention relates to preparation and application of zinc acrylate-type self-polishing matrix resin for an antifouling coating. The matrix resin has good self-polishing property, and the antifouling coating prepared by using the matrix resin has the characteristics of being long in anti-fouling period, excellent in anti-fouling property, excellent in polishing and drag-reduction performances and the like. The invention provides the anti-fouling coating prepared from the zinc acrylate-type self-polishing matrix resin for the antifouling coating. The matrix resin has good self-polishing property, and the anti-fouling coating prepared by the matrix resin has the characteristics of being long in antifouling period, excellent in antifouling property, excellent in polishing and drag-reduction performances and the like. The anti-fouling coating does not contain toxic substances such as tin and dichloro-diphenyl-tricgloroethane (DDT), has the characteristics of being friendly to the marine environment, simple and convenient to construct, easy to maintain and the like, and can meet the requirements of underwater facilities on the long-term antifouling coating in the sea.

Description

technical field [0001] The invention relates to the preparation and application of a zinc acrylate type self-polishing antifouling coating matrix resin. The matrix resin has good self-polishing performance, and the antifouling coating prepared with the matrix resin has long antifouling period and excellent antifouling performance , Polishing drag reduction performance and other characteristics. Background technique [0002] Marine biofouling will increase the weight of structures in the sea, block water flow channels, and even cause surface corrosion, which will significantly increase maintenance costs and cause huge economic losses. Since ancient times, humans have taken various means to prevent the adhesion of marine organisms. After continuous attempts, coating marine antifouling coatings containing antifouling agents has become the most effective, economical and feasible method to solve marine biofouling. [0003] However, with the increasing dependence of human beings ...
