Abstract

The invention provides a preparation method of a fluorine-containing self-polishing resin-based super-slip coating material. 1: Put fluorine-containing acrylate monomer, carboxyl-containing acrylic acid monomer, methyl methacrylate and ethyl acrylate in a weight ratio of 5-45:10-55:5-15:10-30 in total at 80°C Reaction at low temperature for 6 hours to synthesize a resin matrix; 2: react the obtained resin matrix with pyridine triphenylborane at a weight ratio of 70-90:5-30 in the total amount at 90° C. for 4 hours. Due to the self-polishing effect of the resin matrix, the distance from the lubricating oil to the coating surface will not increase, which can ensure a constant rate of lubricating oil exudation; when the lubricating oil in the coating is exhausted, the coating resin matrix can still Prevents fouling organisms from adhering to substrates through self-polishing action. The coating prepared by the invention solves the problem of easy loss of lubricating oil and causes coating failure, and is an environmentally friendly and long-lasting antifouling coating.

Description

technical field [0001] The invention relates to a method for preparing an antifouling coating, in particular to a method for preparing a self-polishing resin-based super-slip coating. Background technique [0002] The existence of marine fouling has brought great inconvenience to people in the development of marine resources and military activities at sea. Due to its unique oil layer protection effect, the ultra-slip coating can effectively prevent the adhesion of fouling organisms on the coating surface, reducing the harm caused by fouling organisms. [0003] However, the coating failure caused by the easy loss of lubricating oil is a common problem in super slippery coatings. Water erosion, external force damage, high temperature, and ultraviolet radiation will all lead to rapid loss of lubricating fluid. Once the lubricating fluid is lost, the pore structure on the surface of the super-slip coating will provide attachment points for fouling organisms, thereby acceleratin...
