Problems solved by technology

[0003] As a mainstream antifouling agent, cuprous oxide has the disadvantages of large dosage and low efficiency in antifouling coatings. In many ship marine antifouling coatings, the dosage of cuprous oxide reaches more than 40-50wt%.
This leads to the sudden release of cuprous oxide in the early stage of antifouling coatings, which also has a lot of adverse effects on the marine environment, so it is imperative to control the amount of cuprous oxide in antifouling coatings

Abstract

The invention relates to an antifouling paint based on a urushiol benzoxazine copper polymer. The antifouling paint comprises the following raw materials in parts by weight: 95-105 parts of urushiol benzoxazine copper polymer, 0-30 parts of cuprous oxide, 3-10 parts of auxiliary antifoulant, 3-10 parts of antibacterial agent, 1-3 parts of auxiliary and 20-60 parts of solvent. The invention furtherrelates to a preparation method of the antifouling paint based on the urushiol benzoxazine copper polymer. The antifouling paint based on the urushiol benzoxazine copper polymer, provided by the invention, has the advantage that the usage amount of cuprous oxide is greatly reduced.

Description

technical field [0001] The invention relates to an antifouling paint, in particular to an antifouling paint based on urushiol benzoxazine copper polymer and a preparation method thereof. Background technique [0002] Marine fouling is a problem that people have been facing since the beginning of their activities in the ocean. In order to deal with this problem, people have invented a variety of antifouling technologies, among which the most effective and convenient method is to apply marine antifouling coatings. The development of marine antifouling coatings largely depends on the development of antifouling agents. As early as the 1950s, cuprous oxide became the main antifouling agent, and the organotin antifouling agent that appeared later quickly replaced the position of cuprous oxide because of its superior antifouling performance, but in the 1980s, The use of organotin has been gradually banned by countries all over the world due to serious pollution problems, and cupr...
