Environment-friendly antifouling paint and preparation method thereof

Abstract

The invention discloses an environment-friendly antifouling paint and a preparation method thereof, relates to the technical field of paints, and solves the problems that the existing tin-free self-polishing antifouling paint takes a copper antifouling agent as a main material, is added with an auxiliary toxic agent, and forms a low-release-rate antifouling paint together with heterocyclic compounds such as zinc and copper complexes, wherein the harm of massive accumulation of copper and auxiliary toxic agents to marine organisms is almost equal to that of organic tin and the like. According to the environment-friendly antifouling paint and the preparation method thereof, the environment-friendly antifouling paint is prepared from the following components in parts by weight: 60 parts of matrix resin, 20 parts of a solvent, 5 parts of an auxiliary solvent, 5 parts of a base material, 2 parts of a defoaming agent, 3 parts of a thickening regulator, 2 parts of an antifouling agent, 2 parts of a resin activator and 1 part of an active monomer, the matrix resin is prepared from the following components in parts by weight: 30 parts of pyromellitic dianhydride, 20 parts of phthalic acid and 10 parts of hydroxymethyl. The environment-friendly copper-free organic antifouling agent is formed by adopting the resin as a base material, and the antifouling agent is free of toxicity and can be continuously degraded.

Description

technical field [0001] The invention relates to the technical field of paint materials, in particular to an environment-friendly antifouling paint and a preparation method thereof. Background technique [0002] With the rapid development of social economy, developed economy and trade are increasingly dependent on advanced shipping and shipbuilding. In the ocean, the corrosion of the hull occurs all the time. In addition, marine organisms attach to the hull, which will increase the Weight, increase navigation resistance, reduce ship speed, increase fuel consumption, in order to reduce the harm of marine organisms and prevent marine organisms from fouling ships, coating scientists have studied a variety of antifouling technologies; the earliest humans used mercury, arsenic, etc. Compound configuration antifouling paint, but because these substances are highly toxic, they were eliminated; then developed an antifouling paint with cuprous oxide as the main antifouling agent, rosi...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a kind of environment-friendly antifouling paint and preparation method thereof, to solve the existing existing tin-free self-polishing antifouling paint that is proposed in the above-mentioned background technology is mainly based on copper antifouling agent, supplemented Toxic agent, which forms a low-release antifouling coating with heterocyclic compounds such as zinc and copper complexes, in which the large accumulation of copper and auxiliary toxic agents is almost equivalent to the harm to marine life as organic tin and other problems
