Abstract

The invention discloses a resin for antifouling paint and a preparation method thereof. The resin is composed of the following components in parts by mass: 15-30 parts of MMA (methyl methacrylate), 10-20 parts of BA (butyl acrylate), 3-5 parts of st (styrene), 1-3 parts of AA (acrylic acid), 1-3 parts of A-171 silane coupling agent, 1-8 parts of perfluoroalkyl ethyl methacrylate, 0.3-0.8 part of initiator and 40-60 parts of solvent. The preparation method comprises the following steps: mixing dimethylbenzene, n-butyl acetate and n-butanol to obtain mixed solvent; uniformly mixing the A-171 silane coupling agent and the mixed solvent, and adding; uniformly mixing the MMA, BA, st, AA and initiator and the mixed solvent, and dropwisely adding; then uniformly mixing the perfluoroalkyl ethyl methacrylate and initiator and the mixed solvent, and dropwisely adding; uniformly mixing the initiator and the mixed solvent, and dropwisely adding; and finally cooling, and discharging. According to the invention, the advantages of simple process, low cost and the like are achieved; and the obtained resin has the advantages of excellent antifouling performance, no toxic substance, favorable overcoatability and the like.

Description

technical field [0001] The invention relates to a resin for antifouling paint and a preparation method thereof, in particular to a resin for antifouling paint and a preparation method thereof, which does not contain organic tin (TBT) and DDT poisonous materials, and has good matching properties of organic fluorine, Silicone modified acrylic resin. Background technique [0002] A large number of marine organisms attached to the surface of the ship will not only increase fuel consumption and transportation costs, but also accelerate the corrosion rate of the hull and shorten the service life of the ship. As a special coating, antifouling coating is mainly used to prevent the adhesion of marine organisms on the bottom of the ship. Low surface energy antifouling coatings are favored because they do not contain toxic antifouling agents (such as organotin, cuprous oxide, etc.) and have no pollution to the environment. At present, resins for low surface energy antifouling coating...
