Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the existing ship antifouling coatings are toxic, affect the water environment, cause great harm to human health, quickly lose antifouling effect, complex production process, and high cost. Aiming at the above problems, the present invention The purpose is to provide a grafted resin with low surface energy, non-toxic and harmless, good stability, long-lasting antifouling effect, simple process and low cost, which has both hydrolysis characteristics and low surface energy characteristics, and the antifouling resin prepared by the resin Coatings, overcoming the deficiencies of the prior art

Abstract

A grafted resin and an anti-fouling paint produced by this resin, is to prepare monomers mixture with methyl methacrylate, ethyl acrylate, butyl acrylate, acrylic acid, hema, chain transfer agent and initiator. The monomers mixture and mixed solvent are used to prepare the acrylic containing hydroxyl. Then ethyl silicate, anhydrous ethanol, deionized water and dilute hydrochloric acid are used to prepare polysiloxane. The hydroxyl acrylic, polysiloxane, catalysts, and mixed solvents are prepared the grafted resins with hydrolysis and low surface energy. The grafted resins, anti-fouling paint, color filler, additives, and mixed solvent are prepared the anti-fouling paint.

Description

Technical field: [0001] The present invention relates to a kind of resin and the paint prepared with the resin, especially a kind of grafted resin with hydrolysis characteristic and low surface energy characteristic and the antifouling paint prepared with the resin, which is mainly used for ship antifouling, and can also be used to others. Background technique: [0002] A variety of marine organisms will adhere to the parts below the waterline of ships navigating in the ocean, and coating antifouling coatings on ships is the most effective way to prevent marine organisms from adhering. Traditional antifouling coatings use copper, arsenic, mercury, lead, tin and other toxic materials released from the coating to kill marine organisms. Organotin self-polishing antifouling coatings have good antifouling effect and long antifouling period It was widely used at one time, but the release of harmful substances caused serious harm to the ecological environment and human health.
