Embodiment 1

[0028] Add 170.8g of propylene glycol methyl ether and 81.4g of zinc oxide into a four-necked flask equipped with a stirrer, condenser, and thermometer, raise the temperature to 75-80°C, add 86.1g of methyl methacrylate, 144.2g of isocyanate dropwise within 3 hours The mixture of caprylic acid and 10.0g deionized water was kept in a reflux state during the dropwise addition. After the dropwise addition, keep the temperature for 2 hours, then add 95.0 g of propylene glycol methyl ether to complete the reaction, and then obtain a transparent zinc acrylate monomer solution. The solid content of the above solution was measured to be 50%.

Embodiment 2

[0030] Add 15.0 g of propylene glycol methyl ether and 57.0 g of xylene mixed solvent into a four-necked flask equipped with a stirrer, condenser, thermometer, and nitrogen conduit. ℃, then weigh the mixture of 10.0g methyl methacrylate, 52.0g ethyl acrylate, 31.0g triisopropylsilyl acrylate, 14.0g zinc acrylate monomer and 1.5g azobisisobutyronitrile, stir completely After dissolving, drop it into the flask at a constant speed within 3 hours through a constant pressure dropping funnel, and then add a mixed solution of 0.5g benzoyl peroxide and 10g xylene dropwise within half an hour after the dropwise addition, and finish after 2.5 hours of heat preservation Reaction, that is, a colorless transparent acrylate zinc / silicon copolymer resin is obtained.

Abstract

The invention provides zinc acrylate and silicon copolymerized antifouling resin and a preparation method thereof. The resin comprises the following components in percentages by weight: 3-18% of a zinc acrylate monomer solution, 8-17% of acrylic silane ester, 25-30% of other acrylic acid ester polymerisable unsaturated monomers, 0.8-1% of an initiator, and 47-55% of a mixed solvent. The resin at least comprises three kinds of matrix resin components which are selected from zinc acrylate monomers, acrylic silane ester monomers, and other unsaturated monomers with radical-initiated polymerization, and the monomers are copolymerized in order to prepare anti-fouling paint for environmental vessels. The regulation of hydrolysis speed and cost of the coating is realized by adjusting proportion of hydrolyzed monomers, the preparation technology is simple, and compounds generated after hydrolysis of the coating do not generate adverse effects for ecological environment.

Description

technical field [0001] The invention relates to a marine antifouling paint, and also relates to a preparation method of the marine antifouling paint. Background technique [0002] The main and most economical way to prevent marine biofouling is to apply antifouling paint. In the past few decades, organotin self-polishing antifouling coatings, as a cross-age commodity, can effectively prevent marine organisms from attaching to fouling, but at the same time, their hydrolyzed products are stable and easy to accumulate in water bodies, which can cause oysters and other organisms deformed and enters the food chain. Therefore, the International Maritime Organization requires a complete ban on the use of organotin self-polishing antifouling coatings since 2008, and the development of new hydrolyzable antifouling resins has become the research focus of tin-free self-polishing antifouling coatings. [0003] For effective and efficient removal of fouling organisms from surfaces, it ...
