Embodiment 1

[0019] Example 1 Preparation of water-based soft biomass flexible cross-linked antifouling coating

[0020] (1) Synthesis of water-based acrylic resin

[0021] In a four-necked flask equipped with a stirrer, reflux condenser, and constant pressure dropping funnel, 0.2g of benzoyl peroxide and 200g of ethanol were added, and the temperature was raised to 78°C. Then, 12g of acrylic acid and 46g of methyl were added to the mixture. A mixture of methyl acrylate, 71g ethyl acrylate, 63g butyl acrylate, 8g hydroxyethyl acrylate, 1.6g benzoyl peroxide, use a constant pressure dropping funnel to drip at a constant speed over 3 hours, add 0.2g Oxidize benzoyl, continue constant temperature reaction (78° C., the same below) for 3 hours, then cool to room temperature, add 25 g of ammonia water to adjust the pH to neutral, stir for 2 hours and complete the reaction to obtain an aqueous acrylic resin.

Abstract

The invention belongs to the technical field of marine protection and especially relates to an aqueous soft biomass anti-fouling paint and its preparation method. The aqueous soft biomass anti-fouling paint comprises dual components A and B, and mass ratio of the component A to the component B is 8-10: 1. The component A is a resin base-material carrier, and comprises the following ingredients, by weight, 60-66% of aqueous acrylic resin, 0-6% of iron oxide red, 5% of zinc oxide, 0-3% of active silica, 0-1% of organobentonite, 3-4% of zinc pyrithione, 3-4% of copper pyrithione, 9-10% of an antifouling agent, 5% of ethanol and 6% of water. The component B is a cross-linking agent. The formula adopted in the invention is nontoxic and harmless, and the anti-fouling paint obtained after mixing has a good antifouling effect.

Description

Technical field [0001] The invention belongs to the technical field of marine protection, and particularly relates to a water-based soft biological antifouling paint and a preparation method thereof. Background technique [0002] As we all know, the most effective and economical way to deal with marine biological fouling is to use anti-fouling coatings. Antifouling coatings have gone through several generations so far, and a complete set of coating resin preparation technologies represented by self-polishing type and low surface energy type have been formed, which has greatly promoted the development of marine coatings. Although the existing various antifouling coatings have better antifouling performance, they are mostly toxic and harmful, and have high VOC emissions, which are not conducive to environmental protection. Summary of the invention [0003] The present invention provides a water-based soft bio-based antifouling paint that not only meets the requirements of environme...
