[0031] a. Preparation of zinc acrylate small molecule monomer (a1)

[0032] Add a stoichiometric amount of solvent and zinc oxide or zinc hydroxide into a four-necked flask equipped with a stirring device, condenser, dropping funnel, and thermometer. The temperature is increased to 70~90℃, and one saturated organic acid and the other Unsaturated organic carboxylic acid and a certain amount of deionized water are mixed uniformly according to the metering ratio, and added dropwise to a four-neck bottle, dripping for 2 to 3 hours, and then keep warm until the mixture is clear and transparent, cool down and discharge, add solvent , Controlling the solid content of the zinc acrylate small molecule monomer at 30-55% to obtain the zinc acrylate small molecule monomer (a1) of the present invention.

[0033] In the process of preparing zinc acrylate small molecule monomer (a1), the molar ratio of zinc oxide or zinc hydroxide to a saturated organic acid and another unsaturated organic carbox...

[0046] a. Zinc acrylate small molecule monomer a1-1

[0047] In a four-necked flask equipped with a stirring device, a condenser, a dropping funnel, and a thermometer, add 200 parts of propylene glycol methyl ether and 81.4 parts of zinc oxide under stirring, and heat to 80°C. A mixture of 86.1 parts of methacrylic acid, 74.1 parts of propionic acid, and 20 parts of water was dropped from the dropping funnel for 3 hours. Keep warm until the mixture is clear and transparent. The temperature was lowered and 40 parts of propylene glycol methyl ether were added to prepare the zinc acrylate small molecule monomer a1-1. The measured solid content of a1-1 is 44.6%.

Abstract

The invention relates to preparation and application of zinc acrylate-type self-polishing matrix resin for an antifouling coating. The matrix resin has good self-polishing property, and the antifouling coating prepared by using the matrix resin has the characteristics of being long in anti-fouling period, excellent in anti-fouling property, excellent in polishing and drag-reduction performances and the like. The invention provides the anti-fouling coating prepared from the zinc acrylate-type self-polishing matrix resin for the antifouling coating. The matrix resin has good self-polishing property, and the anti-fouling coating prepared by the matrix resin has the characteristics of being long in antifouling period, excellent in antifouling property, excellent in polishing and drag-reduction performances and the like. The anti-fouling coating does not contain toxic substances such as tin and dichloro-diphenyl-tricgloroethane (DDT), has the characteristics of being friendly to the marine environment, simple and convenient to construct, easy to maintain and the like, and can meet the requirements of underwater facilities on the long-term antifouling coating in the sea.

Description

Technical field [0001] The invention relates to the preparation and application of an acrylic zinc-type self-polishing antifouling coating matrix resin. The matrix resin has good self-polishing performance, and the antifouling coating prepared by using the matrix resin has long antifouling period and excellent antifouling performance. , Excellent performance of polishing and drag reduction. Background technique [0002] Marine biological fouling can increase the weight of structures in the sea, block water flow channels, and even cause surface corrosion, which significantly increases maintenance costs and brings huge economic losses. Since ancient times, humans have adopted various methods to prevent the adhesion of marine organisms. After continuous attempts, coating marine antifouling paints containing antifouling agents has become the most effective, economical and feasible method to solve marine organisms fouling. [0003] However, as human beings rely more and more on the oce...
