Embodiment 1

[0054] Embodiment 1 (resin R-1)

[0055] Dissolve 16 parts of zinc acrylate (ZDAA) in 16 parts of propylene glycol methyl ether acetate in a mixing container, then add 8 parts of acrylamide, 68 parts of ethyl acrylate, 8 parts of methyl methacrylate, 5 parts of xylene, 5 parts of butyl acetate and 8 parts of azobisisoheptanonitrile were stirred evenly to form a mixed monomer solution. Add 60 parts of xylene and 20 parts of propylene glycol methyl ether acetate into a reaction vessel equipped with a stirring device, a condenser, a dropping device and a thermometer, and heat to 100°C. Maintaining the reaction temperature at 100° C., the mixed monomer solution was added dropwise into the reaction vessel at a constant speed within 6 hours, and then the reaction temperature was maintained for 1 hour. Dissolve 0.5 parts of azobisisovaleronitrile in 8 parts of xylene, drop it into the reaction vessel at a constant speed within 0.5 hours, and keep the reaction temperature for 2 hours...

[0056] Embodiment 2 (resin R-2)

[0057] Dissolve 28 parts of zinc acrylate (ZDAA) in 28 parts of propylene glycol methyl ether acetate in a mixing vessel, then add 10 parts of acrylamide, 46 parts of n-butyl acrylate, 16 parts of methyl methacrylate, 4 parts of xylene , 4 parts of butyl acetate and 9 parts of azobisisoheptanonitrile were stirred evenly to form a mixed monomer solution. Add 50 parts of xylene and 20 parts of propylene glycol methyl ether acetate into a reaction vessel equipped with a stirring device, a condenser, a dropping device and a thermometer, and heat to 90°C. Maintaining the reaction temperature at 90°C, the mixed monomer solution was added dropwise to the reaction vessel at a constant speed within 6 hours, and then the reaction temperature was maintained for 1 hour. Dissolve 0.5 parts of tert-butyl peroxy-2-ethylhexanoate in 6 parts of xylene, drop it into the reaction vessel at a constant speed within 0.5 hours, and keep the reaction temperature for...

Abstract

The invention relates to polyurea-modified organic zinc salt-containing acrylic resin as well as a preparation method and application thereof. Acrylamide and organic zinc salt are introduced into an acrylate resin structure at the same time, and then isocyanate reacts with acylamino in the acrylate resin structure to form the polyurea-modified organic zinc salt-containing acrylic resin. With the resin used as a film forming matter, an environment-friendly antifouling agent, a pigment filler, an auxiliary agent, a solvent and the like are added, and therefore, environment-friendly antifouling paint can be obtained. The antifouling paint has excellent physical and mechanical properties; the antifouling property of the antifouling paint is excellent, and the antifouling period of the antifouling paint is long; the paint does not contain organic tin, dichlorodiphenyl trichloroethane and other antifouling agents, an antifouling agent compounding system meeting the requirements of environmental protection laws and regulations is used, so that marine environment friendliness is achieved; good fresh water soaking resistance is achieved, and the use requirement that a ship enters a fresh water river can be met; the single-component paint is low in VOC content, simple and convenient to construct and easy to maintain; and expensive acrylate monomers are not used, so that the paint has very high cost performance and is beneficial to popularization and application.

Description

technical field [0001] The invention relates to the technical field of antifouling coatings, in particular to a polyurea-modified acrylic resin containing organic zinc salts and a preparation method and application thereof. Background technique [0002] Marine fouling organisms mainly refer to the general term of animals, plants and microorganisms attached to the bottom of ships, buoys and all artificial facilities, and are one of the important factors affecting the safety and service life of marine facilities. For ships navigating in the ocean, marine fouling organisms attach to the bottom surface of the ship, which will significantly increase navigation resistance, increase fuel consumption, and aggravate the global greenhouse effect; for static marine engineering facilities serving in the ocean , the uneven attachment of marine fouling organisms will cause its center of gravity to shift, affecting its operational stability; for sensing instruments such as sonar in the sea...
