Embodiment Construction

[0006] 1, the preparation of basic zinc benzoate

[0007] Weigh 5.7 g of zinc chloride, 1.7 g of sodium hydroxide, and 6.1 g (0.042 mol) of sodium benzoate at a molar ratio of 1:1:1, respectively. Dissolve the weighed sodium benzoate and sodium hydroxide successively in 400ml of deionized water, slowly drop the solution of 5.7g of zinc chloride and 200ml of deionized water into it under high-speed stirring, and generate white turbidity, pH The value is about 7, and after being washed with deionized water several times, it is suction-filtered and dried to obtain basic zinc benzoate.

[0008] 2. Preparation of carboxyl-containing acrylic resin

[0009] Add 600ml of a mixed solution of toluene and n-butanol with a weight ratio of 4:1 into a four-necked round-bottomed flask equipped with a stirring device, a condenser, and a thermometer, raise the temperature to 80°C, and then drop the mixed solution within 3 hours. In the monomer mixture of 60g acrylic acid, 80g methyl methacry...

Abstract

A process for preparing acrylic resin containing zinc or copper characterized in that zinc or copper basic salt of organic acid is first synthesized, and acrylic resin containing carboxyl is then synthesized, thus obtaining the acrylic resin containing zinc or copper through the reaction between the zinc or copper basic salt of organic acid with the acrylic resin containing carboxyl. The acrylic resin containing zinc or copper can act as film forming article to be used in self-polishing anti-fouling paint containing no organotin, so as to prevent the adhesion of sea creatures on vessels and coastal facilities.

Description

technical field [0001] The invention relates to a preparation method of an acrylic resin containing zinc or copper, which can be used as a film-former of a self-polishing antifouling paint without organic tin. Background technique [0002] When fishing nets, boat bottoms, underwater facilities, etc. are exposed to seawater for a long time, the appearance and function are easily damaged by the adhesion, growth and reproduction of various marine fouling organisms on their surfaces. These marine fouling organisms include barnacles, hydra, Animals such as sea squirts, algae such as diatoms and green algae, and fungi such as bacteria and fungi. When they adhere to the bottom surface of the ship to grow and reproduce, on the one hand, it will increase the weight of the ship; on the other hand, it will increase the roughness of the bottom surface. The effects of these two aspects will lead to: ① Seriously affect the speed of the ship, so that the ship consumes more fuel; ② Damage ...
