Embodiment 1

[0025] Example 1: Weigh 30g of benzisothiazolinone and 22.8g of glutaric anhydride and put them in a 250ml three-necked flask. At this time, the molar ratio of benzisothiazolinone to glutaric anhydride is about 1:1. Add 200ml of mixed solvent of DMF and xylene, stir and disperse at low temperature for 10min, then raise the temperature of the three-necked flask to 60°C and stir for 1h to fully dissolve the reactants in the three-necked flask, then slowly raise the temperature to 120°C for the three-necked flask and react After 7 hours, a dark brown object was obtained, and the dark brown object was ground to a powder state by a grinder, and then the unreacted glutaric anhydride was removed with a small amount of deionized water to prepare the modified benzisothiazolinone derivative.

Embodiment 2

[0026] Example 2: Weigh 30g of benzisothiazolinone and 20g of maleic anhydride and put them in a 250ml three-necked flask. At this time, the molar ratio of benzisothiazolinone to maleic anhydride is about 1:1, add DMF single solvent 200ml and stir and disperse at low temperature for 12min, then raise the temperature of the three-necked flask to 70°C and stir for 0.9h to fully dissolve the reactants in the three-necked flask, then slowly raise the temperature of the three-necked flask to 110°C and react for 6h to obtain a dark brown color Object, the dark brown object is ground into a powder state by a grinder, and then the unreacted maleic anhydride is removed with a small amount of deionized water to prepare the modified benzisothiazolinone derivative.

Embodiment 3

[0027] Example 3: Weigh 30g of benzisothiazolinone and 20g of succinic anhydride and put them in a 250ml three-necked flask. At this time, the molar ratio of benzisothiazolinone to succinic anhydride is about 1:1, add The mixed solvent of xylene and DMF was 200ml and stirred and dispersed at low temperature for 14min, then the temperature of the three-necked flask was raised to 80°C and stirred for 0.7h to fully dissolve the reactants in the three-necked flask, and then the temperature of the three-necked flask was slowly raised to 100°C and reacted After 7 hours, a dark brown object was obtained, and the dark brown object was ground to a powder state by a grinder, and then the unreacted succinic anhydride was removed with a small amount of deionized water to prepare the modified benzisothiazolinone derivative.

Abstract

The invention discloses a method for preparation of zinc acrylate resin by grafting modified benzisothiazolinone, the method comprises preparation of a modified benzisothiazolinone derivative and preparation of zinc acrylate resin, in the preparation process of the modified benzisothiazolinone derivative, dicarboxylic anhydride, a solvent and deionized water, in the preparation process of the zinc acrylate resin, a zinc containing material and acrylic resin are used, by the method, the zinc acrylate resin containing the modified benzisothiazolinone can be obtained, the zinc acrylate resin containing the modified benzisothiazolinone has an anti-fouling structure similar to a tributyltin side chain, marine bacteria growth inhibition test shows that: the zinc acrylate resin not only has antibacterial function, but also can inhibit the adhesion and growth of marine organisms, has hydrolyzing polishing function, can delay the release of an antifouling agent, and can effectively prolong the antifouling service life of the coating.

Description

technical field [0001] The invention belongs to the technical field of material grafting, and in particular relates to a method for preparing zinc acrylate resin by grafting modified benzisothiazolinone. Background technique [0002] Most of the resins used in existing antifouling coatings are acrylic resins, chlorinated rubber, and chlorinated ethers. Such materials do not have antifouling effects by themselves, and the inhibition of marine biofouling can only be achieved by physically adding antifouling agents, such as adding oxidation The actual application effect of self-polishing antifouling coatings based on zinc acrylate, silicon, and copper resins is far lower than that of organotin self-polishing antifouling coatings. The main reason is that these materials do not have similar organic tin The antifouling structure of the resin side chain butyltin reduces the synergistic antifouling effect between the antifouling agent and the resin. [0003] In response to this pro...
