Embodiment Construction

[0013] In order to illustrate the content of the present invention more clearly, specific embodiments are used to illustrate the following, and the specific embodiments do not limit the scope of the content of the present invention.

[0014] A method for preparing modified acrylic resin is prepared by the following steps:

[0015] (1) After adding 1.0kg acrylic monomer, 0.1kg azobisisobutyronitrile, and 16.0kg propylene glycol methyl ether solvent into the polymerization kettle, raise the temperature;

[0016] (2) After the temperature in the polymerization vessel reaches 100°C constant, start to titrate 16.0kg of acrylate monomer, 2.0kg of azobisisobutyl cyanide, 3.0kg of propylene glycol methyl ether solvent, and 13kg of zinc acrylate at the same time. The titration time is 6 Hour, the titration rate is 0.14L / min;

[0017] (3) After the titration, 2.0 kg of xylene (cleaning solvent) is sprayed into the titration kettle, and then dropped into the polymerization kettle (the purpose of...

Abstract

The invention discloses a modified acrylic resin preparation method and long-acting anti-fouling paint prepared from the modified acrylic resin. By adding of sodium polyacrylate into resin for the anti-fouling paint, sodium polyacrylate in resin absorbs water to swell when the anti-fouling paint contacts with water, and a protective film similar to a slime layer is generated on the resin surface and is elastic and capable of effectively preventing attachment of marine organisms and automatically polishing and updating along with continuous hydrolysis of acrylic resin. In addition, sodium polyacrylate is nontoxic intrinsically, is an environmental-friendly additive without release of toxic agents and belongs to non-contact environment-friendly anti-fouling painting, and high efficiency andenvironmental friendliness are realized.

Description

Technical field [0001] The invention relates to the technical field of antifouling coatings, and in particular to a method for preparing modified acrylic resin and a long-term antifouling paint prepared by using modified acrylic resin. Background technique [0002] The existing conventional antifouling paints for ships can only rely on contact poisoning effects or toxic repelling effects to prevent fouling. Antifouling paints with poisoning or toxic repelling effects tend to cause pollution to the ocean. Conducive to environmental protection. Summary of the invention [0003] In order to overcome the defects of the above methods, the present invention provides a method for preparing modified acrylic resin and a long-lasting antifouling paint prepared by using modified acrylic resin. [0004] The technical solution adopted by the present invention is: a method for preparing modified acrylic resin, which is prepared by the following steps: [0005] (1) After adding 1.0kg acrylic monom...
