Embodiment 1

[0036] The antifouling paint in the present embodiment comprises by weight percentage:

[0037]

[0038] Among them, the water-based acrylic silicone resin is selected from the production of NITTO KASEI DO., LTD in Japan. The antifouling agent A is selected from maleimide produced by Hubei Yunmei Technology, and the antifouling agent B is selected from copper pyrithione produced by Zhejiang Lijing Chemical Co., Ltd. The filler powder is selected from Guangxi Pingdu Shijie's talcum powder, the pigment powder is selected from Shanghai Yipin's iron oxide red, and the thixotropic agent is selected from Zhejiang Fenghong's bentonite.

Embodiment 2

[0040] Each component that the antifouling coating of present embodiment 2 is selected is identical with embodiment 1, and difference only is that the proportioning between each raw material component is different, and the antifouling coating of present embodiment 2 comprises by weight percentage:

[0041]

Embodiment 3

[0043] Each component that the antifouling coating of present embodiment 3 is selected is also identical with embodiment 1, and difference only is that the proportioning between each raw material component is different, and the antifouling coating of present embodiment 3 comprises by weight percentage:

Abstract

The invention provides an antifouling paint and a method for preventing fouling on the surface of a substrate. The antifouling paint comprises the following components in percentage by weight: 16-22% of water-based acrylic silicon resin; 20-28% of an antifouling agent A; 20-30% of filler powder; 2-8% of pigment powder; 2-4% of a thixotropic agent; 20-34% of an antifouling agent B; wherein the antifouling agent A comprises maleimide, and the antifouling agent B comprises copper pyrithione. According to the antifouling paint and the method for preventing fouling on the surface of the base material, the waterborne acrylic silicon resin is adopted as a solvent of the antifouling paint, and the antifouling paint basically does not contain volatile organic compounds, so that the antifouling paint basically does not discharge the volatile organic compounds after being sprayed on the surface of the base material; the problem that in the prior art, antifouling paint can discharge a large number of volatile organic compounds to pollute the environment can be solved. Besides, when the antifouling paint is applied to antifouling of the surface of a base material, a very good antifouling effect can be achieved only by spraying a 120-micron coating, and the problem of VOC emission caused by an over-thick antifouling coating is avoided.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to an antifouling coating and a method for antifouling on the surface of a substrate. Background technique [0002] Maritime transportation and the development of marine resources will use a large number of transport ships and various special marine ships, and the attachment of marine organisms (including marine microorganisms and algae) will increase the resistance of the ship's navigation, which will not only increase fuel consumption, but also Affecting the speed of navigation, causing direct or indirect losses to transport ships and marine special ships, this is a serious problem faced by the shipping and ocean development industries. At present, the most effective way to solve the problem of marine biological adsorption is to coat the outer layer of the hull with anti-fouling and anti-adhesion coatings for marine organisms. [0003] Existing antifouling paints genera...
