Abstract

The invention provides an antifouling paint and a method for preventing fouling on the surface of a substrate, wherein the antifouling paint comprises the following components in percentage by weight: 16-22% of water-based acrylic silicone resin; antifouling agent A20-28%; 20-30% of filler powder; 2-8% of pigment powder; 2-4% of thixotropic agent, and 2-34% of antifouling agent B20; 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, provided by the invention, the antifouling paint adopts the water-based acrylic silicon resin as a solvent and 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, and the problem that the antifouling paint in the prior art can discharge a large amount of volatile organic compounds to pollute the environment can be solved. In addition, when the antifouling paint is applied to the surface of a base material for antifouling, a coating with the thickness of 120 mu m is only needed to be sprayed to achieve a good antifouling effect, so that the VOC emission problem caused by an excessively thick antifouling coating is avoided.
