Abstract

The invention discloses a formula and preparation method of low-surface-energy long-acting anti-fouling paint. The formula contains the ingredients in percentage by mass: 18.0% to 22.0% of polysiloxane resin polymer, 12% to 18% of polytrifluorochloroethylene resin polymer, 26.0% to 32.0% of organic solvent, 18% to 32% of pigment/filler, 3% to 5% of dispersant, 0.8% to 2.6% of thickener, 0.1% to 0.2% of antifoamer and 0.1% to 0.2% of leveling agent. The prepared paint is used for protecting ocean shipping ships and can achieve a long-acting anti-fouling effect.

Description

technical field [0001] The invention relates to an antifouling paint for protection of oceangoing ships, in particular to a formulation of a long-lasting low surface energy antifouling paint and a preparation method thereof. Background technique [0002] Marine growth will not only reduce the speed of the ship and increase the fuel consumption, but also increase the corrosion damage of the ship and underwater facilities, and significantly shorten the service life. Brushing antifouling paint on the surface of these structures is an important way to solve the above problems. Traditional antifouling coatings use poisonous materials such as copper, tin, mercury, and lead released from coatings to kill marine organisms. Although this can reduce or eliminate marine fouling, the release of harmful substances will affect the ecological environment and Human health has also caused serious harm. This problem has been highly valued by countries all over the world. Many countries have ...
