Abstract

The invention relates to an environment-friendly low-surface-energy antifouling paint used under a waterline. The paint is prepared from the following raw materials by mass: 10-16% of a base material; 9%-13% of a filler; 8%-12% of pigment; 5-9% of a curing agent; 7%-9% of organic tin; 6%-8% of polysiloxane; 8%-12% of polyurethane; 9%-11% of epoxy modified organic silicon rubber; and 8-10% of an additive. The base material is a mixture of polydimethylsiloxane and epoxy resin. The filler is a mixture of polytetrafluoroethylene and paraffin oil. The pigment is a mixture of titanium dioxide and magnesium oxide. The curing agent is polyamide. The additive is a mixture of polytetrafluoroethylene, a graphite intercalation compound and fluorinated carbonate. The invention has the technical effects of environmental protection, low surface energy and better antifouling effect.

Description

technical field [0001] The invention relates to the technical field of antifouling paints, in particular to an environment-friendly low surface energy antifouling paint used under the waterline. Background technique [0002] Surfaces submerged in seawater are susceptible to contamination by marine organisms such as green and brown algae, barnacles, mussels, tube worms, and the like. For marine structures such as ships, oil platforms, buoys, etc., such pollution is undesirable and has economic consequences. This contamination can lead to biodegradation of its surface, increased loading and accelerated corrosion. Contamination of the vessel will increase frictional drag, which will result in reduced speed and / or increased fuel consumption. This may also lead to a decrease in handling performance. Antifouling coatings are used to prevent the settling and growth of marine life. These coatings typically contain film-forming binders, along with various components such as pigme...
