Description

technical field [0001] The invention belongs to the technical fields of luminescent paint, stain-resistant paint, antifouling paint and underwater paint, and in particular relates to a nano antibacterial low surface energy organosilicon luminescent antifouling paint and a preparation method thereof. Background technique [0002] The fouling problem of marine organisms has always restricted people's development and utilization of marine resources. The attachment of various marine organisms will increase the ship's navigation resistance and fuel consumption. The metabolites of marine organisms will corrode the ship and increase the ship's life. Maintenance costs will reduce the voyage rate of ships, and marine organisms will also block various pipelines, valves and meshes of culture cages on the seabed, causing economic losses that are difficult to estimate. In order to achieve the prevention and control of marine organisms, anti-fouling coatings are the only widely used and e...
