The alpha-cypermethrin anti-fouling preparation is one kind of efficient environment friendly marine use anti-fouling preparation prepared with artificially synthesized derivative of pyrethrin as the pyrethrum extract and has low cost, high efficiency and environment friendship. Alpha-cypermethrin has the molecular expression of C22H19Cl2NO3, molecular weight of 416.35 and molecular structure as shown.
Description
technical field [0001] The invention relates to an antifouling agent, in particular to an artificially synthesized derivative of a plant pyrethrum flower extract (pyrethrin) as an efficient and environment-friendly marine antifouling agent. Background technique [0002] When the spores or larvae of marine fouling organisms such as algae, sponges, hydra, exogenous animals, snails, bivalves, barnacles, and sea squirts develop to a certain stage, they will attach to the surface of the object and metamorphose into adults . Because they are attached to the surface of ships, floating docks, offshore oil platforms, submarine cables, buoys and mines, cooling pipes of coastal power plants and seawater farming cages, etc., they increase ship resistance, block pipes and nets, accelerate metal corrosion, Increase the weight of offshore facilities, etc., causing huge losses in military activities, marine transportation, industry and aquaculture production. The worldwide cost of biofoul...
