Embodiment Construction

[0009] 1. Preparation of gossypol antifouling agent

[0010] Take 100g of toluene and 20g of cottonseed cake and stir well to obtain a mixture, add 40g of cuprous oxide to the above mixture under high-speed stirring, evaporate toluene under reduced pressure, dry in a vacuum at 20-65°C, and grind to obtain the present invention gossypol antifouling agent.

[0011] When preparing the antifouling agent of the present invention, the weight ratio of the toluene to cuprous oxide is (10-100): (10-200). The cottonseed cake is cottonseed cake that has not been detoxified after extraction of cottonseed oil, and the content of gossypol is greater than 2%. It is vacuum-dried at 20-65°C, crushed, ground, and filtered through a 100-mesh filter And get.

[0012] 2. Preparation of Marine Antifouling Coatings

[0013] The marine antifouling paint is composed of resin solution, plasticizer, filler and gossypol antifouling agent of the present invention, and their weight percent ranges are re...

Abstract

A gossypol-type anti-fouling agent with excellent hipophilicity is perpared from toluene and cotton seed cake through mixing, high-speed stirring while adding cuprous oxide, vacuum distilling to remove toluene, drying and grinding. It can be used to prepare marine antifouling paint by proportionally mixing it with resin solution, plasticizer and filler.

Description

technical field [0001] The invention relates to an antifouling agent, in particular to a gossypol antifouling agent and a preparation method thereof, which can be used in antifouling coatings to prevent marine organisms from adhering to the surfaces of breeding nets, ships, coastal facilities and the like. Background technique [0002] The surface of nets, hulls, buoys, piers, piers and other devices in contact with seawater is often fouled due to the attachment of marine organisms, increasing surface friction resistance and accelerating corrosion. The best way to tackle marine biofouling is to apply paints that contain antifouling agents. At present, the copolymer of tributyltin methacrylate and methyl methacrylate and cuprous oxide (Cu 2 O) the composition is used as a kind of antifouling paint, is coated on surfaces such as the bottom of a ship, and can effectively prevent the harm of marine fouling organisms. The copolymer in this antifouling paint will be hydrolyzed i...
