Problems solved by technology

However, since fluorine-containing resin is basically the material with the lowest surface energy that can be found at present, it requires extremely clean conditions during preparation, and the requirements for the process are extremely strict, so there are certain difficulties in practical use.

Embodiment 1

[0025] First, put 40mmol of the alkaloid 3-dimethylaminomethylindole into the reaction vessel, then add 20mmol of potassium hydroxide, and slowly drop in 60mmol of 3-chloropropene under stirring condition to form N,N-dimethyl Formamide is used as a solvent. After the reaction is completed, the reaction mixture is added to water, and then extracted with chloroform. After the extract is dried, the chloroform is removed by vacuum filtration, and the N-allyl 3- Alkaloid derivatives of the dimethylaminomethylindole structure.

[0026] Then, add 3.0 mmol of hydrogen-containing silicone oil, 10.0 mmol of alkaloid derivatives, and 6.0 ml of anhydrous toluene into a reaction vessel equipped with a stirring magnet, and mix well.

[0027] The third step is to add a small amount of dichlorodicyclopentadiene platinum as a catalyst. Under the protection of argon, the temperature is controlled at 50 ° C, stirred, and reacted for 24 hours. After cooling, the solvent is evaporated under reduce...

Abstract

The invention relates to a biological antifoulant which can restrain the growth of sea organisms as mussel and barnacle on the face of ship, while it has low surface energy character. The inventive production comprises that extracting biological alkali from bulrush or barley to prepare N-pi-allyl derivant, to be chemically combined with hydrogen silicon oil. The invention is innocuous, with low surface energy character, better antifouling function, and wide application.

Description

Technical field: [0001] The invention relates to a biological antifouling agent and a preparation method thereof. Specifically, it is a biological antifouling agent with low surface energy characteristics for preventing and removing marine organisms attached to the surface of ships and marine structures in the marine environment, and belongs to the field of marine fouling protection. Background technique: [0002] There are a large number of marine organisms in seawater, and these marine organisms will adhere to the surface of ships and structures that have been in the seawater environment for a long time. This adhesion will increase the traveling resistance of the ship, seriously affect the sailing speed of the ship, increase fuel consumption, and at the same time damage the anti-corrosion coating on the surface of the ship and structures, thereby causing corrosion and damage on the surface of the hull and structures, seriously affecting its security. Therefore, it is of ...
