Embodiment 1

[0016] The specific process of the preparation method of the microstructure surface antifouling material involved in this embodiment is as follows: sequentially add 75 parts by mass of hydroxyl-terminated polydimethylsiloxane and 10 parts by mass of acrylonitrile with a mass percentage of 10% to a stirred tank. Nitrile grafted silicone resin and 10 parts by mass of dibutyltin dilaurate and silicon 40 are mixed to form a compound. After stirring evenly, add 3 parts by mass of ethylenediamine to form a mixture, add 1 part by mass of xylene, stir evenly, pass After degassing and removing bubbles under reduced pressure, it is coated on the surface of the substrate to form a coating. After the coating is cured, the water-soluble organic amine is washed and dissolved to remove water and absorb water to form micro droplets to prepare a micron-scale microstructure surface antifouling material.

Embodiment 2

[0019] The specific process of the preparation method of the microstructure surface antifouling material involved in this embodiment is: sequentially adding 45 parts by mass of hydroxyl-terminated polydimethylsiloxane and 45 parts by mass of acrylonitrile with 1% acrylonitrile by mass into the stirred tank. Nitrile grafted silicone resin and 6 parts by mass of stannous octoate and methyltriethoxysilane are mixed to form a compound. After stirring evenly, add 1 part by mass of triethylenediamine to form a mixture, add 10 parts by mass of xylene, Stir uniformly, remove bubbles by degassing under reduced pressure, and apply to the surface of the substrate to form a coating. After the coating is cured, the water-soluble organic amine is washed and dissolved to remove water-soluble organic amines and absorb water to form micro-droplets to prepare micron-scale microstructure surface antifouling material.

Embodiment 3

[0021] The specific process of the preparation method of the microstructure surface antifouling material involved in this embodiment is: sequentially adding 60 parts by mass of hydroxyl-terminated polydimethylsiloxane and 30 parts by mass of acrylonitrile with a mass percentage of 2% to a stirred tank. Nitrile grafted silicone resin and 8 mass parts of dibutyl diacetyl tin and silicon 40 are mixed to form a compound. After stirring evenly, add 2 mass parts of diethylene triamine to form a mixture, add 5 mass parts of xylene, and stir Uniformity, after the bubbles are eliminated by degassing, the coating is applied to the surface of the substrate to form a coating. After the coating is cured, the water-soluble organic amine is washed and dissolved to remove water-soluble organic amines and form micro-droplets to prepare micron-scale micro-structured surface antifouling materials .

Abstract

The invention belongs to the technical field of marine organism fouling protection. The invention relates to a microstructure surface antifouling material and a preparation method thereof. Hydroxyl-terminated polydimethylsiloxane, a curing agent, acrylonitrile grafted organic silicon resin and water-soluble organic amine are used as main raw materials, wherein the hydroxyl-terminated polydimethylsiloxane is a main body material for preparing a surface microstructure; water-soluble organic amine is used as corrosion particles, acrylonitrile grafted organic silicon resin is used as a corrosion particle coating agent, a surface microstructure is constructed through the self-assembly effect of the acrylonitrile grafted organic silicon resin and the water-soluble organic amine, and the antifouling purpose is achieved through the characteristics that the surface of the microstructure contaminates biological larvae, the effective attachment area of spores is small, and attachment is not firm.Compared with the prior art, no antifouling agent such as cuprous oxide, cuprous thiocyanate and organic tin is used, no destructive influence is caused to the marine ecological environment, and themarine antifouling agent can be widely applied to surface marine organism fouling protection of marine engineering facilities and structures such as docks, drilling platforms, piers and piles and hasgood potential economic benefits.

Description

Technical field: [0001] The invention belongs to the technical field of marine biological fouling protection, and specifically relates to a microstructure surface antifouling material and a preparation method thereof. The fouling organism larvae or spores have the characteristics of small effective attachment area and weak attachment on the microstructure surface, and are based on dissolution. The control of particles prepares antifouling materials with surface microstructures. Background technique: [0002] Marine fouling organisms are the general term for microorganisms, plants and animals that grow on the bottom of ships and on the surface of all facilities in the sea. Marine fouling seriously affects the speed of ships, increases fuel consumption, and at the same time damages ship accessories and structures, and seriously affects navigation economy It is necessary to take measures to prevent and control sex and safety. Marine antifouling coatings have experienced a developme...
