Embodiment 1

[0016] The specific process of the preparation method of the microstructured surface antifouling material involved in this example is: sequentially add 75 parts by mass of hydroxyl-terminated polydimethylsiloxane, 10 parts by mass of acrylonitrile with a mass percentage of 10% propylene A compound formed by mixing nitrile grafted silicone resin and 10 parts by mass of dibutyltin dilaurate and silicon 40, after stirring evenly, 3 parts by mass of ethylenediamine is added to form a mixture, and 1 part by mass of xylene is added, stirred evenly, passed After degassing under reduced pressure to eliminate air bubbles, it is coated on the surface of the substrate to form a coating. After the coating is cured, the water-soluble organic amine is removed by water washing and erosion to absorb water to form micro-droplets, and a micron-scale microstructure surface antifouling material is prepared.

Embodiment 2

[0019] The specific process of the preparation method of the microstructured surface antifouling material involved in this example is: sequentially add 45 parts by mass of hydroxyl-terminated polydimethylsiloxane, 45 parts by mass of acrylonitrile with a mass percentage of 1% propylene A compound formed by mixing nitrile grafted silicone resin and 6 mass parts of stannous octoate and methyltriethoxysilane, after stirring evenly, 1 mass part of triethylenediamine is added to form a mixture, and 10 mass parts of xylene are added, Stir evenly, remove air bubbles through decompression and degassing, and then coat on the surface of the substrate to form a coating. After the coating is cured, remove water-soluble organic amines by washing and eroding to absorb water to form micro-droplets, and prepare micron-scale antifouling on the surface of the microstructure Material.

Embodiment 3

[0021] The specific process of the preparation method of the microstructured surface antifouling material involved in this example is: sequentially add 60 parts by mass of hydroxyl-terminated polydimethylsiloxane, 30 parts by mass of acrylonitrile with a mass percentage of 2% propylene A compound formed by mixing nitrile grafted silicone resin and 8 parts by mass of dibutyltin diacetyltin and silicon 40, after stirring evenly, add 2 parts by mass of diethylenetriamine to form a mixture, add 5 parts by mass of xylene, stir Uniform, after degassing under reduced pressure to eliminate air bubbles, it is coated on the surface of the substrate to form a coating. After the coating is cured, the water-soluble organic amine is removed by washing and erosion to absorb water to form micro-droplets, and a micron-scale microstructure surface antifouling material is prepared. .

Abstract

The invention belongs to the technical field of marine biofouling protection, and relates to a microstructure surface antifouling material and a preparation method thereof. Amine is the main raw material, among which hydroxyl-terminated polydimethylsiloxane is the main material for surface microstructure preparation, water-soluble organic amine is the erosion particle, and acrylonitrile-grafted silicone resin is the coating agent for the erosion particle. The surface microstructure is constructed by the self-assembly of branched silicone resin and water-soluble organic amine, and the antifouling purpose is achieved by using the microstructure surface to contaminate biological larvae, spores with less effective attachment area and weak attachment; no cuprous oxide, sulfur Antifouling agents such as cuprous cyanate and organotin have no destructive effects on the marine ecological environment, and can be widely used in marine biofouling protection on the surface of marine engineering facilities and structures such as docks, drilling platforms, piers, piles, etc. Better potential economic benefits.

Description

Technical field: [0001] The invention belongs to the technical field of protection against marine biological fouling, and in particular relates to a microstructure surface antifouling material and a preparation method thereof. The effective adhesion area of ​​fouling biological larvae or spores on the microstructure surface is small and the adhesion is not firm. Preparation of surface microstructure antifouling materials by particle regulation. 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 biofouling seriously affects the speed of ships, increases fuel consumption, and damages ship accessories and structures, seriously affecting navigation economy. Safety and security, measures must be taken to prevent it. Marine antifouling coatings have experienced a development process from toxic to environmentally friendly, short-...
