example 1

[0024] Take marine plants and wash them twice, put them into a beater, crush them and beat them for 20 minutes to obtain a beating solution; mix the beating solution and absolute ethanol at a mass ratio of 1:10, put them into a flash extractor, and extract at 60°C for 10 minutes. Filter to obtain filter residue and extract, combine extract after filter residue is repeatedly extracted 2 times, place the combined extract in a flash concentrator and concentrate to 20% of the volume of the stock solution to obtain a concentrated solution; get 3g capsaicin, 10g coral reef, Put 30g of expanded vermiculite into a grinder and grind for 30min, cross a 100-mesh sieve to obtain a composite powder, get 20g of the composite powder and add it to 100g of concentrated liquid, stir at 300r / min for 15h to obtain a composite feed liquid; mix the composite feed liquid, Add 3g gelatin and 1g silane coupling agent KH-602 into 300g mass fraction of 1% chitosan solution, stir at 300r / min for 3h to obt...

example 2

[0027] Take marine plants and wash them twice, put them into a beater, crush and beat them for 25 minutes to obtain a beating solution; mix the beating solution and absolute ethanol at a mass ratio of 1:12, put them into a flash extractor, and extract at 65°C for 12 minutes. Filter to obtain filter residue and extract, combine extract after filter residue is repeatedly extracted 2 times, place the combined extract in a flash concentrator and concentrate to 25% of the volume of the stock solution to obtain a concentrated solution; get 4g capsaicin, 15g coral reef, 40g of expanded vermiculite is packed into a grinder and ground for 35min, and crossed a 100 mesh sieve to obtain a composite powder. Get 25g of the composite powder and add it to 150g of concentrated liquid, and stir at 350r / min for 17h to obtain a composite feed liquid; the composite feed liquid, Add 4g of gelatin and 1.5g of silane coupling agent KH-602 into 400g of chitosan solution with a mass fraction of 1%, and ...

example 3

[0029]The marine plants were washed with water for 3 times, put into a beater, crushed and beaten for 30 minutes to obtain a beating liquid; the beating liquid was mixed with anhydrous ethanol at a mass ratio of 1:15, put into a flash extractor, and extracted at 70°C for 15 minutes. Filter to obtain filter residue and extract, combine extract after filter residue is repeatedly extracted 3 times, place the combined extract in a flash concentrator and concentrate to 30% of the volume of the stock solution to obtain a concentrated solution; get 5g capsaicin, 20g coral reef, Put 50g of expanded vermiculite into a grinder and grind for 40min, pass through a 100-mesh sieve to obtain composite powder, get 30g of composite powder and add it to 200g concentrated liquid, stir at 400r / min for 20h to obtain composite liquid; 5g gelatin, 2g silane coupling agent KH-602, add 500g mass fraction of 1% chitosan solution, stir at 400r / min for 3-5h to obtain a mixture, put the mixture into a cent...

Abstract

The invention relates to environment-friendly anticorrosive coating for ships and a preparation method thereof and belongs to the technical field of anticorrosive coatings. Secretion of marine plants is extracted and is cooperated with capsaicine and coral reefs to serve as a natural biological anti-fouling agent; the attachment of bacteria and acorn barnacle is inhibited through actions of anaesthesia, bacterium-resisting, growth inhibition, insect-killing and the like and fouling organisms are repelled; the environment-friendly anticorrosive coating has efficient anti-fouling capabilities, is safe and has no toxin; expanded vermiculite has characteristics that a lamellar structure is similar to montmorillonite and the specific surface area, lamellar exchange density and chemical inertness are higher than those of the montmorillonite, and the expanded vermiculite is used for adsorbing the natural biological anti-fouling agent between layers and gelatin and chitosan are used for carrying out cross-linking sealing so that the slow release aim is realized; the natural biological anti-fouling agent and inorganic filling are combined, so that the biological corrosion prevention effect is combined with the shielding effect and the anticorrosive capability of a coating layer is effectively improved.

Description

technical field [0001] The invention relates to a marine environment-friendly anti-corrosion coating and a preparation method thereof, belonging to the technical field of anti-corrosion coatings. Background technique [0002] The ocean plays an increasingly important role in the economic construction and security of all countries, and the rational use and development of marine resources has become the common goal of cooperation and development of all countries. At present, it has gradually developed and formed a multi-level marine regional economy based on coastal tourism, fishery, port and transportation, and offshore oil and gas industry. More than 80% of international trade is carried out through marine transportation. In addition, there are a large number of marine resources in the ocean. Natural resources, so the development and use of the ocean has extremely broad prospects and significance. [0003] Corrosion has caused serious losses to global economic construction ...
