Embodiment

[0006] Embodiment: A kind of preparation method of marine antifouling paint, is made up of resin solution, plasticizer, filler and cuprous oxide, weight percent is 20-60, 1-20, 1-30 and 1-50, in 1000mL In a three-necked flask, add 2.9 g of methyl cellulose, 50 g of copper acetate, 5.8 g of potassium bromide, and 300 mL of water, stir well and heat up to 95 ° C, dissolve 8.5 g of potassium carbonate and 23.8 g of hydrazine hydrate in 200 mL of water, and Under stirring conditions, add it dropwise to the above-mentioned copper acetate solution. After the dropwise addition, continue to add aqueous sodium hydroxide solution (1mol / L) dropwise to the three-necked flask, adjust the pH value of the system to 5-7, and then keep warm 3. Continue to stir for 30 minutes to end the reaction. After standing still for 1 hour, a large number of yellow particles in the reaction system sank to the bottom of the bottle. After filtering and washing with water, dry it at 30-60°C to obtain cuprous o...

Abstract

The invention discloses a method for preparing a marine pollution prevention paint. The paint comprises the resin solution, the elasticizer, the filler and the copper-protoxide. The method comprises the following steps: adding carboxymethyl cellulose, copper acetate, potassium bromide, water in the three-hole flask; mixing and heating; dissolving potasium carbonate and hydrazine hydrate in the water; mixing; dropping in the copper acetate solution; dropping caustic soda solution in three-hole flask; adjusting pH value of the system; keeping the temperature; mixing; stewing; producing a good deal of yellow particles; filtering; cleaning; drying; getting cuprous oxide; vibrating the mixture of 40% elastic acrylic aqueous emulsion, chlorcosane, iron oxide red, gas phase silica dioxide and cuprous oxide in the oil paint oscillator; filtering with filter. The invention is provided with the simple production technology, the high oxidation resistance and the high pollution resistibility.

Description

technical field [0001] The invention relates to a preparation method of marine antifouling paint. Background technique [0002] Marine fouling organisms attach to various water facilities such as ships, offshore drilling platforms, buoys, marine aquaculture facilities, and marine detection instruments, which will slow down the ship's navigation speed and increase fuel costs, accelerate metal corrosion, and cause seawater pipelines and There are a series of problems such as blockage of breeding cages, imbalance of underwater facilities, and instrument failure. The best solution is to apply antifouling paint. Organotin compounds in self-polishing antifouling coatings can cause serious pollution to the environment and can affect human health through the food chain. Cuprous oxide is widely used in antifouling coatings. However, the dispersibility of cuprous oxide particles in the paint is not good enough, and it is easy to aggregate and settle; cuprous oxide is easily oxidize...
