Embodiment 1

[0035] This embodiment provides a kind of preparation method of antifouling agent, specifically comprises the following steps:

[0036] 1. Disperse 10 g of hydrotalcite in 500 mL of deionized water, stir for 3 hours, and sonicate for 30 minutes to obtain a hydrotalcite suspension;

[0037] 2. Add 1 g of capsaicin into 300 mL of acetic acid solution with a volume fraction of 1%, stir for 6 hours, and adjust the pH value of the solution to 5.0 with 1 mol / L NaOH to obtain a capsaicin solution;

[0038] 3. Slowly add the capsaicin solution to the hydrotalcite suspension, stir at 45°C for 6 hours, then add 3g of crystalline graphite oxide; continue stirring at 60°C for 10 hours, finally wash with distilled water, filter, and vacuum dry to obtain capsaicin Intercalated hydrotalcite / oxidized crystalline graphite composite antifouling agent.

Embodiment 2

[0040] This embodiment provides an antifouling strippable coating and a preparation method thereof, specifically comprising the following steps:

[0041] 1. Weigh each raw material according to the following ratio:

Abstract

The invention provides an antifouling peelable coating composition and a preparation method and an application thereof. The antifouling peelable coating composition comprises alcohol soluble resin, anorganic solvent, an active nano inorganic filler, a wetting dispersant, a levelling agent, a defoaming agent and a plasticizer and is simultaneously added with a self-made capsaicin intercalated hydrotalcite / oxidized crystalline graphite composite antifouling agent. The antifouling peelable coating composition provided by the invention has the beneficial effects that when the coating compositionis applied to an abalone breeding box, by adopting the intercalation composite technology, the antifouling cycle of the coating is prolonged and the antifouling effect is improved; and by adopting thepeeling technology, even if benthos are adsorbed on the breeding box after the failure of the antifouling effect of the coating, the benthos can be peeled off together with the coating to ensure thatthe breeding box is still brand new and has the advantages of double fail-safe and the like.

Description

technical field [0001] The invention relates to an antifouling peelable coating composition, a preparation method and application thereof, and belongs to the technical field of antifouling adhesives. Background technique [0002] Most of the existing abalone breeding boxes are square breeding boxes or circular breeding boxes, which are generally formed by direct injection molding of polyolefin resins. Since the abalone breeding cycle is generally 1-2 years, the abalone breeding box needs to be placed in seawater for a long time, and it is easy to be fouled by marine organisms such as shellfish and algae. A large number of marine attached organisms will affect the water quality and Water-soluble oxygen brings impact, causing the death of farmed abalone. In addition, due to the serious fouling and adhesion during the breeding process, it is difficult to clean up, resulting in an increase in the number of times the farmers replace the breeding boxes, wasting manpower and finan...
