Preparing method and application of carbon nanotube assembling capsaicin repellent biological anti-fouling marine paint

Abstract

The invention discloses a preparing method of carbon nanotube assembling capsaicin repellent biological anti-fouling marine paint. The method includes the steps of activating carbon nanotubes throughnitric acid and stearic acid, conducting polymerization with trifluoroethyl methacrylate as the monomer under the effect of an initiator to obtain a polyester emulsion doped with the carbon nanotubes,and dispersing a capsaicin acetone solution in the polyester emulsion. The intercalation and assembly and the slow-release effect of capsaicin between the carbon nanotubes and the affinity effect ofthe capsaicin and boat bottom steel plates are realized, the fastness of the boat bottom paint is improved, and the slow-release service life of the boat bottom paint is prolonged. The capsaicin is modified, then the capsaicin and the carbon nanotubes are assembled to form effective components, and the biological repelling and anti-corrosion effect of the long-service-life capsaicin can be realized.

Description

technical field

[0001] The invention belongs to the field of marine anticorrosion, and in particular relates to a preparation method and an application of a capsaicin repellent biological antifouling marine paint assembled with carbon nanotubes (multi-wall). Background technique

[0002] As we all know, the attachment of marine organisms to the surface of a ship will not only significantly increase the mass of the hull, increase navigation resistance, reduce the speed of the ship, thereby increasing fuel consumption, but also accelerate the corrosion of the ship's bottom and shorten the service life. In order to reduce the harm of marine organisms and prevent marine organisms from fouling ships, people have studied a variety of antifouling technologies. In the past few decades, compounds such as mercury and arsenic were used to formulate antifouling coatings in the early stage, but they were eliminated due to the toxicity of these substances and polluted the marine environme...
