Abstract
The invention discloses a marine antifouling nano paint, which is prepared from the following raw materials: epoxy phenolic resin, titanium dioxide, a nano biological antifouling agent, filler, an acetic acid, and glyceryl tristearate. Capsaicin in the nano-scale biological antifouling agent has a good approach-avoidance effect on marine organisms; tannic acid has an adhesion inhibition effect on barnacle and also has a paralysis function on the beetle; shogaol has strong ability of preventing adhesive ability of mussel. P-cinnamic acid sulfate has a strong adhesion inhibition effect on marine bacteria and barnacle, homarine can prevent adhesion of marine benthic diatom and barnacle, and diterpenes formamide has an effect of inhibiting the barnacle and shellfish larvae. The paint disclosed by the invention comprises a nano-scale pure natural biological antifouling agent, has the approach-avoidance effect on marine organisms, and destroys the adhesive ability of the marine organisms, so as to achieve the target of preventing and treating pollution. The marine antifouling nano paint does not generate any deleterious effect on the marine environment, is free of an injury to the marine organisms, and is purely natural and harmless.
Description
technical field [0001] The invention relates to an antifouling paint, in particular to a nano marine antifouling paint, which belongs to the technical field of paint. Background technique [0002] In the marine environment, when an object is immersed in seawater, micro-fouling occurs first on its surface, that is, micro-organisms such as bacteria attach to the surface of the object, and grow and reproduce on it; Larvae of vertebrates such as barnacles, mussels and sea squirts attach to surfaces in a process known as macrofouling. These marine fouling organisms adhere to the surface of artificial facilities in the sea, which will increase the navigation resistance of ships, block pipelines and breeding nets, affect the normal use of acoustic instruments and other offshore equipment, increase the burden on offshore oil and gas exploration platforms, and accelerate metal corrosion Serious hazards such as marine pollution, leading to huge losses in marine military activities, m...
