Nano marine antifouling paint

Abstract

The invention discloses a nano marine antifouling paint, which is composed of the following raw materials in parts by weight: 25 to 40 parts of epoxy phenolic resin, 0.5 to 1 part of titanium dioxide, 1 to 10 parts of nano biological antifouling agent, 20 to 45 parts of filling material, 3 to 8 parts of deionized water, 1 to 5 parts of binder, 1 to 5 parts of corrosion inhibitor, 13 to 20 parts of acetic acid, and 0.05 to 1 part of tristearin. The paint contains a nano grade pure natural biological antifouling agent, has a dispelling effect on marine organisms, is capable of destroying the attaching ability of marine organisms so as to prevent fouling, does not generate any toxic or harmful effect on marine environment, is harmless for the marine organisms, and is made of pure natural and harmless materials.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a nano marine antifouling coating. 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, marine transportation, industry and...

Problems solved by technology

Despite the persistent efforts of paint workers to meet new challenges, the speed of improvement in paint performance lags far behind the needs of social development

Some common problems of coatings and coatings, such as: separation and peeling of coatings and substrates, early blistering, corrosion damage, leakage of chemical media, chalking, fading, loss of gloss, easy scratches and wear, easy damage to mold and fungus growth , pollution, etc.; not only that, but also toxic substances such as heavy metals will escape into the water body during long-term use, which will pose a great threat to marine organisms and ecosystems
