Nanometer marine antifouling paint

Abstract

The invention relates to the technical field of marine antifouling coating and discloses nano marine antifouling coating. The nano marine antifouling coating is prepared from the following componentsin parts by weight: 1-5 parts of nano silicon dioxide peptized particles, 1-5 parts of nano titanium dioxide, 10-50 parts of acrylic resin, 10-20 parts of a filler, 15-30 parts of an environment-friendly antifouling agent, 5-8 parts of a methyl acyloxy propyl trimethoxy silane coupling agent, 5-8 parts of acrylic acid, 5-8 parts of organic fluorine, 10-30 parts of a solvent and 6-8 parts of auxiliaries. A coating formed by the nano marine antifouling coating has high hardness, good thermal stability and optical properties, has a good antibacterial effect, has an inhibition effect on metals attached to marine bacteria growth, and solves the problems of low hardness and no antibacterial effect of coatings formed by existing marine antifouling coating.

Description

technical field [0001] The invention relates to the technical field of marine antifouling paint, in particular to a nanometer marine antifouling 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, optical instruments and other offshore equipment, and increase the burden on offshore oil and gas exploration platforms. Accelerated metal corrosion and other serious hazards, resulting in huge losses in marine military activities, marine ...
