Abstract

The invention discloses an environment-friendly marine antifouling coating which comprises the following raw materials in parts by weight: 20-45 parts of epoxy phenolic resin, 0.5-1 part of titanium dioxide, 1-10 parts of a biological antifouling agent, 5-10 parts of titanium white, 3-8 parts of kaolin, 8-15 parts of mica powder, 18-28 parts of a solvent, 0.05-1 part of an anti-settling agent and 0.05-1 part of a wetting dispersant. Capsaicine in the biological antifouling agent has a very good avoidance effect on marine organisms; sodium benzoate and gallotannic acid have effective adhesion inhibition effects on barnacles and have paralyzing effects on beetles; shogaol has a very good adhesion prevention effect on mussels and cannot injure mussels, and the adhesion prevention effect of the shogaol is 4 times that of copper sulfate; P-cinnamic acid sulfate has a very good adhesion inhibition effect on marine bacteria and the barnacles, cannot cause any injury to the marine organisms, and is pure natural and pollution-free.

Description

technical field [0001] The invention relates to an antifouling paint, in particular to an environment-friendly 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. Large-scale fouling can be further divided into soft fouling and hard fouling. Soft fouling refers to the fouling caused by organisms such as algae, bryozoans, sea squirts, and hydra. Fouling by organisms such as barnacles and oysters. 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...
