Application of osthole in preparation of marine antifouling paint

Abstract

The invention relates to application of osthole, and particularly provides application of osthole in the preparation of a marine antifouling paint. The molecular formula of the osthole is C15H16O3, the molecular weight is 244.29, and the chemical name is 7-methoxyl-8-isopentenyl coumarin. The osthole has obvious inhibiting effects on marine micro fouling organisms, marine macro soft fouling organisms and marine macro hard fouling organisms, indicates high-efficiency and broad-spectrum antifouling activities, and is widely applied to the preparation of the marine antifouling paint. Because the osthole is a natural compound, the marine antifouling composition prepared from the osthole does not contain toxic heavy metal compounds and can not pollute the environment. The osthole extraction and preparation process is simple and mature, thereby being beneficial to the popularization and application of the osthole in the preparation of the marine antifouling paint.

Description

Application of osthole in preparation of marine antifouling paint technical field The invention relates to the application of osthole, in particular to the application of osthole in preparing marine antifouling paint. Background technique 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 breed...
