Preparation method of marine microorganism antifouling coating

Abstract

The invention relates to a method for making a marine microorganism antifouling paint by a marine microorganism fermentation product. The method realizes that bio-material is utilized to prepare the antifouling paint which prevents halobios from being attached; the invention belonging to the biological fouling protection technical field comprises three processing steps of preparing antifouling microorganism, antifouling protease and microorganism antifouling paint; firstly, barnacle and mussel are treated to a homogenate; the homogenate is taken out and put on a liquid substrate agar plate; the antifouling microorganism is obtained by lineation, separation and cultivation; secondly, the microorganism is conducted to a liquid seed substrate by a bevel substrate and cultivated in a fermentation substrate; a target active matter antifouling protease is obtained through the treatments of decompression, refrigeration and drying; finally, rosin is added to an alloprene solution and evenly stirred, then swell soil is added to the mixed solution and evenly stirred by electromotion; the active matter antifouling protease is added and evenly mixed, thereby obtaining the microorganism antifouling paint. The method for making the marine microorganism antifouling paint by the marine microorganism fermentation product has simple process course, low production cost, good antifouling effect and no environmental pollution.

Description

Technical field: The invention relates to a method for preparing a marine microbial antifouling paint by applying a novel marine microbial fermentation product to the field of marine antifouling. The method can realize the preparation of an antifouling coating for preventing marine organisms from adhering by using biological raw materials, and belongs to the technical field of biological fouling protection. Background technique: There are a large number of fouling organisms in seawater, such as mussels, barnacles, and seaweeds. These marine organisms will attach to the ship's hull, seawater cooling piping, and even sonar. This phenomenon is collectively called marine biofouling. Marine biofouling will increase the navigation resistance of ships, reduce the heat transfer efficiency of seawater cooling systems, and cause sonar performance failures, which seriously affect the maneuverability and safety of ships. Therefore, it is of great significance to take measures to preven...

However, because organic tin will cause serious pollution to the marine environment and cause genetic variation in marine organisms, the International Maritime Organization has passed a resolution requiring that organic tin be completely banned by 2008.

Polished cuprous oxide antifouling paint has become the mainstream of the existing technology. Although it meets the current environmental protection requirements, copper elements will accumulate in large quantities in the ocean, especially in harbors, resulting in the death of a large number of organisms such as seaweed, thereby destroying the ecology. balance, so eventually it will also be disabled
