Abstract

The anti-fouling ship paint with low biological surface energy consists of low surface energy resin, biological extract micro capsule, nanometer titania, microporous silica and solvent. The present invention has biological extracts chitin, capsaicin as anti-fouling agent through micro capsule slow releasing treatment and nanometer modified low surface energy paint and multiple anti-fouling performances. The present invention has the advantages of self-cleaning performance, corrosion resistance, heat resistance, weather resistance, etc and is used for ship as well as bridge, marine engineering member, etc.

Description

Technical field: [0001] The present invention relates to antifouling coatings, especially marine antifouling coatings. Background technique [0002] There are about 2,000 kinds of periphytons in seas all over the world. The larvae and spores of these periphytons float and swim in the ocean. When they develop to a certain extent, they attach, settle and further reproduce on the bottom of ships. These biological attachments will increase the surface roughness of the bottom of the ship, reduce the speed of the ship, increase fuel consumption (up to 30%), and increase the resistance of seawater pipeline transportation. At the same time, these organisms will also secrete organic acids, making the bottom steel plate And the corrosion damage of underwater facilities is aggravated, and the service life is significantly shortened. In order to solve this problem, various marine antifouling coatings have emerged as the times require. Compounds such as copper, arsenic, cadmium, lead, ...
