Abstract

The invention relates to low surface energy fluorine carbon antifouling paint. It belongs to sea antifouling paint field. It is mixed by the first and second component with 12-20:1 weight ratio. The first component is formed the following weight percentage matter: fluorocarbon resin 30-60%, zinc oxide 5-20%, pigment 1-15%, anti-fouling compound 0.1-45%, organic silicon compound 0.1-10%, and auxiliary agent 0.1-2%. The second is aliphatics and aromatic curing agent. The invention mixes the first and second component before painting dressing, then processes room temperature cross linking solidifying to make fluorine carbon paint have low surface energy and high contact angle with water after film forming, and realize synergism anti fouling with antifouling compound to reach the effect of preventing fouling by marine organism.

Description

technical field [0001] The invention relates to a fluorocarbon antifouling paint with low surface energy, which belongs to the field of marine antifouling paint. Background technique [0002] As a special functional protective coating, marine antifouling coatings are used to coat the bottom of ships, marine structures, offshore oil platforms, submarine oil pipelines, etc. to prevent marine organisms from attaching and fouling. [0003] Low surface energy antifouling coatings, the antifouling principle is to develop coatings with unique surface properties, making it difficult for marine organisms to attach to them, even if the adhesion is not firm, the adhesion interface is very weak, and it is easy to fall off under the action of water flow or other external forces. Traditional toxic antifouling coatings generally only have an inhibitory effect on some marine organisms, and with the continuous release of toxic substances, their antifouling effect gradually declines. Low sur...
