Description
Technical Field
The invention belongs to the technical field of marine antifouling paints and underwater paints, and particularly relates to an organosilicon marine antifouling paint capable of keeping long and high adhesion underwater, a cured coating thereof and a preparation method thereof.
Background
The indiscriminate adhesion of marine fouling organisms, which causes a series of problems of corrosion, increase of self weight, increase of fuel consumption and the like of facilities, is a major problem facing the development of marine transportation industry in countries in the world at present. At present, the international common way is to apply antifouling paints. In 2008, International Maritime Organization (IMO) and shipping departments and organizations of various countries pass the rules and systems for developing environment-friendly marine antifouling paint. Therefore, the environment-friendly marine antifouling paint is developed internationally, namely, the damage of the release of toxic and harmful chemicals to the marine ecological environment is avoided while the adhesion of fouling organisms is effectively inhibited.
The antifouling mechanism of the organic silicon marine antifouling paint is mainly that the surface energy of a coating is low, fouling organisms are difficult to adhere, and the related paint has a great development and application prospect at present. However, also due to the low surface energy characteristics of silicone resins, cured silicone coatings tend to be difficult to adhere to polar metal substrates. This low adhesion to the metal substrate or the corresponding intermediate coating can lead to large-area peeling off of the corresponding coating during use, in particular during long-term service in (sea) water. The problem of easy falling caused by low cohesive force severely limits the wide application range of the relevant organic silicon marine antifouling paint.
