Problems solved by technology

However, it is also because of the low surface energy properties of silicone resins that cured silicone coatings tend to have difficulty adhering to polar metal substrates
And this kind of low adhesion to the metal substrate or the corresponding intermediate connection paint will cause the corresponding coating to peel off in a large area during use, especially during long-term service in (sea) water.
The easy peeling problem caused by this low adhesion severely limits the wide range of applications of related silicone marine antifouling coatings

Abstract

The invention discloses an underwater high-adhesion organosilicone marine antifouling paint and a cured coating and a preparation method thereof. The coating subjected to ultraviolet curing shows an excellent hydrophobic effect on a seawater contact interface, and the hydrophobic effect is kept for a long time; the coating can be firmly bonded on a base material or epoxy intermediate paint contact interface by virtue of Van der Waals force and hydrogen bonds between thiourea groups and ether groups, and meanwhile, the synergistic effect of hydrophobic interaction and weak hydrogen bonds can ensure that the coating keeps a good bonding effect in a long-term underwater environment; and the coating can be widely applied to ocean ships, offshore oil drilling platforms, deep sea detection equipment, underwater long-term use equipment and the like, and is particularly suitable for facilities immersed in a seawater environment for a long time.

Description

technical field [0001] The invention belongs to the technical field of marine antifouling coatings and underwater coatings, and in particular relates to an organic silicon marine antifouling coating which maintains long-term high cohesive force underwater, a cured coating and a preparation method thereof. Background technique [0002] The indiscriminate adhesion of marine fouling organisms, which leads to a series of problems such as corrosion of facilities, increased self-weight, and increased fuel consumption, is a major problem facing the development of the marine transportation industry in countries around the world. At present, the common way in the world is to apply antifouling paint. In 2008, the International Maritime Organization (IMO) and the shipping departments and institutions of various countries adopted the rules and systems for the development of environmentally friendly marine antifouling coatings. Therefore, the international community is vigorously develo...
