Abstract

The invention relates to a kind of coating and its preparation, which particularly raltes to a kind of modified silicone acrylate / nanosilica SiO2 antifouling coatings with low surface energy and its preparation which are primarily used for the ship's antifouling and others. The coationg includes following components by weight ratio: 12~50% of modified silicone acrylate, 5~20% of nano - silica, 20~35% of Physical pigments and fillers, 0.1~1% of promoter, 20~60% of organic solvent. The surface coating has no toxic substances released depletion.

Description

Technical field: [0001] The present invention relates to a kind of coating and preparation method thereof, especially a kind of organosilicon modified acrylate / nanometer SiO 2 Low surface energy antifouling paint and its production method, the paint is mainly used for antifouling of ships, and can also be used for other. Background technique: [0002] The hull below the waterline has been soaked in seawater for a long time, and various marine organisms are often attached to its surface, which will bring troubles to the navigation of the ship, seriously affect the speed of the ship, waste energy, and at the same time cause damage to the ship and underwater facilities. Corrosion damage intensifies and shortens its service life. In order to solve the above problems, a layer of antifouling paint can be applied on the outer surface of the hull. Currently used antifouling coatings mainly rely on the release of toxic materials such as copper, arsenic, mercury, lead, and tin to pr...
