Abstract
The invention relates to a high-hardness organic silicon protective coating, a preparation method and the application thereof. The coating consists of the following components based on the parts by weight: 100 parts of component A, 0-900 parts of component B and 0.05-5 parts of component C; wherein, the component A consists of silanized or oligomeric-siliconized (methyl) hydroxyalkyl acrylate and silicon functional organosilicone compound, proportion by weight between the silanized or oligomeric-siliconized (methyl) hydroxyalkyl acrylate and silicon functional organosilicone compound is 100-10 : 0-90; component B is alcohol or the mixture of alcohol and water; and component C is photoinitiator. The components are coated on the surface of a substrate after being evenly mixed, and a lyophobic anticorrosive film with good stick force is prepared after the coating is irradiated by ultraviolet light; the hardness of a film coating pencil is larger than or equal to 6H, so that the coating has good surface protective property and wear resisting property. The invention can be applicable to surface lyophobic protective treatment of stone, ceramics, concrete, metope, glass, metal, wood and plastic as well as cultural relic protection or surface encapsulation of electronic components.
