Transparent organic silicon coating and preparation method thereof

The invention relates to a transparent organic silicon coating and a preparation method thereof. The transparent organic silicon coating is characterized by comprising the following components in percentage by mass: 70-80% of a silane modified polyether composition, 2-8% of a silane coupling agent compound, 4-7% of MT silicon resin, 4-22% of silicone oil with the viscosity of 1-5 cst and 1-2% of an anti-UV auxiliary agent; the silane modified polyether composition is composed of methyl diethoxy silane modified polyether, ethoxy dimethyl silane modified polyether, methyl dimethoxy silane modified polyether and methoxy dimethyl silane modified polyether; and the silane coupling agent compound is composed of vinyl trimethoxy silane, 3-amino propyl trimethoxy silane and tetraethoxysilane according to the mass ratio of (3-4):(3-5):(1-4). The preparation method has the advantages of simple process steps and no pollution to the environment, and the obtained product has the advantages of transparency, good weather re
