Silicon-hydrogen bond terminated multifunctional hyperbranched organic silicon resin and preparation method thereof

The invention discloses a silicon-hydrogen bond-terminated multifunctional hyperbranched organic silicon resin and a preparation method thereof, and the preparation method comprises the following steps: hydrolyzing an alkyl-containing siloxane monomer or a functional group-containing siloxane monomer to form a nucleus, condensing, growing, terminating and purifying to obtain the silicon-hydrogen bond-terminated multifunctional hyperbranched organic silicon resin. The obtained organic silicon resin has a highly branched structure, the means of introducing functional groups is convenient and rapid, the preparation process is simple, the cost is low, the functional groups contained in the structure can be simply and rapidly adjusted, the raw materials are cheap and easy to obtain, and the influence of other functional groups on the activity of silicon-hydrogen bonds is small; the hyperbranched silicone oil is prepared from siloxane containing alkyl or functional groups and siloxane containing silicon-hydrogen bo
