Modified silica ceramic resin and preparation method thereof

The invention discloses modified silica ceramic resin and a preparation method thereof, the modified silica ceramic resin comprises 40-50 parts by weight of silicon resin, 50-70 parts by weight of waterborne epoxy resin and 1-3 parts by weight of boric acid doped polyaniline, the silicon resin is obtained by jointly hydrolyzing tetraethoxysilane and gamma-methacryloxypropyltrimethoxysilane and then adding styrene for crosslinking, and the boric acid doped polyaniline is synthesized by using boric acid as a doping agent and ammonium persulfate as an initiator through a chemical oxidation method. The waterborne epoxy resin and the silicon resin are compounded, a waterborne epoxy coating system has the advantages of being high in adhesive force, excellent in coating corrosion resistance and good in construction performance, and the defects of the silicon resin in the aspects of curability, adhesion, solvent resistance, mechanical strength and the like can be perfectly overcome; the corrosion ...
