Ancient architecture timber structure waterproof anticorrosive paint and preparation method thereof

The invention relates to ancient architecture timber structure waterproof anticorrosive paint and a preparation method thereof, and belongs to the technical field of timber protection. A timber impregnating compound is prepared from a mixed solution of triethylamine trihydrogen fluoride and ammonium hexafluorophosphate; ionization ions in the mixed solution of triethylamine trihydrofluoride and ammonium hexafluorophosphate can penetrate into an amorphous region of wood fibers to access to the outer surface of a crystallization zone; by destroying hydrogen bond bonding between water and cellulose, swelling in a cellulose amorphous region occurs, which further facilitates permeation of the waterproof anticorrosive paint; meanwhile, tetraethoxysilane and copper ions are compounded to preparethe silica gel immobilized copper mildew preventive, and after the coating permeates into the wood, the silica gel can firmly fix metal copper ions in the timber structure material, the protective performance of the ancient a
