A certain amount of tetrabutyl titanate is slowly joined in APTES solution, solution is stirred simultaneously, then add appropriate absolute ethyl alcohol, wherein tetrabutyl titanate, APTES and absolute ethyl alcohol volume ratio are 15: 2.5: 10.Adding appropriate copper chloride solution and controlling its concentration is 3%, regulates PH to 3 ~ 4 with watery hydrochloric acid acid, being fully stirred to mixed liquor to not being suspended thing, making bamboo wood mould anticorrisive agent.Bamboo wood sample is put into impregnating autoclave, pushes down sample with weight, vacuumize process, vacuum pressure controls as-0.098Mpa, pressurize 150min.Pour bamboo wood mould anticorrisive agent after release into, then impregnating autoclave is pressurized to 7MPa, pressurize 240min, then release.After dipping terminates, bamboo wood sample is shifted out impregnating autoclave, dabs off the liquid be attached on surface, mensuration of weighing liquid retention, then place it in 23 ± 2 DEG C, 1 week constant under relative humidity 65% and condition of normal pressure.
Process sample utilizes electro microscope energy spectrum (SEM-EDS) to characterize, and evaluates its leach resistance with reference to AWPA standard A WPA E11-07 " standard method that timber preservative leachability judges ".Result shows: the element such as main component titanium, copper of fungusproof anti-corrosion agent all enters in the structure such as cell membrane, conduit of process material; Turnover rate is only 8.9%, and leach resistance is good.
