Specific embodiment
Hereinafter, will be described in detail the present invention.Before doing so, it should be appreciated that in this specification and appended Claims used in term should not be construed as being limited to general sense and dictionary meanings, and inventor should allowed On the basis of the appropriate principle for defining term to carry out best interpretations, according to meaning corresponding with technical aspect of the invention and generally Thought explains.Therefore, description presented herein is not intended to limitation originally merely for the sake of the preferred embodiment for illustrating purpose The range of invention, it will thus be appreciated that without departing from the spirit and scope of the present invention, it can be obtained by it His equivalents or improved procedure.
Silver is using a kind of more mature material in antibiosis, and compared with conventional metals antibacterial agent, nano silver is showed Better bioactivity out.Core-shell structure SiO2The nano particle of@Ag, in outer layer SiO2Package under can play slow releasing function, prolong The long fungus-proof antisepsis time.Middle SiO according to the method for the present invention2@Ag nano particle is uniformly mixed with oil by physical method, is operated Simply, at low cost, environmentally friendly effective.And the SiO of nano-scale2@Ag and oil molecule can enter in bamboo culm wall, stablize attached Inside bamboo wood, effectively enhance bamboo wood long-acting mould-proof performance.SiO2@Ag is poor in bamboo material surface adhesive force, is using It is easy to run off in journey, but SiO2@Ag and the bamboo wood of oily mixed processing are in the SiO after dry heat treatment2@Ag can be uniform and stable Be fixed in oil film.Processing method of the present invention treated bamboo wood not only has permanent effective antimildew and antibacterial performance, but also Improve the wear-resisting property of bamboo wood.
Preferably, method according to the present invention, core-shell structure SiO described in step (2)2@Ag nanoparticle size Optional 40-500nm, preferably 40-100nm.As the core-shell structure SiO2@Ag nanoparticle size within this range when, can be with Realize core-shell structure SiO2Effective dispersion of@Ag nano particle, and be easier into the cell wall of bamboo wood, stabilization is attached to bamboo Inside material.As core-shell structure SiO2When the size of@Ag nano particle is less than 40nm, it is easy to happen reunion, even if improving ball mill Revolving speed be also relatively difficult to realize the dispersion of substantially uniformity；As core-shell structure SiO2When the size of@Ag nano particle is greater than 500nm, Although can relatively easily disperse, due to core-shell structure SiO2@Ag nano particle it is oversized, enter bamboo wood plant It is not easy to when tissue, needs subsequent longer soaking time, therefore not economical enough.
Preferably, method according to the present invention, core-shell structure SiO described in step (2)2@Ag nano particle and oil Mass fraction proportion can be 1-20:100, preferred mass match 5-10:100.As the core-shell structure SiO2@Ag nano particle When being less than 1:100 with the mass fraction of oil, i.e., nano-particle content is too low, although good dispersion may be implemented, subsequent leaching During bubble, since concentrations of nanoparticles is too low, the amount into the nano particle of bamboo wood is very little, and cannot effectively play anti-corrosion effect Fruit；As the core-shell structure SiO2When the mass fraction of@Ag nano particle and oil is greater than 20:100, i.e. nano-particle content mistake Height, then, nano particle difficulties in dispersion, rear extended meeting are largely deposited on bamboo material surface and are easy to fall off.
Following embodiment is enumerated only as the example of embodiment of the present invention, does not constitute any limit to the present invention System, it will be appreciated by those skilled in the art that modification in the range of without departing from essence and design of the invention each falls within the present invention Protection scope.Unless stated otherwise, reagent and instrument used in the following embodiment are commercially available product.
