[embodiment]
For make above-mentioned purpose of the present invention, feature and advantage can be more obviously understandable, does detailed explanation below in conjunction with the accompanying drawing specific embodiments of the invention.A lot of details have been set forth in the following description so that make much of the present invention.But the present invention can implement much to be different from alternate manner described here, and those skilled in the art can do similar improvement under the situation of intension of the present invention, so the present invention does not receive the restriction of following disclosed practical implementation.
The mildew resistant spraying agent of embodiment one; By weight percentage; Contain 0.02%～0.5% bacteriostatic activity material, 0.01%～1.5% nonionic surface active agent and 0.004%～0.25% porous, inorganic nano particle; Surplus is a water, wherein, and the distillation extraction thing that said bacteriostatic activity material is the fruit of a cubeb litsea tree, mustard, Chinese cassia tree, cassia bark and garlic.
The bacteriostatic activity material of present embodiment contains citral and cinnamic acid, and it adopts mainly antibacterial, mildew-resistant component of natural plant extracts conduct.Safe, nontoxic, environment and health are had no adverse effects.
The bacteriostatic activity material of present embodiment can be prepared by following method:
Fruit of a cubeb litsea tree fruit is made essential oil with steam distillation after drying, the essential oil after the distillation obtains litsea cubeba oil through the refining of fractionation appearance, and wherein citral content is 85%; Cassia oil and cinnamon oil are purchased in the perfumery, Jiangxi, and its cinnamic aldehyde content is 85%; Litsea cubeba oil, cinnamon oil, cassia oil are become addition product with bisulf iotate-treated, separate refining then with alkali again, promptly obtain above-mentioned bacteriostatic activity material.
Said nonionic surface active agent is preferably tween80 or Span20.
Said porous, inorganic nano particle is nano silicon, nano zine oxide or nano titanium oxide, and its particle diameter is 1～10 μ m.
This embodiment through the absorption of inorganic nanoparticles, utilizes the surfactant-dispersed technology to take from the bacteriostatic active ingredients of pure natural plant; Process long-acting mildew resistant spraying agent, can be used for body of wall, fabric, furniture etc.; Safety non-toxic, consumption is low, the fungistatic effect length of holding time.
The mildew resistant spraying agent of embodiment two; By weight percentage; Contain 0.02%～0.5% bacteriostatic activity material, 0.01%～1.5% nonionic surface active agent and 0.006%～0.25% porous polymer microsphere; Surplus is a water, wherein, and the distillation extraction thing that said bacteriostatic activity material is the fruit of a cubeb litsea tree, mustard, Chinese cassia tree, cassia bark and garlic.
