The surface of nano zine oxide；
(22) adsorbed product is centrifugally separating to obtain, is then washed 2~3 times with absolute ethyl alcohol, it is dry, obtain nano combined material
Material.
Still more preferably, in step (22), dry process conditions are：Vacuum drying 8~12 hours.
Still more preferably, the preparation method of Nanometer Titanium Dioxide Hydrosol is as follows：By butyl titanate and chelating agent
It is mixed 20~30 minutes, is then slowly added dropwise into the mixed solution of catalyst and water, stand 1 hour, obtain nanometer two
The titanium oxide hydrosol；Wherein, the molar ratio of butyl titanate, chelating agent and water is 1: 6: 93, and catalyst accounts for whole system gross weight
The 3.2% of amount.
Still more preferably, the chelating agent and catalyst are acetic acid.
Still more preferably, in step (3), the mass ratio of nanocomposite and hydrophilic solution is 1: 7~8.
Still more preferably, it in step (3), is dehydrated using centrifugal process, drying means is natural air drying.
The beneficial effects of the invention are as follows：
1st, disinsection method of the invention belongs to physical desinsection, makes negative electrical charge titanium dioxide nanoparticle by electrostatic interaction
It loads on the surface of positive charge nano zine oxide, the reunion of nano particle can be avoided, be further introduced into the parent with positive charge
After water base group so that for insecticide integrally with positive charge, the charge itself carried using charged nanosize insecticide cuts pest worm
The phospholipid bilayer of body, and then pest is killed, it is nontoxic, compared with traditional insecticide, do not develop immunity to drugs, it will not
Pollute environment.
2nd, insecticide of the invention is powder, soluble easily in water, it may be convenient to be diluted with water dissolution with hydrophilic radical
After spray, give full play to desinsection drug effect.
3rd, insecticide of the invention is nanoscale, low-residual, it is ensured that food and ecological safety.
4th, for soaking time with 5~6 minutes, soaking time was too short, can not ensure in nanocomposite addition hydrophilic solution
Hydrophilic radical is sufficiently introduced into, and influences the negative charge amount and hydrophily of pesticide product；Long soaking time, itself is positively charged
Hydrophilic radical squeeze positively charged nano zine oxide, influence the stability of nanocomposite, and then insecticide is caused to produce
The insecticidal effect of product is deteriorated.
