Background technology
With the growth developed rapidly with the size of population of agricultural, the throughput requirements of crops are higher and higher, thereupon
Insecticide dosage it is increasing.But most of insecticide is all harmful to human body, and the use of insecticide can be tight
Ghost image rings ecological environment, and remaining insecticide can also constantly be concentrated in biological chain, very harmful.Therefore, agricultural development with
Balance is obtained between ecological environment to be particularly important.
The use for a long time repeatedly of insecticide also results in the resistance to the action of a drug, and a kind of insecticide often must not after using a period of time
Without replacing, cause huge fund of scientific research and waste.
It is mostly not soluble in water or be slightly soluble in water in addition, preparing protodrug is mostly oily liquids, and this can directly affect medicine
Effect release, therefore how to improve its water solubility is also a current important R＆D direction.

Both are sufficiently mixed, titanium dioxide nanoparticle is loaded on the surface of nano zine oxide by electrostatic interaction, is received
Nano composite material；
(3) nanocomposite obtained by step (2) is added in hydrophilic solution obtained by step (1) and soaked 5~6 minutes, taken
Be dehydrated after going out, be dry, to obtain the final product.
Still more preferably, the mass ratio of polyvinyl alcohol and water is 1 in step (1):30~32.
Still more preferably, the specific method of step (2) is：
(21) positively charged nano zine oxide is added in Nanometer Titanium Dioxide Hydrosol according to the ratio of 3~4g/L,
Ultrasonic disperse 15~20 minutes so that negatively charged nano-titania particle is adsorbed onto positively charged completely in the hydrosol
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：When vacuum drying 8~12 is small.
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, when standing 1 is small, obtains nanometer two
The titanium oxide hydrosol；Wherein, the molar ratio of butyl titanate, chelating agent and water is 1:6:93, 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, in step (3), it 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
Load 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 insecticide integrally carries positive charge, and the electric 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, will not
Pollute environment.
2nd, insecticide of the invention is powder, it carries hydrophilic radical, soluble easily in water, in that context it may be convenient to water dissolved dilution
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 cause insecticide to produce
The insecticidal effect of product is deteriorated.
