Abstract
The invention discloses a nanometer type pesticide which is combined by components in parts by weight as follows: 10-20 parts of cyhalothrin, 20-30 parts of a nanometer inorganic material, 1-10 parts of a solvent, 5-15 parts of a surfactant and 50-60 parts of water. According to the nanometer type pesticide, a peculiar physical chemical property of the nanometer material is adopted and introduced into the hygienic pesticide, so that biological activity of an organic pesticide can be improved effectively, residue of the hygienic pesticide in the environment can be reduced, and environment protection is facilitated. The nanometer type pesticide can be widely applied to the field of agricultural production.
Description
Technical field
The invention belongs to chemical material field, relate to a kind of Nano type insecticide.
Background technology
Nanosecond science and technology are the theme science in forward position in 2l century leading science, and nanomaterials and nanotechnology is subject branch most active in nanosecond science and technology field, that research contents is very abundant.Nano material is applied in insecticide, after nano material and insecticide are integrated by chemical bond, because particle diameter is little, specific surface area is large, large to the compatibility of target tissue, after dispenser anelasticity and with tissue time of contact, contact area all greatly increase, thereby can improve the bioavilability of insecticide, reduce toxicity, reduce dosing.On the other hand, because the metal, nonmetal oxide, organic polymer of introducing nanometer are as functional material, it is much bigger that the more general material of these nano materials absorbs sunlight intensity, photocatalytic degradation, oxidation, hydrolysis insecticide, the degraded of acceleration of killing agent in environment, is degraded to nontoxic inorganic matter by poisonous organic insecticide.
In recent years, composite nano-granule medicine obtains extensive concern at medical domain, and nano particle is made to medicine and genophore, carries targeted molecular simultaneously, has target, controlled-release function, to improve drug effect to realizing pharmaceutical carrier.In the research of pesticide nanoparticle, generally adopt NC Development, Inc. of the phase inversion microemulsion method ，Ru U.S. adopted this method system each decis micro emulsion, the distribution of particles of its decis is between 10～200nm.Hunan Chemical Research Institute adopts this method to prepare chlorfenapyr micro emulsion, and the size distribution of its chlorfenapyr is at 10～200nm.But in hygienic insecticide, also do not adopt so far nanometer technology, without nanometer formulation.
Summary of the invention
Technical problem to be solved by this invention is to provide the Nano type insecticide that a kind of raw material is cheap, applied widely, medicament residue is few and insecticidal effect is definite.
For solving above technical problem, a kind of Nano type insecticide of the present invention, described Nano type insecticide is to be combined by cyhalothrin, nano inorganic material, solvent, surfactant and water, the weight portion of each component is as follows:
Above-mentioned nano inorganic material is titanium dioxide nano thread.
Above-mentioned surfactant is one or more in sodium laurate, glycerine, sorbierite, polyoxyethylene nonylphenol ether.
Above-mentioned solvent is ethanol or acetone.
Above-mentioned water is deionized water.
For further improving insecticidal properties, the weight portion of each component is as follows:
Compared with prior art, the beneficial effect that the present invention has is:
The present invention adopts the special physicochemical property of nano material, is introduced in hygienic insecticide, can effectively improve the biologically active of organic agricultural chemicals, reduces residual in environment of hygienic insecticide, is conducive to environmental protection.The present invention can be widely used in agricultural production.
