Sophoramine insect protected missible oil, sophoramine Mothproof fabric and preparation method thereof
Technical field
The present invention relates to a kind of fabric and preparation method thereof, relate in particular to sophoramine insect protected missible oil, sophoramine Mothproof fabric and preparation method thereof.
Background technology
Mosquito sucks human blood, spreads disease, serious harm human health.For a long time, people use several different methods to control mosquito, and all kinds of chemical insecticides are effective and efficiency time is long to mosquito control, in the sick control of mosquito matchmaker of certain areas, play the important and pivotal role.In people's daily life, also play at present irreplaceable effect, but organic synthesis insecticide is in efficient insecticide, has also left over many problems.Facts have proved, along with insecticide is a large amount of and use chronically, particularly insecticide is in a large number for preventing and treating pest, and the pesticide resistance degree of mosquito is more and more serious, and diffusion rapidly, and pesticide pollution environment and the impact on balance of nature thereof, be also growing on and on.They all become the outstanding problem in modern mosquito control.These factors impel people seek environmentally safe, be easy to degrade and there is the insecticide of selecting toxicity.In recent years, researcher drops into a large amount of human and material resources trials from natural products both at home and abroad, particularly from plant, find bioactivator with instead of chemical insecticide, the secondary metabolites that has now found that some plant corpus has positive effect in mosquito control, and has person poultry safety, is difficult for developing immunity to drugs, in natural environment, be easy to the feature of degraded.
Summary of the invention
For above shortcomings in prior art, one of technical problem to be solved by this invention provides a kind of sophoramine insect protected missible oil.
Two of technical problem to be solved by this invention is to provide a kind of preparation method of sophoramine Mothproof fabric.
Three of technical problem to be solved by this invention provides a kind of sophoramine Mothproof fabric.
The present invention seeks to be achieved through the following technical solutions:
A sophoramine insect protected missible oil, is comprised of following compositions in weight percentage: pyrethroid 5-15%, and sophoramine 2-4%, emulsifier 8-15%, surplus is organic solvent.
