Abstract
The invention provides a pyrethroid incense stick. An active ingredient of the incense stick is an ester compound with the structural formula (1) as shown in the specification. A content of the ester compound in the incense stick is 0.8-1.5%, and the effective incense stick is prepared by coating an incense stick substrate with the ester compound and a hydrocarbon solvent after mixing. The incense stick has a good control effect on mosquitoes and flies.
Description
Technical field
The invention provides a kind of pyrethroid health line spices, specifically, is a kind of health line spices containing transfluthrin compound.
Background technology
At present, pyrethroid line spices are that hygienic biocide uses comparatively widely wherein one, are be coated to the effective health line spices of the one that line spices base material obtains by after ester compounds and varsol mixing.Due to traditional pyrethroid compound, as cholrempenthrin etc., containing certain excitant and toxicity, and be a kind of single desinsection mode, insecticidal effect usually shows deficiency, therefore will seek a kind of hygienic biocide line spices of better effects if.
Fluoro-3-(2, the 2-dichloroethylene of 2,3,5,6-tetra-)-2,2-dimethyl cyclopropane carboxylic acid's esters, are called for short transfluthrin.Structural formula is:
Transfluthrin, compares with traditional pyrethroid, and its toxicity is low, nonirritant and mosquitos and flies is double controls, effective, can well substitute traditional pyrethroid.
Summary of the invention
The object of the invention is: provide a kind of main active to be the health line spices of transfluthrin compound, be be coated to the effective health line spices of the one that line spices base material obtains by after transfluthrin compound and varsol mixing, compare with traditional line spices and there is excellent insecticidal effect.
Above-mentioned purpose line spices of the present invention, main active insecticidal components is formula (1) pyrethroid compound of 0.8-1.5% weight, is to be coated to the effective health line spices of the one that line spices base material obtains by after transfluthrin compound and varsol mixing.Described ester compounds is any one or 2-3 kind mixture of following stereoisomer:
Fluoro-3-(2, the 2-dichloroethylene of 2,3,5,6-tetra-)-2,2-dimethyl cyclopropane carboxylic acid's esters:
(+) 2,3,5,6-tetra-fluoro-1R, cis-3-(2,2-dichloroethylene)-2,2-dimethyl cyclopropane carboxylic acid's esters:
(+) 2,3,5,6-tetra-fluoro-1R, trans-3-(2,2-dichloroethylene)-2,2-dimethyl cyclopropane carboxylic acid's esters:
Health line spices of the present invention solvent used is varsol, and be preferably kerosene, the preferred content of ester compounds in line spices is 0.8% weight.
Also can containing surfactant or other auxiliary agents as the mixture of one or more in aromatic, colouring agent, stabilizing agent and preservative in the mixture of formula (1) compound and varsol.Surfactant comprises alkyl sulfate, alkylsulfonate, alkyl aromatic sulfonate, polyoxyalkylene alkyl, polyoxyalkylene alkyl aromatic ether, polyoxyalkylene styrylphenyl ether, polyol ester and sugar alcohol derivant.
Also can add one or more boiling points at the di-t-butyl-phenol stabilizing agent of 250 DEG C or more, the stability not only when ageing stability but also fumigation also significantly strengthens, and the raising for volatile performance has contribution.
Line spices base material is normally made up of one or more combustion adjuvants and one or more adhesives.The example of combustion adjuvant comprises the plant drymeal of such as wood powder, citrus peel meal, palm oil-bound distemper, coconut shell powder and walnut parting; The such as powdered carbon of charcoal powder, activated carbon powder and coal dust; And their mixture.The example of adhesive comprises the polymer of such as starch (such as tapioca, corn starch, wheaten starch), casein, methylcellulose, carboxymethyl cellulose and polyvinyl alcohol and composition thereof.
Line spices base material is normally prepared by the following method: mixed with adhesive by combustion adjuvant, and optional and water is kneaded, shaping and dry oven dry.
The method of the mixture of coating type (1) compound and hydrocarbon solvent is by carrying out with under type: be evenly coated on line spices base material with brush by mixture, is evenly added drop-wise to by mixture on line spices base material or by mixture even spraying on line spices base material.Mixture is being coated to after on line spices base material, is making incense stick for insect disinfestation dry.This dry run is carried out 5-35 DEG C of placement by making incense stick for insect disinfestation for 0.1-10 hour.
Health line spices of the present invention can in the habitat of insect (such as, family, office, stock barn) or its adjacent domain light, burning makes the transfluthrin on line spices volatilize, and after transfluthrin reaches finite concentration in air, can reach and drive or the effect of kill pests.
Embodiment
Explain technical scheme of the present invention and effect in detail by the form of embodiment below, but the present invention is not limited to following examples.
Prepare line spices base material
In the starch of 99.99 weight portions and the mixture of wood powder (4:3), add the water of 120 weight portions and mediate shaping, then drying is dried into line spices shape line spices base material (diameter 11.8cm, thick 4mm, heavy 25g).
