Abstract
The invention provides an incense coil. An active ingredient of the incense coil is an ester compound with the structural formula (1) as shown in the specification. A content of the ester compound in the incense coil is 0.8-1.5%, and the incense coil is prepared by coating an incense coil substrate with the ester compound and a hydrocarbon solvent after mixing. The incense coil has a good control effect on mosquitoes and flies, and is mainly used for indoor domestic hygiene pest killing.
Description
Technical field
The present invention relates to a kind of health incense coil, specifically, is a kind of health incense coil containing transfluthrin compound.
Background technology
Incense coil be comparatively early use for driveing or a kind of mode of kill pests, join in base material after pyrethroid compound being mixed with liquid form and make.Due to traditional pyrethroid compound, as Prallethrin 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 insecticidal incense coil of better effects if.
Fluoro-3-(2, the 2-dichloroethylene of 2,3,5,6-tetra-)-2,2-dimethyl cyclopropane carboxylic acid's esters (transfluthrin).
（1）
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 incense coil of transfluthrin compound, be that the mixture of formula (1) transfluthrin compound and varsol is joined a kind of hygienic biocide incense coil of making in base material, compare with traditional incense coil and there is excellent insecticidal effect.
Above-mentioned purpose incense coil of the present invention, main active insecticidal components is formula (1) pyrethroid compound of 0.8-1.5% weight, is the mixture of formula (1) transfluthrin compound and varsol is joined the effective insecticidal incense coil of the one obtained in base material.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:
The present invention joins in base material after being mixed with varsol by ester compounds to make incense coil, then dries.The preferred content of ester compounds in incense coil is heavily 0.8%.
Solvent of the present invention is varsol, is preferably kerosene.
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.
The base material of described incense coil is made up of with one or more adhesives one or more inflammable substances, and wherein the weight ratio of inflammable substance and adhesive is 90:10 to 99.9:0.1.The example of inflammable substance comprises and is selected from wood powder, Dalmatian chrysanthemum extracts powder out, oranges and tangerines oil-bound distemper, palm fibre put oil-bound distemper, coconut shell powder or walnut parting plant drymeal, or is selected from the carbon dust of charcoal powder, activated carbon powder or coal dust, or their mixture; The polymer of conglutnin, shuttle methylcellulose or polyvinyl alcohol and composition thereof.
Described incense coil base material normally by mixing inflammable substance and adhesive, is mediated with water, prepared by shaping and oven dry.The shape of coiled mosquito-repellent incense base material does not limit, and can be plate-like or strip.The present invention usually uses diameter to be about the conventional coil shape base material that 12cm and thickness are 3-5mm in incense coil.
Health incense coil of the present invention can use according to a conventional method, that is, is lighted by health line spices of the present invention in the habitat (such as, family, office, stock barn) of insect or its adjacent domain.The burning of health line spices makes transfluthrin compound evaporate, thus prevents and treats the such as sanitary insect pest such as mosquito, fly.
