Abstract
The invention discloses an electrothermal mosquito-repellent liquid. The electrothermal mosquito-repellent liquid comprises culicifuge medicine liquid and an evaporator core. The culicifuge medicine liquid comprises: 0.2 to 2 parts by weight of chlorine fluorine etofenprox as an effective component, 1 to 10 parts by weight of a stabilizing agent, 2 to 20 parts by weight of evaporation regulators and 67 to 96 parts by weight of an organic solvent. A preparation method of the electrothermal mosquito-repellent liquid comprises the following steps that: the organic solvent, the evaporation regulators, the chlorine fluorine etofenprox as an effective component, the stabilizing agent and an assistant are added into a stirred tank with stirring according to the weight part proportion; after being mixed uniformly, the mixture obtained the previous step is filtered and then is canned; and the evaporator core with a plunger is inserted into a can with the mixture. The present electrothermal mosquito-repellent liquid is superior to allethrin mosquito-repellent liquid and similar to tetrafluoro methothrin in mosquito repellent effects, and has usage amounts of effective component and organic solvent thus has a low production cost and a small impact on the environment.
Description
[technical field]
The present invention relates to a kind of mosquito liquid, relate in particular to higher a kind of mosquito liquid of cost performance and preparation method thereof.
[technical background]
Mosquito liquid is not singly to refer to a kind of soup, perhaps singly refers to a kind of apparatus, but the combination of a kind of soup, volatilization core, apparatus; But be not a kind of mechanically simple addition, the face that it involves is wider, and the factor of influence is more, so want to develop high, the ripe product not a duck soup of a kind of cost performance.Usually, if a company produces this product, the service behaviour of the electric heater of mosquito liquid and technical indicator are constant substantially, can improvedly mainly be mosquito liquid and two aspects of volatilization core.The mosquito liquid of existing market, its active ingredient are generally alkynes third chrysanthemum ester and tetrafluoro methothrin.Wherein the alkynes third chrysanthemum ester is through the application of more than ten years, and mosquito has produced certain pesticide resistance to it, thereby the used in amounts in mosquito liquid will strengthen, and causes the cost of mosquito liquid higher; Though and tetrafluoro methothrin drug effect is higher, its unit price is very high, and cost also is that cost performance is lower than higher.As the bigger solvent of usage amount in the mosquito liquid mosquito liquid, on the market most of usefulness be still the tetradecane hydrocarbon, comprise having of positive structure and isomery.The unit price of this solvent is higher, large usage quantity, and use cost is higher.In the preparation mosquito liquid of different service times, certain limitation is arranged.Phenomenon of rupture might take place in the used volatilization core of existing mosquito liquid on the market in transportation, influences product quality; In use, can produce certain clogging to the middle and later periods, influence the amount of loosing of waving of mosquito liquid, thereby cause the instability of drug effect.
[summary of the invention]
Deficiency at above-mentioned prior art exists the purpose of this invention is to provide a kind of mosquito liquid that mosquito is used of killing with formedness price ratio.
Second purpose of the present invention provides a kind of preparation method of above-mentioned mosquito liquid.
In order to realize the object of the invention, the present invention is achieved by the following technical solutions: mosquito liquid, comprise mosquito liquid and volatilization core, described mosquito liquid comprises following parts by weight component: as chlorine fluorine ether chrysanthemum ester 0.2～2, the stabilizing agent 1～10 of active ingredient, wave to loose and adjust agent 2～20, organic solvent 67～96 and a little auxiliary.
Described chlorine fluorine ether chrysanthemum ester is the former medicine of pyrethroid, and its chemical structural formula is as follows:
Described stabilizing agent is selected from a kind of in antioxidant 2,6 di tert butyl 4 methyl phenol, ditert-butylhydro quinone, butylated hydroxyarisol, 3 (3.5-di-t-butyl hydroxy phenyl) the propionic acid octadecyl ester.
Described waving loose to be adjusted agent and is selected from one or both and two or more combinations in isopropyl myristate, dibutyl phthalate, the isopropyl palmitate.
Described organic solvent is selected tasteless kerosene for use.
Described mosquito liquid also comprises auxiliary agents such as essence or synergist.
Described volatilization core is the fiber plug.
The preparation method of mosquito liquid, may further comprise the steps: in the composition weight umber ratio in the above-mentioned mosquito liquid, successively with organic solvent, wave and loose to adjust agent, active ingredient chlorine fluorine ether chrysanthemum ester, stabilizing agent and auxiliary agent and when stirring, join in the stirred tank, the back filtration that stirs is canned, insert the volatilization core that is equipped with plunger then, promptly get described mosquito liquid.
Mosquito liquid of the present invention is as follows at the application method aspect the control mosquito: be preferably in relatively airtight place, space, with mosquito liquid and the supporting use of electric heater; Open switch, mosquito liquid is waved soup to shed by the effect of volatilization core and under the electric heater heating condition, is suspended in the air, after the active ingredient in space reaches finite concentration, just the mosquito generation is driven, is knocked down even lethal effect.
Compared with prior art, the present invention compares the advantage that is had with prior art and is: mosquito liquid of the present invention, on active ingredient, solvent, volatilization core, all done improvement, and cost performance of product is enhanced.Wherein, chlorine fluorine ether chrysanthemum ester with compare with the alkynes third chrysanthemum ester of amount, drug effect be its more than 5 times, and cost has only it below 1/3; With suitable substantially with the tetrafluoro methothrin drug effect of amount, but the price of chlorine fluorine ether chrysanthemum ester only is 1/3 of a tetrafluoro methothrin.Effect that described organic solvent tasteless kerosene can reach in mosquito liquid and tetradecane hydrocarbon (C14) basically identical commonly used, but its price only is 2/3 of C14, and freezing point is low, and low temperature environment is not-easy-to-freeze.Described volatilization core is the fiber plug, and product can not rupture in transportation and use, and is more anti-more disconnected than carbon dust plug, potter's clay plug commonly used; Volatilization process is difficult for stopping up, and it is more uniform and stable to volatilize; Moisture absorption is good, and making moist can not influence volatilization yet; Cost is low.In sum, the mosquito-proof effect of mosquito liquid of the present invention is better than the alkynes third chrysanthemum ester mosquito-repellent incense liquid, reach effect same with the tetrafluoro methothrin, but the consumption of the consumption of active ingredient and organic solvent has reduced all, reduced the mosquito liquid production cost of products, and reduced pollution environment.
