Description

Insecticide smoking paper

The present invention relates to a kind of improved insecticide smoking paper, introduced a kind of insecticide smoking paper that the Naked that is made up of effective ingredient, additive, inert carrier reveals superficial layer that on the paperboard that is adsorbed with combustion adjuvant, adheres to especially.Light this insecticide smoking paper, effective ingredient is very easy to evaporate from superficial layer.

Use mosquito-repellent incense that such problem is arranged: the effective ingredient of amount of calculation is to be dispersed in the long mosquito-repellent incense, the burning time of every mosquito-repellent incense is about 7 hours, effective ingredient is slowly fumigated out, can not make the very fast savings in space, place play enough effective ingredient concentration, therefore, the use mosquito-repellent incense is long to the time of knocking down of sanitary insect pest, the death rate is low, and not dead insect and offspring thereof also can produce drug resistance.This has just proposed a problem: need preparation a kind of in the short as far as possible time (a few minutes) effective ingredient of amount of calculation is fumigated out, is made the insecticide smoking product of the enough effective ingredient concentration of the very fast savings of the interior space from carrier.

7504 kill mosquito smoking papers by the military section's word of Hubei Province Q/W995-82 (1982)-No. 006 production can reach above-mentioned quick requirement, but because effective ingredient is to be evenly dispersed in the yellow plate paper and to burn to neglect slow unstability suddenly soon, effective ingredient be heated flee from paperboard before, have some destroy to be divided and take off by high temperature.Mosquitos and flies rod of " Liaoning chemical industry " the 3rd phase in 1987 the 9th page of description and the deinsectization cigarette paper of " the medical officer people " 1985 the 7th phases the 33rd page of description, though all belong to the smoked product of the quick-acting combustions of papery, all have effective constituent subjects to the decomposition of high temperature destruction when being heated volatilization owing to being obstructed layer by layer problem.Day, the disclosure was speciallyyed permit the insect preservative paper that clear 60-2799 proposes a kind of slow release fumigation type, and WO84/02447 proposes a kind of pesticide paper of killing the insect that creeps that contacts, and they are not the smoked product of combustion, neither be quick-acting, in application, all be restricted.

Mosquito-repellent incense (comprising the sterilization fragrant incense) and in the past the effective ingredient volatility that all mixes in the type deinsectization smoking paper of poor combustion stability have only about 60%, all the other are partly fallen by pyrolytic entirely.Effective ingredient in the smoked product of combustion accounts for exhausted major part in cost of material.How strengthening the effective ingredient volatility to reduce the effective ingredient use amount, can reach the desirable result of use (being evaporated completely effective ingredient in a few minutes) that plays a role fast and be suitable for suitability for industrialized production again, is to be worth research.

The present invention aim to provide a kind of very easy manufacturing, effective ingredient very easy quick-acting insecticide smoking paper that volatilizees from additional exposed surface layer when being heated, with the use amount that reduces effective ingredient, improve result of use.

The present invention is achieved in that with containing the paper (inert carrier of effective ingredient) that the adhesive of the promoter of volatilize will be thinner than paperboard and is attached on the paperboard two sides that is adsorbed with combustion adjuvant, and the method that is coated with dipping or brush or spray or roller is evenly distributed on the soup that effective ingredient, proper additive are dissolved in organic solvent on the paper that is attached to paperboard two surfaces.Also soup can be coated on earlier on the paper, the paper of using the adhesive that contains volatilization promoter, irritating smoke remover will be loaded with effective ingredient again sticks on the paperboard that is adsorbed with combustion adjuvant.Also the soup that contains pesticide can be coated on wherein on the superficial layer, and the soup that will contain bactericide is coated on another superficial layer.

Another realization approach of the present invention: effective ingredient, additive, adhesive, powder dispersing agent (inert carrier of effective ingredient) and water are deployed into slurry (available in case of necessity organic solvent is dissolved with effective constituent, additive earlier), and the method that is coated with brush or roller is evenly distributed on this slurry on the paperboard face that is adsorbed with combustion adjuvant.

No matter adopting which kind of method, all is to implement easily.The size of final products and shape can be appointed fixed.

Effective ingredient is meant and meets stifling high-efficient low toxicity insecticide (preferably Dalmatian chrysanthemum, pyrethroid, 2,2,2-three chloro-1-(3,4-dichlorophenyl) the ethyl acetate that requires of health and epidemic prevention, DDVP, the metrifonate in the organophosphor), bactericide (preferably acetate, lactic acid, bactericide), can singly use with a kind of pesticide or multiple pesticide, also can pesticide and bactericide all use.Additive is meant that synergist is (to Dalmatian chrysanthemum or pyrethroid, piperonyl butyl ether preferably, sesame oil), volatilization promoter (Celogen Az preferably, bicarbonate, the gas that their chance pyrolytics go out can be taken away effective ingredient), antioxidant (dibutyl hydroxy toluene preferably, butylated hydroxy anisole), irritating smoke remover (calcium carbonate preferably, carclazyte, they also can be used as the inert carrier of effective ingredient), essence (all sorts of flowers essence preferably, osmanthus flower fragrance, cream jasmin france), colouring agent (Viride Nitens preferably, Methylene Blue BB), can, also can use with one or more.Inert carrier is meant paper thinner than paperboard (preferably loose wadding or the filter paper of papery) or powder dispersing agent (preferably wood powder, carclazyte, china clay, calcium carbonate), as uses powder dispersing agent, can use with one or more.As for the selecting for use of effective ingredient, additive and the inert carrier of forming superficial layer, ratio, assembly order, coating program, the short of scope and spirit essence of the present invention of leaving defined in claims of the present invention can be done appropriate variation or replacement.Final products not only have killing action to indoor flight sanitary insect pest, and are also effective to the indoor sanitary insect pest of creeping.In the effective ingredient,, the interior space and body surface also had sterilization if any bactericide.

Most preferred embodiment of the present invention is as follows.

Example one: (the excellent Ke Fu of French Russell company produces with 3.28 gram esbiothrins, the allethrin of d-trans-chrysanthemate isomer comprises 72%), 128 gram lactic acid, 13 gram piperonyl butyl ethers, 1.4 gram dibutyl hydroxy toluenes and 3.28 gram cream jasmin frances are dissolved in 95% ethanol, get soup, stand-by.With the adhesive that contains 19.7 gram Celogen Azs, wadding is attached on the two sides of one one No. 10 yellow plate papers of opening that are adsorbed with combustion adjuvant, dry back is uniformly coated on above-mentioned soup on the two additional superficial layers of this paperboard with roller, evenly is cut into 256.Every contains 12.8 gram esbiothrins, is used for 35 cubic metres of confined spaces, is 3.2 minutes to the killing effect of Culex pipiens pallens: kT50, and the death rate 98% in 24 hours.This product is to annihilating other sanitary insect pest and air sterillization also being had good result.

Comparative example: as above-mentioned soup directly all is mixed in the yellow plate paper that has been adsorbed with combustion adjuvant, make every to contain esbiothrin and increase to 16 milligrams, (ratio one increases by 20%), and killing effect: kT50 is 3.5 minutes, the death rate 92% in 24 hours.

Example two: with 205 gram metrifonate, 64 grams 2,2,2-three chloro-1-(34-dichlorophenyls) behind ethyl acetate and the 224 gram calcium carbonate powder mixing, be added in the thickness aqueous solution of the sodium carboxymethylcellulose that contains 39.3 gram carbonic hydroammonium and an amount of Viride Nitens, high-speed stirred becomes starchiness, with roller it is uniformly coated on one one No. 10 yellow plate papers of opening that are adsorbed with combustion adjuvant, evenly is cut into 256 after the drying.The test method that use-case one is same, killing effect: kT50 is 6.8 minutes, the death rate was 100% in 24 hours.

Comparative example: as effective ingredient is increased by 20%, with combustion adjuvant all be mixed in the yellow plate paper with known method or on the paper slip again rewinding become round bar shape.Killing effect: kT50 is 7.5 minutes, and the death rate was 98% in 24 hours.

The present invention is owing to have the paperboard of combustion adjuvant to adhere to superficial layer in absorption, thereby improved the stability of burning, particularly since effective ingredient, additive all be distributed on the inertia exposed surface layer, so very volatile come out when effective ingredient is heated. So not only can bring into play fast drug effect (effective ingredient is evaporated completely) in a few minutes, and the more important thing is and to reduce significantly effective ingredient use amount (reducing 20% than known technology), improve result of use. The very easy enforcement of the present invention, suitability for industrialized production.
