Abstract

  An insect control device is disclosed that includes a paper support that can burn slowly. The device according to the invention is characterized in that at least one insecticide is supplied.

Description

  The present invention relates to paper impregnated with an insecticidal active substance, a method for preparing it and its use for controlling insects.

  It is known that what is known, for example, as a vapor-producing tablet, can be used with the help of an electric heating device to kill or repel insects (eg mosquitoes) ing. In this method, a suitable material such as cardboard made of cellulose and cotton, asbestos, ceramic and / or porous resin is impregnated with a solution of the insecticidal active substance to form an insecticidal platelet. The insecticide is evaporated by the action of a heating device that produces a temperature of 120-190 ° C.

  A substantial disadvantage of the platelets that generate these vapors is that they do not release the active substance uniformly over the expected duration of action. When operating them, the release of active substances is usually unnecessarily high and then decreases continuously and rapidly. The activity of such steam generating platelets decreases during a given lifetime.

  For example, steam generators such as those described in GB-B-2 153 227 have also been known for household use. In such a steam generator, the solution is evaporated using an electrically heatable wick and the active substance is dissolved, for example, in a mixture of saturated aliphatic hydrocarbons.

  When using the product, the amount of organic solvent required in so-called liquid evaporators is large compared to the amount of active substance, but this large amount of organic solvent undesirably causes the concentration of the indoor solvent Becomes higher. As a result, among other things, the walls and objects near the device become dirty. This fact is often the subject of consumer claims.

  In order to keep unpleasant insects away, a battery-operated insecticide evaporator is known. In this battery-operated insecticide evaporator, the surface of the radiator slab is heated to 90-130 ° C. in order to evaporate the insecticide (DE 195 25 782 A1).

  Furthermore, DE 20 2004 008 226 U1 discloses a fuel product for controlling insects (especially for controlling insects when barbecuing), wherein the product comprises pores and And / or a support having a tear and a fuel comprising wax and / or paraffin and / or stearin, the fuel comprising citronella oil.

  It is also known to use an electrically operated fan to evaporate the insecticide, where the fan creates an air flow over a support impregnated with a solution of the insecticidal active substance. Such a fan system is described, for example, in WO-A-96 / 32843.

  EP-B-0 279 325 discloses natural substances and synthetic substances impregnated with transfluthrin (for example, insect papers, etc.).

DE 199 47 146 A1 discloses a support material impregnated with 0.05 to ² mg / cm ² of active substance selected from the series consisting of transfluthrin, pinaminforte, vaporthrin and praretrin. ing. The support material is used at room temperature to control wind insects in an enclosed space. As a result of the volatility of the insecticidal active substance, it is released from the support material, thereby ensuring a certain concentration of the insecticidal active substance in the air. However, the disadvantages of the systems described in DE 199 47 146 A1 are, firstly, that these systems have already released the insecticidal active substance by long-term storage, and that the system is at a later time. When used, it is unclear to the user how much activity the previously stored system actually shows. Secondly, the release of insecticidal active substances from the system is not efficient enough.

Furthermore, smoke coils that provide protection from small insects for 6-12 hours, for example, on the terrace, on the balcony, during camping, or indoors, such as Baygon® ) Coils are also known. To use, the ring is lit, but during the process the ring continues to generate heat, so that the active substance contained in the ring is released slowly and continuously in the open air or indoors. The In a room of about 20 m ² , one commercially available ring is required. However, the disadvantage of such rings is that they are fragile in use and therefore only a part of it is used.

  In addition, insect control aerosols or oil sprays are also used to rapidly remove insects from enclosed spaces. The space so treated can then be replaced with air if new insects can be prevented from coming. However, a disadvantage of such systems is that aerosol mist or oil spray mist is not well distributed into the room as a result of their size.

  All of the above products share the property that they are technically and inevitably complex and time consuming to manufacture and therefore expensive. Furthermore, the preparation of aerosols, oil sprays and spirals, which account for the majority of products worldwide, involves the production of a large amount of natural resources such as kerosene, propane / butane, wood meal adhesive, starch and Various formulation aids need to be used. In addition, their use usually requires that the associated packaging, such as tin containers, fans, plastic bottles, jackets, etc., be discarded at a later point in time.

GB-B-2 153 227 DE 195 25 782 A1 DE 20 2004 008 226 U1 WO-A-96 / 32843 EP-B-0 279 325 DE 199 47 146 A1 DE 43 223 76 A1 DE 196 24 819 A1 DE 100 22 989 A1

  In view of the above prior art, those skilled in the art are therefore faced with the problem of providing an insect control device that generally avoids the above disadvantages.

In a first embodiment , the solution to the above problem starts with an insect control device having a support that generates heat.

  Next, the support is supplied with at least one insecticidal active substance.

  Thus, according to the present invention, in a first embodiment, there is provided an insect control device comprising a support capable of generating heat and supplied with (for example by impregnation) at least one insecticidal active substance. Provided. In accordance with the present invention, the support is designed so that once it is lit, it will continue to emit heat after it has extinguished (eg, by blowing out or by a gust of wind) and will not completely extinguish. Has been. As a result of generating heat, the support releases at least one insecticidal active substance, thereby controlling insects.

Support
For the purposes of the present invention, the support is not subject to any restriction as long as it is capable of releasing at least one insecticidal active substance while generating heat.

  Suitable supports are, for example, cellulose based supports. An example that may be mentioned in this respect is a paper support, which is described in more detail below within the scope of the preferred embodiments. Further materials based on cellulose are, for example, wood chippings, wood chips or sawdust, rice husks, maize cob spindles (preferably without grain), pecan nuts Shells and peanut shells. In particular, a thin particle board is also suitable as a support material. Suitable supports based on cellulose are described, for example, in German patent application DE 43 223 76 A1. The disclosure of this patent application is incorporated herein by reference.

  Another possible support is based on fiber materials. Such supports may include, in part or in whole, synthetic fibers (eg, polyester or nylon synthetic fibers) or natural fibers (eg, cotton, viscol, linen / viscose mixture) or synthetic fibers and natural fibers. Mixtures of fibers (eg, cellulose polyester (synthetic paper) or cotton polyester) can be included. Another example is wool felt and Trevira satin.

  Another possible support is based on plastic materials capable of generating heat, such as polycarbonate, polyester, polyamide and polyterephthalate. Thus, a support component for an insecticidal active substance can be made from a plastic material in which the active substance is already incorporated before the support component enters the final manufacturing or molding process. It was included within the scope of the present invention. This active substance is within the scope of the invention that its activity is not adversely affected or only slightly adversely affected by the molding process of the support component, while the support generates heat. A distinction is made by the property that it can be released from its plastic support at an essentially constant evaporation rate. The method chosen for producing the support is in particular an injection molding process, in which an insecticidal active substance (eg pyrethroid) is mixed with a plastic starting material (eg polycarbonate) The resulting mixture is then processed in an injection mold to the final shape described. Examples of alternative manufacturing methods are extrusion or thermoforming.

  Within the scope of the present invention, it is particularly preferred to use a cellulose-based support.

  Within the scope of the present invention, it is furthermore very particularly preferred to use a paper support.

In a very particularly preferred embodiment , the solution to the above problem on which the present invention is based thus starts with an insect control device comprising a paper support capable of generating heat.

  The paper support is characterized in that at least one insecticidal active substance is supplied.

  Thus, according to the present invention, in this very particularly preferred embodiment, an insect control comprising a paper support capable of generating heat and supplied with (eg by impregnation) at least one insecticidal active substance. A device is provided. According to the present invention, once the paper support has been ignited, it will continue to emit heat after the fire has extinguished (eg, by blowing it out or by a gust of wind) so that it will not extinguish completely. Designed to. As a result of generating heat, the paper support releases at least one insecticidal active substance, thereby controlling insects.

  In a particular embodiment of this very particularly preferred embodiment of the invention, the device of the invention comprises the support (especially a paper support), the at least one insecticidal active substance, and, where appropriate, Consists of a further additive (for example potassium nitrate). Additional additives are described below.

Cellulose-based support-paper support According to the first embodiment, the apparatus of the present invention includes a paper support. The paper support contains cellulose. Cellulose is understood within the scope of the present invention to mean biomass derived from chemical digestion of plant fibers (most often wood) and consisting mainly of cellulose.

  Paper supports of the type according to the invention have been known for many years, but are not known in the field of insect control. Thus, for about 150 years, paper supports have been impregnated with the Asian tree resin “styrax”. The resulting product is referred to as “Armenian paper”. This “Armenian paper” is used to eliminate the odor of food or tobacco. French Auguste Pontet returned with the resin from his trip to Armenia. The resin is also used in the manufacture of fragrances and therefore reminds us of the odor of the fragrances. The paper is sold as a booklet with various numbers of papers. When using this paper, take a piece of paper out of the booklet and set it on in an ashtray, then turn off the fire and slowly generate heat. When the paper emits heat, it releases the desired fragrance, thereby ensuring a pleasant scent to the surroundings. The paper substrate according to the invention is used in a similar manner.

  In principle, the paper support used for this purpose is that the paper support is generally capable of absorbing at least one suitable insecticidal active substance and is ignited and extinguished. So, as long as the at least one insecticidal active substance can be liberated without substantially degrading, it is not subject to any particular restrictions.

However, the weight of the paper is preferably 25 to 300 g / m ² , in particular 25 to 270 g / m ² , particularly preferably 25 to 250 g / m ² , very particularly preferably 25 to 215 g / m ² , in particular 25 to 200 g. It has been found that a paper support of / m ² is particularly suitable for the purposes of the present invention.

  The thickness of the paper support is 0.1 to 0.5 mm, particularly preferably 0.15 to 0.45 mm, very particularly preferably 0.15 to 0.40 mm, and very particularly preferably 0.15 to 0 More preferably within the range of .34 mm, especially 0.15 to 0.32 mm.

  With regard to the dimensions of the individual paper supports, the present invention is not subject to any restrictions. However, the paper support according to the present invention can be used in a suitable manner by the user, i.e., for example, the paper support can generate heat in a specific container (e.g. an ashtray). It should be present in a cut form so that the paper support has such dimensions.

  The paper support, for example the paper support that can be used according to the invention, can take the form of, for example, a paperboard, for example an absorbent paperboard, cardboard or cardboard.

Insecticidal active substance In the device according to the invention, it is possible to use a support, in particular a paper support, supplied with only one type of insecticidal active substance. Alternatively, two or more kinds of insecticidal active substances, for example, two, three or four kinds of insecticidal active substances can be simultaneously supplied to the support, particularly the paper support.

  The selection of a suitable insecticidal active substance is, as a rule, essentially free from degradation of the insecticidal active substance at the exothermic temperature of the support (especially paper support) of about 350-600 ° C. The only limitation is that it is released into the surrounding air without essentially losing activity. Within the scope of the present invention, the term “without essentially decomposing” is 80% or less (preferably 70% or less, particularly preferably 60% or less, in particular 50% or less, in particular 40% or less).

  A suitable matrix material is that the at least one insecticidal active substance used according to the invention is released from the support material (eg a paper support) under normal environmental conditions (23 ° C., 1013 mbar). All systems that prevent

  Organic materials suitable as matrix materials include polyvinyl alcohol, wheat protein and derivatives thereof, carbohydrates, starch (from various plant sources), amylose and derivatives thereof, amylopectin and derivatives thereof, cellulose and derivatives thereof, hydrolyzed starch Modified starch, modified starch derivative, maltodextrin, hydroxypropylmethylcellulose (HPMC), polyvinylpyrrolidone (PVP), chitin, chitosan, polysaccharide gum and its derivatives, polyethylene glycol, polyester, hydroxyalkyl starch, polyvinylpyrrolidone / cellulose derivative, Casein, gelatin, solubilized protein s, polyacrylamide, polyamine, styrene / maleic anhydride resin, polyethyleneamine, xanthan gum and the like.

  Further examples that may be mentioned are polyacrylates, such as an optionally crosslinked maleinized or epoxidized polymer and an optionally crosslinked (meth) acrylate polymer. A condensate of a maleated or epoxidized polymer and a crosslinking agent (preferably a polyamine) is preferred. Examples of suitable polymers are polydienes such as polybutadiene, polydecadiene and the reaction product of soybean oil with a molecular weight of over 400 g / mol and maleic anhydride, and also copolymers of olefins (eg ethylene) and maleic anhydride Epoxidized polybutadiene is also an example of a suitable polymer. Preferred crosslinking agents are polyamines, in particular polyoxypropylene diamine and polyoxypropylene triamine. Other materials that are equally suitable as crosslinkers are triethylene glycol, polyethyleneimine and urea. The crosslinking reaction is preferably carried out in an alcohol solution (for example, in dipropylene glycol) at an elevated temperature. The maleic anhydride or epoxide groups or -NR-CO- groups and -CRH-O- groups of the crosslinked polymer (which are supplied by polyoxyalkylene polyamines) have a hydrophilic effect.

  Another type of cross-linked polymer is a monofunctional (meth) acrylate monomer (eg, hydroxyethyl acrylate or poly (propylene oxide) (ethylene oxide) monomethacrylate) and a multifunctional (meth) acrylate monomer (eg, ethylene glycol diacrylate). A copolymer of methacrylate or polyethylene glycol 400 dimethacrylate.The preparation of the crosslinked (meth) acrylate polymer is achieved by radical copolymerization of the monomers, in which case the crosslinked polymer absorbs liquids and gases. For example, it can absorb insecticidal active substances that are finely distributed in the liquid in dissolved or dispersed form.

  Another suitable matrix forming material is solid alkane carboxylic acids and gel-like metal salts of alkane carboxylic acids. Preferably, mention may be made of: stearic acid and alkali metal salts of stearic acid, such as sodium stearate, and also stearic acid and palmitic acid or mixtures of their alkali metal salts, such as sodium stearate A mixture of sodium palmitate.

5.2 Paper pre-processing Paper to be measured for pre-processing is cut to DIN A 4 size and clearly identified with the corresponding development number. The DIN A 4 paper sheet is accurately weighed (net weight).

Thereafter, 500 g of a 6% strength KNO ₃ aqueous solution is prepared. Care must be taken to use deionized water to prepare this solution. The final solution is identified by the corresponding development number and transferred to a V4A dish with a total volume of about 1 L. The paper is immersed in the 6% strength KNO ₃ aqueous solution. Care must be taken that the entire DIN A 4 paper sheet is immersed in the solution. After 20 minutes, the paper sheet is removed from the solution and compressed directly using a photographic roller press to squeeze excess liquid out of the paper.

  After compression, the paper sheet is dried in a drier (about 50 ° C.) until it reaches a constant weight, and again weighed accurately (total weight).

  The completed pretreated paper sheet is cut into specimen strips measuring 12 × 2 cm and properly identified.

5.3 Impregnation of the test strip Place a defined volume of the active substance solution on the test strip using an eppendorf type pipette. Care must be taken here that the total amount of active substance solution is evenly distributed over the surface of the analyte strip. The impregnated specimen strip is identified with an associated development number and hermetically sealed in aluminum foil. After an exposure time of as much as 24 hours, the subject strip can be removed from the aluminum foil for the relevant test. It is important to prepare a sufficient amount per analyte strip so that the intended test (eg, verification of biological activity and accompanying analysis, etc.) can be performed. A subject to be used at a later time is stored in a refrigerator.

5.4 The amount of Evaluation of KNO ₃ in an amount of KNO ₃ is carried out as follows:
· KNO ₃ in an amount / DIN A 4 sheet (total weight of the paper sheet) - (net weight of the paper sheet) = KNO ₃ in an amount · KNO ³ in gsm (g / ^{m 2)} Concentration (KNO per sheet 1 m ² ₃ Amount) / (area of DIN A 4 sheet) = KNO ₃ / m ²
