Abstract
An insecticidal barrier made of an inanimate material comprises a first zone and a second zone. The first zone contains synergists, and the second zone contains insecticides but does not contain the synergists.
Description
The application be that on 06 29th, 2007, application number are 200780053561.6 the applying date, the application people divides an application for Disease Control Textiles SA, the invention and created name Chinese invention patent application that is " part is with the insecticidal barrier of synergist ".
Technical field
The present invention for example, about the insecticidal barrier of the non-living material that comprises pesticide and synergist, mosquito net.
Background technology
The different pesticidal processing of net and the different application of this net disclose in the prior art, for example the international application WO01/37662 of Si Kefuman (Skovmand) has disclosed the generality processing of net, the international application WO03/003827 of Bao Er (Bauer) and Si Kefuman (Skovmand) discloses the application as fences, the international application WO03/090532 of Fo Disen (Vestergaard Frandsen) discloses the application hidden as protectiveness, or the international application WO06/024304 of Fo Disen (Vestergaard Frandsen) discloses the application as the air cleaning net.
One of problem that mosquito net (mosquito nets) and pesticidal fabric suffer from appears in the test of field, and these tests are found can reduce when mosquito net is exposed to Exposure to Sunlight or extensively touches the heat aging fruit.In order to keep long-term lasting effect; the international application WO 03/063587 of Fo Disen (Vestergaard Frandsen) is proposed in fibre structure and is incorporated to pesticide; to make pesticide move to gradually fiber surface, wherein this pesticide is to combine with ultraviolet protective agent.
In order to promote the effect with general basis, someone proposes should comprise synergist in fabric and net.For instance, at the U.S. patent application case US 2007/0009563 of Hai Tebi Supreme Being Soviet Union (Hataipitisuk) and not in the people's such as Buddhist nun (Mooney) international application WO 90/14006, PBO is proposed as the effect promoting agent in pesticidal fiber and fabric.The people's such as the people's such as Ke Luoding (Koradin) international application WO06/128867 and Ka Er (Karl) international application WO06/128870 propose PBO as fabric and net in synergist.
In general, insect metabolism pesticide is day by day serious problem, and someone proposes piperonyl butoxide (Piperonyl Butoxide) (PBO) for resisting the resistance to the action of a drug.Spray afield the prescription face, PBO is that to reduce the resistance to the action of a drug famous, is for example given institute in the British Patent Application case 2 388 778 of Luo Shashite (Rothamsted) and discloses.The people's such as mountain gloomy (Samson) United States Patent (USP) 5 503 918 discloses amylopectin (amylopectin) as the pesticidal synergist in tent fabric, and she US 3 859 121 that steps on people such as (Yeadon) is disclosed in packing and uses PBO as synergist.
Yet concertedness chemicals expensive, increase treated fabric or the cost of net, this is unfortunate in many situations, particularly when net or fabric must be in the area of low income for seasonable.Therefore, provide on the one hand the net or the fabric that reduce the resistance to the action of a drug and effect enhancement characteristic, reducing costs on the other hand is that we want.
Summary of the invention
Therefore the purpose of this invention is to provide a kind of insecticidal barrier, it has the insecticide resistance resistance to the action of a drug and promotes the device of pesticidal effect, but minimizes the cost of this device.
This purpose is to realize with the insecticidal barrier of non-living material (being mainly net or fabric), and it comprises the firstth district and Second Region, and wherein this firstth district comprises that synergist and this Second Region comprise pesticide but containing synergist.
Due to this barrier (for example mosquito net) only have the part with synergist, its cost lower than whole barrier with synergist.Thus, the area of imagining this firstth district is the order of magnitude at Second Region, or is preferably and is less than Second Region, for example is less than in fact Second Region.Term " in ... grade " should be appreciated that Second Region is the most much 50% compared to the firstth district, is preferably compared to the first district the most much 20%.The area that term " is less than in fact " expectation the firstth district is to be less than 50% of Second Region area, be preferably be less than the Second Region area 25% or even be less than 10%.Although the area in the firstth district is less than the area of Second Region, be less than even in fact Second Region, synergist may be very effective, will illustrate in greater detail below.
Trial can contact several parts of barrier while passing through the passage of barrier military order flying insect (particularly mosquito) in finding barrier.For that reason, insect may touch first and also have Second Region very much, thereby accept synergist, also has pesticide, although in fact this synergist exists only in barrier partly.
Term " barrier " should be by the broad sense identification, and it also comprises pesticidal catcher (trap).For instance, term " barrier " also comprises wall linen, and insect can have a rest thereon, but insect there is no the intention of passing through it.
Term " synergist " comprises a kind of synergist or multiple synergist, wherein multiple synergist may but mixture not necessarily.The first synergist that the firstth district may be included in part the firstth district reaches another synergist or other synergists in other parts of the firstth district.Term " synergist " also comprises analog or the predecessor of synergist.Term " pesticide " comprises a kind of pesticide or multiple pesticide, wherein multiple pesticide may but mixture not necessarily.Second Region, or first and two districts of another selection, first pesticide that may be included in the part Second Region reaches another pesticide or other pesticides in other parts of Second Region.
In a further embodiment, the firstth district is the upper section of barrier and the below part that Second Region is barrier.Many mosquito nets are provided with obvious roof and obvious side wall, on roof, provide synergist and side wall that pesticide is provided but do not provide synergist to have benefit.This benefit is many-sided.At first, have been found that they typically are parked on the roof of mosquito net when mosquito maiden attempt passes through barrier.Under this situation, synergist is transferred to mosquito.In continuing the process of attempting, mosquito down finds passage and absorbs pesticide.This absorbs with respect to synergist and absorbs through delaying, and increases effect because synergist destroys the resistance to the action of a drug gradually.The area of the roof parts that second benefit is mosquito net is much smaller than the side wall area.Therefore, the net of less area must comprise synergist, and this price that means net can not increase than the pesticidal net of standard too many.Consider that above-mentioned mosquito typically first is parked in the fact on the roof of net, this mosquito net resist drug-fast characteristic not can than whole throw the net for example, through destroying the weak effect that drug-fast synergist (PBO) processed too many.
Because synergist is promoted the effect of pesticide, so the pesticide consumption on the Second Region of barrier can be reduced, and so can reduce the holistic cost of barrier, and simultaneous minimization is released into the desinsection dosage in environment.In general, for example the cost of synthetic pyrethrosin is quite expensive for pesticide.Therefore, normally we want for the amount that minimizes pesticide, reduce the impact on environment simultaneously.Take in the embodiment that mosquito net is barrier of the present invention, reducing the extra charge that pesticide on side wall especially can the balance synergist causes, because the area of side wall is greater than the area of roof parts.
The firstth district of barrier may comprise one or more synergist and one or more pesticide.In the case, synergist all is transferred to insect when contacting with pesticide, and this means that pesticidal effect and resistance to the action of a drug destruction get started.If barrier is the above-mentioned mosquito net with roof and side wall type, pesticidal effect will be brought into play in the roof of this net when mosquito contacts for the first time.This embodiment also has advantages of that roof and side wall all can be used prefabricated pesticidal net materials, wherein except among roof Material or on pesticide, this roof is processed through synergist.For instance, the pesticidal net of standard can be used as basic material, and roof parts is processed through synergist as part of the present invention.
Perhaps, the firstth district may comprise synergist but not contain pesticide.This measure reduces the expense of pesticide, because the firstth district does not need this class chemicals.In the case of mosquito net embodiment, the roof parts of net and wall can be through different disposal.For instance, roof parts can or make pesticide and in the material of this net through impregnated with insecticides through synergist dipping and side wall.Being incorporated to pesticide is to be described in the international application WO 03/063587 of Fo Disen (Vestergaard Frandsen).
The firstth district of barrier can be provided by polymer substrate, wherein synergist is merged in to move to gradually stromal surface from matrix inside, or another selection is, the firstth district is provided by polymer substrate, wherein synergist is to enter the certain depth under stromal surface through dipping, with this matrix inside certainly, moves to gradually material surface.Thus, can reach long-term lasting effect.During synergist can be integrated into material the melting phase in production process for example, wherein extruding is a kind of possibility.For instance, synergist is and passes through and flood or be merged in together with pesticide together with pesticide or.
One preferably composition be incorporated to synergist (for example PBO) in host material but in this matrix not containing the polymer substrate in the firstth district of pesticide, and for example comprise the go out peaceful (deltamethrin) with pesticidal coating at least part of surface of this polymer substrate.Thus, in fact this matrix in the early stage state with containing pesticide but comprise synergist.Therefore, in other embodiments, the matrix of this non-living material is at least not containing pesticide before the coating processing.Although state is not containing the pesticide be incorporated in the early stage for matrix, this pesticide can move in polymer substrate from coating after ensuing coating step, and this is still in scope of the present invention.Therefore, in other embodiments, when matrix be the initial stage, during not containing the solid state of pesticide, it comprises at least one synergist, wherein when its be finally, during solid state, it comprises pesticidal coating.In order to make PBO arrive the surface in the firstth district, this film can make synergist move through this film.
Synergist by being incorporated to the ability with the stromal surface of moving to, to polymer substrate, can provide the product of multiple final pesticidal constituent for you to choose, and wherein the matrix in the firstth district is through coating.
Perhaps, synergist can be imparted to the surface in the firstth district, for example, by membrane coat, surface printing or initiatively printing.
For instance, the firstth district and/or Second Region can apply in WO 01/37662 the washable polymer film disclosed.In this example, this film comprises the film forming component, it reaches selectively anti-oil film by the formation water resistant and is washed off and degrade with the pesticide reduced in this net or fabric, this film is on matrix or the screen of molecule on every side, it integrates pesticide in film, and wherein the film forming component comprises the key fixative of aggretion type and one or more composition that is selected from paraffin oil or wax, silicon, silicone oil or wax and gathers fluorine carbon or derivatives thereof.Preferably, this film forming component comprises the poly-fluorine carbon side chain be connected with the key fixative of aggretion type.Preferably, this pesticide is to be fixed on movably between these poly-fluorine carbon side chains and the waterproof by the hydrophobic effect of poly-fluorine carbon.This expression pesticide can be prevented lip-deep water or oil, as long as pesticide is to be positioned among the poly-fluorine carbon of protectiveness.Thus, importantly pesticide is fixed between side chain releasedly.In other words, pesticide should have mobility, so just can break away from the backbone, move to the film surface to be absorbed by insect.This moves to small part and is subject to the insecticide concentration gradient and controls, but also can provide initiatively mobile promoter or inhibitor to find out best translational speed, makes the pesticide of enough high doses can be positioned at for a long time the superficies of fiber.
In addition, synergist for example PBO is movably fixed too between side chain, to prevent from being washed off but still can move to gradually the film surface to be absorbed by insect.This is advantage of the present invention.Yet, the method that WO 01/37662 discloses and coating, for example the go out and rather with PBO replacement pesticide, there is generality with the composition of pesticide and synergist, may also can be more widely used and not necessarily will comprise PBO in the firstth district and Second Region comprises pesticide.
If want to have not containing pesticide but contain for example film formation composition of PBO of synergist, the method disclosed in WO 01/37662 can be used to provide the coating that contains synergist, to replace the pesticide in coating.This is an advantage for the purpose of the present invention but has generality, may also can be more widely used and not necessarily will comprise PBO in the firstth district and Second Region comprises pesticide.
In addition, the method that comprises pesticide and/or synergist that WO 01/37662 discloses can be modified, if
I), in the solvent that pesticide and/or synergist are dissolved in alcohol or ethylene glycol are combined, the water content of this alcohol or ethylene glycol is lower than 5%, or
Ii) pesticide and/or synergist are dissolved in solvent and mix with water or mix with water emulsion or the solution of temperature lower than 30 ℃, and this solvent selectively combines with alcohol or ethylene glycol before mixing, or i) and combination ii).This improvement is because of two aspect i) and ii) all reduce the risk that pesticide precipitates in combination solution.This reduces the valid expiration date of the pesticidal activity that extends film and promotes fastness to washing.This is particularly suitable to pyrethrosin, and wherein preferably pesticide is the go out peaceful or Permethrin (permethrin).Therefore adopt step I) or adopt step I i) compared to prior art, be the improvement thing, yet best improvement thing is by being used i) with composition ii), reach.
The film forming component can comprise other compositions such as the UV protective agent, preservative agent, cleaning agent, filler, shock-resistant modification agent, antifog agent, blowing agent, fining agent, nucleator, coupling agent, prevent the conduction promoting agent of static, stabilizing agent is such as antioxidant, carbon and oxygen radical agent for capturing and peroxide dissociate agent and this analog, stagnant flame agent, releasing agent, brightener, spreading agent, anti-caking agent, anti-mobile agent, mobile promoter, the formation of foam agent, anti-fouling agent, anticorrisive agent, thickener, other are except biological agent, wetting agent, plasticizing sticker or antitack agent, spices, other liquid of pigment and dye well comprise water or organic solvent.
It is to be disclosed in the people's such as Liu (Liu) WO 2006/092094 that another kind is applicable to pesticidal coating of the present invention, and it is about a kind of net/fabric coating that comprises pesticide, moisture sticker (as aqueous polyurethane latex or polyacrylate latex) and crosslinking agent (as the epoxy polymer crosslinking agent).Some also can be used for different concoction of the present invention is to be disclosed in WO 2006/092094, more particularly, its disclose a kind of for drive and kill mosquitoes/insect complete liquid, its formula (according to mass percent) comprises:

Preferably, pesticide of the present invention is pyrethrosin, be preferably the go out peaceful or Permethrin, but other pyrethrosins is also applicable, as the list disclosed in WO 01/37662.Yet the present invention is also about amido formate (carbamates) or the organophosphor of constituent for dipping.The list of possibility pesticide is see in WO 01/37662 or also comprise in the WO 06/128870 of pest repellant embodiment widely.
In addition, term " pesticide " also is applicable to as the present invention and above description for the insecticides in the constituent of dipping.For instance, pyrethrosin can combine with amido formate or organophosphor, to kill the insect with resistance simultaneously.Same, two or multiple pesticide can be applied on the different piece of net or fabric, for example, by printing or spray application, and, without mixing and being used in heterogeneity, this measure has benefit on toxicology and registration reason.When net is used on a large scale, substituting or complementarity pesticide also can be the pesticide with sterilisation-effect, makes the mosquito sterilization can't produce follow-on mosquito.This insecticides can have benzoyl urea group or triazine.
Other possible compositions comprise in WO 06/127407 that the U.S. fluorine disclosed combines the 1-Phenyltriazole disclosed in the N-virtue hydrazine that discloses in (metaflumizone), WO06128870 or WO06128867 and for example combine with pyrethrosin.
In addition or another be chosen as, pesticide can combine with synergist in coating, Butacide (piperonyl butoxide) for example, sulfoxide (sulfoxide), Piprotal (tropital), Bucarpolate (bucarpolate), Ethodan (ethion), cloth flies pine (profenofos), or the pine (dimethoate) of going out greatly, CPR dust (piperonyl cyclonene), TPP, diethyl maleate (Di-ethyl maleate), NIA-16388(NIA), S-421, MGK-264(double-heptene dicarboximide (bicycloheptenedicarboximide)), S, S, S-tributyl carbophenothion acid esters (S, S, S-tributyl phosphorotrithioate(DEF)), N-octyl group double-heptene dicarboximide (N-octylbicycloheptene dicarboxaminde), sesamin (sesamin), sesamolin (sesamolin) or Safroxan (sesamex).
Other substitutes for coating of the present invention are to be disclosed in US2007009563, wherein the solution formula according to various embodiments of the present invention comprises following 4 parts: 1. from the pesticide of pyrethrosin group, peaceful such as the go out peaceful, benefitization sharp (esfenvalerate), ether chrysanthemum ester (ethofenprox), Bi Fenning (biphenthrin), Permethrin and celo, it has quick activity and higher boiling.2. line stabilization promoting agent, for example compound of perfluorinated acrylate, resin, viscose glue and polyacrylate.3. thickener such as starch, glue and titanium dioxide.4. solvent, for example water.
As mentioned above, except the firstth district, Second Region also can provide pesticide in membrane coat.Therefore, at first the firstth district establishes with synergist, and the firstth district and Second Region are through pesticidal membrane coat afterwards.
Term " coating " comprises the surface treatment of using mutually and become solid with liquid or gas.As substitute or the additive of membrane coat, first and/or the synergist of Second Region is processed and/or the pesticide surface treatment can be reached by the material that printing comprises synergist and/or pesticide on barrier.Printing can cause providing material or powder ball on the surface of barrier or by making pesticidal material enter the active printing in the material of fiber.Other provide synergist and/or pesticide to the method on barrier surface is by the lamination in first and/or two districts.In addition, synergist and/or pesticide can provide by the composition of above-mentioned technology.
If the surface treatment containing pesticide is to provide on the firstth district with synergist, and the most of of the firstth district contained in this surface treatment or all, this surface treatment must be able to make synergist move to the barrier surface.For example, yet, if this surface treatment is the part that is applied to the firstth district, by printing point or striped, this surface treatment need not make synergist move.This expression does not only provide the surface-treated zone at those, and synergist is transferred to it insect.
Other medicaments for example insect chemosterilant or medicament with entomopathogen also can be applied to resist the insect relevant with the present invention.For instance, these medicaments may be applied to the barrier surface.The example of the fungal organism insects agent of antagonism insect is to be described in Nature Reviews Microbiology by Rob Thomas (Thomas) and Li De (Read), Vol.5, and May 2007, p.377.Although current, as if particularly the fungi entomopathogen is the most effective, another selection or in addition, insect infection virus, bacterium or protozoon also can be used.
By using printing technology, not only pesticide and synergist can be applied to these zones of wanting to be used, and above-mentioned entomopathogen and/or insect chemosterilant also can be employed.Spray or printing technology by use, point or the large block of exact position and exact dose can be provided.In addition, different medicaments can only not placed side by side also can be over each other, the removable cover layer that passes through of different medicaments.
In one embodiment, the firstth district of net comprises synergist, and Second Region comprises pesticide ， 3rd district and comprises entomopathogen Ji 4th district and comprise chemosterilant.Perhaps, only use three kinds in these medicaments.
Another is chosen as, and Second Region is to be provided by polymer substrate, and wherein one or more pesticide is merged in or floods to move to gradually material surface from material internal, to possess the long-term pesticidal effect continued.Flood and be incorporated to pesticide and explained in more detail in the international application WO 03/063587 of Fo Disen (Vestergaard Frandsen).
As other replacement scheme, Second Region can be provided with to be merged in or to flood the first pesticide entered in this polymer substrate also has pesticidal film.Pesticide in matrix may be different from the pesticide in film, and this can be taken as the pesticidal drug-fast alternate manner of a kind of pesticide of antagonism.
About the mobile aspect of synergist and/or pesticide in the firstth district, importantly consider synergist and/or the pesticide translational speed in matrix and the translational speed of other synergists or pesticide.For instance, mobile promoter that can be by suitably selecting selectively acting and mobile inhibitor are to regulate.
Barrier of the present invention can be provided as the different embodiment of structure.For instance, barrier can be net, fabric, film or oiled canvas or those composition.In other embodiment, the firstth district of barrier is that the barrier type by paper tinsel, oiled canvas, fabric or net provides, and Second Region is that barrier type by the barrier type that is different from the firstth district provides, for example paper tinsel, oiled canvas, fabric or net.For instance, the firstth district is provided by net, and Second Region is to be provided by oiled canvas or film.This kind of combination is used as the fences as disclosed in WO03/003827, and wherein this below part enters the net of open space for the insect that prevents from flying at low altitude, and wherein this upper section is the oiled canvas material, and it stops the insect upwards flown along net.This net provides the synergist that destroys insect resistance, and the time that the oiled canvas of top stops is enough long, is enough to make insect to be killed by pesticide after the resistance to the action of a drug is destroyed and before arriving open space.
Term " fabric " " contain braiding or knit goods or non-woven, also comprise Leah (Dumuria) fabric that rubs of shutting out, its braided fabric that is special quality.On the market, Du's Leah fabric that rubs is with PermaNet
the rub trade mark of Leah of Du provides.PermaNet
du's Leah fabric that rubs is effective insect barrier, especially more prevalent in the country area, because it has multiple variation and cheap.Preferably textile material is polyolefin (polyolefin), particularly polyester (PET (PET)) or polyethylene.As mentioned above, synergist and/or pesticide can be integrated in material or be provided as coating.As for the fabric of non-woven, the present invention is specially adapted to the blanket class.The one side that this blanket can be provided with the one side that comprises synergist and comprise pesticide.Therefore, the face contacted with human body can comprise health is threatened to low-down pyrethrosin, but another side comprises the synergist that usually should avoid the popularity skin contact.The purposes of non-woven blanket class is to be described in international application WO 03/090532.
Zones of different also can be sewn to together, for example spells the cloth shape.Another better purposes of the present invention is for wall linen (wall-linen), its fabric for hanging by wall, and purpose is to shift pesticide and synergist to it the insect had a rest on wall linen.
In application facet, when this barrier is when net, for example circular or the mosquito net of square canopy form or the insect net of fences form, the mesh size of this net can prevent that the targeted insect through selecting from passing through this net, but other insects may can be passed through mesh.Mesh size is depending on purpose.Yet the barrier that makes barrier become the insect of all kinds is possible, for example, by using oiled canvas, fabric or film.Pesticidal oiled canvas is to be disclosed in the WO03/063587 of Fo Disen and Si Kefuman (Skovmand).
The another kind of method that reduces the consumption of necessary synergist can be reached by barrier mosaic master drawing case is provided, and the firstth district that wherein comprises synergist (can select synergist to mix with pesticide) is comprising pesticide but do not containing between the Second Region of synergist.For instance, this pattern can be parallel or vertical stripes, and it contains alternately synergist and the pesticide of content.When this barrier is mosquito net, the mosquito of attempting entering the space of backbarrier will contact several striped and be exposed to pesticide and synergist under the two.Provide synergist because this net only has part, do not improve even the synergist of ad-hoc location can maintain the high concentration cost, because be not that whole throwing the net all must comprise for example PBO of synergist.Other forms of pattern is feasible, for example the grid pattern of similar chessboard.In this example, the gross area in the firstth district is less than the area of (may be less than in fact) Second Region equally.
The application technique that possible synergist and/or pesticide are used comprises printing technology and spray application.For example, synergist and/or pesticide can be printed on mutually top of each other.
The application of net of the present invention be extraly about as aforementioned international application WO 01/37662 in the protectiveness that discloses in the fences, international application WO 03/090532 that disclose in the net, international application WO 03/003827 that the disclose air cleaning net that hides, disclose in international application WO06/024304 or as being incorporated in fibre structure to move to gradually fiber surface of announcement in the international application WO 03/063587 of Fo Disen.Therefore these announcements are to include in herein with reference pattern.
When the present invention is used for fences, if can use double-deck fences structure that the height vermins-proof effect need to be provided, for example for to protect mankind, be not subject to attack of insect.This double-deck fences structure comprises with shielded open space has the first fences of a segment distance to reach the second fences around to the small part open space.The first fences is to provide synergist and selectable pesticide.The second fences is to provide pesticide.Low flight insect in approaching will first contact the first fences and absorb synergist, PBO for example, it destroys insecticide resistance gradually, makes to delay contact second fences and have a high proportion of pesticidal shooting down, and so insect does not have the time enough attacks after absorbing synergist.If the first fences also provides pesticide, can expect the highest death rate is arranged.This pesticide is optionally different from the pesticide of second fences.
Preferred embodiment is about having as the roof in the firstth district and the tester that comprises synergist, and this tester has as Second Region and the side wall that comprises pesticide, and wherein this side wall is to be provided by the protectiveness train of dress at the side wall lower edge.The material of this train of dress is preferably paper tinsel, fabric or oiled canvas.
Other application of principle of the present invention be the mesh size about pesticidal firstth district of top can prevent insect through selecting for example mosquito pass through the insecticidal barrier of this barrier.Second Region is for extending upwardly to the below part of the height more than 40 centimeters from this barrier lower edge, for example, be 60 centimeters or 80 centimeters away from lower edge more than.In another embodiment, the below part of this barrier only extends upwardly to the height of 80 centimeters or 100 centimeters.For instance, Second Region may extend upwardly between 60 to 80 centimeters or between the height of 80 to 100 centimeters, goodly is about 90 centimeters.
For instance, lower zone may have upper section and below part, this upper section be net and this below part comprise pesticidal fabric, pesticidal oiled canvas, net materials tearing strength higher than the pesticidal net of the net of upper section or those composition.By provide fabric, oiled canvas, paper tinsel or tearing strength higher than the net materials of the net of upper section to the below part, can reduce the risk of tearing this barrier, because the below part especially easily is exposed among mechanical wear.
In addition, with regard to mosquito net, when the firstth district is that to make the simultaneously upper section of lower zone by net be net, fabric, oiled canvas or paper tinsel, below partly prevents that sand fly from jumping into the space under barrier.Sand fly is normally dangerous, because biting of they can cause leishmaniasis (Leishmaniasis).The mosquito net of prior art can't prevent that sand fly from entering in net, because they can pass through the mesh of this net.Yet, because sand fly is jumped to such an extent that be not very high, the present invention also has advantages of that the sand fly of preventing bites, even this barrier is as Usage of bednets.
The below part of insecticidal barrier can extend downward floor or extend to fabric train of dress, oiled canvas train of dress or paper tinsel train of dress, and wherein train of dress extends upwardly to certain height, for example 10 centimeters or 25 centimeters.This train of dress itself is common in circular or square canopy sample barrier, is commonly used to as tester.
One preferably solution be the mosquito net type barrier of tester or other kinds, it has the roof parts as the firstth district that comprises synergist (selectable and insecticide composition), and as comprising pesticide but not containing the side wall of the Second Region of synergist, and the train of dress of for example, being made higher than the net materials (thering is thicker line and less mesh size) of the net of upper section by fabric, oiled canvas, paper tinsel or tearing strength.
Another preferred embodiment is not necessarily to want cleithral insecticidal barrier, the upper section that wherein this firstth district comprises this barrier, the below part that for example upper section of side wall, and this Second Region comprises this barrier, for example the below part of side wall.For instance, this below part extends upwardly to be 60 centimeters away from lower edge more than, selectable upwards to from 80 centimeters of lower edges or 100 centimeters.In addition, this barrier comprises the train of dress that extends to certain height, for example, from 10 centimeters of this barrier lower edges or 25 centimeters.With regard to the part of below, preferably, the tearing strength that this Second Region comprises pesticidal fabric, pesticidal oiled canvas, net materials is higher than the pesticidal net of the net of upper section or those composition.For instance, higher tearing strength can be reached by using strongr net materials.
In the advantageous embodiment of tool, the below part of Second Region may have higher screen frequency, higher yarn density and/or higher weight density.Net with higher screen frequency and/or yarn density also can complete in single production process, and wherein the weaving method of below part is different, for example, by comprising extra line.
In a feasible embodiment, the polymer substrate in the firstth district is that the thermoplastic polymer of extruding through melting by the squash type nozzle forms.The method can be provided for the fiber of net and fabric.Synergist can be added in the polymer of melting via the pipeline before the polymer transport screw rod, perhaps, contact the very of short duration time if only want to allow between thermopolymer and pesticide/synergist, just in the extrusion nozzle upstream or even add in extrusion nozzle.In particular composition, this may be critical, if particularly matrix is to make (PET (PET)) by polyester, it is preferably fabric and net materials.This is because the melt temperature of polyester is about 250 ℃, can cause synergist or pesticidal substance decomposition.
Yet the decomposition of synergist or pesticide and physical loss degree are not only determined by temperature, simultaneously also relevant with this medicament exposure time at high temperature.By minimizing the time of contact of medicament and high temperature, but significantly reduce loss.Here so-called loss comprises evaporation and possible thermal decomposition.
Therefore, in order to minimize the open-assembly time under high temperature, invented a special squash type nozzle principle.This principle is that nozzle has and can in extrusion, add synergist to the passage in molten polymer, and wherein this passage is the short distance upstream that is arranged at jet expansion.In this article, term " short distance " should be appreciated that the temperature that causes synergist or pesticide increases and time of passing through at this temperature still makes this retain enough complete synergists or the distance of pesticide in extruding matrix.For instance, can select to cause the temperature of synergist or pesticide to increase the maximized distance of time that maximization and synergist or pesticide are exposed to this temperature increase, wherein this maximized temperature and this maximized the limited time are in the predefined upper limit.
Amount that should " enough " is to determine according to synergist and/or pesticide and the acceptable extent of damage.In specific cases, it can be acceptable losing 99%, if 1% residual synergist and/or pesticide are still in the long-term scope to the drug-fast effective dose of insecticide resistance.In other cases, the loss ratio lower than 90% may be able to be accepted.Therefore, the invention provides a kind of synergist and/or pesticide of being incorporated to the method in thermoplastic polymer, although in fact the melt temperature of this polymer is far above the decomposition temperature of boiling temperature and/or this pesticide of this synergist.In the middle of experiment, be surprised to find that with regard to polyester, although extrusion temperature surpasses 250 ℃, it is complete that the synergist over 50% keeps.
In preferred embodiment, passage is to be arranged at the side of extruding, for example from jet expansion number millimeter or centimeter within.This means that at first it be subject to the impact of polymer temperature when the medicament that contains synergist and/or pesticide enters nozzle.For instance, nozzle may by annular pharmaceutical supply conduit around, it is in fact along whole edge injection medicament of the stream of the polymer liquid by nozzle to the polymer through melting.
This also allows medicament likely cooling before injection, so that this medicament is because absorb from the sclerosis of accelerating polymer and cooling of rising of the temperature due to the heat of polymer.In addition, the polymer through extruding can be in extrusion nozzle short distance downstream by active cooling, for example, by the cold wind air-flow.
Although by synergist and/or pesticide and in polyester, above-mentioned possibility is arranged, polyethylene far away lower melt temperature to make synergist and/or pesticide be integrated in polymer substrate much easier.Therefore, in order to utilize this fact, barrier of the present invention can be provided by multiple polymer, and for example the first polymer is used for Second Region for the firstth district and the second different polymer.
When barrier is day levelling mosquito net, this roof parts can be made and this side wall is made by polyester by polyethylene.Therefore under the relatively low melt temperature of polymer by synergist for example PBO to be incorporated to roof parts be relatively easy.Harder and uncomfortable polyethylene roof parts is seldom touched by the user, and the side wall of net can be made by the polyester of comfortable, softness and cotton sample sense of touch.
