Technical Field
The invention relates to a slow-release insect prevention/attraction material, in particular to an insect prevention/attraction material capable of releasing an insect prevention/attraction agent at a slow preset speed, which can achieve the effect of preventing mosquitoes, flies or insects for a long time by slowly releasing the insect prevention/attraction agent, wherein the insect prevention/attraction agent is divided into an insect prevention effect or an insect attraction effect according to the using mode.
Background
In addition to the distressing hot climates, mosquitoes and flies are also indistinguishable in hot summer.
Mosquitoes are the transmission medium for many diseases, and they can transmit diseases from one host to another by sucking blood, and arboviruses such as dengue fever, malaria, yellow fever, zika virus, filariasis, japanese encephalitis, west nile virus, chikungunya virus, etc. can be rapidly transmitted by this means. Flies often forage between human food and dirt, and therefore become the murder of spreading bacteria and epidemic infectious disease sources.
The common mosquito or fly prevention methods are environmental cleaning and insecticide spraying. However, people often do a lot of outdoor activities in summer, so that the mosquito bite cannot be avoided.
Although the mosquito-proof liquid can be sprayed on the body before outdoor activities, the mosquito-proof liquid has short time effect, so the spraying is required to be repeated. And the mosquito-proof liquid can be diluted by sweat, so that the mosquito-proof effect is reduced. Therefore, the development of a long-acting mosquito-proof article is urgently needed.

The average particle diameter distribution of the particles is 0.05-30 μm; the pore volume is 0.001-0.2 cm3(ii)/g; the diameter of the fine hole isThe water content is 1-35 wt%; the true specific gravity is 1-7; the volume specific gravity is 0.05-5; the specific surface area is 50-500 m2/g。
For example, in one embodiment, the slow release carrier can be a porous sodium aluminosilicate salt. If the slow release carrier is liquid, the conductive amount is 15-18 μ s/cm, preferably 15.5, 15.9, 16.3, 16.7, 16.9, 17, 17.1, 17.5 μ s/cm. If the sustained-release carrier is a microparticle, the average value of the diameters of the microparticles is distributed4 to 6 μm, preferably 4.1, 4.3, 4.6, 4.7, 5.1, 5.3 μm. The median distribution of the particle diameters is 4 to 6 μm, preferably 4.1, 4.3, 4.6, 4.7, 5.1, 5.3 μm. The pore volume is 0.008-0.02 cm3Per g, preferably 0.01, 0.012, 0.014, 0.016cm3(ii) in terms of/g. Average pore diameter of
The slow release carrier can be prepared from non-crystalline SiO with high content2(silicon dioxide) and a large amount of amorphous Al2O3(alumina) composition. The high-content amorphous SiO2 (silicon dioxide) can be coal ash, perlite, silica sand, cleaning waste soil, glass waste, waste diatomite, waste casting sand, waste active soil, bagasse ash, ash of burnt agricultural wastes, rice straw ash or natural zeolite powder. Large amount of amorphous Al2O3The (aluminium oxide) is paper making sludge ash, aluminium hydroxide slag, aluminium smelting scum, drainage sludge ash, blast furnace quenching slag, garbage smelter quenching slag or aluminate ion-containing alkaline liquid.
Containing a large amount of amorphous SiO2(silicon dioxide) and a large amount of amorphous Al2O3(aluminum oxide) can be used as a raw material, and is sent into a high-pressure reactor together with alkaline soda (NaOH), and then the slow-release carrier is prepared by precipitation, modification tank, cleaning, transformation, solid-liquid separation and drying.
The above-mentioned preparation method is only one of the preparation methods of the sustained-release carrier of the present invention, and those skilled in the art can use similar or identical materials and use other methods different from the above-mentioned preparation methods to obtain the sustained-release carrier of the present invention. Therefore, the sustained-release carrier of the present invention is not limited to the above-mentioned preparation method.
Please refer to fig. 1, which is an image of the conventional zeolite under a high power electron microscope, it can be seen that the surface of the zeolite is smooth, and there is no pore, if there is a pore, the pore diameter is very small, so that it cannot be applied to the slow release aspect.
Please refer to fig. 2, which is an image of the sustained release carrier of the present invention under a high power electron microscope, it can be seen that the sustained release carrier of the present invention is a porous material, and the pore volume is 0.008 to 0.02cm3Per g, average pore diameter of
The insect prevention/attractant is an insect repellent or a natural mosquito repellent. The insect repellent is Diethyltoluamide (DEET). The natural mosquito-proof liquid is at least two of flos Caryophylli, herba Nepetae Catariae, herba Cymbopogonis Citrari, herba Menthae, herba Rosmarini officinalis, herba Cymbopogonis Citrari, flos Pelargonii Hortori, Lavender, Eucalyptus globulus Labill, and herba Schizonepetae.
The insect repellent/attractant is used for repelling mosquitoes, and if the insect repellent/attractant is used for repelling flies, the insect repellent of the insect repellent/attractant is Xeronine (Cypermethrin), synergestin (Piperonyl), Permethrin (Permethrin) or Pyridinonin (Pyrethrin). The natural fly-preventing liquid of the insect-preventing/attracting agent is citronella, mint, rosemary, lemon grass and geranium.
As mentioned above, the slow release insect prevention/attractant of the present invention is obtained by adsorbing the insect prevention/attractant to a slow release carrier, and then placing the slow release carrier in a spray can, a non-woven fabric bag, a breathable plastic bag, an adhesive or a catching device. The manner of use of the foregoing device will be described below.
In one embodiment, if the sustained release carrier is placed in an aerosol can, the aerosol can spray the sustained release carrier onto the body or a specific location.
The slow release carrier releases the insect prevention/attractant at a slow predetermined rate, can release the insect prevention/attractant in a mode of weeks, months or years, and is dependent on the pore diameter of the fine pores of the slow release carrier, if the pore diameter is larger, the slow release carrier releases the insect prevention/attractant for weeks or months, and if the pore diameter is smaller, the slow release carrier releases the insect prevention/attractant for weeks or years. If the insect-proof/attractant is used for preventing mosquitoes, the mosquitoes cannot tolerate the taste of the insect-proof/attractant, so the mosquitoes can automatically avoid the human body or the specific position sprayed with the slow-release insect-proof/attractant, and people can be prevented from being bitten by the mosquitoes. The slow predetermined rate is weeks, months or years.
Similarly, if the insect repellent/attractant is used for preventing flies, the flies cannot tolerate the smell of the insect repellent/attractant, so that the flies can automatically avoid the human body or specific positions sprayed with the slow-release insect repellent/attractant.
In one embodiment, if the slow release carrier is disposed in the non-woven fabric bag or the air permeable plastic bag, the non-woven fabric bag or the air permeable plastic bag can be placed on the clothes or the specific location, and the use method can be as described above.
Fig. 3 shows that the present invention has a better mosquito repelling effect, but the amount of mosquitoes to be repelled cannot be verified, so the insect prevention/attractant is changed to a commercially available attractant.
The commercial attractant is a semiochemical, a sex pheromone precursor, a sex pheromone mating disruptor that is reactive with the insect and is coppery fly (Cuelure), raspberry ketone, 4- (3-Oxobutyl) phenyl formic acid (4- (3-Oxobutyl) phenyl form), or a raspberry ketone derivative; or Codlelure ((E, E) -8, 10-dodecadien-1-ol), Dotoamicrua B ((Z) -9-tetradecen-1-ol), acetic acid (Z) -11-tetradecenyl ester, Pyrimalure (14-methyl-1-octadecene), Peachflash ((Z) -13-eicosen-10-one); or natural bactericide or natural pesticide, such as engine oil (Machine oils), methylphenyl acetate, alpha-pinene, protein hydrolysate, (Z) -1-tetradecene-1-ol, and Turpentine (Turpentine).
The insect attracting experiment is carried out on the commercial attractant and the slow-release insect prevention/attractant under the preset condition of a set dose. The set dose is 7-10 grams, preferably 7, 8 or 9 grams.
The procedure for the preparation of this experiment was: the above commercial attractant is provided in the sustained release carrier of the present invention. The commercial attractant may be a sex pheromone or an insect-reactive semiochemical. The set dosage is the total weight of the insect prevention/attractant and the slow release carrier.
The active ingredient (attractant) used in column a is about 12% by weight of the set dose. The remaining weight percentages are weight percentages of the coagulant. As shown in fig. 3, within 60 days, column a attracted 30, 62, 105, 133, 168, 220, 270 insects within 1, 3, 7, 10, 14, 30, 60 days, respectively, and failed after 60 days.
The same weight percentage of the attractant used for column a was used for column B, but in the column B experiment, a breathable film of Polyvinyl alcohol (PVA) was further used in an amount of about 4-7 wt%, preferably 4%, 5% or 6 wt%, based on the set dose; about 55-75% by weight of the set dose of a setting agent, preferably 55%, 60% or 65%, the setting agent being gypsum; about 1-3% by weight of the set amount of a water repellent, preferably 1.5%, 2% or 2.5%, the water repellent being water wax.

The waterproof agent is used for isolating moisture so as to prevent the attractant from releasing along with the moisture. The coagulant is used to shape the attractant.
The column C uses the same weight percentage of the attractant as the column a, but in the column C experiment, the permeable membrane is further used in an amount of about 4-7% by weight of the set dosage, and the moisture absorbent is further used in an amount of about 1-3% by weight of the set dosage, preferably 1.5%, 2% or 2.5%, and the moisture absorbent can be water glass.
The weight percentage of the attractant is 12 percent. The weight percentage of the breathable film body is 4-7%. The weight percentage of the coagulant is 55-75%. The weight percentage of the waterproof agent is 1-3%. The moisture absorbent accounts for 1-3% by weight. The attractant, the waterproof agent, the coagulant and the hygroscopic agent are mixed with the slow release carrier according to the weight percentage and then are placed inside the breathable membrane body.
As shown in fig. 3, within 60 days, column C attracted 44, 69, 105, 130, 172, 208, 255 insects within 1, 3, 7, 10, 14, 30, 60 days, respectively, and failed after 60 days.
The column D (the slow-release insect prevention/trapping material) uses the same weight percentage of the trapping agent as the column A, but in the column D experiment, a breathable film body which accounts for about 4-7% of the set dosage by weight is further used; a water-proofing agent accounting for about 1-3% of the set dosage by weight; and about 55-75% by weight of the set dose of a solidifying agent; and about 10-15% by weight of the set dose of a sustained release carrier, preferably 11%, 12%, 13% or 14%.
The weight percentage of the attractant is 12 percent. The weight percentage of the breathable film body is 4-7%. The weight percentage of the coagulant is 55-75%. The weight percentage of the waterproof agent is 1-3%. The weight percentage of the slow release carrier is 10-15%. The attractant, the coagulant, the waterproof agent and the slow-release carrier are mixed and then are placed inside the air-permeable membrane body.
The cylinder D lures 20, 120, 1142, 182, 210, 250, 301, 441, 508, 593 and 623 insects respectively in 1, 3, 7, 10, 14, 30, 60, 80, 120, 150 and 180 days and still keeps effective after 180 days.
The weight percentage of the slow release insect prevention/attracting substance used by the column E is equal to that of the column D, and the column E is the comparison of the column D. The weight percentage of the attractant is 12 percent. The weight percentage of the breathable film body is 4-7%. The weight percentage of the coagulant is 55-75%. The weight percentage of the waterproof agent is 1-3%. The weight percentage of the slow release carrier is 10-15%. The attractant, the coagulant, the waterproof agent and the slow-release carrier are mixed and then are placed inside the air-permeable membrane body.
The column body E lures 55, 107, 131, 155, 193, 220, 278, 407, 443, 551 and 571 insects respectively in 1, 3, 7, 10, 14, 30, 60, 80, 120, 150 and 180 days and still keeps effective after 180 days.
For example, the attractant is the aroma of melons. The above-mentioned attracted insects are fruit flies. But are not limited thereto.
The slow release insect prevention/attractant can use a coagulant to shape the slow release insect prevention/attractant into a solid, such as a pastille, and the solid is coated with a water-proof agent and then coated with a solid with a water-proof agent by a breathable film body.
The insect repellent/attractant of the slow-release insect repellent/attractant can be any one of the water phase, the oil phase or the powder phase or at least any combination of the two.
If the insect-preventing/attracting agent is water phase or oil phase, the slow release carrier can be absorbed into the slow release carrier, and the insect-preventing/attracting agent is released slowly at a preset speed. Similarly, if the insect-repellent/attractant is in powder phase, the slow release carrier can absorb the insect-repellent/attractant in powder phase, i.e. the insect-repellent/attractant is filled in the pores of the slow release carrier and then releases the insect-repellent/attractant at a slow predetermined rate.
The insect-preventing/attracting agent for the slow-release insect-preventing/attracting substance of the present invention may also be an essential oil, for example, the essential oil is citrus, floral, herbal, camphor, woody, spicy, resinous or earthy. For example, if the essential oil is horseradish essential oil, the horseradish essential oil can provide a bactericidal effect, so if the chemical pheromone, sex pheromone precursor, sex pheromone mating disruptor or one or at least two of the insect-preventing/attracting agents are combined with the horseradish essential oil, the slow-release insect-preventing/attracting agent can have a long-term preservation effect, and a natural preservative effect can be achieved.
The insect prevention/luring agent of the slow-release insect prevention/luring object can also be chili oil. Similarly, if the insect repellent/attractant is also capsicum oil, the capsicum oil is filled in the pores of the slow release carrier and then released at a slow predetermined rate. The capsicum oil has an irritant odor, so that rodent such as mouse can be repelled.
In summary, the slow release insect prevention/attraction material of the invention utilizes the characteristic that the slow release carrier has the slow release of the adsorbed substances, and the time efficiency is up to weeks, months and years, so that a small amount of insect prevention/attraction agent can achieve the long-term and effective mosquito or fly prevention effect.
The foregoing embodiments are provided to illustrate the features and advantages of the present invention, rather than to limit the scope of the invention, which is defined by the claims appended hereto, and all changes and modifications that come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
