Description

Tree Roll Trap {ROLLTRAP FOR TREE}

The present invention relates to a tree roll trap, and more particularly, to a tree roll trap installed in the tree to kill pests and decomposed by microorganisms after a certain period of time.

Insects generally refer to insects that cause damage against the management purpose of the tree. These pests are mainly active from spring to autumn, damaging trees. Pests vary according to the climate, and are assessed differently depending on the distance from the housing site or factory, the terrain or other environmental factors.

Until the mid-1970s, four pests in the forest, including pine moth, pine needle hog flies, American white moth, alder leaf beetle, and pine rust, became a major problem. The damage of pine needles and other pine needles is continuously spreading, and new pests such as pine bark beetle, pine nut leaf beetle, pyrite beetle beetle, and plane beetle are appearing. In particular, oak wilting disease has become a major problem due to the activity of the Gwangneung long-tree, which is a pest that mediates the formation of fungi in trees, and is also located in the trunks of vines, weighted trees, cedar trees and plane trees. The problem of scarlet wing cicada (aka cicada) that damages the back is emerging rapidly.

The above-mentioned Gwangneung long tree is inhabited by males penetrating through the trunks of oaks, chestnuts, cypresses, ashes, etc., and males lure females into the puncture space by attracting females with pheromones. In the Gwangneung long tree, the Acrocia bacteria of the genus Raffaelea on the back of a deceased female are transmitted to the inside of the tree to destroy the tree's conduit and the like. In addition, the above-mentioned scarlet wing cicada vigorously clings to fruit trees such as vines and sucks sap. Therefore, forests and horticultural farms are severely damaged by Gwangneung long tree beetle and scarlet wing cicadas, respectively.

Here, the above-mentioned fungal pests that produce fungi in the trees, as described above, invade through the tree trunks of the trees corresponding to the height of about 1.5 m (the specific tree is higher than this) from the bottom of the trees. Infarct the conduit. In addition, the above-mentioned absorptive pest adheres to the outer shell of the liver and absorbs the sap, thereby obstructing the flow of the sap. Thus, trees are eventually killed by these pests.

On the other hand, in order to conveniently combat such perforated fungal pests, in recent years, a tape-shaped roll trap coated with a viscous adhesive and a sticky insect repellent on both sides is wrapped on the tree to shield the tree's sheath. As a result, a way of infesting pests has been developed.

Applicant of the present invention has been filed and registered with the Republic of Korea Patent Office Patent Application No. 10-2009-108958 'method of pest control by trees lapping roll trap'.

The roll trap disclosed in the patent is applied to the inner surface of the soft thin film base layer and the base layer and adhered to the outer skin of the tree, and is formed on the outer surface of the bay layer and is formed of viscous sticky to kill pests. It is composed of layers. The roll trap having such a configuration is allowed to stand by a sticky layer of the killing layer of pests that are left for a certain period of time (2 to 3 months) while being wound on the tree and approaching the tree.

However, since the conventional roll trap is left on the tree for a certain period of time (2 to 3 months) to kill pests, the roll trap that has been left after a certain period (2 to 3 months) must be recovered. That is, since the base layer of the roll trap is manufactured in the form of a thin film tape using synthetic resin, there is a problem in that it does not interfere with the growth of the tree while being wound on the tree without biodegradation even after a certain period of time.

In addition, when the base layer of the roll trap is peeled off from the trees by external factors, the soil is not covered by the soil or buried in the soil so that air in the air is not provided to the soil. There is also.

Therefore, the base layer of the roll trap has a cumbersome problem to be recovered by the workers after the leaving period.

The present invention has been made to solve the above problems, a viscous adhesive is applied to one side to shield the outer skin of the tree, to provide a wood roll trap containing a attractant material that attracts pests using reflected light For that purpose.
In particular, it is another object of the present invention to provide a tree roll trap which can be biodegradable after a certain period of time while controlling the pests of the tree for a predetermined period of time while the tape is made of a water-soluble material wound on the tree.

Another object of the present invention is to provide a roll trap for a tree which is decomposed after a certain period of time while controlling pests of the tree for a predetermined period of time while the tape is made of paper and wound around the tree.

Hereinafter, the present invention will be described with reference to the accompanying drawings.

Referring to Figure 1, the tree-lapping roll trap 60 according to an embodiment of the present invention is rolled to form a rolled bobbin 69 as shown. This roll trap 60 includes a tape 60a as shown in an enlarged cross-sectional view on the drawing; Adhesive layer 60b; A spray layer 60c; And a attracting layer 61.

The tape 60a is a biodegradable thin film material that provides both sides of a set width. The tape 60a may be made of air permeable and biodegradable paper, soft vinyl, or biodegradable fibrous fabric.

Here, the paper is composed of biodegradable kraft paper, the soft material vinyl may be a conventional thin-film vinyl, the biodegradable fibrous fabric may be composed of a non-woven or woven fabric. The tape 60a is wound around and fixed to the bobbin 69 in a state where the adhesive layer 60b and the spray layer 60c are applied to both sides.

On the other hand, the adhesive layer 60b is applied to one side 63 of the tape 60a, as shown in an enlarged view, and is formed of a viscous adhesive to form a single layer and adheres to the outer shell of the trees forming the tree. That is, the adhesive layer 60b is composed of the same material or adhesive composition as the gundam layer 60c to be described later to be easily separated from the outer skin of the tree.

The adhesive layer 60b may be composed of, for example, 20 wt% to 30 wt% of paraffin, 35 wt% to 40 wt% of ethylene vinyl acetate (EVA), and 30 wt% to 40 wt% of gum rosin glycerin. Such an adhesive layer 60b may secure adhesiveness about 2 months before and after the aforementioned component. That is, the adhesive layer 60b exhibits adhesiveness for a certain time by the above-described components.

The spray layer 60c is provided on the other side 64 of the tape 60a positioned opposite to the adhesive layer 60b as shown in an enlarged view. The killing layer 60c is composed of a common sticky substance having a viscous property, and can be killed by attaching a pest that invades the tree. That is, the foam layer 60c may be made of a sticky material in a gel form. The foam layer 60c is integrally provided on the tape 60a as the sticky is applied to the other side 64 of the tape 60a.

On the other hand, the above-described adhesive layer 60b may be composed of a mixture of hydrophilic and insect repellent material. Such materials may consist of, for example, charcoal powder or ocher powder. At this time, the charcoal powder or ocher powder may be used alone, or alternatively, may be mixed with the adhesive layer 60b in a mixed form.

On the other hand, the above-described killing layer 60c may be composed of a sticky mixture of insecticides or attractants. Of course, in this case, the above-mentioned attracting layer 61 is not provided in the killing layer 60c. Here, the pesticides described above are preferably composed of oral pesticides processed to be consumed by the pests, and the aforementioned attractants are preferably composed of pheromones or pest-preferred foods composed of mucus or powder. Do.

The attracting layer 61 may be provided in the killing layer 60c as shown. Attracting layer 61 is composed of a reflector powder or a plurality of pieces of reflector and mixed in the killing layer 60c to attract pests. Such a reflector powder or a plurality of pieces of reflector may be composed of pulverized silver foil and mixed with the spraying liquid. Alternatively, the attracting layer 61 may be provided in a band shape in the middle of the spray layer 60c as shown.

This, attracting layer 61 can be configured by mixing the pheromone of the particular pest on the sticky. Alternatively, the attractant layer 61 may be configured by mixing the powder with a preferred food of a particular pest on the sticky. Of course, the attractant layer 61 may be configured by spraying pheromone or preferred food powder on the surface of the middle portion of the foam layer 60c.

On the other hand, the tape 60a is a thin film made of a matrix resin, a biodegradable accelerator, a binder, a commercial catalyst, a radical initiator, a starch plasticizer and a starch bond breaker. Here, the biodegradable accelerator is 10 to 70 parts by weight based on 100 parts by weight of the matrix resin, the binder is 0.1 to 10 parts by weight based on 100 parts by weight of the matrix resin, and the commercial catalyst is 0.1 to 10 parts by weight based on 100 parts by weight of the matrix resin. Part, the radical initiator is 0.001 to 1 part by weight based on 100 parts by weight of the matrix resin, the starch plasticizer is 1 to 40 parts by weight based on 100 parts by weight of the matrix resin, and the starch bond destructor is 0.01 to 100 parts by weight of the matrix resin. It is -20 weight part.

The matrix resin is composed of a mixture of polyethylene, biodegradable aliphatic polymer, natural latex, and curing agent. Polyethylene has excellent processability and physical properties. Biodegradable aliphatic polymers are used to improve their degradability due to their excellent biodegradability. Natural latex provides elasticity when mixed with tissues. Curing agents promote curing while increasing hardness.

Here, the polyethylene is preferably low density polyethylene, linear low density polyethylene, or high density polyethylene. Biodegradable aliphatic polymers include polycaprolactone, polylactic acid, and alcohols article The CH ₂ is 1-6 introducing a diol (Diol), a carboxylic acid group and the CH ₂ is 1-6 introducing a di Acid (Diacid) between the alcohol Aliphatic polyesters and copolymers thereof polycondensed with a hydroxyexide having 1 to 6 CH ₂ introduced between the group and the carboxylic acid group can be used.

Here, the matrix resin is composed of 30 to 70 parts by weight of the biodegradable aliphatic polymer, 6 to 15 parts by weight of the natural latex and 3 to 15 parts by weight of the curing agent are mixed with respect to 100 parts by weight of polyethylene. Such a matrix resin can control the water resistance and biodegradability by adjusting the weight between 30 to 70 parts by weight based on 100 parts by weight of the biodegradable aliphatic polymer. In addition, when the biodegradable aliphatic polymer is mixed at 30 parts by weight or less with respect to 100 parts by weight of polyethylene, the biodegradation rate is lowered, and when the mixture is 70 parts by weight or more, the physical properties are lowered.

In addition, the biodegradable accelerator is composed of granulated corn pellets and powdered corn chips at a ratio of 40 to 55 wt%: 45 to 60 wt%. Such a biodegradable accelerator may be decomposed after about two months when the mixing ratio of corn pellets and corn chips is mixed with 40:60 wt% to produce the aforementioned tape 60a. That is, since the period of two months is a period for controlling pests, the shape of the above-described tape 60a is maintained for two months by the biodegradable accelerator mixed at the above-mentioned ratio, and decomposes after two months have elapsed. At this time, the biodegradable accelerator to increase the mixing ratio of corn pellets and to lower the mixing ratio of corn chips, it is possible to increase the shape retention period of the tape (60a).

Corn pellets are formed by adding water added with corn powder to form syrup, followed by fermentation by adding 2-5 wt% of liquefied enzyme to 95-98 wt% of syrup to form sugar water, and drying the formed sugar water to solidify and grind it. Obtained by. At this time, the corn pellet is formed into fine grains of about 50 ~ 150 mesh by the grinding process. Here, the corn pellets have a suitable viscosity when the mixing ratio of corn powder and water is 25 to 35 wt%: 65 to 75 wt%. At this time, since the viscosity of starch syrup increases when the mixing ratio is increased, fermentation by liquefied enzyme is slow. In addition, the corn powder takes a long time to form starch syrup when the mixing ratio is reduced.

Corn chips are fermented while stirring by adding 5 to 40 parts by weight of corn powder to 100 parts by weight of alcohol solution of 70 to 100% alcohol, dried by hot air at 50 to 80 degrees, processed into solids, and then immediately crushed into powders. Can be configured. At this time, the corn powder may be rapidly volatilized so that solidification may proceed rapidly. Here, the corn powder is not easy to stir when more than 40 parts by weight with respect to 100 parts by weight of the alcohol solution, the stirring is not easy to fermentation is not easily made. In addition, corn powder may be incinerated when dried at a temperature of 80 degrees or more during hot air drying, it is slow to dry when dried to 50 degrees or less.

However, the corn chips are rapidly frozen in the freezer to -10 degrees to -40 degrees in a freezer, lyophilized in a freeze dryer for 24 hours, and then pulverized first in a freeze-dried state in a grinder to 120 mesh, It may also be composed of a powder of fine particles obtained by secondary grinding with 200 mesh.

In this case, the corn chips are dried at low temperatures, and thus are easily dried without deformation due to heat. In more detail, corn chips are hard to be pulverized into small particles because the structure is shrunk by hot air drying, thereby increasing hardness and compressive strength. Therefore, the corn chips, as described above, are weakened in hardness and compressive strength when rapidly frozen and lyophilized, and the tissues are transformed into porous, and are easily crushed into fine particles. Therefore, the corn chips thus processed are easy to dry due to their small size, and are excellent in redissolution for water after drying. In addition, corn chips are easy to store at room temperature when crushed in a lyophilized state.

On the other hand, corn chips have excellent solubility in water when crushed to 200 mesh, solubility in water when crushed to less than 120 mesh, it is not easy to transport and store when crushed to more than 200 mesh.

On the other hand, since the corn pellets and corn chips are formed into starch through the fermentation process as described above, after being manufactured into a tape, the corn pellets and corn chips have excellent re-dissolution for water, and thus have excellent biodegradability.

In addition, since the corn pellets are formed in a granular form, and the corn chips are formed in a powder form, the corn pellets and the corn chips may be fused while being easily mixed with the matrix resin due to the difference in particle size during tape manufacturing. That is, since the powdered corn chips are particles of a relatively small size with respect to the corn pellets, it is easy to adjust the viscosity by adjusting the amount mixed with the corn pellets.

The hardener includes 1 to 100 parts by weight of cellulose derivative, 1 to 50 parts by weight of filler, 0.5 to 30 parts by weight of plasticizer and 0.1 to 5 parts by weight of water repellent, based on 100 parts by weight of natural wax. Here, when the hardening agent is 100 parts by weight and 50 parts by weight or more with respect to 100 parts by weight of the natural wax, the viscosity is increased to increase the strength and the productivity is lowered.

Such a curing agent is cured in a mixed state of polyethylene, biodegradable aliphatic polymer and natural latex using a plant-based natural wax, cellulose derivatives, fillers, plasticizers and water repellents, so that the tape 60a produced by them is used for a certain period of time. It can increase the water resistance and biodegradability at the time of disposal after a certain period of time, and can control the balance by adjusting the amount of natural wax blended.

Natural waxes may be wax, candellia wax, rice wax, carnauba wax, castor-wax, soybean cured oil, montan wax, paraffin wax, or the like. The cellulose derivative is a) cellulose acetates such as cellulose acetate, cellulose acetate, cellulose triacetate, methyl acetate, cellulose acetate butyrate, cellulose acetate propionate, cellulose acetate phthalate, nitrocellulose, and other cellulose esters; b) cellulose esters such as ethyl cellulose, benzyl cellulose, cyanoethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, hydroxypropyl methyl cellulose, and carboxymethyl cellulose; and the like, and cellulose acetate and cellulose. Acetate butyrate, cellulose acetate propionate are particularly preferred.

As the filler, an inorganic filler and an organic filler are used. As the inorganic filler, for example, silica, synthetic mica, titanium oxide, gold mica pigment, white mica pigment, talc, mud, kaolin, aluminum hydroxide, calcium carbonate, barium sulfate, satin white, pulp, cellulose and the like are used. As the organic filler, for example, acrylic resin, acrylonitrile resin, polyurethane, polyvinyl chloride, polystyrene, polyacrylonitrile, polyamide, silicone resin, fluorine resin or the like can be used. In particular, the filler is preferably made of a biodegradable resin, and can be biodegraded to further reduce the environmental load.

The plasticizer may be phthalic acid diester, tetrahydrofutal acid ester, aliphatic dibasic acid, trimellitic acid ester, epoxy hexahydrophthalic acid ester, epoxidized ester, adipic acid ester, phosphate ester or the like. have. The plasticizer expresses a plasticizing effect to increase thermoplasticity, thereby facilitating molding at high temperatures, and also improves heat resistance, cold resistance, flame resistance, and electrical properties.

The water repellent may be silicone oil, silicone resin, fluorine resin, synthetic wax, or the like.

The binder may be selected from the group consisting of maleic anhydride, metalcrylic anhydride and maleimide. The compatible catalyst may be acrylic acid or metal acrylic acid.

Radical initiators include benzoyl peroxide, di-tributyl peroxide, azobisisobutylonitrile, tributyl hydroperoxide, dicumylperoxide, rupersol 101 (from Pennwalt, 2,5-Dimethyl 2,5-di) t-butylperoxy) hexane) or percardox-14 (manufactured by AKZO, 1,3-Bis (t-butylperoxy-isopropyl) benzene) and the like can be used.

The starch plasticizer may be ethylene glycol, propylene glycol, polyethylene glycol, sorbitol, glycerin (glycerol) or a mixture thereof.

In addition, starch bond destructive agents may be used for urea (Urea), paratoluene sulfonamide, paratoluene sulfonic acid, melamine, water, caustic soda and mixtures thereof.

On the other hand, the tape 60a is preferably configured by adding a white or yellow pigment so as to have a color excellent in identification such as white or yellow.

Moreover, it is preferable that the tape 60a is formed in the thickness of 30-60 micrometers. Since the tape 60a is formed to have a thin thickness, the wound thickness is thin, so that it is easy to carry.

The tape 60a is exposed to air after a certain period of time in a state of being exposed to air by a thin thickness, and is decomposed into air and decomposed into water and carbon dioxide by microorganisms in soil or water when buried in soil. .

In addition, the tape 60a preferably has tensile strength of 26.5 N / mm 2 to 29 N / mm 2 and tear strength of 117.6 N / mm to 125 N / mm. That is, the tape 60a is easily wound without being cut in the process of being wound around the tree because a constant tensile strength is maintained. In addition, the tape 60a is not completely cut by the tear strength even when a predetermined portion is torn.

On the other hand, the tape 60a further includes an adhesive tensile portion 68 which is formed to penetrate in the form of a hole in order to bond the adhesive and the sticky to generate tensile force with each other.

The adhesive tensile portion 68 is a hole formed by passing a pin through the tape 60a. Here, the hole may be formed in a large amount using a roller having a plurality of pins formed on the tape 60a. This hole causes the adhesive and the sticky to adhere to each other, so that the adhesive and the sticky do not flow down to the ground in the tape 60a. In addition, since the adhesive tensile portion 68 discharges the moisture inside and inflows the fresh air from the outside, the humidity is maintained below a predetermined level inside the tape 60a, and thus the adhesive force is increased.

On the other hand, the present invention further includes an attachment table 70 describing the control contents of the tree. As shown in the bobbin 69, the attachment table 70 may be rolled in a circular shape and embedded therein.

The attachment table 70 is made of the same material as that of the tape 60a, and is formed in the form of a soft plate that can be folded in a cylindrical shape. A management status table is provided on one side and an adhesive is applied to the other side. That is, the attachment table 70 is provided with a management status management status table 72 in which contents such as a control date, a removal date, a bottle name, a remark, etc. are described on one side as shown in an enlarged perspective view on the drawing.

Such a table 70 is preferably attached to one side of the management status table is printed on the one side by soybean oil ink, or the management status table is printed on the one side by soybean oil ink. Therefore, the attachment table 70 easily decomposes after a certain period of time.

On the other hand, the attachment table 70 may be composed of a thick paper or laminated plastic coated with vinyl, the edge portion may be attached to the inside of the bobbin 69 and fixed by an adhesive such as a bond.

On the other hand, the roll trap 60 may be provided with a release paper 66 as shown in the enlarged cross-sectional view. The release paper 66 may be made of vinyl or vinyl coated paper, and is attached to the adhesive layer 60b or the spray layer 60c to protect the adhesive layer 60b or the foam layer 60c as shown in an enlarged view. do. The release paper 66 is removed when the roll trap 60 is attached to the tree.

Referring to the accompanying drawings, the manufacturing method and operation of the roll trap according to an embodiment of the present invention as described above are as follows.

When the tape 60a is made of kraft paper as shown in FIG. 1, the tape 60a may be wound on the bobbin 69 after the adhesive layer 60b, the foam layer 60c and the attracting layer 61 are formed on the kraft paper.

Referring to FIG. 2, the roll trap according to the embodiment of the present invention first prepares a matrix resin by mixing polyethylene, a biodegradable aliphatic polymer, a natural latex, and a curing agent. Such a matrix resin is made by mixing 30 to 70 parts by weight of a biodegradable aliphatic polymer, 6 to 15 parts by weight of a natural latex, and 3 to 15 parts by weight of a curing agent based on 100 parts by weight of polyethylene.

Then, a biodegradable accelerator is prepared in a ratio of 40 to 55 wt%: 45 to 60 wt% corn pellets and corn chips. Such a biodegradable accelerator is prepared by first preparing corn pellets and then preparing corn chips, and then mixing the prepared corn pellets and corn chips in a ratio of 40 to 55 wt%: 45 to 60 wt%.

Here, the above-mentioned corn pellets are prepared by adding water to which corn powder is added to form syrup, and adding liquefied enzyme to the syrup to ferment to form sugar water. The sugar water is dried to solidify and then pulverized. At this time, the corn pellet is pulverized into fine granules. In other words, corn pellets are mixed with corn powder and water at 25-35wt%: 65-75wt%, and then cooked to make syrup. After mixing 95 ~ 98wt% of the syrup, the liquefied enzyme is mixed at a ratio of 2-5wt%. It is prepared by fermentation to make sugar water, and then drying and grinding sugar water.

The corn chips are fermented by adding corn powder to an alcohol solution, followed by fermentation. The corn chips are dried by hot air, solidified, and then pulverized into fine powder. Such corn chips are preferably prepared by adding 5 to 40 parts by weight of corn powder with respect to 100 parts by weight of alcohol solution of 70 to 100% alcohol, and drying the corn powder mixed with alcohol solution by hot air at 50 to 80 degrees. It is preferable.

As such, the biodegradable accelerators are mixed with the matrix resin at 10 to 70 parts by weight based on 100 parts by weight of the matrix resin.

At this time, the dough is extruded at an extruder at a temperature of 150 degrees and a screw speed of 80 rpm, and then re-extruded at a temperature of 200 degrees and a screw speed of 300 rpm to prepare a thin film of tape. In other words, the dough is made into a film by extrusion. During extrusion, the dough is reacted and extruded in an extruder, so that the binder is grafted onto the polyethylene chain and an ester reaction occurs with the biodegradable accelerator, so that the biodegradable accelerator is chemically bonded to the matrix resin.

Then, an adhesive layer is formed by applying an adhesive including paraffin 20-30 wt%, EVA 35-40 wt%, and gum rosin glycerin 30-40 wt% to one side of the tape 60a.

Subsequently, a pesticide layer 60c is formed by attaching a viscous sticky material that sticks to the other side of the tape 60a by attaching a pest that invades the tree.

Here, a plurality of guide rollers 3 are installed between the recovery roller 2 and the supply roller 1 to guide the movement while preventing the sagging of the tape 60a to be supplied. The container 4 accommodates the spraying liquid and the attractant in a liquid state. The container 4 accommodates the liquid spraying agent and the attractant material supplied from the supply tank 5. Here, the supply tank 5 is maintained in the liquid state without being solidified by the agitator (5a) that is accommodated in the spraying fluid and attracting material therein, by the discharge pipe (5b) connected in a penetrating state on one side The liquid liquor and the attractant are discharged into the container 4. In addition, the discharge pipe (5b) is provided with a heater (5c) for heating the spraying liquid to about 100 ℃ to prevent the spraying liquid discharged to solidify. The coating roller 6 is rotated while the lower end is in contact with the spraying liquid and the attractant material contained in the container 4 about the rotation axis, and the upper part is rotated in contact with the surface of the tape 60a. The spraying liquid and the attractant are applied to the foaming layer and the attracting layer 61. Here, the coating roller 6 may be constantly adjusted by the blade 7 installed on one side of the container 4, the amount of the spraying liquid and attracting material in contact with the lower end. Thus, the application roller 6 can be attached to the correct amount of the killing liquid and attractant material by the blade (7). In addition, the application roller 6 is provided with a pressure roller 8 for pressing the tape 60a from the top so that the tape 60a is in close contact with the surface.

The operation process of the coating device as described above is as follows.

Referring to FIG. 3, the supply tank 5 accommodates the spraying liquid, and contains the sparkling powder or the sparkling flakes, which are attractants. The stirrer 5a stirs the mixing solution and the attractant solution contained in the supply tank 5. The discharge pipe 5b supplies the container 4 with the firing liquid and the attractant material heated by the heater 5c.

Subsequently, the supply roller 1 supplies the tape 60a. The tape 60a moves between the application roller 6 and the pressure roller 8 while passing through the guide roller 3. At this time, the application roller 6 is rotated in contact with the spraying liquid and the attractant material in the container (4). The blade 7 scrapes a certain amount of the spraying liquid and the attractant material in contact with the application roller 6. The pressure roller 8 presses the upper side of the tape 60a so that the lower side is in close contact with the application roller 6, so that the spraying liquid and the attractant material of the application roller 6 can be easily applied to the lower side of the tape 60a. To be attached. The tape 60a is recovered while being wound around the recovery roller 2 in a state where the foaming layer 60c and the attracting layer 61 are formed.

Finally, the tape 60a is detachably attached to the adhesive layer or the killing layer 60c by the release paper 66 which shields and protects the adhesive layer or the killing layer in the process of winding the bobbin 69 in the recovery roller 2. Can be.

On the other hand, the tape produced by the above-described method can form a hole-shaped adhesive tension portion. As such, the adhesive tensile portion may generate a tensile force by adhering the adhesive and the sticky to each side of the tape to each other.

Referring to Figure 4, the tree-lapping roll trap 60 according to the embodiment of the present invention as described above is wound in the trunk of the tree as described below. At this time, the roll trap 60 is wound on the tree while the adhesive layer (60b) is attached to the outer shell of the tree. The roll trap 60 is attached to the tree to expose the killing layer 60c to the outside of the tree. Therefore, the roll trap 60 traps and kills pests through the killing layer 60c. In other words, the pests are approached by the trees for habitat or absorption, and then stuck to the killing layer 60c to be killed.

This roll trap 60 is removed after being attached to the tree for about two months. In other words, the roll trap 60 is detrimental only during the active period of the pest. Activity periods for these pests are usually appropriate in May-June and September-October. Thus, the roll trap 60 decomposes naturally after about two months.

On the other hand, the roll trap 60 attracts and kills more pests when the above-mentioned attracting layer 61 is provided. At this time, the pest is attracted to the killing layer 60c by the pheromone flavor or the flavor of the preferred food provided from the attracting layer 61. The roll trap 60 can reliably kill more pests when the pesticide layer 60c contains the above-described insecticide or attractant. In particular, the roll trap 60 captures the pest more reliably as the pests are collected in the middle of the killing layer 60c when the attracting layer 61 is provided in the middle of the killing layer 60c as described above. can do.

On the other hand, the roll trap 60 may maintain a suitable humidity in the outer shell of the tree when the coal powder or ocher powder is mixed in the adhesive layer (60b). In particular, in the case of charcoal powder to inhibit the bacteria inhabit the outer shell of the tree. Thus, the roll trap 60 not only exterminates pests while attached to the trees, but also provides assistance to tree growth.

On the other hand, the attachment table 70 is attached to the surface of the roll trap 60, that is, the firing layer 60c, to manifest the control situation of the tree. Therefore, the worker can easily manage the tree through the attachment table (70).

On the other hand, the roll trap 60 may be used for other parts (eg, branches) other than the tree trunk, as described above, if additional control is required. At this time, the roll trap 60 is wound around another part of the tree to control. In addition, the roll trap 60 may be attached to the wood already felled to control the wood felled. At this time, the roll trap 60 controls the pests that penetrate the inside of the trees or pests that are introduced into the felled trees. In particular, such a roll trap 60 is wound around the wood piled on the vinyl for fumigation to control. In this case, therefore, it is not necessary to inject the pesticide into the vinyl.

Since the above-described embodiments are merely illustrative of the preferred embodiments of the present invention, the scope of application of the present invention is not limited to the above, and appropriate modifications are possible within the scope of the same idea. Therefore, since the shape and structure of each component shown in the embodiment of the present invention can be carried out by deformation, it is natural that the modification of the shape and structure belong to the appended claims of the present invention.
