Description

Roll trap for trees with biodegradable insect repellent film and manufacturing method thereof {ROLLTRAP FOR TREE HAVING BIODEGRADABLE MOTHPROOF FILM AND METHOD THEREOF}

The present invention relates to a tree roll trap having a biodegradable insect repellent film and a method for manufacturing the same, and more particularly, for a tree having a biodegradable insect repellent film that is installed in a tree to kill pests and is decomposed by microorganisms after a certain period of time. It relates to a roll trap and a manufacturing method thereof.

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 on the trees, as described above, penetrates through the tree trunk of the tree corresponding to the height of about 1.5 m (the specific tree is higher than this) from the bottom of the tree and invades 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 film-type roll trap coated with a viscous adhesive and a sticky insect repellent liquid on both sides is wrapped on a tree to shield the tree's sheath. As a result, a way of infesting pests has been developed.

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 film 60a as shown in an enlarged cross sectional view of the drawing; An adhesive layer 60b; It includes; and the attracting layer (60c), it may further include a attracting layer (61).

The film 60a may be composed of a thin film of soft vinyl or a biodegradable fibrous fabric. The film 60a is wound and fixed to the bobbin 69 in a state in which 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 film 60a as shown in enlarged form to form one layer. This adhesive layer 60b is composed of a viscous adhesive. In particular, the adhesive layer 60b is composed of an adhesive that is adhered to the outer skin of the tree as described below. That is, the adhesive layer 60b is composed of an adhesive that can be easily separated from the outer skin of the tree later.

The adhesive layer 60b may be composed of, for example, 20 wt% to 30 wt% of paraffin, 35 wt% to 40 wt% of EVA (Ethylene Vinyl Acetat), and 30 wt% to 40 wt% of a mixture of gum rosin and 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 film 60a positioned opposite to the adhesive layer 60b as shown in an enlarged view. The foam layer 60c may be composed of sticky sticky material. 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 film 60a as the sticky is applied to the other side 64 of the film 60a.

The kill layer 60c may be provided with a attracting layer 61 on one side as shown. This attracting layer 61 is preferably provided in the form of a band in the middle of the spray layer (60c) as shown.

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 pests, and the aforementioned attractants are preferably composed of pheromone or pest-preferred foods composed of mucus or powder. .

Attracting layer 61 may be configured by mixing the pheromone of a 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 film 60a is composed 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 decreases the biodegradation rate when the biodegradable aliphatic polymer is mixed at 30 parts by weight or less with respect to 100 parts by weight of polyethylene, and when the biodegradable aliphatic polymer is mixed by 70 parts by weight or more.

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 to 40:60 wt% to prepare the above-described film 60a. That is, since the period of 2 months is a period for controlling pests, the shape of the film 60a described above is maintained for 2 months by the biodegradable accelerator mixed at the above-mentioned ratio, and decomposes after 2 months have elapsed. At this time, the biodegradable accelerator is to increase the mixing ratio of corn pellets and lower the mixing ratio of corn chips, it is possible to increase the shape retention period of the film (60a).

Corn pellets are formed by adding a mixture of corn powder and water at 25 to 30 wt%: 70 to 75 wt% to form syrup, and 2 to 5 wt% liquefied enzyme is added to the syrup to ferment to form sugar water. Sugar water is obtained by drying, solidifying and grinding. At this time, the corn pellet is formed into fine grains of about 50 ~ 150 mesh by the grinding process. Here, corn pellets have a suitable viscosity when the mixing ratio of corn powder and water is 25-30 wt%: 70-75 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 with stirring by adding 5 to 40 parts by weight of corn powder to 100 parts by weight of alcohol solution, which is 70 to 100% alcohol, dried by hot air at 50 to 80 degrees, processed into solids, and then pulverized immediately. 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 film, the corn pellets and corn chips are excellent in 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 easily mixed with the matrix resin due to the difference in particle size during film production. 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, the 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 when used for a certain period of the film (60a) produced by them 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 include wax, candellia wax, rice wax, carnauba wax, castor-wax, soybean cured oil, montan wax, paraffin wax, and 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 the 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 catalyst used 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 film 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 film 60a is formed in the thickness of 30-60 micrometers. Since the film 60a is formed to have a thin thickness, the wound thickness is thin and thus is easy to carry.

This, the film 60a is exposed to the air after a certain period of time in the state exposed to the air by a thin thickness is naturally decomposed to the air, or when buried in the soil is finally decomposed into water and carbon dioxide by the microorganisms in the soil or water. .

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

On the other hand, the film 60a further includes an adhesive tension portion 68 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 film 60a. Here, the hole may be formed in a large amount using a roller having a plurality of pins formed in the film 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 film 60a. In addition, since the adhesive tensile portion 68 discharges the moisture inside and inflows the fresh air from the outside, the humidity is kept below a certain level inside the film 60a, so that 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.

This, the attachment table 70 is made of the same material as the film 60a and is formed in the form of a flexible 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, as shown in the enlarged perspective view on the drawing, the attachment table 70 is provided with a management status table 72 in which contents such as a control date, a removal date, a bottle name, and a remark are described.

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.

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.

As such, the mixed matrix resin, the biodegradable accelerator and the additive are formed into a dough and then extruded and extruded into a thin film. At this time, the dough is extruded at a temperature of 150 degrees and a screw speed of 80 rpm in an extruder, and then re-extruded at a temperature of 200 degrees and a screw speed of 300 rpm to prepare a thin film. 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 composed of 20-30 wt% of paraffin, 35-40 wt% of EVA, and 30-40 wt% of a mixture of glycerin in gum rosin on one side of the film.

Subsequently, a viscous sticky material is formed by attaching a pest that penetrates into the tree on the other side of the film to kill and to form a kill layer.

Subsequently, a attractant layer that attracts pests is formed in a part of the killing layer.

Furthermore, the release paper which shields and protects an adhesive layer or a foam layer is peelably attached to an adhesive layer or a foam layer.

Finally, the film with release paper is wound on the bobbin.

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

Referring to Figure 3, the wood lapping roll trap 60 according to an embodiment of the present invention as described above is wound between the trees 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.
