Description

Loess spray for protecting and wound healing for trees

It relates to ocher spray for protecting trees and treating wounds.

When a tree is injured by an external factor, it is necessary to prevent moisture evaporation from the wounded area for restoration and protection of the wound. However, since the conventional artificial bark contains chemicals such as adhesives, pesticides and preservatives as main components, there is a risk of environmental pollution or side effects.

On the other hand, there is a treatment method to prevent the progress of decay by filling the dead area generated by the decay of the above-ground part of the tree, such as urethane foam or cement, to prevent moisture from penetrating from the outside. However, the above method only exerts a temporary stopping effect, such as preventing the propagation of putrefactive bacteria present in the generated decay site or reducing the rate of decay due to continuous water penetration, and the treatment site is reopened after a long period of time. Therefore, there is a problem that requires continuous treatment. In addition, it is easy for pests to invade from the wounded part, and the death of trees can proceed rapidly. In addition, the existing treatment method has a disadvantage in that it requires excessive construction equipment and manpower by applying a protective material to a tree wound.

Therefore, there is a need to develop an ocher spray that prevents the rapid progression of tree death by preventing the penetration of pests into the wounded area, and is effective in protecting trees and treating wounds as well as containing eco-friendly materials that can be easily installed.

One aspect is to provide a composition for loess spray comprising loess, water, an insecticide and a thickener.

One aspect provides a composition for loess spray comprising loess, water, an insecticide and a thickener.

In this specification, the term "loess" is a natural material deposited by convection and weathering, and is called living and breathing life energy because it absorbs and stores solar energy for a long period of time. In addition, loess has uniform particles and provides good water permeability due to its porosity. The particle surface of loess has a wide honeycomb structure, and it has a multi-layered structure with numerous spaces. In such a sponge-like hole, a large amount of far-infrared rays are absorbed and stored, and when they receive heat, they are emitted to stimulate the molecular activity of other objects and promote growth. In addition, loess has excellent purification ability, so it has excellent deodorization, antibacterial, insect repellent, fungal growth inhibition and dehumidification effects, and has about twice the amount of oxygen compared to the amount of oxygen in the air. . In addition, loess contains natural enzymes such as cadalase, piphenol oxidase, and cyclase protease, thereby providing toxin removal, decomposition, and purification action.

In the present specification, the term "spray" is used to spray the composition stock solution in the form of liquid droplets or solid particles having a size of 100 μm or less, that is, in the form of an aerosol, and is used to fill the gaps in the withering site of trees. The composition for spraying ocher is applied to the wound site where the bark is peeled off without causing damage to the living flow cells of the xylem and the cambium cells under the bark at the edge of the wound to prevent pathogens from entering through the wound. . In addition, by spraying on a tree, it is possible to treat a wound and protect a tree, so it is more economical than the existing method because it does not require excessive construction equipment or manpower.

The composition for spraying loess according to an aspect has an effect of preventing the progress of decay by preventing moisture penetration into the dead site. It can also heal wounds on trees and protect damaged areas from pests, fungi or bacteria. In addition, it is possible to protect the tree from the external environment and heal damaged wounds, as well as help the growth and physiological activity of the tree. In addition, during a heat wave, the temperature of the trunk of a tree is lowered to increase the photosynthesis rate, and it can have a direct or indirect effect on trees and humans using the same through far-infrared rays and generation of negative ions. Therefore, the composition for spraying ocher according to an aspect may be for protecting trees or treating wounds or repelling pests. The pests are insects that harm trees, and include, for example, pine needle flies, pine bark caterpillars, pine moths, pine beetles, cypress broadleaf, pine yellow spot weevil, white pine weevil moth, and pine needle moth.

In one embodiment, the composition for spraying ocher may include 40 to 48% by weight of loess, 30 to 42% by weight of water, 3 to 5% by weight of insecticide, and 3.5 to 7.5% by weight of thickener based on the total weight of the composition. .

The loess may be included in an amount of 40 to 48% by weight based on the total weight of the composition stock solution. The loess is, for example, 40 to 48% by weight, 40 to 46% by weight, 40 to 44% by weight, 40 to 42% by weight, 42 to 48% by weight, 42 to 46% by weight, based on the total weight of the loess stock solution composition, 44 to 46% by weight or 46 to 48% by weight may be included. At this time, when the content of the loess is less than the above range, there is a problem in that the purifying, sterilizing or protective effect, which is the inherent function of loess, cannot be sufficiently exhibited. In addition, when it exceeds the above range, the powdering according to the drying of the loess composition undiluted solution is increased, the application stability of the damaged area is reduced, the concentration of the loess undiluted solution is excessively high, the nozzle is clogged during spraying, or the surface hardening time is increased. , there is a problem that a crack is generated by spraying thickly on the target site.

The water may be included in an amount of 30 to 42% by weight based on the total weight of the composition. The water may be included in, for example, 30 to 42% by weight, 30 to 40% by weight, 33 to 40% by weight, 35 to 41% by weight, or 39 to 41% by weight based on the total weight of the composition. At this time, when the content of water is less than the above range, the viscosity of the loess composition is excessively high, so it may be difficult to implement a spray formulation, and there is a problem in that the shape of the spray and the texture of the surface after spraying are rough when spraying. In addition, when exceeding the above range, the viscosity of the loess composition is low, so it is difficult to spray on the target site, and there is a problem in that the composition flows without being attached (fixed) when spraying. That is, by including a specific amount of water of the loess composition according to an aspect, it is possible to adjust the optimum viscosity so that the loess composition can be sprayed by a spray nozzle.

The insecticide may be a natural or eco-friendly insecticide, and may be added to the loess composition to maximize the insect repellent and/or sterilization effect, which is a unique characteristic of loess. The pesticide is, for example, phytoncide, grass vinegar, magma Q, herbal oil (lavender, rosemary, lemon rice, lemongrass), citronella, pyrethrum, jagong, ginseng, fig leaf, ginkgo leaf, oleander, cheonnamseong, Potato leaves, tobacco leaves, cosmos, hot peppers, bracken, porridge, American radish, stems, red potatoes, pork potatoes, paw paw tree leaves, bark, cinnamon, horsetail, chives, onion, garlic, mugwort, pine needles, green tea leaves, perilla , Reed, Shinwoodae, Balsam, Eoseongcho, Cypress, Sorijae root, Lacquer, Ginkgo, Dandelion, Maekmundong, Plum, Arborvitae fruit, Peach tree leaf, Paulownia leaf, Halpinus flower, Convolvulaceae, Spinachweed, Mint, Jarigong, Seokchangpo , neem oil, derris oil, or an extract of a mixture thereof. The pesticide may be included in an amount of 3 to 5% by weight based on the total weight of the loess composition stock solution. The pesticide may be included in, for example, 3 to 5% by weight, 3 to 4% by weight, 3.5 to 5% by weight, 3.5 to 4.5% by weight, 4.5 to 5% by weight, or 4 to 5% by weight based on the total weight of the composition. can At this time, when the content of the insecticide is less than the above range, there is a problem that the insecticidal effect on pests, fungi or bacteria is not sufficiently exhibited. There is a problem in damaging cells.

The thickener is for enhancing the viscosity of the ocher composition, and may be a cellulose-based thickener, an acrylic-based thickener, a stitch-based thickener, or a gum. The thickener may be included in an amount of 3.5 to 7.5% by weight based on the total weight of the composition. The thickener is, for example, 3.5 to 7.5% by weight, 4 to 7.5% by weight, 4.5 to 6.5% by weight, 5 to 7% by weight, 5.5 to 7.5% by weight, or 6.5 to 7% by weight based on the total weight of the composition. can At this time, when the content of the thickener is less than the above range, there is a problem that the viscosity of the loess composition undiluted solution is low, so that it is not fixed to the damaged part of the tree and cannot effectively protect it from moisture penetration after application, and when it exceeds the above range, There is a problem in that it is difficult to apply to the damaged part of the tree by blocking the discharge part of the spray exposure because the viscosity is too high.

In one embodiment, the composition for spraying loess may further include an electrodeposition agent. The electrodeposition agent not only provides spreadability and bonding strength of the loess composition, but also prevents loss of the coating film due to the external environment. The spreading agent may be, for example, polyoxy ethylene alkyl arylether, sodium ligno sulfonate, wheat paste, rice paste, starch powder, or the like. The spreading agent may be included in an amount of 1 to 10% by weight based on the total weight of the composition. The spreading agent is, for example, 1 to 10% by weight, 1 to 8% by weight, 1 to 7% by weight, 1 to 5% by weight, 2 to 9% by weight, 2 to 8% by weight, 2 to 6% by weight, 3 to 6% by weight or 4 to 7% by weight. At this time, if the content of the electrodeposition agent is less than the above range, there is a risk that the film applied to the damaged area may be lost due to an external environment such as wind and rain due to the weak bonding force between the tree and the loess composition. There is a problem in that the film is not uniformly formed on the damaged part of the tree.

In addition, it may include 1 to 5% by weight of a curing agent, and 1 to 15% by weight of a filling gas (filler) based on the total weight of the composition for spraying. The curing agent may be, for example, a protein-based natural resin, a carbohydrate-based natural resin, a starch-based natural resin, a cellulose-based natural resin, or a complex polysaccharide-based natural resin. In one embodiment, the curing agent may be included in an amount of 1 to 5% by weight, 1 to 4% by weight, 2 to 5% by weight, or 3 to 4% by weight based on the total weight of the composition. At this time, when the content of the curing agent is less than the above range, after application of the composition for spraying, coating durability is deteriorated, so that it is difficult to sustain for a long time. In addition, when it exceeds the above range, the viscosity of the loess undiluted solution composition may increase to generate bubbles, or the spraying composition may not spread evenly during spraying and the spraying angle may be narrowed. In addition, there is a problem in that the remaining amount buried in the nozzle is quickly cured after spraying, and the discharge port is clogged. In addition, the filler may be, for example, LPG, CFC, or the like. In one embodiment, the filler may be included in an amount of 1 to 15% by weight, 1 to 10% by weight, 1 to 8% by weight, 5 to 8% by weight, or 3 to 7% by weight based on the total weight of the composition. At this time, when the content of the filler is less than the above range, there is a problem that it is not evenly sprayed to the target site, and when it exceeds the above range, there is a problem that the dispersing power of the spray composition is excessively strong.

In one embodiment, it was confirmed that when the ocher spray composition containing the loess composition undiluted solution was sprayed on the fire generator, no sparks were generated. Therefore, in one embodiment, the composition for spraying ocher may not contain a volatile material. The volatile material may be, for example, a volatile organic compound (VOC), a semi-volatile compound (SVOC), or the like. Therefore, the composition for spraying ocher according to an aspect does not contain a volatile material, so it can be sprayed directly on a tree, and there is no risk of fire, so it can be easily used to treat a wound on a tree or to protect a tree.

In another example, the difference in spraying force according to the nozzle size of the composition for spraying loess was confirmed. Accordingly, the composition may be sprayed from a spray nozzle having a size of 0.65 to 1 mm. The size of the nozzle may be, for example, 0.65 to 1 mm, 0.65 to 0.9 mm, 0.65 to 0.8 mm, or 0.7 to 0.75 mm. At this time, when the size of the nozzle is less than the above range, there is a problem that the composition for spraying is not sprayed and solidifies around the discharge port. In addition, when it exceeds the above range, the spray radius is narrow when spraying the composition for spraying, so the workability is lowered, and the composition is agglomerated at the spraying site, so there is a problem in that the spreadability is uneven.

Another aspect provides a spray device comprising a nozzle having a size of 0.65 to 1 mm in which the composition for spraying loess according to an aspect is supported. Specific details of the composition for spraying loess are the same as described above.

Another aspect provides a method of protecting trees, treating wounds or exterminating pests, comprising spraying the composition for spraying yellow soil according to an aspect to trees. Specific details of the composition for spraying loess are the same as described above. In one embodiment, the method may include drying after applying the composition for loess spray to a target site of a tree. The target site may be, for example, a tree dead site, a decay site, a wound site, or a damaged site. Therefore, according to the above method, it is possible to effectively protect the vestibular region by inhibiting the evaporation of moisture to prevent splitting of trees.

The loess composition according to an aspect can be applied directly to a wound on a tree to treat the wound as well as protect the damaged area from pests, fungi or bacteria.
