Description

Loess putty for protecting and wound healing for trees}

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

When a tree is injured by external factors, it is necessary to prevent evaporation of moisture at the wound site for restoration and protection of the wound. However, conventional artificial bark contains chemicals such as adhesives, insecticides and preservatives as main components, so there is a risk of environmental contamination or side effects.

On the other hand, there is a treatment method for preventing the progress of decay by filling urethane foam or cement, etc., in the area where the withering occurred while the aboveground part of the tree rots so that moisture does not penetrate from the outside. However, the above method only exerts a temporary stopping effect, such as preventing the propagation of putrefactive bacteria present in the decayed area or reducing the progress of decay due to continuous water penetration, and reopening the treated area after a long period of time. Therefore, there is a problem that requires continuous treatment.

Therefore, there is a need to develop a putty composition that prevents the rapid progression of tree death by preventing the penetration of pests into the wounded area and is effective for protecting trees and treating wounds by containing eco-friendly materials.

One aspect is to provide a ocher composition comprising ocher, an insecticide and water.

Another aspect is to provide a method for producing a ocher composition comprising mixing ocher, an insecticide and water.

Another aspect is to provide a method for protecting trees, treating wounds, or exterminating pests, which includes applying the loess composition to trees.

One aspect provides a ocher composition comprising ocher, an insecticide and water. Another aspect provides a ocher putty composition comprising ocher, an insecticide and water.

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, ocher has uniform particles and is porous, providing good water permeability. The surface of the loess particles has a wide honeycomb structure and a multi-layered structure with numerous spaces. In these sponge-like pores, a large amount of far-infrared rays are absorbed and stored, and when heated, they can be emitted to stimulate the molecular activity of other objects and promote their growth. In addition, loess has excellent purifying ability, so it has excellent deodorization, antibacterial, insecticide, mold growth inhibition and dehumidifying effects, and has about twice the amount of oxygen compared to the amount of oxygen in the air. When a disinfectant is added, it can provide a synergistic effect for the destruction of harmful bacteria. . In addition, ocher contains natural enzymes such as catalylase, piphenol oxidase, and shicarase protease, which provide toxin removal, decomposition, and purification.

In the present specification, the term "putty" is a paste-like adhesive made by grinding ocher powder and used to fill gaps in areas where dead trees occur. The ocher putty composition can be applied to a wound where the bark is peeled off and the xylem is exposed without damaging the living 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 one embodiment, it was confirmed that the ocher composition according to one aspect was applied to the woody part of the tree to a certain thickness and no cracks occurred even after 5 hours had elapsed. In addition, it was confirmed that it exhibits excellent insect repellency, insecticidal rate, and insect invasion rate compared to commercially available tree wound protection coating agents and wound treatment agents. That is, the loess composition according to one aspect has the effect of preventing the progress of decay by preventing moisture penetration into the dead area. In addition, it can treat wounds of trees and protect damaged areas from pests, fungi, or bacteria. In addition, it can protect trees from the external environment, treat damaged wounds, and help the growth and physiological activity of trees. In addition, during a heat wave, the temperature of the trunk of a tree is lowered to increase the photosynthesis rate, and it can directly or indirectly affect trees and humans using them through far-infrared rays and negative ions. Therefore, the ocher composition according to one aspect may be for protecting trees or treating wounds or repelling pests. The pests are insects that harm trees, and include, for example, pine leaf gall flies, pine bark caterpillars, pine trees, pine species, pine broadleaf bees, pine yellow spot weevils, white pine leaf moths, pine needle moths, etc. .

In one embodiment, the composition may include 30 to 60% by weight of loess, 1 to 20% by weight of an insecticide, and water as the balance. The loess may be included in 30 to 60% by weight based on the total weight of the composition. The ocher is, for example, 30 to 60% by weight, 30 to 55% by weight, 30 to 50% by weight, 30 to 45% by weight, 30 to 40% by weight, 40 to 60% by weight, 40 to 60% by weight based on the total weight of the composition 55% by weight or 40 to 50% by weight. At this time, when the content of ocher is less than the above range, there is a problem in that the purification, sterilization or protection effect, which is a unique function of ocher, is not sufficiently exerted, and when it exceeds the above range, the drying of the ocher composition increases the powdering of the damaged area. There is a problem that coating stability is lowered.

The insecticide may be a natural or eco-friendly insecticide, and may be added to the ocher composition to maximize the insect repellent and / or bactericidal effect, which is an inherent characteristic of ocher. The insecticides are, for example, phytoncide, wood vinegar, magma Q, herbal oils (laventer, rosemary, lemon rice, lemongrass), citronella, pyrethrum, pyrethrum, ginseng, fig leaf, ginkgo leaf, oleander, astragalus, Rice porridge, tobacco leaves, cosmos, spicy pepper, bracken, rice porridge, American ball, stem, red potato, pork potato, pawpaw leaf, bark, cinnamon, horsetail, horsetail, onion, garlic, mugwort, pine needles, green tea leaves, perilla , bamboo shoots, sinwudae, balsam, eoseongcho, cypress, sorghum root, lacquer, ginkgo, dandelion, macmundong, plum, arborvitae fruit, peach tree leaves, paulownia leaves, pasqueflower, bindweed, spurge, peppermint, jarrigong, seokchangpo or extracts of mixtures thereof. The insecticide may be included in an amount of 1 to 20% by weight based on the total weight of the composition. The pesticide is, for example, 1 to 20% by weight, 1 to 18% by weight, 1 to 16% by weight, 1 to 14% by weight, 3 to 20% by weight, 5 to 18% by weight, 10 to 20% by weight or 10 to 17% by weight. At this time, if the content of the insecticide is less than the above range, there is a problem in that the insecticidal effect against pests, fungi or bacteria is not sufficiently exerted, and if it exceeds the above range, the live lactocytes of the xylem and the cambium cells under the bark of the wound edge There is a problem that damages the .

In one embodiment, the composition may further include a thickening agent. 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 10 to 35% by weight based on the total weight of the composition. The thickener is, for example, 10 to 35% by weight, 10 to 33% by weight, 10 to 30% by weight, 10 to 28% by weight, 15 to 35% by weight, 15 to 30% by weight, 20 to 35% by weight, 25 to 35% by weight or 24 to 32% by weight. At this time, when the content of the thickener is less than the above range, there is a problem that the ocher composition has low viscosity, so that it is not fixed to the damaged part of the tree and cannot be effectively protected from moisture penetration after application. There is a problem in that it is too high and it is difficult to apply it to the damaged part of the tree itself.

In one embodiment, the composition may further include a spreading agent, vegetable fiber, or a mixture thereof. The spreading agent not only provides spreadability and bonding strength of the ocher composition, but also can prevent loss of the coating film due to external environments. The spreading agent may be, for example, polyoxy ethylene alkyl arylether, sodium ligno sulfonate, flour paste, rice paste, starch powder, and 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, when the content of the spreading agent is less than the above range, there is a risk that the film applied to the damaged area may be lost due to external environments such as wind and rain due to the weak bonding force between the tree and the loess composition. If it exceeds the above range, appropriate spreadability is provided However, there is a problem in that the film is not uniformly formed on the damaged part of the tree.

The vegetable fiber is for enhancing the overall homogenization of the loess composition, for example, flax, hemp, jute, kenaf, abaca, bamboo , Coir, pineapple, ramie, sisal, henequen, hemp, rice straw, chaff, wood flour, and green tea may be prepared. The vegetable fiber may be included in 1 to 10% by weight based on the total weight of the composition. The vegetable fiber 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, when the content of vegetable fiber is less than the above range, there is a problem that not only can not sufficiently homogenize the components included in the ocher composition, but also cracking occurs after coating and curing, and when it exceeds the above range, the surface after coating and curing There is a problem that it is not smooth and may be an aesthetic hindrance factor.

Another aspect provides a method for producing a ocher composition comprising mixing ocher, an insecticide and water. Details of the loess composition are as described above.

In one embodiment, the method comprises preparing a liquid phase by mixing and stirring water, an insecticide, a spreading agent and a thickening agent; Preparing a solid phase by mixing and stirring loess and vegetable fibers; and stirring the liquid and solid phases. In the step of preparing the liquid and solid phases, a mixer, a blender, a mixer, etc. for preparing ocher putty may be used. In addition, in the step of preparing the liquid and solid phases or the step of stirring the liquid and solid phases, the mixing speed may be applied differently depending on the content and/or characteristics of the mixture within a set range.

Another aspect provides a method for protecting trees, treating wounds, or exterminating pests, which includes applying the loess composition according to one aspect to trees. Details of the loess composition are as described above. In one embodiment, the method may include applying the ocher composition to a target area of a tree and then drying it. The target site may be, for example, a withering site of a tree, a decay site, a wound site, or a damaged site. Therefore, according to the above method, it is possible to effectively protect the pruning area by preventing splitting of trees due to the effect of preventing water evaporation.

The ocher composition according to one aspect can be applied directly to the wound of a tree to treat the wound and protect the damaged area from pests, fungi, or bacteria.
