Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a composition for repairing tree wounds. More specifically, the present invention relates to a repair composition suitable for repairing tree wounds such as injection holes after injecting chemicals into 01 trees for the purpose of controlling tree pests or restoring rJf.

``Conventional technology'' For growing trees, in order to control pests such as pine borers or to restore the tree's vigor, an injection hole is drilled that acts as a wound for the tree, and a pest control agent or pest control agent is injected into the tree through this injection hole. There is a method of injecting nutrients, etc. In order to grow and care for trees, damage may be caused to the tree, such as at water spots, pruning or pruning cuts, etc.

In addition, typhoons and the like can cause trees to split, causing damage to the tree such as cracks.

If these tree wounds are not repaired, pathogenic bacteria will enter and cause the tree to rot, water and nutrients will evaporate, rainwater will accumulate, and a dead layer will form on the tree trunk, resulting in the worst case scenario. There is a risk that trees may die.

Recently, chemicals have been applied to scenic spots, gardens, precinct forests such as shrines and temples, commemorative trees, boundary forests such as forests, and relatively small numbers of plugs such as seedlings that are unlikely to die. Care and cultivation such as injection and tree wound repair are now being carried out. In order to protect the tree body and maintain its aesthetic appearance, it is necessary to repair the wounds that occur on these trees as soon as possible and restore the tree's vigor to its original level.

Conventionally, methods for repairing tree wounds include a method of inserting a piece of wood into an injection hole, and a method of applying an emulsified liquid or paste-like fungicide to the tree wound.

The method of fitting a piece of wood into a tree wound based on a chemical injection hole, etc. involves creating a faucet that matches the target hole, fitting it into the tree's injection hole, and cutting and removing the excess part.
This is a task that requires a great deal of effort and expense. As a measure against pathogen M, it is necessary to apply a disinfectant to the faucet and the injection hole in advance, which requires double effort.

A method of applying an emulsified liquid or paste-like fungicide to a tree wound can easily repair the tree wound by applying or spraying it if the wound is flat on the surface of the tree. However, it is difficult to repair deep tree wounds such as chemical injection holes or cracks. These emulsified liquid or paste fungicides usually use water as a dispersion medium, so after being applied to a tree wound, water may be absorbed or evaporated by the tree, or when exposed to wind and rain. , the retention force of the medicine is weak and it cracks, leaving it far from the 04 tree wound, causing the medicine to lose its effectiveness.

Moreover, since conventional methods for repairing tree wounds only consider protecting the tree body, many of them impair the appearance and color of the tree and seriously harm the landscape of scenic spots and the like.

[Problems to be Solved by the Invention] The present invention aims to solve the shortcomings in the conventional tree wound repair methods as described above, and the present invention uses natural vegetable oil, polybutene, a fungicide, and a filler. It is made of a coloring agent and has a penetration degree of 10 to 100 according to JIS K2207. The present invention aims to provide a highly viscous composition for repairing tree wounds.

"Means for Solving the Problems" The gist of the present invention is that (,) natural vegetable oils 5 to 3
0 parts by weight, (b) 10 to 30 parts by weight of polybutene, (e)
consisting of 0.01 to 10 parts by weight of a bactericidal agent, and (d) 50 to 80 parts by weight of a filler and/or colorant ((a) l
(b), (c) - (d) total amount is 100 parts), and the penetration is 1 in accordance with JIS K2207.
A composition for repairing tree wounds characterized by having a molecular weight in the range of 0 to 100.

The present invention will be explained in detail below.

In the present invention, natural vegetable oil refers to natural oils and fats that are obtained industrially by distillation or extraction from plant seeds or trees, etc. Natural vegetable oils are natural vegetable oils that are obtained industrially by distillation or extraction from plant seeds or tree bodies. It is used as a softening agent in compositions, as well as imparting biocompatibility to the skin and enhancing the wound repair effect.

The natural vegetable oil, as a component of the composition for repairing tree wounds, must be 5 to 30 parts by weight based on the entire composition according to the present invention. If the amount is less than 5 ml parts, the biocompatibility between the composition and the tree will be poor, and the fluid part of the composition will decrease, making the composition hard and brittle, which is not preferable.

If the amount exceeds 30 parts (1 part), the composition according to the present invention becomes too soft, and natural vegetable oil from the #fI composition in the wound area of the tree is absorbed into the tree body or transpires over time, causing the composition and the wound area to This is not preferable because it tends to cause gaps and cracks in the darkness of the area.

Specific examples of natural vegetable oils include soybean oil, rapeseed oil, sesame oil, cottonseed oil, chickpea oil, linseed oil, coconut oil, pine oil, turpentine oil, and camphor. These natural vegetable oils may be one type or a mixture of two or more types, depending on the type of target tree and the condition of the wound.
They can be selected and combined as appropriate.

In the present invention, polybutene is a known butene polymer in the form of a viscous liquid or wax.

Polybutene imparts toughness, 71 ductility and flexibility to the composition according to the present invention. Polybutene is used as a blended component of the composition in a proportion of 1% to the total composition according to the present invention.
It should be between 0 and 30 parts by weight. If the content of polybutene is less than 10 parts by weight, the toughness, spreadability and flexibility of the composition will decrease, which is undesirable. If it exceeds 30 parts by weight, the acid product of 1 will become too soft and This is not preferable since there is a risk that the composition may be expelled from the tree due to leaching pressure from the tree.

The types and amounts of polybutenes can be appropriately selected and combined within a predetermined range depending on the purpose of the composition for repairing tree wounds of the present invention.

The fungicide in the present invention has the effect of killing fungi that parasitize trees and cause diseases, and fungi that invade through tree wounds and rot trees.
A chemical that does not cause chemical damage to trees, such as discoloration or death of leaves and tree bodies.

When the fungicide is used as a tree wound repair composition,
It acts to prevent the invasion and breeding of grasshoppers and insects that cause pest damage to tree wounds, and to support the normal growth of trees.

As a component of the composition according to the present invention, the bactericide must be present in an amount of 0.01 to 10 parts by weight based on the entire composition; if the content of the bactericide is less than 0.01 parts by weight, it will not be sterilized. It loses its medicinal effect as an agent and loses its effectiveness in controlling trees from pests and diseases and repairing tree wounds. If the amount exceeds 10 parts by weight, it is not preferable because phytotoxicity is likely to occur and the cost of the fungicide in the composition increases.

Specific examples of fungicides include methyl 100phanate, guazatine, TBZ, PCMX, ambam, triazine, benomyl, plastocynon S1 guyfortan, cabtan, chloroneb, DBED01 dimethylimole, notia/one, 7-fluorimide, IBP, iprodione, maneb. , oxyfluvoxin, polyoxin, procymidone, thiuram, triforine, vinclocillin, and zineb.

These are one type or a mixture of 2+1 or more,
Solid, liquid, paste, and emulsified liquid forms are commonly used.

The filler and/or coloring agent in the present invention has the effect of filling and covering a tree wound in a composition for repairing tree wounds, and of covering the tree wound inconspicuously with the colored r-composition. The filler and V/or coloring agent have little pharmacological effect on trees (preferably, they are water-insoluble).

Specific examples of fillers include inorganic fillers such as calcium carbonate, clay, talc, white carbon, humid silica, barium sulfate, zinc white, asbestos, Rockrule, glass fiber, wollastonite, and mica, wood powder, valves, Examples include organic fillers such as organic fillers.

Specific examples of colorants include pigments such as titanium oxide, molybdenum white, copper 7 thalocyanine, carbon black, and dyes such as oil brown. These fillers and/or colorants may be used alone or in a mixture of two or more.

Fillers and pigment-based colorants can be used together with appropriate surface treatment agents or dispersants such as metal soaps, if necessary, to increase the dispersibility and miscibility of the composition according to the present invention. The composition can be colored in any desired color tone by appropriately combining dyes and pigments according to the target tree's epidermis or branches and leaves. The filler can adjust the viscosity of the composition according to the present invention, and if necessary, a surface treatment agent, a dispersant, or a thickener for the filler can be appropriately combined to form a plastic fluid having an anti-sag effect. It can be done.

The filler and/or colorant must be used as a component of the composition according to the present invention in an amount of 50 to 80 parts by weight based on the total composition. If it is less than 11 parts, the composition becomes too soft and fluid, which is undesirable. If it exceeds 80 parts by weight, the toughness, ductility, and flexibility of the composition decrease, and it becomes hard.

The blending ratio of each component contained in the tree wound repair composition according to the present invention is as follows: (,) natural vegetable oil, (b) polybutene, (e) fungicide, and (d) filler and/or colorant. Each component must be selected and combined so that the total amount of is 100 parts by weight.

The composition for repairing tree wounds according to the present invention conforms to JISK2220
The penetration must be in the range of 10 to 100 according to 7.

In the present invention, penetration refers to JIS K2207-1
980, the length that a specified needle vertically enters a sample at 25°C for 5 seconds, expressed in units of 0.11.
If the penetration degree of the composition is less than 10, the composition is hard and the inside of the tree wound cannot be sufficiently filled and covered with the composition, leaving voids and the tree wound cannot be repaired properly. If the penetration degree exceeds 100, the composition has good fluidity and cannot maintain a constant shape, making it impossible to fill and cover tree wounds until complete healing.
In this case, there is a risk that the composition may be pushed out of the tree wound due to the leaching pressure of the sap, or the repaired composition may be washed away by rainwater or the like, which is not preferable.

The composition for repairing tree wounds according to the present invention can be produced by mixing and kneading the above-mentioned natural vegetable oil, polybutene, fungicide, and filler/coloring agent by a known method.For example, A crusher, a muller mixer, a mixing roll, a two-screw continuous mixer, an extrusion rock type mixed wire rock, etc. can be used.

The composition for repairing tree wounds according to the present invention can be used to fill and cover tree wounds such as injection holes for chemicals for exterminating pine borers.
Used to fix fi.
