Abstract

PROBLEM TO BE SOLVED: To prevent the generation of environmental pollutants as much as possible by the use of a raw material of an organic substance using a natural material and, simultaneously, to improve the mixing property of glue with other components to render handling easy. SOLUTION: A coating using a natural material such as a coating material, a coating primer, and an adhesive, which comprise glue as an organic substance and are coated on a material to be coated, such as wood, contains pyroligneous acid. The acetic acid component of this pyroligneous acid acts on the glue to enable the glue to retain in a liquid state even at normal temperatures. Consequently, a uniformly mixed state of the glue with other compositions can be obtained to dissolve the complicatedness of handling due to viscosity, and since the coating is of a raw material of an organic substance using a natural material together with glue and pyroligneous acid, even by using or dumping it or the like, environmental pollution such as air pollution and soil pollution is inhibited. For example, a coating which functions as a coating material comprises 60-80 wt.% astringent persimmon fluid, 10-15 wt.% glue, and 5-15 wt.% purified pyroligneous acid having a pH of 34.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coating material using a natural material which is effective mainly as a coating material for wood products, and to a coating material using a natural material which functions as a paint, a paint base material, an adhesive, and the like. About.

[0002]

2. Description of the Related Art In general, coating agents for wood products and the like include:
There are various paints, paint base materials, adhesives, etc. In recent years, environmental pollution such as air pollution and soil pollution has been caused by using or discarding these paints, paint base materials, adhesives, etc. This causes various allergic reactions to the human body and cell deformity. Therefore, it is desired to produce the raw materials using pollution-free raw materials as much as possible. In order to solve this, the applicant of the present application has conducted research and development in which organic materials using natural materials are used in place of raw materials for chemical synthesis, and the cause of these contaminations is minimized. We have been conducting trial and error research on coating materials using natural materials composed of glue as an organic substance.

[0003]

By the way, glue is used in the coating agent which has been studied, but glue is not used with other compositions unless the viscosity is reduced by baking water or the like. Since troubles such as the inability to obtain a uniform mixed state occur, there has been a problem that handling is complicated. The present invention has been made in view of such problems, and uses an organic raw material made of a natural material to minimize the generation of environmental pollutants, and to improve the compatibility between glue and other components. It is an object of the present invention to provide a coating material using a natural material which has been improved in ease of handling.

[0004]

The technical means of the present invention for solving the above-mentioned problems is to apply a natural material which is constituted by containing glue as an organic substance and is applied to a material to be applied such as wood. The composition contains a wood vinegar solution. The glue is a general term for low-quality gelatin containing impurities, and generally refers to animal glue made from animal skin and bone. When water is added, it becomes a colloid and dissolves. When heated, it becomes a sol, and when cooled again, it becomes a gel. Wood vinegar is a liquid obtained by carbonizing wood, and contains acetic acid as a main component. The acetic acid component of the wood vinegar acts on the glue so that the glue can be kept in a liquid state even at room temperature. For this reason, a uniform mixed state with other compositions can be obtained, and the complexity of handling due to viscosity is eliminated, and both glue and wood vinegar are raw materials of organic substances using natural materials, and by using them, Or
Disposal and the like suppresses environmental pollution such as air pollution and soil pollution.

[0005] As a coating agent using a natural material having such a configuration, the present applicant has proposed the following three types (A), (B) and (C).
A variety of coatings have been developed. (A) Coating agent using natural material functioning as paint This is a coating agent using a natural material which is composed of a main material of coating material and glue as an organic material and is applied to a material to be coated such as wood to function as a coating material. , The composition contains 5 to 15% by weight of a purified wood vinegar solution having a pH of 3 to 4. Desirably, the purified wood vinegar is contained in an amount of 6 to 9% by weight. If it is less than 5% by weight, the viscosity of the glue cannot be sufficiently reduced, and if it exceeds 15% by weight, it will be too fluid. The purified wood vinegar solution is obtained by adjusting the components of the stock solution by vacuum distillation or the like and adjusting the pH to 3-4.

[0006] If necessary, a persimmon juice liquid is used as the paint main material. Persimmon juice is 60 ~
It is desirable to have 80% by weight. Generally, persimmon juice is
It is a dark brown liquid obtained by squeezing blue immature astringent persimmon, fermenting, and aging for 2-3 years. Persimmon astringent contains high molecular weight tannin as a main component and has a unique smell like ginkgo, but it comes off when dried and gradually becomes darker in sunlight. In addition, it has not only a paint function but also insect repellent, waterproof, antiseptic and antibacterial effects. If necessary, the glue is added in an amount of 10 to 15% by weight.
Configuration.

[0007] With such a configuration, in the case of a coating agent which functions as a coating material, the coating surface strength and the protective effect are enhanced when used, and the curing and drying speed of the surface is increased. This is considered to be due to the fact that the chondroitin component of glue will be evenly distributed by mixing a mixture of persimmon juice and wood vinegar, and the curing speed will be further accelerated. In addition, by mixing wood vinegar with persimmon juice, the waterproof effect of persimmon juice is enhanced,
Further, it is considered that there is an interaction for improving the uniformity on the application surface.

[0008] If necessary, hiba oil is added in an amount of 10% by weight or less. Also, if necessary,
The composition is such that 0% by weight or less of wasabi oil is added. Generally, hiba oil is also called hinoki oil, and is extracted by treating sawdust such as hiba wood by a steam distillation method or the like. The component is a mixture of a neutral oil such as Tuyobsen and about 10% of an acidic oil such as hinokitiol. Components such as hinokitiol exhibit extremely strong antibacterial activity. Also,
Generally, wasabi oil is composed of an essential oil component containing terpenes and ketones extracted from the rhizome of wasabi (wasabi).
A glycoside called sinigrin and an enzyme called myrosinase, which degrades it, release volatile essential oils when water is added, generate a unique fragrance, and have a very strong antiseptic and bactericidal action. With this configuration, functions such as sterilization, antibacterial action, and antifungal action are exhibited, and in addition, an action of exerting a strengthening action of the surface film is also considered, so that the function as a paint may be expanded.

(B) Coating agent using a natural material functioning as a coating base material This coating material has abrasive powder and contains organic glue as an organic substance, and is applied to a coating material such as wood to function as a coating base material. PH of natural materials
= 3-4 purified wood vinegar is contained in an amount of 15-25% by weight. Desirably, the purified wood vinegar solution is 20 to 22
% By weight. If it is less than 15% by weight, the viscosity of the glue cannot be sufficiently reduced, and if it exceeds 25% by weight, it will be too fluid. And it is set as the structure which contains the said abrasive powder 30-40 weight% as needed. In addition, if necessary, the composition is configured to have the above-mentioned glue in an amount of 15 to 30% by weight.

With this configuration, the paint base material has the greatest purpose of eliminating irregularities on the coated surface of a workpiece such as wood before coating, but the paint base material which has a function of removing irregularities has been conventionally used. Greatly improved compared to. In other words, the conventional method uses "water" to make the abrasive powder muddy, and with the passage of time, the abrasive powder and water are completely separated, but by adding wood vinegar to the abrasive powder, they are uniformly mixed and separated. Nothing. This is considered to be due to the action of liberating the phenols contained in the wood vinegar in a trace amount, and to be completely and uniformly mixed in a mud-like manner and to be sustained. As a result, it is easy to uniformly enter the unevenness, and the unevenness eliminating function is improved.

Further, if necessary, a powdery sticky rice is added. It is desirable to add 10 to 30% by weight of glutinous rice. As a result, glue rice is added in addition to glue, so glutinous rice is softer than abrasive powder, so that these easily penetrate into the uneven portions of the material to be coated, the adhesion effect and the hardening effect are enhanced, and the uneven surface is improved. The rejection ability is improved, and the coating surface can be made uniform. Furthermore, if necessary, 2 wt% or less of hiba oil is added. In addition to the effects of disinfecting, antibacterial, and antifungal, the effect of strengthening the surface film is also considered, and the underlying function may be expanded.

(C) Natural material functioning as an adhesive This is a coating agent using a natural material which is composed of organic substances containing not less than 60% glue and is applied to a material to be coated such as wood to function as an adhesive. In the above, the purified wood vinegar having a pH of 3 to 4 is contained in an amount of 5 to 10% by weight. Preferably, the purified wood vinegar solution is contained in an amount of 7 to 8% by weight. If the amount is less than 5% by weight, the viscosity of the glue cannot be sufficiently reduced, and if it exceeds 10% by weight, the glue is excessively fluidized. With this configuration, the primary purpose of the adhesive, when used for a material to be coated such as wood, is to make use of the fact that the applied surface is uneven before coating, so that the greatest purpose is to infiltrate the raw material and cure the adhesive. However, since the wood vinegar liquid is mixed, the glue becomes liquid, and therefore, the curing strength of the bonding surface and the infiltration rate to the uneven portion are further enhanced, and the permeability is made uniform. In addition, with conventional petrochemical adhesives, a chemical dissolving agent is added for curing and a dissolved state is secured with volatile substances. Substances often evaporate, and there is a concern that excretion of environmental hormones and the like, which are considered harmful to the human body, may occur.However, this adhesive developed in the present invention uses a natural material as a raw material. Therefore, environmental pollution and excretion of environmental hormones are suppressed.

[0013] If necessary, powdery glutinous rice is added. It is desirable to add 15 to 30% by weight of glutinous rice. As a result, glue rice is added in addition to glue, so that the curing strength of the adhesive surface and the infiltration rate with respect to the uneven portion are further enhanced, and the effect of making the permeability uniform is improved. In addition, the composition is such that 2% by weight or less of hiba oil is added as required. Further, if necessary, 2 wt% or less of wasabi oil is added. With this configuration, functions such as sterilization, antibacterial action, and antifungal action are exhibited, and in addition, an action of exerting an action of strengthening adhesion is also considered, and the function as an adhesive is considered to be expanded.
