Boron-containing borate and boron compounds (hereinafter referred to as boric acid), boric acid-containing coating solvents that fix and fix the boric acid concentration on building materials, and building materials The present invention relates to a boric acid-containing adhesive solvent to be adhered, and a treatment method for adhering and fixing boric acid powder and boric acid-containing substances.

The boric acid treatment performed for the purpose of preserving, preventing and preventing insects of general building materials (hereinafter referred to as building materials) is to mix boric acid with water or a highly hydrophilic solvent, and the boric acid concentration is about 10% by mass. Alternatively, a boric acid aqueous solution having a higher concentration is prepared, and a pressure injection treatment method in which this is pressurized and injected at a pressure treatment facility in a factory, an immersion treatment method in which a liquid tank is submerged, and the like. However, products such as wiring of buildings and machinery and equipment installed in buildings, piping products and other installation parts (hereinafter referred to as products) are hoses intended for antiseptic, ant-proofing and insect-proofing purposes. There was no acid treatment method.

At construction sites under construction, boric acid is mixed with water or a highly hydrophilic solvent to create a boric acid aqueous solution having a boric acid concentration of about 10% by mass or higher, and building materials before assembly or during assembly. A method of applying and spraying directly on the surface and then naturally drying is employed.

Further, as a treatment method for a building such as a house in use, a boric acid aqueous solution having a concentration of about 10% by mass or higher is directly applied and sprayed to a portion where it may get wet with water, In areas where it should not get wet, boric acid is not dissolved in water, but in a powdered state, it is sprayed using wind power (dusting).

For example, Patent Document 1 discloses that in an aqueous solution containing a polyvinyl alcohol resin as a main component, 2 to 30 parts by weight of a boron compound with respect to 100 parts by weight of a polyvinyl alcohol resin, and all boron of the boron compound is boric acid. Insect repellent comprising a boron compound-containing polyvinyl resin aqueous solution containing at least one sugar alcohol among glycerin, diglycerin, mannitol, and xylitol in an amount equal to or greater than the number of molecules of boric acid. An adhesive is disclosed.

In addition, Patent Document 2 has antifungal and antibacterial properties, and is used for inorganic materials such as indoor and outdoor plastic materials, paper materials, wood materials, fiber materials, metal materials, concrete materials, and the like. A resin emulsion having a film-forming ability that is emulsion-polymerized using an agent, a boric acid compound, and a zinc compound. One water-based coating agent has been proposed.

A wood surface treatment agent that uses borate as an active ingredient to prevent decay and insect damage has been proposed (see Patent Document 4). For example, a composition in which 25% or more borate in terms of boron oxide (B ₂ O ₃ ) is dissolved in ethylene glycol has excellent performance as a wood preservative (see Patent Document 5). Further, a composition comprising 4 to 23% polyalkylene glycol, 20 to 50% alkylene glycol and glycol-soluble borate is said to be excellent as a wood preservative (see Patent Document 6). These compositions are applied or spread on the wood surface as they are or after adding water to adjust the boron concentration and the solution viscosity.

In particular, Patent Document 7 discloses that wood is treated with a silicon emulsion composition having a film-forming ability, a boron-based compound, and sulfate, so that the water repellency and water absorption resistance of the wood are maintained without changing the appearance and performance of the wood. Wood treatment methods that can improve dimensional stability, ant-repellent properties, and antibacterial properties have been proposed. Similarly, high-molecular-weight insecticides, insecticides, and antiseptic treatment methods in which an inorganic polymer coating is formed on woody materials. The main component is a sodium silicate solution A that forms a film, and this A solution is mixed with B solution consisting of a mixture of alum solution and boric acid solution, and cypress wood, hiba material, etc. are mixed into this mixed AB solution. A solution in which the solution C of the tropolone solution extracted from the mixture is mixed to obtain an ABC complex solution has been proposed (see Patent Document 8).

As described above, use of boric acid as a preservative, anti-ant, and insect repellent for building materials makes a boric acid aqueous solution, and performs surface treatment by pressure injection treatment, water immersion treatment, application, and spraying with the boric acid aqueous solution. This is the current situation. In other words, in order to treat with boric acid, there are many methods in which boric acid is dissolved in a large amount of water or a highly hydrophilic solvent and used. It is limited to foundation building materials, etc., and it should not be wet with water, and it is shaped by moisture, such as dry materials, decorative materials, finishing materials, plywood, paper, dried plants such as rush, rattan, rice straw, bamboo, etc. Because it has water repellency and waterproof properties such as changing building materials and products, polyurethane, rubber, plastic, aluminum, metal, etc., it was unsuitable for building materials and products that cannot contain water from the surface. .

In addition, the method of dusting in the form of powder without dissolving boric acid in water (dusting) can be used in places that cannot be wet with water such as the interior of walls and the back of ceilings of existing buildings. In many cases, it is an unstable treatment method that may move and peel and scatter due to gap air, vibration, static electricity, temperature difference, etc. after spraying. In particular, this processing method is inappropriate for objects that move or move from the beginning. Furthermore, with this treatment method, boric acid sprayed (dusted) inside the building may fall, scatter, and scatter naturally into the living space from the gaps in the building due to vibrations and drafts. In addition, there is a risk of falling, scattering, or scattering around the building when it is demolished, refurbished, or repaired.

It is an object of the present invention to provide a method for adhering and fixing a solvent, a boric acid-containing adhesive solvent, boric acid powder, and a boric acid-containing material.

That is, since most of the conventional boric acid treatments use a large amount of water, it was not possible to treat building materials and products that cannot be wetted with water, and building materials and products that cannot allow water to adhere to the surface. In addition, since the dispersion in the powder state is unstable adhesion, building materials and products that cannot be wetted with water cannot be transported and shipped by boric acid treatment at a factory or the like in advance.

Therefore, the boric acid-containing coating solvent of the present invention is prepared by directly mixing boric acid in powder form with a solvent having a coating performance such as an adhesive, glue, paint, water repellent, waterproofing agent, etc. Covering with a boric acid-containing coating is the first gist. In addition, it is important to mix an aqueous solution with a high boric acid concentration with an aqueous solvent having a coating performance such as adhesive, paste, paint, water repellent, waterproofing agent, etc., and cover the surface of the material to be treated with a boric acid-containing film. The gist of 2. Furthermore, the third gist is to fix boric acid powder to an adhesive surface treated with a coating solvent containing boric acid or a coating solvent not containing boric acid. It is a fourth gist to apply a boric acid-containing material such as a boric acid-impregnated sheet such as cloth or paper that can be impregnated with an acid and dried. Furthermore, the fifth gist is to bond building materials, products, cloth, wallpaper, etc. with an adhesive or glue having a high boric acid concentration.

Preservatives, Boarizai, boric acid as an insect repellent is an inorganic compound containing boron, disodium octaborate tetrahydrate _{(Na 2 B 8 O 13 ·} 4H 2 O: DOT) is easily soluble in water It is often used for pressure injection and surface treatment of wood.

The coating performance and adhesion performance as used in the present invention are a fixable substance, a solvent that can cover the surface of a target material with a film, and a commonly used paint, water repellent, waterproofing agent. These are components such as adhesives and glues, which are hydrophilic and can be mixed with a high concentration aqueous boric acid solution.

Water-soluble adhesives and glue components are naturally derived from starch, rubber, lacquer, pine and other natural resin systems, animal protein systems such as gelatin-rich glues, and other acrylic and polyvinyl alcohol systems. And synthetic resin systems of chemical synthesis components such as vinyl acetate. Also, in paints, boric acid is mixed directly with hydrophilic components such as water-based paints, water-based urethane, water-based urethane, and water-based silicone, which is a component of paints and water repellents. It can also be used. In addition, water-soluble component solvents with coating performance include water-based acrylic, water-based vinyl urethane, water-based epoxy resin, water-based silicon, etc., and boric acid powder can be mixed directly with these or boric acid aqueous solution can be mixed. it can.

In the present invention, when considering mixing boric acid powder directly with a component having coating performance or adhesive performance or mixing with a high concentration boric acid aqueous solution, polyvinyl alcohol is used for making slime. It causes a problem in force, and since vinyl acetate is an acetylated polyvinyl alcohol, it does not mix with boric acid. Further, since boric acid to be used is neutral to weakly alkaline (pH 7 to 8 in an aqueous solution), it is better to avoid mixing with a solvent containing a strong acid, strong alkali or the like.

These ingredients that can be mixed with boric acid powder or high-concentration boric acid aqueous solution are naturally derived from starch, natural resin ingredients, animal proteins, and other chemical synthetic ingredients that are relatively easy to use. Water-based acrylic, water-based urethane, and water-based silicon are preferable. Non-aqueous solvent-based paints include oil-based paints, lacquers, alcoholic paints, and the like, and boric acid powder can be directly added to these. Many of these solvent-based paints are diluted with an organic solvent thinner. This organic solvent thinner is prepared by blending toluene and xylene. Toluene and xylene are heated and circulated to remove boric acid. It can be dissolved and mixed, and can be used as a boric acid-containing solvent for diluting paints other than water. However, it is desirable to adopt it with due consideration of cost, environment, health, workability, and the like.
