Abstract
Description
本発明は、主に建築物に用いられる木質材料に対する下地処理方法と、この下地処理方法に用いられる下地処理剤と、前記下地処理方法が施された木質材料とに関する。 The present invention relates to a ground treatment method for a wood material mainly used for buildings, a ground treatment agent used in the ground treatment method, and a wood material subjected to the ground treatment method.
木質材料の燃えやすいという性質は、木質材料を使う側にとって大きな欠点の一つである。そこで、加圧注入等の方法により、ホウ酸系やリン酸系の水溶性薬剤を木質材料の内部にまで含浸させ、木質材料の不燃化、準不燃化又は難燃化を図っている。木質材料の不燃化を図る方法だけであっても、例えば、特開２００５−１８６６２０、特開２００５−１９４３１９、特開２００３−２１１４１２や特開２００３−２９１１１０等がある。 The flammable nature of wood materials is one of the major drawbacks for those using wood materials. Therefore, a boric acid-based or phosphoric acid-based water-soluble drug is impregnated into the wood material by a method such as pressure injection to make the wood material incombustible, semi-incombustible or flame-retardant. Even if only the method for making the woody material incombustible is used, for example, there are JP-A-2005-186620, JP-A-2005-194319, JP-A-2003-211412, and JP-A-2003-291110.
特開２００５−１８６６２０や特開２００５−１９４３１９では、ホウ酸系薬剤とリン酸系の併用によって木質材料の不燃化を図り、特開２００３−２１１４１２や特開２００３−２９１１１０では、ホウ酸系薬剤により木質材料の不燃化を達成している。 In JP-A-2005-186620 and JP-A-2005-194319, wood materials are made incombustible by the combined use of boric acid-based chemicals and phosphoric acid-based materials. In JP-A-2003-211412 and JP-A-2003-291110, boric acid-based chemicals are used. Incombustibility of wood materials has been achieved.
また、国土交通省が認定した不燃化された木質材料としては、ホウ酸系とリン酸系薬剤による不燃木質材料の登録がそれぞれ数件ずつある。このように、含浸による木質材料の不燃化を図る水溶性薬剤には、ホウ酸系薬剤かリン酸系薬剤の少なくとも一方が含まれている。 In addition, as the incombustible wood materials approved by the Ministry of Land, Infrastructure, Transport and Tourism, there are several cases of registration of incombustible wood materials with boric acid and phosphoric acid chemicals. Thus, the water-soluble chemical | medical agent which aims at the incombustibility of the wood material by an impregnation contains at least one of a boric acid type | system | group chemical | medical agent or a phosphoric acid type chemical | medical agent.
ところで、これらのホウ酸系薬剤やリン酸系薬剤は、高い吸湿性を持つことが知られており、そのままの状態で木質材料に含浸させると、大気中の水分を吸収し、不燃、準不燃又は難燃処理をした木質材料から薬剤が自然に滲み出して、性能や美観を著しく低下させてしまうという欠点がある。そこで、これらの不燃化された木質材料は、塗装等を施して、性能、美感の低下の防止を図ることが不可欠となる。 By the way, these boric acid-based chemicals and phosphoric acid-based chemicals are known to have high hygroscopicity, and when impregnated into a wood material as they are, they absorb moisture in the atmosphere, and are incombustible and semi-incombustible. Or there exists a fault that a chemical | medical agent oozes naturally from the woody material which carried out the flame-retardant process, and a performance and aesthetics are reduced remarkably. Therefore, it is indispensable that these incombustible wood materials are coated to prevent deterioration in performance and aesthetics.
しかしながら、上述した特開２００５−１８６６２０、特開２００５−１９４３１９、特開２００３−２１１４１２や特開２００３−２９１１１０等は、木質材料の不燃、準不燃又は難燃処理のみが考慮されていて、塗装については特に考慮されていない。 However, JP 2005-186620 A, JP 2005-194319 A, JP 2003-211412 A, JP 2003-291110 A, etc. described above consider only incombustibility, quasi-incombustibility, or flame retardant treatment of a wood material. Is not specifically considered.
また、木質材料では、藻や苔がつくことを防止する防藻性、シロアリを防ぐ防蟻性、防腐性も要求される性能である。
塗装に用いる塗料は、一般的に浸透型と造膜型とに分けることができる。さらに別の分類では、溶剤型塗料と水性塗料と分類することができる。まず、浸透型塗料は現在溶剤型塗料が主である。この浸透型塗料の不燃、準不燃又は難燃処理木質材料への塗装は可能であるが、大気からの吸湿を防ぐことがほとんどできず、不燃化のための薬剤は塗装面から滲み出してしまうという問題点がある。 The paint used for painting can generally be divided into a permeation type and a film-forming type. In yet another classification, solvent-based paints and water-based paints can be classified. First of all, penetration type paints are mainly solvent type paints. This penetrating paint can be applied to incombustible, semi-incombustible or flame-retardant treated wood materials, but it can hardly prevent moisture absorption from the atmosphere, and the incombustible chemical will ooze out from the painted surface. There is a problem.
一方、造膜型塗料でも、溶剤型塗料での塗装は可能であるが、近年環境への配慮から、脱溶剤化が進み、水性塗料に移行しているのが現状である。また、造膜型塗料と、不燃、準不燃又は難燃処理木質材料との間には、付着性に若干の問題があるためか、溶剤型塗料でも使用環境によっては薬剤の吹き出しが生じる。 On the other hand, although film-forming paints can be applied with solvent-based paints, in recent years, due to environmental considerations, solvent removal has progressed and water-based paints have shifted to water-based paints. In addition, there is a slight problem in adhesion between the film-forming paint and the incombustible, semi-incombustible, or flame-retardant treated wood material, and even a solvent-type paint may cause a chemical to blow out depending on the use environment.
水性塗料では助剤を用いて塗膜成分を水に分散させているが、浸透型、造膜型のいずれの場合も、アルカリ側で安定化している。それを不燃、準不燃又は難燃処理木質材料に塗布すると、リン酸やホウ酸を主とする不燃化のための薬剤が塗料中に滲み出して、塗布直後にゲル化してしまうため、均一な塗膜を形成することができない。その理由としては、塗料のｐＨ変化、電荷の変化、あるいは化学的な変化などが考えられる。仮に塗装を行ったとしても、付着性に問題があり、確実に塗膜の剥離や亀裂が発生して、その部位から薬剤が吹き出し、それが大きな問題となっている。 In water-based paints, an auxiliary agent is used to disperse the coating film components in water, but both the permeation type and the film-forming type are stabilized on the alkali side. When it is applied to non-combustible, semi-incombustible or flame-retardant treated woody materials, the non-combustible chemicals, mainly phosphoric acid and boric acid, ooze out into the paint and gel immediately after application. A coating film cannot be formed. The reason may be a change in pH of the paint, a change in charge, or a chemical change. Even if the coating is performed, there is a problem in adhesion, and the peeling or cracking of the coating film is surely generated, and the drug blows out from the site, which is a big problem.
例えば、水酸化ナトリウムや炭酸ナトリウム、アンモニアなどのアルカリ性の水溶液に浸漬や、それらの塗布などを行い、ホウ酸系およびリン酸系の水溶性薬剤により不燃、準不燃又は難燃処理をした木質材料の表面を中和、あるいはアルカリ側にシフトさせた後、水性塗料を塗布しても、水性塗料のゲル化を防ぐことはできなかった。このことから不燃、準不燃又は難燃処理をした木質材料表面のｐＨを上げて、塗布直後に起こる水性塗料のｐＨの低下を抑えるだけでは、前記水性塗料のゲル化を防ぐことは不十分であることが判明した。 For example, wood materials that have been immersed in an alkaline aqueous solution such as sodium hydroxide, sodium carbonate, ammonia, etc., applied, and treated with non-combustible, semi-incombustible or flame-retardant treatment with boric acid and phosphoric acid water-soluble chemicals Even if the aqueous coating material was applied after neutralizing or shifting the surface to the alkali side, gelation of the aqueous coating material could not be prevented. For this reason, it is not sufficient to prevent gelation of the water-based paint simply by increasing the pH of the surface of the wood material that has been subjected to incombustible, semi-incombustible or flame-retardant treatment, and suppressing the decrease in the pH of the water-based paint that occurs immediately after application. It turned out to be.
本発明は、上記の問題点の解決を意図したものである。すなわち、本発明の主たる目的は、ホウ酸系およびリン酸系の水溶性薬剤を用いて不燃、準不燃あるいは難燃処理をした木質材料に対して、水性塗料の均一な塗布を可能にする方法を提供することである。さらには、処理木質材料と水性塗料との付着性を高め、使用時に剥離や亀裂が発生しにくく薬剤の吹き出しを抑制できる方法を提供することである。 The present invention is intended to solve the above problems. That is, the main object of the present invention is to provide a method for uniformly applying a water-based paint to a wood material that has been subjected to incombustible, semi-incombustible or flame-retardant treatment using boric acid and phosphoric acid water-soluble chemicals. Is to provide. It is another object of the present invention to provide a method capable of improving the adhesion between the treated wood material and the water-based paint, preventing the peeling and cracking during use, and suppressing the blowing of the medicine.

Soaked or impregnated.
さらに、本発明に係る木質材料は、リン酸系又はホウ酸系の水溶液により不燃、準不燃又は難燃性処理を行われた木質材料であって、アルカリ土金属、チタン、マンガン、鉄、コバルト、ニッケル、銅、銀、亜鉛又はアルミニウムの塩、酸化物、水酸化物又は錯体のうち少なくとも１つ以上が溶解された溶液が、塗布、浸漬又は含浸されている。 Further, the wood material according to the present invention is a wood material which has been subjected to non-combustion, semi-incombustibility or flame-retardant treatment with a phosphoric acid-based or boric acid-based aqueous solution, and is an alkaline earth metal, titanium, manganese, iron, cobalt A solution in which at least one of a salt, oxide, hydroxide or complex of nickel, copper, silver, zinc or aluminum is dissolved is applied, dipped or impregnated.
本発明に係る木質材料の下地処理方法を用いると、リン酸系あるいはホウ酸系の水溶性薬剤により不燃、準不燃あるいは難燃性を付与した木質材料からの薬剤の滲み出しを抑制すること、さらには防藻性、防腐性、防蟻性を高めることができる。また、塗料の主流となりつつある水性塗料が適応可能になる。これらのことにより、耐久性に優れた不燃、準不燃あるいは難燃性を付与した木質材料を提供することができる。その結果として、耐候性が付与され、屋外での使用も可能になる。また、着色等により意匠性を付与することが可能になるという効果がある。 Using the wood material ground treatment method according to the present invention, suppressing the exudation of the drug from the wooden material imparted incombustibility, quasi-incombustibility or flame retardancy with a phosphoric acid or boric acid water-soluble chemical, Furthermore, it can enhance the algae, antiseptic and ant-proof properties. In addition, water-based paints that are becoming the mainstream of paints can be applied. By these things, the wooden material which provided the incombustible, semi-incombustible, or flame retardance excellent in durability can be provided. As a result, weather resistance is imparted and it can be used outdoors. Moreover, there exists an effect that it becomes possible to provide designability by coloring etc.
かかるリン酸系あるいはホウ酸系薬剤の滲み出し抑制効果は、アルカリ土金属、ジルコニウム、チタン、マンガン、鉄、コバルト、ニッケル、銅、銀、亜鉛又はアルミニウムの塩、酸化物、水酸化物又は錯体のうち少なくとも１つ以上が溶解された溶液を、塗布、浸漬又は含浸することで、ホウ酸系およびリン酸系の水溶性薬剤を不溶化、あるいは難溶化し、水性塗料への滲み出しを防ぐことや、水性塗料のｐＨ変化を抑制することに起因している。 The effect of suppressing the seepage of such a phosphoric acid or boric acid agent is an alkaline earth metal, zirconium, titanium, manganese, iron, cobalt, nickel, copper, silver, zinc or aluminum salt, oxide, hydroxide or complex. By applying, dipping, or impregnating a solution in which at least one of them is dissolved, the boric acid and phosphoric acid-based water-soluble drugs are insolubilized or hardly soluble to prevent exudation to water-based paints. Further, this is due to the suppression of the pH change of the water-based paint.
さらには、本発明に係る木質材料の下地処理方法が施された木質材料は、藻や苔がつくことを防止する防藻性、シロアリを防ぐ防蟻性、防腐性が高まることも実験で確認されているが、かかる防藻性、防腐性、防蟻性を付与する効果は、リン酸系あるいはホウ酸系薬剤により不燃、準不燃あるいは難燃化した木質材料に対して、不溶化、あるいは難溶化されたホウ酸化合物やリン酸化合物が、藻、腐朽菌、シロアリ等の木質材料を劣化させる主たる生物に対して、高い抵抗性をもっていることに起因するものである。 Furthermore, it has also been confirmed through experiments that the wood material subjected to the ground material treatment method according to the present invention has improved alga-proof properties that prevent algae and moss from sticking, termite-proof properties that prevent termites, and antiseptic properties. However, the effect of imparting such algae, antiseptic and ant-proofing properties is insolubilized or difficult to make wood materials incombustible, semi-incombustible or incombustible with phosphoric acid or boric acid chemicals. This is because the solubilized boric acid compound and phosphoric acid compound have high resistance to main organisms that degrade woody materials such as algae, rot fungi, and termites.
また、炭酸ジルコニウムアンモニウムにあっては、リン酸系あるいはホウ酸系の不燃薬剤の存在なしでも、処理後の乾燥過程で形成する水に不溶の酸化ジルコニウムが、藻、腐朽菌、シロアリ等の木質材料を劣化させる主たる生物に対して、高い抵抗性をもっていることに起因するものである。従って、炭酸ジルコニウムアンモニウムが溶解された溶液の塗布、浸漬又は含浸による処理で、藻、腐朽菌、シロアリ等の木質材料を劣化させる生物に対する抵抗性を付与するためには、リン酸系あるいはホウ酸系の不燃薬剤の存在は問われない。 In addition, in ammonium zirconium carbonate, zirconium oxide that is insoluble in water formed in the drying process after treatment, even in the absence of phosphate-based or boric acid-based incombustible chemicals, is a woody material such as algae, decaying fungi, and termites. This is due to the high resistance to the main organism that degrades the material. Therefore, in order to provide resistance to organisms that degrade woody materials such as algae, decaying fungi, termites, etc. by applying, immersing or impregnating a solution in which ammonium zirconium carbonate is dissolved, phosphoric acid or boric acid is used. The presence of non-combustible chemicals is not questioned.
なお、本明細書中において、木質材料とは、木材のみならず、合板、集成材、繊維板、ＬＶＬ、木粉と熱可塑性プラスチックとの複合材料、化学的、物理的改質処理をした木材のほか、ケナフやバガスなどの木材代替となるセルロース系の天然由来の資源を含め、それらの含有率が５０％を超えるものすべてを指し示すものとする。 In the present specification, the wood material is not only wood, but also plywood, laminated wood, fiberboard, LVL, composite material of wood powder and thermoplastic, wood subjected to chemical and physical modification treatment In addition, all of those containing more than 50%, including cellulosic natural resources that can substitute for wood such as kenaf and bagasse, shall be indicated.
木質材料に塗布等をしたリン酸イオン又はホウ酸イオンの滲み出しを防ぐには、その不溶化又は難溶化が不可欠であった。リン酸イオン又はホウ酸イオンの不溶化又は難溶化には、アルカリ土金属、ジルコニウム、チタン、マンガン、鉄、コバルト、ニッケル、銅、銀、亜鉛又はアルミニウムの塩、酸化物、水酸化物又は錯体のうち少なくとも１つ以上が溶解された溶液の塗布、含浸ならびにそれへの浸漬等が有効である。 In order to prevent leaching of phosphate ions or borate ions applied to a woody material, insolubilization or insolubilization has been indispensable. For insolubilization or insolubilization of phosphate ion or borate ion, alkaline earth metal, zirconium, titanium, manganese, iron, cobalt, nickel, copper, silver, zinc or aluminum salt, oxide, hydroxide or complex It is effective to apply, impregnate and soak in a solution in which at least one of them is dissolved.

In addition, borate ions are insolubilized by forming magnesium borate by dipping in a saturated aqueous solution of magnesium hydroxide, coating, impregnation, or the like.

なお、カルシウム又はマグネシウムの水酸化物はいずれも溶解度が低いので、処理に支障がある場合は、アンモニウム塩を助剤として足すことで、飛躍的に溶解度が向上することが確認されている。このように、助剤を用いて溶解度を高めることは課題を解決する上で、非常に有効な手段となるが、助剤の種類や使用の有無はここでは問われない。 In addition, since calcium or magnesium hydroxide has low solubility, it has been confirmed that the solubility can be drastically improved by adding an ammonium salt as an auxiliary agent when the treatment is hindered. As described above, increasing the solubility by using an auxiliary agent is a very effective means for solving the problem, but the type of auxiliary agent and whether or not the auxiliary agent is used are not questioned here.

Copper borate Insoluble Zinc borate Insoluble Aluminum borate Insoluble The above is quoted from the Dictionary of Chemistry (edited by Kyoritsu Publishing Co., Ltd.) For iron borate and cobalt borate, we could not find any data on solubility in particular. Since it is the same compound of Periodic Table 8 as nickel, it is probably considered insoluble.
ホウ酸銀、ホウ酸チタニウムについても特に溶解度についての資料を発見することはできなかったが、化学大辞典（共立出版社編）によれば、「アルカリ金属以外の金属のホウ酸塩は一般に難溶」とあることから、これらの塩も難溶か、不溶と考えられる。 We could not find any data on solubility of silver borate and titanium borate in particular, but according to the Dictionary of Chemistry (edited by Kyoritsu Shuppansha), “borate salts of metals other than alkali metals are generally difficult. These salts are also considered to be slightly soluble or insoluble.
