Description

本願発明は、水廻り用木材に耐水性を付与するための木材の処理方法に関する。   The present invention relates to a method for treating wood for imparting water resistance to watering wood.

従来、浴室、トイレなどの水廻りに木材を用いる場合、カビの発生や、腐敗、汚れなどの問題があるため、木材に何らかの処理を行い、耐水性を付与することが行われてきた。木材に耐水性を付与する処理方法としては、木材に樹脂を含浸させるＷＰＣ（Ｗｏｏｄ Ｐｌａｓｔｉｃ Ｃｏｍｂｉｎａｔｉｏｎ）や、木材に不活性ガス雰囲気下で加熱処理を行う（例えば、特開平６−１５８８３０号公報）方法などが挙げられる。   Conventionally, when wood is used around water in bathrooms, toilets, etc., there are problems such as generation of mold, spoilage, dirt, etc., so that some treatment has been applied to the wood to impart water resistance. As a treatment method for imparting water resistance to wood, WPC (Wood Plastic Combination) in which wood is impregnated with resin, or heat treatment of wood in an inert gas atmosphere (for example, JP-A-6-158830) Etc.

しかしながら、ＷＰＣでは木材の細胞壁や細胞内腔に樹脂が含浸されるために耐水性が向上するものの、木材の表層に樹脂が多く含まれることで木材の風合いが損なわれてしまうという問題があった。一方、不活性ガス雰囲気下で加熱処理を行うと、木材細胞中の水酸基が減少し、耐水性が向上するものの、木材の表面は多孔質のままであり、汚れが付着しやすく、又、一度汚れが付着してしまうと除去しにくかった。
特開平６−１５８８３０号公報 However, in WPC, although water resistance is improved because the resin is impregnated into the cell walls and cell lumens of wood, there is a problem that the texture of the wood is impaired due to a large amount of resin in the surface layer of wood. . On the other hand, when heat treatment is performed in an inert gas atmosphere, the hydroxyl groups in the wood cells are reduced and the water resistance is improved, but the surface of the wood remains porous, and dirt is easily attached. It was difficult to remove the dirt.
JP-A-6-158830

本願発明は、上記背景技術に鑑みて発明されたものであり、その課題は、木材に、その風合いを生かしながら、耐水性及び防汚性を付与する木材の加工方法を提供することである。   This invention is invented in view of the said background art, The subject is providing the processing method of the wood which provides water resistance and antifouling property, making use of the texture to wood.

上記課題を解決するために、本願発明の請求項１に係る木材の処理方法においては、木材の処理方法であって、不活性ガス雰囲気下で木材を加熱処理した後、その表面を研磨し、研磨された表面に塗料を塗布することで、木材の表面の凹凸に沿って塗膜層を形成することを特徴とするものである。
又、請求項２記載の木材の処理方法においては、塗料が、ウレタン樹脂を主成分とし、ファインセラミックスを含有したものであることを特徴とするものである。 In order to solve the above problems, in the wood treatment method according to claim 1 of the present invention, the wood treatment method, after heat-treating the wood in an inert gas atmosphere, the surface is polished, The coating layer is formed along the unevenness of the surface of the wood by applying a paint to the polished surface.
In the wood processing method according to claim 2, the paint is mainly composed of a urethane resin and contains fine ceramics.

又、請求項３記載の木材の処理方法においては、塗布される塗料の不揮発成分が、２〜２０ｇ／ｍ2となるように塗布することを特徴とするものである。 According to a third aspect of the present invention, there is provided a method for treating wood, wherein the non-volatile component of the paint to be applied is 2 to 20 g / m 2 .

本願発明の請求項１に係る木材の処理方法によると、不活性ガス雰囲気下で木材を加熱処理することで耐水性を付与できる。更に、木材の表面を研磨し、研磨された表面に塗料を塗布することで、木材の表面の凹凸に沿って塗膜層を形成することで、塗料を塗布しても木材表面の凹凸が残り、木材の風合いを生かしながらその表面に防汚性を付与することができる。
又、請求項２に係る木材の処理方法によると、塗料が、ウレタン樹脂を主成分とし、ファインセラミックスを含有したものであるため、磨耗性、耐候性に優れた木材となる。
又、請求項３に係る木材の処理方法によると、塗布される塗料の不揮発成分が、２〜２０ｇ／ｍ2であるため、木材表面の凹凸に沿って塗料が塗布され、塗布量が多すぎて木材表面の凹凸がなくなることで木材の風合いが損なわれたり、塗布量が少なすぎて塗りむらが生じたりすることがない。 According to the wood processing method of the present invention, water resistance can be imparted by heat-treating wood in an inert gas atmosphere. Furthermore, by polishing the surface of the wood and applying a paint to the polished surface, a coating layer is formed along the unevenness of the surface of the wood, so that the unevenness of the wood surface remains even when the paint is applied. It is possible to impart antifouling properties to the surface while making use of the texture of wood.
According to the wood processing method of claim 2, since the paint is mainly composed of a urethane resin and contains fine ceramics, the wood is excellent in wear and weather resistance.
Further, according to the wood processing method according to claim 3, since the non-volatile component of the applied paint is 2 to 20 g / m 2 , the paint is applied along the unevenness of the wood surface, and the application amount is too large. As a result, the texture of the wood is not impaired by eliminating the irregularities on the surface of the wood, and the coating amount is too small to cause uneven coating.

この実施形態の木材の処理方法は、不活性ガス雰囲気下で木材１を加熱処理した後、その表面を研磨し、研磨された表面に塗料を塗布することで、木材１の表面の凹凸に沿って塗膜層２を形成している。
又、塗料が、ウレタン樹脂を主成分とし、ファインセラミックスを含有したものである。
又、塗布される塗料の不揮発成分が、２〜２０ｇ／ｍ2となるように塗布している。 In the wood processing method of this embodiment, after heat-treating the wood 1 in an inert gas atmosphere, the surface is polished, and a paint is applied to the polished surface so that the surface of the wood 1 is uneven. Thus, the coating layer 2 is formed.
Further, the coating material is mainly composed of urethane resin and contains fine ceramics.
Moreover, it has apply | coated so that the non-volatile component of the coating material to apply | coat may be 2-20 g / m < 2 >.

以下、この実施形態の木材の処理工程を、より具体的詳細に説明する。この実施形態の木材の処理方法は、木材１を不活性ガス雰囲気下で加熱処理する工程と、加熱処理された木材１の表面を研磨する工程、研磨された表面に塗料を塗布する工程とからなっている。   Hereinafter, the wood treatment process of this embodiment will be described in more detail. The wood processing method of this embodiment includes a step of heat-treating the wood 1 in an inert gas atmosphere, a step of polishing the surface of the heat-treated wood 1 and a step of applying a paint to the polished surface. It has become.

まず、木材１を熱処理釜に入れて減圧することで脱気した後、不活性ガスを導入して加圧し、加熱処理を行う。このとき用いる不活性ガスとしては、ヘリウムやアルゴンなどの希ガス、窒素や二酸化炭素などから１種類のみを用いるか、もしくは２種類以上を混合して用いても良い。
又、加熱する温度は、１００〜２５０℃が好ましく、更に好ましくは１６０〜１８０℃である。１００℃以下であると木質の乾燥、すなわち水分の蒸発が起こるのみであり、木材１の性質の改善、すなわち木材１細胞中の水酸基の減少が起こりにくい。又、２５０℃以上であると木材１の炭化が起こりやすく、機械的強度の低下や変色のおそれがある。又、加熱時間は木材１の種類や形状によっても異なるが、５〜３０時間が望ましい。
続いて、木材１の表面を研磨する。このときの研磨の目的は、木材表面のささくれを削り略平面とすることで、この後の工程で塗料を塗布するとき、塗料を均一に塗布しやすくすると共に、その接着性を高めることであるため、木目出しを行う必要はない。研磨をする方法としては、サンドペーパーを用いて手作業で行っても、ベルトサンダーやワイドサンダーなどの研磨機を用いて行ってもよい。
最後に、研磨した木材１に塗料を塗布する。このとき用いる塗料としては、ウレタン樹脂、アクリル樹脂、メラミン樹脂、フェノール樹脂及びジアリールフタレート樹脂などを主成分として含むものなどが挙げられる。この場合、ウレタン樹脂を用いている。更に、この塗料は、ファインセラミックを含有していてもよい。ファインセラミックとしては、シリカ、アルミナ、タルク、マイカなどが挙げられる。これらのファインセラミックはこれらのいずれかを単独で用いても良いし、２種類以上を併用して用いても良い。
塗料を塗布するときには、上記の樹脂やファインセラミックスなどの塗料成分をシンナーなどの有機溶媒で希釈し、塗布する。塗布の方法は、はけなどを用いて行っても良いが、この場合、塗料用のスプレー装置を用いてスプレー塗装している。塗料を塗布する量は、塗料の不揮発成分が２〜２０ｇ／ｍ2となるように塗布する。例えば、不揮発成分が２０質量％になるようにシンナーで希釈した塗料を、３０ｇ／ｍ2となるように塗布することにより、木材１表面には塗料の不揮発成分が６ｇ／ｍ2である塗膜層２が形成される。このように、塗料の希釈度及び塗布量は、塗料の不揮発成分が２〜２０ｇ／ｍ2となるように調節する。上記の塗装方法をとることで、図１に示す如く、木材１表面の動管や師管などによって形成されている凹凸に沿って塗膜層２が形成される。塗料の不揮発成分が、これ以上であると木材１表面の凹凸に関係なく平坦な塗膜層２が形成されて木材１の風合いが失われ（図２）、これ以下である場合には塗料の塗りむらが発生する（図３）おそれがある。
従って、この実施形態の木材１の加工方法においては、不活性ガス雰囲気下で木材１を加熱処理した後、その表面を研磨し、研磨された表面に塗料を塗布することで、木材１の表面の凹凸に沿って塗膜層２を形成するため、木材１が加熱処理されることで改質が起こることで耐水性が付与されると共に、その表面の凹凸に沿って塗膜層２が形成されるために木材１の風合いを生かしながら防汚性が付与される。又、加熱処理することにより木材１の平衡含水率が低下するため、塗料が浸透しやすい状態となっており、塗料の塗りむらを防ぐことができると共に、木材１の表面に厚い塗膜層２が形成されにくく、木材１表面の凹凸に沿って薄い塗膜層２が形成され、木材１の風合いがより生かされた木材１を製造できる。又、加熱処理後の木材１の表面を研磨することで、更に塗料の塗りむらを防ぎ、塗料の密着性を向上させることで耐摩耗性を向上させることができる。このことは、この実施形態の木材１の処理方法では、木材１表面の凹凸に沿って塗膜層２が形成される、すなわち木材１表面の形状がそのまま保持されるため、予め木材１の表面を平滑化しておくことで、木材１の仕上がりを良くすることができる。
又、塗料が、ファインセラミックスを含有したウレタン樹脂であるため、耐摩耗性や防汚性が付与される。この木材１の処理方法においては、木材１表面の凹凸を生かし、その風合いを生かすためには薄い塗膜層２を形成することが必要であるが、塗料にファインセラミックを含有させることで、薄い塗膜層２であっても高い耐摩耗性を有するために非常に効果的である。 First, after degassing by putting the wood 1 in a heat treatment kettle and depressurizing, an inert gas is introduced and pressurized to perform heat treatment. As the inert gas used at this time, only one kind from rare gases such as helium and argon, nitrogen and carbon dioxide, or a mixture of two or more kinds may be used.
The heating temperature is preferably 100 to 250 ° C, more preferably 160 to 180 ° C. When the temperature is 100 ° C. or less, only the drying of the wood, that is, the evaporation of water occurs, and the property of the wood 1 is improved, that is, the reduction of the hydroxyl groups in the wood 1 cells hardly occurs. On the other hand, when the temperature is 250 ° C. or higher, the wood 1 is easily carbonized, and there is a risk that the mechanical strength is lowered or discolored. The heating time varies depending on the type and shape of the wood 1, but is preferably 5 to 30 hours.
Subsequently, the surface of the wood 1 is polished. The purpose of polishing at this time is to make the rough surface of the wood surface sharpened, so that when applying the paint in the subsequent process, it is easy to apply the paint uniformly and to increase its adhesion. Therefore, it is not necessary to perform wood graining. As a method of polishing, it may be performed manually using sandpaper or using a polishing machine such as a belt sander or a wide sander.
Finally, a paint is applied to the polished wood 1. Examples of the paint used at this time include those containing, as a main component, a urethane resin, an acrylic resin, a melamine resin, a phenol resin, a diaryl phthalate resin, and the like. In this case, urethane resin is used. Furthermore, this paint may contain a fine ceramic. Examples of the fine ceramic include silica, alumina, talc, and mica. These fine ceramics may be used either alone or in combination of two or more.
When applying the paint, the paint components such as the above resin and fine ceramics are diluted with an organic solvent such as thinner and applied. The application method may be performed using a brush or the like, but in this case, spray coating is performed using a paint spray device. The amount of coating is applied so that the nonvolatile component of the coating is 2 to 20 g / m 2 . For example, a coating nonvolatile component was diluted with a thinner so that 20 mass%, by applying such that the 30 g / m 2, coating the wood 1 surface nonvolatile components of the coating material is 6 g / m 2 Layer 2 is formed. Thus, the dilution degree and the coating amount of the paint are adjusted so that the non-volatile component of the paint is 2 to 20 g / m 2 . By taking the above-mentioned coating method, as shown in FIG. 1, the coating layer 2 is formed along the unevenness formed by the moving tube, the teacher tube, etc. on the surface of the wood 1. When the non-volatile component of the paint is more than this, a flat coating layer 2 is formed regardless of the unevenness of the surface of the wood 1 and the texture of the wood 1 is lost (FIG. 2). There is a risk of uneven coating (FIG. 3).
Therefore, in the processing method of the wood 1 of this embodiment, the surface of the wood 1 is obtained by heat-treating the wood 1 in an inert gas atmosphere, polishing the surface, and applying a paint to the polished surface. In order to form the coating film layer 2 along the unevenness of the film, the heat treatment is applied to the wood 1 to impart water resistance, and the coating film layer 2 is formed along the unevenness of the surface. Therefore, antifouling properties are imparted while taking advantage of the texture of the wood 1. Moreover, since the equilibrium moisture content of the wood 1 is reduced by the heat treatment, the paint is in a state of being easily infiltrated, so that coating unevenness can be prevented and a thick coating layer 2 is formed on the surface of the wood 1. Can be formed, and the thin coating layer 2 is formed along the unevenness of the surface of the wood 1, so that the wood 1 in which the texture of the wood 1 is further utilized can be manufactured. Further, by polishing the surface of the wood 1 after the heat treatment, it is possible to further prevent uneven coating of the paint and to improve the wear resistance by improving the adhesion of the paint. This is because, in the method for treating wood 1 according to this embodiment, the coating layer 2 is formed along the irregularities on the surface of the wood 1, that is, the shape of the surface of the wood 1 is maintained as it is. By smoothing, the finish of the wood 1 can be improved.
Moreover, since the paint is a urethane resin containing fine ceramics, wear resistance and antifouling properties are imparted. In this method for treating wood 1, it is necessary to make use of the unevenness of the surface of wood 1 and to form a thin coating layer 2 in order to make use of the texture. Even the coating layer 2 is very effective because it has high wear resistance.

塗布される塗料の不揮発成分が、２〜２０ｇ／ｍ2となるように塗布するため、塗料の塗りむらを防ぐ一方、塗料が木材１表面の凹凸を埋めてしまうような厚塗りを防ぐことで木材１の風合いを保持することができる。つまり、これにより木材１表面の凹凸に沿ってむらなく塗膜層２が形成される。 Since the non-volatile component of the paint to be applied is 2 to 20 g / m 2 , it prevents the paint from being unevenly coated, while preventing the paint from being thickly coated to fill the uneven surface of the wood 1. The texture of the wood 1 can be maintained. That is, the coating layer 2 is thereby formed uniformly along the unevenness of the surface of the wood 1.
