Description
本発明は、蓄光剤入りの木材及びその製造方法に関し、詳細には、蓄光剤含有の接着剤を用いた、蓄光剤入りの木材及び蓄光剤入り木材の製造方法に関する。 The present invention relates to a lumber containing a phosphorescent agent and a method for producing the same, and more particularly to a method for producing a lumber containing a phosphorescent agent and a lumber containing a phosphorescent agent using an adhesive containing the phosphorescent agent.
従来の内装施設部材、家具用材、外構用部材等に使用される発光性及び蓄光性を具備する材料は、非木質系のものとしては蓄光性顔料を合成樹脂に混入し成形したものが知られているが、木質系のものとしては、蓄光性顔料を混入した塗料を木材に塗布したものや、木材に蓄光性顔料を混入した合成樹脂を充填または接着したものが主流である。 Conventional non-wood-based materials used for interior facilities, furniture, exterior parts, etc. are made by mixing phosphorescent pigments into synthetic resin and molding them. However, wood-based ones are mainly those in which a paint mixed with a luminous pigment is applied to wood, or those in which a synthetic resin mixed with a luminous pigment is filled or adhered to wood.
直接人の手に触れる機会の多い内装施設部材、家具用材、外構用部材等は、合成樹脂製等の非木質系材料よりも木質系材料が好まれる。木材は多孔質材料であるため熱伝導率が低く、触ったときに暖かい印象を受け、手触りが好ましく感じるためである。また木材は暖色を呈し、目に有害とされる紫外線の反射も少ないため目に優しく、視覚的にも暖かい印象を受けるため好まれる。 Woody materials are preferred over non-woody materials such as synthetic resin for interior facility members, furniture materials, exterior members, etc., which are frequently touched by human hands. This is because wood is a porous material and has a low thermal conductivity, so that it feels warm when touched and feels good to the touch. In addition, wood is preferred because it has a warm color and has less reflection of ultraviolet rays that are harmful to the eyes.
木質系のものとして、木材に蓄光性顔料を混入した塗料を塗布する方法が、特許文献１及び特許文献２などにおいて記載されているが、これらの従来の場合には、十分な発光性及び蓄光性を発揮させるためには、多量に塗料を塗布して塗膜を厚くする必要があり、木材を内装施設部材、家具用材、外構用部材等に使用する上での利点である手触りや視覚的な暖かみが損なわれる。 A method of applying a paint mixed with a phosphorescent pigment to wood as a wood-based material is described in Patent Document 1 and Patent Document 2, etc., but in these conventional cases, sufficient light emission and phosphorescence are provided. In order to demonstrate its properties, it is necessary to apply a large amount of paint to thicken the coating film, which is an advantage when using wood as an interior facility member, furniture member, exterior member, etc. Warmth is lost.
そのほか木質系のものとして、木材に蓄光性顔料を混入した合成樹脂を接着または充填して成形することが、特許文献３及び特許文献４などにおいて記載されている。しかし成形後に、発光性及び蓄光性を有する外面について切削成形加工を行うと、木材部分と同時に蓄光性顔料を含有する合成樹脂を切削除去してしまうことになるため、成形後の切削加工が困難であり、収まりの調整や意匠が制限される。 In addition, as a wood-based material, Patent Document 3 and Patent Document 4 describe that molding is performed by bonding or filling a synthetic resin mixed with a phosphorescent pigment into wood. However, if the outer surface with luminous and luminous properties is cut and molded after molding, the synthetic resin containing the luminous pigment will be cut and removed at the same time as the wood part, so cutting after molding is difficult. Therefore, the adjustment of the fit and the design are limited.
特許文献５には、接着剤に蓄光性顔料を混入して木材を接着し、木質材料に発光性及び蓄光性を付与することが記載されている。特許文献５のやり方では、成形時に加圧接着を行うと、蓄光性顔料を含む接着剤の層が潰れて厚さを確保できず、十分な発光性及び蓄光性を得ることができない。 Patent Document 5 describes that a phosphorescent pigment is mixed in an adhesive and wood is bonded to impart light-emitting properties and phosphorescent properties to the wooden material. In the method of Patent Document 5, when pressure bonding is performed at the time of molding, the layer of the adhesive containing the phosphorescent pigment is crushed and the thickness cannot be ensured, and sufficient light emission and phosphorescence cannot be obtained.
従って、本発明の目的は、木材の特性である手触りや視覚的な暖かみ、切削加工の容易さを損なうことなく、木質材料に十分な発光性及び蓄光性を付与する、蓄光剤入りの木材及びその製造方法を提供することにある。 Accordingly, an object of the present invention is to provide a wood with a phosphorescent agent that imparts sufficient luminescence and phosphorescence to a wooden material without impairing the touch, visual warmth, and ease of cutting that are the characteristics of wood. It is in providing the manufacturing method.
本発明者は、木材の手触り等の特性を損なうことなく優れた発光性及び蓄光性を付与された木材を開発するため鋭意研究を行った結果、本発明を完成させるに至った。 As a result of earnest research to develop wood with excellent light-emitting properties and phosphorescent properties without impairing properties such as the feel of wood, the present inventors have completed the present invention.
上記目的を達成する本発明は、少なくとも２つの木材板が蓄光剤を含有した接着剤によって相互に接着されて成る、蓄光剤入りの木材であって、前記接着剤には前記蓄光剤の他に粒状物が含有されており、該粒状物によって前記少なくとも２つの木材の板の間の間隔が維持されている、ことを特徴とする木材を提供する。 The present invention for achieving the above object is a wood containing a phosphorescent agent, wherein at least two wood plates are bonded to each other by an adhesive containing a phosphorescent agent, and the adhesive includes the phosphorescent agent in addition to the phosphorescent agent. Provided is a wood characterized in that it contains a particulate material and maintains the spacing between the at least two wood plates by the particulate material.
上記木材において、前記接着剤に含有する粒状物の大きさが３．０mm以下である。その場合に、前記接着剤に含有する粒状物の大きさが０．５mm以上である。前記蓄光剤入り接着剤に含有する粒状物の割合が、総重量の１〜５０重量％である。前記粒状物は、透明または半透明材料で成る。前記粒状物は球状の粒状物である。その場合に、前記粒状物は、前記球状の粒状物の他に、粉砕物を含んでいる。また、前記粒状物には、蓄光剤が含有され、該蓄光剤を含有した該粒状物は、前記蓄光剤を含有する接着剤と同色に調製されているのが好ましい。 In the wood, the size of the granular material contained in the adhesive is 3.0 mm or less. In that case, the size of the granular material contained in the adhesive is 0.5 mm or more. The ratio of the granular material contained in the adhesive containing the phosphorescent agent is 1 to 50% by weight of the total weight. The granular material is made of a transparent or translucent material. The granular material is a spherical granular material. In that case, the said granular material contains the ground material other than the said spherical granular material. Moreover, it is preferable that the said granular material contains the luminous agent, and this granular material containing this luminous agent is prepared by the same color as the adhesive agent containing the said luminous agent.
また、本発明は、少なくとも２つの木材板を蓄光剤を含有した接着剤によって相互に加圧接着する、蓄光剤入りの木材の製造方法であって、前記接着剤に、前記蓄光剤の他に、粒状物を含有させて該接着剤を調整し、前記蓄光剤及び粒状物を含有した接着剤によって前記少なくとも２つの木材の板を相互に加圧して接着する、ことを特徴とする方法を提供する。 The present invention is also a method for producing wood containing a phosphorescent agent, wherein at least two wood plates are pressure-bonded to each other with an adhesive containing a phosphorescent agent.

To do.
上記方法においても、前記接着剤に含有する粒状物の大きさが３．０mm以下である。その場合、前記接着剤に含有する粒状物の大きさが０．５mm以上である。前記蓄光剤入り接着剤に含有する粒状物の割合が、総重量の１〜５０重量％である。前記粒状物が、透明または半透明材料で成る。前記粒状物が、球状の粒状物である。その場合、前記球状の粒状物の他に、粉砕物を含んでいる。また、前記粒状物に、蓄光剤が含有させて、該蓄光剤を含有した該粒状物を、前記蓄光剤を含有する接着剤と同色に調製するのが好ましい。 Also in the above method, the size of the granular material contained in the adhesive is 3.0 mm or less. In that case, the size of the granular material contained in the adhesive is 0.5 mm or more. The ratio of the granular material contained in the adhesive containing the phosphorescent agent is 1 to 50% by weight of the total weight. The granular material is made of a transparent or translucent material. The granular material is a spherical granular material. In that case, the pulverized material is included in addition to the spherical granular material. Moreover, it is preferable that the granular material contains a phosphorescent agent, and the granular material containing the luminous agent is prepared in the same color as the adhesive containing the luminous agent.
本発明において提供される、蓄光剤入りの木材及びその製造方法によれば、粒状物が木材板と木材板との間の間隔を確実に維持するので、加圧して接着されるときにおいて、蓄光剤を含む接着剤の層が潰れることがなくなり、蓄光剤を含む接着剤の層の厚さが確保されて、十分な発光性及び蓄光性を得ることができる。これによって、木材の手触り等の特性を損なうことなく優れた発光性及び蓄光性を付与された木材を得ることができる。 According to the timber containing the phosphorescent agent and the method for producing the same provided in the present invention, the granular material reliably maintains the interval between the timber board and the timber board, so that the phosphorescence is stored when being pressed and bonded. The adhesive layer containing the agent is not crushed, the thickness of the adhesive layer containing the phosphorescent agent is secured, and sufficient light-emitting properties and phosphorescent properties can be obtained. As a result, it is possible to obtain a wood having excellent light-emitting properties and phosphorescent properties without impairing properties such as the feel of the wood.
本発明に係る、蓄光剤入りの木材の１実施形態について、図１を参照して説明する。図１において、複数の木材板１は、蓄光剤を含有した接着剤２に、更に粒状物３を含有させた接着剤を用いて、相互に加圧接着される。粒状物３は、図示の例では、大径に球状の粒状物や小さな粉砕物等が混在した状態で、蓄光剤を含有した接着剤２に混入されている。粒状物２は、木材板１と木材板１との間の間隔を確実に維持するので、加圧して接着されるときにおいて、蓄光剤を含む接着剤２の層が潰れることがなくなり、蓄光剤を含む接着剤２の層の厚さが確保されて、十分な発光性及び蓄光性を得ることができる。なお、図１の実施形態においては、接着される木材板１は、３枚で示されているが、２枚だけでもよく、更には、３枚の木材板１のうち、蓄光剤及び粒状物含有の接着剤は、２枚の木材板１だけであってもよい。従って、本発明においては、少なくとも２枚の木材板が蓄光剤及び粒状物含有の接着剤によって接着されて所望の蓄光剤入り木材が製造される。 1 embodiment of the lumber containing a phosphorescent agent based on this invention is described with reference to FIG. In FIG. 1, a plurality of wood boards 1 are pressure-bonded to each other using an adhesive 2 containing a phosphorescent agent and an adhesive containing a granular material 3. In the example shown in the figure, the granular material 3 is mixed in the adhesive 2 containing a phosphorescent agent in a state where spherical granular materials having a large diameter, small pulverized materials, and the like are mixed. Since the granular material 2 maintains the space | interval between the wood board 1 and the wood board 1 reliably, when it pressurizes and adhere | attaches, the layer of the adhesive agent 2 containing a luminous agent is not crushed, and the luminous agent The thickness of the layer of the adhesive 2 containing is ensured, and sufficient luminous properties and luminous properties can be obtained. In the embodiment of FIG. 1, the three wood plates 1 to be bonded are shown, but only two pieces may be used. Furthermore, among the three wood plates 1, the phosphorescent agent and the granular material. Only two wood boards 1 may be contained. Therefore, in the present invention, at least two wood plates are bonded together with a phosphorescent agent and an adhesive containing particulate matter, thereby producing a desired lumber-containing wood.
本発明に係る、少なくとも２つの木材板１を、蓄光剤を含有した接着剤２によって相互に加圧接着する、蓄光剤入りの木材の製造方法では、前記の接着剤には、前記蓄光剤の他に、粒状物を含有させて接着剤を調整する。前記の蓄光剤及び粒状物を含有した前記接着剤を、少なくとも２つの木材板１の対向面に塗布して相互に加圧して接着する。木材板１の加圧接着は、例えば、木材板１の上面と下面を、機械的なクランプ装置で締め付けて、一定の力（例えば、１０Ｋｇｆ）で、一定時間（例えば、５〜６時間）、大気圧下で、加圧する。これによって、図１の木材が得られる。 According to the present invention, at least two wood plates 1 are pressure-bonded to each other with an adhesive 2 containing a phosphorescent agent. In the method for producing a wood with a phosphorescent agent, the adhesive includes the phosphorescent agent. In addition, an adhesive is prepared by containing a granular material. The adhesive containing the phosphorescent agent and the granular material is applied to the opposing surfaces of at least two wood boards 1 and bonded together by pressurizing them. The pressure bonding of the wood board 1 is performed, for example, by tightening the upper and lower surfaces of the wood board 1 with a mechanical clamping device, and with a certain force (for example, 10 Kgf) for a certain time (for example, 5 to 6 hours), Pressurize under atmospheric pressure. Thereby, the wood of FIG. 1 is obtained.
図１に示す実施形態においては、木材は、木材層１と蓄光剤及び粒状物３を含有する接着剤層２とから成り、交互に重なって接着されている。蓄光剤を含有する接着剤層２が木材表面に露出するため、木材は発光性及び蓄光性を発現する。また、接着剤層２は木料の内部にも存在する。従って、成形後に切削加工しても蓄光剤を含有する接着剤層２はその切削面において常に表面に露出する。これによって、特許文献３や４のように、発光性及び蓄光性を有する外面について切削成形加工を行うと、木材部分と同時に蓄光性顔料を含有する合成樹脂を切削除去してしまうおそれはなくなる。 In the embodiment shown in FIG. 1, the wood is composed of a wood layer 1 and an adhesive layer 2 containing a phosphorescent agent and a granular material 3, and are alternately overlapped and bonded. Since the adhesive layer 2 containing the phosphorescent agent is exposed on the surface of the wood, the wood exhibits light emission and phosphorescence. The adhesive layer 2 is also present inside the wood. Therefore, even if it cuts after shaping | molding, the adhesive bond layer 2 containing a luminous agent is always exposed to the surface in the cutting surface. Thus, as in Patent Documents 3 and 4, when cutting and forming is performed on the outer surface having luminous properties and luminous properties, there is no possibility of cutting and removing the synthetic resin containing the luminous pigment simultaneously with the wood portion.
本発明において、接着剤に混入する蓄光剤の割合は、接着剤及び蓄光剤の総重量の１〜５０重量％である。接着剤に混入する蓄光剤の量が１％以下の場合、接着剤層の発光性能が低く、消灯後に木質材料を十分に視認することができない。蓄光剤の量が５０重量％以上の場合、蓄光剤は粉体であるため接着剤への混入が困難になり、また成形後の木質材料の接着強度が低下するおそれがある。 In this invention, the ratio of the luminous agent mixed in an adhesive agent is 1 to 50 weight% of the total weight of an adhesive agent and a luminous agent. When the amount of the phosphorescent agent mixed in the adhesive is 1% or less, the light emitting performance of the adhesive layer is low, and the wooden material cannot be sufficiently visually recognized after the light is extinguished. When the amount of the phosphorescent agent is 50% by weight or more, since the phosphorescent agent is a powder, it is difficult to mix it into the adhesive, and the adhesive strength of the woody material after molding may be reduced.
接着剤に混入する蓄光剤は、希土類元素を含むアルカリ土類アルミン酸塩系蓄光性蛍光体、硫化亜鉛系蓄光性蛍光体等があり、より好適にはアルミン酸ストロンチウム系蓄光性蛍光体を挙げることができる。 Examples of the phosphorescent agent mixed in the adhesive include alkaline earth aluminate-based phosphorescent phosphors and zinc sulfide-based phosphorescent phosphors containing rare earth elements, and more preferably strontium aluminate phosphorescent phosphors. be able to.
接着剤には、蓄光剤のほかに、粒状物を混入する。この粒状物は、加圧接着時において物理的に木材層同士の密着を阻害し、接着剤層に厚さを与えることができる。粒状物を混入しない場合、成形時に加圧接着を行うと、蓄光剤を含有する接着剤層が潰れて厚さを確保できず、十分な発光性及び蓄光性の木質材料を得ることができない。 In addition to the phosphorescent agent, a granular material is mixed in the adhesive. This granular material can physically inhibit the adhesion between the wood layers during pressure bonding, and can give a thickness to the adhesive layer. In the case where no particulate matter is mixed, if pressure bonding is performed at the time of molding, the adhesive layer containing the phosphorescent agent is crushed and the thickness cannot be ensured, and a sufficient luminescent and phosphorescent woody material cannot be obtained.
接着剤には、０．５〜３．０mmの範囲の大きさの粒状物を混入する。粒状物の大きさが０．５mm以下の場合、木材層同士の密着を阻害する効果が低く、木質材料に十分な発光性及び蓄光性を付与することができない。粒状物の大きさが、３．０mm以上の場合、木材層同士の間隔が広すぎるため接着剤層は気泡を含みやすくなり、木材層間の接着不良が発生する。 A granular material having a size in the range of 0.5 to 3.0 mm is mixed in the adhesive. When the size of the granular material is 0.5 mm or less, the effect of inhibiting the adhesion between the wood layers is low, and sufficient light-emitting properties and phosphorescent properties cannot be imparted to the woody material. When the size of the granular material is 3.0 mm or more, since the interval between the wood layers is too wide, the adhesive layer tends to contain air bubbles, resulting in poor adhesion between the wood layers.
粒状物は、蓄光剤入り接着剤に対し、蓄光剤と接着剤と粒状物の総重量の１〜５０重量％の割合で混入する。前述と同様に、粒状物の割合が１重量％以下の場合、木材層同士の密着を阻害する効果が低く、また５０重量％以上の場合、接着剤層に気泡を含みやすくなるためである。 A granular material mixes with the ratio of 1 to 50 weight% of the total weight of a luminous agent, an adhesive agent, and a granular material with respect to the adhesive with a luminous agent. As described above, when the proportion of the granular material is 1% by weight or less, the effect of inhibiting the adhesion between the wood layers is low, and when it is 50% by weight or more, the adhesive layer easily contains bubbles.
粒状物は、シリカゲル及びその他のケイ酸塩、炭酸塩、塩化物などの無機化合物、ロジンや天然ゴムなどの天然樹脂、フェノール樹脂、エポキシ樹脂、メラミン樹脂、ユリア樹脂、不飽和ポリエステル樹脂、アルキド樹脂、ポリウレタン、ポリイミド、ポリエチレン、ポリプロピレン、ポリ塩化ビニル、ポリスチレン、アクリル樹脂、ポリアミド、ポリアセタール、ポリカーボネート、変性ポリフェニレンエーテル、ポリブチレンテレフタレート、ポリエチレンテレフタレートなどの合成樹脂等から成るものを、単独または複数を選択して使用する。 Granules are silica gel and other inorganic compounds such as silicates, carbonates and chlorides, natural resins such as rosin and natural rubber, phenolic resins, epoxy resins, melamine resins, urea resins, unsaturated polyester resins, alkyd resins. Select one or more of synthetic resins such as polyurethane, polyimide, polyethylene, polypropylene, polyvinyl chloride, polystyrene, acrylic resin, polyamide, polyacetal, polycarbonate, modified polyphenylene ether, polybutylene terephthalate, polyethylene terephthalate, etc. To use.
粒状物は、透明または半透明であるのが好ましい。粒状物が透明または半透明以外である場合、接着剤層に粒状物が現れると、その部位は発光性及び蓄光性を持たないため、接着剤層は断続的な層となって発光し、木質材料の発光性及び蓄光性が低下する。これに対して、粒状物が透明または半透明である場合、接着剤層に粒状物が現れても、粒状物は光を透過するため、接着剤層の発光性及び蓄光性を阻害せず、連続的に発光する接着剤層が得られる。 The granular material is preferably transparent or translucent. If the granular material is other than transparent or translucent, when the granular material appears in the adhesive layer, the part does not have light emission and luminous properties, so the adhesive layer becomes an intermittent layer and emits light. Luminous properties and luminous properties of the material are reduced. On the other hand, when the granular material is transparent or translucent, even if the granular material appears in the adhesive layer, since the granular material transmits light, it does not hinder the light-emitting property and the luminous property of the adhesive layer, An adhesive layer that emits light continuously is obtained.
粒状物は、透明または半透明であるほか、さらに安価にかつ安定的に供給できるものが望ましい。このような粒状物の代表的なものとして、シリカゲル（SiO2・nH2O：非晶質ケイ(珪)酸）を挙げることができる。 The granular material is preferably transparent or translucent, and can be supplied more inexpensively and stably. A typical example of such a granular material is silica gel (SiO 2 · nH 2 O: amorphous silicic acid).
粒状物は、蓄光剤を含有し、かつ蓄光剤を含有する接着剤と同色に調製されたものがさらに好適である。この粒状物を使用した場合、接着剤層に粒状物が現れても、明るい場所では接着剤層と粒状物は同色であるため同化して見え、また消灯時には接着剤層と粒状物の両方が発光性及び蓄光性を発現し、接着剤層が連続的に発光するためである。 More preferably, the granular material contains a phosphorescent agent and is prepared in the same color as the adhesive containing the phosphorescent agent. When this granular material is used, even if the granular material appears in the adhesive layer, the adhesive layer and the granular material appear to be assimilated in a bright place because they are the same color, and both the adhesive layer and the granular material appear when turned off. It is because the adhesive layer emits light continuously by exhibiting luminescent property and luminous property.
接着剤は、セラミック、セメント類、ケイ酸ソーダ類等を主成分とする無機系接着剤、天然ゴム、膠、カゼイン、セラックなどを主成分とする有機天然系接着剤、酢酸ビニル、塩化ビニル、アクリル、スチレン、ポリアミド、アルキド、セルロース、シアノアクリレート、飽和ポリエステル、ポリウレタン、フェノキシ、ポリスルホン、ポリアリルスルホン、フェノール、レゾルシノール、ユリア、メラミン、フラン、エポキシ、不飽和ポリエステル、イソシアネート、シリコーン、アクリル酸ジエステル、スチレンゴム、ブチルゴム、ポリクロロプレン、二トリルゴム、ポリサルファイドなどを主成分とする有機合成系接着剤等から選択される。 Adhesives include inorganic adhesives based on ceramics, cements, sodium silicates, etc., organic natural adhesives based on natural rubber, glue, casein, shellac, etc., vinyl acetate, vinyl chloride, Acrylic, styrene, polyamide, alkyd, cellulose, cyanoacrylate, saturated polyester, polyurethane, phenoxy, polysulfone, polyallylsulfone, phenol, resorcinol, urea, melamine, furan, epoxy, unsaturated polyester, isocyanate, silicone, acrylic diester, It is selected from organic synthetic adhesives mainly composed of styrene rubber, butyl rubber, polychloroprene, nitrile rubber, polysulfide and the like.
木材の種類には、特に限定されず、種々の木材を用いることができ、例えば、スギ、ヒノキ、スプルースなどの針葉樹、ブナ、ナラ、キリなどの広葉樹、ラワン、黒檀、チークなどの南洋材等の心材や辺材の他に、集成材、ＬＶＬ（Laminated Veneer Lumber：単板積層材）、合板、ＭＤＦ（Medium Density Fiberboard：中質繊維板）、パーティクルボード、ＯＳＢ（Oriented Strand Board：配向性ストランドボード)等の木質接着製品、木材と合成樹脂を複合し成形したＷＰＣ（Wood Plastic Composite：木材・プラスチック複合材）も用いることができる。 There are no particular restrictions on the type of wood, and various types of wood can be used. In addition to core and sapwood, laminated wood, LVL (Laminated Veneer Lumber), plywood, MDF (Medium Density Fiberboard), particle board, OSB (Oriented Strand Board) Wood adhesive products such as board), and WPC (Wood Plastic Composite) formed by combining wood and synthetic resin can also be used.
本発明の実施例について、以下説明する。なお、本発明はこの実施例に限定されるものではなく、本発明の趣旨に適合し得る範囲で適当に変更を加えて実施することも可能であり、それらはいずれも本発明の技術的範囲に含まれる。 Examples of the present invention will be described below. The present invention is not limited to this embodiment, and can be implemented with appropriate modifications within a range that can be adapted to the gist of the present invention, all of which are within the technical scope of the present invention. include.
根本特殊化学（株）製の蓄光性蛍光体（商品名：N夜光ルミノーバGLL-300F）を、２０重量％、目開き１．４mmのふるいにかけたシリカゲルを１０重量％の割合でエポキシ樹脂接着剤に入れ、よく混練する。このようにして得られた蓄光剤及び粒状物含有接着剤を、特に断りがない場合、以下単に接着剤と呼称する。 Epoxy resin adhesive at a rate of 10% by weight silica gel obtained by screening a phosphorescent phosphor made by Nemoto Special Chemical Co., Ltd. (trade name: N Yoko Luminova GLL-300F) with a sieve of 20% by weight and 1.4 mm aperture. And knead well. The phosphorescent agent and the granular material-containing adhesive thus obtained are hereinafter simply referred to as an adhesive unless otherwise specified.
木材は両面を鉋で厚さ７mmに調製されたスギ単板を用いる。スギ単板に接着剤を４００g/m2塗布し、別に用意したスギ単板を重ねる。新たに重ねたスギ単板に、同様に接着剤を４００g/m2塗布し、また新たに別のスギ単板を重ねる。この作業を６回繰り返し、接着剤を介在して重ねた６枚の木材片を得る。 As for wood, a cedar veneer prepared on both sides with a thickness of 7 mm is used. Apply 400 g / m 2 of adhesive to the cedar veneer, and stack the cedar veneers separately prepared. Similarly, 400 g / m 2 of adhesive is applied to a newly stacked cedar veneer, and another cedar veneer is additionally stacked. This operation is repeated six times to obtain six pieces of wood stacked with an adhesive interposed therebetween.
上記木材片を、クランプを用いて圧締し、室温にて５時間、静置する。５時間経過した後、クランプを外して、木材層が６層、及び木材層の間の接着剤層が５層からなる接着成形した木材接着成形物を得た。なお、クランプを用いて圧締は、通常の加圧であり、例えば、１０ｋｇｆ程度である。 The piece of wood is pressed using a clamp and allowed to stand at room temperature for 5 hours. After 5 hours, the clamp was removed, and an adhesive-molded wood adhesive molded article comprising 6 wood layers and 5 adhesive layers between the wood layers was obtained. Note that pressing with a clamp is normal pressurization, for example, about 10 kgf.
このようにして得られた木材接着成形物は、粒状物が木材板と木材板との間の間隔を確実に維持するので、蓄光剤を含む接着剤の層が潰れることがなくなり、蓄光剤を含む接着剤の層の厚さが確保されて、十分な発光性及び蓄光性を得ることができた。従って、円筒形に切削加工しても接着剤層が表面に露出し、また接着剤層は適度な厚さを持っているため、消灯時には高い発光性及び蓄光性を発現した。また切削加工を施した木材接着成形物の手触りや外観は、木材の持つ特性である暖かみを損なわず、通常の木材製材品と同等であった。 In the wood adhesive molded product thus obtained, the granular material reliably maintains the distance between the wood board and the wood board, so that the layer of the adhesive containing the phosphorescent agent is not crushed, and the phosphorescent agent is not used. The thickness of the adhesive layer to be included was ensured, and sufficient light emission and phosphorescence could be obtained. Therefore, the adhesive layer is exposed on the surface even after being cut into a cylindrical shape, and the adhesive layer has an appropriate thickness, so that high light-emitting properties and light-accumulating properties were exhibited when the lights were turned off. In addition, the touch and appearance of the wood-bonded molded product subjected to the cutting processing were the same as ordinary wood lumber products without impairing the warmth characteristic of wood.
なお、蓄光剤の外に、接着剤に、防腐剤、防蟻剤、難燃剤、及び蓄熱剤を、単独又は複数選択して混合するとともに、既述の粒状物を含有させて、少なくとも２つの木材板を加圧接着してもよい。これによって、形成された木材には、防腐性、防蟻性、難燃性、蓄熱性が追加される。この場合の粒状物の大きさ及び割合は、既述のとおり、０．５〜３．０mmの範囲の大きさにされ、また、蓄光剤入り接着剤と粒状物の総重量の１〜５０重量％の割合にされる。更に、その場合に、蓄光剤に代えて、接着剤に、防腐剤、防蟻剤、難燃剤及び蓄熱剤を、単独又は複数選択して混合するとともに、既述の粒状物を含有させて、少なくとも２つの木材板を加圧接着することもできる。この場合、形成された木材には、蓄光性はないが、防腐性、防蟻性、難燃性、蓄熱性が得られる。 In addition to the phosphorescent agent, the adhesive contains an antiseptic, an antproofing agent, a flame retardant, and a heat storage agent, either alone or in combination, and mixed with at least two of the aforementioned granular materials. A wood board may be pressure-bonded. Thereby, antiseptic property, ant repellency property, flame retardancy, and heat storage property are added to the formed wood. In this case, the size and ratio of the granular material are in the range of 0.5 to 3.0 mm as described above, and 1 to 50 weight of the total weight of the adhesive containing the phosphorescent agent and the granular material. %. Furthermore, in that case, in place of the phosphorescent agent, the adhesive is preservative, anti-anticide, flame retardant and heat storage agent, either alone or in combination, and mixed with the particulate matter described above, At least two wood boards can be pressure bonded. In this case, the formed wood does not have a luminous property, but antiseptic properties, ant-proofing properties, flame retardancy, and thermal storage properties are obtained.
本発明の木材の接着成形方法によって得られる木材は、木材の手触り等の特性を損なうことなく優れた発光性及び蓄光性が付与されるので、内装施設部材、家具用材、外構用部材等に使用される発光性及び蓄光性を具備する材料に極めて有用である。また成形する木材に間伐材を利用することにより、自然環境の保護にも貢献することができる。 The wood obtained by the wood adhesive molding method of the present invention is imparted with excellent luminescence and phosphorescence without impairing properties such as the feel of wood, so it can be used for interior facility members, furniture materials, exterior members, etc. It is extremely useful for the material having the luminescent property and the luminous property used. In addition, by using thinned wood for the wood to be molded, it can contribute to the protection of the natural environment.
