従来、自動車の内装部品、家具、電気器機などに、木目柄を有する合成樹脂複 合成形品が広く使用されている。 このような木目柄の複合成形品をつくるには、突板とよばれる木材単板、不織 布等で裏打ち補強された単板等の木質材薄板が表面材として用いられ、これを射 出成形型内に配置し、芯材となる合成樹脂を射出してインサート成形する方法な どが行われていた。 ところで、このような方法によって得られた複合成形品は、意匠性に優れてい るが、成形品の形状が複雑になると、表面の木質材薄板に割れを生じ、製品不良 が発生し易くなるという問題があった。あるいは、複合成形体の表面に塗装を施 した後、バフ研磨によって表面仕上げを行うと、バフ研磨時の摩擦熱によって界 面の樹脂が軟化し、表面に細かい凹凸が発生する。そのため、吹上げによる鏡面 仕上げ、あるいは艶消し仕上げ等をしなければならなかった。 Conventionally, synthetic resin composite molded products having a wood grain pattern have been widely used for interior parts of automobiles, furniture, electric appliances and the like. In order to make such a composite product with a wood grain pattern, a thin wood plate, such as a veneer wood veneer or a veneer reinforced with a non-woven cloth, is used as the surface material. For example, a method of placing in a mold and injecting a synthetic resin as a core material to perform insert molding has been performed. By the way, the composite molded product obtained by such a method is excellent in design, but if the shape of the molded product becomes complicated, cracks will occur in the wood thin plate on the surface and product defects will easily occur. There was a problem. Alternatively, if the surface of the composite molded body is painted and then the surface is finished by buffing, frictional heat at the time of buffing softens the resin on the interface, resulting in fine irregularities on the surface. Therefore, it had to be mirror finished by blowing up or matte finish.
【０００３】 そのような問題を解決するために、射出成形金型内にインサートする表面材と して、木質単板の裏面にアルミニウム薄板を積層一体化したものを用いて成形す る方法が開発された。この方法によれば、木質単板はアルミニウム薄板によって 補強されているので、複雑な形状の複合成形品に用いても破損することがなく、 美しい木目柄の製品が得られる。また、これをバフ研磨しても、表面に細かい凹 凸模様があらわれることがないという利点を有するものである。 そしてこの方法において、アルミニウム薄板と合成樹脂芯材との接着性を得る ために、合成樹脂と接するアルミニウム薄板の表面上に、接着剤を塗布する方法 、あるいは合成樹脂と接するアルミニウム薄板の表面上に、予めアルミニウム溶 射処理を施し、噴霧されたアルミニウムの間隙に溶融した合成樹脂が侵入するア ンカー効果によって、これらを接合する方法等が行われている。In order to solve such a problem, as a surface material to be inserted into an injection molding die, a method has been developed in which a thin aluminum plate is laminated and integrated on the back surface of a wood veneer. Was done. According to this method, since the wood veneer is reinforced by the thin aluminum plate, it will not be damaged even when used in a complex molded product having a complicated shape, and a product with a beautiful wood grain pattern can be obtained. Further, even if this is buffed, it has an advantage that fine concave and convex patterns do not appear on the surface. In this method, in order to obtain the adhesiveness between the aluminum thin plate and the synthetic resin core material, a method of applying an adhesive on the surface of the aluminum thin plate in contact with the synthetic resin, or a method of applying the adhesive on the surface of the aluminum thin plate in contact with the synthetic resin A method has been performed in which aluminum is sprayed in advance, and the molten synthetic resin is joined into the gap of the sprayed aluminum by an anchor effect so that they are joined.

しかしながら、そのような方法では、表面材と合成樹脂芯材との接着性が十分 でなく、複合成形品の製造工程中あるいは製品の使用中に剥離が生じる恐れがあ る等、耐久性が乏しいものであった。 However, in such a method, the adhesiveness between the surface material and the synthetic resin core material is not sufficient, and peeling may occur during the manufacturing process of the composite molded product or during use of the product, resulting in poor durability. It was a thing.
【０００５】 この考案は前記事情に鑑みてなされたもので、射出成形金型内に表面材を配置 し、合成樹脂をインサート成形して複合成形品を成形する際の表面材等として用 いられる木質化粧板において、表面材としての強度を維持しつつ、これと合成樹 脂芯材との接着性を向上できるようにした木質化粧板の提供を目的とする。The present invention has been made in view of the above circumstances, and is used as a surface material or the like when a composite molded article is formed by placing a surface material in an injection molding die and insert molding a synthetic resin. It is an object of the present invention to provide a wood decorative board which is capable of improving the adhesiveness between the wood decorative board and a synthetic resin core material while maintaining the strength as a surface material.

この考案の木質化粧板は、金属薄板を中間層として、その一面上に木質単板を 積層し、他面上に多孔質材層あるいは繊維質材層を積層して、これらを一体化し たことを前記課題の解決手段とした。 The wood decorative board of this invention has a thin metal plate as an intermediate layer, a single wood plate is laminated on one surface of the metal thin plate, and a porous material layer or a fibrous material layer is laminated on the other surface thereof to integrate them. Was used as a means for solving the above problems.
【０００７】[0007]
この考案の木質化粧板は上記の構成となっているので、金属薄板よる補強効果 が得られる。そしてこの木質化粧板をインサート成形に用いる際には、この木質 化粧板の多孔質層あるいは繊維質層に密着して合成樹脂を射出成形することによ って、溶融した合成樹脂が多孔質材の小孔内に、あるいは繊維質材の繊維間に侵 入して、十分なアンカー効果が得られる。したがって複合成形品の製造において 表面材と合成樹脂芯材との十分な接着強度が得られる。 Since the wooden decorative board of the present invention has the above-mentioned structure, the reinforcing effect by the thin metal plate can be obtained. When this wood decorative board is used for insert molding, the molten synthetic resin is made into a porous material by injecting the synthetic resin in close contact with the porous layer or fibrous layer of the wood decorative board. Sufficient anchoring effect can be obtained by penetrating into the small holes or between the fibers of the fibrous material. Therefore, sufficient adhesive strength between the surface material and the synthetic resin core material can be obtained in the production of the composite molded product.
【０００８】[0008]
以下、この考案を詳しく説明する。図１は本願考案の木質化粧板１の一例を示 すものであって、図中符号２は金属薄板、３は木質単板、４は多孔質材である。 この木質化粧板１は金属薄板２の一面上に木質単板３が、また他面上には多孔質 材４がそれぞれ接着剤によって積層一体化されている。この多孔質材４は単層の ものだけでなく、これを２層以上に積層して用いることもできる。 The invention will be described in detail below. FIG. 1 shows an example of a wood decorative board 1 of the present invention, in which reference numeral 2 is a thin metal plate, 3 is a wood single board, and 4 is a porous material. This wood decorative board 1 has a wood veneer 3 laminated on one surface of a thin metal plate 2 and a porous material 4 laminated on the other surface thereof by an adhesive agent. The porous material 4 is not limited to a single layer, but can be used by laminating two or more layers.
【０００９】 本願考案で用いられる金属薄板２としては、アルミニウム、鋼、 等の金属を０．０１〜０．５mm程度の厚さの薄板に形成したものを用いることが できる。この金属薄板２の厚さは、特に０．０５〜０．３mmの範囲とするのが好 ましい。ここで、この金属薄板２の厚さが０．０１mm未満では、これによって、 表面部の木質単板３を補強する効果が得られず、０．５mmを越えると剛性が高過 ぎる。しかしながら、必要に応じてこの厚さ以上の厚さの金属薄板４を使用する ことも可能である。また、この金属薄板２は、耐食性、接着性等を向上せしめる ために化成被膜処理を施したものが望ましい。As the metal thin plate 2 used in the present invention, a metal such as aluminum or steel formed into a thin plate having a thickness of about 0.01 to 0.5 mm can be used. The thickness of the thin metal plate 2 is preferably in the range of 0.05 to 0.3 mm. Here, if the thickness of the metal thin plate 2 is less than 0.01 mm, the effect of reinforcing the wood veneer 3 on the surface cannot be obtained, and if it exceeds 0.5 mm, the rigidity becomes too high. However, if necessary, it is possible to use the metal thin plate 4 having a thickness equal to or larger than this thickness. Further, it is desirable that the thin metal plate 2 be subjected to a chemical conversion coating treatment in order to improve the corrosion resistance, the adhesiveness and the like.
【００１０】 また、本願考案で用いられる木質単板３としては、任意の材質のものを用いる ことができるが、木目柄の美しいものを用いることが望ましい。また、その厚さ は０．１５〜０．５mmで、特に０．２mm程度のものが好ましい。ここで、この木 質単板３の厚さが０．１５mm未満では強度上の難点を生じ、０．５mmを越えると 、形状追従性が低下し、複雑な形状の成形品を成形するのが困難となる。また、 この厚さはこれらの範囲に限らず、多孔質材４の材質や厚さ等によって変えるこ とも可能である。The wood veneer 3 used in the present invention may be made of any material, but it is preferable to use a wood grain pattern that is beautiful. The thickness thereof is 0.15 to 0.5 mm, preferably about 0.2 mm. Here, if the thickness of the wood veneer 3 is less than 0.15 mm, a difficulty in strength occurs, and if it exceeds 0.5 mm, the shape following property is deteriorated, and a molded product having a complicated shape is formed. It will be difficult. Further, this thickness is not limited to these ranges and can be changed depending on the material and thickness of the porous material 4.
【００１１】 また、本願考案で用いられる多孔質材４としては、木質単板、発泡性樹脂板（ 連続気泡）等を用いることができ、その厚さは、木質化粧板１の形状追従性を低 下させない範囲で任意に設定することができる。例えば、木質単板を用いる場合 は上記木質単板と同様のものを用いるとができる。As the porous material 4 used in the present invention, a wood veneer, a foamable resin plate (open cells), or the like can be used, and the thickness of the porous veneer 4 has a shape conforming property of the wood decorative board 1. It can be set arbitrarily within the range where it is not lowered. For example, when a wood veneer is used, the same wood veneer as described above can be used.
【００１２】 これらの木質単板３、金属薄板２、多孔質材４は接着剤によって一体化されて 木質化粧板１を形成するが、ここで用いられる接着剤は特に限定されない。しか し、この木質化粧板１は合成樹脂をインサート成形する工程に供することができ るように、耐熱性の熱硬化型接着剤を用いて、加圧加熱接着するのが好ましい。The wood veneer 3, the metal thin plate 2, and the porous material 4 are integrated by an adhesive to form the wood decorative board 1, but the adhesive used here is not particularly limited. However, it is preferable that the wood decorative board 1 be pressure-heat bonded by using a heat-resistant thermosetting adhesive so that it can be subjected to the step of insert molding a synthetic resin.
【００１３】 このような木質化粧板１を表面材として用いて複合成形品をつくるには、図２ に示すように、例えば射出成形金型６内に木質化粧板１を配置し、合成樹脂を射 出すると、木質化粧板１は金型６の形状に沿って変形して所望の形状に成形され るとともに、この木質化粧板１と合成樹脂芯材７とが一体化された成形品が得ら れる。これを離型すると図３に示すような複合成形品８が得られる。ここで、図 ３中、符号９は塗装を示す。In order to make a composite molded article using such a wooden decorative board 1 as a surface material, as shown in FIG. 2, for example, the wooden decorative board 1 is placed in an injection molding die 6 and a synthetic resin is used. Upon ejection, the wooden decorative board 1 is deformed along the shape of the mold 6 to be molded into a desired shape, and a molded product in which the wooden decorative board 1 and the synthetic resin core material 7 are integrated is obtained. Be released. When this is released, a composite molded product 8 as shown in FIG. 3 is obtained. Here, in FIG. 3, reference numeral 9 indicates coating.
【００１４】 図４に示すように、この複合成形品８において合成樹脂芯材７は木質化粧板１ の多孔質材４と接している。そして図５に示すように多孔質材４の小孔４ａ内に 樹脂が侵入した状態となっている。このアンカー効果によって、木質化粧板１と 合成樹脂芯材７とが強固に接合されているので、これらが剥離することがない。 また、木質化粧板１の面に塗装９を施し、バフ研磨して鏡面仕上げする場合、研 磨熱によって境界の合成樹脂芯材７が軟化しても、金属薄板２が設けられている ので、その動きが表面にあらわれて細かい凹凸模様が発生することがない。 さらに、金属薄板２によって、水分の透過が遮断されるので、耐湿性がよく、 耐久性に富む製品が得られる。As shown in FIG. 4, in this composite molded article 8, the synthetic resin core material 7 is in contact with the porous material 4 of the wooden decorative board 1. Then, as shown in FIG. 5, the resin has entered the small holes 4a of the porous material 4. Due to the anchor effect, the wooden decorative board 1 and the synthetic resin core material 7 are firmly bonded to each other, so that they are not separated from each other. When the surface 9 of the wooden decorative board 1 is coated, buffed and mirror-finished, the thin metal plate 2 is provided even if the synthetic resin core material 7 at the boundary is softened by the polishing heat. The movement does not appear on the surface and a fine uneven pattern does not occur. Further, since the thin metal plate 2 blocks the permeation of water, a product having good moisture resistance and high durability can be obtained.
【００１５】 また本願考案において、多孔質材４に代えて繊維質材５を用いて木質化粧板１ を形成し、これをインサート成形に供しても同様の効果が得られる。ここで用い られる繊維質材５としては、不織布、布、紙、ガラス繊維マット等を用いること ができ、その厚さは、木質化粧板１の形状追従性を低下させない範囲で任意に設 定することができる。また、その目付は３０〜７０ｇ／ｍ2のものを好ましく用 いることができる。In the present invention, the same effect can be obtained by forming the wood decorative board 1 using the fibrous material 5 instead of the porous material 4 and subjecting it to insert molding. As the fibrous material 5 used here, non-woven fabric, cloth, paper, glass fiber mat or the like can be used, and the thickness thereof is arbitrarily set within a range that does not deteriorate the shape-following property of the wooden decorative board 1. be able to. Further, those having a basis weight of 30 to 70 g / m 2 can be preferably used.
