ドとして用いられる。[Detailed explanation of the idea] Conventionally, as a baseboard used for secondary processing as a base material for decorative boards such as overlay printing and painting, veneer was used for the top plate, core board, and back board of the baseboard. Plywood for the base board, honeycomb core of paper other than veneer, paper roll plywood, particle board, soft board, hard board, asbestos board, etc. for the core board, special plywood for the core material using veneer for the top and back boards, etc. is known to be used. Usually, a known decorative paper is pasted on the top surface of this plywood base plate and used as a decorative board.

Impregnating paperboard with phenolic resin, melamine resin, etc.
Laminated resin-impregnated paper laminates are known and are used in printed wiring board applications for electronic circuits.
(Paper laminates are known from Japanese Patent Publication No. 37-13505 and others.)Resin-impregnated paper laminates using conventional paperboards can be used in the longitudinal direction of the paperboards (in the direction of movement of the paper machine) when stacking multiple sheets of paperboards. Parallel paper direction (hereinafter abbreviated as MD) or transverse direction (paper direction perpendicular to the direction of paper machine movement, hereinafter referred to as MD)
It is common practice to align the paperboards in one direction only (abbreviated as CD) and attach them with resin adhesive.
しかしながら、このように積層された積層板
は、紙に方向性があるため、縦横の強度差が大き
く、また方向性によるカールも発生し易く、化粧
ボードの台板に使用しようとしても家具、建材用
としての適性は不充分であつた。 However, since the laminates laminated in this way have a directional paper, there is a large difference in strength between the vertical and horizontal directions, and curling is also likely to occur due to the directional nature. Its suitability for use was insufficient.
そこで本考案者等は、紙板を積層するに際し、
一の板紙のMDと他の板紙のMDとが互いに直交
するように積層する組合せが、積層板の層中に少
なくとも１組存在するようにして、縦横差が少
く、カールを改良した紙積層板を得ることに成功
した。 Therefore, the inventors of the present invention, when stacking paperboards,
A paper laminate that has a combination in which the MD of one paperboard and the MD of the other paperboard are laminated perpendicularly to each other, with at least one set in each layer of the laminate, resulting in less vertical and horizontal differences and improved curl. succeeded in obtaining.

た。 At the same time, in order to increase the overall strength, especially stiffness (rigidity) and stiffness of the laminate, as well as its water resistance, we made the paperboard an unprecedentedly strong size, making it suitable for furniture and building materials. It has also been found that the furniture and base plates of the present invention suitable for use in building materials can be obtained.

であるのに対し、本考案の板紙を積層して得られ
る紙積層板である点で異なる。 Laminating so that the MD of one paperboard and the MD of the other paperboard are perpendicular to each other means that when manufacturing plywood, several thinly peeled veneers of wood are stacked perpendicularly and then glued together. They share the same idea and the method of bonding them together to form a single board, but while veneer has the direction of the natural wood grain, MD and CD of paperboard have the direction of the pulp fibers produced as a result of papermaking. . Furthermore, the resulting board is different from plywood obtained by laminating veneer boards, in that it is a paper laminate board obtained by laminating the paperboards of the present invention.
本考案は家具、建材用台板に従来の合板に代え
て板紙を使用するものである。 The present invention uses paperboard instead of conventional plywood for furniture and building material baseboards.

であり、家具、建材用の積層板ではない。 In addition, Utility Model Publication No. 46-13928 discloses a laminate of at least two sheets of paper to which split fibers of a network structure are attached or inserted, and at least two of the papers are made of split fibers. A laminated paper is disclosed in which the directions intersect at an angle of 45 to 90 degrees, but the direction of split fibers attached to or drawn into the paper is not the flow direction of the paper itself, but the direction of split fibers attached to or drawn into the paper is 45 to 90 degrees. They differ in that they are stacked intersectingly at an angle of ~90°,
It is used for heavy bags, handbags, string, fusuma paper, shoji paper, etc., and is not used as a laminate for furniture or building materials.
次に本考案の家具、建材用台板の構成について
説明する。 Next, the structure of the base plate for furniture and building materials of the present invention will be explained.

層されていれば、本考案の実用新案登録請求の範
囲に含まれるということである。 First, the MD of one baseboard and the MD of another paperboard are laminated perpendicularly to each other so that there is at least one set in the layers of the baseboard. It is most preferable that all paperboard layers are laminated so that the paperboard direction combinations are orthogonal to each other, and if at least one set of paperboard layers is laminated orthogonally to each other, , it is included in the scope of the utility model registration claims of the present invention.

が好ましい。 The paperboard used in this invention is a strong-sized paperboard with high water resistance, unlike the paperboard used for ordinary paper laminates. (Ordinary paper laminates are porous without sizing, have good resin permeability, and have a large resin retention capacity.) Other characteristics include strong strength, paper quality, and uniform thickness. There is something
The PH of paper should be kept as close to neutral as possible, which is the same as paperboard for general paper laminates. Therefore, although the paperboard of the present invention has a strong size, it is preferable to use a neutral sizing agent or to use a cationic fixing agent instead of sulfuric acid as the fixing agent.
本考案の目的を達成するためには、従来にない
高いサイズ度を付与する必要がある。従来この種
の強サイズの板紙では、ステキヒト法サイズ度で
1000秒以上だつたものを、本考案では坪量

とした点に特徴がある。 In order to achieve the purpose of the present invention, it is necessary to provide an unprecedentedly high degree of size. Traditionally, this kind of strong size paperboard was manufactured using the Stekicht method.
In this invention, the basis weight is
The characteristic is that the time is 5000 seconds or more, preferably 10000 seconds or more at 680g/m 2 .
これにより、本考案の家具、建材用台板は耐水

接着剤等があげられる。 Next, as the adhesive for the paperboard used in this invention, most adhesives normally used for board laminates can be used, but since the laminate is made of highly water-resistant paperboard, the adhesive is also highly water-resistant. gender is necessary. Therefore, most synthetic adhesives can be used, except natural starch, casein, and animal adhesives, which are not preferred. For example, thermosetting adhesives such as amino resins such as urea and melamine, phenolic resins, xylene resins, furan resins, epoxy resins, polyisocyanate resins, and unsaturated polyester resins, and vinyl acetate-based, acrylic-based, polyvinyl acetal-based, and pyri Thermoplastic adhesives such as vinyl chloride, vinylidene chloride, polybutylene, ethylene copolymer, polyamide, thermoplastic polyester, polyacrylic acid, polyvinylpyrrolidene, polyacrylamide, polyvinyl ether, acrylic ester, vinyl acetate, and unsaturated Examples include water-soluble adhesives such as water-soluble polymers obtained by copolymerizing with acids, acrylamide, etc., synthetic rubber latex adhesives, and the like.

でも、本考案の加愛条件の方が緩い（本考案の方
が圧縮圧が低く、時間も短い。）ため、板紙が強
く圧縮を受けず、板紙本来の特性を発揮すること
ができるという特徴がある。 Compared to conventional paper laminates, the baseboards for furniture and building materials of the present invention have different absorbency of the paperboard used even if the same resin is used, and the amount of resin applied and impregnated is small. Even when molded using a hot press, the care conditions of the present invention are gentler (the compression pressure of the present invention is lower and the time is shorter), so the paperboard does not undergo strong compression and exhibits the original characteristics of the paperboard. It has the characteristic of being able to
すなわち、樹脂の大量塗布、高圧圧締による紙
積層板の硬化、脆化を防止し、板紙の厚さを生か
した腰の強さを生かすことができる。 In other words, it is possible to prevent the hardening and brittleness of the paper laminate due to the application of a large amount of resin and high-pressure pressing, and to take advantage of the stiffness that takes advantage of the thickness of the paperboard.
