造方法に関する。[Detailed Description of the Invention] The present invention relates to a method for manufacturing decorative plywood, and more specifically,
When manufacturing plywood by stacking multiple veneers, a decorative material impregnated with thermosetting horizontal IIFf is placed on the surface of the laminated veneer after cold pressing is completed, and the two pieces are heat-pressed and formed into plywood. At the same time, the present invention relates to a method for producing decorative plywood, which is characterized in that a decorative material of thermosetting resin is primarily applied to the surface of the plywood by thermocompression bonding.

いる。Conventionally, decorative plywood is made by using a plywood that has been formed by heating and pressing as a base plate, placing various decorative materials on the surface, and then bonding them together by secondarily applying heat and pressure. .

。1. However, in the conventional decorative plywood manufacturing method described above, the thermosetting resin-impregnated paper placed on the plywood surface is secondarily heat-pressed, which consumes the same or more thermal energy than the plywood manufacturing process. Since the plywood surface has a certain hardness, the depth of the uneven portion is naturally limited even when secondary processing of an uneven pattern by embossing is applied.

を現実可能にしたものである。Therefore, in order to solve the above-mentioned disadvantages of the conventional method, the present invention provides a method for manufacturing plywood by stacking several veneers in a cross-layered manner and crimping them. A decorative material impregnated with a thermosetting resin is placed on the plywood, and the two pieces are bonded under heat to form plywood. At the same time, the decorative material is applied to the surface of the plywood, which makes surface processing a reality. This is what I did.

に化粧材を付与することを特徴とするものである。That is, the method for manufacturing decorative plywood of the present invention uses melamine,
Manufacture of plywood using decorative paper coated with or impregnated with various thermosetting resins such as diallyl phthalate, polyester, and pheno-μ resin, or chemically made of precious wood veneer (hereinafter referred to as decorative material containing thermosetting resin). Immediately after the cold pressing step, which is a pre-forming step by hot pressing, is placed on one or both surfaces of the laminated veneer, and a shaping plate having a smooth or uneven pattern is applied to both surfaces. The plywood is molded and a decorative material is applied to the surface of the plywood at the same time as the plywood is formed by bringing them into contact with each other and heat-pressing them under conditions of, for example, 180 DEG C. to 150 DEG C. and 10 to 16 kti/cd.

化粧合板を得ることができる。In particular, when giving a deep uneven pattern to the plywood surface by embossing, use a comparatively soft material such as parts wood from Ny Pryten Island at the b-1 position in Figures 1 and 2. By using European quality veneer, it is possible to obtain decorative plywood with an uneven pattern that has depth and three-dimensionality that cannot be obtained by the conventional method of manufacturing decorative plywood using secondary heating and pressing.

る熱硬化性樹脂含有の化粧紙を省略することができる。On the other hand, when the resin layer of the decorative material applied to the surface is thin or the amount of resin contained is small, the surface thickness of the plywood veneer structure is 1.5 to 2. 0
By using Aviton veneer from Kalimantan, which has a thickness of 2.1 x ~ 2.8 yen, heat shrinkage is reduced and the front and back surfaces are balanced, so the thermosetting resin-containing material applied to the back side is Decorative paper can be omitted.

従来の化粧合板の製造方法のように二次的に加熱加圧す
る方法ではなく、いわゆるホット−ホット方式といわれ
る加熱加圧後に冷却を必要としない方法であるので短時
間に化粧合板を製造することができる。In this way, placing a decorative layer containing a thermosetting resin on only one surface of the plywood and applying a decorative surface at the same time as the plywood is formed is not possible in conventional plywood manufacturing methods, where the front and back sides are symmetrical. It is a decorative plywood that cannot be obtained at all, and it is produced using a method called the so-called hot-hot method that does not require cooling after heating and pressing, rather than using a secondary heating and pressing method like the conventional manufacturing method for decorative plywood. Therefore, decorative plywood can be manufactured in a short time.
なお、本発明の化粧合板の製造方法によれば合板の厚さ
１χ当り、加熱加圧して成形するに要する時間は約６０
秒というきわめて短時間である。In addition, according to the method for manufacturing decorative plywood of the present invention, the time required to heat and pressurize and shape the plywood per 1χ of thickness is approximately 60 minutes.
It is an extremely short time of seconds.
したがって、たとえば８χ厚さの合板表面に熱硬化性樹
脂含有の化粧材を熱圧着し合板を成形するに要する時間
は約１８０秒となる。Therefore, for example, it takes about 180 seconds to thermocompress a decorative material containing a thermosetting resin onto the surface of a plywood sheet having a thickness of 8.chi. to form the plywood sheet.
以上の説明の通り、本発明によれば合板の成形と同時に
その表面に熱硬化性樹脂含有の化粧材をきわめて短時間
内に熱圧着することができる。As explained above, according to the present invention, a decorative material containing a thermosetting resin can be thermocompression bonded to the surface of plywood in an extremely short time at the same time as the plywood is formed.
