Description

本発明は浮き彫り図(エンボス図)のある紙に関し,更に詳しくは三層の構造からなる合成紙(Synthetic paper)を改良した、エンボス装置(Embossing device)にてエンボスしてなるエンボス合成紙に関する。   The present invention relates to a paper having a relief drawing (embossed drawing), and more particularly to an embossed synthetic paper embossed by an embossing device, which is an improved synthetic paper having a three-layer structure.

書き写し,印刷或いは包装用材として、現在最も大量に使用される資材の典型的なものの一つである紙は,各種の植物繊維又は合成繊維とを合成したものからなるものである。また、このような構造を持つ紙の代わりに紙状の外観及び機能を有するプラスチックフィルム(合成紙)を用いることは,古くから提案され実用化されている。 Paper, which is one of the typical materials used in large quantities as a material for copying, printing or packaging, is composed of various plant fibers or synthetic fibers. In addition, the use of a plastic film (synthetic paper) having a paper-like appearance and function instead of paper having such a structure has been proposed and put into practical use.

このプラスチックフィルムの紙化技術の基本的なものをまとめて示せば、プラスチック自身の表面を;(1)紙状化にするため物理処理又は化学処理を行なう方法,(2)充てん剤配合プラスチックをフィルム状に形成するものからなる方法と,(3)表面に別に紙状層を設けるものとからなる方法等がある。だがこれらの方法で出来た合成紙(ポリオレフイン又はPE,ポリプロピレン)はそれぞれ何らかの欠点を有している。   The basics of this plastic film papermaking technology can be summarized as follows: (1) a method of physical or chemical treatment to make paper, (2) a filler-containing plastic There are a method comprising a film-like method, and (3) a method comprising separately providing a paper-like layer on the surface. However, the synthetic paper (polyolefin or PE, polypropylene) made by these methods has some drawbacks.

アメリカ特許5.536,468号は、単層のポリマーシートに透かしを入れる印刷技術に係る方法を開示しており、この方法は、互いに隣接したローラーの間にポリマーシートを通過させることであり、少なくとも1つのローラーは、通過するシートに凹みを形成するために凹模様および/または凸模様を有し、シートの凹みは、ローラーの凹模様および/または凸模様に対応し、シートは、シートを伸張させることによって配向させる。凹みがあり、配向させたシートは、模様の凸部に対応する暗色領域と、模様の凹部に対応する明色領域を有する。 U.S. Pat. No. 5,536,468 discloses a method according to a printing technique for watermarking a single layer polymer sheet, the method being to pass the polymer sheet between rollers adjacent to each other, at least 1 One roller has a concave and / or convex pattern to form a recess in the passing sheet, the sheet recess corresponds to the concave and / or convex pattern of the roller, and the sheet stretches the sheet Orientation. The sheet having a dent and oriented has a dark color region corresponding to the convex portion of the pattern and a light color region corresponding to the concave portion of the pattern.

また、アメリカ特許第6,364,988B1(即ち特開2000-211008)は本願出願人が1999年9月13日に出願し、2002年4月2日に特許されたものである。この発明は三層共押出にてそれぞれ1台のフィーダ付ツインスクリユー(Twin Screw)の主押出機と,2台のフィーダ付ツインスクリユーの副押出機から押出されたポリプロピレン樹脂と無機物の押出物を合わせ,1つのT-ダイヘッド(T-dies head)を経て紙状層又は樹脂層/発砲中間層/紙状層又は樹脂層の三層シート(Sheet)となし,さらに冷却成形,二軸延伸(Biaxial orientation),コロナ(Corone)処理,巻き取り等を施して合成紙を作製したものである。 US Pat. No. 6,364,988B1 (that is, Japanese Patent Application Laid-Open No. 2000-211008) was filed on September 13, 1999 by the present applicant and patented on April 2, 2002. This invention is an extrusion of polypropylene resin and inorganic material extruded from one twin screw main extruder and two twin screw sub-extruders with feeders by three-layer coextrusion. Combining the objects, the sheet-like layer or resin layer / foaming intermediate layer / paper-like layer or resin layer three-layer sheet (sheet) is passed through one T-dies head, and it is further cooled and biaxial. This is a synthetic paper that has been subjected to biaxial orientation, corone treatment, and winding.

また、特公昭46-40704,特開昭 56-118437,特開昭56-141339,及び特開平3-87255の合成紙は書き写し,印刷用,包装用材及び各種の紙用途に使用することが出来る。しかし、容易,且つ簡単に浮き彫り模樣(Emboss patterns)を合成紙上にエンボスして浮き彫り模様のある合成にすることは困難で難しかった。   The synthetic paper described in JP-B-46-40704, JP-A-56-118437, JP-A-56-141339, and JP-A-3-87255 can be used for copying, printing, packaging materials and various paper applications. . However, it has been difficult and difficult to easily and easily emboss emboss patterns on synthetic paper to make embossed patterns.

さらに、従来の技術では、3層の合成紙を、一枚(単層)のプラスチックフィルム或いは自然繊維からなる造紙の様に合成紙上にエンボスして浮き彫り模様のなる合成にすることは困難で難しかった。たとえエンボスはできてもエンボス模様の安定性が悪く使用性がないものであったからである。   Furthermore, with the conventional technology, it is difficult and difficult to synthesize a three-layer synthetic paper into a synthetic pattern embossed on a synthetic paper like a single (single-layer) plastic film or paper made of natural fibers. It was. This is because even if embossing was possible, the stability of the embossed pattern was poor and there was no usability.

上記技術の困難性と安定性の向上の必要性,周知エンボス装置を使用することが出来ないことなどに鑑み,本願発明者等は多年の現場経験,実験と検討の結果,周知エンボス装置の型押しロールを少なくともショアA硬さ(ショアA硬度)が60〜90のゴム製型押しロールに入れ替え,合成紙は先に65℃〜最高160℃(より良きは115℃)で予熱して,毎分15〜18メートルの速度で型押しロールとエンボスロールの間を通過してエンボスし,7℃ 左右のドラム(1組)で急速冷却して浮き彫り模様を合成紙上に定着成形することにより、天然繊維からなる紙,例えば帆布(canvas)又は美術紙(art paper)と同様なエンボス合成紙を得ること出来ることを見出し,本発明を完成した。   In view of the difficulty of the above technology and the need for improved stability and the inability to use known embossing devices, the inventors of the present application have made many years of experience in the field, as well as experiments and examinations, Replace the pressing roll with a rubber stamping roll with at least Shore A hardness (Shore A hardness) of 60 to 90, and preheat the synthetic paper at 65 ° C up to 160 ° C (better 115 ° C). Embossed by passing between the embossing roll and embossing roll at a speed of 15 to 18 meters per minute, and then rapidly cooling with 7 ° C left and right drums (one set) to fix the embossed pattern onto the synthetic paper. It was found that embossed synthetic paper similar to paper made of fibers, such as canvas or art paper, can be obtained, and the present invention has been completed.

図1は本発明の三層構造のエンボス合成紙の構成図で,11と13は副層,12が主層,14はエンボス模様又は図案である。
三層構造のエンボス合成紙(3層共押出二軸配向ポリプロピレンパール合成紙)は、3層構造、たとえば、絹目紙シート層/発泡中間層/接着層もしくは光沢紙シート層/発泡中間層/接着層または樹脂層/樹脂層/接着層であり、接着層の材料は、PP、LPPEまたはHDPEである。
Hereinafter, embodiments for carrying out the present invention will be described with reference to the drawings.
FIG. 1 is a configuration diagram of a three-layer embossed synthetic paper according to the present invention, in which 11 and 13 are sub-layers, 12 is a main layer, and 14 is an embossed pattern or design.
Three-layer embossed synthetic paper (three-layer coextrusion biaxially oriented polypropylene pearl synthetic paper) has a three-layer structure, for example, silk paper sheet layer / foamed intermediate layer / adhesive layer or glossy paper sheet layer / foamed intermediate layer / Adhesive layer or resin layer / resin layer / adhesive layer, and the material of the adhesive layer is PP, LPPE or HDPE.

図2は、3層構造の二軸配向ポリプロピレンパール合成紙の製造工程を示す図である。符号21は、合成紙加工用の副投入ホッパーを備える抽出可能な二軸押出装置を示す。押出装置21には、主投入ホッパーを備える1つの第1の抽出可能な二軸押出機211と、副投入ホッパーを備える2つの第2の抽出可能な二軸副押出機213a、213bとが含まれる。加工温度は、製品の樹脂組成物の原料、MFI、結晶度、製造速度および厚さによって異なる。
材料の押出成形後、冷却成形ドラム22によって冷却工程を実施して高温の3層共押出材料を冷却する。冷却成形ドラムには、水冷装置または空冷装置を導入することが可能である。この工程で冷却温度を制御することはかなり重要であり、次の工程を成功裏に導く。
さらに、冷却工程によって成形される材料は、縦方向延伸装置23(長手方向配向装置)に投入して長手方向配向処理を実施し、特定の予熱温度に設定して材料を軟化させる。次に、高速配向と低速配向との2つの処理で配向させ、長手方向の機械的強度を増大させ、焼き戻して形成する。
次に、長手方向配向装置によって形成された材料は、横方向延伸装置24(横手方向配向装置)に投入する。長手方向配向装置によって形成された薄手材料は、(紙シートの厚さおよび製造速度に応じた)特定の温度で予熱して軟化する。次に、横手方向に配向させ、最終的には焼き戻して形成してパール合成紙の寸法安定性を増大させる。
その後、印刷、コーティング、接着、ラミネート加工などに使用される紙シートおよび膜の表面の物理的特性を改善するために、コロナ放電処理加工にコロナ放電処理装置25を使用する。単相電力または二相電力による加工には、特定の高周波放電装置を使用し、特定の湿度で特定の引張速度を得る。

FIG. 2 is a diagram showing a manufacturing process of biaxially oriented polypropylene pearl synthetic paper having a three-layer structure. The code | symbol 21 shows the biaxial extrusion apparatus which can be extracted provided with the sub input hopper for synthetic paper processing. The extrusion apparatus 21 includes one first extractable twin-screw extruder 211 having a main charging hopper and two second extractable twin-screw sub-extruders 213a and 213b having a sub-charging hopper. It is. The processing temperature varies depending on the raw material, MFI, crystallinity, production rate and thickness of the resin composition of the product.
After extrusion of the material, a cooling step is performed by the cooling molding drum 22 to cool the hot three-layer coextrusion material. A water cooling device or an air cooling device can be introduced into the cooling molding drum. Controlling the cooling temperature in this step is quite important and leads to the next step successfully.
Further, the material formed by the cooling process is put into a longitudinal stretching device 23 (longitudinal orientation device) and subjected to a longitudinal orientation treatment, and is set to a specific preheating temperature to soften the material. Next, it is oriented by two treatments of high-speed orientation and low-speed orientation, increasing the mechanical strength in the longitudinal direction, and tempering to form.
Next, the material formed by the longitudinal direction aligning device is put into the transverse stretching device 24 (lateral direction aligning device). The thin material formed by the longitudinal orientation device is preheated and softened at a specific temperature (depending on the thickness of the paper sheet and the production rate). Next, it is oriented in the transverse direction and finally formed by tempering to increase the dimensional stability of the pearl synthetic paper.
Thereafter, the corona discharge treatment apparatus 25 is used for corona discharge treatment processing in order to improve the physical properties of the surface of the paper sheet and film used for printing, coating, adhesion, laminating and the like. For processing by single-phase power or two-phase power, a specific high-frequency discharge device is used, and a specific tensile speed is obtained at a specific humidity.
Finally, after forming by the winder 26 and corona discharge treatment, a synthetic paper product can be formed by slitting, cutting or packing a piece of paper as necessary.

図3は本発明が改良したエンボス装置の構成概略図である。この装置は;
(1)少なくともショアA硬さが60〜90を有するゴム製型押しロール35と、ロールの表面に浮き彫り模様の型があり冷却設備を有するエンボスロール36からなる一組のエンボス設備と;

(3)最高160℃,好ましくは115℃にて加熱を行う赤外線加熱30と:
(4)好ましくは7℃で冷却を行う、左右一組の冷却ドラム31と,からなる。(合成紙は矢印16の方向に流れる)。
上記"冷却設備を有するエンボスロール"の記載に関して、図3にはその冷却設備を表示していないが、事実上冷却水にてエンボスロールを冷却するものであり、エンボス加工中に、エンボスロール36とゴム製型押しロール35とを同調させて同時に冷却できる。
合成紙のエンボス模様深度を0.2μm〜1000μmに限定したのは,このエンボスの深さにより合成紙がゴム製型押しロール35とエンボスロール36との間を通りエンボスすることが出来るからであり,必ずしもこの深さに限らず冷却定型してエンボス合成紙となるものであれば良い。
FIG. 3 is a schematic configuration diagram of an embossing device improved by the present invention. This device is;
(1) a set of embossing equipment comprising a rubber embossing roll 35 having a Shore A hardness of 60 to 90 and an embossing roll 36 having a relief pattern on the surface of the roll and having cooling equipment;
(2) a preheating roll 32 for preheating and a quartz electric oven 33 arranged with a certain gap on the side of the preheating roll;
(3) Infrared heating 30 for heating up to 160 ° C, preferably 115 ° C:
(4) It comprises a pair of left and right cooling drums 31 that are preferably cooled at 7 ° C. (Synthetic paper flows in the direction of arrow 16).
Although the cooling equipment is not shown in FIG. 3 regarding the above description of “embossing roll having cooling equipment”, the embossing roll 36 is effectively cooled with cooling water. And the rubber embossing roll 35 can be synchronized and cooled at the same time.
The embossed pattern depth of the synthetic paper was limited to 0.2 μm to 1000 μm because the embossed depth allows the synthetic paper to be embossed between the rubber embossing roll 35 and the embossing roll 36. The embossed synthetic paper is not necessarily limited to this depth as long as it is cooled to form an embossed synthetic paper.
