本発明は、金属板などの表面保護フィルムに関し、さら
に詳しくは、空気の抱き込みによるシワの発生が防止さ
れた表面保護フィルムに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a surface protection film for metal plates, etc., and more particularly to a surface protection film that is prevented from forming wrinkles due to air entrapment.
１土立五ｌ
ステンレス板、アルミニウム板、カラー鋼板などの金属
板または合成樹脂板等の加工時、切断時あるいは運搬時
に、これらの表面が汚れたり、傷が付けられたりするの
を防止するために、表面保護フィルムが貼付される。1. To prevent the surface of metal plates such as stainless steel plates, aluminum plates, and colored steel plates, or synthetic resin plates from getting dirty or scratched during processing, cutting, or transportation. A surface protection film is attached to the surface.
この表面保護フィルムは、通常、ポリエチレン、ポリプ
ロピレン、ポリ塩化ビニルなどの熱可塑性樹脂からなる
基材層の片面に、天然ゴム、合成ゴム、熱可塑性エラス
トマー、エチレン−酢酸ビニル共重合体、アクリル系樹
脂など各種のポリマーを主成分とする粘着剤層が設けら
れた構成を有している。This surface protection film usually has a base layer made of thermoplastic resin such as polyethylene, polypropylene, or polyvinyl chloride, and one side of the base layer is made of natural rubber, synthetic rubber, thermoplastic elastomer, ethylene-vinyl acetate copolymer, or acrylic resin. It has a structure provided with an adhesive layer containing various polymers such as the following as a main component.
ところで、鋼板を製造する場合、表面保護フィルムを貼
付した長尺の鋼板は、−旦、コイル状に巻き取ってから
、次の工程では、巻き戻して所定の大きさの板に切断す
る。By the way, when manufacturing a steel plate, a long steel plate with a surface protection film attached is first wound into a coil shape, and then in the next step, it is unwound and cut into plates of a predetermined size.
すなわち、製造された長尺の鋼板は、研磨や塗装、ラミ
ネートなどの加工工程を経て、コイル状に巻かれるが、
その前段階で表面保護フィルムが貼付される。ところが
、表面保護フィルムを貼付した長尺の鋼板をコイル巻き
としたときに、該フィルムと鋼板表面との間に隙間を生
じることがあり、フィルムが浮く状態となる。In other words, the manufactured long steel plate is wound into a coil after undergoing processing steps such as polishing, painting, and laminating.
Before that, a surface protection film is applied. However, when a long steel plate to which a surface protection film is attached is wound into a coil, a gap may be created between the film and the surface of the steel plate, causing the film to float.
次に、コイル巻きにされた長尺の鋼板は、巻き戻してレ
ベラー工程を経た後、所定の大きさの板状に切断する。Next, the coil-wound long steel plate is unwound and subjected to a leveler process, and then cut into plates of a predetermined size.
このレベラー工程では、通常、対もしくは複数対のピン
チロールの間に巻き戻した鋼板を通し、ピンチ圧をかけ

ルに押しつぶされてしまう。そして、板状に切断されて
出来上がった鋼板には、シワの入ったフィルムが貼付さ
れていることになる。In this leveler process, the unwound steel plate is usually passed between a pair or multiple pairs of pinch rolls and pinch pressure is applied to make it into a straight flat plate. At this time, as mentioned above, if there is a gap between the surface protection film and the steel plate and the film is floating, the pinch roll part of the leveler will cause the air trapped between the film and the steel plate to have a place to escape. This causes wrinkles in the film on the steel plate, which ends up being crushed by the leveler's pinch rolls. Then, a wrinkled film is attached to the steel plate that is cut into plate shapes.
このようなシワの入ったフィルムが貼付されている鋼板
は、美観が損なわれ、商品価値が低下するだけではなく
、塗装鋼板などで塗装面が比較的柔らかい場合などには
、フィルムのシワの折り重なりの部分が塗装面に圧痕と
して残ることもある。Steel plates to which such wrinkled films are attached not only impair their aesthetic appearance and reduce their commercial value, but also cause the wrinkles in the film to fold when the painted surface is relatively soft, such as painted steel plates. The overlap may remain as an impression on the painted surface.
しかしながら、従来の表面保護フィルムでは、このよう
なシワの発生を防ぐことは出来なかった。However, conventional surface protection films have not been able to prevent the occurrence of such wrinkles.

護フィルムを提供することにある。An object of the present invention is to provide a surface protection film that does not entrap air or cause wrinkles.
また、本発明の目的は、特に、鋼板保護用に適用した場
合に、レベラ一部でシワがはいらない表面保護フィルム
を提供することにある。Another object of the present invention is to provide a surface protection film that does not cause wrinkles on a portion of the leveler, especially when applied to protect a steel plate.
本発明者らは、前記従来技術の問題点を克服するために

ラー工程を経ても、空気の抱き込みやシワの発生のない
ことを見出し、その知見に基づいて本発明を完成するに
至った。As a result of intensive research to overcome the problems of the prior art, the inventors of the present invention have found that a surface protection film can be attached to a steel plate by providing through holes large enough to allow gas such as air to pass through the surface protection film. The inventors discovered that even after coiling, unwinding, and leveling, there is no air entrapment or wrinkles, and based on this knowledge, the present invention was completed.

いることを特徴とする表面保護フィルムが提供される。(According to the present invention, in a surface protection film in which an adhesive layer is formed on one side of a base layer made of a thermoplastic resin, through-holes through which gas permeates are provided in the film. Provided is a surface protection film characterized by:
以下、本発明について詳述する。The present invention will be explained in detail below.
本発明が対象とする表面保護フィルムは、熱可塑性樹脂
からなる基材層の片面に粘着剤層が形成された表面保護
フィルムであれば、特に限定されない。The surface protection film targeted by the present invention is not particularly limited as long as it is a surface protection film in which an adhesive layer is formed on one side of a base layer made of a thermoplastic resin.
貫通孔は、第１図に示すように、基材層ｌおよび粘着剤

だし、あまり孔が大きすぎると、表面保護の機能が損な
われるので、例えば、貫通孔の形状が円形である場合に
は、通常、その上限は直径５０ｍｍ程度である。The through-hole has a shape that penetrates both the base material layer 1 and the adhesive layer 2, as shown in FIG. The size and shape of the through hole 3 may be any size as long as it allows gas to pass therethrough. However, if the hole is too large, the surface protection function will be impaired, so if the through hole is circular in shape, the upper limit is usually about 50 mm in diameter.
また、貫通孔は、フィルム面上に必ずしも規則正しく配
列されている必要はないが、隣接する孔との間隔は１ｍ
ｍ以上とすることが望ましい。孔どうしの間隔が１ｍｍ
未満の場合、フィルムを貼り付ける時に、テンション（

し、フィルムが破れたり、切れるといった現象をおこす
ので、好ましくない。孔と孔との間隔の上限は特に限定
されないが、あまり間隔が大き過ぎると、レベラ一部で
充分空気が抜けないので、通常、５００ｍｍ程度までと
することが好ましい。In addition, the through holes do not necessarily have to be arranged regularly on the film surface, but the distance between adjacent holes is 1 m.
It is desirable to set it to m or more. The distance between holes is 1mm
If the tension is less than
If force is applied to the film, that part acts like a perforation, causing the film to tear or cut, which is not desirable. The upper limit of the distance between the holes is not particularly limited, but if the distance is too large, air will not be able to escape sufficiently from a portion of the leveler, so it is usually preferably up to about 500 mm.
貫通孔は、パンチャー等の適宜の孔あけ機を用いればよ
い。The through-hole may be formed using an appropriate hole-drilling machine such as a puncher.
このように気体の透過する貫通孔を設けであるので、本

たまることもなく、その結果シワも生じない。Since the through-holes for gas permeation are provided in this way, the surface protection film of the present invention can be applied to a long steel plate and then
Even if there is a gap between the film and the steel plate due to coil winding, air escapes through the holes, so air will not accumulate in a part of the leveler, and as a result, no wrinkles will occur.

直にした後、フィルムのシワの有無を観察した。[Examples 1 to 3, Comparative Example 1] A surface protection film in which through-holes having the sizes and hole spacing shown in Table 1 were provided on a steel plate with a diameter of 100,100 mm, a length of 1,500 mm, and a thickness of 0.2 mm (Tanezu Chemical Industry Co., Ltd.). After attaching a protective tape (manufactured by Manufacturer Co., Ltd., #624D107), the film was artificially lifted by bending it to R=500 mm with the attached side facing inside. The sample was passed through a leveler using three pairs of pinch rolls (pinch pressure 5 kg/cIT12) to straighten it, and then the presence or absence of wrinkles in the film was observed.
比較のために、従来の孔なしの表面保護フィルムを用い
て同様の処理を行なってフィルムのシワの発生の有無を
観察した。For comparison, a conventional surface protection film without holes was subjected to the same treatment and the presence or absence of wrinkles in the film was observed.

際フィルムと鋼板の間に抱き込まれた空気がその孔より
抜け、シワを生じないことがわかる。As is clear from Table 1, by providing through holes in the surface protection film (Examples 1 to 3), the air trapped between the film and the steel plate when passing through the leveler escapes through the holes, eliminating wrinkles. It turns out that this does not occur.

た後にシワの発生が見られ、また、レベラー工程の後に
もフィルムと鋼板との間に空気が残存していた。On the other hand, when using a conventional surface protection film that does not have through-holes (Comparative Example 1), wrinkles were observed after passing it through the leveler, and the film remained intact even after the leveler process. Air remained between the steel plate and the steel plate.
