本発明は、空隙率の高い基材を用いた皮膚に優しい医療用粘着テープまたはシートに関し、エマルション粘着剤の直写により製造コストが低減され、かつ貼付時の使用感が優れた粘着テープまたはシートに関する。 TECHNICAL FIELD The present invention relates to a skin-friendly medical pressure-sensitive adhesive tape or sheet using a substrate having a high porosity, and the pressure-sensitive adhesive tape or sheet has a reduced production cost due to direct copying of an emulsion pressure-sensitive adhesive and has an excellent feeling when used. About.
皮膚面に貼付して使用することを目的とする医療用粘着テープまたはシートは、一般に粘着剤層を介して適用すべき皮膚面に貼付使用される。この時に空隙率の高い基材を用いた粘着シートまたはテープを使用すると、肌触りが良好であり、貼付時の不快感が減少される。しかし、空隙率の高い基材を用いる場合は、空隙から粘着剤が裏抜けするのを防ぐため、転写により粘着剤を積層するのが一般的である。該転写による場合は、基材に粘着剤を積層するために予め剥離紙などのシートに粘着剤を積層し、該粘着剤が積層されたシートを基材に貼り合わせて転写させる操作が必要となる。しかし、基材に粘着剤が転写された後は、医療用粘着テープまたはシートの形態によっては該剥離紙などのシートが不要となる場合があり、該剥離紙などのシートは廃棄されるので製造コストがかかる。 A medical pressure-sensitive adhesive tape or sheet intended to be used by being attached to the skin surface is generally used by being applied to the skin surface to be applied via an adhesive layer. At this time, when an adhesive sheet or tape using a substrate having a high porosity is used, the touch is good and the discomfort at the time of application is reduced. However, in the case of using a substrate with a high porosity, it is common to laminate the adhesive by transfer in order to prevent the adhesive from slipping through the void. In the case of the transfer, an operation of laminating the pressure-sensitive adhesive on a sheet such as a release paper in advance to laminate the pressure-sensitive adhesive on the base material, and bonding the sheet on which the pressure-sensitive adhesive is laminated to the base material and transferring it is necessary. Become. However, after the adhesive is transferred to the base material, depending on the form of the medical adhesive tape or sheet, a sheet such as the release paper may be unnecessary, and the sheet such as the release paper is discarded and manufactured. costly.
製造コストの低減や環境面を考慮すると、基材に直接粘着剤を塗布する直写法により粘着剤を積層することが望まれる。しかし、空隙率の高い基材に直写で粘着剤を積層すると、基材の隙間に粘着剤が浸入し、粘着シートとしての機能を果たさなくなるという問題が生じる。また、粘着剤が基材の裏側に漏出するという裏抜けも生じうる。 In consideration of reduction in manufacturing cost and environmental aspects, it is desired to laminate the adhesive by a direct copy method in which the adhesive is directly applied to the substrate. However, when a pressure-sensitive adhesive is laminated directly on a base material having a high porosity, there is a problem that the pressure-sensitive adhesive enters a gap between the base materials and does not function as a pressure-sensitive adhesive sheet. In addition, there may be a case where the adhesive leaks out to the back side of the substrate.
基材の隙間への粘着剤の浸入を防止するために、基材に目止め処理を行うと空隙率が低下し、肌触りが悪くなる上に、基材端部での物理刺激によりかぶれを生じるなどの問題が考えられる。
また特許文献１には、貼付剤用支持体（基材）に関し、粘着剤の直写を行うために不織布とフィルムを組み合わせ、フィルム面への直写を可能とする方法が開示されている。しかし、フィルムを皮膚へ長時間貼付する場合、フィルムに通気性がないと蒸れが発生する。
In order to prevent the adhesive from entering the gaps in the base material, when the base material is subjected to a sealing treatment, the porosity is lowered and the touch is deteriorated, and rash is caused by physical stimulation at the end of the base material. Such a problem is considered.
Patent Document 1 discloses a method for enabling direct copying on a film surface by combining a non-woven fabric and a film in order to perform direct copying of an adhesive with respect to a support for a patch (base material). However, when the film is applied to the skin for a long time, stuffiness occurs if the film is not breathable.
従って、蒸れにくく、肌触りの良好な医療用粘着テープまたはシートであって、かつ製造コストが低減された医療用粘着テープまたはシートが望まれる。
本発明は、蒸れにくく、肌触りの良好な医療用粘着テープまたはシートであって、かつ製造コストが低減され、環境に優しい医療用粘着テープまたはシートを提供することを課題とする。 An object of the present invention is to provide a medical pressure-sensitive adhesive tape or sheet that is difficult to stuffy and has a good touch, and that is low in manufacturing cost and is environmentally friendly.
本発明者らは、上記の課題を解決すべく鋭意検討した結果、基材が積層され、該積層された基材に目止め処理を施すことにより、基材の隙間に粘着剤が浸入したり裏抜けするのを防止でき、かつ肌触りの良い基材を提供できることを見出した。さらに、粘着テープまたはシートのループ硬さを１５ｍＮ以上６０ｍＮ以下とすることで、優れた医療用粘着テープまたはシートを提供しうることを見出し、本発明を完成するに至った。 As a result of intensive studies to solve the above-mentioned problems, the present inventors have laminated a base material, and by applying a sealing treatment to the laminated base material, the pressure-sensitive adhesive enters the gap between the base materials. It has been found that it is possible to provide a base material that can be prevented from slipping through and has a good touch. Furthermore, it has been found that an excellent medical pressure-sensitive adhesive tape or sheet can be provided by setting the loop hardness of the pressure-sensitive adhesive tape or sheet to 15 mN or more and 60 mN or less, and the present invention has been completed.

When the coating amount is less than 10 g / m 2 , it is not possible to prevent the adhesive from coming through. On the other hand, when the coating amount is more than 50 g / m 2 , the skin feels poor and is easily stuffed, and it may be possible to cause rash due to physical irritation at the edge of the substrate. Therefore, a preferable coating amount is 10 to 35 g / m 2 , and more preferably 10 to 20 g / m 2 .
目止め処理を施さなければ、直写法によりエマルション粘着剤を直接基材に積層する際に、基材に粘着剤が浸入してしまったり、あるいは、エマルション粘着剤の裏抜けなどにより、医療用粘着テープまたはシートとして機能しなくなる場合がある。 If the sealing treatment is not applied, when the emulsion adhesive is directly laminated on the substrate by the direct copy method, the adhesive may penetrate into the substrate, or the emulsion adhesive may fall through, etc. May not function as a tape or sheet.
本発明において目止め剤塗布量は、目止め剤を塗布した基材１ｍ２の重量を測定し、以下の式により算出することができる。
目止め剤塗布量［ｇ／ｍ２］

Sealing agent application amount [g / m 2 ]
= Base weight coated with sealer [g / m 2] - substrate weight [g / m 2]
目止め剤については、特に限定されるものではないが、酢酸ビニル系樹脂、アクリル系樹脂、スチレン−ブタジエンゴム（ＳＢＲ）系、ロジン系樹脂等を用いることができる。溶剤系のものを用いても良いが、環境保護の観点からエマルション状の水系のものが望ましい。目止め処理の方法としては、目止め剤を基材に含浸させ、乾燥させるなど、一般的な方法を用いる事ができる。 The sealant is not particularly limited, and vinyl acetate resin, acrylic resin, styrene-butadiene rubber (SBR), rosin resin, and the like can be used. A solvent-based one may be used, but an emulsion-based water-based one is desirable from the viewpoint of environmental protection. As a method for the sealing treatment, a general method such as impregnating a sealing agent into a base material and drying can be used.
本発明の医療用粘着テープまたはシートは、積層された基材の少なくとも片面に、粘着剤層を有する。粘着剤層は、目止め処理された基材の側に直写され、積層されているのが好適である。基材が目止め処理されていることにより、粘着剤の浸入や裏抜けを防止することができる。 The medical pressure-sensitive adhesive tape or sheet of the present invention has a pressure-sensitive adhesive layer on at least one surface of the laminated base material. The pressure-sensitive adhesive layer is preferably directly copied and laminated on the side of the base material subjected to the sealing treatment. Since the base material is subjected to a sealing treatment, it is possible to prevent the adhesive from entering and back through.
本発明の医療用粘着テープまたはシートの形態は、特に限定されないが、例えばロール状粘着部材のように、剥離紙を伴わないものが好適である。ロール状の粘着テープまたはシートは剥離紙を必要としないため、粘着剤の直写法での積層方法による製造コストの低減効果が大きいからである。ロール状の粘着テープまたはシートとする場合には、基材の粘着剤層とは反対側の面に背面処理を施す必要がある。背面処理剤としては、フッ素系剥離剤や長鎖アルキル系剥離剤、シリコーン系剥離剤またはその混合系等を用いることができる。背面処理の方法については一般的な方法を用いる事ができる。 Although the form of the medical adhesive tape or sheet | seat of this invention is not specifically limited, For example, the thing without a release paper like a roll-shaped adhesive member is suitable. This is because a roll-like adhesive tape or sheet does not require a release paper, and therefore has a great effect of reducing the manufacturing cost by the lamination method using the direct-copying method of the adhesive. In the case of a roll-like pressure-sensitive adhesive tape or sheet, it is necessary to perform a back surface treatment on the surface of the substrate opposite to the pressure-sensitive adhesive layer. As the back surface treatment agent, a fluorine-based release agent, a long-chain alkyl release agent, a silicone-based release agent, or a mixed system thereof can be used. A general method can be used for the back surface processing.
