従来、接着シートと被着体の被着面との接着界面に気泡が形成されないようにそれらを貼付する際には、接着シートおよび/または被着体を折り曲げて空気を追い出すように徐々に貼付したり、真空雰囲気下で貼付したりしている。
一方、被着体に貼付した後、接着界面の空気を抜くことができる易貼付性粘着シート(接着シート)が知られている(例えば、特許文献1参照)。
この接着シートは、剥離シートを用いて製造され、複数の球面状凸部が設けられ、隣接する凸部間に空気流通経路が形成されてなる粘着剤層(接着剤層)を有し、被着体に貼付した後に接着界面の空気を当該空気流通経路を介して逃がすことで、当該接着界面に気泡が形成されないようにしている。
Conventionally, when affixing them so that no bubbles are formed at the adhesive interface between the adhesive sheet and the adherend surface of the adherend, the adhesive sheet and / or adherend are bent and gradually stuck to expel air. Or affixed in a vacuum atmosphere.
On the other hand, an easy-adhesive pressure-sensitive adhesive sheet (adhesive sheet) that can release air at the adhesion interface after being attached to an adherend is known (see, for example, Patent Document 1).
This adhesive sheet is manufactured using a release sheet, and has a pressure-sensitive adhesive layer (adhesive layer) in which a plurality of spherical convex portions are provided and an air flow path is formed between adjacent convex portions. Air bubbles on the adhesion interface are allowed to escape through the air flow path after being attached to the adherend, so that bubbles are not formed on the adhesion interface.
しかしながら、特許文献1に記載されたような従来の剥離シートを用いて製造された接着シートでは、当該接着シートを被着体に貼付する動作の後、接着界面の空気を追い出すための動作が要求され、2つの動作が必要であるという不都合がある。 However, an adhesive sheet manufactured using a conventional release sheet as described in Patent Document 1 requires an operation for expelling air at the adhesive interface after an operation of attaching the adhesive sheet to an adherend. There is a disadvantage that two operations are necessary.
本発明の目的は、簡単に被着体との間に気泡が形成されないように貼付することができる接着シートを製造可能な剥離シートを提供することにある。 The objective of this invention is providing the peeling sheet which can manufacture the adhesive sheet which can be stuck so that a bubble may not be easily formed between to-be-adhered bodies.

At any position apart from the one point deepest part, the first point deepest part side has a first recess provided deeper than the outer edge side, and the first recess can make point contact with the adherend. A configuration is adopted in which one first vertex is provided on the adhesive layer of one adhesive sheet so as to be formed.
また、本発明の他の剥離シートは、接着シートに一方の当接面が仮着される剥離シートにおいて、前記一方の当接面は、線状の1の最深部である第1線状最深部から離間したいずれの位置においても当該第1線状最深部側が外縁側に比べて深く設けられた第1凹部を有し、前記第1凹部は、被着体に線接触可能な1の第1頂線を1の接着シートの接着剤層に形成可能に設けられている、という構成を採用している。 Another release sheet of the present invention is a release sheet in which one contact surface is temporarily attached to an adhesive sheet, wherein the one contact surface is a first linear deepest portion that is a linear deepest portion. The first linear deepest portion side has a first concave portion provided deeper than the outer edge side at any position separated from the portion, and the first concave portion is a first first contactable to the adherend. A configuration is adopted in which one top line is provided so as to be formed on the adhesive layer of one adhesive sheet.
この際、本発明の剥離シートでは、前記一方の当接面の反対側に位置する他方の当接面には、点状の最深部である第2点状最深部が設けられた第2凹部が設けられ、前記第2凹部は、被着体に点接触可能な第2頂点を前記接着シートとは別の1の接着シートの接着剤層に形成可能に設けられている、ことが好ましい。
また、本発明の剥離シートでは、前記一方の当接面の反対側に位置する他方の当接面には、線状の最深部である第2線状最深部が設けられた第2凹部が設けられ、前記第2凹部は、被着体に線接触可能な第2頂線を前記接着シートとは別の1の接着シートの接着剤層に形成可能に設けられている、ことが好ましい。
さらに、本発明の剥離シートでは、前記第1凹部の最深部には、前記接着シートが仮着されたときに、当該接着シートとの間に介在する空気を抜くまたは貯めることができる空気逃し部が設けられている、ことが好ましい。

It is preferable that the second recess is provided so that a second vertex capable of making point contact with the adherend is formed on an adhesive layer of one adhesive sheet different from the adhesive sheet.
In the release sheet of the present invention, the second concave portion provided with the second linear deepest portion, which is the linear deepest portion, is provided on the other contact surface located on the opposite side of the one contact surface. It is preferable that the second recess is provided so that a second top line that can be brought into line contact with the adherend is formed on an adhesive layer of one adhesive sheet different from the adhesive sheet.
Furthermore, in the release sheet of the present invention, when the adhesive sheet is temporarily attached to the deepest portion of the first recess, an air escape portion that can vent or store air interposed between the adhesive sheet and the first recess. Is preferably provided.
以上のような本発明によれば、接着剤を1の第1凹部全体に入り込むように積層することで、被着体に点接触可能な1の第1頂点または線接触可能な1の第1頂線を有し、当該第1頂点または第1頂線から離間したいずれの位置においても、当該第1頂点側または第1頂線側が外縁側に比べて肉厚に設けられた接着剤層を有する1の接着シートを第1凹部毎に形成することができ、簡単に被着体との間に気泡が形成されないように貼付することができる接着シートを製造することができる。このように製造された接着シートは、第1頂点または第1頂線を被着体に当接させ、そのまま接着シートを被着体に押圧するという1の動作によって、接着剤層と被着体との貼付領域を第1頂点または第1頂線から徐々に外縁側に広げ、空気を追い出すようにして貼付することができる。 According to the present invention as described above, by laminating the adhesive so as to enter the entire first concave portion, one first vertex that can make point contact with the adherend or one first that makes line contact.

It can be illustrated.
基材BS、接着剤AD層および剥離シートRLとしては、何ら制限はなく、基材BSは、例えば上質紙、グラシン紙、コート紙などの紙類、これらの紙類にポリエチレンなどの熱可塑性樹脂をラミネートしたラミネート紙、ポリエステル(例えばポリエチレンテレフタレート、ポリエチレンナフタレート)、ポリオレフィン(例えばポリプロピレン、ポリエチレン)、ポリ塩化ビニル、ポリ塩化ビニリデン、ポリスチレン、ポリカーボネート、ポリビニルアルコール、ポリウレタン、アクリル系樹脂などのプラスチック、セルローストリアセテート、セルロースジアセテート、セロハンなどのセルロース、天然ゴムやシリコンゴムなどのゴム、木材、金属、陶器、硝子、石材などで構成され、1μm〜100mmの厚みを有するものが例示できる。
接着剤AD層は、アクリル系、ゴム系、シリコーン系の粘着剤で構成され、1μm〜5mmの厚みを有するものが例示できる。
剥離シートRLは、帯状または枚葉状に形成されていてもよく、上記基材BSで例示したものや、上記基材BSで例示したものに、シリコーン系剥離剤、アルキルペンダント系剥離剤、縮合ワックス系剥離剤、フッ素系剥離剤、ポリエステル系剥離剤などの剥離剤を積層したものや、シリコーン樹脂、アルキルペンダント樹脂、縮合ワックス樹脂、フッ素樹脂、ポリエステル樹脂などそのものからなるものなどで構成され、1μm〜10mmの厚みを有するものが例示できる。
なお、これら基材BS、接着剤AD層および剥離シートRLの厚みは、技術常識に照らし合わせて前述した例示の厚み以上でもよいし、例示の厚み以下でもよい。また、第1点状最深部DPの深さDTは、1μm〜5mmのものが例示できるが、剥離シートRLの厚みを考慮してそれ以上の深さでもよいしそれ以下の深さでもよい。
また、接着剤AD層は、剥離シートRL上に積層するときや、被着体に押圧するときに流動性があることが好ましく、剥離シートRL上に積層するときに、接着面形成面FCに倣って第1凹部HLに入り込んだり、被着体に押圧するときに、当該接着剤AD層の凸形状が押し均されて厚みが略一様(略均等)になったりするとよい。なお、接着剤AD層は、加熱または冷却等の外力を加えることで流動性を発揮するものや流動性が向上するものでもよい。また、被着面側が変形可能なものである場合、接着剤AD層は、被着体に押圧するときに流動性が低くてもよいし流動性がなくてもよい。
The base material BS, the adhesive AD layer, and the release sheet RL are not particularly limited, and the base material BS is, for example, paper such as fine paper, glassine paper, and coated paper, and these papers are thermoplastic resins such as polyethylene. Laminated paper, polyester (eg, polyethylene terephthalate, polyethylene naphthalate), polyolefin (eg, polypropylene, polyethylene), polyvinyl chloride, polyvinylidene chloride, polystyrene, polycarbonate, polyvinyl alcohol, polyurethane, acrylic resin, cellulose Examples include cellulose such as triacetate, cellulose diacetate, and cellophane, rubber such as natural rubber and silicon rubber, wood, metal, ceramics, glass, stone, etc. and having a thickness of 1 μm to 100 mm. That.
The adhesive AD layer is composed of an acrylic, rubber-based, or silicone-based pressure-sensitive adhesive, and examples thereof have a thickness of 1 μm to 5 mm.
The release sheet RL may be formed in a strip shape or a sheet-like shape. Examples of the release material RL include those exemplified for the base material BS and those exemplified for the base material BS. Silicone release agents, alkyl pendant release agents, condensed waxes It is composed of a laminate of release agents such as a series release agent, a fluorine release agent, a polyester release agent, or a material composed of a silicone resin, an alkyl pendant resin, a condensed wax resin, a fluorine resin, a polyester resin, etc. The thing which has a thickness of 10 mm can be illustrated.
In addition, the thickness of these base material BS, adhesive agent AD layer, and peeling sheet RL may be more than the above-mentioned example thickness in light of technical common sense, and may be below the example thickness. Moreover, although the depth DT of the 1st point deepest part DP can illustrate a thing of 1 micrometer-5 mm, the depth beyond it may be sufficient in consideration of the thickness of the peeling sheet RL, and the depth below it may be sufficient.
The adhesive AD layer preferably has fluidity when laminated on the release sheet RL or when pressed against the adherend. When laminated on the release sheet RL, the adhesive AD layer is formed on the adhesive surface forming surface FC. It is preferable that the convex shape of the adhesive AD layer is squeezed and the thickness becomes substantially uniform (substantially equal) when entering the first concave portion HL along with the pressing and pressing the adherend. The adhesive AD layer may be one that exhibits fluidity or improves fluidity by applying an external force such as heating or cooling. Further, when the adherend side is deformable, the adhesive AD layer may have low fluidity or no fluidity when pressed against the adherend.
以上のような剥離シートRLを用いて接着シートASを製造する際には、まず人手または図示しない接着シート製造装置によって、剥離シートRLの一方の当接面RA上に、少なくとも第1凹部HL全体を塞ぐように流動性のある接着剤ADを塗布または積層する。次いで、ヒータやドライヤ等の乾燥機や紫外線照射装置等の硬化手段で接着剤AD層を硬化させる。この硬化は、完全硬化でも不完全硬化でもよいし、硬化手段で硬化させなくてもよい。次に、硬化された接着剤AD層上に基材BSを貼付または積層した後、当該基材BS上から第1凹部HLの外縁EGに沿ってカッター刃やレーザ等の切断手段で基材BSおよび接着剤AD層に切込を形成する。この切込を形成する位置は、第1凹部HLの外縁EGに完全一致する位置でもよいし、外縁EGの内側または外側の位置でもよく、外縁EGの外側に切込を形成する場合、接着シートASを被着体に貼付した後、当該外縁EGの外側を切断して排除することもできる。その後、ローラや吸引等の巻取手段で切込の外側に位置する接着剤AD層付きの基材BSを剥離シートRLから剥離する。これにより、接着面形成面FCによって形成された接着面FAと、側面形成面FDによって形成された側面FBとから構成された接着剤AD層が形成されて接着シートASが製造される。なお、一方の当接面RA上に接着剤ADを塗布または積層する際、空気逃し部EXとしての貫通孔HAから接着剤ADと第1凹部HLとの間に存在する空気を外部に抜くまたは、有底穴HBに貯めることで、接着シートASの接着面FAに空気溜まりが形成され、接着シートASに凹凸が形成されてしまうことを防止することができる。
接着シートASを被着体に貼付するときには、基材BS側から当該接着シートASを所定の平面からなる支持面を備えた支持手段で支持する。その後、被着体の被着面と接着シートASを支持した支持面とを略平行に配置し、支持面に略直交する方向に支持手段と被着体とを相対移動させて押圧する。これにより、初めに第1頂点TPが被着面に当接し、その後もそれらの相対移動により接着面FAが徐々に外縁に向かって貼付されてゆく。すなわち、第1頂点TPを被着体に当接させ、そのまま接着シートASを被着体に押圧するという1の動作によって、簡単に被着体との間に気泡が形成されないように当該接着シートASを被着体に貼付することができる。
When the adhesive sheet AS is manufactured using the release sheet RL as described above, first, at least the entire first concave portion HL is formed on one abutting surface RA of the release sheet RL by hand or an adhesive sheet manufacturing apparatus (not shown). A fluid adhesive AD is applied or laminated so as to block the film. Next, the adhesive AD layer is cured by a curing means such as a dryer such as a heater or a dryer or an ultraviolet irradiation device. This curing may be complete curing or incomplete curing, or may not be cured by a curing means. Next, after pasting or laminating the base material BS on the cured adhesive AD layer, the base material BS is cut from the base material BS along the outer edge EG of the first recess HL by a cutting means such as a cutter blade or a laser. And making cuts in the adhesive AD layer. The position where the cut is formed may be a position that completely coincides with the outer edge EG of the first recess HL, or may be a position inside or outside the outer edge EG. When the cut is formed outside the outer edge EG, the adhesive sheet After sticking AS to a to-be-adhered body, the outer side of the said outer edge EG can also be cut | disconnected and excluded. Thereafter, the base material BS with the adhesive AD layer located outside the cut is peeled from the release sheet RL by a winding means such as a roller or suction. As a result, an adhesive AD layer composed of the adhesive surface FA formed by the adhesive surface forming surface FC and the side surface FB formed by the side surface forming surface FD is formed, and the adhesive sheet AS is manufactured. When applying or laminating the adhesive AD on one abutment surface RA, the air existing between the adhesive AD and the first recess HL is extracted to the outside from the through hole HA as the air escape portion EX or By storing in the bottomed hole HB, it is possible to prevent an air reservoir from being formed on the adhesive surface FA of the adhesive sheet AS and forming irregularities on the adhesive sheet AS.
When adhering the adhesive sheet AS to the adherend, the adhesive sheet AS is supported from the base material BS side by a support means having a support surface composed of a predetermined plane. Thereafter, the adherend surface of the adherend and the support surface supporting the adhesive sheet AS are arranged substantially in parallel, and the support means and the adherend are relatively moved and pressed in a direction substantially orthogonal to the support surface. Thereby, the first vertex TP first comes into contact with the adherend surface, and thereafter, the adhesive surface FA is gradually stuck toward the outer edge by the relative movement thereof. That is, the first apex TP is brought into contact with the adherend and the adhesive sheet AS is pressed against the adherend as it is so that air bubbles are not easily formed between the adherend and the adherend. AS can be affixed to an adherend.
以上のような第1実施形態によれば、簡単に被着体との間に気泡が形成されないように貼付することができる接着シートASを製造することができる。 According to the first embodiment as described above, it is possible to manufacture the adhesive sheet AS that can be easily attached so that bubbles are not formed between the adherend and the adherend.
