Description
本発明は、剥離処理剤、剥離剤、剥離処理層、剥離処理層の製造方法、剥離シート、粘着テープおよび粘着シートに関する。 The present invention relates to a release treatment agent, a release agent, a release treatment layer, a method for producing a release treatment layer, a release sheet, an adhesive tape, and an adhesive sheet.
感圧粘着テープや粘着シート等の粘着剤を用いた製品では、通常、剥離処理剤による剥離処理が実施されている。例えば、前記粘着テープでは、粘着面を保護するために、テープを巻回状態としているが、テープ背面（前記粘着面に対し裏面）に剥離処理剤による剥離処理層を形成することにより、使用性を向上させている。また、前記粘着シートでは、粘着剤層が形成された面に、その表面に剥離処理層が形成された剥離シートが配置されている。粘着テープ等に使用される剥離処理剤は、シリコーン系剥離処理剤と非シリコーン系剥離処理剤に大別することができる。 In products using pressure-sensitive adhesive tapes or pressure-sensitive adhesives such as pressure-sensitive adhesive sheets, release treatment with a release treatment agent is usually performed. For example, in the pressure-sensitive adhesive tape, the tape is wound in order to protect the pressure-sensitive adhesive surface, but by forming a release treatment layer with a release treatment agent on the back surface of the tape (the back surface relative to the pressure-sensitive adhesive surface) Has improved. Moreover, in the said adhesive sheet, the peeling sheet by which the peeling process layer was formed in the surface is arrange | positioned at the surface in which the adhesive layer was formed. Release treatment agents used for adhesive tapes and the like can be broadly classified into silicone release treatment agents and non-silicone release treatment agents.
前記シリコーン系剥離処理剤としては、剥離紙用オルガノポリシロキサン組成物等が提案されている（特許文献１参照）。この剥離処理剤は、他の剥離処理剤と比較して、剥離性が良くて剥離時の耳障りな音（ノッキング）が起こらないという特性を有し、また、耐熱性、耐溶剤性、耐水性にも優れている。しかしながら、この剥離処理剤は、印字性が悪く印刷加工ができないという問題がある。また、この剥離処理剤は、マイグレートの問題もある。マイグレートとは、粘着テープのように、基材の表面に粘着剤層が形成され、裏面に剥離処理層が形成されている場合、剥離処理剤の成分が前記基材に浸透して反対側の粘着剤層にまで到達し、これにより粘着性が低下するという問題である。そして、この剥離処理剤による処理温度は、他の剥離処理剤と比較して高温（１００℃以上）であり、そのため、配向ポリプロピレン（ＯＰＰ）やポリエチレン（ＰＥ）等のような耐熱性の低い基材には適用できないという問題がある。 As the silicone release agent, an organopolysiloxane composition for release paper has been proposed (see Patent Document 1). Compared to other release treatment agents, this release treatment agent has characteristics that it has good releasability and does not cause annoying noise (knocking) at the time of peeling, and has heat resistance, solvent resistance, water resistance. Also excellent. However, this release treatment agent has a problem that printability is poor and printing cannot be performed. Further, this release treatment agent also has a problem of migration. When the adhesive layer is formed on the surface of the base material and the release treatment layer is formed on the back surface, like the adhesive tape, the migration means that the component of the release treatment agent penetrates into the base material and is on the opposite side. The pressure-sensitive adhesive layer is reached, and thus the adhesiveness is lowered. And the processing temperature by this peeling treatment agent is high temperature (100 degreeC or more) compared with other peeling treatment agents, Therefore, group with low heat resistance like oriented polypropylene (OPP), polyethylene (PE), etc. There is a problem that it cannot be applied to materials.
一方、前記非シリコーン系剥離処理剤としては、エチレン／ビニルアルコール共重合体とアルキルイソシアネートの反応生成物等が提案されている（特許文献２参照）。しかしながら、前記反応生成物を主体とする剥離処理剤は、印字性には優れるが、剥離性が悪く、剥離時にノッキングを起こすという問題がある。 On the other hand, as the non-silicone release treatment agent, a reaction product of an ethylene / vinyl alcohol copolymer and an alkyl isocyanate has been proposed (see Patent Document 2). However, the release treatment agent mainly composed of the reaction product is excellent in printability, but has a problem that the release property is poor and knocking occurs at the time of peeling.
この他に、前記非シリコーン系剥離処理剤として、エチレンオキサイド基およびプロピレンオキサイド基の少なくとも一方を２０質量％含有し、溶解度パラメータが８．５〜１１．０（ｃａｌ／ｃｍ3）1/2の範囲にある重合体が提案されている（特許文献３参照）。しかしながら、前記重合体は、粘度が高いため、基材への均一な塗工が難しく、場合によっては必要以上に基材に塗工してしまい、経済的に不利となる場合がある。また、この剥離処理剤は、スチレン−イソプレン−スチレン（ＳＩＳ）系粘着テープ（基材）に対する剥離性が不十分であるという問題もある。
本発明は、このような事情に鑑みなされたものであり、使用時に容易に剥離でき、ノッキングも起こらず、かつ、印字性、耐老化性、耐熱性に優れる剥離処理剤の提供を、その目的とする。 The present invention has been made in view of such circumstances, and its purpose is to provide a release treatment agent that can be easily peeled off during use, does not cause knocking, and is excellent in printability, aging resistance, and heat resistance.

つぎに、本発明の剥離処理剤について、例を挙げて説明する。 Next, the release treatment agent of the present invention will be described with examples.
前述のとおり、本発明の剥離処理剤は、多価アルコールと、無水マレイン酸骨格を有する高分子とを含有する。 As described above, the release treatment agent of the present invention contains a polyhydric alcohol and a polymer having a maleic anhydride skeleton.
前記多価アルコールとしては、特に制限されず、公知の種々の多価アルコールを用いることができる。具体的には、例えば、ポリエチレングリコール（ＰＥＧ）、ポリプロピレングリコールのエチレンオキシド付加物、１，３−ブチレングリコール、エチレングリコール、プロピレングリコール、グリセリン、ジグリセリン、トリグリセリン、ポリグリセリン、ジエチレングリコール、ジプロピレングリコール、トリエチレングリコール、ポリエチレン、ポリプロピレングリコール等を用いることができる。これらの中でも、粘着テープ等に濡れにくい性質を有する点等から、ＰＥＧを用いることが好ましい。前記多価アルコールの質量平均分子量は、４００〜２００００の範囲であることが好ましい。この範囲とすることで、分子量が小さすぎて前記多価アルコールと前記無水マレイン酸骨格を有する高分子との架橋が不十分となり、剥離処理層の強度や粘着テープ等の再接着性が不十分となることや、分子量が大きすぎて前記無水マレイン酸骨格を有する高分子との相溶性が低くなり、剥離処理層が不均一になることや一部が白色化すること等を防止できる。なお、前記多価アルコールの質量平均分子量は、より好ましくは、４００〜４０００の範囲であり、さらに好ましくは、１０００〜２０００の範囲である。 The polyhydric alcohol is not particularly limited, and various known polyhydric alcohols can be used.

Among these, it is preferable to use PEG because it has a property that it is difficult to wet the adhesive tape or the like. The polyhydric alcohol preferably has a mass average molecular weight in the range of 400 to 20000. By setting it within this range, the molecular weight is too small, and crosslinking between the polyhydric alcohol and the polymer having the maleic anhydride skeleton becomes insufficient, and the strength of the release treatment layer and the re-adhesiveness such as an adhesive tape are insufficient. And the compatibility with the polymer having the maleic anhydride skeleton due to the excessively high molecular weight is reduced, and the release treatment layer can be prevented from becoming non-uniform or partially whitened. In addition, the mass average molecular weight of the polyhydric alcohol is more preferably in the range of 400 to 4000, and still more preferably in the range of 1000 to 2000.

Among these, methyl vinyl ether maleic anhydride copolymer is preferable from the viewpoint of peelability and the like. The molecular weight of the polymer having a maleic anhydride skeleton is, for example, in the range of 200,000 to 3,000,000, preferably in the range of 500,000 to 2.5 million, and more preferably in the range of 1,000,000 to 2,000,000. is there.
前記多価アルコールと前記無水マレイン酸骨格を有する高分子との比率は、前述のとおりである。また、前述のとおり、本発明の剥離処理剤は、さらに、酸性触媒を含有してもよい。 The ratio of the polyhydric alcohol and the polymer having a maleic anhydride skeleton is as described above. Moreover, as described above, the release treating agent of the present invention may further contain an acidic catalyst.
つぎに、本発明の剥離剤について、例を挙げて説明する。 Next, the release agent of the present invention will be described with examples.
前述のとおり、本発明の剥離剤は、本発明の剥離処理剤中の多価アルコールと無水マレイン酸骨格を有する高分子とのエステル化反応で得られる架橋ポリマーを含む。この架橋ポリマーは、具体的には、つぎのようにして生成する。 As described above, the release agent of the present invention includes a crosslinked polymer obtained by an esterification reaction between the polyhydric alcohol in the release treatment agent of the present invention and a polymer having a maleic anhydride skeleton.

Wake up. The general formula of the first stage esterification reaction is shown in the following formula (1).
ついで、さらに、前記高分子の無水マレイン酸骨格が開環して、上記式（１）の反応生成物と２段目のエステル化反応を起こし、架橋ポリマーとなる。前記２段目のエステル化反応の一般式を、下記式（２）に示す。 Then, the maleic anhydride skeleton of the polymer is further opened to cause a second-stage esterification reaction with the reaction product of the above formula (1) to become a crosslinked polymer. A general formula of the esterification reaction in the second stage is shown in the following formula (2).
上記式（１）、（２）において、Ｒ1、Ｒ2は、任意の基であり、ｌ、ｎは、任意の自然数である。例えば、前記無水マレイン酸骨格を有する高分子がメチルビニルエーテル無水マレイン酸共重合体であり、前記多価アルコールがＰＥＧである場合には、上記式（１）、（２）において、Ｒ1は、メチルビニルエーテル基であり、Ｒ2は、エチレン基である。また、ｌは、例えば、１０００〜２００００の範囲であり、ｎは、例えば、５〜５００の範囲である。なお、このようにして得られた架橋ポリマーは、ゲル状であり、薄膜化が可能である。 In the above formulas (1) and (2), R 1 and R 2 are arbitrary groups, and l and n are arbitrary natural numbers. For example, when the polymer having a maleic anhydride skeleton is a methyl vinyl ether maleic anhydride copolymer and the polyhydric alcohol is PEG, in the above formulas (1) and (2), R 1 is It is a methyl vinyl ether group, and R 2 is an ethylene group. Moreover, l is the range of 1000-20000, for example, and n is the range of 5-500, for example. In addition, the crosslinked polymer obtained in this way is gel-like and can be thinned.

When the base material is the resin film, it may be stretched or non-stretched, but from the viewpoint of strength, it is more preferably stretched, for example, a stretched polypropylene film, a stretched polyester film, etc. preferable. The draw ratio is not particularly limited. In addition, when the said base material is the said resin film, surface treatment may be given by conventional surface treatment methods, such as a corona discharge treatment and a plasma treatment.

This is the release treatment layer. The temperature of the heat treatment and the film thickness of the release treatment layer are as described above. As described above, the surface on which the release treatment layer is formed may be a part or all of a predetermined surface of the substrate.

A pressure-sensitive adhesive layer is formed on one surface of the pressure-sensitive adhesive tape and pressure-sensitive adhesive sheet (the surface opposite to the surface on which the release treatment layer is formed), but the type and manufacturing method are not particularly limited. Examples of the pressure-sensitive adhesive forming the pressure-sensitive adhesive layer include a rubber-based pressure-sensitive adhesive and an acrylic pressure-sensitive adhesive.

前記実施例１〜６および比較例１〜４で作製した剥離処理層の剥離性（常温常圧試験）および印字性を、前述の方法により評価した。その評価結果を、下記表１に示す。また、実施例７〜１０については、剥離性（常温常圧試験）および剥離性（耐老化および耐熱性試験）を、前述の方法により評価した。その評価結果を、下記表２に示す。 The peelability (room temperature and normal pressure test) and printability of the release treatment layers prepared in Examples 1 to 6 and Comparative Examples 1 to 4 were evaluated by the methods described above. The evaluation results are shown in Table 1 below. Moreover, about Examples 7-10, peelability (normal temperature normal pressure test) and peelability (aging resistance and heat resistance test) were evaluated by the above-mentioned method. The evaluation results are shown in Table 2 below.
上記表１より、実施例１〜６で作製した剥離処理層は、剥離性（常温常圧試験）および印字性の双方の特性に優れていることが分かる。これに対し、比較例１〜４では、剥離性（常温常圧試験）および印字性の双方若しくはいずれかの特性に問題があった。また、上記表２から分かるように、本発明の剥離処理剤によれば、耐老化性および耐熱性にも優れた剥離処理層を作製できた。 From Table 1 above, it can be seen that the release treatment layers prepared in Examples 1 to 6 are excellent in both properties of peelability (normal temperature and normal pressure test) and printability. On the other hand, in Comparative Examples 1-4, there existed a problem in the releasability (normal temperature normal pressure test) and / or printability. Further, as can be seen from Table 2 above, according to the release treatment agent of the present invention, a release treatment layer excellent in aging resistance and heat resistance could be produced.
本発明の剥離処理剤は、剥離性に優れるためノッキングも起こらず、かつ、耐熱性、耐老化性、印字性に優れる。したがって、本発明の剥離処理剤は、例えば、剥離シート、粘着シート、粘着テープ等に好ましく使用できるが、その用途は制限されず、広い。 Since the release treatment agent of the present invention is excellent in releasability, it does not cause knocking and is excellent in heat resistance, aging resistance, and printability. Therefore, the release treatment agent of the present invention can be preferably used for, for example, a release sheet, a pressure-sensitive adhesive sheet, a pressure-sensitive adhesive tape, etc., but its application is not limited and is wide.
