Description

本発明は、難燃性が要求される部材などを固定するために使用される難燃性フィルム粘着テープ又はシートに関する。   The present invention relates to a flame retardant film pressure-sensitive adhesive tape or sheet used for fixing a member or the like that requires flame retardancy.

従来より、電子部品関係や電子機器関連、航空機、原子力発電所など、様々な分野で難燃性が要求されている。これに対応すべく、それら分野で使用される部材には難燃性が付与され、同時にこれら部材を固定する粘着テープ又はシートにも難燃性が付与されている。粘着テープ又はシートに難燃性を付与する手段として、基材及び／或いは粘着剤中にハロゲン化物、リン化合物、水酸化アルミニウム、水酸化マグネシウム、メラミンなどの難燃剤を配合することが知られている。   Conventionally, flame retardancy is required in various fields such as electronic parts, electronic equipment, aircraft, and nuclear power plants. In order to cope with this, flame retardance is imparted to members used in these fields, and at the same time, flame retardancy is imparted to an adhesive tape or sheet for fixing these members. As a means of imparting flame retardancy to adhesive tapes or sheets, it is known to incorporate flame retardants such as halides, phosphorus compounds, aluminum hydroxide, magnesium hydroxide, melamine in the base material and / or adhesive. Yes.

例えば、特許文献１〜４には、様々な難燃剤を用いた難燃性基材に難燃性を有さない粘着剤を塗布した粘着テープが提案されている。   For example, Patent Documents 1 to 4 propose pressure-sensitive adhesive tapes in which a pressure-sensitive adhesive having no flame retardancy is applied to a flame-retardant base material using various flame retardants.

これに対し、例えば、特許文献５には、ポリリン酸アンモニウムなどの液状難燃剤を含有する難燃性粘着剤が提案されている。また、特許文献６には、マイクロカプセル化した難燃剤と無機酸化物を含有する粘着剤が提案されている。

Patent Document 6 proposes a pressure-sensitive adhesive containing a microencapsulated flame retardant and an inorganic oxide.
JP-A-5-47249 JP-A-5-202340 JP 2001-49208 A JP 2002-138263 A Japanese Patent Laid-Open No. 10-110082 JP-A-6-25629

しかし、特許文献１〜４に記載の粘着テープは、粘着剤が難燃性を有していないため、粘着剤を塗布することにより難燃性が大きく低下することが容易に推測できる。   However, since the pressure-sensitive adhesives described in Patent Documents 1 to 4 do not have flame retardancy, it can be easily estimated that the flame retardancy is greatly reduced by applying the pressure-sensitive adhesive.

また、特許文献５に記載の粘着剤は、粘着剤の凝集力を低下させたり、あるいは、粘着剤表面にブリードしたりなど、テープ特性を低下させてしまう。また、特許文献６に記載のマイクロカプセルや無機酸化物などの固形の難燃剤による難燃化は、難燃剤の添加に伴い粘着剤が硬くなり、液状難燃剤同様、粘着特性を損なってしまう。   In addition, the pressure-sensitive adhesive described in Patent Document 5 deteriorates tape properties such as reducing the cohesive force of the pressure-sensitive adhesive or bleeding on the surface of the pressure-sensitive adhesive. Moreover, the flame retarding by solid flame retardants, such as the microcapsule and inorganic oxide described in Patent Document 6, hardens the pressure-sensitive adhesive with the addition of the flame retardant and impairs the pressure-sensitive adhesive properties like the liquid flame retardant.

本発明の目的は、難燃性フィルム基材面に難燃性を付与していない、或いは、難燃化していても高い難燃性を付与していない粘着剤を塗布しても、上記フィルム基材の難燃性を損なわず、且つ、粘着特性を著しく低下させない粘着テープ又はシートを提供することにある。   The object of the present invention is to provide the above film even if an adhesive that does not impart flame retardancy to the flame retardant film substrate surface or is not flame retardant even if flame retardant is applied. An object of the present invention is to provide an adhesive tape or sheet that does not impair the flame retardancy of a substrate and does not significantly reduce the adhesive properties.

本発明の目的を達成するために、本発明は特許請求の範囲に記載のような構成とするものである。   In order to achieve the object of the present invention, the present invention is configured as described in the claims.

すなわち、本発明は、難燃性を有するフィルム基材面に、難燃性を付与していない、或いは、付与していても上記フィルム基材より低い難燃性を有する粘着剤を塗布した難燃性フィルム粘着テープ又はシートにおいて、上記粘着剤の塗布面積を、上記フィルム基材面の面積未満とする。   That is, in the present invention, it is difficult to apply a pressure-sensitive adhesive having a flame retardancy lower than that of the film base material to the film base surface having flame retardancy. In the flammable film pressure-sensitive adhesive tape or sheet, the application area of the pressure-sensitive adhesive is less than the area of the film substrate surface.

この場合、上記粘着剤の塗布面積を、上記フィルム基材面の１０〜９０％とする。   In this case, the application area of the pressure-sensitive adhesive is 10 to 90% of the film base surface.

また、これらの場合、上記粘着剤の塗布面積を、上記フィルム基材面の３０〜７０％とする。   Moreover, in these cases, the application area of the pressure-sensitive adhesive is 30 to 70% of the film substrate surface.

また、これらの場合、上記フィルム基材面に上記粘着剤の層をスジ塗りにより設ける。   In these cases, the pressure-sensitive adhesive layer is provided on the film substrate surface by streaking.

本発明は、難燃性を有するフィルム基材面に、難燃性を付与していない、或いは、付与していても上記フィルム基材より低い難燃性を有する粘着剤を塗布した難燃性フィルム粘着テープ又はシートにおいて、上記粘着剤の塗布面積が、上記フィルム基材面の面積未満であるから、上記フィルム基材の難燃性を低下させることがない。   In the present invention, flame retardancy is not imparted to the film substrate surface having flame retardancy, or is applied with an adhesive having flame retardancy lower than that of the film substrate even if imparted. In the film pressure-sensitive adhesive tape or sheet, the application area of the pressure-sensitive adhesive is less than the area of the film base material surface, so that the flame retardancy of the film base material is not lowered.

この場合、上記粘着剤の塗布面積が、上記フィルム基材面の１０〜９０％であるから、上記フィルム基材の難燃性を損なわず、且つ、粘着特性を著しく低下させない。   In this case, since the application area of the pressure-sensitive adhesive is 10 to 90% of the surface of the film base material, the flame retardancy of the film base material is not impaired, and the adhesive properties are not significantly reduced.

また、これらの場合、上記粘着剤の塗布面積が、上記フィルム基材面の３０〜７０％であるから、上記フィルム基材の難燃性を損なわず、且つ、粘着特性を著しく低下させない。   Moreover, in these cases, since the application area of the pressure-sensitive adhesive is 30 to 70% of the film base material surface, the flame retardancy of the film base material is not impaired, and the adhesive property is not significantly lowered.

また、これらの場合、上記フィルム基材面に上記粘着剤の層をスジ塗りにより設けてあるから、上記フィルム基材の難燃性を損なわず、且つ、粘着特性を著しく低下させない。   In these cases, the pressure-sensitive adhesive layer is provided on the surface of the film base material by streaking, so that the flame retardancy of the film base material is not impaired and the adhesive properties are not significantly lowered.

本発明者は、材料・プロセスを種々検討した結果、下記の方法により上記課題を解決できることを確認した。   As a result of various studies on materials and processes, the present inventor has confirmed that the above problem can be solved by the following method.

すなわち、本発明の難燃性フィルム粘着テープ又はシートは、難燃性を有するフィルム基材面に、難燃性を付与していない、或いは、付与していても上記フィルム基材より低い難燃性を有する粘着剤を塗布した粘着テープ又はシートにおいて、上記粘着剤の塗布面積を、上記フィルム基材面の面積未満とすることにより得られることを見い出した。   That is, the flame-retardant film pressure-sensitive adhesive tape or sheet of the present invention does not impart flame retardancy to the film substrate surface having flame retardancy, or is flame retarded lower than the film substrate even if imparted. In the pressure-sensitive adhesive tape or sheet to which a pressure-sensitive adhesive is applied, it has been found that the area of application of the pressure-sensitive adhesive is less than the area of the film substrate surface.

また、本発明の難燃性フィルム粘着テープ又はシートは、上記粘着剤の塗布量を減少させることでは得られるものではなく、スジ塗り、或いは、ドット印刷などにより、上記粘着剤の塗布面積を上記フィルム基材面の面積未満とすることにより得られることが分かった。   In addition, the flame-retardant film adhesive tape or sheet of the present invention is not obtained by reducing the amount of the adhesive applied, but the application area of the adhesive is increased by streaking or dot printing. It turned out that it is obtained by setting it as less than the area of a film base material surface.

上記したスジ塗りやドット印刷は、通常、通気性を有する粘着テープを作成する目的等で適用されている。（例えば、特開平１０−３２８２３１号公報）
すなわち、通気性を有する粘着テープは、通気性のある基材にスジ塗りやドット印刷により粘着剤層を設けることにより、通気性のある基材と被着体との間に隙間をつくり、粘着テープに通気性を持たせている。しかし、粘着テープに難燃性を保持するために、スジ塗りやドット印刷を適用している例は無い。 The above-described streak coating and dot printing are usually applied for the purpose of creating a pressure-sensitive adhesive tape. (For example, JP-A-10-328231)
In other words, an air-permeable adhesive tape creates a gap between the air-permeable substrate and the adherend by providing an adhesive layer on the air-permeable substrate by streaking or dot printing. The tape is breathable. However, there are no examples in which streaks or dot printing is applied in order to maintain the flame retardancy of the adhesive tape.

以下、本発明の難燃性フィルム粘着テープ又はシートについて、図を用いて具体的に説明する。   Hereinafter, the flame-retardant film adhesive tape or sheet of the present invention will be specifically described with reference to the drawings.

本発明の難燃性フィルム粘着テープ５は、図１、図２に示すように、難燃性フィルム基材層１と、粘着剤層２とから構成される。尚、図３、４に示すように、難燃性フィルム基材層１の粘着剤未塗布面に離型剤層３を設ける。また、粘着剤層２の表面に離型紙４を貼り合わせてもよい。   The flame retardant film adhesive tape 5 of the present invention is composed of a flame retardant film base material layer 1 and an adhesive layer 2 as shown in FIGS. 3 and 4, the release agent layer 3 is provided on the non-adhesive surface of the flame retardant film base material layer 1. Moreover, the release paper 4 may be bonded to the surface of the pressure-sensitive adhesive layer 2.

難燃性フィルム基材のベース樹脂は、フィルム状形態が得られるものであれば、特に、限定するのもではなく、ポリエチレン、ポリプロピレン、エチレン−酢酸ビニル、ポリエステルなどを使用することができる。   The base resin of the flame retardant film base is not particularly limited as long as a film-like form can be obtained, and polyethylene, polypropylene, ethylene-vinyl acetate, polyester, and the like can be used.

難燃性フィルム基材に配合する難燃剤は、特に、限定するものではなく、臭素系難燃剤、リン系難燃剤、アンチモン系難燃剤、窒素系難燃剤などを使用することができる。   The flame retardant blended in the flame retardant film substrate is not particularly limited, and bromine flame retardant, phosphorus flame retardant, antimony flame retardant, nitrogen flame retardant and the like can be used.

また、難燃性フィルム基材には、必要に応じて、手切れ性などの特性を付与することができる。   Moreover, characteristics, such as hand cutting property, can be provided to a flame-retardant film base material as needed.

粘着剤は、用途や被着体に応じて、ゴム系、アクリル系、シリコーン系など汎用のものを使用することができ、厚さは、特に、制限されるものではないが、粘着剤の塗布面積は、フィルム基材の面積未満とする。好ましくは、フィルム基材面積の１０〜９０％、より好ましくは、フィルム基材面積の３０〜７０％の範囲である。   The pressure-sensitive adhesive can be a general-purpose material such as rubber, acrylic and silicone depending on the application and adherend, and the thickness is not particularly limited, but the pressure-sensitive adhesive is applied. The area is less than the area of the film substrate. Preferably, it is 10 to 90% of the film substrate area, and more preferably 30 to 70% of the film substrate area.

粘着剤の塗布面積がフィルム基材面積の９０％を超えると、粘着力は高い値を示すが、難燃性が著しく低下する。また、粘着剤の塗布面積がフィルム基材面積の１０％未満の場合、難燃性は高い値を示すが、粘着力が著しく低下する。また、粘着剤の塗布面積がフィルム基材面積の７０％を超えると、粘着力は良好であるが、難燃性が若干低下する。また、粘着剤の塗布面積がフィルム基材面積の３０％未満の場合、難燃性こそ発揮するが、粘着力が若干低下する。   When the application area of the pressure-sensitive adhesive exceeds 90% of the film base material area, the adhesive strength shows a high value, but the flame retardancy is remarkably lowered. Moreover, when the application area of an adhesive is less than 10% of a film base material area, although a flame retardance shows a high value, adhesive force falls remarkably. Moreover, when the application area of an adhesive exceeds 70% of a film base material area, although adhesive force is favorable, a flame retardance falls a little. Moreover, when the application area of an adhesive is less than 30% of a film base material area, although flame retardancy will be exhibited, adhesive force will fall a little.

また粘着剤には、必要に応じて、粘着付与剤、安定剤、充填剤など、公知の添加剤を配合してもよい。   Moreover, you may mix | blend well-known additives, such as a tackifier, a stabilizer, and a filler, with an adhesive as needed.

以下、本発明の難燃性フィルム粘着テープ又はシートについて、実施例によって具体的に説明する。   Hereinafter, the flame-retardant film pressure-sensitive adhesive tape or sheet of the present invention will be specifically described with reference to examples.

〔実施例１〜８〕

A flame-retardant film (trade name Tadan oxygen index 30 manufactured by Aicello Co., Ltd.) and an acrylic pressure-sensitive adhesive (Coponil N-4135 oxygen index 18 manufactured by Nippon Gosei Kagaku Co., Ltd.) were streaked and coated under the conditions shown in Table 1. A flame retardant film adhesive tape was obtained.

〔比較例１〕
塗布面積を１００％とした以外は、実施例１と同様にフィルム粘着テープを作成した。 [Comparative Example 1]
A film adhesive tape was prepared in the same manner as in Example 1 except that the coating area was 100%.

粘着力の測定方法：ＪＩＳ Ｚ ０２３７に準じ測定した。２３℃×５０％ＲＨ雰囲気中で、ステンレス板にテープを貼り付け、２ｋｇローラーで１往復させて圧着し、２０分放置した後、テープを１８０°方向に引き剥がしたときの剥離力を測定する。
Figure 2008050423
 Method for measuring adhesive strength: Measured according to JIS Z 0237. Affix the tape to a stainless steel plate in a 23 ° C x 50% RH atmosphere, reciprocate once with a 2kg roller, leave it for 20 minutes, and then measure the peel force when the tape is peeled in the 180 ° direction. .

酸素指数の測定方法：ＪＩＳ Ｋ ７２０１−２に準じ、Ｖ型試験片、伝ぱ点火による測定手順により、試料が有炎燃焼を維持するのに必要な２３±２℃の酸素と窒素の混合ガスの最小濃度（容積％）を測定した。   Measurement method of oxygen index: According to JIS K 7201-2, the measurement procedure by V-type test piece and propagation ignition is used to measure the mixed gas of oxygen and nitrogen at 23 ± 2 ℃ necessary for the sample to maintain flammable combustion. The minimum concentration (% by volume) was measured.

以上の測定結果を表２に示す。表からわかるように、実施例１〜８のフィルム粘着テープは、基材フィルムの酸素指数を低下させることなく、また、著しい粘着力の低下も見られない。これに対し粘着剤を全面に塗工した比較例１は、粘着力こそ高いものの、酸素指数は著しく低下してしまう。また、塗布面積を１００％にして、粘着剤厚さを薄くして、粘着剤塗布量を実施例１と同一にした比較例２は、粘着力は高い値を示したものの、難燃性が著しく低下した。更に、粘着剤の塗布面積を５％まで減らした比較例３は、著しい粘着力の低下が見られ、実使用不可能であった。また、粘着剤の塗布面積を９５％まで増やした比較例４は、著しく難燃性が低下した。   The above measurement results are shown in Table 2. As can be seen from the table, the film adhesive tapes of Examples 1 to 8 do not decrease the oxygen index of the base film, and no significant decrease in adhesive strength is observed. On the other hand, in Comparative Example 1 in which the pressure-sensitive adhesive was applied to the entire surface, although the adhesive strength was high, the oxygen index was significantly lowered. In Comparative Example 2 where the application area was 100%, the adhesive thickness was reduced, and the adhesive application amount was the same as in Example 1, the adhesive strength showed a high value, but the flame retardancy was low. Remarkably reduced. Furthermore, in Comparative Example 3 in which the application area of the adhesive was reduced to 5%, a significant decrease in the adhesive strength was observed, and the actual use was impossible. Moreover, the flame retardance fell remarkably in the comparative example 4 which increased the application area of the adhesive to 95%.
