Description

本発明は、導電性、接着性、耐薬品性に優れ、透明性をもち、かつ加熱後も前記特性を保持する電気部品用保護シートである。 The present invention is a protective sheet for electrical parts that is excellent in conductivity, adhesion, and chemical resistance, has transparency, and retains the above characteristics even after heating.

電子機器の製造工程中では、電子部品にさまざまな保護シートが貼り付けられ、製造時の傷、薬品から電子部品の表面を保護するために用いられている。 During the manufacturing process of an electronic device, various protective sheets are attached to the electronic component and used to protect the surface of the electronic component from scratches and chemicals during manufacturing.

保護シートは、一般に、シート状の基材層と粘着剤で形成される粘着層で形成されている。基材としては、ポリプロピレン、ポリエチレン等の汎用の熱可塑性樹脂が用いられている(特許文献1及び2参照)。しかしながら、これら汎用の熱可塑性樹脂では、120℃程度しか耐熱性がないため、高温で使用することができないという制限があった。一方、高温でも使用可能なポリイミド系熱硬化性樹脂を用いた保護シートでは、非常に高価なため、限られた用途にしか使用することができない問題があった。

The protective sheet is generally formed of a pressure-sensitive adhesive layer formed of a sheet-like base material layer and a pressure-sensitive adhesive. As the base material, general-purpose thermoplastic resins such as polypropylene and polyethylene are used (see Patent Documents 1 and 2). However, these general-purpose thermoplastic resins have a heat resistance of only about 120 ° C., and thus have a limitation that they cannot be used at high temperatures. On the other hand, a protective sheet using a polyimide-based thermosetting resin that can be used even at high temperatures is very expensive and has a problem that it can be used only for limited applications.
JP 2004-287199 A JP2007-012354

保護シートに高い導電性を付与したい場合、一般に導電性フィラーと呼ばれる無機物質を数十質量部程度添加する必要があるが、この場合、保護シートの透明性は著しく低くなる。 When it is desired to impart high conductivity to the protective sheet, it is necessary to add about tens of parts by mass of an inorganic substance generally called a conductive filler. In this case, the transparency of the protective sheet is remarkably lowered.

保護シートを電子部品に用い、製造工程中でさまざまな薬品による処理を行う際、N−メチル−2−ピロリドンなどの強力な薬品を使用するとフィルムの劣化や、剥離などがおこり、次工程に移る際、保護シートを張り替える必要がある。 When using protective sheets for electronic parts and processing with various chemicals during the manufacturing process, if strong chemicals such as N-methyl-2-pyrrolidone are used, the film will deteriorate or peel off and move on to the next process. At that time, it is necessary to replace the protective sheet.

本発明は上記の事情に鑑みてなされたものであり、電気部品を保護し、導電性、耐薬品性に優れ、かつ150℃での使用環境化でも前記物性を維持し、かつ透明性を付与した保護シートを提供することを目的としてなされたものである。 The present invention has been made in view of the above circumstances, protects electrical components, is excellent in electrical conductivity and chemical resistance, maintains the above physical properties even in a use environment at 150 ° C., and imparts transparency. It was made for the purpose of providing a protective sheet.

請求項1に記載の発明は、基材層と粘着層からなる保護シートであって、基材層を構成する基材樹脂は、炭素繊維が含有され、炭素繊維の炭素繊維長が100μm以下、かつ、「炭素繊維長/炭素繊維の直径」の値が100以上であり、エポキシ樹脂と硬化剤の複合体であり、エポキシ樹脂はトリアジン骨格を有し、硬化剤はエーテル結合もしくはエステル結合を分子内に含んだものであり、粘着層を構成する粘着樹脂は、シリコーンとビスフェノールA型エポキシ樹脂の共重合体と、エーテル結合もしくはエステル結合を分子内に含む硬化剤の複合体であり、シリコーンは粘着樹脂の35〜65質量%であり、ビスフェノールA型エポキシ樹脂は粘着樹脂の末端部に配置されたことを特徴とする保護シートである。 Invention of Claim 1 is a protective sheet which consists of a base material layer and an adhesion layer, Comprising: Base material resin which comprises a base material layer contains carbon fiber, The carbon fiber length of carbon fiber is 100 micrometers or less, In addition, the value of “carbon fiber length / carbon fiber diameter” is 100 or more, and is a composite of an epoxy resin and a curing agent, the epoxy resin has a triazine skeleton, and the curing agent has an ether bond or an ester bond as a molecule. The adhesive resin included in the adhesive layer is a composite of a copolymer of silicone and a bisphenol A type epoxy resin and a curing agent containing an ether bond or an ester bond in the molecule. The protective sheet is 35 to 65% by mass of the adhesive resin, and the bisphenol A type epoxy resin is disposed at the end of the adhesive resin.

本発明の保護シートは耐熱性に優れ、加熱後も導電性、接着性、耐薬品性の低下が少ないため、使用の制限がなくなり、作業性がよく、かつしっかりと電子部品を保護できる。 The protective sheet of the present invention is excellent in heat resistance and has little decrease in conductivity, adhesiveness and chemical resistance even after heating. Therefore, there are no restrictions on use, workability is good, and electronic parts can be firmly protected.

以下、本発明を実施するための最良の形態について詳細に説明する。 Hereinafter, the best mode for carrying out the present invention will be described in detail.

基材層を構成する基材樹脂は、エポキシ樹脂と硬化剤の複合体であり、エポキシ樹脂はトリアジン骨格を有し、硬化剤はエーテル結合もしくはエステル結合を分子内に含んだものである。ここに記載したエポキシ樹脂がないと特定の溶剤に浸漬した際に大きく膨潤し、工程中でシートが剥離してしまうという問題が発生する。 The base resin constituting the base layer is a composite of an epoxy resin and a curing agent, the epoxy resin has a triazine skeleton, and the curing agent contains an ether bond or an ester bond in the molecule. Without the epoxy resin described here, there is a problem that the sheet swells greatly when immersed in a specific solvent and the sheet peels off during the process.

粘着層を構成する粘着樹脂は、シリコーンとビスフェノールA型エポキシ樹脂の共重合体と、エーテル結合もしくはエステル結合を分子内に含む硬化剤の複合体であり、シリコーンは粘着樹脂の35〜65質量%であり、ビスフェノールA型エポキシ樹脂は粘着樹脂の末端部に配置されたものである。ここに記載したエポキシ樹脂がないと室温での電子部品に対する接着性を発現することができず、また加熱後にその接着性を維持できないという問題が発生する。 The adhesive resin constituting the adhesive layer is a composite of a copolymer of silicone and bisphenol A type epoxy resin and a curing agent containing an ether bond or an ester bond in the molecule, and the silicone is 35 to 65% by mass of the adhesive resin. The bisphenol A type epoxy resin is disposed at the end of the adhesive resin. Without the epoxy resin described here, there is a problem that adhesion to electronic components at room temperature cannot be exhibited, and that the adhesion cannot be maintained after heating.

硬化剤の添加量は、少ないとエポキシ樹脂硬化が発揮されない傾向にあり、多いと反応しない硬化剤が系内に残ってしまう傾向にある。そのため、粘着層のエポキシ樹脂100質量部に対する硬化剤の添加量の下限は、好ましくは3質量部以上、より好ましくは6質量部以上であり、上限は好ましくは40質量部以下、より好ましくは26質量部以下である。基材層の硬化剤の添加量の下限は、好ましくは40質量部以上、より好ましくは50質量部以上であり、上限は好ましくは220質量部以下、より好ましくは120質量部以下である。 When the addition amount of the curing agent is small, the epoxy resin curing tends not to be exhibited, and when the addition amount is large, the non-reactive curing agent tends to remain in the system. Therefore, the lower limit of the addition amount of the curing agent with respect to 100 parts by mass of the epoxy resin of the adhesive layer is preferably 3 parts by mass or more, more preferably 6 parts by mass or more, and the upper limit is preferably 40 parts by mass or less, more preferably 26. It is below mass parts. The lower limit of the addition amount of the curing agent in the base material layer is preferably 40 parts by mass or more, more preferably 50 parts by mass or more, and the upper limit is preferably 220 parts by mass or less, more preferably 120 parts by mass or less.

基材樹脂には炭素繊維が含有され、炭素繊維の炭素繊維長が100μm以下、かつ、「炭素繊維長/炭素繊維の直径」の値が100以上であることが好ましく、このように炭素繊維長と炭素繊維の直径の比が大きいフィラーを添加することで、フィラー同士の接触がおおくなり、導電性をえるための分散が容易となる。添加量は好ましくは0.05質量%以上5質量%以下、より好ましくは0.5質量%以上1質量%以下であり、フィラーの添加量が少ないと表面抵抗率が大きくなる傾向にあって、場合によっては必要な導電性が得られなくなる。導電性フィラーの添加量が多いと粘度の増加によって基材層の形成、言い換えれば、シート状に形成することができなくなるという問題や、シートの透明性が著しく低下するなどの問題が発生する。 The base resin contains carbon fibers, the carbon fiber length of the carbon fibers is preferably 100 μm or less, and the value of “carbon fiber length / carbon fiber diameter” is preferably 100 or more. By adding a filler having a large diameter ratio of carbon fiber, contact between the fillers is increased, and dispersion for obtaining conductivity is facilitated. The addition amount is preferably 0.05% by mass or more and 5% by mass or less, more preferably 0.5% by mass or more and 1% by mass or less. When the addition amount of the filler is small, the surface resistivity tends to increase, In some cases, necessary conductivity cannot be obtained. When the amount of the conductive filler added is large, problems such as formation of a base material layer due to an increase in viscosity, in other words, a sheet cannot be formed, and the transparency of the sheet is significantly reduced.

保護シートの耐薬品性を評価する際の溶剤として、メチルアルコール、エチルアルコール、イソプロピルアルコール、N−メチル−2−ピロリドン、エチレングリコールモノメチルエーテル、エチレングリコールモノエチルエーテル、エチレングリコールモノブチルエーテルジエチレングリコールモノエチルエーテル、プロピレングリコールモノメチルエーテル、プロピレングリコールモノメチルエーテルアセテート、ジメチルスルホキシド、モノエタノールアミン、テトラメチルアンモニウムハイドロキサイドと水の混合溶媒、テトラメチルアンモニウムハイドロキサイドと水及びジメチルスルホキシドの混合溶媒から選ばれるいずれか一種以上が用いられる。 As solvents for evaluating the chemical resistance of protective sheets, methyl alcohol, ethyl alcohol, isopropyl alcohol, N-methyl-2-pyrrolidone, ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, ethylene glycol monobutyl ether diethylene glycol monoethyl ether , Propylene glycol monomethyl ether, propylene glycol monomethyl ether acetate, dimethyl sulfoxide, monoethanolamine, a mixed solvent of tetramethylammonium hydroxide and water, a mixed solvent of tetramethylammonium hydroxide, water and dimethyl sulfoxide One or more are used.

導電性シートを形成する組成物に、補強材としてガラスクロスやアラミド繊維や無機フィラーを添加することにより、シート強度を向上することができる。 By adding a glass cloth, an aramid fiber, or an inorganic filler as a reinforcing material to the composition forming the conductive sheet, the sheet strength can be improved.
