Description
該アクリル系共重合体(A)が、エポキシ基非含有(メタ)アクリル酸エステルモノマー(a)65〜75質量%、アクリロニトリルモノマー(b)20〜35質量%及びエポキシ基含有(メタ)アクリル酸エステルモノマー(c)1〜10質量%を共重合させたものであり、
該エポキシ樹脂用硬化剤が、平均粒子径0.5〜15μmの有機酸ジヒドラジド粒子である熱硬化性接着組成物を提供する。なお、本明細書において、「(メタ)アクリル」なる用語は、「メタクリル又はアクリル」という意味で用いている。
熱硬化性接着層形成用塗料を、基材フィルム上に塗布し、乾燥することにより熱硬化性接着層を形成する工程
を含んでなる製造方法を提供する。
まず、本発明の熱硬化性接着組成物をメチルエチルケトン、トルエン等の有機溶剤に塗布法に応じた粘度となるように投入し、エポキシ樹脂用硬化剤(C)を有機溶剤中に分散させ、他方アクリル共重合体(A)及びエポキシ樹脂(B)を有機溶剤中に溶解させることにより熱硬化性接着層形成用塗料を調製する。この場合、室温下で全有機酸ジヒドラジド粒子の70質量%が熱硬化性接着層形成用塗料中に固体粒子として分散していることが好ましい。熱硬化性接着シートの常温保管性を高めるためである。
次に、熱硬化性接着層形成用塗料を、基材フィルム上にバーコーター、ロールコーターにより乾燥厚が10〜50μmとなるように塗布し、常法により乾燥することにより熱硬化性接着層を形成する。これにより熱硬化性接着シートを得ることができる。
(1)アクリル系共重合体の調製
表1及び表2に示したモノマーからなるアクリル系共重合体を用意した。これらのアクリル系共重合体の重量平均分子量を表1及び表2に示した。
得られたアクリル系共重合体溶液に、表1及び表2の配合割合でエポキシ樹脂(B)及びエポキシ樹脂用硬化剤(C)として有機酸ジヒドラジドとを添加し、均一に混合することにより熱硬化性接着組成物として、熱硬化性接着層形成用塗料を調製した。得られた塗料の粘度をB型粘度計により測定し、表1及び表2に示した。
得られた熱硬化性接着層形成用塗料を、剥離処理が施されたポリエチレンテレフタレートフィルムに塗布し、50〜130℃の乾燥炉中で乾燥し、35μm厚の熱硬化性接着層を形成することにより、熱硬化性接着シートを作成した。
上述の熱硬化性接着シートの作製の際、熱硬化性接着層形成用塗料の塗布性について、以下の基準に従って評価した。得られた評価結果を表1及び表2に示す。
A:塗布中に筋は引かないが、乾燥後のフィルムに硬化剤粒子が観察される場合
B:塗布筋があり、厚みも不均一である場合
C:溶液がゲル状となり、塗布が不可能な場合
得られた直後の熱硬化性接着シートを所定の大きさの短冊(5cm×10cm)にカットし、その熱硬化性接着層を、175μm厚のポリイミドフィルム(175AH、カネカ(株)製)に80℃に設定したラミネーターで仮貼りした後、基材フィルムを取り除いて熱硬化性接着層を露出させた。露出した熱硬化性接着層に対し、同じ大きさの50μm厚のポリイミドフィルム(200H、デュポン社)を上から重ね合わせ、170℃で2.0MPaの圧力で60秒間加熱加圧した後、140℃のオーブン中に60分間保持した。
*4:グリシジルメタクリレート、*5:2−ヒドロキシエチルメタクリレート、*6:アクリル酸、
*7:アジピン酸ジヒドラジド、*8:7,11−オクタデカジエン−1,18−ジカルボヒドラジド
*9:jER828、ジャパンエポキシレジン社、*10:jER154、ジャパンエポキシレジン社
実施例1〜7の熱硬化性接着シートは、アクリル系共重合体(A)が、エポキシ基非含有(メタ)アクリル酸エステルモノマー(a)65〜75質量%、アクリロニトリルモノマー(b)20〜35質量%及びエポキシ基含有(メタ)アクリル酸エステルモノマー(c)1〜10質量%を共重合させたものであり、エポキシ樹脂用硬化剤が、平均粒子径0.5〜15μmの有機酸ジヒドラジド粒子であるので、塗布性も初期剥離強度、常温保管特性も満足のいくものであった。
実施例1〜10及び比較例2〜8の熱硬化性接着シートを使用して以下に説明するように補強フレキシブルプリント配線板を作製した。
短冊(2cm×2cm)にカットした熱硬化性接着シートの熱硬化性接着層を、175μm厚のポリイミドフィルム(アピカル175AH、カネカ(株)製)に80℃に設定したラミネーターで仮張りした後、剥離基材を取り除いて熱硬化性接着層を露出させた。露出した熱硬化性接着層に対し、同じ大きさの厚さ50μm厚のポリイミドフィルム(カプトン200H、デュポン社製)を上から重ね合わせ、170℃で2.0MPaの圧力で60秒間加熱加圧した後、140度のオーブン中で60分間保持した。その後、加熱硬化した試験片を40℃、90%RHの湿熱オーブン中で96時間放置した。
