Description
単一成形体の場合は、部材とその成形体とがシリコーン系組成物とで接着されていたり、部材と熱可塑性樹脂成形体はネジ止め等で結合され周囲をシリコーン系組成物で覆われていたり、容器状の成形体中に部材が収納されシリコーン系組成物でポッティングされていても良い。
先ず、本発明の第一実施形態の概略について図を用いて説明する。
熱可塑性樹脂成形体は、ポリブチレンテレフタレート樹脂、リン化合物、その他の含有可能な成分(その他の成分)を含む。
付加反応型シリコーン系組成物の特徴の一つとして、耐熱性に優れることが挙げられる。熱可塑性樹脂として、耐熱性の高いものを選択すれば、耐熱性に優れた一体成形体になり、付加反応型シリコーン系組成物の特徴も充分に活かすことができる。このような観点から、熱可塑性樹脂としては、耐熱性に優れ、難燃剤等の様々な添加剤と好適に組み合わせ可能なポリブチレンテレフタレート樹脂を用いる。
リン化合物の中でも、5価以外のリン化合物は、付加反応型シリコーン系接着剤の硬化を特に阻害しやすい。5価以外のリン化合物としては、3価のリン化合物が用いられる場合が多い。3価のリン化合物は、例えば酸化防止剤として熱可塑性樹脂に添加され、樹脂成形体の酸化劣化を防止することができる。また、ポリブチレンテレフタレート等のポリエステル樹脂のエステル交換を抑制する効果が高く、3価のリン化合物を添加して得られた組成物はより高い熱安定性を示す。
樹脂成形体は、上記の熱可塑性樹脂、リン化合物以外に、無機充填剤、酸化防止剤、顔料等の従来公知の添加剤を、本発明の効果を害さない範囲で添加できる。特に、無機充填剤の一種であるガラス繊維を使用すると、樹脂成形体の機械強度や耐熱性が高まるため好ましい。
付加反応型シリコーン系組成物は、室温又は加熱により硬化する組成物であり、従来公知のものを使用することができる。硬化は、白金系触媒による付加反応で進行する。
部材は特に限定されず、センサー、自動車用・家電用のハイブリッドIC、半導体部品等の電子部品の他に、他の樹脂成形体であってもよい。部材が電子部品の場合には、接着、ポッティングのいずれの用途も一般的である。樹脂成形体の場合には、主に上記熱可塑性樹脂成形体との接合のために、付加反応型シリコーン系組成物が使用される。ここで、樹脂成形体は、どのような樹脂からなるものであってもよく、具体的には、熱可塑性樹脂、熱硬化性樹脂のいずれからなるものであってもよい。
ポリブチレンテレフタレート樹脂(PBT):ウィンテックポリマー社製、商品名「ジュラネックス300FP」(固有粘度0.69)
リン化合物2:ビス(2,4−ジ−t−ブチルフェニル)ペンタエリスリトールジホスファイト、ADEKA社製、商品名「アデカステブPEP−24G」
表1に示す配合(単位は質量%)で、PBT、リン化合物及びガラス繊維を二軸押出機にて溶融混練(シリンダー温度260℃、スクリュー回転数130rpm、押出量15kg/hr)しペレットを作製後、得られたペレットを140℃、3時間乾燥した後に、射出成形機(ファナック社製S2000i 100B)に投入し、後述する接着強度の測定に使用する樹脂試験片(ISO3167に準拠した多目的試験片)を作製した。このISO3167に準拠した試験片の中央部を切断し、一方を第一熱可塑性樹脂成形体とし、他方を第二熱可塑性樹脂成形体とした。
図3(a)に示すように、第一樹脂成形体に7mm×7mmの穴を開けた日東電工株式会社製ニトフロン粘着テープ(厚み0.18mm)を貼り付け、穴の部分にシリコーン系接着剤を塗布した。塗布後、第二樹脂成形体を重ね合わせ、クリップで固定し、120℃×0.5時間の条件で接着を行った。実施例及び比較例の一体成形体が得られた。
接合体を23℃、50%RHの環境に24時間以上放置し、オリエンテック製万能試験機テンシロンRTC−1325PLを用いて押し剥がし試験速度5mm/minの条件で接着した第二樹脂成形体を押し剥がし(具体的には、図3(b)の白抜き矢印の方向に圧力を加えて押し剥がした。)、押し剥がし強度の最高値を測定した。測定結果は表1に示した。
