- the glass transition temperature of the resin forming the non-adhesive resin layer in Example 2 in which the curing agent is blended is 90.
- the probe tack of the non-adhesive resin layer is 6 to 30 kN / m 2 , it exhibits appropriate adhesiveness, so the workability of the heat conductive sheet is good. It turns out that it becomes.
- Example 1 since the glass transition point Tg of the resin forming the non-adhesive resin layer was high, the reworkability after high temperature storage was extremely good.
- Example 3 in Comparative Example 1 in which no curing agent was blended, the reworkability after high-temperature storage was inferior, and the probe tack of the non-adhesive resin layer exceeded 30 kN / m 2 and the comparison without the non-adhesive resin layer In Example 3, it can be seen that the workability is inferior because appropriate tackiness cannot be obtained.
- the adhesive heat conductive layer and the non-adhesive resin layer are laminated, and the tack property of the non-adhesive resin layer is an appropriate size lower than the tack property of the adhesive heat conductive layer. Therefore, the workability at the time of assembling the electronic component and the heat sink using the heat conductive sheet is improved, and the reworkability of disassembling and reassembling the once assembled product after long-term use is also improved.

本発明の熱伝導性シートでは、粘着性熱伝導層と非粘着性樹脂層が積層している。
表1に示した樹脂、硬化剤及び難燃性フィラーをトルエン:メチルエチルケトン=1:1(質量比)の混合溶剤にて、固形分10質量%に調製し、バーコーターでPETフィルムに塗布し、90℃で1分間乾燥させ、さらに140℃で5分間乾燥させて表1に示す塗布厚の非粘着性樹脂層を形成した。なお、表1において、「部」は質量部を意味する。難燃性フィラーとして用いたメラミンシアヌレート(堺化学工業製 STABIACE MC-5S)の平均粒子径は約1μmである。
上述の実施例2において、非粘着性樹脂層に配合する硬化剤として、イミダゾール系硬化剤に代えて、イソシアネート系硬化剤(コロネートL、日本ポリウレタン工業)を12部使用することにより実施例3の熱伝導性シートを製造し、又はヒドラジド系硬化剤(UHD、味の素ファインテクノ)を12部使用することにより実施例4の熱伝導性シートを製造した。
各実施例及び比較例の熱伝導性シートについて、(a)非粘着性樹脂層のタック性、(b)非粘着性樹脂層の外観、(c)熱伝導性シートの熱伝導率、(d)熱伝導性シートを高温環境で保存した後のリワーク性、を次のように評価した。実施例1,2及び比較例1~3について、結果を表1に示す。実施例3、4は、実施例2と同様の結果が得られた。
タック性試験機として、RHESCA社製タッキング試験機TAC-IIを使用し、非粘着性樹脂層に、温度40℃、直径5mmのアルミニウム製円柱状プローブを、押しつけ速度30mm/min、引き剥がし速度120mm/min、荷重196g、押しつけ時間5.0秒、引っ張り距離5mm、プローブ加熱40℃、シートステージ加熱40℃の条件で押しつけて引き剥がしたときのプローブタックを測定した。なお、比較例3では、非粘着性樹脂層がないため、粘着性熱伝導層のタック性を測定した。そして、プローブタックの測定値により、次の基準で評価した。
過小:6kN/m2未満
良:6~30kN/m2
過大:30kN/m2超
非粘着性樹脂層の外観を目視観察し、次の基準により評価した。

B:斜光観察でムラが見られる
C:塗膜にハジキが見られる
熱伝導シートの厚み方向の熱伝導率をASTM D-5470準拠の熱伝導率計(ソニー製)により測定した(ヒーター出力 8W、シート面圧 1kgf/cm2)。
アルミ板に、熱伝導性シートを、その非粘着性樹脂層面側が接触するように乗せ、125℃に設定した環境試験容器内で100時間保管し、取り出して室温に冷却し、アルミ板からシートを剥がした。このとき、熱伝導性シートの非粘着性樹脂層と粘着性熱伝導層が分離せずにアルミ板から剥がれた場合を○、分離して非粘着樹脂層がアルミ板に残った場合を×と評価した。
