Abstract
Description
1.分子量
ポリオレフィン樹脂の分子量は、ポリマーラボラトリー(Polymer Laboratory)社製の高温GPC(Gel Permeation Chromatography)を利用して、1,2,4‐トリクロロベンゼン(TCB)を溶媒として140℃で測定し、分子量測定の標準試料としてはポリスチレンを利用した。
ポリオレフィン系樹脂の融点(Tm)は、示差走査熱量測定(DSC、メトラートレド(Mettler Toledo)社製、DSC‐822E)で分析した。ポリオレフィン系樹脂と耐熱性樹脂の分析条件は、サンプル重量5mgを走査速度10℃/minで樹脂が完全に融解するまで昇温した後、その温度で10分間維持して完全な溶融状態にした後、走査速度10℃/minで0℃に降温して完全な固体状態に結晶化した後、また走査速度10℃/minで昇温して樹脂の融点を決定した。
TESA社製のTESA Mu-Hite electronic Height Gaugeを利用して、測定圧力を0.63Nとし、最終製品の厚さを測定した。
Instron社製のUTM(universal testing machine)に直径1mm、曲率半径0.5mmのピンを装着し、23℃の温度で120mm/minの移動速度で多孔膜を破断する際の多孔膜の強度を測定した。厚さで標準化された値をN/μmで表記した。
ガス透過度は、空隙測定装置(porometer:PMI社製、CFP‐1500‐AEL)で測定した。一般的に、ガス透過度は、ガーレー数で表示されるが、ガーレー数は、多孔膜の厚さの影響が補正されず、多孔膜自体の空隙構造による相対的な透過度が分かりにくい。これを解決するために、本発明では、ダルシー透過定数を使用した。ダルシー透過定数は、下記の数学式から得られ、本発明では窒素を使用した。
ここで、C:ダルシー透過定数
F:流速
T:サンプルの厚さ
V:ガスの粘度(0.185 for N2)
D:サンプルの直径
P:圧力
本発明では、100〜200psiの領域でダルシー透過定数の平均値を使用した。
複合多孔膜を10cm×10cmに裁断した後、テフロンフィルムの間に入れてサイズが11cm×11cmであり、厚さが3mmであるガラス板の間に入れて、150℃に温度安定化が行われたオーブン(JEIO TECH社製、OF‐12GW)に入れて60分間放置した後、サイズ変化を測定して収縮率を算出した。収縮率の算出は、下記の式1に従った。
収縮率(%)=100×(100mm−150℃放置後の長さ)/100mm
20時間以上連続して生産する際、単位時間(1hr)当たり熱処理工程後、基材多孔膜良品生産量(m2/hr)と熱処理工程が完了した多孔膜にコーティングを実施して製造された複合多孔膜良品生産量(m2/hr)の割合を使用した。生産性の算出は、下記の式2を利用した。同じ基準で比較するために、本発明による製造方法と非連続式製造方法で熱処理工程が行われた膜(コーティング前の基材多孔膜)の単位時間当り生産量を基材多孔膜生産量とした。具体的に、巻き取られるロール交替による損失、非連続式工程で発生する損失などは、基材多孔膜の生産量に含まれるが、複合多孔膜の生産量からは除外される。
生産性(%)=(複合多孔膜の生産量(m2/hr))/(基材多孔膜の生産量(m2/hr))×100
ポリオレフィン系樹脂として、重量平均分子量が3.0×105であり、融点が135℃である高密度ポリエチレンを使用し、ダイリューエントとしては、40℃で動粘度が160cStであるパラフィンオイルを使用した。ポリオレフィン系樹脂とダイリューエントの組成比は、28重量%及び72重量%とした。
ポリオレフィン系樹脂として重量平均分子量が3.8×105であり、融点が135℃である高密度ポリエチレンを使用し、ダイリューエントとしては、40℃で動粘度が160cStであるパラフィンオイルを使用した。ポリオレフィン系樹脂とダイリューエントの組成比は、33wt%と67wt%とした。
重量平均分子量が1.5×105であり、融点が134℃である高密度ポリエチレンを一軸押出機を利用して200℃で押出し、Tダイとキャスティングロールを利用してフィルムを製造した。このフィルムをロールタイブの延伸機を利用して、常温で1.5倍に冷延伸を実施し、110℃で2.2倍に熱延伸を実施し、120℃で熱固定を実施して、乾式法で基材多孔膜を製造した。この際、製造された基材多孔膜の幅は500mmであり、その生産速度は5m/minであり、コーティング実施後の製品の長さが500mになるように、530mの単位でロールを交替した。ワインディングが終了したロールを新たなロールに交替する過程で20mの製品損失が発生した。前記方法で製造された基材多孔膜をコーティング設備に移送し、巻出機を利用して巻き出し、コーティングを実施した。
ポリオレフィン系樹脂として重量平均分子量が3.0×105であり、融点が135℃である高密度ポリエチレンを使用し、ダイリューエントとしては、40℃で動粘度が160cStであるパラフィンオイルを使用した。ポリオレフィン系樹脂とダイリューエントの組成比は、30wt%と70wt%とした。
