Description
[融点]
パーキンエルマー社製DSC にて測定した。
[充填圧力]
図1に示すFPCコネクターモデル型(ピッチ0.5mmピッチ、高さ1.16mm、最小肉厚0.12mm)を用い、下記条件で成形を行い、成形品が充填する最小の圧力を測定した。充填圧力が低いほど流動性に優れた材料であるといえる。
(成形条件)
・成形機;FANUC ROBOSHOT α-50C
・金型温度;80℃
・シリンダー温度;370℃−370℃−360℃−350℃(実施例1〜4、比較例1〜3)
350℃−350℃−340℃−330℃(比較例4)
330℃−330℃−320℃−310℃(比較例5)
300℃−300℃−290℃−280℃(比較例6)
・射出速度;200mm/sec
・保圧力;49MPa
・保圧時間;1sec
・冷却時間;5sec
・スクリュー回転数;150rpm
・スクリュー背圧;4MPa
[ガラス繊維の重量平均長さの測定]
樹脂組成物ペレット5gを600℃で2時間加熱し、灰化した。灰化残渣を5%ポリエチレングリコール水溶液に十分分散させた後、スポイトでシャーレに移し、顕微鏡でガラス繊維を観察した。同時に画像解析装置((株)ニレコ製 LUZEX FS)を用いてガラス繊維の重量平均長さを測定した。尚、画像解析の際には、重なり合った繊維を別々の繊維に分離し、それぞれの長さを求めるようなサブルーチンを適用した。尚、10μm以下のガラス繊維は除外して測定している。
[曲げ試験]
ISO178に準拠し、曲げ強度の測定を行った。
[ブリスター試験]
長さ124mm、幅12mm、厚み0.8mmの成形品を以下の条件で成形し、ブリスター評価用試験片とした。得られた試験片を任意の温度のシリコーンオイル中に5分間浸漬した後、表面を観察した。表面に膨れが出ない最大の温度をBlister Free Temp.(BFT)とした。この温度が高いほど耐熱性が高いといえる。
(成形条件)
・成形機;日鋼J75SSII−A
・金型温度;90℃
・シリンダー温度;370℃−370℃−360℃−350℃(実施例1〜4、比較例1〜3)
350℃−350℃−340℃−330℃(比較例4)
330℃−330℃−320℃−310℃(比較例5)
300℃−300℃−290℃−280℃(比較例6)
・射出速度;2.3m/sec
・保圧力;46MPa
・保圧時間;7sec
・冷却時間;27sec
・スクリュー回転数;100rpm
・スクリュー背圧;4MPa
また、実施例・比較例で使用した液晶性ポリエステルは以下の通り、調製・準備した。
(液晶性ポリエステル−1)
撹拌機、還流カラム、モノマー投入口、窒素導入口、減圧/流出ラインを備えた重合容器に、以下の原料モノマー、金属触媒、アシル化剤を投入した。
・(I)2−ヒドロキシ−6−ナフトエ酸166g(48モル%)(HNA)
・(II)テレフタル酸76g(25モル%)(TA)
・(III) 4,4'−ジヒドロキシビフェニル86g(25モル%)(BP)
・(IV)4−ヒドロキシ安息香酸5g(2モル%)(HBA)
・酢酸カリウム触媒(触媒量)
・無水酢酸(HNA、BP、HBAの総モル量に対して1.1倍モル)
次いで、窒素気流下、140℃で1時間撹拌後、撹拌を続けながら360℃まで5.5時間かけて昇温した。次に、30分かけて5Torr(即ち667Pa)まで減圧にし、酢酸等の低沸分を留出させながら溶融重合を行った。撹拌トルクが所定の値に達した後、窒素を導入して加圧状態とし、重合容器の下部からポリマーを排出し、ストランドをペレタイズしてペレット化した。得られたペレットを窒素気流下、300℃で8時間熱処理したものを液晶性ポリエステル−1とした。液晶性ポリエステル−1の融点は352℃であった。
(液晶性ポリエステル−2(比較品))
液晶性ポリエステル−2として、ポリプラスチックス(株)製ベクトラE950iを使用した。
