Abstract
Description
一般式(1)
1.ポリカーボネート樹脂(A):
(住化ポリカーボネート社製 SDポリカ200−13、粘度平均分子量21000)
(日東紡績社製 NEガラス繊維、長径28μm、短径7μm、繊維長3mm、
エポキシ/ウレタン系集束剤、
1GHzの誘電率4.8、1GHzの誘電正接0.0015)
ビス(2,4−ジ−tert−ブチル−4−メチルフェニル)ペンタエリスリトールジフォスファイト(IUPAC名:3,9−ビス(2,6−ジ−tert−ブチル−4−メチルフェノキシ)−2,4,8,10−テトラオキサ−3,9−ジホスファスピロ[5,5]ウンデカン)
ペンタエリスリトールステアレート
ロキシオールVPG861(商品名、コグニス社製、以下、「D1」と略記)
前述の各種配合成分を表1に示す配合比率にて、二軸押出機(東芝機械社製TEM−37SS)を用いて、溶融温度300℃にて混練し、ガラス繊維強化ポリカーボネート樹脂組成物を得た。具体的には、ポリカーボネート樹脂、亜リン酸エステル系化合物、脂肪酸エステルを第一フィーダー(原料供給口)から押出機バレル内に供給し、樹脂組成物を十分に溶融した後に、低誘電ガラス繊維を第二フィーダー(充填剤供給口)から押出機バレル内に供給した。
得られた各種樹脂組成物のペレット及び曲げ弾性率(剛性)を測定した試験片をジクロロメタンに溶解し、No.1濾紙を用いて溶解液中の不溶物をろ過した。この濾液をドライアップし、得られたポリマーの一定量(0.25g)をジクロロメタン50mlに溶解した。キャノン・フェンスケ粘度計を用いてジクロロメタン希薄溶液の粘度を23℃で測定し、シュネルの式を用いて各試験片の粘度平均分子量を求めた。
(シュネルの式) [η]=1.23×10−4・M0.83
[η]:固有粘度、M:粘度平均分子量
なお、熱安定性の指標である分子量低下は、ペレットの粘度平均分子量から試験片の粘度平均分子量を減じた値(ΔMv)が、1000未満を良好(表中「◎」で示す)、1000以上2000未満を使用可(表中「○」で示す)、2000以上を不良(表中「×」で示す)とした。
得られた各種樹脂組成物のペレットをそれぞれ125℃で4時間乾燥した後に、射出成型機(ファナック株式会社製、ROBOSHOT S2000i100B)を用いて、シリンダー設定温度300℃、金型温度50℃、冷却時間20秒の条件にて、離型性を評価した。金型には、コップ型の離型抵抗金型(成形品の形状:直径70mm、高さ20mm、厚み4mm)を用いて、カップ型成形品を成形する際の突き出しピンにかかる突き出し荷重を測定し、離型抵抗値を求めた。評価の基準として、離型抵抗値が800N未満を使用可(表中「○」で示す)、800N以上を不良(表中「×」で示す)とした。
得られた各種樹脂組成物のペレットをそれぞれ125℃で4時間乾燥した後に、射出成型機(ファナック株式会社製、ROBOSHOT S2000i100B)を用いて設定温度300℃、射出圧力100MPaにてISO試験法に準じた厚み4mmの試験片を作製し、得られた試験片を用いてISO 178に準じ曲げ弾性率(剛性)を測定した。曲げ弾性率が、6000MPa以上を使用可(表中「○」で示す)、6000MPa未満を不良(表中「×」で示す)とした。
得られた各種樹脂組成物のペレットをそれぞれ125℃で4時間乾燥した後に、射出成型機(ファナック株式会社製、ROBOSHOT α−S150iA)を用いて設定温度320℃、射出圧力90MPaにて120mm×120mm×厚み3.2mmの試験片を作製した。得られた試験片を用いて自由空間法により、周波数28GHzにおける誘電率および誘電正接を測定した。周波数28GHzにおける誘電率が、3.5未満を良好(表中「○」で示す)、3.5以上を不良(表中「×」で示す)とした。また、周波数28GHzにおける誘電正接が、0.01未満を良好(表中「○」で示す)、0.01以上を不良(表中「×」で示す)とした。
Claims (10)
