摘要: | 本研究從事Metallocene polyethylene-octene elastomer mPE(M)/mPE(M)-g-silane 20phr與mPE(M)/mPE(M)-g-silane 20phr之合膠材料之製備(M: medium crystallinity, L: low crystallinity),使用DCP(Dicumyl peroxide)為起始劑,DBTL(Dibutyin Dilaurate)作為催化劑,VTEOS (Vinyl Triethoxy Silane)當交聯劑,使用不同型號的mPE為相容劑。以70℃水浴進行水交聯後,測量熱性質與機械性質。利用剝離測試,測量合膠材料對於射出製程中常用PET膜的極性,發現純的mPE對於PET膜的極性並不高,主要的極性來源silane;加入黏土後,部分silane與黏土作用,所以極性降低。因此,適當的調整配方比例有其必要性。
Metallocene polyethylene-octene elastomer (mPE) blends are obtained and studied by using mPE (M)-g-silane and mPE (L)-g-silane as the adhesion promoters (M: medium crystallinity, L: low crystallinity). First, two different types of metallocene polyethylene-octene were grafted with vinyl triethoxy silane, then followed by the mixing those materials with mPE (M). The crosslinking reaction was conducted in water at 70℃. The polarity of those materials is mainly from silane. If the contents of clay were increased, a part of silane would react with clay and the polarity of those materials would decrease, instead. Overall, the mechanical properties reached the prescribed requirement.. |
