Description

低介電樹脂配方、預聚合物、組成物及其複合材料與低介電樹脂預聚合物溶液的製備方法
本發明係關於一種環保樹脂,尤其是關於一種環保型高耐熱低介電樹脂配方及其應用。
在現今無鹵材料配方組成中,一般選擇磷化物當作耐燃劑以取代現有鹵素化合物,甚至因含磷量不可偏高,影響耐熱性不足,而選擇適當含磷量配方,搭配氫氧化鋁來達成UL-94 V0耐燃需求。即使無鹵無磷型配方組成,亦使用氫氧化鋁來達成UL-94 V0耐燃需求,如美國專利公開號US 2006/0084787A1”Novel cyanate ester compound,flame-retardant resin composition,and cured product thereof “,及US2008/02621397A1“Flame retardant crosslink agent and epoxy resin compositions free of halogen and phosphorous”。
在有機基板的材料選擇上,除了雙馬來亞醯胺三嗪(Bismaleimide Triazine,BT)樹脂外,目前以環氧樹脂(epoxy resin)為主的耐熱性材料,以熱機械分析儀(Thermal Mechanical Analyzer,TMA)測量所得到的Tg皆在180℃左右,因而會有耐燃不足的問題,需搭配耐燃無機粉體或耐燃樹脂,如世界專利公開號WO 03/048251”Prepreg and composition of epoxy resin(s),SMA copolymers(s) and bis-maleimide triazine resin(s)”、日本專利公開號JP 2003138241”Heat-resistant adhesive and laminate using the same adhesive-applied heatsink and adhesive-applied metallic foil”、日本專利公開號JP 2004217861”Heat-resistant adhesive and laminate using this adhesive,heat sink with adhesive,and metal foil with adhesive”。
因此,業界亟需一種能兼具環保、高耐熱性(Tg超過180℃)、以及低介電性之樹脂,以因應高頻元件的需求。
本發明提供一種低介電樹脂配方,包括:20~150重量份之二異氰酸酯(diisocyanate);20~400重量份之聚(2,6-二烷基-1,4-苯醚)(Poly(2,6-dialkyl-1,4-phenylene oxide));以及200~650重量份之溶劑。
本發明尚提供一種低介電樹脂預聚合物溶液的製備方法,包括:混合20~150重量份之二異氰酸酯(diisocyanate);20~400重量份之聚(2,6-二烷基-1,4-苯醚)(Poly(2,6-dialkyl-1,4-phenylene oxide));以及200~650重量份之溶劑以形成一低介電樹脂配方;以及加熱該低介電樹脂配方進行一預聚合反應以形成一低介電樹脂預聚合物溶液。
本發明尚提供一種低介電樹脂預聚合物,具有下列化學式I或具有下列化學式II及式III所示之重複單元:
其中,A為苯環或環己烷;X為-H、-CH3、-NCO或-CH2-NCO;Y為-NH-、-NHCO-、或-NHCOO-;Q為-CH2-、-C(CH3)2-、-O-、-S-、-SO2-或不存在;n為20~230;R3為-H、-CH3或-COOH;R1及R2為C1~C5烷基;m為0~8;y為20~230;z為1~20000;V為-NH-,-NHCO-或-NHCOO-。
本發明另提供一種低介電樹脂組成物,係由上述之低介電樹脂預聚合物溶液加熱固化而成。
本發明還提供一種低介電樹脂複合材料,包括:纖維;以及上述之低介電樹脂組成物。
