Description

無鹵無磷樹脂配方及由該樹脂配方製備之無鹵無磷低介電耐燃複合材料
本發明係有關於一種樹脂配方,特別是有關於一種無鹵無磷樹脂配方及由該樹脂配方製備之無鹵無磷低介電耐燃複合材料。
在無鹵材料配方組成中,一般以選擇磷化物當作耐燃劑,取代現有鹵素化合物,但由於含磷量不可偏高,致造成耐熱性不足。因此,選擇適當含磷量配方組成,搭配氫氧化鋁來達成UL-94 V0耐燃需求。目前,即使無鹵無磷型高耐熱配方組成亦使用氫氧化鋁來達成UL-94 V0耐燃需求,例如US 2006/0084787A1 “Novel cyanate ester compound,flame-retardant resin composition,and cured product thereof”以及US 2008/02621397A1 “Flame retardant crosslink agent and epoxy resin compositions free of halogen and phosphorous”。在有機高耐熱基板材料的選擇上,除了BT(Bismaleimide Triazine)樹脂外,目前,以環氧樹脂為主要的耐熱性材料,以TMA測量所得到的Tg皆在180℃左右。
本發明之一實施例,提供一種無鹵無磷樹脂配方,係由下列方法所製備:混合羧酸酐(carboxy anhydride)衍生物、二異氰酸酯、苯乙烯馬來酸酐(styrene maleic anhydride,SMA)共聚衍生物與一溶劑,以形成一混合物;以及加熱該混合物,以形成一樹脂配方。
本發明之一實施例,提供一種無鹵無磷低介電耐燃複合材料,係由下列方法所製備:提供上述之無鹵無磷樹脂配方;以及將該樹脂配方含浸纖維並加熱硬化,以製備一無鹵無磷低介電耐燃複合材料。
本發明複合材料為一種環保型(無鹵無磷)高耐熱低介電材料,主要由羧酸酐(carboxy anhydride)衍生物、例如二異氰酸二苯甲烷(methylene diphenyl diisocyanate,MDI)、二異氰酸甲苯(toluene diisocyanate,TDI)或二異氰酸異佛爾酮(isophorone diisocyanate,IPDI)的二異氰酸酯與苯乙烯馬來酸酐(styrene maleic anhydride,SMA)共聚衍生物等原料所構成,其Tg超過180℃,且不須額外添加例如氫氧化鋁的填充劑(filler)即可達到UL-94 V0耐燃需求,對未來高耐熱及高頻基板材料的開發有相當助益。
本發明主要將高氮含量之二異氰酸酯單體(例如MDI、TDI或IPDI)、羧酸酐單體(例如TMA)與樹脂(例如SMA)混合攪拌進行反應,並控制適當的反應物比例及溫度,以合成此無鹵無磷低介電耐燃複合材料。
為讓本發明之上述目的、特徵及優點能更明顯易懂,下文特舉一較佳實施例,作詳細說明如下:
本發明之一實施例,提供一種無鹵無磷樹脂配方,其由下列方法所製備。首先,混合羧酸酐(carboxy anhydride)衍生物、二異氰酸酯、苯乙烯馬來酸酐(styrene maleic anhydride,SMA)共聚衍生物與一溶劑,以形成一混合物。之後,加熱混合物,以形成一樹脂配方。
上述羧酸酐衍生物具有下列化學式:
化學式中,A可為苯環或環己烷,R可為H、CH3 或COOH,n可為0~8。本發明羧酸酐衍生物較佳為苯三甲酸酐(trimellitic anhydride,TMA)。
上述二異氰酸酯可包括二異氰酸二苯甲烷(methylene diphenyl diisocyanate,MDI)、二異氰酸甲苯(toluene diisocyanate,TDI)或二異氰酸異佛爾酮(isophorone diisocyanate,IPDI),較佳為二異氰酸二苯甲烷(MDI)。
上述苯乙烯馬來酸酐共聚衍生物具有下列化學式:
化學式中,m可為1~7,較佳為2~3,n可為2~15。
上述溶劑可包括二甲基甲醯胺(DMF)、甲基咯烷酮(NMP)或二甲基亞碸(DMSO)。
上述混合物中,羧酸酐衍生物在混合物固含量(solid content)中之重量百分比大體介於10~30%,二異氰酸酯在混合物固含量中之重量百分比大體介於10~35%,苯乙烯馬來酸酐共聚衍生物在混合物固含量中之重量百分比大體介於35~80%。上述溶劑在混合物中之重量百分比大體介於20~60%。
上述加熱混合物之溫度大體介於攝氏80~140度,較佳介於攝氏95~110度。
本發明之一實施例,提供一種無鹵無磷低介電耐燃複合材料,其由下列方法所製備。首先,提供上述之無鹵無磷樹脂配方,之後,將樹脂配方含浸纖維並加熱硬化,即可得到無鹵無磷低介電耐燃複合材料。
上述纖維可包括玻璃纖維布或聚醯胺纖維。

本發明主要將高氮含量之二異氰酸酯單體(例如MDI、TDI或IPDI)、羧酸酐單體(例如TMA)與樹脂(例如SMA)混合攪拌進行反應,並控制適當的反應物比例及溫度,以合成此無鹵無磷低介電耐燃複合材料。
