Description
技术领域
本发明涉及在小于或等于50℃的温度下为液体形式的物质组合物,它包括用下述结构表示的单官能的苯并噁嗪化合物:
其中R是选自C1-40烷基、C2-40烯基,其中各自被O、N、S、C=O、COO和NHC=O中一个或更多个任选取代或隔开,和C6-20芳基中的成员;m为0-4;和R1-R5独立地选自C1-40烷基、C2-40烯基,其中各自被O、N、S、C=O、COOH和NHC=O中一个或更多个任选取代或隔开,和C6-20芳基,且存在R1-R5中的至少一个。
背景技术
苯并噁嗪是已知的。环氧树脂和苯并噁嗪的共混物也是已知的,参见例如美国专利Nos.4607091(Schreiber)、5021484(Schreiber)、5200452(Schreiber)和5445911(Schreiber)。这些共混物表明潜在地可用于电子工业,因为环氧树脂可降低苯并噁嗪的熔体粘度,从而便于使用较高的填料负载,同时维持可加工的粘度。然而,环氧树脂有时非所需地增加苯并噁嗪聚合时的温度。
美国专利No.6620925(Musa)涉及且要求保护一种可固化组合物,它包括苯并噁嗪以外的不具有反应性官能度的一些苯并噁嗪化合物(公开了除了烯丙基和炔丙基以外的苯并噁嗪,但没有要求保护)和选自乙烯基醚、乙烯基硅烷、含乙烯基或烯丙基官能度的化合物或树脂、硫醇-烯、含肉桂基或苯乙烯基类官能度的化合物或树脂、富马酸酯、马来酸酯、丙烯酸酯、马来酰亚胺、氰酸酯和含乙烯基硅烷和肉桂基、苯乙烯基类、丙烯酸酯或马来酰亚胺官能度二者的混杂树脂中的可固化的化合物或树脂。
美国专利No.6743852(Dershem)据说涉及液体苯并噁嗪,它可与一种或更多种环氧、氰酸酯、酯、马来酰亚胺、丙烯酸酯、乙烯基醚、乙烯基酯、苯乙烯基类、炔丙基醚、二烷基酰胺、芳族乙炔、苯并环丁烯、硫醇烯、马来酸酯、噁唑啉和衣康酰亚胺结合。
环氧树脂、苯并噁嗪和酚树脂的三元共混物也是已知的。参见美国专利6207786(Ishida)和S.Rimdusit和H.Ishida,“Developmentof new class of electronic packaging materials based on ternarysystem of benzoxazine,epoxy,and phenolic resin(基于苯并噁嗪、环氧和酚树脂的一组新型电子包装材料的开发)”,Po1ymer,41,7941-49(2000)。
尽管具有这些现有技术,但苯并噁嗪化合物在小于或等于50℃的温度(例如室温)下为液体形式的独特优势如此小,如果有的话,外加的稀释剂将可用于添加、共混和/或分配用苯并噁嗪化合物制备的组合物。另外,希望提供这种苯并噁嗪化合物与额外的反应物的共混物,所产生的体系具有认为用已知可固化体系不可能实现的物理性能的平衡。
发明内容
在最宽的意义上,本发明涉及在小于或等于50℃的温度下为液体形式的物质组合物,它包括单官能的苯并噁嗪化合物。该单官能的苯并噁嗪化合物用下述结构表示:
其中R选自C1-40烷基、C2-40烯基,其中各自被O、N、s、C=O、COO和NHC=O中一个或更多个任选取代或隔开,和C6-20芳基;m为0-4;和R1-R5独立地选自C1-40烷基、C2-40烯基,其中各自被O、N、S、C=O、COOH和NHC=O中一个或更多个任选取代或隔开,和C6-20芳基,且存在R1-R5中的至少一个。
在另一方面中,本发明将具有选自氰酸酯、环氧、环硫化物、马来酰亚胺、衣康酰亚胺、桥亚甲基四氢邻苯二甲酰亚胺(nadimide)、噁唑啉、烯丙基酰胺、丙烯酸酯、甲基丙烯酸酯、乙烯基醚、乙烯基酯及其结合中的官能度的一种或更多种化合物与以上所述的单官能苯并噁嗪结合到本发明的物质组合物内。
在再一方面中,本发明将液体形式的多官能苯并噁嗪(例如以下所示的苯并噁嗪)与以上所示的单官能苯并噁嗪结合,且可任选地包括以上所述的具有选自氰酸酯、环氧、环硫化物、马来酰亚胺、衣康酰亚胺、桥亚甲基四氢邻苯二甲酰亚胺、噁唑啉、烯丙基酰胺、丙烯酸酯、甲基丙烯酸酯、乙烯基醚、乙烯基酯及其结合中的官能度的化合物。
具体实施方式
如上所述,本发明涉及在小于或等于50℃的温度下为液体形式的物质组合物,它包括单官能的苯并噁嗪化合物。该单官能的苯并噁嗪化合物用下述结构表示:
其中R选自C1-40烷基、C2-40烯基,其中各自被O、N、S、C=O、COO和NHC=O中一个或更多个任选取代或隔开,和C6-20芳基;m为0-4;和R1-R5独立地选自C1-40烷基、C2-40烯基,其中各自被O、N、S、C=O、COOH和NHC=O中一个或更多个任选取代或隔开,和C6-20芳基,且存在R1-R5中的至少一个。

当一个或更多个以上所述的“X”或“Y”基与一个或更多个以上所述的连接基配合形成附属的苯并噁嗪基时,正如本领域技术人员容易意识到的,可生产宽泛的各种有机链,例如氧基烷基、硫代烷基、氨基烷基、羧基烷基、氧基烯基、硫代烯基、氨基烯基、羧基烯基、氧基炔基、硫代炔基、氨基炔基、羧基炔基、氧基环烷基、硫代环烷基、氨基环烷基、羧基环烷基、氧基环烯基、硫代环烯基、氨基环烯基、羧基环烯基、杂环、氧杂环、硫代杂环、氨基杂环、羧基杂环、氧基芳基、硫代芳基、氨基芳基、羧基芳基、杂芳基、氧基杂芳基、硫代杂芳基、氨基杂芳基、羧基杂芳基、氧基烷基芳基、硫代烷基芳基、氨基烷基芳基、羧基烷基芳基、氧基芳基烷基、硫代芳基烷基、氨基芳基烷基、羧基芳基烷基、氧基芳基烯基、硫代芳基烯基、氨基芳基烯基、羧基芳基烯基、氧基烯基芳基、硫代链烯基芳基、氨基烯基芳基、羧基烯基芳基、氧基芳基炔基、硫代芳基炔基、氨基芳基炔基、羧基芳基炔基、氧基炔基芳基、硫代炔基芳基、氨基炔基芳基或羧基炔基芳基、氧基亚烷基、硫代亚烷基、氨基亚烷基、羧基亚烷基、氧基亚烯基、硫代亚烯基、氨基亚烯基、羧基亚烯基、氧基亚炔基、硫代亚炔基、氨基亚炔基、羧基亚炔基、氧基环亚烯基、硫代环亚烷基、氨基环亚烷基、羧基环亚烷基、氧基环亚烯基、硫代环亚烯基、氨基环亚烯基、羧基环亚烯基、氧基亚芳基、硫代亚芳基、氨基亚芳基、羧基亚芳基、氧基烷基亚芳基、硫代烷基亚芳基、氨基烷基亚芳基、羧基烷基亚芳基、氧基芳基亚烷基、硫代芳基亚烷基、氨基芳基亚烷基、羧基芳基亚芳基、氧基芳基亚烯基、硫代芳基亚烯基、氨基芳基亚烯基、羧基芳基亚烯基、氧基烯基亚芳基、硫代烯基亚芳基、氨基烯基亚芳基、羧基烯基亚芳基、氧基芳基亚炔基、硫代芳基亚炔基、氨基芳基亚炔基、羧基芳基亚炔基、氧基炔基亚芳基、硫代炔基亚芳基、氨基炔基亚芳基、羧基炔基亚芳基、杂亚芳基、氧基杂亚芳基、硫代杂亚芳基、氨基杂亚芳基、羧基杂亚芳基、含杂原子的二或多价环部分、含氧杂原子的二或多价环部分,含硫杂原子的二或多价环部分,含氨基杂原子的二或多价环部分,含羧基杂原子的二或多价环部分,和类似物。
如上所述,液体形式的多官能苯并噁嗪也可与该物质组合物结合。例如,
编号为3、9和11的双官能苯并噁嗪本身也形成本发明的一部分。
据观察,一些单官能苯并噁嗪与一些多官能苯并噁嗪的结合物是尤其理想的。例如,这三种单官能苯并噁嗪和一种多官能苯并噁嗪的结合物值得推举:
本发明也可将具有选自氰酸酯、环氧、环硫化物、马来酰亚胺、衣康酰亚胺、桥亚甲基四氢邻苯二甲酰亚胺、噁唑啉、烯丙基酰胺、丙烯酸酯、甲基丙烯酸酯、乙烯基醚、乙烯基酯及其结合中的官能度的一种或更多种化合物与以上所述的单官能苯并噁嗪,和任选地与以上所述的多官能苯并噁嗪结合到本发明的物质组合物内。
在所需的实施方案中,当使用具有这种官能度的化合物时,苯并噁嗪与具有这种官能度的化合物之比应当在2∶1-25∶1范围内,例如5∶1-15∶1,所需地10∶1-12∶1。尤其理想的具有这种官能度的化合物是氰酸酯化合物。
可参考式I的结构描述具有氰酸酯官能度的化合物:
R1-(O-C≡N)m (I)
其中m为2-5,和R1是含芳核的残基。这种化合物更具体的实例包括1,3-二氰酰基苯(dicyanatobenzene);1,4-二氰酰基苯;1,3,5-三氰酰基苯;1,3、1,4-、1,6-、1,8-、2,6-或2,7-二氰酰基萘;1,3,6-三氰酰基萘;4,4`-二氰酰基联苯;双(4-氰酰基苯基)甲烷和3,3`,5,5`-四甲基双(4-氰酰基苯基)甲烷;2,2-双(3,5-二氯-4-氰酰基苯基)丙烷;2,2-双(3,5-二溴-4-二氰酰基苯基)丙烷;双(4-氰酰基苯基)醚;双(4-氰酰基苯基)硫醚;2,2-双(4-氰酰基苯基)丙烷;三(4-氰酰基苯基)亚磷酸酯;三(4-氰酰基苯基)磷酸酯;双(3-氯-4-氰酰基苯基)甲烷;氰化可溶可熔酚醛树脂;1,3-双[4-氰酰基苯基-1-(甲基亚乙基)]苯和氰化双酚封端的聚碳酸酯或其他热塑性低聚物。

此处使用的尤其理想的氰酸酯以商品名“AROCY”商购于HuntsmanSpecialty Chemicals,Brewster,New York或者以商品名“PRIMASET”商购于Lonza Group,Great Britain[1,1-二(4-氰酰基苯基烷烃)]。四种理想的“AROCY”氰酸酯的结构是:
另外,
具有马来酰亚胺、衣康酰亚胺或桥亚甲基四氢邻苯二甲酰亚胺官能度的化合物包括例如在美国专利No.6916856和美国专利申请公布No.2004/00077998中公开的那些,其中每一篇的公开内容在此通过参考引入。
一般地,为了容易处理和加工,热固性树脂组合物的粘度应当在约10-约12,000厘泊(cps)范围内,优选约10-约2000cps。本发明的苯并噁嗪化合物典型地在小于或等于50℃的温度下为液体形式。更具体地,在室温下为液体形式的这种苯并噁嗪在室温下的粘度小于10,000cps,例如在室温下小于150cps。
由于它们具有可流动的粘度,因此本发明的这些含苯并噁嗪的物质组合物不要求外加的稀释剂,或者当与其一起使用稀释剂时,使用与常规的含苯并噁嗪的热固性树脂体系必须添加的量相比远远较低量的稀释剂,以加速处理。
可将稀释剂加入到本发明的物质组合物中,最终希望降低其粘度。可使用任何稀释剂(不管对苯并噁嗪呈惰性还是具有反应性)。代表性的惰性稀释剂包括二甲基甲酰胺、二甲基乙酰胺、N-甲基吡咯烷酮、甲苯、二甲苯、二氯甲烷、四氢呋喃、甲基乙基酮、乙二醇的单烷基或二烷基醚,聚乙二醇、丙二醇或聚丙二醇、二元醇醚和类似物。代表性反应性稀释剂包括单官能和多官能醇的丙烯酸酯和甲基丙烯酸酯,此处更加详细地描述的乙烯基化合物,烯丙基酰胺,富马酸酯,马来酸酯,苯乙烯类单体(即由乙烯基苄基氯与单-、二-或三官能的羟基化合物反应衍生的醚)、降冰片基化合物和类似物。
本发明的物质组合物可包括填料,例如无机填料,例如二氧化硅。其他无机填料包括氮化硅、氮化硼和以下所述的金属填料。
填料可以是传导填料或非传导填料。
填料当为传填料导时,可以是金属填料,例如银、铜、焊料颗粒、氧化铝、氮化铝或三水合氧化铝。
填料当为非传导填料时,可以选自(甲基)丙烯酸类颗粒,例如聚(甲基丙烯酸甲酯)类,PDMS颗粒,聚烯烃颗粒,苯乙烯颗粒,特氟隆和玻璃。
可配制本发明的物质组合物,以便当固化时,在50wt%的填料水平下,它们的热膨胀系数范围为15-35。另外,可配制本发明的组合物,以便当暴露于175℃的温度下2小时的时间段固化时,通过线性测量显示出小于0.1%的体积收缩率。
为了辅助降低本发明组合物发生固化时的温度或者加速在该固化温度下的固化速度,可将催化剂加入到本发明的组合物中。例如,可包括阳离子催化剂、酸催化剂或碱(basis)催化剂。酸催化剂可以是路易斯酸的变体或者可以是羧酸,例如杂环二羧酸。关于这一点,在美国专利No.6376080(Gallo)中公开且要求保护的那些杂环二羧酸尤其可用于催化含苯并噁嗪的组合物,例如各自以商品名IRGACOR 252LD和252FC获自Ciba Specialty Chemicals的2-(2-苯并噻唑基)-琥珀酸和(2-苯并噻唑基硫代)-丁二羧酸的固化。
本发明的物质组合物可用于配制成拟作为底层填料(underfill)、包封剂、模塑料或模片固定(die attach)的组合物。

实施例1
可如下所述制备本发明的液体形式的苯并噁嗪:
将苯胺(93g,1.0mol)、对甲醛(60.0g,2.0mol)、苯酚(94.0g,1.0mol)和甲苯(2000ml)放置在配有机械搅拌器的5000ml三颈圆底烧瓶内。使用具有冷凝器的Dean Stark湿气接收肼,收集由这一反应生成的水。加热这一混合物,回流4小时的时间段,同时继续搅拌。收集总量为36ml(2.0mol)的水。允许反应混合物冷却到室温并流经硅胶薄层。然后通过旋转蒸发,除去溶剂,并用氮气吹扫残留液体4小时的时间段。以浅红色液体形式获得最终产物(苯并噁嗪#4),产率为96%。
实施例2
在混合的情况下,添加苯并噁嗪到氰酸酯和二氧化硅中,制备在本发明范围内的物质组合物,得到在室温下粘度为8000cps的体系,在90℃的温度下其粘度下降到200cPs,且可在175℃的温度下固化2小时的时间段。由45.5%苯并噁嗪#4,4.5%氰酸酯(L-10)和50.0%二氧化硅(FL-1950),制备这一组合物,其中每一种均以重量为基础。
在试样上在175℃的温度下固化4小时的时间段之后,观察新固化的样品,Tg为135℃(通过热机械分析测量),CTE为23.6ppm,室温模量为6.9Gpas(在高于180℃的温度下降低到约20MPas),固化之后的收缩率为0.07%,且坚固地粘合,如下表1所示。
使用陶瓷基底和300mil的模头,在组合物置于模头和基底之间的情况下,制备组件。这一组件在175的温度下分别固化2小时和4小时的时间段。然后将组装的部件放置在用水覆盖的压力容器内,然后将该压力容器置于维持在121的温度下的烘箱内96小时的时间段。下表1中列出的结果显示出低于Tg(135℃)时坚固的粘合。
表1
大于100Kg的数值表明该力超过进行评价所使用的模头剪切机可评价的最大值。
因此,表1所示的模头剪切评价表明非常良好的性能连同低的吸湿率数值。
在收缩率评价中,实施例2的组合物在钢模内在175的温度下固化2小时的时间段。实施例2的组合物显示出0.07%的收缩率值。这一低程度的收缩率也是非常有前景的物理性能。
实施例3
在这一实施例中,结合苯并噁嗪#18与1wt%含量的二羧酸催化剂IRGACOR LD252,得到样品A。由样品A制备两个额外的样品-样品B和C,但分别填充有50%和60%二氧化硅。一旦在165的温度下固化4小时的时间段,观察到样品A、B和C的CTE值分别为48、25和22。
实施例4
在这一实施例中,结合苯并噁嗪#12与1wt%含量的IRGACORLD252,得到样品D。一旦在165℃的温度下固化4小时的时间段,观察到样品D的CTE值为47。
另外,在有和无氰酸酯AROCY L10或L31和在各种二氧化硅负载水平下,将苯并噁嗪#12用作CTE评价的基础。参考下表2,示出了在175℃的温度下固化4小时的时间段之后观察到的负载水平和CTE值。
表2
