本发明提供了一种含磷活性酯及其无卤树脂组合物以及使用它的预浸料和层压板。该无卤树脂组合物包括:(A)热固性树脂;(B)含磷活性酯树脂。使用这种无卤树脂组合物制成的预浸料和层压板,具有低介电损耗因子并且能实现无卤阻燃。
Description
本发明属于覆铜板技术领域,具体涉及一种含磷活性酯及其无卤树脂组合物以及使用它的预浸料、层压板和印制电路板。
随着电子元器件朝着小型轻量薄型化、高性能化、多功能化的方向发展,随之带来的是高频、高速的信号传输。这就要求电子材料的介电常数和介电损耗比较低,这些与材料的结构有关,而低介电常数、低介电损耗树脂在结构上一般具有:大的自由体积、低的可极化、低吸水率、低介电常数的结构存在等特点。此外,2006年7月1日,欧盟的两份环保指令《关于报废电气电子设备指令》和《关于在电气电子设备中限制使用某些有害物质指令》正式实施,无卤阻燃覆铜箔层压板的开发成为业界的热点,各覆铜箔层压板厂家都纷纷推出自己的无卤阻燃覆铜箔层压板。
在覆铜板的树脂基体中引入含磷化合物,成为覆铜板无卤阻燃的主要技术路线。目前覆铜板领域上广泛采用的磷系阻燃剂主要分为反应型与添加型两种。反应型主要为DOPO类化合物,以含磷环氧树脂、含磷酚醛树脂为主,磷含量在2~10%之间。然而,实际应用中发现,DOPO类化合物具有较大的吸水率和较差的介电性能及板材耐湿热性差。添加型主要为磷腈和膦酸酯类化合物,添加型阻燃剂的阻燃效率较低,需要添加更多的量才能达到阻燃要求。同时因其较低的熔点(一般低于150℃),在层压板加工过程中,易迁移至板材表面,影响板材性能。

(1)玻璃化转变温度(Tg):根据差示扫描量热法(DSC),按照IPC-TM-6502.4.25所规定的DSC方法进行测定。
(2)介电常数和介电损耗因子:按照IPC-TM-650 2.5.5.9所规定的方法进行测试,测试频率为10GHz。
(3)阻燃性:按照UL 94标准方法进行。
物性分析:
由表1~2中实施例1~9可知,引入含磷活性酯固化剂后,体系均具有较低的介电损耗因子并且能够满足UL94V-0级阻燃要求;由实施例7可知,在引入二氧化硅填料后,体系具有更低的介电损耗因子;由实施例8和实施例9可以看出,由于引入自由体积大且对称的环状DOPO结构,使三元体系具有更低的介电损耗因子及更高的玻璃化转变温度。
由表2的对比例1和对比例2可知,引入双环戊二烯型活性固化剂后,体
系具有较低的介电损耗因子,但不能满足UL94的阻燃要求,而且即使加入阻燃剂后虽然可满足UL94阻燃要求,但介电损耗因子略有增加;而从实施例3~6可知,相对于对比例1和对比例2,其在满足UL94V-0级阻燃要求的同时,由于引入自由体积大且对称的环状DOPO结构,体系具有更低的介电损耗因子及具有更高的玻璃化转变温度。
由表2的对比例3与实施例7相比,以及对比例5与实施例8相比可知,由DOPO结构阻燃剂和双环戊二烯型活性酯混合替代本发明的含磷活性酯固化剂,体系耐热性及介电性能差;由对比例4可知,引入氰酸酯可以降低体系的介电损耗因子,但仍无法满足UL94V-0级阻燃要求;由对比例5和对比例6可知,引入阻燃剂可以改善阻燃性能,但介电损耗因子有所增加,即使通过添加填料后降低体系的介电损耗因子但仍高于实施例8和实施例9体系的介电损耗因子。
如上所述,与一般的层压板相比,本发明的无卤组合物制成的电路基板材料具有低介电损耗因子并且能够实现无卤阻燃。
以上所述,仅为本发明的较佳实施例,对于本领域的普通技术人员来说,可以根据本发明的技术方案和技术构思做出其他各种相应的改变和变形,而所有这些改变和变形都应属于本发明权利要求的范围。
