Description
技术领域
本发明涉及一种含磷环氧树脂组合物及应用其制备的半固化片和层压板,属于电子材料技术领域。
背景技术
现有技术中,传统溴化阻燃剂如溴化环氧树脂、四溴双酚A等,阻燃性优异,且价格相对低廉,一直以来是普通FR-4覆铜板的主要阻燃剂。但是,随着人们生活质量和安全意识的提高,人们对身边电子产品的安全性要求越来越高。含溴阻燃剂在燃烧过程中产生二噁英、多溴二苯并呋喃等刺激性、腐蚀性的有毒气体溴化氢,危害人们的健康并造成污染。此外,由于含溴阻燃剂中的碳溴键的键能较弱,导致其热分解温度较低,在高性能覆铜板应用中存在明显不足。
目前,阻燃剂的发展方向日益趋于无卤化,各国阻燃材料制造商开始以严谨的态度对待溴化阻燃剂在高聚物中的应用,无卤阻燃剂,特别是磷系阻燃剂逐渐成为主流。其中以DOPO(9,10-Dihydro-9-oxa-10-phosphaphanthrene-10-oxide)最为重要,在印刷电路板走入高频化后,可以获得良好的阻燃性能和介电性能。但是,由于DOPO环在高温高湿或碱性条件下吸水率较高,影响电路板的介电性能及耐湿热性能。
另一方面,现有技术中的添加型阻燃剂都是物理共混于树脂体系中,无法与树脂发生反应,从而会导致树脂体系的吸水率较高、耐热性差。
鉴于上述问题,开发一种无卤阻燃并且兼具高耐湿热、低吸水率、高阻燃性、剥离强度高以及介电性能好的含磷环氧树脂组合物、以及使用其制作的半固化片及层压板,显然具有积极的现实意义。

由于上述技术方案运用,本发明与现有技术相比具有下列优点:

2.本发明的环氧树脂组合物中因为磷化合物改性环氧树脂中的磷化合物的结构中引入了异氰酸酯基,可以一定程度上提升改性环氧树脂的剥离强度;
3.本发明的环氧树脂组合物中因为磷化合物改性环氧树脂中的磷化合物中含有硅氧键,在环氧树脂固化过程中,可以形成硅氧键网状结构,从而限制了整个环氧树脂固化物的移动,从而一定程度上提升了改性环氧树脂的Tg;从而提高了体系的耐热性能;
4.实验表明,本发明的含磷环氧树脂组合物具有无卤阻燃、高耐湿热、低吸水率、高阻燃性、剥离强度高以及介电性能良好的特点;使用该树脂组合物制备的半固化片及层压板,其同时具有无卤阻燃、高耐湿热、低吸水率、高阻燃性、剥离强度高以及介电性能良好的特点,可以作为电子仪器用印制线路板。

表1采用不同实施例所得的层压板性能
注:表中相关测试数据是基于RC=50%的层压板样品。
表中特性的测试方法如下:
(1)耐燃烧性(阻燃性):依据UL94法测定。
(2)吸水率(%):按照IPC-TM-650 2.6.2.1所规定的方法测试A态吸水率。
(3)介电常数:按照IPC-TM-650 2.5.5.9使用平板法,测定1GHz下的介电常数。
(4)介电损耗角正切:按照IPC-TM-650 2.5.5.9使用平板法,测定1GHz下的介电损耗因子。
(5)玻璃化转变温度(Tg,℃):根据差示扫描量热(DSC)法,按照IPC-TM-6502.4.25所规定的DSC方法进行测定。
(6)剥离强度(PS,N/mm):按照IPC-TM-650 2.4.8方法中的“热应力后”实验条件,测试金属盖层的剥离强度。
(7)湿热处理后浸锡耐热性:取3块10cm×10cm、厚度为0.80mm、两面去除金属箔的样品,在100℃干燥2小时,然后用高压锅蒸煮试验(Pressure Cooker test)机,在121℃、2个大气压下处理1小时后,在288℃的锡炉中浸锡20s,目测观察是否有分层现象。3块中如有0,1,2,3块分层现象分别记为0/3,1/3,2/3,3/3。
