Description

一种半固化环氧胶膜及其制备方法
技术领域
本发明涉及一种半固化环氧胶膜及其制备方法,属于高分子技术领域。
背景技术
环氧胶黏剂作为一种综合性能优越的工业产品,目前在诸多领域都有着广泛的应用,其中环氧胶膜作为其中一种比较特殊的形式近年来也受到越来越多的重视。环氧胶膜主要应用于电子、微电子行业的中小型电子元器件的真空封装、导电、粘接固定等。
常用的环氧胶膜采用固体或固体和液体树脂混合的形式作为主材料,添加有一定的潜伏性固化剂、填料、助剂等,常温状态下为不粘手的无弹性薄膜状,应用时采用加温加压的方式,使其具有一定的粘性、流动性,在充分润湿基材的情况下,再进行固化。
目前,市场上出现一种对于环氧胶膜新的需求,即环氧胶膜作为器件两个部分的中间粘接固定部分应用时,需要在常温下具有一定的粘性和弹性,具有保持形状能力、稳定性好的特点,应用时直接贴附于器件的一个组件之上,另一个组件自然压在其上并进行后固化即可,且固化后性能要求高,需要有较高的粘接强度和较低的线膨胀系数,以适应器件的耐久性测试。这种要求与市场上现有的环氧胶膜的特性有一定的偏差,开发难度大,应用前景广阔。
发明内容
针对现有技术的不足,本发明要解决的技术问题是提供一种半固化环氧胶膜及其制备方法,该材料具有常温下具有一定粘弹性、固化后性能优越等特点,可用于电子、微电子行业的小型器件的粘接固定。

优选地,所述的环氧树脂为双酚A型环氧树脂、双酚F型环氧树脂、脂环族环氧树脂、溴化环氧树脂、含萘环氧树脂、双环戊二烯型环氧树脂、柔韧性嵌段环氧树脂、酚醛环氧树脂、二聚酸改性环氧树脂中的一种或几种。
优选地,所述的活性稀释剂为正丁基缩水甘油醚、C12~C14烷基缩水甘油醚、苯基缩水甘油醚、聚丙二醇二缩水甘油醚中的一种或几种。
优选地,所述的固化剂包含潜伏性固化剂和常温固化剂,其中潜伏性固化剂为双氰胺、咪唑类、胺类、脲类、酰肼类、酚醛树脂类中的一种或几种,常温固化剂为聚醚胺、聚酰胺、脂肪胺、脂环胺中一种或几种。
优选地,所述的颜料是色膏,色膏为炭黑复合物;填料为硅微粉、氢氧化铝粉、核/壳橡胶粒子、碳酸钙中的一种或几种。
优选地,所述的助剂包含有消泡剂、偶联剂、分散剂等。消泡剂
为毕克化学的BYK-A530,BYK-A555,BYK-066N,BYK-141,BYK-1770中的一种或几种。偶联剂为带环氧基的硅烷偶联剂、γ-缩水甘油醚氧丙基三甲氧基硅烷、β-(3,4-环氧环己基)乙基三甲氧基硅烷的一种或几种。分散剂为毕克化学的BYK-W9010、BYK-W9011中的一种或几种。

优选地,所述的助剂用量为对应每100份环氧树脂使用0.2-1份。
与现有的技术相比,本发明的有益效果在于:
通过使用常规树脂、功能树脂复合并调整不同类型的树脂的比例,选用不同固化温度的固化剂并调整其比例,来控制半固化胶膜的固化程度和完全固化后的各项性能,最终得到了半固化阶段粘弹性合适且储存稳定性好、完全固化阶段性能优良的产品,可以同时满足在器件上应用的合适工艺性和最终作为粘接固定材料的优秀的物理性能和耐老化性能。
该环氧胶膜的粘手度好,第一法向应力差(80℃)在0.5MPa以上,完全固化后的产物玻璃化转变温度可达100℃以上,线膨胀系数低于50ppm/℃,剪切粘接强度(Al-Al)可达20MPa以上。
具体实施方式
下面通过具体实施方式来进一步说明本发明的技术方案。
如无具体说明,本发明的各种原料均可市售购得,或根据本领域的常规方法制备得到。
本实施例提供的一种半固化环氧胶膜的制备方法,包括如下步骤:
按重量份计,取混合树脂、活性稀释剂、颜料、助剂加入到反应釜中并高速搅拌混合均匀;
按重量份计,在之前步骤得到的混合料中缓慢加入填料,抽真空的情况下高速搅拌混合均匀;
按重量份计,在之前步骤得到的混合料中缓慢加入潜伏性固化剂,控制温度≤40℃以及抽真空的条件下高速搅拌混合均匀;
按重量份计,在之前步骤得到的混合料中加入常温固化剂,控制温度≤40℃以及抽真空的条件下高速搅拌混合均匀,得到所需的环氧胶膜用液体料;
将以上液体料通过涂布机辊涂,后经80℃/60min的预固化得到环氧胶膜。
以下实施例的半固化环氧胶膜均采用上述的制备方法得到。

将实施例1-4和对比例1-3所制得的半固化环氧胶膜及其完全固化后的最终产物进行对比测试,实验结果如下:
Figure BDA0002566209740000062
由以上测试结果可以得知,两种不同固化温度的固化剂分别对半固化胶膜和完全固化后的性能有重要影响,在配合相应树脂的情况下,常温固化剂的用量在合理范围内可以提供良好的粘弹性,第一法向应力差可达到0.5MPa以上,低于范围则不具备较好的应用效果。潜伏性固化剂的用量可以对完全固化后的性能有很大改变,两种固化剂搭配得当,Tg可达到100℃以上,剪切粘接强度(Al-Al)高于20MPa。
填料的用量可以决定整个体系完全固化后的CTE(线膨胀系数),其用量越多,则CTE越低,本发明的最终固化物CTE可低于50ppm/℃,但鉴于填料用量的增加对于混合难度也显著增大,因此需要控制在一定合理的范围内。
以上借助具体实施例对本发明做了进一步描述,但是应该理解的是,这里具体的描述,不应理解为对本发明的实质和范围的限定,本领域内的普通技术人员在阅读本说明书后对上述实施例做出的各种修改,都属于本发明所保护的范围。
