Description
技术领域
本发明涉及电子元器件领域,具体涉及一种阻燃型环氧树脂及其制备方法。
背景技术
环氧树脂是指分子中含有两个以上环氧基团的一类聚合物的总称。它是环氧氯丙烷与双酚A或多元醇的缩聚产物。由于环氧基的化学活性,可用多种含有活泼氢的化合物使其开环,固化交联生成网状结构,因此它是一种热固性树脂。环氧树脂以其绝缘性能高、结构强度大和密封性能好、成本低廉的优点被广泛应用于电子元器件领域。
由于普通环氧树脂材料制成的电子器件在高温时会分解发烟并伴有明火的缺点,限制了环氧树脂的应用,存在很大的安全隐患。

进一步的,所述的纳米无机填料为纳米二氧化硅。
进一步的,所述的固化剂为异佛尔酮二胺,促进剂为水杨酸和苯甲醇的混合物。水杨酸与苯甲醇的比例为1:7时固化效果最佳,通过水杨酸和苯甲醇的协同作用,即使在室温条件下,也可实现均匀快速的固化。
进一步的,所述的阻燃剂为季戊四醇磷酸酯的三聚氰胺盐。
一种根据权利要求1所述的阻燃型环氧树脂的制备方法,其特征在于:包括以下步骤:
1)将二酚基丙烷型环氧树脂60~80份,邻苯二甲腈树脂2~10份,纳米无机填料200~240份,在反应釜中搅拌混合,在80~120℃温度下反应4-8H;
2)将固化剂5~10份,促进剂0.5~2份,阻燃剂1~10份,加入步骤1)反应后的溶液中,室温下混合均匀,得到阻燃型环氧树脂。
进一步的,步骤2)中反应的时间为6-8H。
进一步的,所述的环氧树脂的环氧值≥0.8。
与现有技术相比,本发明的的有益效果为:本发明提供的阻燃型环氧树脂,各组分之间相互配伍产生协同作用,本发明采用纳米二氧化硅,通过与环氧树脂的协同作用,使制成的环氧树脂强度硬度提高,抗老化性增加;
本发明采用的固定剂为异佛尔酮二胺,促进剂为水杨酸和苯甲醇的混合物。通过水杨酸和苯甲醇的协同作用,即使在室温条件下,也可实现均匀快速的固化
本发明制得的阻燃型环氧树脂的阻燃型耐热性满足400~500℃无明火,可被用于电阻元件的封装,且本发明制得的阻燃型环氧树脂有良好的强度硬度、抗老化性及耐湿性能,特别适合用于制作浴室电器元件。
