摘要
以脂环族环氧树脂为基体树脂,以氮化铝(AlN)为导热填料,制备了用于光显示基板的UV胶粘剂。通过测试显示基板上UV胶与铜箔间的综合性能(包括导热性能、剥离强度、耐浸焊性、可靠性分析及透光率测试)对材料进行全面评价。研究结果表明:在m(TA3150)∶m(TA21)=40∶60、光引发剂用量为环氧树脂质量分数3.5%、光促进剂用量为环氧树脂质量分数6%的胶液中,AlN用量为环氧树脂质量60%,UV胶可快速固化。其导热系数为1.1 W(/m·K),剥离强度为1.20 N/mm,耐浸焊时间达到10 min,透光率为86%,有很好的可靠性,满足LED玻璃光显示基板制备的性能要求,具有广阔的应用前景。
UV adhesive for light display substrate was prepared by using alicyclic epoxy resin as matrix resin and aluminum nitride(AlN)as thermal conductive filler.The material was overall evaluated by testing the comprehensive performance between the UV adhesive on the substrate and the copper foil,including thermal conductivity,peel strength,immersion welding resistance,reliability analysis and light transmittance test.The research results showed that,in the adhesive solution with m(TA3150)∶m(TA21)=40∶60,the content of photoinitiator was 3.5%of epoxy resin mass fraction,the content of photopromoter was 6%of epoxy resin mass fraction,the content of AlN was 60%of epoxy resin mass fraction,the UV adhesive could be quickly cured.Its thermal conductivity was 1.1 W(/m·K),peel strength was 1.20 N/mm,immersion welding resistance time reached 10 minutes,and light transmittance was 86%.It had good reliability and met the performance requirements of LED glass display substrate preparation,which had broad application prospects.
