Abstract:
This research adopted four methods to toughen epoxy adhesives. They were liquid hydroxyl group terminated polybutadiene(HTPB)rubber modification, silicon rubber modification, polyacrylate multiplicity elastomer particulates emulsion modification and chemical grafting modification. After modification, the shearing strength and the rupture elongation were tested. The interface and the chemical reaction between the modifiers and the epoxy were analyzed by scanning electron microscope(SEM)and infrared optical spectrum. The results show that the elastomer particulates modification and the chemical grafting modification can reach the better toughening effects.
采用了4种方法增韧环氧树脂胶粘剂, 分别是端羟基聚丁二烯液体橡胶改性、硅橡胶改性、聚丙烯酸酯复合弹性体微粒乳液改性及化学接枝共聚改性.研究过程中测试了剪切强度和断裂伸长率, 并分别运用了扫描电镜图和红外光谱图分析了界面特性及改性剂与环氧树脂间的化学反应.研究结果表明, 复合弹性体微粒改性和化学接枝改性能够取得更好的效果.
