有机硅改性环氧树脂的研究进展与展望

Research progress and prospect of silicone modified EP

以有机硅改性环氧树脂,不仅使树脂具有优良的韧性、耐氧化性和热稳定性等性能,而且还会产生较好的经济效益,在众多领域表现出广阔的应用前景和巨大的开发价值。从物理共混改性和化学共聚改性两个方面介绍了有机硅改性环氧树脂的研究现状及改性机理;在此基础上对有机硅改性环氧树脂在裂纹修补领域的发展趋势进行了展望。

The modification of epoxy resin(EP)with silicone not only makes the resin have excellent toughness,oxidation resistance and thermal stability,but also produces better economic benefits,showing broad application prospects and great development value in many fields.The research status and modification mechanism of silicone modified EP were introduced from two aspects:physical blending and chemical copolymerization modification.
