| 摘 要： | 采用溶液聚合法合成了以丙烯酸丁酯为主链的液态含环氧基丙烯酸酯低聚物,并用其对环氧树脂进行增韧改性.讨论甲基丙烯酸环氧丙酯以及低聚物用量对改性环氧树脂力学性能的影响,并研究了改性环氧树脂的微观形态和耐热性能.结果表明:当低聚物用量为10%(质量分数),丙烯酸丁酯和甲基丙烯酸环氧丙酯的质量比为80∶20时,改性环氧树脂的拉伸强度和冲击强度比纯环氧树脂提高6.7%和219.1%,同时体系的耐热性能基本不下降;改性环氧树脂呈两相结构,随低聚物用量增加橡胶粒子粒径尺寸增大;且Tg先升高后降低. |

| Abstract: | Liquid acrylate oligomers containing epoxy groups were synthesized by solution polymerization,and used to modify epoxy resin.The influence of epoxypropyl methacrylate(GMA) and oligomer content on the mechanical properties of modified systems was discussed.The morphology and thermodynamics properties of modified epoxy resins were studied.The results showed that the tensile strength was improved about 6.7% and impact strength was improved about 219.1%,and the property of heat resistant was remained,when mass ratio of BA/GMA was 80/20 and the mass fraction of oligomer was about 10%.The modified epoxy resins had two-phase morphology.With the increased of the oligomer content,the sizes of rubber particles increased,and Tg rised at first and then droped. |
