摘　　要：利用环氧化橡胶籽油(ERSO)与甲基丙烯酸羟乙酯化马来酸半酯(HEMAMA)发生开环反应,制备了新型的橡胶籽油基类环氧丙烯酸酯(HMMERSO)预聚体,采用FT-IR和1H NMR确认其化学结构,研究了HMMERSO与不同稀释剂混合所得光固化材料的最终性能。研究结果显示:所得HMMERSO中每一个甘油三酯分子具有4.85个CC官能团,含生物基71.2%。HMMERSO材料展示了优良的性能,纯HMMERSO材料在常温下储能模量能达752.8 MPa,玻璃化转变温度(Tg)为67.4℃,拉伸强度和模量分别为9.84和365.5 MPa,其值分别是纯环氧大豆油丙烯酸酯(AESO)材料值的7.7倍、4倍、5.1倍和9.7倍。用30%甲基丙烯酸羟乙酯稀释剂改性后材料的性能更佳,其拉伸强度达到26.1 MPa,Tg达到90.9℃。Epoxidized rubber seed oil(ERSO)and hydroxyethyl methacrylate maleate(HEMAMA)precursors underwent epoxide-opening reaction to prepare a new rubber seed oil-based epoxy acrylate(HMMERSO).Polymer and its chemical structure were confirmed by FT-IR and 1H NMR.The final properties of the photocurable materials obtained by mixing HMMERSO with different diluents were also studied.The obtained HMMERSO had 4.85 CC functional groups in per triglyceride molecule,and the bio-based content was 71.2%.The HMMERSO material was found to exhibit excellent performance.The storage modulus of HMMERSO material at normal temperature could reach 752.8 MPa,the glass transition temperature(Tg)was 67.4℃and the tensile strength and modulus were 9.84 and 365.5 MPa,which were 7.7,4,5.1 and 9.7 times of the values of the epoxidized soybean oil acrylate(AESO)material,respectively.The performance of the material modified with 30%hydroxyethyl methacrylate diluent was better,and its tensile strength reached 26.1 MPa and Tg reached 90.9℃.
