摘要：以火麻仁油(HO)为原料,制备合成了一种新型的含羧基和乙烯基的火麻仁油基可双重交联树脂基单体(MA-AEHO),并采用傅里叶变换红外光谱(FT-IR)和核磁共振氢谱(~1H NMR)对单体结构进行了表征。将MA-AEHO通过不同的交联聚合工艺,制备得到了2种单交联聚合物(1和2)及2种双重交联聚合物(3和4),并对4种聚合物的性能进行对比测试。机械性能测试表明:聚合物1~4的拉伸强度分别为9.21、14.73、32.05和33.25MPa,断裂伸长率分别为56.21%、9.97%、4.56%和3.18%,相比于单交联体系而言,双重交联体系的聚合物(3和4)的拉伸强度均显著提高,断裂伸长率有所下降;动态热机械分析表明:相比于单交联聚合物,双重交联聚合物(3和4)具有高储能模量(32.00和41.29MPa)和玻璃化转变温度(58.08和91.44℃)。热重分析结果表明:4种交联聚合物均具有良好的热稳定性,材料的初始热分解温度均在300℃以上。
A novel type of dual-crosslinking resin monomer(MA-AEHO) containing carboxyls and vinyls was synthesized using hemp oil(HO) as raw material.The monomer structure was characterized by FT-IR and ~1H NMR. Two single-crosslinking polymers(polymer 1 and 2) and two dual-crosslinking polymers(polymer 3 and 4) were obtained by the polymerization of MA-AEHO with the different curing and cross-linking processes. The properties of four polymers were tested.Mechanical performance tests showed that the tensile strength of polymer 1-4 is 9.21, 14.73, 32.05 and 33.25 MPa, and the elongation at break is 56.21%, 9.97%, 4.56% and 3.18%, respectively. Their tensile strengths were significantly improved and the elongations at break were decreased compared with the single-crosslinking polymers. Dynamic thermal mechanical analysis showed that the dual-crosslinking polymers(polymer 3 and 4) have relatively higher energy storage modulus(32.00 and 41.29 MPa) and glass transition temperature(58.08 and 91.44 ℃) than those of the single-crosslinking polymers. Thermogravimetric analysis results showed that these four curing polymers possessed good thermal stability, and the initial decomposition temperature of the polymers are all above 300 ℃.
