摘要：选用富含不饱和共轭三键的桐油为原料,通过酯交换和D-A反应,合成了具有六元环结构的三酸三酯类化合物3-正丁基-6-(9-癸烯酸乙酯-10基)-4-环己烯二酸二甲酯(C22-三元酸一乙二甲酯,TM211).采用分子量法测定和红外光谱法确定三酯类化合物的结构,并对PVC进行塑化.研究了塑化后PVC的状态、玻璃化转变温度、拉伸性能、抗萃取性能和热失重性能.结果表明:①桐油乙酯可与马来酸二甲酯合成增塑剂TM211产品;②XRD表明,该产品可有效地破坏PVC结晶性;③DMA表明,TM211较TM188可更有效地降低PVC的Tg;④拉伸试验和扫描电镜均显示,TM211对PVC的增塑性能与DOP相当,且可提高材料的拉伸强度;TM211在水、乙醇、乙醚等5种溶剂中的耐抽出性及挥发性能均优于DOP;⑤热重分析及热解活化能表明,TM211可有效地提升PVC材料的热稳定性;⑥热重-红外-质谱联用分析表明,TM211能使PVC更稳定,原因是其降低了PVC中的HCl含量,使其更容易以氯代烃的形式分解.
The dimethyl compound 3 -n-butyl-6-( ethyl-9 -decenoate-10-yl)-4 -cyclohexene diacid dimethyl ester ( C22-monoethyl dimethyl triacidate, TM211 ) with six-membered ring construction was synthesized from tung oil with abundant conjugated triple bonds by ester exchange and D-A reaction. The structure of tri-esters was characterized by gel permeation chromatography and infrared spectroscopy. The state, glass transition temperature, tensile properties, extraction resistance and thermogravimetric properties of plasticized PVC were studied. The results showed that:(1 ) tung oil ethyl ester could synthesize TM211 plasticizer w让h dimethyl maleate;( 2 ) XRD showed that TM211 could effectively destroy the crystallinity of PVC;(3 ) DMA showed that TM211 could reduce the Tg of PVC more effectively than TM188;( 4 ) tensile tests and scanning electron microscopy showed that the plasticity of TM211 to PVC was similar to that of DOP, and the tensile strength of the material could be increased;The extraction resistance and volatility of TM211 in water, ethanol and ether were better than that of DOP;( 5 ) thermogravimetric analysis and activation energy of pyrolysis showed that TM211 could effectively improve the thermal stability of PVC materials;( 6 ) thermogravimetric-infrared-mass spectrometry analysis shows that TM211 could make PVC more stable, because it reduced the amount of HC1 in PVC and made it easier to decompose in the form of chlorohydrocarbons.
