摘　　要：马来酸酐和甘油在1∶1的比例下进行反应,得到中间产物马来酸单甘油酯。中间产物分别与乙酸钙/锌反应,得最终产物马来酸单甘油钙/锌。通过傅立叶红外测试分析了产物的结构。通过刚果红法、热老化法、热失重法、电导率来检测,讨论了其热稳定性能,并和硬脂酸钙/锌进行了对比。通过制酸能力测试,分析了热稳定机理,同时讨论了与β-二酮(硬脂酰苯甲酰甲烷)的协同作用。结果表明,当马来酸单甘油酯钙/锌中的钙、锌比例为2∶1时,有较好的协同作用,初期白度可以达到40 min,静态稳定时间为34 min;与β-二酮复配热稳定性能有明显提升,可以有效地延长热稳定的时间,维持初期白度达50 min,直到80 min仍未黑化。Maleic anhydride and glycerol reacted at a ratio of 1∶1 to get an intermediate product:monoglyceride maleate.Then the monoglyceride maleate reacted with calcium/zinc acetate led to the final product:calcium/zinc monoglyceride maleate.The structure was analyzed by Fourier infrared.The thermal stability was discussed by the congo red method,heat aging method,thermogravimetric method and conductivity test,and compared with calcium stearate/zinc.The mechanism of thermal stabilization was analyzed by the acid production test,and discussed the synergy withβ-diketone(stearoylbenzoylmethane).The results showed that when the calcium/zinc monoglyceride maleate ratio was 2∶1,there was a good synergistic effect,the initial whiteness could remain reach 40 min,and the static stabilization time was 34 min;the thermal stability of addingβ-diketone is significantly improved.The initial whiteness could reach 50 min,and not turned black until 80 min.
