【摘要】 以氨三乙酸和氧化锌为原料,制备了氨三乙酸锌,并对其进行了红外光谱分析及物化常数检测;以甘氨酸锌、硬脂酸锌作对照物,将氨三乙酸锌与氨三乙酸钙、硬脂酸钙、亚磷酸三苯酯进行了互配,通过热老化箱实验法、刚果红试纸法等对氨三乙酸锌及其互配体系进行了综合评价。结果表明,氨三乙酸锌对PVC具有较好的长期热稳定性能,与硬脂酸钙具有较好的协同作用。更多还原

【Abstract】 Zinc nitrilotiracetate was prepared through the reaction of nitrilotiracetic acid and zinc oxide, which was employed as a stabilizer of PVC. When it was introduced into PVC together with calcium nitrilotiracetate and calcium stearate, a synergic effect was observed, which imparted PVC a long-term stability. Compared with zinc glycin and zinc stearate, zinc nitrilotiracetate achieved a better result in thermal stability.更多还原
