摘要
采用核磁氢谱、碳谱、红外图谱、质谱等手段对市场上现有的几种耐根穿刺防水卷材用化学阻根剂进行定性分析,得出其都含有2-(4-氯-2-甲基苯氧基)丙酸酯基结构单元。研究了不同种类化学阻根剂的稳定性以及不同工艺对其分散有效性和耐老化性的影响,指出加入顺序、温度等工艺都会影响阻根剂的有效保留量,需根据实际情况选择和调整。
Some chemical root resistant agents available on market used in root resistant waterproofing membranes is qualitative analyzed by various means such as nuclear magnatic hyrongen spectum,crabon spectrum,infrared spectrum and mass spectrum.The result shows that all agents studied have structure unit of propionate group.The stability of various root resistant agents and influence of technologies on dispersive effctiveness and aging resistance are studied,showing adding sequence and temperature of the agent affects effective quantity of the agent.
