摘　　要：针对化学阻根类耐根穿刺防水卷材中是否含有阻根剂以及阻根剂含量的检测,提出一种简易的沉淀滴定方法,介绍了该方法的试验步骤以及数据处理。结果表明,沉淀滴定法可以辅助判定防水卷材中是否含有阻根剂,其测得的阻根剂数值与理论值相比偏低,但偏差在可接受范围内,可用于企业生产制造过程中的品质管控。A simple precipitation titration method is proposed to detect the presence and content of root blocking agent in chemical root resistant waterproofing membranes,and the test procedures and data processing of this method are introduced as well.The results indicate that the precipitation titration method can assist in determining whether there is root blocking agent in waterproofing membranes.The measured value of the root blocking agent is relatively lower than the theoretical value,but the deviation is within an acceptable range,which can be used for quality control in the production process of enterprises.
