摘　　要：研究了TPO防水卷材热老化性能的影响因素,结果表明:抗氧剂对TPO防水卷材热老化性能的影响显著;此外,PP、PE的含量、Ca CO3的含量、Mg(OH)2的种类等都对TPO防水卷材的热老化性能有影响,在其生产应用中必须加以重视。The influencing factors of thermal aging properties of TPO waterproofing membrane are studied. The experimental results show that the thermal aging properties of TPO waterproofing membrane are mainly related to antioxidants. In addition, the types of TPO resin, dosage of PP, PE and CaCO3, the type of Mg（OH ）2 also have important effects on the thermal aging properties of TPO waterproofing membrane.
