摘要

通过分析三元乙丙橡胶（EPDM）防水卷材的特点

针对带保护层EPDM防水卷材因受到热、氧作用

会发生一定程度的老化。以力学性能的下降和增塑剂的迁移表现尤为突出

从而造成此种材料的使用寿命的缩减。对老化前后试样进行SEM及FTIR的微观测试

采用加速热老化及热分析动力学的方法

分别建立EPDM防水卷材性能指标、使用条件和使用寿命关系的模型

对其使用寿命进行预测

为建筑设计、施工及材料的研究

提供一定的技术支持。

Abstract

The characteristics of EPDM waterproofing membrane are analyzed. Due to the effect of heat and oxygen

aging occurs to EPDM waterproofing membrane with a protective layer to some extent. And the decline of mechanical properties and plasticizer migration are particularly outstanding

resulted in a reduction in service life of the material. Unaged and aged samples were tested by SEM and FTIR. Furthermore

by using accelerated thermal aging and thermal analysis kinetic method

mode of EPDM waterproofing membrane between performance indicators and service life under certain conditions was established to predict its service life

which provides technical support for architectural design

building construction and material research.
