聚氨酯建筑密封胶拉伸模量与环境温度关系的研究

Study on Relationship between Stretch Modulus of Polyurethane Building Sealant and Ambient Temperature

选取两款低模量聚氨酯建筑密封胶为研究对象,研究了聚氨酯建筑密封胶拉伸模量与环境温度之间的关系,并借助Origin数据分析软件对二者之间的关系进行拟合分析。结果表明,聚氨酯密封胶拉伸模量随使用环境温度的下降而增大,二者之间满足指数函数关系,同时给出了相应的指数函数方程式。

The article chose two low-modulus polyurethane building sealants as research objects. It studied the relationship between the sealants＂ stretch modulus and ambient temperature, and it had fitting analysis of the relationship with the help of Origin ——a data analysis software. The results showed the stretch modulus of polyurethane sealant was increasing with the decrease of ambient temperature, the relationship between them conformed to exponential function relationship, and the paper also offered corresponding exponential function equation.
