摘要
耐热性是聚氨酯弹性体的一项重要性能指标。微相分离结构对聚氨酯弹性体的耐热性能有很大的影响。主要介绍了聚氨酯弹性体微相分离结构及其他因素对其耐热性的影响。介绍了聚氨酯弹性体耐热性的改性方法。提高微相分离程度是改善其耐热性的重要方法之一。
The heat resistance is an important performance of polyurethane elastomers.The microphase separation structure has a great influence on the heat resistance of polyurethane elastomers.This paper mainly introduced the effects of the microphase separation structure and other factors on the heat resistance of the elastomers,and the improving methods of their heat resistance.Increasing the degree of microphase separation may be an effective method of improving the heat resistance of the elastomers.
