石油沥青聚氨酯防水材料甲乙组分的相容性研究

石油沥青填充聚氨酯防水材料性能较好 ,价格低廉 ,而能否成功地实现石油沥青对聚氨酯填充的技术关键在于相容剂的选择。本文所建立的“牵线实验”和“表面玷污性观察”是评价和研究相容剂的初始相容性和增塑相容性行之有效的方法。介绍相容剂的选择和用量的确定 ,以及石油沥青聚氨酯防水材料的配方设计。根据所设计配方进行工业化生产的防水材料 ,各项性能指标均达到JC500

Asphalt filled PU waterproofing materials, with excellent performance and moderate costs, will find wide applications, the keypoint of manufacture of which is the choose of the compatablizers. The writer created an effective method to study the compatability, namely 'Drop Test' and 'Surface Contaminating test', the designed waterproofing material has achieved excellent quality and every performance data, according to JC 500-92.
