摘要
硫酸钙晶须作为一种新型阻燃材料,是否可以用来研制阻燃沥青值得研究。通过理论和试验分析,证明以硫酸钙晶须作为阻燃剂而研发的阻燃沥青,不仅有很好的阻燃效果,而且硫酸钙晶须的添加还提高了沥青的软化点,降低了沥青的针入度,明显改善了沥青的耐高温性能。
Calcium sulfate whisker is a new type of flame retardant materials. It deserves research thatwhether it can be used to develop flame retardant asphalt. Through theoretical and experimental analy- sis, it is proved that the flame retardant asphalt which is developed by using calcium sulfate whisker as flame retardant not only has good flame retardant effect, but also can improve asphalt softening point, reduce the asphalt penetration, and improve the high temperature performance of asphalt.
