摘　　要：在将TCEP添加到聚氨酯材料后,发现聚氨酯材料的阻燃性能增加,然后在此基础上,又将水泥添加其中,发现聚氨酯的阻燃性能会随着水泥添加量的增加而增加,但是聚氨酯会出现中空现象,影响其物理性能。After TCEP was added to polyurethane material, fire resistance character of polyurethane material was found improved. Then, cement was added, fire resistance character of polyurethane material improved also with cement content adding. But hollow phenomenon was found in polyurethane, which influenced its physical character.
