在以室温硫化（RTV）硅橡胶为基的低特征信号绝热层材料研制过程中,选用了高含氮物质联二脲（LDA）和有机纤维Kevlar作为阻燃消烟剂。试验结果表明,无论是单独使用,还是复配使用,随着配方中二脲和Kevlar含量的增加,绝热层材料对激光、可见光、红外信号的透过率得到提高,材料的力学性能（拉伸强度和伸长率）则下降。
The flame retardant of LDA and organic fiber-Kevelar are selected during the development of low signal insulation. The basic material of insulation is RTV silicone rubber. The results show that with the increasing of LDA and/or Kevelar in the insulation,the insulation's signature penetrating rate of la- ser,visible light,infrared ray can be increased,but it's mechanical properties decrease.
