研究了不同种类扩链剂对 HTPB/IPDI推进力学性能的影响 ,结果表明 ,加入二醇类、两端含羟基的醚类扩链剂能改善丁羟推进剂力学性能 ,特别是大幅度提高推进剂低温最大伸长率 ;二胺类扩链剂使推进剂抗拉强度显著升高而伸长率显著下降
The effects of different kinds of chain extenders on the mechanical properties of HTPB / IPDI propellants were studied. The results showed that the addition of glycols and hydroxyl-containing ether chain extenders at both ends could improve the mechanical properties of HTPB propellants. In particular, Agent maximum elongation at low temperature; diamine chain extender significantly increased the tensile strength of the propellant while the elongation decreased significantly
