本专利叙述一种含羟基聚丁二烯聚合物和固体氧化剂的高固体含量固体推进剂新配方。这种推进剂的改进是在配方中加入一种少量的有效化合物,提高其适用期,并降低药桨粘度。添加的化合物是从通式为(?)或(?)的化合物中选择的,式中 R 为氢、ω—羟烷基、苯基、环已基,(?)R′为ω—羟烷基或羟苯基;R″为烷基;R′″为烷基或芳香基;m 和 n 为1～20的整数。本发明还叙了述这种固体推进剂配方的拟定方法以及浇注和固化。
This patent describes a new high solids solid propellant formulation containing a hydroxyl polybutadiene polymer and a solid oxidant. The improvement of this propellant is to add a small amount of effective compound to the formulation to improve its pot life and reduce the viscosity of propellant. The added compound is selected from the compounds of the general formula wherein R is hydrogen, ω-hydroxyalkyl, phenyl, cyclohexyl, and R¹ is ω-hydroxyalkyl Or hydroxyphenyl; R “is alkyl; R ’” is alkyl or aryl; and m and n are integers from 1 to 20. The present invention also describes the method of formulation of such a solid propellant formulation as well as casting and curing.
