摘要热塑性弹性体发射药是由高含量固体含能材料(70%~80%,质量分数)、含能/惰性热塑性弹性体(10%~15%,质量分数)及其他工艺助剂组成的非均相体系。与传统的NC/NG体系发射药相比,热塑性弹性体发射药具有能量高、爆温低、力学性能优良、易损性低、可绿色制造等优点,是未来发射药的主要发展方向之一。本毕业论文采用惰性代用料代替黑索金与热塑性弹性体捏合,采用传统单螺杆挤出工艺,辅助压延成型工艺,使样品充分塑化。再测量其密度,以及拉伸强度和弹性模量等物理量,进而反向寻求快速表征含能高分子复合材料塑化程度的方法。本文不仅探索了主要工艺参数对成型效果的影响规律,同时验证了两种试验表征方法的可行性、易行性与正确性。9359

Title The plasticizing properties of energetic polymer composite
Abstract
Thermoplastic elastomer propellant are characterized by high content of solid energetic materials (70%~ 80%, mass fraction), energetic / inert thermoplastic elastomer (10%~ 15%, mass fraction) and other additive process composed of heterogeneous system. With traditional NC / NG propellant, thermoplastic elastomer propellant with high energy, low detonation temperature, excellent mechanical properties, low vulnerability, green manufacturing and other advantages, is the future development direction of the main propellant. This paper adopting inert substitute material instead of RDX and thermoplastic elastomer kneading, using the traditional single screw extrusion process, the auxiliary molding technology, so that the sample is sufficiently plasticized. Then measuring its density, and the tensile strength and elastic modulus and other physical quantities, and then reverse seeking rapid characterization of energetic polymer composite plasticizing degree method. This paper not only research the main process parameters on the forming and the effects of, and validation of two experimental characterization method is feasible, simple and accurate.
