RDX／GAP纳米复合含能材料的制备及热性能
Preparation and Thermal Properties of RDX/GAP Nano-composite Energetic Materials
摘要
Abstract
RDX/GAP composite energetic material was prepared by sol-gel method and solution crystallization method using glycidyl azide polymer (GAP)and hexamethylene diisocyanate(HDI)as raw materials and T-12 as catalyst.Its structure was characterized by BET method,X-ray powder diffraction and scanning electron microscopy and its thermal properties were analyzed by TG/DSC.Results show that RDX/GAP composite energetic material has nano-grid structure and its surface area is much smaller than that of GAP xerogel.The mean particle size of RDX/GAP composite energetic material is 20-50 nm.The thermal decomposition peak temperature of RDX in the composite energetic material is greatly decreased,and the decomposition heat is much higher than that of the physi-cal blend materials.关键词
