摘要
以异佛尔酮二异氰酸酯(IPDI)、聚氧化丙烯二醇(PPG)、苯乙烯(St)、甲基丙烯酸丁酯(BMA)和丙烯酸丁酯(BA)等为主要原料,采用种子乳液聚合法合成了WPU/SBB(水性聚氨酯/苯丙)复合乳液;然后以此为高能炸药——HNIW(六硝基六氮杂异伍兹烷)颗粒的包覆剂和胶粘剂。采用红外光谱(FT-IR)法、X-射线衍射(XRD)法及差示扫描量热分析(DSC)法等手段对WPU/SBB复合乳液的结构进行了表征,并采用扫描电镜(SEM)、特性落高值(H50)和X-射线光电子能谱(XPS)法等分析了WPU/SBB复合乳液对HNIW的包覆效果。结果表明:包覆后HNIW的H50由13.6 cm升至34.8 cm,说明该环保型WPU/SBB复合乳液对HNIW具有明显的降感作用。
With isophorone diisocyanate (IPDI), polyoxy propylene glycol (PPG), styrene ( St ), methyl butyl acrylate(BMA) and butyl acrylate(BA) as main raw materials,a WPU/SBB(waterborne polyurethane/styrene-acrylate) composite emulsion,which was used as coating agent and adhesive of a hexanitrohexaazaisowurtzitane (HNIW) high explosive,was synthesized by seed emulsion polymerization. The structure of WPU/SBB composite emulsion was characterized by FT-IR(Fourier transform infrared spectroscopy),XRD(X-ray diffraction) and DSC(differential scanning calorimetry) methods,and the effect of HNIW coated by WPU/SBB composite emulsion was analysed by SEM (scanning electron microscopy),H50(characteristics critical height-value) and XPS (X-ray photoelectron spectroscopy) methods. The results showed that the environment-friendly WPU/SBB composite emulsion had obvious action in decreasing impact sensitivity of HNIW because the H50 of coated HNIW was increased from 13.6 cm to 34.8 cm.
