摘要
Abstract
The polyether and polyester interconnection monomers were synthesized,and the borate ester bonding agents( BE⁃BAs) were synthesized using above interconnection monomers.The interface interaction enthalpies of AP,RDX,HTPB polyurethane ( HTPB⁃PU) matrix and BEBAs were calculated using inverse gas chromatography.The results indicate that the interface interaction enthalpies of BEBAs and AP or RDX are much higher than those of HTPB⁃PU and AP or RDX or BEBAs,which indicates that the BEBAs are preferentially adsorbed on AP or RDX,and the polyester chain segment of BEBA⁃4 is more conducive to the absorption among them.The electron spectroscopy results directly prove that BEBA⁃4 is adsorbed on AP or RDX surface.The interfacial tension and interfacial adhesion between the fillers,the HTPB⁃PU matrix and the fillers coated BEBA⁃4 are measured using the contact an⁃gle method.The results indicate that the interfacial tension between the fillers coated BEBA⁃4 and the HTPB⁃PU matrix is de⁃creased,the interfacial adhesion is increased and the interfacial bond strength is enhanced.The results from the mechanical proper⁃ties testing and SEM observations are greatly in accordance with conclusions from the interfacial adhesion interactions. The result shows that BEBA⁃4 prepared from poly( butylene adipate) can significantly improve the mechanical properties of the HTPB propel⁃lant.关键词
