对于以氧化铜为固化剂改性磷酸铬铝的高温粘结剂，研究了氧化铜粒径、氧化铜含量、固化温度与固化时间对氧化铜-磷酸铬铝粘结剂粘结性能的影响。并采用DSC-TG、XRD、IR分析研究了体系的固化特性和耐热性能。实验结果表明，当氧化铜粒径为55~45μm，含量为基料的15%，在230℃下固化3 h时，其粘结强度最高，达到3.031 MPa。该粘结剂在200~800℃以内时为非晶相，800~1200℃时主要为AlPO4、Al(PO3)3和Cu2P2O73种晶型。

Research the properties of the aluminum-chromium-phosphate high temperature adhesive bonding which is modiifed by copper oxide as the curing agent. The inlfuences of content of copper oxide, Copper oxide particle size, curing temperature and the curing time to the properties of the adhesive bonding are explored. The DSC-TG, XRD and IR were used to detect the Curing characteristics and heat-resistant quality. From experimental results, the bonding strength of the adhesive maximized when the Copper oxide particle size is 55~45μm, the phosphate chrome-alumina content is 15%, and cured at 230℃ for 3 hours. The peak value is 3.031MPa. The main crystal phase of the adhesive at 200~800℃ is amorphous phase, but at the temperature from 800 to 1200, the main crystal form areAlPO4,Al(PO3)3 andCu2P2O7.
