以磷酸、氢氧化铝、氧化铜等为主要原料,拟制备出具有高粘结性且耐高温氧化的胶粘剂.采用正交试验方法优选出配方,讨论了氧化铜粒径、固化温度、固化时间、氢氧化铝对其粘结性能的影响.验证实验表明:开发的新型高温磷酸盐胶粘剂,制备工艺简单,最佳固化温度为120 ℃,最佳固化时间为4 h;该胶粘剂粘结性能好,耐高温,呈淡黄青色,具有广阔的应用前景.
Some raw materials such as phosphoric acid, aluminum hydroxide and copper oxide were mainly used to prepare adhesive with high bond and heat-resisting, a optimal adhesive formulation was selected through orthogonal experimental method. The effect of copper oxide particle size, curing temperature, curing time and aluminum hydroxide on the bonding properties was discussed. Results show that new phosphate adhesive is provided with simple preparation process, good adhesion, heat-resisting and broad application prospects, and it appeares pale yellow green with curing temperature of 120 ℃ and curing time of 4 h.
