【摘要】 通过氧化铜、DTPA、HEDP三种材料对粘结剂复合改性，并通过正交试验确定氧化铜、DTPA、HEDP的最优配比分别为2 g、4 g、12 g，也就是得到粘结剂34B6D2C1H6，所制试样相比于基液所制试样，在相对空气湿度50%RH以内存放120 h，抗吸湿性提升46.8%。再通过在制样时添加占粘结剂比例4%的辅料（98收尘镁砂粉），在相对空气湿度60%RH以内存放6 h，试样的抗吸湿性比没加辅料时提升70.5%。更多还原

【Abstract】 In this paper, the binder was modified by the composite modification of copper oxide, DTPA and HEDP, and the optimal proportions of copper oxide, DTPA and HEDP were determined by orthogonal test to be 2 g, 4 g and 12 g, respectively, that is, the binder 34B6D2C1H6 was obtained, and the sample was stored within 50%RH of relative air humidity for 120 h compared with the sample made by the base liquid, and the moisture absorption resistance was increased by 46.8%. By adding auxiliary materials accounting for 4% of the binder ratio(98 dust collection magnesia powder) during sample preparation, and storing them within 60% RH of relative air humidity for 6 h, the moisture absorption resistance of the sample is increased by 70.5% compared with that without auxiliary materials.更多还原
