摘要：为了提高铜金粉的表面其泽度采用3种表面活性剂对铜金粉进行表面改性研究,从而证明降低粘结料对铜金粉的润湿性,可提高粉末在粘结料中的漂浮性能,有效提高铜金粉颜料的印金光泽度。探明了铜金粉颜料化处理的原理和努力的方向。同时分析了表面活性剂的种类及其浓度对铜金粉印金光泽度的影响。结果表明,铜金粉的润湿性随表面活性剂浓度变化而存在极值点;复合改性剂比硬脂酸系列的改性剂能更好的降低铜金粉的润湿性。

Abstract：In order to give the particularly bright visual effect,the surface modification of bronze powder were done by using three kinds of surfactants to improve the leafing degree of the powder in the application medium.It shows that the degree of floatage in vehicle system will depend on the ability of that vehicle system to wet the flakes;the greater the wetting,the poorer the floating.It proves up the principle of bronze powder treatment and the direction for getting quality bronze powder.The kinds and concentrations of surfactant influencing print glossiness of bronze powder were analyzed.The results indicate that bronze powder will have the lowest wetting degree at the optimum concentration of surfactant,and bronze powder modified with the third kind of surfactant has the highest print glossiness.
