摘　　要：为提高银粉在有机相中的润湿性,根据Washburn方程,采用透过高度法测定二丙二醇丙醚、丁基卡必醇醋酸酯和松油醇3种溶剂对银粉的润湿角,并在3种溶剂中分别加入辛酸、三乙醇胺、失水山梨醇三油酸酯和BYK182 4种分散剂观察润湿角的变化。结果表明:松油醇对银粉的浸润性最好,将非离子型高分子表面活性剂BYK182加入二丙二醇丙醚和丁基卡必醇醋酸酯2种溶剂中可以改善对银粉的润湿性。To improve the wettability of silver powder in organic vehicle,a measurement of the permeating height,according to the Washburn equation,has been employed to evaluate the wetting angle of silver powder in the following three solvents,Dipropylene glycol n-propyl ether,Diethylene glycol n-butyl ether acetate and α-Terpineol.The change of the wetting angle has been observed when four dispersants,n-Caprylic acid,Triethanolamine,Sorbitan Trioleate,and BYK182 were added in different solvents.The results show that α-Terpineol has the best wettability for silver powder.As a kind of nonionic polymer surfactants,BYK182 improves the wettability in the solvents of Dipropylene glycol n-propyl ether and Diethylene glycol n-butyl ether acetate.
