【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。更多还原

【Abstract】 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.更多还原
