    摘要:

    為提高銀粉在有機(jī)相中的潤濕性，根據(jù)Washburn方程，采用透過高度法測定二丙二醇丙醚、丁基卡必醇醋酸酯和松油醇3種溶劑對銀粉的潤濕角，并在3種溶劑中分別加入辛酸、三乙醇胺、失水山梨醇三油酸酯和BYK182 4種分散劑觀察潤濕角的變化。結(jié)果表明：松油醇對銀粉的浸潤性最好，將非離子型高分子表面活性劑BYK182加入二丙二醇丙醚和丁基卡必醇醋酸酯2種溶劑中可以改善對銀粉的潤濕性

    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
