摘要 以乙基纤维素(EC)为原料,乳化剂、增塑剂、水等为辅助材料,采用相转变法制备乙基纤维素水分散体。结果表明:随着乳化剂用量的增加,水分散体表面张力先下降后趋于不变;增加增塑剂的含量能降低水分散体的玻璃化转变温度,但同时减慢了水分散体的固化速率。 Ethylcellulose (EC) latex was fabricated with phase conversion by using EC,emulsification,plasticizer and water. The results showed that the surface tension decreased former and then kept invariable with increasing of the emulsifier. In addition,both Tg and condensate rate of the latex reduced with increasing of the plasticizer content.
