均匀共沉淀法制备铜铬黑色料

Preparation of Copper Chrome black pigment by homogeneous co-precipitation

本文采用氯化铜和氯化铬为原料,以氨水和尿素分别作为沉淀剂,选用聚丙烯酸铵作为分散剂,通过均匀共沉淀法制备铜铬黑色料。从烧成温度、沉淀剂种类、分散剂用量等几个方面来探讨影响铜铬黑色料呈色的因素。

The copper chromite black pigment was successfully prepared by the homogeneous coprerition , which selected copper chloride and chromic chloride as reactants, aqueous ammonia or urea as a precipitation agent, ammonium polyacrylate as a dispersant agent. And this paper is about to discuss the very factors which effect chromogenic of copper chromium black, such as sintering temperature, precipitation agent, amount of dispersant agent, etc.
