2、:以3,3'-二氯联苯胺盐酸盐(DCB)和邻甲基乙酰乙酰苯胺(AAOT)为原料,在偶合反应结束后,向制备的C.I.颜料黄14(PY14)水分散液中添加聚乙烯蜡(PEW),考察了PEW添加量、加热温度、加热时间、搅拌转速、pH、PEW粒径对颜料性能的影响。得到较优制备条件为:PY14与PEW的质量比1.0∶1.0、加热温度80℃、加热时间20min、40~60目PEW、pH=7.0、转速250r/min,在该条件下制备出直径为1~2mm、粒径均一、具有核壳结构和疏水性能的预分散C.I.颜料黄14(
3、预分散颜料PY14)。预分散颜料易于从水相分离,滤饼含水量从PY14颜料的79.29%降低至预分散颜料PY14的59.85%,过滤时间为PY14颜料的1/20;分散过滤值(FPV)从PY14颜料的0.75MPa/g降低至预分散颜料PY14的0.06MPa/g;所得颜料不需经过强力粉碎,可抑制粉尘污染的产生;在保持与原颜料相近的色光、饱和度、鲜艳度等颜料性能前提下,提升了颜料的着色力。关键词:C.I.颜料黄14;聚乙烯蜡;预分散;疏水性能;核壳结构;特种染料与颜料中图分类号:TQ620.6文献标识
