摘要: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 质量比 1.0∶1.0、加热温度 80 ℃、
加热时间 20 min、40~60 目 PEW、pH=7.0、转速 250 r/min,在该条件下制备出直径为 1~2 mm、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(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 0.75 MPa/g 降低至预分散颜料 PY14 的 0.06 MPa/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。

Abstract: Using 3,3-dichlorobenzidine hydrochloride (DCB) and o-methylacetoacetylaniline (AAOT) as
raw materials, polyethylene wax (PEW) was added to the aqueous dispersion of C.I. pigment yellow 14
(PY14) after the coupling reaction. The effects of adding amount of PEW, heating temperature, heating time,
stirring speed, pH value, and particle size of PEW on the properties of pigment were investigated. A
pre-dispersed PY14 with a diameter of 1~2 mm, uniform particle size and nuclear-shell structure and
hydrophobic property was prepared under the optimal conditions of mass ratio of PY14 to PEW 1.0∶1.0,
heating temperature 80 ℃, heating time 20 min, particle size of polyethylene wax 40~60 mesh, pH=7.0,
stirring speed 250 r/min. The pre-dispersed PY14 was easy to separate from the water phase. For PY14, the
water content of the filter cake was 79.29%, while that was only 59.85% for the pre-dispersed PY14. The
filtration time of the pre-dispersed PY14 was 1/20 of that of PY14. The filter pressure value (FPV) was
reduced from 0.75 MPa/g to 0.06 MPa/g. The obtained pre-dispersed PY14 do not need to be strongly
pulverized, which can restrain the generation of dust pollution. In addition, this preparation method can
improve the colouring strength of pigment on the premise of maintaining the performances of pigment such
