Description

季铵盐衍生物在红颜料制备中的应用、红颜料及制备方法
本申请要求于2021年11月17日提交中国专利局、申请号为CN202111364893.4、发明名称为“季铵盐衍生物在红颜料制备中的应用、红颜料及制备方法”的中国专利申请的优先权,其全部内容通过引用结合在本申请中。
技术领域
本申请涉及水性UV油墨用颜料生产技术领域,具体地说是季铵盐衍生物在红颜料制备中的应用、红颜料及制备方法。
背景技术
近年来,印刷行业的绿色印刷的呼声日益严格,对油墨要求越来越严格,这样水性UV油墨的优势也越来越明显。因此,不管是保护环境,还是应用效果,都显现出环保水性UV油墨上涨趋势。美国、日本、韩国等国家也在大力推广使用环保水性UV油墨。水性UV颜料将是未来环保油墨的最佳选择,发展前景非常广阔。颜料作为印刷油墨的重要原料之一,不仅为油墨提供必要的鲜明色彩,其着色力、粘度、光泽等指标更是会直接影响到水性UV油墨的品质。
现有技术中,红颜料主要由3-氨基-4-甲氧基苯甲酰苯胺(KD-贝司)重氮盐与N-(4-氯-2,5-二甲氧基苯基)-3-羟基-2-萘甲酰胺(AS-LC)和3-羟基-N-(2-甲基-5-二氯基苯基)-2-萘甲酰胺(AS-KB)化合物的混合物而制得。将此类红颜料应用于水性UV油墨时,分散性不好、粘度高、存放稳定性差。
现有技术中曾有在油墨中直接加入季铵盐衍生物的做法,但季铵盐衍生物与油墨中的颜料是物理混合,会导致油墨出现结晶成团等不良现象,因此还需要在制备油墨时另外添加表面活性剂、分散剂和高分子助剂等来改善油墨的性能,提高了油墨的生产成本。

与现有技术相比,本申请具有以下突出的有益效果:
(一)应用于水性UV油墨的红颜料生产中添加季铵盐衍生物CAS号为107-64-2,由于在颜料分子结构上引入了烷基、C 1-8双取代氨基,从而增强了颜料化合物分子本身应用性能,通过氢键、极性作用、范德华力等亲和作用而形成的“锚固”作用,使颜料粒子分散于载体中,让衍生物极性大的偶极矩与现有的同类不含有极性基团的化合物相比发生了本质性改善,形成新生的颜料粒子表面被载体包覆,防止颜料粒子的再聚集,从而提高了颜料在油墨中的润湿性、分散效果和分散稳定性。因此利用季铵盐衍生物制备水性UV油墨用颜料有更明显的应用前景和更好的应用性能。
(二)在颜料反应中引入阴离子表面活性剂,阴离子表面活性剂在颜料碱性溶液中可以溶解,对颜料的润湿性略有改善;如果仅引入非离子表面活性剂,非离子表面活性剂在颜料碱性溶液中不溶解,所以,加入颜料合成中没有效果,反而使颜料不透明,常规生产中不会使用非离子表面活性剂。本申请中阴离子表面活性剂与非离子表面活性剂按1:(1~4)比例混合复配,它在颜料碱性溶液中溶解,颜料润湿效果较好,引入表面活性剂对颜料进行表面处理,控制颜料颗粒排列。根据颜料聚合度越小水溶性越大的原理、颜料粒径的大小与分布、颗粒的物理形态与表面极性特征,使颜料在水性UV体系中分散有着较高的着色强度、较低的粘度及较好的存放稳定性。阴离子表面活性剂和非离子表面活性剂的重量比优选为1:(1~4),以达到调整颜料光泽和透明度的目的。
(三)如果在颜料合成过程中不添加季铵盐衍生物,只添加15~20%的阴离子表面活性剂,颜料在油墨中分散效果不好。本申请添加季胺盐衍生物不仅能改善颜料在应用介质中的分散性,还能降低颜料在油墨中的粘度和粘度存放稳定性。在制备水性UV油墨用颜料的过程中加入季铵盐衍生物后最大限度地降低表面活性剂、分散剂和高分子助剂的使用量,将原来表面活性剂用量由15~20%降低到AS组分重量的0~3%。在保证产品质量的前提下,最大幅度降低颜料的生产成本。也能在制备油墨时减少表面活性剂、分散剂和高分子助剂的使用量,降低油墨的生产成本。

Figure PCTCN2022132222-appb-000002
PR184颜料化学结构式为式(1)+式(2)的混合物。
实例1/5/6/7/9/10/11/12/16对比分析,由于阴离子表面活性剂溶于水,在红颜料中可以反应,单独使用会使颜料透明度稍小,着色力低。非离子表面活性剂不溶、微溶于水,在溶液中有不透明或絮状物,着色力较低,透明度较小,粘度高。因此,取1:1复配液溶解透明,着色力高,透明度大,粘度近似标准。复配液加入位置不同时,红颜料与实例1比较结果近似。
实例1/2/3/4对比分析,随着季胺盐衍生物加入量的减少,颜料粘度增高,着色力降低。
实例1/13/14对比分析,实例中N-(4氯-2,5-二甲氧基苯基)-3-羟基-2-萘甲酰胺(AS-LC)和3-羟基-N-(2-甲基-5-二氯基苯基)--2-萘甲酰胺(AS-KB)添加比例不同,色相变化较蓝或较黄,色力均较低,因此,实例1的比例最佳。
实例1/15对比分析,季胺盐衍生物添加红颜料的色浆中,着色力较低。添加在偶合液中,粘度较低。
实例1/17对比分析,在红颜料中添加脂肪酸铵盐与十二烷基酚1:1复配液,结果近似实例1,因此,优选阴离子表面活性剂和非离子表面活性剂可以进行互换应用。
