Abstract

本发明涉及一种耐酸碱红色母粒，红色母粒由以下成分按照重量比组成：颜料红177为14～18份、苯乙烯为19～22份、甘油为3～4份、特丁基对苯二酚为4～5份、酚醛树脂为7～9份、聚丙烯酰胺为3～5份、石灰石粉为2～4份。制备得到的红色母粒具有良好的耐酸碱性和稳定性。

Description

一种耐酸碱红色母粒
技术领域
本发明涉及一种母粒，特别是涉及一种耐酸碱红色母粒。
背景技术
色母粒具有非常广的应用，可用在塑料中，帮助颜料均匀的分散在体系中。色母粒一般由颜料和树脂混合而成，再添加一些其他分散剂成分后具有良好的性能。在常规的色母粒使用过程中，由于放置时间过长，会产生色母粒性质不稳定的情况发生。同时，由于色母粒不具有耐酸碱性能，在它应用到塑胶中后，会对塑胶的耐酸碱性能产生影响，因此我们需要增强色母粒的耐酸碱性能。
发明内容
要解决的技术问题：常规的色母粒耐酸碱性能较差、稳定性较差的问题。
技术方案：本发明公开了一种耐酸碱红色母粒，红色母粒由以下成分按照重量比组成：颜料红177为14～18份、苯乙烯为19～22份、甘油为3～4份、特丁基对苯二酚为4～5份、酚醛树脂为7～9份、聚丙烯酰胺为3～5份、石灰石粉为2～4份。其中，颜料红177优选为14份；苯乙烯优选为22份；甘油优选为3份；酚醛树脂优选为9份。
耐酸碱红色母粒制备方法如下：称取颜料红177为14～18kg、苯乙烯为19～22kg、甘油为3～4kg、特丁基对苯二酚为4～5kg、酚醛树脂为7～9kg、聚丙烯酰胺为3～5kg、石灰石粉为2～4kg，用双螺杆锥形混合机进行混匀，混匀时间为15min，再使用双螺杆挤压机进行高温混溶，温度为160℃，螺杆转速为150r/min，螺杆挤压高温混匀后，将混合体进行造粒、干燥，得到红色母粒。
有益效果：本发明制备得到的红色母粒具有优异的耐酸碱性能，可耐15wt%的氢氧化镁溶液浸泡10天不发生变化，耐20wt%的柠檬酸溶液浸泡10天不发生变化。另外在室温下放置6个月后，色泽没有发生变化。
具体实施方式
实施例1
称取颜料红177为18kg、苯乙烯为19kg、甘油为4kg、特丁基对苯二酚为4kg、酚醛树脂为7kg、聚丙烯酰胺为5kg、石灰石粉为2kg，用双螺杆锥形混合机进行混匀，混匀时间为15min，再使用双螺杆挤压机进行高温混溶，温度为160℃，螺杆转速为150r/min，螺杆挤压高温混匀后，将混合体进行造粒、干燥，得到红色母粒。
实施例2
红色母粒制备方法同实施例1，具体成分含量如下：颜料红177为16kg、苯乙烯为21kg、甘油为3kg、特丁基对苯二酚为5kg、酚醛树脂为8kg、聚丙烯酰胺为3kg、石灰石粉为3kg。
实施例3
红色母粒制备方法同实施例1，具体成分含量如下：颜料红177为14kg、苯乙烯为22kg、甘油为4kg、特丁基对苯二酚为4kg、酚醛树脂为9kg、聚丙烯酰胺为4kg、石灰石粉为4kg。
制备得到红色母粒后，对红色母粒的耐酸碱性和稳定性进行了考察。实施例1、实施例2、实施例3的红色母粒分别放入15wt%的氢氧化镁溶液浸泡10天，20wt%的柠檬酸溶液浸泡10天。另外在室温下放置6个月。
实施例1、实施例2、实施例3的红色母粒在15wt%的氢氧化镁溶液浸泡10天，20wt%的柠檬酸溶液浸泡10天后，均没有发生改变，具有良好的耐酸碱性。另外在室温下放置6个月后，色泽没有发生变化，也具有良好的稳定性。
