Description

一种高色牢度用聚氨酯树脂及其制备方法
技术领域
本申请涉及聚氨酯树脂制造技术领域,尤其是涉及一种高色牢度用聚氨酯树脂及其制备方法。
背景技术
我国合成革的生产近20年来,发展极为迅速,已具有相当的产业规模和竞争实力。特别是近几年,我国PU革市场的年增长幅度达17%~29%,己逐渐成为推动全球PU革发展的主要动力之一,甚至也成为促进整个聚氨酯市场发展的主要动力。据不完全统计,2007年全国合成革产量为28亿㎡,2008年为33.2亿㎡,2010年,我国人造革、合成革的生产厂家已达2600多家,其中规模以上企业316家,生产线和产量已占据世界总产量的73%,合成革产量达56亿㎡。比我国GDP增长率高出近一倍,显示出我国合成革产业强劲的增长态势。
聚氨酯树脂保温性能好,软质泡沫弹性好、透气性优良,并具有耐低温、高强度、耐油的特点,在各个领域都有应用。产品形态多样,有泡沫塑料、弹性体、涂料、胶粘剂、纤维、合成革、防水材料以及铺装材料等。
各种聚氨酯制品,通过添加各种色料,展现出各种鲜艳的颜色。目前各种色料主要是与聚氨酯树脂进行共混,色料和聚氨酯通过分子间作用力结合在一起。上述中的现有技术方案存在以下缺陷:现有技术的物理结合力不高,所以存在着随着水洗说着擦拭次数过多,颜色逐渐变淡退去的情况,因此,现有技术存在色牢度较高,水洗颜色易变淡退去的问题。
发明内容
为了解决现有技术存在色牢度较高,水洗颜色易变淡退去的问题,本申请的第一个目的在于提供一种高色牢度用聚氨酯树脂,本申请只针对于蓝色产品,具有较高的色牢度的优点。
