Description
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。
本发明的第二个目的在于提供一种高色牢度用聚氨酯树脂的制备方法,具有操作较为简单且可批量生产,易于实现工业化生产的优点。
本申请的第一个申请目的是通过以下技术方案得以实现的,一种高色牢度用聚氨酯树脂,其特征在于:由包含以下重量份的原料制备而成:20~300份的生成物A、200~250份的聚多元醇、30~50份的扩链剂、10~150份的二异氰酸酯、300~900份的溶剂、0.05~0.60份的终止剂、0.0005~0.0015份的催化剂;生成物A由包含以下重量份的原料制备而成:250~300份的靛蓝、300~850份的二异氰酸酯、300~500份的溶剂。
通过采用上述技术方案,通过靛蓝含有的仲胺基-NH-与异氰酸酯反应,使靛蓝分子完全接到聚氨酯分子中去,并且靛蓝分子中的共轭结构仍然存在,并不会影响靛蓝的显色,这种通过化学键结合而成的显蓝色的聚氨酯树脂,色牢度强,颜色不会随着水洗或者擦拭而退去,本申请只针对于蓝色产品,具有较高的色牢度的优点。
优选的,所述聚多元醇为分子量500~4000g/mol的聚酯二元醇、聚醚二元醇、聚碳酸酯二元醇的一种或两种以上的混合物。
通过采用上述技术方案,可调整所制备的产品的柔韧性、耐磨性、防污染性,耐候性。
优选的,所述扩链剂为分子量61~500g/mol的二醇、二胺或者醇胺的一种或两种以上的混合物。
优选的,所述扩链剂为1,5-戊二醇、1,6-己二醇、乙二胺、DMPA、TMP中的一种或多种。
通过采用上述技术方案,可以使所制聚氨酯树脂产品具有更好的抗老化、耐摩擦、耐候性能。
优选的,所述溶剂为二甲基甲酰胺、甲基乙基酮、甲苯、乙酸乙酯、碳酸二甲酯、丙酮、环己酮、N-甲基吡咯烷酮、异丙醇中的一种或两种以上的混合物。
通过采用上述技术方案,可以使生成的溶剂型聚氨酯树脂有很好的流动性能,便于加工,并且能用现有的车间设备进行正常的烘干处理。
优选的,所述靛蓝与二异氰酸酯的摩尔比为1:1.2~1:10之间。
通过采用上述技术方案,可以使靛蓝分子能够与二异氰酸酯反应,并且保证生成物二异氰酸酯过量,也就是异氰酸酯基团封端。
优选的,还包含以下重量份的原料制备而成:0.05~0.5份的助剂;助剂为表面活性剂、抗氧化剂、紫外吸收剂、耐候稳定剂、防水解剂的一种或者两种以上的混合物。
