Description

一种合成革用彩色聚氨酯树脂及其制备方法
技术领域
本发明涉及合成革用材料技术领域，特别涉及合成革用彩色聚氨酯树脂及其制备方法。
背景技术
在合成革用材料着色方面，现在主要使用是将颜料制品或染料制品直接加入合成革用聚氨酯树脂中，经过搅拌，将颜料制品或染料制品与聚氨酯树脂充分混合，以达到聚氨酯树脂着色的目的。由于所使用的颜料或染料对聚氨酯的着色只是混合着色，颜色的固定只是物理过程，而没有化学接合，颜料或染料在树脂中处于游离状态，故极易造成颜色的迁移等诸多问题。染料基本是以分子状态溶解于树脂体系中，单个的小分子状态的染料很容易迁移，但是染料着色鲜艳且透明。颜料在聚氨酯树脂中的稳定性会优于染料，很大程度是因为颜料是大分子结构，且以颜料微粒的形式分散于树脂中，因此颜料着色不容易迁移，但是颜色的鲜艳度和透明性不如染料。
本发明着力于解决，聚氨酯树脂制品同时具有染料的鲜艳性和透明性，又能稳定在聚氨酯产品内部，不游离不迁移。本发明的解决方案，是发明带有发色基团的聚氨酯树脂，使用该树脂的聚氨酯制品，不用另加着色剂。
本发明之前合成革用彩色聚氨酯树脂类似的相关发明专利主要有：
CN86106149 公开了一种着色的热塑性树脂制品及一种热塑性树脂的着色方法。其发明原理为将染料接入环氧基团进行改性，改变染料的分子结构，使着色后不容易产生颜色迁移，再将改性后的染料与树脂进行物理共混，以达到着色的目的。
 CN86106149与本发明的区别在于，CN86106149将染料进行改性，改变染料分子结构以改善染料用于热塑性树脂着色后的迁移性能，其仍为树脂的着色剂。
中国发明专利申请（申请号：201210376000.2 申请日：2012-09-29）公开了一种彩色聚氨酯乳液的制备方法，包括以下步骤：（1）将异氰酸酯、聚醚多元醇和聚酯多元醇反应制得预聚体；（2）将第（1）步制得的预聚体与彩色小分子扩链剂、普通小分子扩链剂、亲水扩链剂进行扩链反应；（3）用成盐剂中和，加水分散乳化，减压蒸馏除去有机溶剂，得到彩色水性聚氨酯乳液。本方法由于利用彩色小分子扩链剂参与扩链反应，制得的彩色聚氨酯乳液整体性能较好，固含量分布宽且可调，产品中有害物质的残留少。
发明内容
本发明的目的在于针对传统合成革用着色材料的不足，本发明的一个目的是提出了一种合成革用彩色聚氨酯树脂，该树脂不会发生色迁移，解决了普通聚氨酯树脂染色后染料容易迁移的问题，又解决了合成革用颜料着色造成的颜色不够艳、通透的问题。本发明的第二个目的是提供上述的聚氨酯树脂的制备方法。
