Description

具有香味的人造革的制备方法
技术领域
本发明涉及一种具有香味的人造革的制备方法。
背景技术
随着世界人口的增长和经济的快速发展，天然皮革不能满足人们的正常需求，合成皮革由于性价比高，可设计加工性强，易于批量生产，在很多方面替代天然皮革，广泛应用于服装、制鞋、箱包、家具、汽车内饰等行业。
但人造革制品往往散发出一种化学试剂的味道，这增加了人们使用时的不适性。因此，需要设计一种方法，改善人造革的味道，以增加人们使用的舒适度。
发明内容
针对上述技术问题，本发明设计开发了一种可散发香味的具有香味的人造革的制备方法。
本发明提供以下技术方案：
一种具有香味的人造革的制备方法，包括：
步骤(1)在水性PU面层上涂刮一层水性PU发泡层，发泡层的厚度为0.1～0.2mm，加热温度为100～112℃，加热时间为30～35min；
步骤(2)在发泡层上涂刮水性PU胶黏剂，将基布贴在发泡层上，并且使水性PU胶黏剂渗透过基布，再进行加热，加热温度为140～143℃，加热至使水性PU胶黏剂处于半干的状态；
步骤(3)将香味剂涂覆于渗透过基布的水性PU胶黏剂上，形成香味剂层，并且边涂覆边震荡，涂覆速度为2～3cm3/s，震荡频率为10～20次/min，其中，香味剂为由β-环糊精和香精颗粒混合而成，香精颗粒的粒径为1～2mm；
步骤(4)将水性聚氨酯和交联剂涂覆于香味剂层上，加热，加热温度为150～160℃，加热时间为1～2h，从而使水性聚氨酯和交联剂交联形成装饰层。
优选的是，所述的具有香味的人造革的制备方法中，所述步骤(1)中，发泡层的厚度为0.15mm。
优选的是，所述的具有香味的人造革的制备方法中，所述步骤(1)中，加热温度为110℃，加热时间为30min。
优选的是，所述的具有香味的人造革的制备方法中，所述步骤(2)中，加热温度为140℃。
优选的是，所述的具有香味的人造革的制备方法中，所述步骤(4)中，加热温度为156℃，加热时间为1h。
优选的是，所述的具有香味的人造革的制备方法中，所述步骤(3)中，所述香精为玫瑰香精或薰衣草香精。
本发明改善了人造革的味道，使其在使用时能够自然散发出香味，从而增加了人们使用的舒适度。
具体实施方式
下面对本发明做进一步的详细说明，以令本领域技术人员参照说明书文字能够据以实施。
本发明提供一种具有香味的人造革的制备方法，包括：
步骤(1)在水性PU面层上涂刮一层水性PU发泡层，发泡层的厚度为0.1～0.2mm，加热温度为100～112℃，加热时间为30～35min；
步骤(2)在发泡层上涂刮水性PU胶黏剂，将基布贴在发泡层上，并且使水性PU胶黏剂渗透过基布，再进行加热，加热温度为140～143℃，加热至使水性PU胶黏剂处于半干的状态；
步骤(3)将香味剂涂覆于渗透过基布的水性PU胶黏剂上，形成香味剂层，并且边涂覆边震荡，涂覆速度为2～3cm3/s，震荡频率为10～20次/min，其中，香味剂为由β-环糊精和香精颗粒混合而成，香精颗粒的粒径为1～2mm；
步骤(4)将水性聚氨酯和交联剂涂覆于香味剂层上，加热，加热温度为150～160℃，加热时间为1～2h，从而使水性聚氨酯和交联剂交联形成装饰层。
本发明中，水性PU胶黏剂浸透过基布，加热时，使水性PU胶黏剂处于半干的状态，这样香味剂会部分地与水性PU胶黏剂混合在一起，并且在水性PU胶黏剂的粘附作用下而保持在基布与装饰层之间。香味剂这样的涂覆方式可以保证香味剂缓慢地被释放到空气中，而不会迅速地消散，从而保证所制备得到的人造革经过长时间使用仍然能够释放香气。
而且，香精颗粒的粒径为1～2mm，通过震荡，香精颗粒会镶嵌进水性PU胶黏剂中。在形成装饰层之后，香精颗粒会缓慢地挥发变小，使香味逐渐发散出来。
本发明的人造革在100℃下烘烤200个小时，香味仍留存59％。
优选的是，所述的具有香味的人造革的制备方法中，所述步骤(1)中，发泡层的厚度为0.15mm。
优选的是，所述的具有香味的人造革的制备方法中，所述步骤(1)中，加热温度为110℃，加热时间为30min。
优选的是，所述的具有香味的人造革的制备方法中，所述步骤(2)中，加热温度为140℃。
优选的是，所述的具有香味的人造革的制备方法中，所述步骤(4)中，加热温度为156℃，加热时间为1h。
优选的是，所述的具有香味的人造革的制备方法中，所述步骤(3)中，所述香精为玫瑰香精或薰衣草香精。
尽管本发明的实施方案已公开如上，但其并不仅仅限于说明书和实施方式中所列运用，它完全可以被适用于各种适合本发明的领域，对于熟悉本领域的人员而言，可容易地实现另外的修改，因此在不背离权利要求及等同范围所限定的一般概念下，本发明并不限于特定的细节。
