Description
本发明涉及一种水性漆及其制备方法，具体涉及一种皮革用水性漆及其制备方法，属于涂料领域。
进入21世纪以来环境保护越来越受到世人的关注，在涂料工业领域，溶剂型涂料含有大量的挥发性有机溶剂(VOC)，在使用过程中排入大气，不仅破坏大气环境，危害人们健康，同时也浪费资源，浪费能源。目前，一般将水性涂料、粉末涂料、高固分涂料以及辐射固化涂料称为环保涂料。
以水溶性树脂或水分散性树脂，包括合成聚合物乳液为基料的涂料均称为水性涂料。因此水性涂料也常称为水基涂料。合成聚合物乳液为基料的涂料均称为水性涂料。
皮革漆目前用于电子类外观部件加饰，增加其目视感观和手感的舒适性，预计未来会广泛用于日常生活用品表面处理，增加使用者的舒适度。现有技术中，皮革漆喷涂中经常添加有机填料，气味难闻，对员工身体不好，不够环保，而发展环保涂料是目前国内涂料行业发展的方向之一，主要是减少有机溶剂的排放、减少环境污染。
现在皮革上一直应用传统的油漆产品，主要成分为二甲苯、丁醇、石油树脂等，属于易燃易爆品，VOC严重超标，环保形势下属于禁用产品，现在大力倡导环保安全，全部改换成环保水性漆产品是必然趋势。水性漆在皮革上易爆皮脱落，附着力达不到、防腐性能达不到等弊病。
有鉴于此，本发明提供了一种皮革用水性漆及其制备方法，具体采用如下技术方案：
一种皮革用水性漆，包括以下重量份数的原料：
水性鞣酸聚氨酯树脂45-60份，水性柔性丙烯酸乳液20-30份，色浆15-20份，消泡剂3-5份，流平剂2-5份，润湿剂2-10份，分散剂8-15份，防腐剂2-8份，附着力促进剂3-10份。

优选的，包括以下重量份数的原料：水性鞣酸聚氨酯树脂45-55份，水性柔性丙烯酸乳液20-25份，色浆15-18份，消泡剂3-4.5份，流平剂2-4.5份，润湿剂2-5份，分散剂8-10份，防腐剂2-5份，附着力促进剂3-6份。
进一步，色浆为无机色浆。
进一步，消泡剂为TSA-10A；
流平剂为SN-3094；
润湿剂为SN-3711；
分散剂为XN3800；
防腐剂为MKB3；
附着力促进剂为TL-BPA。
本发明还提供了上述皮革用水性漆的制备方法，，包括以下步骤：
1）按上述重量份数称取原料；
2）将水性鞣酸聚氨酯树脂、水性柔性丙烯酸乳液进行混合，搅拌均匀；
3）向混合物中加入色浆，继续搅拌；
4）向搅拌后的混合物中依次加入消泡剂、流平剂、润湿剂、分散剂、防腐剂、附着力促进剂，搅拌均匀即得皮革用水性漆。
进一步，步骤2）中所述搅拌的转速为800-1000转/分钟，搅拌时间为20-30分钟。
进一步，步骤3）中所述继续搅拌的转速为200-500转/分钟，搅拌时间为5-10分钟。
进一步，步骤4）还包括加入消泡剂、流平剂、润湿剂、分散剂、防腐剂、附着力促进剂的同时进行搅拌的操作。
本发明的有益效果在于，本发明以水作溶剂，节省大量资源，不含苯、二甲苯、乙烷、甲醛等VOC有害物质，防腐性能优良，复涂性能良好，抗辐射，不经过任何研磨程序，直接搅拌即可，制备方法简单可靠，消除了施工、储存时火灾隐患，降低了对大气污染，在密闭环境中也可照常施工。本发明在皮革表面附着力强，耐候性强，操作性能简单，涂装工具可用水直接清洗，大大有效减少对施工人员的伤害，可以在皮革上运用广泛，可在室外大面积施工，方法简单易施工（喷涂、刷涂、滚涂、静电喷涂等）。
