Description

一种水性低温印刷环保型聚氨酯合成革的制备方法
技术领域
本发明涉及一种功能性聚氨酯的制备工艺，具体涉及一种水性低温印刷聚氨酯合成革的制备方法，属于聚氨酯合成革技术领域。
背景技术
聚氨酯(PU)合成革是一类具有特殊性能的新型高分子复合材料，被广泛应用于男女鞋、时装鞋、工作鞋、劳保鞋、童鞋、运动休闲鞋、沙发家俱、办公椅、按摩椅、手袋、证件、文具、球类及体育用品、电子包装、室内和工程装饰、汽车内饰等领域。
为了满足不同消费群体对产品外观和品质的要求，需要对其进行印刷涂饰处理。但印刷用的涂饰剂一般都为溶剂型体系，溶剂型体系含有大量的有机溶剂，有机溶剂会对人的身体健康和环境造成不利影响。而水性印刷体系黏度低，流动性好，不使用有机溶剂，与溶剂型印刷体系相比，VOC含量极低，大大改善了印刷操作者的工作环境，降低了有害物质对他们身体的危害，成为发展趋势。
但水性印刷体系相比于成熟的溶剂型印刷体系，往往耐水、耐热和耐老化等耐久耐用性能较差，需要加入水性固化剂，提高印刷层的交联度，用以保证产品的物性。常用的水性交联剂包括氮丙啶交联剂和水性异氰酸酯交联剂，氮丙啶交联剂常温就可以缓慢固化，用过的料不能长期存放，料的损耗成本很高，而水性异氰酸酯交联剂的固化温度则需要150℃以上，需要大量的能耗。
节能环保是现代社会必须面对的重大课题，印刷涂饰工作一般需要在烘箱中用较高的温度固化，能耗较大。因此，从现实上考虑，在较低的温度下实现印刷涂饰层的固化具有重要的意义。传统的水性聚氨酯印刷工艺需要较多的水分充当分散剂，水分的烘干需要耗费大量的能量，因而通过工艺方法减少水分的使用，能够降低能耗。
发明内容
本发明针对上述现有技术所存在的问题，提供了一种水性低温印刷聚氨酯合成革的制备方法。本发明采用100-115℃解封的封闭型水性固化剂，使得印刷用水性聚氨酯浆料在较低的温度下进行充分固化；同时本发明采用高固工艺，减少了水的参与，在聚氨酯合成革表面形成高度交联的聚氨酯保护层，保障聚氨酯合成革较高的耐久耐用性，通过低耗能的的高固型工艺制备了水性环保型耐久耐用型聚氨酯合成革。
本发明水性低温印刷聚氨酯合成革的制备方法，包括如下步骤：
步骤1：在离型纸上涂覆聚氨酯面层浆料，涂覆厚度0.1-0.2mm，于115-125℃干燥1.5-3min，制得面层复合膜；
步骤2：在步骤1获得的面层复合膜上均匀涂覆粘结层浆料，涂覆厚度0.2-0.3mm，于90-110℃干燥1-2min，涂层保留一定的粘接性；
步骤3：在步骤2获得的粘接层上贴合布基材料，然后于130-145℃干燥4-6min，干燥熟化后剥离离型纸，获得半成品革坯革；
步骤4：通过涂饰辊在半成品革坯革的表面印刷聚氨酯浆料，在100-115℃下进行反应，车速为8-14m/min，并于130℃下烘干，得到水性高固印刷聚氨酯合成革。
步骤1中，所述聚氨酯面层浆料的组分按质量份数构成如下：100份聚氨酯树脂，0.5份抗黄变助剂，1份固化剂，5-10份色浆。
其中，所述聚氨酯树脂为芳香族聚酯型聚氨酯(如安利新材料AL-1026)、聚醚型聚氨酯(如安利新材料AL-3051)、聚碳酸酯型聚氨酯(如上海汇得HD-5035YC.5025NY)中的一种或多种。所述固化剂为聚丙烯酸酯改性的亲水型异氰酸酯复合物。
步骤2中，所述粘结层浆料的组分按质量份数构成如下：100份多元醇A料，50-70份异氰酸酯B料(AL-5040或Basf B)，0.5份有机金属催化剂，0.1份胺类催化剂。
其中，所述多元醇A料为聚酯型多元醇(如bsfA、AL-5090等羟值在45-70之间的聚酯多元醇)、聚醚多元醇(如陶氏的VORANOLTM系列)、聚碳酸酯多元醇(如上海汇得5035YC.5035NY)中的一种或多种，其羟值为200-300。所述有机金属催化剂为有机铋或有机锡类催化剂中的至少一种。
步骤4中，所述聚氨酯浆料的组分按质量份数构成如下：100份水性聚氨酯浆料，10-14份水，1-2份表面活性剂，1-2份固化剂，4-5份色浆。
其中，所述水性聚氨酯浆料(宁德市一帆新材料有限公司YF-0304A)的分子量为2000-3000；所述表面活性剂为含硅表面活性剂SY-8009:起到润湿作用；所述固化剂为水性封闭型低温解封固化剂(上海腚恺6080B：增加印刷料与革面的附着力，提高耐酒精、耐水解)。
本发明使用的水性封闭型低温固化剂在常温下不解封，在100-115℃即解封，发生固化反应，相比于传统水性固化剂155℃的反应温度，大幅度降低，降低了生产能耗和环境污染。
本发明所用印刷用水性聚氨酯浆料能够在聚氨酯合成革表面形成高密度的聚合物交联网络，形成有效的保护层，增加聚氨酯合成革材料的耐久耐用性。
本发明采用高固工艺，生产过程水添加少，固含量高，能够有效保证产品的饱满度和花纹的立体感。
与现有技术相比，本发明的有益效果体现在：
本发明采用低温解封的水性固化剂用于印刷表处，具有固化温度低、能耗低的特点，所述产品固含量为45％(固含量越高，纹路清晰度越好，流动性越差)，产品手感好，花纹立体感强，耐久耐用性好，可用在沙发家具、鞋、箱包、装饰用品和电子包装中。
本发明所得产品耐酒精，耐水解(70℃*95％RH,5周后革面不开裂、不粉化，剥离强度≥30N/3cm，常温曲挠10万次不开裂，威仕博耐磨10万次革面无破损)且根据ISO16189的检测方法，测试出DMF含量ND。
