Description

水性透气鞋面革制备工艺
技术领域
本发明涉一种合成革制造领域，特别是指一种水性透气鞋面革制备工艺。
背景技术
传统的鞋面革表面都是光面，或者在光面上压花形成花纹，然而一些鞋面革需要在表层形成反绒的真皮效果，目前这种带有反绒效果的人造革制作工艺为：上浆；植绒；预烘；真空抽吸；烘焙；真空冷却；刷毛；磨皮；揉软；这种工艺形成的绒面绒层不够牢固，容易掉绒，且绒毛层容易贴在人造革表面，整体仿真皮效果差，透气性也差。
发明内容
为了克服上述缺陷，本发明提供一种水性透气鞋面革制备工艺，采用该工艺方法生产的鞋面革表面具有绒感，仿真皮效果好，透气性好。
本发明为了解决其技术问题所采用的技术方案：一种水性透气鞋面革制备工艺，具体步骤如下：
步骤一：湿法混合配料：
a、将150重量份水性聚氨脂湿法树脂加入反应釜搅拌的同时加入0.5-1.5重量份分散剂，然后缓慢加入10-20重量份木粉搅拌均匀；
b、向步骤a中获得的混合物中加入4-6重量份发泡剂搅拌搅拌均匀，再加入0.5-2重量份水性色浆充分搅拌均匀，然后缓慢加入1-2重量份增稠剂搅拌均匀；
c、对步骤b中获得的混合物进行粘度检测，在低于40度的温度条件下混合物的粘度指标达到20000-25000cps为合格，对检测合格的混合物进行过滤待用；
步骤二：湿法贝斯生产：
将步骤一中过滤好的湿法浆料通过发泡机发泡到1.5-1.8倍率，将发泡后的湿法浆料涂刮在基布上，浸入质量百分浓度为4.5-5％的酸水溶液中进行凝固，然后顺序经过至少一道轧水工序、水洗工序和干燥工序最后得到湿法贝斯；
步骤三：磨皮：
将步骤二中得到的湿法贝斯用砂纸进行表面磨皮，得到带有表面绒感的半成品；
步骤四：表处剂配置:
将100重量份水性表处剂、0.5-3.0重量份消泡剂和0.5-5重量份水性色浆混合后搅拌均匀，再加入1-2重量份增稠剂，增稠至粘度值为20000-25000cps；
步骤五：表处处理:
将步骤三中磨好皮的半成品用步骤四中配置好的表处剂进行表处，然后经烘干得到成品；
步骤六：成品检查。
作为本发明的进一步改进，所述步骤一的a分步中150重量份水性聚氨脂湿法树脂加入反应釜以300-500转/分钟的速度进行搅拌，加入1.0重量份分散剂，然后缓慢加15重量份木粉在反应釜内，反应釜以400-600转/分钟的转速进行搅拌30分钟。
作为本发明的进一步改进，所述步骤一b分步中加入发泡剂后以300-400转/分钟的转速进行搅拌5分钟左右，然后再加入水性色浆。
作为本发明的进一步改进，所述步骤一b分步中缓慢加入增稠剂，并在混合物增稠过程中注意观察分散情况来控制添加的速度，加入增稠剂过程中反应釜转速控制在500-600转/分钟。
作为本发明的进一步改进，所述步骤二中基布在涂刮湿法浆料前先经过温度为130度的热烫轮烫平。
作为本发明的进一步改进，所述步骤二中酸水溶液为草酸水溶液或甲酸水溶液，步骤二中湿法贝斯生产车速在12-14米/min。
作为本发明的进一步改进，所述步骤三中湿法贝斯用180目砂纸进行表面磨皮。
作为本发明的进一步改进，水性表处剂包括100重量份份水性聚氨酯PU树脂、1-2重量份消光粉、1-2重量份手感剂和1-2重量份消泡剂。
作为本发明的进一步改进，步骤五中磨好皮的贝斯用配置好的表处剂，经过120目网纹辊表处，经烘箱烘干得到成品，车速在15-18米/min。
本发明的有益效果是：本发明通过将湿法浆料发泡后再涂覆在基布上形成湿法贝斯，这种湿法贝斯整体弹性好，具有真皮弹性，在其表面通过磨毛的方式形成绒感效果，最终再通过特殊的表处剂对磨绒层进行表面处理，使得磨绒层更具有仿真效果，且本发明材料全部采用水性材料，无需溶剂，有利于身体健康和环保，且本专利生产的人造革透气性好，穿着舒适。
