Description

汽车内饰皮革的生产工艺 技术领域：
本发明涉及一种汽车内饰皮革的生产工艺。
背景技术：
人造皮革也叫仿皮或胶皮，是PVC和PU等人造材料的总称。它是在纺织布基或无纺布基上，由各种不同配方的PVC和PU等发泡或覆膜加工制作而成，可以根据不同强度、耐磨度、耐寒度和色彩、光泽、花纹图案等要求加工制成，具有花色品种繁多、防水性能好、边幅整齐、利用率高和价格相对真皮便宜的特点。
现在，人造皮革已被大量制造并应用在包括衣物、鞋子、家具及车辆用材料中。人造皮革的制造一般是使用由一般纤维、超细纤维或一般纤维与超细纤维混结成的不织布作为基布，并在该基布表面上填入聚氨酯树脂组成物，后施以研磨加工或压纹加工或以离型纸涂布聚氨基甲酸酯树脂施以贴合加工，而构成表面具有弹性及真皮纹路的皮料。
目前，汽车内饰主要是指汽车内部改装所用到的汽车产品，涉及到汽车内部的方方面面，比如汽车方向盘套、汽车坐垫，汽车脚垫。在车内跟驾驶员接触时间最长、最紧密的当属方向盘和座椅，而制作方向盘套、坐垫、脚垫使用的皮革在生产过程中使用大量有机溶剂，如二甲基甲酰胺、甲乙酮、甲苯等，这些有机溶剂不仅污染环境，还会发出难闻的气味，使驾驶员感到不适。
发明内容：
本发明的目的是为了克服以上的不足，提供一种成本低、质感好、舒适度佳的汽车内饰皮革的生产工艺。
本发明的目的通过以下技术方案来实现：一种汽车内饰皮革的生产工艺，包括以下步骤：
A、制备针刺无纺布：针刺无纺布属于无纺布的一种，以涤纶、丙纶原料制造，经过多次针刺加以热轧处理而成；
B、在针刺无纺布上涂覆一层PVC发泡层；
C、在PVC发泡层上使用水性处理剂进行处理，最后形成PVC面层；
D、在PVC面层上涂覆一层蜡感油性涂层。
本发明的进一步改进在于：水性处理剂为水性聚氨酯。
本发明的进一步改进在于：蜡感油性涂层由油蜡感皮革手感剂和水混合而成。
本发明与现有技术相比具有以下优点：
本发明采用油蜡感皮革手感剂，油蜡感皮革手感剂是水溶性产品，可用水任意稀释，环保、安全，对设备和通风等环保设施要求低，对健康无伤害；本发明使用水性处理剂处理皮革表面，降低溶剂的残留，除去异味，改善环境，还使得布面更加光滑。
具体实施方式：
为了加深对本发明的理解，下面将结合实施例对本发明作进一步详述，该实施例仅用于解释本发明，并不构成对本发明保护范围的限定。
一种汽车内饰皮革的生产工艺，包括以下步骤：
A、制备针刺无纺布：针刺无纺布属于无纺布的一种，以涤纶、丙纶原料制造，经过多次针刺加以热轧处理而成，针刺无纺布是干法非织造布中一 种，是将短纤维经过开松、梳理、铺成纤维网，然后将纤维网通过刺针加固成布，刺针有钩刺，将纤维网反复穿刺，钩带纤维加固，形成针刺无纺布，无纺布没有经线纬线之分，成布纤维杂乱，径向纬向性能差别不大，针刺无纺布系列产品是经过精细梳理成型，多次精密针刺或加以适当热轧处理而成。在引进国内外二条高精度针刺生产线的基础上，选用优质纤维。通过不同生产工艺配合，以及不同材料的配搭，目前市场上流通数百种不同的产品，其中是人造皮革生产中的基布；
B、在针刺无纺布上涂覆一层PVC发泡层；
C、在PVC发泡层上使用水性处理剂进行处理，最后形成PVC面层，水性处理剂为水性聚氨酯，水性聚氨酯是以水代替有机溶剂作为分散介质的新型聚氨酯体系，也称水分散聚氨酯、水系聚氨酯或水基聚氨酯。水性聚氨酯以水为溶剂，无污染、安全可靠、机械性能优良、相容性好、易于改性等优点，水性聚氨酯可增加皮革的美观和耐用性能，提高档次，增加花色品种、扩大使用范围，其中聚氨酯类涂饰剂的成膜性能好、遮盖力强、粘结牢固，涂层的物理性能优异，可大大提高成革的等级；
D、在PVC面层上涂覆一层蜡感油性涂层，蜡感油性涂层由油蜡感皮革手感剂和水混合而成，油蜡感皮革手感剂是水溶性产品，可用水任意稀释，环保、安全，对设备和通风等环保设施要求低，对健康无伤害。
本发明使用水性处理剂处理皮革表面，降低溶剂的残留，除去异味，改善环境，还使得布面更加光滑。
申请人又一声明，本发明通过上述实施例来说明本发明的实现方法及装置结构，但本发明并不局限于上述实施方式，即不意味着本发明必须依赖上述方法及结构才能实施。所属技术领域的技术人员应该明了，对本发明的任 何改进，对本发明所选用实现方法等效替换及步骤的添加、具体方式的选择等，均落在本发明的保护范围和公开的范围之内。
本发明并不限于上述实施方式，凡采用和本发明相似结构及其方法来实现本发明目的的所有方式，均在本发明的保护范围之内。
