Description

一种适用于合成革的水性揉纹助剂
技术领域：
本发明涉及合成革功能助剂技术领域，具体涉及一种适用于合成革的水性揉纹助剂。
背景技术：
合成革，模拟天然革的组成和结构并可作为其代用材料的塑料制品。通常以经浸渍的无纺布为网状层，微孔聚氨酯层作为粒面层制得。其正、反面都与皮革十分相似，并具有一定的透气性，比普通人造革更接近天然革，广泛用于制作鞋、靴、箱包和球类等。
合成革揉纹是通过水、温度和机械力的作用使基布发生收缩，带动表面树脂膜收缩，使花纹的凹凸感更清晰。并且，由于收缩的无定向性，表面花纹产生类似真皮的无规则性，效果更自然逼真。揉纹的同时也是进行机械做软的过程，通过机械力的作用使纤维更加松散，基布变得更加柔软。通过揉纹，既改善了表面纹路，又提高了合成革的柔软度，实现手感与花纹的综合提高。目前，在揉纹工艺中会使用柔软剂，包括表面活性剂类柔软剂和有机硅类柔软剂，以使基布呈现柔软舒适的手感。但所使用的柔软剂仅具有柔软作用，不会促进树脂膜表面花纹凹凸感的清晰化，且有机硅类柔软剂的水溶性差，不利于制成水性添加液。
发明内容：
本发明所要解决的技术问题在于提供一种利于清晰花纹、提高真皮逼真感、增强手感的适用于合成革的水性揉纹助剂。
本发明所要解决的技术问题采用以下的技术方案来实现：
一种适用于合成革的水性揉纹助剂，由如下重量份数的原料制成：
预胶化淀粉10-15份、纳米二氧化钛改性泊洛沙姆5-10份、聚环氧乙烷2-3份、羟乙基纤维素2-3份、冷溶型聚乙烯醇2-3份、活性白土1-2份、纳米滑石粉1-2份、米糠蜡0.5-1份、纳米陶瓷胶粉0.5-1份、聚合氯化铝0.3-0.5份、聚天门冬氨酸0.1-0.3份、氯化十六烷基吡啶0.05-0.1份、水100-150份。
其制备方法包括如下步骤：
(1)向聚环氧乙烷中加入冷溶型聚乙烯醇、纳米陶瓷胶粉和聚合氯化铝，并以5℃/min的升温速度升温至75-80℃保温混合15-30min，再继续以5℃/min的升温速度升温至115-120℃保温混合15-30min，然后自然冷却至室温，即得物料I；
(2)向水中加入纳米二氧化钛改性泊洛沙姆和聚天门冬氨酸，搅拌溶解完全后静置15-30min，再加入米糠蜡和氯化十六烷基吡啶，并以5℃/min的升温速度升温至回流状态保温混合10-15min，然后自然冷却至室温，即得物料II；
(3)向物料II中加入预胶化淀粉、活性白土和纳米滑石粉，充分混合后于微波频率2450MHz、输出功率700W下微波处理3-5min，再加入物料I和羟乙基纤维素，混合均匀后继续微波处理3-5min，所得混合液经自然冷却至室温后送入球磨机中，研磨5-8h后过300目筛，所得滤液即为水性揉纹助剂。
所述纳米二氧化钛改性泊洛沙姆由泊洛沙姆经纳米二氧化钛并辅以助剂改性而成，其制备方法为：将泊洛沙姆以5℃/min的升温速度升温至75-80℃保温研磨5-10min，再加入纳米二氧化钛、阴离子聚丙烯酰胺和聚二甲基二烯丙基氯化铵，继续以5℃/min的升温速度升温至120-125℃保温研磨15-30min，并以5℃/min的降温速度降温至0-5℃保温静置2-3h，然后加入氢化蓖麻油和聚乙烯醇缩丁醛，再次以5℃/min的升温速度升温至120-125℃保温研磨15-30min，待自然冷却至45-50℃后向所得混合物中加入70-75℃热水，搅拌使混合物充分溶解，过筛除去不溶物，所得滤液送入喷雾干燥机中，干燥所得颗粒经超微粉碎机制成微粉，即得纳米二氧化钛改性泊洛沙姆。
所述泊洛沙姆、纳米二氧化钛、阴离子聚丙烯酰胺、聚二甲基二烯丙基氯化铵、氢化蓖麻油、聚乙烯醇缩丁醛和热水的质量比为15-20:3-5:0.5-1:0.3-0.5:0.1-0.2:0.05-0.1:50-80。
泊洛沙姆经上述改性处理后，在增强其表面活性的同时显著减少其溶于水后产生的泡沫。
所述纳米陶瓷胶粉由如下重量份数的原料制成：陶瓷微粉3-5份、氢化松香季戊四醇酯2-3份、烯丙基缩水甘油醚2-3份、六羟甲基三聚氰胺六甲醚1-2份、C5加氢石油树脂1-2份、微晶蜡0.5-1份、松节油0.5-1份、马来酸酐接枝相容剂0.05-0.1份，其具体制备方法为：向氢化松香季戊四醇酯中加入烯丙基缩水甘油醚和C5加氢石油树脂，并以5℃/min的升温速度升温至115-120℃保温混合15-30min，再加入微晶蜡和马来酸酐接枝相容剂，继续在115-120℃保温混合15-30min，待以10℃/min的降温速度降温至50-60℃后加入陶瓷微粉、六羟甲基三聚氰胺六甲醚和松节油，充分混合，所得混合物转入-5-0℃环境中静置1-2h，最后送入纳米研磨机中，经充分研磨后制得粒径在30-50nm的纳米陶瓷胶粉。
本发明的有益效果是：本发明水性揉纹助剂以水作为溶剂，具有使用安全性高和保护环境的特点，将所制水性揉纹助剂加入合成革浸水水箱中，经浸水、轧压保持一定带液率后进行揉纹，该揉纹助剂能促进基布上的树脂膜在温度和机械力作用下发生收缩，使表面花纹的凹凸感更清晰；并且使树脂膜表面花纹产生类似真皮的无规则性，提高真皮逼真感；同时通过松散纤维使基布变得更加柔软，实现手感与花纹的综合提高。

纳米陶瓷胶粉的制备：向2份氢化松香季戊四醇酯中加入2份烯丙基缩水甘油醚和1份C5加氢石油树脂，并以5℃/min的升温速度升温至115-120℃保温混合30min，再加入0.5份微晶蜡和0.05份马来酸酐接枝相容剂，继续在115-120℃保温混合15min，待以10℃/min的降温速度降温至50-60℃后加入5份陶瓷微粉、1份六羟甲基三聚氰胺六甲醚和0.5份松节油，充分混合，所得混合物转入-5-0℃环境中静置2h，最后送入纳米研磨机中，经充分研磨后制得粒径在30-50nm的纳米陶瓷胶粉。
实施例3
将等量实施例1、实施例2、对照例1和对照例2所制水性揉纹助剂加入合成革浸水水箱中，并设置不使用水性揉纹助剂的对照例3，再经相同浸水、轧压和揉纹工艺处理，对处理后的合成革表面花纹状态和手感进行比较。
比较结果显示，经实施例1和实施例2所制水性揉纹助剂处理后的合成革表面花纹的凹凸感最清晰，同时表面花纹产生类似真皮的无规则性，效果更自然逼真，且手感柔软度适中；其次，依次减弱的是对照例1所制水性揉纹助剂、对照例2所制水性揉纹助剂；表面花纹状态和手感最差的是不使用水性揉纹助剂的对照例3。
以上显示和描述了本发明的基本原理和主要特征和本发明的优点。本行业的技术人员应该了解，本发明不受上述实施例的限制，上述实施例和说明书中描述的只是说明本发明的原理，在不脱离本发明精神和范围的前提下，本发明还会有各种变化和改进，这些变化和改进都落入要求保护的本发明范围内。本发明要求保护范围由所附的权利要求书及其等效物界定。
