Description
技术领域
本发明属于合成革生产领域，具体涉及一种舒适度高的PU合成革及其生产方法。
背景技术
PU合成革属于聚氨酯弹性体，从结构上近似天然皮革，且具备外观质感良好、机械性能强、价格低廉、加工方便等优势，其应用范围广、种类数量繁多，是代替天然皮革较为理想的材料，目前已大量取代资源不足的天然皮革。然而PU合成革的部分性能远不如天然皮革，如天然皮革具有良好的吸水性、透气性，而PU合成革本身的性质导致其容易形成致密的膜，吸水、透气性能受到限制，合成革的仿真性、舒适度和品质难以提高。
发明内容
本发明的目的在于提供一种仿真性高、防霉抗菌、抗氧化、杀虫驱虫的舒适度高的PU合成革及其生产方法。
上述目的通过以下技术方案实现：
一种舒适度高的PU合成革，包括基布层和PU层，其中：
PU层由下述重量份的原料制得：
聚氨酯树脂80-100，二甲基甲酰胺80-100，茶皂素2-4，可溶性大豆多糖0.5-1，液体松香树脂1-2，角鲨烷0.1-0.2，滑石粉1-2，竹炭粉1-2，色浆4-8，羧甲基纤维素钠5-10，水杨酸钠0.2-0.4，氯化铝0.5-1，改性助剂2-4；
其中改性助剂由下列重量份的原料制成：
高岭土30-40，海泡石10-15，石棉纤维15-20，苎麻纤维5-10，碳酸钙2-4，氯化钙1-3，棕榈油2-4，硬脂酸镁2-4，生育酚0.2-0.5，三聚磷酸钠4-6，磺化琥珀酸二辛酯钠盐1-2，葡萄糖酸钙1-2；
改性助剂的制备方法是：
将高岭土、海泡石、石棉纤维粗研磨后加入三聚磷酸钠、碳酸钙和氯化钙混合均匀，550-600℃煅烧4-6h，降温至150-200℃后加入硬脂酸镁和苎麻纤维搅拌1-2h，冷却后研磨至400-500目，加入其余原料60-80℃搅拌1-2h，即得。
一种舒适度高的PU合成革的生产方法，包括以下步骤：
（1）将氯化铝和可溶性大豆多糖加入适量水中，800-1000r/min搅拌15-30min，加入羧甲基纤维素钠和水杨酸钠，600-800r/min搅拌5-10min，冷冻干燥后研磨至100-200目，得活性粉体；
（2）在容器中先加入二甲基甲酰胺，再加入滑石粉、竹炭粉、液体松香树脂、茶皂素、活性粉体和改性助剂，于25-40℃下充分搅拌10-20min后加入色浆和聚氨酯树脂，搅拌均匀后加入其余原料，800-1000r/min搅拌5-10min，真空脱泡30-60min，50-100目过滤，得PU浆料；
（3）将基布浸湿，采用涂刀涂覆法把PU浆料均匀地涂覆在基布上，送入凝固槽凝固，再经过水洗、烘干，经表面处理后，即得成品。
本发明的优点是：
1. 结合水凝胶技术，发挥其优越的吸水性作用，使产品具有良好的吸水透气性能和仿真的外观、手感，有效提高了PU合成革的舒适度以及仿真性，合成革的性能更接近天然皮革；
2. 添加天然非离子表面活性剂茶皂素，改善了合成革的品质和抗老化性能，还具有防霉抗菌、抗氧化、杀虫驱虫的辅助作用。
以下通过实施例形式的具体实施方式，对本发明的上述内容再作进一步的详细说明，但不应理解为本发明上述主题的范围仅限于以下的实施例，凡基于本发明上述内容所实现的技术均属于本发明的范围。
具体实施方式
下面结合具体实施例对本发明一种舒适度高的PU合成革及其生产方法作进一行说明：
