Description

一种防霉抗菌性合成革浆料及其制备方法
技术领域
本发明涉及一种人造革用浆料，具体涉及一种防霉抗菌性合成革浆料及其制备方法。
背景技术
聚氨酯合成革具有光泽柔和、自然，手感柔软，真皮感强，耐挠曲、抗老化等优异的特点，是天然皮革的最为理想的替代品，广泛应用于服装、制鞋、箱包、家具等行业；但是目前市场上的聚氨酯合成革在透湿性、耐磨性方面与天然皮革差距太大，透湿性能差的聚氨酯合成革制品会令人感觉闷热、湿冷，针对这些缺点，目前主要通过改变聚氨酯合成革浆料的性能进行改善，但目前市场上改变聚氨酯合成革浆料透湿性和耐磨性的工艺较复杂，成本较高，效果也不太明显。
发明内容
本发明的目的在于提供一种防霉抗菌性合成革浆料及其制备方法。
本发明采用如下技术方案：
防霉抗菌性合成革浆料，其组成原料的重量份为：PVC树脂粉65-70、热塑性聚氨酯弹性体橡胶30-35、2-正辛基-4- 异噻唑啉-3- 酮2.0-2.5、三聚氰胺甲醛树脂3.5-4.5、二甲基硅油1-3、硬脂酸单甘酯0.4-0.5、玉米纤维0.5-0.7、落花生叶4-7、氧化铝粉末28-30、正硅酸乙酯5-8和二甲基甲酰胺65-70。
防霉抗菌性合成革浆料，其组成原料的重量份为：PVC树脂粉68、热塑性聚氨酯弹性体橡胶32、2-正辛基-4- 异噻唑啉-3- 酮2.2、三聚氰胺甲醛树脂4、二甲基硅油2、硬脂酸单甘酯0.45、玉米纤维0.6、落花生叶5、氧化铝粉末29、正硅酸乙酯6.5和二甲基甲酰胺68。
防霉抗菌性合成革浆料的制备方法，包括以下步骤：
（1）落花生叶的改性处理：按组成原料的重量份称取落花生叶，将落花生叶粉碎、烘干，加入少许水和适量的双氧水，浸泡30-40分钟后用0.1mol/L的碳酸氢钠溶液将pH值调节至7-8，再加入落花生叶质量的3-4%纳米二氧化硅和2-4%明胶，在50-80℃温度下搅拌反应1-4小时，再经过抽滤、洗涤后于105-110℃烘箱中烘干4-5小时，即得改性落花生叶，备用；
（2）将氧化铝粉末送入煅烧炉中在500-550℃下煅烧2-3小时，取出冷却后研磨成80-200目粉体；备用；
（3）按重量份称取配方中的所有原料，先将二甲基甲酰胺放入反应釜中，通入蒸汽，升温至80-100℃范围内；然后依次加入PVC树脂粉、热塑性聚氨酯弹性体橡胶、2-正辛基-4- 异噻唑啉-3- 酮和三聚氰胺甲醛树脂；继续保温反应2-3小时后，再调节pH值为6-7之间；加入其它组成原料，搅拌均匀，降温到室温，过滤，出料。
将制得的合成革浆料以 150-180g/m2的刮涂量涂于离型纸表面，经烘干、上糊后再用合成革基布一起贴合，在 100-120℃条件下烘干5-6 分钟，然后在80-100℃条件下固化18-20小时即可。
本发明的有益效果：
本发明的的合成革浆料具有质轻、耐磨等优点，且原料取得容易，原料中混入抗菌物质，使得浆料具有抗菌、防霉、除虫等优点，而且本发明通过对落花生叶的改性，可以提高落花生叶的粘性，增强浆料的粘稠性，提高浆料的性能稳定。
