Abstract

本发明涉及一种高结合强度合成革浆料及其制备方法，合成革浆料组分及各组分的质量份数为：聚氯乙烯30‑34份、磷酸三正丁酯7‑10份、氢氟酸8‑12份、水镁石粉4‑7份、环氧乙烷1.5‑1.8份、唐菖蒲叶10‑15份、四氢呋喃18‑23份、三乙胺4‑6份、甲基三乙氧基硅烷3‑5份。本发明中，由于水镁石粉的粉体在进行超细粉碎后,比表面积增大,表面能升高，所以颗粒极易团聚，在与四氢呋喃、甲基三乙氧基硅烷混合过程中，能够增强浆料的粘稠性和粘连性，大大提高合成革的抗拉强度。

Description

一种高结合强度合成革浆料及其制备方法
技术领域
本发明涉及人造革用浆料技术领域，具体的说是一种高结合强度合成革浆料及其制备方法。
背景技术
然而随着世界人口的增长，人类对皮革的总量和种类需求均倍增，数量有限的天然皮革早已不能满足人们这种需求。于是科学家们开始研制合成革。
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。在合成革的生产制作过程中，通常以经浸渍的无纺布为网状层，微孔聚氨脂层作为粒面层制得。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。
然而现有合成革普遍存在以下缺点：1、通常只能采用沾水用洗涤剂清洗的方式清洗，不能采用汽油彻底清除污渍，且不能采用干洗。2、水洗时候，水温不能超过40℃，然而低温水洗清洗效果不佳，不能发挥洗涤剂的最佳性能。3、不能暴晒，因此合成革易老化、耐候性差，在世界上的高温地区使用效果不佳。4、由于合成革的自身性能，绝大多数合成革不能接触有机溶剂，容易被腐蚀。5、合成革不耐折叠，折叠过后会产生折痕和开裂，尤其在潮湿环境下。6、合成革在潮湿环境下极易伸张并开始发霉，因此储存条件要求苛刻。
鉴于以上缺点限制了合成革的广泛使用，因此人们需要更多种类的特种合成革，从而有针对性的提高合成革在不同条件下的使用要求。
发明内容
为了实现上述目的，提高皮革离型纸的连接强度，本发明提出一种高结合强度合成革浆料及其制备方法。
一种高结合强度合成革浆料，其组分及各组分的质量份数为：聚氯乙烯30-34份、磷酸三正丁酯7-10份、氢氟酸8-12份、水镁石粉4-7份、环氧乙烷1.5-1.8份、唐菖蒲叶10-15份、四氢呋喃18-23份、三乙胺4-6份、甲基三乙氧基硅烷3-5份。
所述各组分的最佳质量份数为：聚氯乙烯32份、磷酸三正丁酯8份、氢氟酸11份、水镁石粉5份、环氧乙烷1.6份、唐菖蒲13份、四氢呋喃22份、三乙胺5份、甲基三乙氧基硅烷4份。
一种高结合强度合成革浆料的制备方法，包括以下步骤：
(1)制取唐菖蒲叶改性溶剂：将全部的干燥的唐菖蒲叶粉碎，加入适量0.1mol/L盐酸，搅拌均匀，静止25-35分钟，盐酸添加量以完全浸没唐菖蒲叶为准，之后向上述混合液中加入适量一水合氨，将混合液调制至PH为8-9；然后将氢氟酸与调至中性后的溶液混合充分混合搅拌，搅拌之后在70-75℃环境下静置40-60分钟，降至常温，备用；
(2)将四氢呋喃、甲基三乙氧基硅烷混合，在混合过程中逐步加入水镁石粉，搅拌10-15分钟之后，将三乙胺与上述混合液，继续搅拌5-8分钟之后过滤，并在40-50℃环境下静置备用；
(3)将聚氯乙烯和磷酸三正丁酯在60-70℃条件下充分搅拌混合，并在120-140KPa压力下静置10-15分钟，之后加入步骤(1)与步骤(2)中备用溶液，同时加入环氧乙烷，充分搅拌至溶液均质，最后采用真空去泡的方式处理，即制得最终合成革浆料。
本发明的有益效果是：
本发明中，由于水镁石粉的粉体在进行超细粉碎后,比表面积增大,表面能升高，所以颗粒极易团聚，在与四氢呋喃、甲基三乙氧基硅烷混合过程中，能够增强浆料的粘稠性和粘连性，大大提高合成革的抗拉强度。
