Description

一种匀染性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，具体的说是一种匀染性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，本发明提出一种匀染性合成革浆料及其制备方法。
一种匀染性合成革浆料，其组分及各组分的质量份数为：聚氯乙烯树脂90-115份、炭黑粉6-7份、硬脂酸3-4份、对(N-甲氧基甲酰胺基)苯磺酰肼3-5份、壬基酚聚氧乙烯醚2.5-3.5份、唐菖蒲叶10-15份、二异氰酸酯18-23份、硫磺0.5-0.8份、甲基三乙氧基硅烷5-7份。
所述各组分的最佳质量份数为：聚氯乙烯树脂110份、炭黑粉6份、硬脂酸3份、对(N-甲氧基甲酰胺基)苯磺酰肼4份、壬基酚聚氧乙烯醚3份、唐菖蒲叶13份、二异氰酸酯21份、硫磺0.7份、甲基三乙氧基硅烷6份。
一种匀染性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40-50分钟，降至常温，然后将上述混合液过滤，备用；
(2)将甲基三乙氧基硅烷、二异氰酸酯、壬基酚聚氧乙烯醚充分混合，在混合过程中逐步加入硫磺，以4000-5000转/分钟搅拌25-35分钟之后，在120-140KPa反应釜中反应40-50分钟，然后降至60-80℃保温15-20分钟，备用；
(3)将聚氯乙烯树脂、硬脂酸和对(N-甲氧基甲酰胺基)苯磺酰肼在80-100℃条件下充分搅拌混合，混合过程中加入炭黑粉，然后在反应釜中反应50-60分钟，之后加入步骤(1)与步骤(2)中备用溶液，之后充分搅拌30-40分钟，静置反应10-15分钟，采用真空去泡处理，即制得最终合成革浆料。
本发明的有益效果是：
本发明采用了聚氯乙烯树脂作为主要成分，并使用炭黑粉作为辅助剂，炭黑是一种无定形碳。轻、松而极细的黑色粉末，表面积非常大，范围从10-3000m2/g，因此能够极大地提高合成革成品中微孔总量，在浆料中加入燃料之后，能够更加充分和均匀的借助微孔牢固分布在浆料中，成品合成革颜色更加鲜艳，颜料更加均匀，也降低了搅拌加工劳动量，提高了劳动效率；植物纤维结构成分在增强合成革结合强度的同时，也能起到吸附颜料的作用，与炭黑共同作用，使燃料均匀与浆料融合。
