Description
技术领域
本发明涉及聚乙烯面料技术领域,具体为一种高色牢度耐水洗的聚乙烯面料及其制备工艺。
背景技术
聚乙烯面料具有强度高、密度低、绝缘性佳等优点,主要用于生产各种工业用纺织品,用途广泛。
聚乙烯因价格较低,是最常用的塑料聚合物,具有稳定的化学性质、耐光性差。市面上常见的聚乙烯面料耐水洗色牢度差,经过多次水洗,会发生褪色的现象,使用时间过长,易老化,发生电荷堆积,不耐静电,且舒适性也欠佳,因此发明一种高色牢度耐水洗的聚乙烯面料尤为重要。
发明内容
本发明的目的在于提供一种高色牢度耐水洗的聚乙烯面料及其制备工艺,以解决上述背景技术中提出的问题。
为了解决上述技术问题,本发明提供如下技术方案:
所述制备工艺包括以下步骤:
S1:染料的制备:将染色剂、[2-羟基-4-(辛氧基)苯基]苯基酮、固色剂和一半的水混合均匀,砂磨20-30min,加入至剩余水中,搅拌均匀,升温至40-60℃,加入聚乙二醇,搅拌0.5-1h;
S2:聚乙烯织物的制备:在超高分子量聚乙烯中加入烷基磺酸钠、2,6-三级丁基-4-甲基苯酚、氢氧化镁,混合均匀,形成纤维,进行织造;
S3:聚乙烯基础面料的制备:将聚乙烯织物浸泡于盐酸多巴胺混合溶液中,再用染料进行染色;
S4:聚乙烯膜的制备:取超高分子量聚乙烯树脂,加热成熔融状,双向拉伸;
S5:聚乙烯面料的制备:将聚乙烯基础面料置于辊轧机上,表面覆上粘结剂胶膜,然后覆盖聚乙烯膜,设置工作温度为100-135℃,辊轧。
作为优化,所述S1步骤中的染料所需材料包括,以重量计:水30-50份、染色剂5-15份、[2-羟基-4-(辛氧基)苯基]苯基酮10-15份、固色剂10-15份、聚乙二醇2-8份。
作为优化,所述固色剂制备工艺为:
A:在水中加入氯化铵,混合均匀,使用氮气保护,升温至70-90℃;
B:加入二乙烯三胺,调节pH至9-10;
C:加入双氰胺,混合均匀,升温至130-150℃,反应40-50min,降温至80-100℃,加水,用冰醋酸调节pH至6.5-7,即得固色剂。
面料经过多次洗涤,会出现染料迁移和褪色的问题,加入固色剂提高染料的固色能力,而且提高了面料的耐水洗色牢度和耐碱汗色牢度,此外,又加入了[2-羟基-4-(辛氧基)苯基]苯基酮作为光稳定剂,提高了上染率,也增强了耐光色牢度,使面料具有高色牢度。
作为优化,所述固色剂所需材料包括,以重量计:水60-80份、氯化铵10-35份、二乙烯三胺10-20份、双氰胺20-30份、冰醋酸20-30份。
作为优化,所述S3步骤中聚乙烯基础面料制备工艺为:
A:盐酸调节三羟甲基氨基甲烷水溶液pH至8-9,加入盐酸多巴胺和聚乙烯亚胺混合均匀;
B:将聚乙烯织物浸泡10-12h,反复洗涤,干燥后于无水硫酸铜水溶液中搅拌1-2h,洗涤,干燥;
C:干燥后浸泡于染料中,100-110℃浸泡1-2h,染色结束后,即得聚乙烯基础面料。
使用盐酸多巴胺在织物表面形成牢固涂覆层,对超高分子量聚乙烯织物进行接枝改性,提高面料的抗菌性,再将铜固定在织物表面,是聚乙烯面料舒适性提升。
超高分子量聚乙烯具有优异的耐化学性,染色难度大,在100-110℃下浸泡1-2h染色,颜色深度有所提升,提高其上染率,染料中因具有固色剂和光稳定剂,使得颜料与面料的附着力强,且耐摩擦色牢度、耐洗色牢度均有所提升。
作为优化,所述聚乙烯织物所需材料包括,以重量计:超高分子量聚乙烯30-50份、烷基磺酸钠0.5-2份、2,6-三级丁基-4-甲基苯酚0.2-0.5份、氢氧化镁0.2-0.5份。
作为优化,所述聚乙烯基础面料所需材料包括,以重量计:聚乙烯织物15-30份、染料1-10份、盐酸0.5-1份、三羟甲基氨基甲烷0.5-1份、盐酸多巴胺0.1-0.4份、聚乙烯亚胺0.2-0.5份、无水硫酸铜1-3份。
作为优化,所述粘结剂胶膜制备工艺为:
A:将聚碳酸酯二醇100-120℃真空脱水1-2h,加入异佛尔酮二异氰酸酯、1-4丁二醇、有机铋催化剂,混合均匀,通氮气保护,70-90℃下反应1-2h;
B:加入2,2-二羟甲基丙酸继续反应1-2h,降温至40-50℃,加入甲基丙烯酸甲酯、丙烯酸丁酯、三乙胺后反应15-30min,加入水混合均匀,升温至70-90℃;
C:加入偶氮二异丁腈,反应3-5h,减压蒸馏,冷却后铺在聚四氟乙烯模板上,成膜2-3h,烘箱内脱模即得粘结剂胶膜。
丙烯酸树脂在粘结过程中耐候性差,易出现褪色、变色的现象,采用丙烯酸树脂对聚氨酯进行改性,制成了聚氨酯-丙烯酸树脂复合胶粘剂,提高了聚乙烯基础面料和聚乙烯膜的粘结性、耐候性、耐水洗色牢度,制成的聚乙烯面料柔软亲肤。
作为优化,所述粘结剂胶膜所需材料包括,以重量计:聚碳酸酯二醇20-30份、异佛尔酮二异氰酸酯25-30份、1-4丁二醇2-6份、有机铋1-5份、2,2-二羟甲基丙酸1-5份、甲基丙烯酸甲酯5-20份、丙烯酸丁酯5-15份、三乙胺2-5份、水20-40份、偶氮二异丁腈5-10份。
作为优化,根据以上所述的一种高色牢度耐水洗的聚乙烯面料的制备工艺制备的聚乙烯面料。
与现有技术相比,本发明所达到的有益效果是:本发明制成的聚乙烯面料具有高色牢度,采用超高分子量聚乙烯,加入烷基磺酸钠、2,6-三级丁基-4-甲基苯酚、氢氧化镁,使聚乙烯面料具有防静电、耐老化、阻燃的优点,使用高温常压进行染色,使燃料可以渗透至面料内部,增强上染率,染料中加入固色剂以及光稳定剂使聚乙烯面料具有耐水洗色牢度、耐光色牢度,对超高分子量聚乙烯织物进行表面接枝,提高了面料的抑菌性,穿着舒适,采用聚氨酯-丙烯酸树脂作为胶粘剂,减少了胶膜易发黏的缺陷,提高了面料的耐水洗色牢度。
