Abstract
本发明公开了一种环保低温皂洗剂,按质量份计包括如下组分:马来酸酐‑丙烯酸‑乙氧基亚甲基丙二酸二乙酯三元共聚物溶液30‑50份,羧乙基硫代丁二酸10‑30份,乙二胺二邻羟苯基乙酸钠0.5‑5份,矿物粘土5‑10份,水30‑50份。本发明环保低温皂洗剂为灰色半透明液体,不含磷氮,环保高效,皂洗温度可到40‑60℃,作用于棉及其混纺织物活性染料染色及印花后皂洗防沾色能力强,去浮色效果显著,且应用于活性染料皂洗后皂洗废水COD值较低,降低后道污水处理成本,在硬水中性能稳定,具有明显的市场优势。
Description
一、技术领域
本发明涉及一种环保低温皂洗剂,用于纺织染整行业棉及其混纺织物活性染料染色及印花后皂洗处理工艺,属于精细化工领域。
二、背景技术
棉、麻、粘、天丝等纤维及其混纺织物染色和印花后必须经过皂洗,皂洗主要目的就是为了去除粘附在纤维上的水解染料、未固着的染料和其他杂质。传统市场上多采用一些含磷氮类及表面活性剂类皂洗剂,对环境造成严重富营养。
近年来国内出现了丙烯酸、马来酸酐等单体共聚合成的酸性皂洗剂,由于这种皂洗剂无泡沫,皂洗剂去浮色效果好且节约用水,从而得到了广泛的使用。
CN105199861A介绍了一种不含磷酸性皂洗剂,其中嵌段改性的马丙树脂溶液由马来酸或马来酸酐与丙烯酸、α,ω-双稀基封端聚醚合成的三元共聚高分子溶液,具有净洗效果强、螯合性高等特点。
CN10178163是将脂肪醇聚氧乙烯醚与丙烯酸等先发生单体聚合,然后与丙烯酸、马来酸酐等共聚制成改性单体,再与脂肪醇聚氧乙烯醚等其他表面活性剂复配而成,据称所制作皂洗剂,净洗及防沾色效果良好。可见,用新法合成新型结构改性马丙树脂可作为新型皂洗剂的重要原料。
由各种改性马丙树脂为基础,研究发现由乙氧基亚甲基丙二酸二乙酯(EMME)进行改性的马丙树脂,再与其他表面活性剂复配的皂洗剂组合物效果更优,且矿物粘土较强的吸附作用可应用于纺织品的去浮色,效果较明显,在各种文献中未见报道。
三、发明内容
本发明旨在提供一种环保低温皂洗剂,用于棉织物活性染料染色或印花后皂洗,不仅解决了磷盐皂洗剂对环境造成富营养化,生物降解性好,且在40-60℃即达到良好的皂洗效果,去浮色能力较强,皂洗后废水COD值较低,易于后道废水处理。
本发明环保低温皂洗剂,按质量份计包括如下组分:
马来酸酐(MAH)-丙烯酸(AA)-乙氧基亚甲基丙二酸二乙酯(EMME)三元共聚物溶液(下文简称三元共聚物溶液)30-50份,羧乙基硫代丁二酸10-30份,乙二胺二邻羟苯基乙酸钠0.5-5份,矿物粘土5-10份,水30-50份。
所述三元共聚物是由如下单体在水相经溶液共聚制得:
所述三元共聚物的制备过程如下:
将引发剂10kg置于混料桶中,加入90kg去离子水搅拌溶解,配制成10%的引发剂溶液;向反应釜中加入马来酸酐单体100kg,升温至30-40℃搅拌溶解,然后加入氢氧化钠水溶液调pH值至中性,加入引发剂溶液,向反应釜中缓慢加入丙烯酸150-400kg和乙氧基亚甲基丙二酸二乙酯60-80kg,在3-5小时加入完成,调节pH值为3-5,原料加入过程中控制反应温度保持在40℃以下,加料完成后在40℃以下搅拌反应20-30分钟,再缓慢升温至85℃,保持搅拌转速70-90r/min,密封反应4-6小时,反应结束后降至室温,得到三元共聚物溶液,其含固量为80-90%。
所述引发剂为过硫酸盐中的一种或几种,优选为过硫酸钠、过硫酸钾、过硫酸铵中的一种或几种。引发剂溶液的添加量为马来酸酐单体质量的5-6%。
所述矿物粘土为沸石、凹凸棒土、膨润土、硅藻土中的一种或几种。
本发明环保低温皂洗剂的制备过程如下:
在常温下将300-500kg三元共聚物溶液加入300-500kg去离子水中,搅拌均匀,依次加入羧乙基硫代丁二酸100-300kg、乙二胺二邻羟苯基乙酸钠5-50kg和矿物粘土50-100kg,经研磨分散得到灰色半透明液体。
与已有技术相比,本发明的有益效果体现在:
本发明通过加成乙氧基亚甲基丙二酸二乙酯(EMME)对传统马丙树脂进行改性,通过此法聚合而成的高分子聚合物溶液,具有较强的分散性及螯合性,且不含氮、磷等物质,通过羧乙基硫代丁二酸、乙二胺二邻羟苯基乙酸钠等的协同增效作用,应用于棉织物活性染料染色和印花后皂洗工艺,增强了皂洗剂的净洗性及去污性,使在较低温度40-60℃即达到良好的皂洗效果;矿物粘土的应用提高吸附能力,去浮色及防沾效果显著,且该发明成品应用于活性染料皂洗后皂洗废水COD值较低,降低后道污水处理成本,且在硬水中性能稳定,环保节能具有明显的市场优势。

对比不同皂洗温度下皂洗效果:按耐洗色牢度试验方法GB/T3921测试耐洗色牢度;按耐摩擦色牢度试验方法GB/T3920测试其皂洗效果;按照皂洗剂在硬水中稳定性的试验方法GB/T7381测试皂洗剂在硬水中稳定性;测试皂洗后脚水COD值。市售产品样1、市售产品样2与5NPF皂洗效果测试对比见表1、表2。
经实施例的系列测试说明,对比市售产品样1、市售产品样2与5NPF皂洗效果样品,本发明所述新型环保低温皂洗剂应用于棉及其混纺织物活性染料染色皂洗工艺,皂洗温度可低至40-60℃,去浮色及防沾效果显著,皂洗后摩擦牢度优,皂洗废水COD值较低,降低后道污水处理成本,本发明的皂洗剂性能稳定,耐硬水能力强,环保节能具有明显的市场优势。
