便携式免洗织物去污喷剂的研制

Study on portable unwashed decontamination spray for fabric

选择非离子表面活性剂脂肪醇聚氧乙烯醚(AEO9)与3种常用的阴离子表面活性剂(十二烷基醚硫酸钠(AES)、直链烷基苯磺酸钠(LAS)和十二烷基硫酸钠(K12))进行复配,制备以表面活性剂和过氧化氢为主要去污成分的去渍液,研究表面活性剂种类、用量和双氧水用量对去渍液去污效果的影响,考察其稳定性,并从去污力和是否引起有色织物褪色两个方面与市场同类热销产品贝克曼去污笔进行对比,结果表明:去渍液的最佳配方为30%(若无特指,百分数均为质量分数)双氧水(6. 0%),K12(0. 468 3%),AEO9(0. 041 7%),95%乙醇(9. 0%),EDTA二钠(1. 5%),香精(适量),柠檬酸(适量)和去离子水(加至100%);按照该配方制备的去渍液放置1周后,其去污效果无明显变化,且始终为无色透明溶液,无分层现象,稳定性良好;所制的去污喷剂去除橙汁和咖啡汁液的能力比贝克曼去污笔稍强,而去除番茄汁和菜汁的能力稍弱,用于有色织物去污时不会导致织物明显褪色,而贝克曼去污笔则会导致织物明显褪色.

The nonionic surfactant fatty alcohol polyoxyethylene ether( AEO9) was selected with the compound of three commonly used anionic surfactants( sodium lauryl ether sulfate( AES),sodium linear alkylbenzene sulfonate( LAS) and sodium dodecyl sulfate( K12) to prepare a de-staining liquid with surfactant and hydrogen peroxide as main decontaminating ingredients. The effect of surfactant type,dosage and hydrogen peroxide dosage on decontamination of de-staining liquid was studied,and its stability was investigated. Compared with similar hot products in the market from two aspects of the detergency and whether it caused the fading of colored fabrics,the results showed that: the best formula for de-staining liquid was 30%( If there was no specific reference,it refered to the quality score.),hydrogen peroxide( 6. 0%),K12( 0. 468 3%),AEO9( 0. 041 7%),95% ethanol( 9. 0%),disodium EDTA( 1. 5%),flavor( appropriate amount),citric acid( appropriate amount) and deionized water( added to 100%);The de-staining solution prepared according to the formula was left for 1 week,the decontamination effect did not change significantly,and it was always a colorless and transparent solution with no delamination and good stability. The ability of the decontamination spray to remove orange juice and coffee was slightly stronger that of Beckman decontamination pen,the ability to remove tomato juice and vegetable juice was slightly weaker,when it was used to the fabric color decontamination. It would not cause more obvious fading,but Beckman decontamination pen would cause more obvious fading.
