Description

一种防腐增效剂、制备方法及其应用
技术领域
本发明涉及工业防腐领域，尤其是涉及的是一种含有支链非离子型表面活性剂与季铵盐类表面活性剂的防腐增效剂、制备方法及其应用。
背景技术
近年来，研究者对于食品、化妆品、饲料、水性涂料和水性粘合剂等行业的霉腐微生物区域分布及其控制技术进行了广泛的调查和研究，陆续发现不少杀菌剂在连续使用若干年后菌群的抗药性已发生，杀菌防腐效果逐步下降。有些工厂为了减少霉腐微生物的危害，盲目加大杀菌剂的使用，不仅无法达到更有效的防腐作用，而且为人类生存环境和自然生态平衡造成很大的污染和破坏。
中国专利CN104365668A公开了一种环保长效复合防污材料：重量百分比银5-70wt％，铜5-30wt％，异噻唑啉酮类化合物20-80wt％，金属吡啶硫酮类化合物5-50wt％。异噻唑啉酮类化合物即一种抗菌剂的高剂量使用，不仅可能引发安全性问题，且易产生抗药性。因此，高效、安全、稳定，对于防腐性能起增效作用的防腐添加剂的研制具有了较大的应用价值和发展前景。
发明内容
本发明的目的在于克服上述不足，提供一种含有支链非离子型表面活性剂与季铵盐类的防腐增效剂。
为实现上述目的，本发明的技术解决方案是：一种防腐增效剂，含有支链非离子型表面活性剂14～35wt％、季铵盐类表面活性剂2.8～7wt％、茶多酚1～3wt％、氯化钾1～3wt％、甲基丙二醇30～50wt％，去离子水余量。
优选的，所述的支链非离子表面活性剂为三硬脂山梨坦、蔗糖脂肪酸酯、甲基葡糖苷衍生物中的一种或多种。
优选的，所述的蔗糖脂肪酸酯为蔗糖乙酸异丁酸酯、蔗糖八乙酸酯、蔗糖苯甲酸酯、蔗糖硬脂酸酯中的一种或多种。
优选的，所述的甲基葡糖苷衍生物为甲基葡萄糖聚氧乙烯醚、甲基葡萄糖二油酸酯、甲基葡萄糖倍半硬脂酸酯、甲基葡萄糖聚氧乙烯醚苯甲酸酯、香豆酸葡萄糖苷、癸基吡喃葡萄糖苷、山奈酚葡萄糖苷、苔黑酚葡萄糖苷中的一种或多种。
优选的，所述的季铵盐类表面活性剂为十二烷基氯化吡啶、十四烷基氯化吡啶、十六烷基氯化吡啶、十烷基三甲基溴化铵、十二烷基三甲基溴化铵、十四烷基三甲基溴化铵、十八烷基溴化铵中的一种或多种。本发明还包括防腐增效剂的制备方法，将上述配方量的去离子水、支链非离子型表面活性剂、季铵盐类表面活性剂、茶多酚、氯化钾、甲基丙二醇投入气流混合机中，压缩空气操作压力0.8Mpa，经3-5分钟混合均匀制得。
本发明还包括一种添加上述防腐增效剂的防腐剂，其中：所述防腐增效剂占该防腐剂的1～60wt％，余量为日用卫生品上可接受的抗菌剂、助剂和载体。
优选的，所述抗菌剂为聚六亚甲基胍、咪唑烷基脲、异噻唑啉酮类、尼泊金酯类中的一种或多种。
优选的，所述防腐增效剂与抗菌剂的重量比为1～10：1。
本发明还包括所述的防腐剂在洗涤产品防腐和涂料防腐领域中的应用。
通过采用上述的技术方案，本发明的有益效果是：利用支链非离子型表面活性剂作为防腐载体，包覆抗菌分子，降低抗菌分子受到的细胞膜静电排斥，同时季铵盐类表面活性剂改变菌体细胞膜的通透性，协同作用下提高抗菌分子的杀菌抑菌效率，在减少抗菌组分添加量同时保持原有甚至更佳的防腐效果。对于防腐体系降低毒性、环保安全和成本控制具有重大作用。
