Description
技术领域technical field
本发明属于生活用品技术领域，尤其涉及一种抗菌消毒薄页纸的制备方法。The invention belongs to the technical field of daily necessities, and in particular relates to a preparation method of antibacterial and disinfecting tissue paper.
背景技术Background technique
随着社会发展和人民生活水平的提高，人们越来越重视自身健康，对生活环境的要求也不断提高。然而，近年来大规模爆发的由致病性微生物传播引起的传染病，如韩国的中东呼吸综合征(MERS)、非洲的埃博拉出血热、东南亚的禽流感、亚洲的SARS、德国的EHEC耐抗生素细菌导致的急性肠道疾病等，严重威胁着人体健康，造成了重大的经济损失。因此，具有抗菌抗病毒功能的各种材料应运而生，特别是与人们生活密切相关的具有抗菌抗病毒性能的生活用品的研究与开发日益受到重视。作为人们时时处处都会用到面巾纸、卷筒纸、厨房用纸等生活用薄页纸，由于人们生活的依赖性而成为致病微生物的重要传播途径。例如，一个感冒患者用面巾纸捂口打喷嚏或擦拭鼻涕后，将面巾纸随手扔进垃圾箱，此时面巾纸上沾染的感冒病菌和病毒借由空气将会得到广泛的传播。而这只是面巾纸会成为致病微生物传播途径的一小方面，实际上人们生活中的各类用纸是多种致病细菌和病毒的重要传播途径。因此，抗菌抗病毒功能生活用纸的开发与应用具有十分重要的意义。目前抗菌薄页纸主要是通过内部或表面施胶、表面涂布或喷洒抗菌剂的方法进行生产的。所用的抗菌剂主要为无机抗菌性金属离子如银、铜、锌等，以及有机抗菌剂如有机酸、季铵盐、酚醛类等。无机抗菌剂具有安全性、耐热性，但价格较高，且易使纸张变色；而有机抗菌剂杀菌力强、来源广泛，但有一定的挥发性且易析出。通过物理添加抗菌剂的方式生产的抗菌纸张，在储存和使用过程中由于抗菌剂的溶出，容易导致其抗菌性能的下降。并且小分子抗菌剂易在人体皮肤表面富集，具有一定的刺激性和毒性。另外，抗菌剂的流失还会造成环境污染。With the development of society and the improvement of people's living standards, people pay more and more attention to their own health, and their requirements for living environment are also constantly improving. However, in recent years, large-scale outbreaks of infectious diseases caused by the transmission of pathogenic microorganisms, such as Middle East Respiratory Syndrome (MERS) in South Korea, Ebola hemorrhagic fever in Africa, bird flu in Southeast Asia, SARS in Asia, EHEC in Germany, etc. Acute intestinal diseases caused by antibiotic-resistant bacteria have seriously threatened human health and caused major economic losses. Therefore, various materials with antibacterial and antiviral functions have emerged at the historic moment, and the research and development of daily necessities with antibacterial and antiviral properties, which are closely related to people's lives, have been paid more and more attention. As people always use facial tissue, roll paper, kitchen paper and other household tissue papers everywhere, they have become an important transmission route for pathogenic microorganisms due to the dependence of people's lives. For example, a patient with a cold covers his mouth with tissue paper to sneeze or wipe his nose, and then throws the tissue paper into the dustbin. At this time, the cold germs and viruses contaminated on the tissue paper will be widely spread through the air. And this is only a small aspect of facial tissue as a transmission route for pathogenic microorganisms. In fact, various types of paper in people's lives are important transmission routes for various pathogenic bacteria and viruses. Therefore, the development and application of antibacterial and antiviral functional household paper is of great significance. At present, antibacterial tissue paper is mainly produced by internal or surface sizing, surface coating or spraying antibacterial agents. The antibacterial agents used are mainly inorganic antibacterial metal ions such as silver, copper, zinc, etc., and organic antibacterial agents such as organic acids, quaternary ammonium salts, phenolic aldehydes, etc. Inorganic antibacterial agents are safe and heat-resistant, but they are expensive and easy to discolor paper; while organic antibacterial agents have strong bactericidal power and a wide range of sources, but they are volatile and easy to precipitate. The antibacterial paper produced by physically adding antibacterial agents is prone to decline in its antibacterial performance due to the dissolution of antibacterial agents during storage and use. Moreover, small molecule antibacterial agents are easy to accumulate on the surface of human skin, which has certain irritation and toxicity. In addition, the loss of antibacterial agents can also cause environmental pollution.
现有的抗菌薄页纸存在价格较高、易使纸张变色、抗菌性能不高，具有刺激性和毒性，容易造成环境污染。The existing antibacterial tissue paper has the advantages of high price, easy discoloration of paper, low antibacterial performance, irritation and toxicity, and easy environmental pollution.
