Antibiotic paper and its preparing process

Abstract

An antibacterial paper and a preparation process thereof are provided. The preparation process includes fully dissolving and diluting the water-soluble 2-Hydroxypropytrimethylammonium chloride chitosan in a distribution device to obtain the antibacterial liquid; clinging the antibacterial liquid to the wet paper web in a manner of impregnating, spraying or sizing at a proper part between the sizing and the coating of a tape unit; and conventionally drying. The preparation process is so simple that only the addition of a spraying device or a solution tank for impregnating is required. The inventive preparation has convenient processing and easy operation and the prepared antibacterial paper thereof has broad-spectrum antibacterial property, low cost and economic practicability.

Description

technical field [0001] The invention belongs to the field of antibacterial materials and papermaking, and in particular relates to an antibacterial paper and a preparation process thereof. Background technique [0002] In recent years, with the development of society and the improvement of people's living standards, people have paid more and more attention to the hygiene of working and living environments, which has promoted the research and development of materials with antibacterial functions. Various antibacterial products have gradually filled people's lives, such as antibacterial Plastics, antibacterial fabrics, etc. However, there are few reports about antibacterial paper. Antibacterial paper has a wide range of uses, and can be used for the packaging of leather products, food, medicine, and fruit, as well as the base paper for securities and bills in the manufacturing and circulation field. However, ordinary paper does not have antibacterial function. Paper contamin...

Problems solved by technology

However, ordinary paper does not have antibacterial function. Paper contaminated by bacteria is not only prone to mildew and affects its quality, but also can become a medium for the spread of many germs. Therefore, an antibacterial paper with antibacterial function came into being.

The common antibacterial paper is prepared by coating or spraying a drug layer on its surface, or by dipping. Its antibacterial effect will gradually fail during deep processing or with different storage time and storage temperature; another The common preparation method of antibacterial paper is to add antibacterial agent directly into the slurry, but the added antibacterial agent is easy to be lost with white water during the surfing process, resulting in a large amount of antibacterial agent, while the antibacterial component retained in the paper is very little , which not only increases the cost, but also fails to achieve good antibacterial effect
