Problems solved by technology

[0004] In this regard, people have carried out extensive research. At present, it is more common to add chemical antibacterial agents to the materials for making fresh-keeping boxes and form them together with fresh-keeping boxes. It will produce some toxic and irritating gases, and it is easy to migrate and precipitate when added to plastic packaging products, and even run into packaged food, fruits and vegetables, medical drugs, etc., causing unsafe use. These organic antibacterial agents are used in food Packaging and medical fields are generally not allowed to add

Abstract

The invention discloses a composite antibacterial cellulose preservation box and a preparation method thereof. An anti-bacterial component is extracted from wormwood, dahurian patrinia herb, all-grass of foxtail-like Sophora and clerodendrum cyrtophyllum, and a composite anti-bacterial material is prepared from the anti-bacterial component, a ferrous compound and other additives; besides, the materials is dissolved in agarose with a porous structure and is applied onto the surface of the preservation box. In a daily using process, on one hand, water is sucked by agarose, so that articles in the preservation box are kept dry; on the other hand, even if bacteria breed, the bacteria grow on the surface with agarose of the preservation box, and agarose contains bacteriostatic and bactericidal active substances in agarose, so that the bacteria in agarose can be killed. Therefore, an environment adverse to growth of the bacteria is created, and the purpose of sterilization can be achieved; in addition, the made preservation box is environment-friendly, safe, green and pollution-free; plant raw materials are from common plant raw materials, so that the cost is low, the manufacturing process is simple, and the application value is comparatively high.

Description

technical field [0001] The invention relates to an antibacterial fresh-keeping box, in particular to a composite antibacterial cellulose fresh-keeping box and a preparation method thereof. Background technique [0002] At present, with the increasing development of online shopping, more and more people choose to buy fresh products online. However, due to changes in the climate and environment during transportation, the products may deteriorate, especially some fresh fruits and vegetables, which need to invest a lot of resources. Antibacterial and fresh-keeping storage and transportation of it will virtually increase costs, reduce profits, and more importantly, waste a lot of extra resources. Similarly, high-end cosmetics and precious biological specimens contain biological factors, which are extremely vulnerable to microorganisms, resulting in irreparable losses. [0003] With the development of science and technology and the improvement of people's living standards, people...
