[0024] Preparation of silver-loaded zeolite

[0025] Use 4A artificial zeolite, add dilute nitric acid dropwise at 25°C, adjust the pH value to 5.5-6.5, heat in a water bath, stir and add the AgNO3 solution prepared according to the solid-liquid ratio of 1:1.5 (0.2-0.5mol / L, zeolite A better silver-loaded amount can be obtained), carry out the exchange reaction at 50°C in the dark for 2 hours, suction filter after standing, and dry to prepare the silver-loaded antibacterial agent, the grinding particle size is 10-20μm silver-loaded antibacterial agent, silver-loaded antibacterial The agent is introduced into the paper sheet according to two addition methods in scheme 1, one is directly added to the paper pulp at the pulpmaking stage, and the silver ion concentration per ton of dry paper is calculated according to the following formula: CAg + =K*W 1 (K is silver-loaded zeolite mass percentage of silver-loaded, W 1 is the mass fraction of silver-loaded zeolite added to each to...

Abstract

The invention discloses silver-loaded antibacterial paper.The silver-loaded antibacterial paper is prepared from a silver-loaded antibacterial agent, a softening agent, a dry strength agent, a wet strength agent, a drying agent, a retention agent, a sizing agent, an antibacterial agent, a dispersing agent and a decolorizer additive.The invention further discloses a preparing method of the silver-loaded antibacterial paper.The method comprises the following steps that pulping, pulp dispersing, pulp milling and pulp beating are carried out, the silver-loaded antibacterial agent is added into the pulp sizing agent, the sizing agent is conveyed, pulp is fed onto a net to be shaped and pressed into paper, pressing is carried out, and dry dehydration and paper forming are carried out.Compared with the prior art, the antibacterial paper and the antibacterial paper production method have the advantages that prebiotics and the antibacterial agent are used in the antibacterial paper in a combined mode, it is ensured that the antibacterial paper has the fast and good sterilization and bacteriostasis effects, can well restrain breeding and growth of microorganisms of the antibacterial paper, the damage to the quality of the antibacterial paper due to breeding of the microorganisms is avoided, and the quality of the antibacterial paper is ensured.

Description

technical field [0001] The invention relates to the field of papermaking, in particular to a silver-loaded antibacterial paper and a preparation method thereof. Background technique [0002] In modern life, people pay more and more attention to the hygiene and safety of the living environment, and put forward higher requirements for the safety of various products that directly contact with human skin or indirectly affect human health. Various antibacterial products should be shipped And born. [0003] Household paper is a daily necessities that are frequently used in human life and are in direct contact with human skin. Microorganisms can finally attach to household paper through various contact channels. When household paper containing microorganisms is used, the germs also come into contact with the skin, causing the risk of disease and affecting people's health. Therefore, people put forward higher requirements on the sterility and antibacterial properties of tissue pap...
