Problems solved by technology

[0005] Most of the existing antibacterial agents for papermaking use metal elements as effective antibacterial materials, but heavy metal elements have certain neurotoxicity and are not easy to contact the human body for a long time, and a large amount of heavy metal elements put into the environment also cause certain damage to the environment

Abstract

The invention relates to a preparation method of antibacterial material for papermaking. The method comprises: adding, by weight, cellulose acetate microspheres, carboxymethyl chitosan, (4-carboxylphenylacetenyl)trimethyl silicane, 5-bromo-4-chloro-3-indolyl-beta-d-xyloside, tetrachloro di(cyclohexyl sulfydryl) titanium, a 1-butylsulfo-3-methylimidazole trifluoromethane sulfonate ionic liquid, p-toluene sulfonic acid, and water into a reaction vessel, raising the temperature, performing a reaction, performing filtration after the reaction is over, and performing washing and drying to obtain acellulose-acetate-microsphere-loaded antibacterial material for papermaking.

Description

technical field [0001] The invention relates to a preparation method of an antibacterial agent, in particular to a preparation method of an antibacterial material for papermaking. Background technique [0002] Paper products have been used in all aspects of modern life, and a considerable number of products are in direct contact with the human body in daily life, such as office paper, toilet paper, cleaning paper, etc. Since most paper products are made of natural fibers, they are vulnerable to bacteria, especially after the paper is wet, the fiber macromolecular structure is easily hydrolyzed by the enzymes secreted by bacteria to release nutrients, resulting in the proliferation of bacteria, so in the production process It is necessary to add antibacterial materials or antibacterial agents to eliminate bacteria or inhibit the growth of bacteria. [0003] CN104389240A discloses a preparation method of paper nano antibacterial agent. Methods The preparation of cellulose mo...
