Embodiment 1

[0031] 1. Under the catalysis of anhydrous aluminum chloride, para-substituted styrene with chloromethyl ether under the protection of nitrogen, extracted and dried to obtain p-halomethyl styrene; under the protection of nitrogen, tertiary amine and solvent were added to the above product Methanol, catalyst triethylamine, reflux at 50°C for 10 hours, extract and dry for 10 hours to obtain quaternized styrene; add maleic anhydride and reaction solvent toluene, inject initiator potassium sulfate, and pass ammonia gas to remove oxygen , polymerized in a constant temperature water bath at 60° C. for 7 hours; poured the product of step c into excess acetone to precipitate, and then washed and dried to obtain a quaternary ammonium antibacterial agent. Among them, the tertiary amine is propenyl didodecanyl tertiary amine, butenyl didodecanyl tertiary amine, propoxy didodecanyl tertiary amine, butoxy didodecanyl tertiary amine, propenyl One of ditetradecyl tertiary amine, butenyl dite...

Abstract

The invention discloses a preparation method of antibacterial paper containing a quaternary ammonium salt antibacterial agent, and belongs to the technical field of functional packaging paper. The quaternary ammonium salt antibacterial agent is a quaternization styrene-maleic anhydride copolymer. By adopting the two modes of surface coating and wet end addition, the quaternary ammonium salt antibacterial agent is added into the paper, and the most suitable quaternary ammonium salt antibacterial agent concentration, addition method, temperature and pressure are provided. In this way, the antibacterial paper is environmentally friendly and has the good and lasting antibacterial effect.

Description

technical field [0001] The invention relates to a method for preparing antibacterial paper containing quaternary ammonium salt antibacterial agents. Background technique [0002] In recent years, with the development of society and the improvement of people's living standards, for the needs of their own health, people pay more and more attention to the hygiene of their work and living environment, thus promoting the research and development of materials with antibacterial functions, and various antibacterial products come into being Health, such as antibacterial plastics, antibacterial ceramics, antibacterial coatings, antibacterial fabrics, etc., but there are few reports on antibacterial paper packaging products. [0003] Paper is an indispensable daily necessities in people's life, and the high fluidity of paper is one of the ways for bacteria to spread. Antibacterial paper packaging products have a wide range of uses and can be used for packaging of leather products, fo...
