Preparation method of water soluble antimicrobial polyacrylate silver salt

Abstract

Disclosed is a preparation method of water soluble antimicrobial polyacrylate silver salt. The water soluble antimicrobial polyacrylate silver salt is synthesized by dissolving a water soluble polyacrylate comprising sodium carboxylic group (-COONa) or potassium carboxylic group (-COOK) in water and then partially changing the sodium carboxylic group or potassium carboxylic group of the water soluble polyacrylate to silver carboxylic group (-COOAg) using silver salt in aqueous solution. Next, ultrafiltration membrane is used to remove the sodium salt or potassium salt generated from the metal ion exchanging procedure. The last step is to remove water from the ultrafiltration treated aqueous solution of polyacrylate silver salt to give water soluble antimicrobial polyacrylate silver salt.

Description

technical field [0001] The invention relates to a preparation method of a water-soluble antibacterial acrylic polymer silver salt. Background technique [0002] Bacteria have a huge impact on human life. It affects human health, causing disease and death. Therefore, antibacterial has become a necessity. So far, most antibacterial agents exist in the form of small molecules. They Used in antibacterial agents or as food preservatives, and can also be used for disinfection and sterilization of water or soil. Small molecule antibacterial agents have unsolvable shortcomings, such as residual toxicity to the environment, short-term antibacterial effect, and easy absorption The harm caused to the human body, etc., the way to solve these problems is to use polymer antibacterial agents. General polymer antibacterial agent is to connect the molecule with antibacterial effect on the polymer main chain, which can reduce the toxicity of antibacterial molecules, reduce the impact on the ...
