Method for preparing antibacterial agent achieving antibacterial effect on decorative textile fabric

Abstract

The invention relates to a method for preparing antibacterial agent achieving the antibacterial effect on textile finishing fabric. The method comprises the following steps: mixing silane and tertiary amine by the ratio of 1:1.5-3 in a 100mL 4-neck flask equipped with a thermometer, a reflux condensation tube and a stirrer; adding 0.15%-3% sodium iodide as a catalyst and 1.2%-2.5% antioxidant as well as organic solvent at the same time to the mixture; feeding in protective nitrogen; controlling the temperature of the reaction system within 65 to 80 DEG C; stirring and reacting; and cooling and discharging after the reaction to obtain the light yellow liquid antibacterial finishing agent, wherein the reaction equation is shown as below.

Description

technical field

[0001] The invention relates to a preparation method of an antibacterial agent for textile decorative fabrics with antibacterial function, which belongs to the field of textile decorative fabric manufacturing. Background technique

[0002] CNCN1568704A, title "a composite nano-antibacterial material and its preparation method and product", 1. Aiming at the deficiency of a single nano-antibacterial material, a nano-combined antibacterial technology was used to combine antibacterial materials with different antibacterial effects to prepare a composite nano-antibacterial material. The synergy and coupling between nanoparticles greatly improve the antibacterial ability; 2. The antibacterial material developed by this method has a broad-spectrum antibacterial function, and it is effective against Staphylococcus aureus, pathogenic Escherichia coli, Neisseria gonorrhoeae, syphilis, etc. A variety of germs (poisons) have a good killing effect; 3. The method can be us...
