Problems solved by technology

[0005] It is worth noting that silver is expensive as a heavy metal, and it is easy to change color when processed, and too much contact will cause certain damage to the human body; the disinfection and sterilization effect of zinc oxide photocatalyst can only be produced under the condition of light irradiation, and its effect is also Varies with light intensity and type of light source

Embodiment 1

[0023] A preparation method of an antibacterial finishing agent for textile fabrics includes the following steps:

[0024] Step 1: Add 63 parts of deionized water, 2 parts of aluminum-zirconium coupling agent, 2 parts of tridecafluorooctyltrimethoxysilane, and 15 parts of nano-zinc oxide to the stirred tank, stir, and heat to 62°C and keep it for 30 minutes. Remove excess coupling agent by repeated high-speed centrifugal separation with absolute ethanol for 5 times; filter cake is dried, ground, and sieved to produce modified nano-zinc oxide powder; 0.6 part of sodium persulfate and 20 parts of deionized water are dissolved to form Initiator aqueous solution, ready for use;

[0025] Step 2: Add 26 parts of quaternary ammonium salt antibacterial monomer, 8 parts of modified nano zinc oxide powder prepared in step 1, and 113 parts of deionized water into the reaction kettle, adjust the pH of the system to 7-8 with sodium carbonate, stir and raise the temperature To 65~68℃; quaternar...

Abstract

The invention relates to a preparation method for an antibacterial finishing agent used for a textile fabric. The preparation method comprises the following steps: adding deionized water, an aluminum-zirconium coupling agent, a fluorine-silicon coupling agent and nanometer zinc oxide into an agitation vessel, carrying out stirring and heating to 62 DEG C and maintaining the temperature for 30 min so as to prepare nanometer zinc oxide; adding quaternary ammonium salt monomer and deionized water into the reaction vessel, adjusting the pH value of the obtained system to 7 to 8 by using sodium carbonate and carrying out stirring and heating to 65 to 68 DEG C; and adding diallylamine and an aqueous solution of an initiator drop by drop within 2 h, carrying out a reaction for 2 h under a heat preservation condition, adding a solution composed of 0.2 part of silver nitrate and 20 parts of deionized water, carrying out uniform mixing under stirring, rapidly adding a solution composed of 0.2 part of sodium borohydride and 20 parts of deionized water and a carrying out a reduction reaction. Since the quaternary ammonium salt monomer is grafted on the surfaces of modified zinc oxide ions, safety, long-lasting action and high efficacy of the antibacterial finishing agent are realized.

Description

Technical field [0001] The invention relates to a method for preparing an antibacterial finishing agent for textile fabrics, in particular to a method for preparing an antibacterial finishing agent for textile fabrics, and belongs to the field of textile additives Background technique [0002] The materials that can kill or inhibit microorganisms are usually called antibacterial materials or antibacterial agents. Antibacterial agents for textiles can be roughly divided into three categories: natural antibacterial agents, organic antibacterial agents and inorganic antibacterial agents according to their ingredients. Natural antibacterial agents are mainly extracts of natural plants and animals. Due to resource constraints, there are certain difficulties in their application and promotion. Organic antibacterial agents have been used for more than 30 years, but organic antibacterial agents have disadvantages such as poor safety, microbial resistance, poor chemical stability, and poo...
