A kind of silver-containing antibacterial fabric coating glue and preparation and use method thereof

Abstract

The invention discloses a silver-containing antibacterial fabric coating glue and its preparation and application method. The fabric coating is composed of the following raw materials in parts by mass: 70-80 parts of water-based acrylic emulsion, 1-10 parts of silver-loaded inorganic antibacterial agent , 1-5 parts of dispersant, 1-5 parts of stabilizer, 10-20 parts of solvent. Preparation method: Add water-based acrylic emulsion and deionized water into the dispersion kettle, stir at room temperature for 5-20 minutes, stirring speed 200-500 rpm; add dispersant and stabilizer at one time, stir at room temperature for 10-30 minutes, stirring speed 200‑500 rpm; add silver-loaded inorganic antibacterial agent, particle size range 0.5‑3µm, ultrasonically oscillate for 30‑60 minutes; bake at 80‑100°C for 2‑3 hours after suction filtration to obtain the finished product. The invention can overcome the shortcomings of easy discoloration and agglomeration of the nano-silver sol, and can be evenly applied to fabrics after being dissolved in acetic acid, and has good and long-lasting antibacterial properties.

Description

technical field [0001] The invention belongs to the field of fabric antibacterial, and relates to an antibacterial coating adhesive and a preparation method thereof, in particular to a silver-containing antibacterial fabric coating adhesive, a preparation method and a use method thereof. Background technique [0002] With the rapid development of industry and the improvement of people's living standards, people's awareness of environmental hygiene and self-care is increasing. In daily life, people will inevitably come into contact with various bacteria, fungi and other microorganisms. These microorganisms can multiply rapidly in a suitable growth environment such as humidity and temperature, and spread diseases through contact, affecting people's physical and mental health. And all kinds of fabrics, especially fabrics in public places (such as hospital bedding, bed sheets, etc.), are often good habitats for these microorganisms and become an important source of disease trans...

AI Technical Summary

Problems solved by technology

The textile antibacterial agent has large particle size, wide distribution range, uneven particle size, activity needs to be improved, and application is obviously limited

[0005] In addition, the nano-silver antibacterial agent in the prior art is to add nano-silver particles directly to the detergent, but the nano-silver has problems such as easy discoloration in the solvent, not stable enough, and easy to agglomerate.
