Silver-containing antibacterial fabric coating adhesive as well as preparation and application methods thereof

Abstract

The invention discloses a silver-containing antibacterial fabric coating adhesive as well as preparation and application methods thereof. The fabric coating adhesive is composed of the following raw materials in parts by mass: 70-80 parts of waterborne acrylic emulsion, 1-10 parts of a silver-loaded inorganic antibacterial agent, 1-5 parts of a dispersing agent, 1-5 parts of a stabilizer and 10-20 parts of a solvent. The preparation method comprises the following steps: adding waterborne acrylic emulsion and deionized water into a dispersing kettle, and stirring for 5-20 minutes at room temperature and at the stirring speed of 200-500 rpm; adding the dispersing agent and the stabilizer in one time, and stirring for 10-30 minutes at room temperature and at the stirring speed of 200-500 rpm; adding the inorganic antibacterial agent, wherein the particle size ranges from 0.5 [mu]m to 3 [mu]m, and carrying out ultrasonic oscillating for 30-60 minutes; after suction filtration, drying for 2-3 h at 80-100 DEG C so as to obtain a finished product. According to the invention, the defects that nanometer silver sol is easy to decolorize and agglomerate are overcome, the fabric is uniformly coated with the coating adhesive after the coating adhesive is dissolved in acetic acid and the coating adhesive has a good and long-lasting antibacterial property.

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...

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.
