Macromolecular microballoon sphere silver-carrying antibiotic finishing agent and preparation method thereof

Abstract

The invention relates to a macromolecular microballoon sphere silver-carrying antibiotic finishing agent and a preparation method thereof. The macromolecular microballoon sphere silver-carrying antibiotic finishing agent is prepared by the reaction of silver ammonia solution, reducer and macromolecular microballoon sphere dispersion liquid the surface of which is provided with carboxyl, and is particularly realized by adsorbing silver ions at the surface of the macromolecular microballoon sphere prepared by the copolymerization of hydrophobicity monomer and hydrophilicity monomer containing carboxyl and by the reduction reaction to enable the silver particles to be deposited on the macromolecular microballoon sphere. The antibiotic substance silver of the antibiotic finishing agent is evenly deposited on the surface of the macromolecular microballoon sphere in a granular mode, and the problem that the antibiotic effect is reduced because of the transfer of the silver is avoided, thereby the antibiotic effect of the antibiotic agent is improved. In addition, the antibiotic agent has good film forming property to enable the antibiotic property to be more durable.

Description

technical field [0001] The invention relates to a polymer microsphere silver-loaded antibacterial finishing agent and a preparation method thereof. Background technique [0002] In the early days, the antibacterial of textiles mainly used chemicals to endow textiles with antibacterial, deodorant, mildew-proof and insecticidal functions. These chemicals mainly include inorganic salts, metal organics, iodophors (slowly releasing iodine), phenolic compounds such as: PcP (pentachlorophenol), and thiophenol, antibiotics, heterocyclic compounds containing anionic groups, nitro compounds, urea and related compounds, formaldehyde derivatives such as: BCA (O-bromocinnamaldehyde), amines, organic Tin and organic mercury, etc. They are cheap. However, many chemicals are harmful to the human body and are not easy to degrade naturally in the environment. Many of them have been banned and restricted by the country. [0003] Currently used antibacterial agents are generally divided into ...

AI Technical Summary

Problems solved by technology

The ionic antibacterial agent mainly loads metal ions with antibacterial effect on a certain carrier, and exerts antibacterial effect by slowly releasing metal ions, but its disadvantages are also obvious, such as weak anti-mildew and anti-fungal effects, and high cost. Easy to change color, etc.; photocatalytic antibacterial agents mainly achieve antibacterial purposes through catalytic oxidation in the presence of ultraviolet rays and oxygen, but it is necessary to solve the uniform dispersion of nano-antibacterial agents in the finishing liquid and the combination with fibers

[0006] Natural antibacterial agents are natural plant extracts, such as mustard extract, green mustard essential oil, tea polyphenols, etc. It has high antibacterial efficiency, safety and non-toxicity, but has poor heat resistance, short duration of drug effect, and difficult processing. Large-scale commercialization has not been achieved

In addition, chitosan and its derivatives have been widely concerned as antibacterial agents in recent years. Although a lot of applied research has been done in textile finishing, it is still basically in the laboratory stage.
