Method for preparing multifunctional nano silver solution

Abstract

The invention discloses a method for preparing a multifunctional nano silver solution. A nano silver solution with the grain diameter of 20-100nm is carried by utilizing a surface modified tourmaline particle. The preparation method has simple process, mild reaction condition and lower preparation cost and meanwhile has the characteristics of broad-spectrum antibacterial property, anion release performance, favorable water absorptivity, and the like. The invention can be widely applied to a hygienic product and an appliance for daily life.

Description

technical field

[0001] The invention relates to a preparation method and application of a multifunctional nanometer silver solution. Background technique

[0002] Silver has broad-spectrum antimicrobial properties. Trace amounts of silver in solution have the ability to kill bacteria. Silver ions can block bacterial respiratory enzyme system and interfere with bacterial metabolism to cause bacterial death, but the instability of silver ions in solution limits its popularization and application. Nano-silver is the processing of metallic silver into nano-scale particles, which has made a qualitative leap in the bactericidal ability of silver. At a concentration of a few parts per million, it can kill common bacteria, fungi, mycoplasma, chlamydia, etc. microorganism. Nano-silver prepared by nanotechnology has stable chemical properties and has excellent properties in electricity, optics and catalysis. Nano-silver has been widely used in the preparation of antibacterial mate...
