Abstract
The invention discloses a kind of preparation method and applications of light-exposed non-discolouring Ag-containing solution, specially chemical industry solutions preparation technical field.The preparation method comprises the following steps: being matched according to raw material, weigh 5-6 parts of silver peroxides and be added in 930-950 parts of pure water, be protected from light stirring 1 hour, until being added dropwise concentrated phosphoric acid 8-12 parts without blocky-shaped particle, adjusts PH=2-3, continue stirring 0.5 hour, 30%H is added dropwise2O228-32 parts, Ag2O2It is gradually dissolved, until solution is clear and transparent, then adds 30%H2O218-22 parts, continues stirring 0.5 hour, stand overnight, that is, light-exposed non-discolouring Ag-containing solution is made.This Ag-containing solution overcomes the shortcomings that common silver ion light-exposed discoloration, expands the range of silver-ion antibiotic application.And preparation process is simple, advantage of lower cost.Manufactured Ag-containing solution can be applied in multiple fields, and application range is wider.
Description
Technical field
The present invention relates to a kind of preparation method and applications of light-exposed non-discolouring Ag-containing solution, prepared by specially chemical industry solutions
Technical field.
Background technique
The anti-microbial property of silver gains public acceptance already, and existing decades history is widely applied in many fields, in medicine
Aspect, such as wound, the product applied in gynaecology, domestic also You Jinshijia manufacturing enterprise.Since there are maximum for silver ion itself
Disadvantage is exactly light-exposed discoloration, from brown up to black.Discoloration can faster especially under high temperature, strong light.Some enterprises are in order to prevent
The generation of discoloration has selected nano silver not easy to change to replace ionic silver.Both at home and abroad many studies have shown that, nano silver be possible to from
The mucous membrane of human body enter blood and can the poisoning of building up property, so domestic approving authorities at different levels there is no reply nano silver so far
It can be used for human body mucous membrane, such as gynaecology and the antimicrobial product of wound class.The further drawback of nano silver is not so good as in the rate of sterilization
Ionic silver, that is to say, that reach the product of identical sterilizing rate, the content of nano silver is greater than the content of ionic silver, both increases in this way
Cost is added, and difficulty can have been caused to manufacture craft.
Summary of the invention
The purpose of the present invention is to provide a kind of preparation method and applications of light-exposed non-discolouring Ag-containing solution.
To achieve the above object, the invention provides the following technical scheme: a kind of preparation side of light-exposed non-discolouring Ag-containing solution
Method are as follows: matched according to raw material, weigh 5-6 parts of silver peroxides and be added in 930-950 parts of pure water, it is small to be protected from light stirring 1
When, until being added dropwise concentrated phosphoric acid 8-12 parts without blocky-shaped particle, PH=2-3 is adjusted, continues stirring 0.5 hour, 30%H is added dropwise2O228-32
Part, Ag2O2It is gradually dissolved, until solution is clear and transparent, then adds 30%H2O218-22 parts, continue stirring 0.5 hour, stands
Overnight, that is, light-exposed non-discolouring Ag-containing solution is made.
Preferably, other silver for using silver peroxide in the preparation method, but being not limited in addition to silver peroxide
Compound.
Preferably, the phosphoric acid used in the preparation method, but other inorganic acids being not limited in addition to phosphoric acid, it is organic
Acid.
Preferably, the reducing agent in the preparation method is hydrogen peroxide, but it is not limited to apart from hydrogen peroxide its
His reducing agent.
Preferably, the concentration of the light-exposed non-discolouring silver ion solution of the preparation is in 0.001-1%.
Can be applied after light-exposed non-discolouring Ag-containing solution dilution prepared by the present invention antibacterial gel, air cleaner spray,
Hygenic towelette, sanitary napkin, the fields such as hand cleanser.
Compared with prior art, beneficial effects of the present invention are as follows: it is light-exposed that this Ag-containing solution overcomes common silver ion
The shortcomings that discoloration, expands the range of silver-ion antibiotic application.And preparation process is simple, advantage of lower cost.Manufactured argentiferous
Solution can be applied in antibacterial gel, air cleaner spray, hygenic towelette, sanitary napkin, the multiple fields such as hand cleanser, application range compared with
Extensively.
Specific embodiment
Technical solution of the present invention is clearly and completely described below in conjunction in the embodiment of the present invention, it is clear that institute
The embodiment of description is only a part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention,
Every other embodiment obtained by those of ordinary skill in the art without making creative efforts, belongs to this hair
The range of bright protection.
Embodiment
A kind of preparation method of light-exposed non-discolouring Ag-containing solution: 5g silver peroxide (Ag is weighed2O2) 940g pure water is added,
It is protected from light stirring 1 hour, until concentrated phosphoric acid about 10g is added dropwise without blocky-shaped particle, until PH=2-3, continues stirring 0.5 hour, is added dropwise 30%
H2O2About 30g (meeting bubbling-oxygen), Ag2O2It is gradually dissolved, until solution is clear and transparent, then adds 20g, continue stirring 0.5
Hour, it stands overnight, this solution argentiferous about 0.44%.
Application example
By light-exposed non-discolouring Ag-containing solution manufactured in the present embodiment press surface compositions can be configured to it is light-exposed non-discolouring colourless
Transparent antibacterial gel.It being fitted into transparent polyethylene pipe, illumination 20 days are unchanged, to Escherichia coli, staphylococcus aureus,
The bacteriostasis rate of Candida albicans was in 2 minutes >=90% (argentiferous 0.005% in colloid) of arrival.
The formula of colloid:
The air cleaner spray that light-exposed non-discolouring Ag-containing solution prepared by embodiment is pressed to surface compositions preparation, to large intestine bar
