Abstract
The invention provides a nano silver sterile bandage and a process thereof. In the invention, a nano silver antibacterial material is added in an antibacterial fabric layer of a bandage for daily medical treatment, and the method thereof is as follows: utilizing a liquid-phase chemical reduction method to prepare nano silver to obtain spherical particles the particle size of which is 10-80nm, dispersing the particles to obtain nano silver solution with efficient antibiosis and wound repair activity, utilizing nano silver and 0.2-1% of adhesive FWT to form modified nano silver composite dispersion liquid, and utilizing the processes of impregnating, drying and finishing to adhere nana silver on the surface of the antibacterial fabric layer of the bondage, thus ensuring the nano silver sterile bandage to effectively kill various bacteria so as to accelerate wound healing.
Description
One, technical field:
The present invention relates to daily medical supplies and nano anti-biotic material field, particularly a kind of externally used antimicrobial is treated multiple traumatic infection and is repaired the nanometer silver bandage of wound.
Two, background technology:
Bandage is daily medical essential product, the bandage of selling only has simple wrapping mostly at present, hemostasis and the effect that stops wound further to infect, the inflammation wound of bacterial infection there is not therapeutic efficiency, and the antibacterial that has on the bandage of antibacterial action mostly is chemical organic antibacterial agent, produce certain drug resistance for human body easily, and antibiotic stability is not good.Day by day strengthen with health consciousness along with the people oneself is healthy, for the also corresponding raising of the requirement of antibiotic bandage.
Nanometer silver has the antibacterial activity more excellent than common silver owing to have the special construction and the performance of nano material, therefore in the anti-biotic material field wide application prospect is arranged.Few nanometer silver can produce powerful bactericidal action, can in several minutes, kill hundreds of pathogenic microorganism, broad-spectrum sterilization and can promote the healing of wound, the growth of cell and the reparation of damaged cell does not have any toxic reaction to human body, and skin is not found any irritant reaction yet, have no drug resistance, can effectively infiltrate subcutaneous bactericidal antiphlogistic, and produce bio-heating effectiveness, improve the microcirculation of damaged tissues, play analgesia, suppress bacterial reproduction, eliminate the effect of focus.Therefore utilize the nanometer silver inorganic antiseptic that bandage is carried out impregnation process, make this product have the advantage that stable persistency is good, drug effect is high, drug effect is long, safety has no drug resistance, and preparation technology is simple, cost is lower, and is convenient feasible.
Three, summary of the invention:
The objective of the invention is many shortcomings, produce a kind of nanometer silver bandage that has extremely strong bactericidal action and repair wound at traditional bandage existence.
The present invention takes following technical scheme: utilize lower-cost liquid phase chemical reduction legal system to be equipped with the spherical nano silver particles of 10～80nm size, and nanometer silver evenly spread in the aqueous solution, obtain 200～1000ppm concentration nano silver dispersion, utilize postfinishing process, nanometer silver is sticked to the bandage antibacterial fabric layer, be met the nanometer silver bandage of requirement.
Production stage of the present invention is as follows:
(1) utilize liquid chemical method with low cost to prepare nanometer silver;
(2) prevent the nano-powder reunion with dispersants such as PVP, form the nanometer silver solution of stable dispersion;
(3) the binding agent FWT of the nano silver dispersion body of 200～1000ppm concentration and 0.2%～1% is compounded to form the nano silver dispersion body of modification;
(4) by impregnation process technology nano silver particles is cohered at the bandage antibacterial fabric layer above-mentioned finely dispersed nanometer silver solution, 120 ℃～130 ℃ are cured 5～8min, and oven dry can obtain nano silver sterile bandage.
Four, the specific embodiment;
Embodiment one:
With the particle size for preparing is that the nano silver particles of the 0.1g of 10nm evenly spreads in the 500g water and forms dispersion, add FWT 1g then, behind the homodisperse, by infusion process nano silver particles in the above-mentioned nanometer silver solution is bonded in bandage antibiotic fabric laminar surface then, last 120 ℃ bake 6min, and oven dry can obtain nano silver sterile bandage.
Embodiment two:
With the particle size for preparing is that the nano silver particles of the 0.15g of 30nm evenly spreads in the 500g water and forms dispersion, add FWT 2.0g then, behind the homodisperse, by infusion process nano silver particles in the above-mentioned nanometer silver solution is bonded in bandage antibiotic fabric laminar surface then, last 120 ℃ are cured 6min, and oven dry can obtain nano silver sterile bandage.
Embodiment three:
With the particle size for preparing is that the nano silver particles of the 0.2g of 50nm evenly spreads in the 500g water and forms dispersion, add FWT 3g then, behind the homodisperse, by infusion process nano silver particles in the above-mentioned nanometer silver solution is bonded in bandage antibiotic fabric laminar surface then, last 120 ℃ bake 6min, and oven dry can obtain nano silver sterile bandage.
Embodiment four:
With the particle size for preparing is that the nano silver particles of the 0.25g of 50nm evenly spreads in the 500g water and forms dispersion, add FWT 4g then, behind the homodisperse, by infusion process nano silver particles in the above-mentioned nanometer silver solution is bonded in bandage antibiotic fabric laminar surface then, last 120 ℃ bake 6min, and oven dry can obtain nano silver sterile bandage.
Embodiment five:
With the particle size for preparing is that the nano silver particles of the 0.3g of 80nm evenly spreads in the 500g water and forms dispersion, add FWT 5g then, behind the homodisperse, by infusion process nano silver particles in the above-mentioned nanometer silver solution is bonded in bandage antibiotic fabric laminar surface then, last 120 ℃ bake 6min, and oven dry can obtain nano silver sterile bandage.
