Abstract
The invention discloses a nano-antibacterial bandage, which is characterized in that the invention consists of medical gauze and the medical binding agent which is coated on the medical gauze, wherein the medical binding agent consists of acrylic latex, polyurethane emulsion, non-ionic surfactant, defoamer, nano-TiO2 photocatalyst and purified water, and the pH value is regulated by nitrogen water. The invention has antibacterial function and improves the using value of bandage.
Description
Technical field
The invention belongs to a kind of medical bandage, specifically is a kind of medical bandage with antibacterial properties.
Background technology
The binding agent of existing traumatology binder only requires to have adhesive function, does not explicitly call for for whether binding agent is antibiotic.Binder such as resting period are long or storage environment is abominable, may cause the binder bacterial infection, when this binder uses, can cause the wounded's wound infection, and malpractice takes place.
Summary of the invention
The purpose of this invention is to provide a kind of medical nano antimicrobial bandages, have antibacterial functions, when the wounded used, wound is easy infection not, and itself longer resting period, and storage environment requires and can reduce.
Technical scheme of the present invention is as follows:
Nano antimicrobial bandages is characterized in that by hospital gauze, and is coated in the adhesive of medical composition on the hospital gauze, and the weight proportion of adhesive of medical is:
Acrylic emulsion is to contain 48% active matter 70-90
Polyaminoester emulsion is to contain 48% active matter 5-15
Nano-TiO
2Photocatalyst 5-15
Non-ionic surface active agent is to contain 70% active matter 0.1-0.3
Defoamer 0.05-0.15
It is 7-8 that ammonia is transferred system PH
Pure water is an amount of.
The weight proportion of adhesive of medical is:
Acrylic emulsion 80
Polyaminoester emulsion 10
Nano-TiO
2Photocatalyst 10
Non-ionic surface active agent X-405 0.2
Defoamer 0.1
It is 7.5 that ammonia is transferred system PH
Pure water is an amount of.
The preparation method of described adhesive of medical is characterized in that: take by weighing acrylic emulsion, transfer pH value with proper ammonia, add polyaminoester emulsion, mix homogeneously adds non-ionic surface active agent and defoamer, and mix homogeneously adds nano-TiO
2Photocatalyst, high speed dispersion, mix homogeneously, view volume are the thickness situation, can add appropriate amount of purified water, to regulate viscosity.
Acrylic emulsion plays the bonding agent effect, can be with nano-TiO
2Photocatalyst is fixed on the surface of binder; After the polyaminoester emulsion film forming, good springiness is mixed a small amount of polyaminoester emulsion in binding agent, can remedy elasticity and feel deficiency that simple acrylic emulsion brings to binder.
Nano-TiO
2It is the agent of a kind of oxide type photocatalysis antibacterial, its antibiotic mechanism is, under radiation of visible light, electrons excited produces active oxygen with the oxygen that is adsorbed on the coating surface, loses electronics simultaneously, and the hole oxidation hydroxyl of positively charged generates hydroxyl radical free radical, active oxygen and hydroxyl radical free radical have very strong oxidation susceptibility, can produce persistent antibacterial action.Nano-TiO
2Become the excited state electronics through original bound state electron-hole pair after the illumination, spread to grain surface in the hole, the quantity that electronics, hole arrive grain surface is many, photocatalysis efficiency height then, reactivity is big, good anti-bacterial effect, therefore particle is more little, electronics, hole recombination probability in particle is more little, and it is short more to arrive the surface time, the photocatalysis efficiency height.
Non-ionic surface active agent X-405 Main Ingredients and Appearance is a NPE, with 70% active matter supply.Have outstanding wettability and surface of good activity, can moistening and dispersing nanometer TiO
2
Because photocatalyst binding agent high speed dispersion is prone to a large amount of little foams, add defoamer, can eliminate foam, make the binder gluing even.
Ammonia is used to regulate the pH value of acrylic emulsion, and making the pH value of system is 7.5, mixes a spot of polyaminoester emulsion, is difficult for making system granule or breakdown of emulsion to occur.
Compare with prior art, the present invention has antibacterial functions, has improved the use value of binder.
The specific embodiment
One, nano antimicrobial bandages is characterized in that by hospital gauze, and is coated in the adhesive of medical composition on the hospital gauze, and the weight proportion of adhesive of medical is (Kg):
Acrylic emulsion (active matter content 48%) 80
Polyaminoester emulsion (active matter content 48%) 10
Nano-TiO
2Photocatalyst 10
Non-ionic surface active agent Triton X-405 (active matter content 48%) 0.2
Defoamer EDW-707 0.1
It is 7.5 that ammonia is transferred system PH
Pure water is an amount of.
Two, adhesive of medical preparation method
Take by weighing acrylic emulsion, transfer pH value 7.5 with proper ammonia, add polyaminoester emulsion, mix homogeneously adds non-ionic surface active agent Triton X-405, and defoamer, and mix homogeneously adds nano-TiO
2Photocatalyst, high speed dispersion, mix homogeneously, view volume are the thickness situation, can add appropriate amount of purified water, to regulate the viscosity of photoresist coating process.
