Problems solved by technology

The adhesive tape used has poor air permeability, and the water vapor and sweat normally secreted by the human body cannot penetrate this layer of adhesive tape, so it has a soaking effect on the local skin. The specific performance is that the local skin is wrinkled and susceptible to infection.
[0003] At present, there are some liquid band-aid products on the market, but the film-forming effect of these liquid band-aid products is poor, they are easy to fall off from the skin and have a lot of peculiar smell, and they cannot achieve a good anti-infection effect

Embodiment 1

[0026] Weigh nitrocellulose 0.5Kg, castor oil 0.06Kg, hydrogenated castor oil 0.05Kg, dioctyl phthalate 0.2Kg, benzyl alcohol 1.7Kg, ethyl acetate 1.5Kg, butyl acetate 5.5Kg, isopropanol 0.49 Kg. After mixing the above-mentioned components, the measured pH value is 6.8, which meets the requirements of pH, and the liquid band-aid is obtained. The viscosity of the liquid band-aid was measured at 25°C to be 24.3 Pa·s.

Embodiment 2

[0028] Weigh nitrocellulose 0.55Kg, castor oil 0.055Kg, hydrogenated castor oil 0.06Kg, dioctyl phthalate 0.195Kg, benzyl alcohol 1.74Kg, ethyl acetate 1.49Kg, butyl acetate 5.4Kg, isopropanol 0.51 Kg. After mixing the above-mentioned components, the measured pH value is 6.85, which meets the pH requirement, and the liquid band-aid is obtained. The viscosity of the liquid band-aid was measured at 25°C to be 24.7 Pa·s.

Embodiment 3

[0030] Weigh nitrocellulose 0.6Kg, castor oil 0.05Kg, hydrogenated castor oil 0.07Kg, dioctyl phthalate 0.19Kg, benzyl alcohol 1.78Kg, ethyl acetate 1.48Kg, butyl acetate 5.35Kg, isopropanol 0.48 Kg. After mixing the above-mentioned components, the measured pH value is 6.95, which meets the pH requirement, and the liquid band-aid is obtained. The viscosity of the liquid band-aid was measured at 25°C to be 24 Pa·s.

Abstract

The invention provides a liquid woundplast and a preparation method thereof, and belongs to the field of medical supplies. The liquid woundplast is prepared by mixing nitrocellulose, castor oil, hydrogenated castor oil, dioctyl phthalate, phenylcarbinol, ethyl acetate, butyl acetate and isopropyl alcohol and then adjusting a pH value to 6-8. After the prepared liquid woundplast is applied on a wood surface, the liquid woundplast can rapidly form a film in 1-2 min, thereby effectively isolating invasion of moisture, dust, dirt and bacteria, protecting wounds against infection and accelerating healing; and the liquid woundplast is soft, smooth, good in fitting property and not easy to fall off.

Description

technical field [0001] The invention relates to the field of medical supplies, and in particular to a liquid band-aid and a preparation method thereof. Background technique [0002] The band-aids currently on the market are usually composed of a long adhesive plaster with a small piece of drug-soaked gauze in the middle. The adhesive tape used has poor air permeability, and the water vapor and sweat normally secreted by the human body cannot penetrate this layer of adhesive tape, so it has a soaking effect on the local skin. The specific performance is that the local skin is wrinkled and susceptible to infection. [0003] At present, there are some liquid band-aid products on the market, but the film-forming effect of these liquid band-aid products is poor, they are easy to fall off from the skin and have a lot of peculiar smell, and they cannot achieve a good anti-infection effect. Contents of the invention [0004] The purpose of the present invention is to provide a li...
