Embodiment 1

[0040] The raw material formula of biological antibacterial film-forming liquid medical dressing is as follows:

[0041] Nitrocellulose (N%=11.0%) 50 parts;

[0042] 25 parts of α-octyl cyanoacrylate;

[0043] D-limonene 20 parts;

[0044] 40 parts of dopamine-graphene oxide;

[0045] 60 parts of benzyl alcohol;

[0046] Castor oil 20 parts;

[0047] 5 parts of camphor;

[0048] 20 parts of isopropyl palmitate;

[0049] 1 part clove oil;

[0050] 359 parts of ethanol;

[0051] 260 parts of ethyl acetate;

[0052] 140 parts of butyl acetate.

[0053] Wherein, the preparation method of dopamine-graphene oxide powder is as follows: 1 part of graphite oxide is added to 200 parts of deionized water, and ultrasonically stirred for 0.5 h at 5° C. to obtain a graphene oxide suspension. Add 3 parts of dopamine hydrochloride to adjust the pH value to 9.0; stir and react at 60°C for 24h. Centrifuge, wash 3 times with water, and dry in vacuum.

Abstract

The biological antibacterial film-forming liquid medical dressing comprises a film-forming material, a bactericide and an organic solvent, the liquid medical dressing further comprises dopamine-graphene oxide. The film-forming material is selected from a combination of nitrocellulose and alpha-cyanoacrylate octyl ester. In addition, the invention further discloses a preparation method of the biological antibacterial film-forming liquid medical dressing. Compared with the prior art, the biological antibacterial film-forming liquid medical dressing is better in air permeability and better in antibacterial property.

Description

technical field [0001] The invention belongs to the technical field of medical dressings and relates to a biological antibacterial film-forming liquid medical dressing and a preparation method thereof. Background technique [0002] Skin is an important part of the human body. When the skin is damaged, wound healing is a complex biological process, including hemostasis, inflammation, cell proliferation, scar formation, and regeneration of the epidermis and other tissues. [0003] An important means of treating skin wounds is the use of medical dressings. At present, medical dressings are mainly divided into traditional medical dressings, synthetic medical dressings and biological medical dressings. [0004] Traditional medical dressings mainly include gauze and artificial synthetic fibers. This type of medical dressing has the characteristics of being able to protect the wound surface, having a certain absorption capacity for wound exudate, simple to make, and low in cost. ...
