Abstract

The invention provides a liquid band-aid preparation method. The liquid band-aid preparation method comprises: uniformly mixing 60-80 parts by weight of ethanol, 0.5-3 parts by weight of camphor, 0.1-2 parts by weight of benzyl alcohol, 1-5 parts by weight of extract of panax notoginseng and 1-5 parts by weight of extract of witch hazel, then adding 20-30 parts by weight polyurethane-35 into the mixture and carrying out uniform stirring to obtain a product. The liquid band-aid has good gas permeability and good anti-inflammatory and analgesic effects, does not cause redness, swelling and itching and is prepared through simple processes.

Description

technical field [0001] The invention relates to a liquid band-aid and a preparation method thereof. Background technique [0002] Liquid Band-Aid is composed of film-forming material dissolved in a solvent and functional substances added. By smearing or spraying, it adheres tightly to the wounded part of the skin to form a protective film. Compared with traditional band-aids, it has the advantages of waterproof, breathable, simple and convenient to use, and not limited by the location of the wound. [0003] Existing liquid band-aids generally use cyanoacrylates, nitrocellulose, polyvinyl alcohol (PVA), polyvinyl acetal (PVB), chitosan, etc. as film-forming materials, adding functional substances to promote sterilization and anti-inflammation healing effect. However, in the prior art, the synthesis method is cumbersome, and phenomena such as redness, swelling and itching occur. [0004] CN104998295 A patent discloses a liquid band-aid and its preparation method. Its raw m...
