Liquid adhesive bandage and preparation technology thereof

Abstract

The invention relates to the technical field of medical supplies, specifically to a liquid adhesive bandage and a preparation technology thereof. The liquid adhesive bandage is prepared by free radical polymerization of an acrylate soft monomer, an acrylate hard monomer, a functional monomer, an initiator and a solvent for the preparation of a film-forming main body and with the assistance of a functional auxiliary agent. The liquid adhesive bandage can be applied on a wounded part, and then a layer of soft, non-toxic and non-irritating skin protection film which is not easy to peel off is rapidly formed on the wound surface. The film has good water resistance, air permeability and adhesiveness, prevents outside foreign matter and microorganisms from invading and infecting wounds, and hasthe effect of protecting the wound surface and promoting wound healing. The liquid adhesive bandage is direct and simple to use, is beautiful, comfortable and effective, is suitable for wounds of burn, scald, bruise, scratch, dactylotome cracking, chapped skin, chilblain, etc. and small wounds caused by other trauma, has hemostasis and wound protection effects, and is also suitable for superficialwounds caused after face-lifting, skin ulcer of patients with diabetes or chemotherapy, etc.

Description

technical field [0001] The invention relates to the technical field of medical supplies, in particular to a liquid band-aid and a preparation process thereof. Background technique [0002] People often have skin trauma and damage in their daily life. There will be different degrees of tissue necrosis and blood vessel rupture and bleeding in the local wound, and an inflammatory reaction will appear, causing local redness and swelling. Therefore, promoting wound healing has become an important research topic in the field of wound repair. [0003] Appeared in the early 20th century, the wound dressing plays a role in protecting the wound from external aggression during the wound healing process, including reducing physical contact damage and reinfection with microorganisms such as bacteria. Traditional wound dressing, also known as benzalkonium chloride paste, commonly known as bactericidal elastic wound dressing, is the most commonly used surgical drug in daily life, commonly...

Problems solved by technology

However, the adhesive tape used has poor air permeability, and the water vapor and sweat secreted by the human body cannot volatilize normally, which will soak the skin
