Liquid band-aid and preparation method thereof

Abstract

The invention relates to the technical field of medical dressings, in particular to a liquid band-aid and a preparation method thereof. At present, the commercially available liquid band-aid is poor in adhesive force on the skin surface, and after the liquid band-aid is dried to form a film, the film forming position is prone to large deviation. On the basis of the problems, a certain amount of fumed silica and mica powder are added into the components of the liquid band-aid, and due to the existence of the fumed silica, the rheological property of a product can be remarkably improved, the spraying accuracy can be improved, and the deviation rate of a film can be reduced; due to the existence of the mica powder, a film formed after the liquid band-aid is dried has a good light effect, and due to the synergistic effect of the mica powder and the fumed silica, the deviation rate of the film is further reduced.

Description

technical field [0001] The invention relates to the technical field of medical dressings, in particular to a liquid band-aid and a preparation method thereof. Background technique [0002] The spray-type liquid band-aid has the functions of protecting the wound surface, waterproofing, and preventing bacteria. At present, the commonly used film-forming materials for commercially available liquid band-aids are acrylic resins, polyurethane resins, or polyvinyl alcohol resins. The film-forming speed of related products is fast, but the adhesion between liquid band-aids and the skin surface is poor. prone to large deviations. [0003] With the upgrading of consumption concepts, people not only require liquid band-aids to have the properties of wound protection, water resistance, and bacteria resistance, but also require liquid band-aids to have a good appearance after film formation, such as glossiness.

Problems solved by technology

[0004] Aiming at the problems existing in the prior art, the technical problem to be solved by the present invention is: the adhesion force of the currently commercially available liquid band-aid on the skin surface is poor, and after drying and forming a film, the film-forming position tends to deviate greatly
