Problems solved by technology

In ancient times, when making plasters, substances such as oil and dan were added to form a film, but the production method was only suitable for family workshops and could not meet the needs of large-scale industrial production, so plaster glue appeared.
[0003] However, the traditional plaster glue is a kind of hot melt adhesive. Because of its ultra-high temperature (150-160°C), it is easy to damage the internal structure of the traditional Chinese medicine components, resulting in the failure of the medicine, and the medicine content is only up to 100% of the whole ointment quality. 30/30
[0004] In addition, many types of plasters currently do not have good air permeability, resulting in the growth of bacteria on the plasters, which can easily cause problems such as ...

Abstract

The invention discloses a waterproof breathable biological soft shell plaster and a preparation method thereof. The basic structure of the plaster sequentially comprises release paper (6), a waterproof breathable film (5), an air suction layer (4), a base lining (3), a substrate (2) and release paper (1) from outside to inside. The release paper can be peeled off and is used as a plaster shell; the waterproof breathable film is a film made of high-molecular compounds of polyether sulfone and aryl polyether; the air suction layer is an activated carbon powder layer (7) added between the base lining and the waterproof breathable film; the base lining is a non-stick gauze layer; components of the matrix comprise traditional Chinese medicine powder and additives, and the additives comprise a film-forming agent, an antioxidant, a wetting agent, a bacteriostatic auxiliary agent, a light absorbing agent, a dispersing agent and the like. The waterproof breathable biological soft-shell plaster provided by the invention ensures the curative effect of traditional Chinese medicines, has good waterproof and breathable properties, and does not cause allergy and other damages to the skin.

Description

technical field [0001] The invention relates to a waterproof and breathable biological soft shell plaster and a preparation method thereof, belonging to the technical field of plasters. Background technique [0002] External application of traditional Chinese medicine is an important method of traditional Chinese medicine. It has a good effect on healing trauma and even some internal injuries, and it is also one of the easiest and safest methods. In ancient times, when making plasters, substances such as oil and dan were added to form a film, but the production method was only suitable for family workshops and could not meet the needs of large-scale industrial production, so plaster glue appeared. [0003] However, the traditional plaster glue is a kind of hot melt adhesive. Because of its ultra-high temperature (150-160°C), it is easy to damage the internal structure of the traditional Chinese medicine components, resulting in the failure of the medicine, and the medicine c...
