Abstract

The invention discloses a medical silica gel adhesive tape. The medical silica gel adhesive tape comprises a gelatinous layer and a cloth base material, wherein the cloth base material comprises one of a PE (polyethylene) film, a TPU (thermoplastic polyurethane) film and foam and a non-woven fabric material, and the adhesive tape comprises one of the PET film, the TPU film and the foam, the non-woven fabric material and the gelatinous layer sequentially from outside to inside. The adhesive tape provided by the invention is good in air permeability, good in effect of jointing with skin and less prone to degumming during the use, and can be used repeatedly.

Description

technical field [0001] The invention belongs to the field of medical adhesive tapes, in particular to a medical silicone adhesive tape and a preparation method thereof. Background technique [0002] Adhesive tapes commonly used in medicine and daily life usually have a two-layer structure, one is the base layer, the other is the adhesive layer, and the adhesive or substrate coating layer may cause the tape to be airtight due to their respective components. , affecting the comfort of use. [0003] Although the tapes currently on the market can achieve a good bonding effect at the beginning, they are not skin-friendly enough, and often tear the skin and hair, which affects the use experience, and if the bonding part is moved a little, it is prone to degumming; now Some adhesive tapes do not adhere well to the skin, and are prone to degumming during use. [0004] After the adhesive tape is used once, it cannot be pasted again due to the poor sticking effect. After the ordinar...
