Abstract

The invention provides a medical adhesive plaster and a preparation method thereof. The adhesive plaster is prepared from the following raw materials in parts by weight: 15-25 parts of isoprene rubber, 20-32 parts of zinc oxide, 18-28 parts of stearic acid, 3-8 parts of hydroxyl silicone oil, 4-10 parts of wool fat, 0.2-0.6 part of dioctyl sebacate, 5-12 parts of asarum, 5-12 parts of cinnamon and 5-12 parts of fructus psoraleae. The adhesive plaster provided by the invention is good in tensile strength and high in bonding strength and has the pharmacological actions of clearing damp, relieving pain and the like.

Description

technical field [0001] The invention relates to the field of medical supplies, in particular to a medical adhesive plaster and a preparation method thereof. Background technique [0002] Medical adhesive plaster is used for bandaging and reinforcement of fixed dressings and catheters, etc. It is comfortable to stick and has no pain when it is removed; it has long-lasting stickiness, no residue when it is removed, no skin wet oil and allergies, and can be used on various parts of the body. The best choice for hospital and household accessories. But, the effect of existing medical adhesive plaster only lies in these, does not possess the pharmacological effects such as damp-dispelling, pain relief, and this has limited the development of medical adhesive plaster to a certain extent. [0003] Contents of the invention [0004] Technical issues solved: Aiming at the shortcomings of existing medical adhesive plasters, the invention provides a medical adhesive plaster and a p...
