Abstract

The invention discloses a process method for preparing a high-performance medical UV adhesive, wherein the process method comprises the steps: selecting the following raw materials for preparation: 80-90 parts of n-butyl cyanoacrylate, 30-40 parts of A type tackifying resin, 10-20 parts of B type tackifying resin, 2-3 parts of sulfur dioxide, 3-4 parts of hydroquinone, 5-10 parts of a softener, 1-2 parts of an antioxidant, 1-2 parts of an anti-aging agent and 5-8 parts of a plasticizer. The medical adhesive prepared by the preparation method disclosed by the invention is prepared from n-butyl alpha-cyanoacrylate, can be suitable for skin and does not generate irritant reaction; and by adding sulfur dioxide and hydroquinone in the preparation process, the adhesive can achieve a certain antibacterial and bactericidal effect in the use process, so that the risk that a wound is infected with bacteria is reduced; and in addition, the antioxidant and the anti-aging agent are added in the preparation process, so that the aging resistance and the oxidation resistance of the adhesive can be effectively improved, and the effective service time of the adhesive can be prolonged.

Description

technical field [0001] The invention relates to the technical field of medical articles, in particular to a process for preparing a high-performance medical UV adhesive. Background technique [0002] Medical hydrocolloid pressure-sensitive adhesive has the characteristics of strong water absorption, strong adhesion, good biocompatibility, no pollution, and no solvent. In recent years, it has been widely used in surgical wounds and stomas, dermatology, mattresses, etc. Drag, infectious ulcers and other medical fields. [0003] However, during the use of existing medical adhesives, due to their own oxidative properties, oxidation is very easy to occur in the process of use and storage, and the oxidized medical adhesives cannot be used, resulting in adhesive waste. Contents of the invention [0004] Based on the technical problems existing in the background technology, the present invention proposes a process for preparing a high-performance medical UV adhesive. [0005] A...
