Problems solved by technology

However, compared with silk tape, the quality is not stable enough. The main reason is that the unwinding force is difficult to control.
Often the unwinding force is too large, it is very difficult to unwind during use, it is very laborious, and it brings inconvenience to users

Abstract

The invention relates to a releasing agent for a medical silk adhesive tape, which comprises the following components in percentage by weight: 1-9% of hydrogen-containing silicone oil, 1-9% of cationic hydroxy silicone oil, 0.1-0.3% of metal salt crosslinking agent and the balance of water, wherein the metal salt crosslinking agent is aluminum trichloride, zinc acetate or dibutyltin dilaurate. In the invention, the used water-soluble releasing agent comprises the main components of hydrogen-containing silicone oil and cationic hydroxy silicone oil and a proper amount of metal salt crosslinking agent, and is prepared by mixing and stirring the three components with water. When being coated on the other surface of a silk adhesive tape substrate, the releasing agent product provided by the invention can greatly reduce the unwinding force of the adhesive tape; and the adhesive tape can not slip off by itself even if the unwinding force is quite small, thereby ensuring that the adhesive tape is convenient and labor-saving to use.

Description

technical field [0001] The invention relates to a water-soluble anti-adhesive agent formula, in particular discloses an anti-adhesive agent for medical silk cloth tapes. Background technique [0002] At present, there are three kinds of medical tapes commonly used in hospitals, pharmacies and families at home and abroad: non-woven tape, polyethylene film tape and silk tape. Among them, the production process of non-woven tape and polyethylene film tape is relatively mature, and the quality is guaranteed. However, compared with silk tape, the quality is not stable enough. The main reason is that the unwinding force is difficult to control. Usually, the unwinding force is too large, and it is very difficult and laborious to unwind during use, which brings inconvenience to users. The reason for this factor is that the anti-adhesive agent used in the surface treatment of the base material silk cloth is improperly selected, or the proportion of the anti-adhesive agent is imprope...
