Problems solved by technology

The film materials commonly used now include polytetrafluoroethylene, polyethylene, polypropylene, polychlorinated p-xylene, etc. The production process is complicated, the efficiency is low, and the cost is high. Due to the thickness of the film layer, it is easy to cause the film layer to fall off and reduce the rubber stopper. The original self-sealing property, and it is difficult to achieve uniform film formation on the surface of rubber stoppers with complex shapes

Abstract

The invention relates to a fluorocarbon film rubber plug and a preparation method thereof. The fluorocarbon film rubber plug comprises a rubber plug body, part or all of the surface of the rubber plug body is covered with a fluorocarbon polymer film, and the rubber plug body and the fluorocarbon polymer film are physically and / or chemically bonded and integrated into a whole without any adhesive between of both. The fluorocarbon polymer film is obtained by being deposited on the surface of an ordinary rubber plug by adopting a method of plasma chemical vapor deposition of reaction gas glow discharge. By strongly combining the ordinary rubber plug with the fluorocarbon polymer film with the advantages of high hydrophobicity, strong chemical inertness, uniform and compact structure and precise and controllable film thickness, the invention not only can obviously improve compatibility with contacted medicines, but also can effectively avoid the adhesion phenomenon of the rubber plug and easily remove surface contamination and preserve the original elasticity and tightness of the rubber plug in order to significantly improve product quality of the ordinary rubber plug and further expand application scope of the ordinary rubber plug.

Description

technical field [0001] The invention relates to the field of medical encapsulation materials, in particular to a medical fluorocarbon film rubber stopper and a preparation method thereof. Background technique [0002] Rubber stoppers for medicine are the main sealing and exporting parts used to encapsulate various bottled medicines such as antibiotics and infusion medicines. During use and storage, they will inevitably come into direct contact with the medicines. decisive role. Existing studies have shown that when the rubber stopper is in contact with the injection, the rubber stopper may absorb active ingredients, antibacterial preservatives or other substances in the injection, and even cause a chemical reaction to cause the drug to fail; one or more components in the rubber stopper It may also be leached into the injection solution to make it cloudy, produce toxicity or pyrogen, affect the chemical and physical stability of the preparation, and sometimes produce serious...
