Problems solved by technology

Generally, an organic solvent needs to be added in the process of coating the base of the bottle stopper. If the organic solvent cannot be completely volatilized, it may have a certain impact on the drug. After the organic solvent evaporates, the combination of the inert diaphragm and the base of the cork is not very dense.

Abstract

The invention discloses a method to produce the diaphragm bottle cork for medicine using the inert diaphragm and the rubber. It puts the diaphragm and the bottle cork into the vulcanizer to make them form a whole because of the cross linking reaction of the active free radical on the surface of the diaphragm layer and the active group on the rubber surface. The process does not need the organic solvent so it avoids the organic solvent pollution to the bottle cork.

Description

technical field [0001] The invention relates to a method for preparing a medicinal septum bottle stopper, in particular to a method for obtaining a medicinal diaphragm cork by vulcanization. Background technique [0002] Diaphragm bottle stoppers are widely used in the medical field. After attaching an inert diaphragm to the outside of the bottle stopper, the rubber base of the bottle stopper is isolated from the bottled medicine, which can reduce the pollution of the medicine in the bottle. Generally, an organic solvent needs to be added in the process of coating the base of the bottle stopper. If the organic solvent cannot be completely volatilized, it may have a certain impact on the drug. After the organic solvent volatilizes, the combination of the inert diaphragm and the base of the cork is not very dense. Contents of the invention [0003] The purpose of the present invention is to provide a kind of method that adopts inert diaphragm and rubber to prepare medicinal ...
