Embodiment

[0021] The first step is to flatten the elastomer film 3 and the high polymer film 1 together, as shown in Figure 2. The elastomer surface can be a flat surface or a corrugated surface with grooves. The difference lies in the grooves. The corrugated surface film is conducive to exhaust, and the production equipment of flat film does not need to be modified, and the production process is simpler. No matter what kind of elastomer film, you can choose open mill, three-roll calender and four-roll calender to complete. Generally, it is between 40°C and 180°C, depending on the production equipment.

[0022] The second step is to put the flat film with film 3 into a vulcanizing machine with a film core 4, as shown in Figure 3. The vulcanizing machine can be a vacuum vulcanizing machine, an ordinary compression vulcanizing machine, or an injection vulcanizing machine. , Vulcanization temperature: 120℃-200℃, pressure 8-20Mpa. The vulcanization time can be determined according to the vulcan...

Abstract

Disclosed is a making method of a local diaphragm rubber stopper, pertaining to the technical field of rubber stopper coating. The main process of the method is that: splice an elastic film with a high polymer film orderly; put the filmed film to a vulcanizing machine for vulcanization; incise the high polymer film at the neck of the rubber stopper circularly, which only cut the high polymer film and does not damage the basal body of the elastic body; heat or cool the incised product and then remove the unnecessary part of the high polymer film at the crest of the rubber stopper under mechanical force, in this way the local diaphragm rubber stopper can be attained. With the making method of the local diaphragm rubber stopper of the invention, it is easy to coat the external local parts of the rubber stopper. The invention has the advantages of simple processing and high efficiency.

Description

Technical field [0001] The invention relates to a production method of a partial diaphragm bottle stopper. Background technique [0002] Rubber stoppers for medical containers are different from general-purpose rubber stoppers. They must meet the requirements of the prescribed standards. Moreover, the requirements for the reliability of medical containers are increasing. In response to this requirement, various types of rubber stoppers have come out. Among them, a rubber stopper covered with a layer of fluoropolymer is recommended and used, because the fluoropolymer material does not contaminate the drug in the container. In addition, the fluoropolymer can prevent the rubber compound from being damaged due to its extreme inertness and excellent chemical stability. Dissolve into the medicine. [0003] However, if the surface of the rubber stopper is completely covered with this polymer film, it will cause the leaching or leakage of the liquid medicine due to the formation of capil...
