Abstract
The invention relates to a method for producing a medical rubber bottle cork made of dual composite materials, belonging to the technical field of medical bottle corks. A cap plug and a neck plug are made of different types of rubbers and the composite rubber is obtained by a sulfidation process. In the invention, the part that touches the medical liquid in the bottle adopts highly stable rubber, and the part that dose not touch the medical liquid adopts ordinary medical rubber, thereby reducing the production cost and improving the economic benefit on the premise of ensuring safety.
Description
Technical field
The present invention relates to a kind of production method that is used for the bottle closure of rubber of medical container, the glue kind of two kinds of different attributes of particularly a kind of employing, the pharmaceutical bottle closure of rubber that the process composite forming technology obtains.
Background technology
At present domestic common pharmaceutical bottle closure of rubber is a kind of rubber production, owing to the safety indexs such as stability of rubber are required very highly when production relates to pharmaceutical product, causes the production cost of bottle stopper higher.
Summary of the invention
The purpose of this invention is to provide a kind of and medicine contact portion promptly fills in neck and non-ly promptly fills in hat under the prerequisite of the performance indications that satisfy relevant criterion with the medicine contact portion, the crosslinked production method that obtains the medical rubber bottle cork made of dual composite material of bottle stopper of glue kind of plug neck and plug hat employing different attribute.
The object of the present invention is achieved like this: a kind of production method of medical rubber bottle cork made of dual composite material, A places vulcanizer to vulcanize with the elastomer film, curing temperature: 120 ℃-200 ℃, pressure 4-20Mpa, cure time 3-8 minute, the product that vulcanizates was promptly filled in neck with the medicine contact portion exactly;
The plug neck is separated with the glue limit;
The plug neck inserted put into vulcanizer once more, elastomer film B places vulcanizer simultaneously, obtains hat plug (1) by elastic film B, curing temperature: 120 ℃-200 ℃, pressure 4-20Mpa, cure time 3-8 minute, the product that vulcanizates was exactly a medical rubber bottle cork made of dual composite material.
Elastomer film A adopts halogenated butyl rubber.
Elastomer film B adopts isoprene rubber, ternary third rubber, butadiene-styrene rubber, acrylonitrile-butadiene rubber or neoprene.
The production method of medical rubber bottle cork made of dual composite material provided by the present invention, promptly fill in neck with the medicine contact portion and adopt the inertia and the chemical stability of thing rubber can prevent that the rubber compound composition is dissolved in the medicament, meet compatibility specification requirement with medicine; Non-and medicine contact portion is promptly filled in the requirement that hat can satisfy the performance indications of relevant criterion, and it is crosslinked that plug neck and plug hat carry out clean moulding, like this, reduced production cost under the prerequisite of assurance safe handling.
Description of drawings
Concrete structure of the present invention is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Embodiment:
The first step is that elastomer film A is placed vulcanizer, and elastomer film A adopts halogenated butyl rubber, and vulcanizer can be to vacuumize vulcanizer, it also can be common molded vulcanization machine, perhaps inject vulcanizer, curing temperature: 120 ℃-200 ℃, pressure 4-20Mpa.Cure time 3-8 minute, the product that vulcanizates was promptly filled in neck 2 with the medicine contact portion exactly.
Second step was that the glue limit on the plug neck 2 is removed.
The 3rd step was that plug neck 2 is inserted in the vulcanizer, with elastomer film B, place vulcanizer simultaneously, elastomer film B adopts isoprene rubber, ternary third rubber, butadiene-styrene rubber, acrylonitrile-butadiene rubber or neoprene, vulcanizer can be to vacuumize vulcanizer, also can be common molded vulcanization machine, perhaps inject vulcanizer, obtain hat plug 1 by elastic film B.Curing temperature: 120 ℃-200 ℃, pressure 4-20Mpa.Cure time 3-8 minute, the product that vulcanizates was exactly a medical rubber bottle cork made of dual composite material.
Claims (3)
1, a kind of production method of medical rubber bottle cork made of dual composite material, it is characterized in that: A places vulcanizer to vulcanize with the elastomer film, curing temperature: 120 ℃-200 ℃, pressure 4-20Mpa, cure time 3-8 minute, the product that vulcanizates was promptly filled in neck (2) with the medicine contact portion exactly;
The plug neck is separated with the glue limit;
The plug neck inserted put into vulcanizer once more, elastomer film B places vulcanizer simultaneously, obtains hat plug (1) by elastic film B, curing temperature: 120 ℃-200 ℃, pressure 4-20Mpa, cure time 3-8 minute, the product that vulcanizates was exactly a medical rubber bottle cork made of dual composite material.
2, the production method of medical rubber bottle cork made of dual composite material according to claim 1 is characterized in that: elastomer film A adopts halogenated butyl rubber.
