Example Embodiment

[0012] Examples:

[0013] The first step is to put elastomer film A in a vulcanizing machine. Elastomer film A uses halogenated butyl rubber. The vulcanizing machine can be a vacuum vulcanizing machine, an ordinary compression vulcanizing machine, or an injection vulcanizing machine. The vulcanization temperature: 120℃-200℃, pressure 4-20Mpa. The vulcanization time is 3-8 minutes, and the cured product is the part that is in contact with the drug, namely the neck 2.

[0014] The second step is to remove the rubber edge on the plug neck 2.

[0015] The third step is to put the stopper neck 2 in the vulcanizing machine, and place the elastomer film B in the vulcanizing machine at the same time. The elastomer film B uses isoprene rubber, ternary propylene rubber, styrene butadiene rubber, and nitrile rubber. Or neoprene, the vulcanizing machine can be a vacuum vulcanizing machine, a common compression vulcanizing machine, or an injection vulcanizing machine, and the crown plug 1 is o...

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 [0001] The invention relates to a production method of a rubber bottle stopper used for a medical container, in particular to a medical rubber bottle stopper obtained through compound molding technology using two types of rubber with different properties. Background technique [0002] At present, the common medical rubber bottle stoppers in China are all made of one kind of rubber. Due to the high requirements on the stability of rubber and other safety indicators when producing medical products, the production cost of bottle stoppers is relatively high. Contents of the invention [0003] The object of the present invention is to provide a bottle that is cross-linked with rubbers with different properties on the premise that the part that is in contact with the drug, that is, the neck, and the part that is not in contact with the drug, that is, the crown, meet the performance indicators of the relevant standards. The invention relates to a production method...
