Halogenated butyl rubber membrane covering rubber plug for injection

Abstract

A halogenated butyl rubber membrane covering rubber plug for injection is prepared from 60-70 parts of brominated butyl rubber, 30-40 parts of calcined kaolin, 3-5 parts of zinc oxide, 89-99 parts of epoxy resin E-42, 89-99 parts of phenol-nitrile butadiene rubber copolymers, 66-75 parts of acetone, 10-15 parts of ethidene diamine, 100-120 parts of soybean protein, 5-7 parts of turpentine, 15-20 parts of 50% sodium hydroxide aqueous solution, 40-50 parts of whitewash, 400-450 parts of chrysanthemum water, 10-20 parts of floral water, 30-50 parts of flower and plant roots and stems, 5-10 parts of ginseng, 5-10 parts of atractylodes macrocephala koidz, 5-10 parts of raw rice sprouts, 50-60 parts of water, 5-10 parts of scorched hawthorn fruit, 5-10 parts of medicated leaven, 5-7 parts of radix polygonati officinalis, 9-12 parts of rhizoma arisasmatis, 15-18 parts of calamendiol, 15-18 parts of wood bits and 100-120 parts of soycheese water. The rubber plug has the advantages that the rubber plug prepared through the process can make direct contact with medicine, an inner cover of a combined cover can be omitted, the penetration force and the chipping falling rate are decreased, and cover assembling cost is reduced for pharmaceutical factories as well.

Description

Technical field: [0001] The invention relates to the technical field of pharmaceutical rubber manufacturing methods, in particular to a halogenated butyl rubber-coated rubber stopper for injection. Background technique: [0002] With the development of society, there are more and more types of rubber products used in the medical and health field, such as rubber stoppers for various pharmaceutical bottles, pistons for sterile syringes, sealing rubber seals for injections, hoses, catheters, medical air cushions, sterilization Rubber medical gloves, baby pacifiers, blood transfusion tubes, etc. Ideal medical rubber products not only need to have good physical properties, but also must be non-toxic and chemically inert. In particular, rubber products in the body should have the characteristics of not causing disease, not damaging adjacent tissues, not causing allergies, and having good aging properties. [0003] Under the conditions of high temperature and high pressure, the vu...

AI Technical Summary

Problems solved by technology

[0003] Under the conditions of high temperature and high pressure, traditional medical rubber products tend to produce exudates and volatiles that pollute the human body and pharmaceuticals in their vulcanization system, making it difficult to prepare medical rubber products that meet the highest quality standards for pharmaceuticals

Existing medical rubber products and preparation methods thereof have complicated process, poor product environmental protection, weak use safety, and low service life
