Medicinal compound polyisoprene and hide glue copolymerization gasket

Abstract

Disclosed is a medicinal compound polyisoprene and hide glue copolymerization gasket. The medicinal compound polyisoprene and hide glue copolymerization gasket 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 hide glue, 89-99 parts of phenol-nitrile butadiene rubber copolymer, 66-75 parts of hydrochloric acid, 10-15 parts of quadrol, 100-120 parts of soybean protein, 5-7 parts of urea, 15-20 parts of a 50% sodium hydroxide water solution, 40-50 parts of whitewash, 30-40 parts of sodium silicate, 2-5 parts of thiourea, 1-2 parts of carbon tetrachloride, 2-5 parts of chlorophenasic acid, 400-500 parts of a 40% nitric acid water solution, 10-20 parts of floral water, and 30-50 flower and plant roots. The medicinal compound polyisoprene and hide glue copolymerization gasket has the advantages that the gasket can directly make contact with drugs, an inner cover of a combination cover can be omitted, the puncture force and chip falling probability are decreased, and on the other hand, the cover assembling cost is lowered for a pharmaceutical factory.

Description

Technical field: [0001] The invention relates to the technical field of manufacturing methods of medical rubber pads, in particular to a pharmaceutical synthetic polyisoprene and hide glue copolymerized gasket. 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 pre...

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
