Medicinal compound polyisoprene and epoxy resin copolymerization gasket

Abstract

Disclosed is a medicinal compound polyisoprene and epoxy resin copolymerization gasket. The medicinal compound polyisoprene and epoxy resin 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 E-42 epoxy resin, 89-99 parts of phenolic aldehyde-nitrile rubber buna copolymer, 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 a 50% sodium hydroxide 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, 400-450 parts of chrysanthemum water, 10-20 parts of floral water and 30-50 flower and plant roots. The medicinal compound polyisoprene and epoxy resin 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 medicinal rubber pads, in particular to a medicinal synthetic polyisoprene and epoxy resin copolymer pad. Background technique: [0002] With the development of society, there are more and more types of rubber products used in the medical and health fields, such as various medicine bottle rubber stoppers, sterile syringe pistons, injection sealant seals, hoses, catheters, medical air cushions, and sterilization Rubber medical gloves, baby pacifiers, blood transfusion hoses, etc. Ideal medical rubber products not only need to have good physical properties, but also must be non-toxic and chemically inert. In particular, internal rubber products should have the characteristics of not causing disease, not damaging adjacent tissues, not causing allergies, and good aging properties. [0003] Under the conditions of high temperature and high pressure, the vulcanization system of traditional m...

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
