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

Abstract

A drug packaging rubber plug prepared from casein-soybean glue is mainly prepared from auxiliary rubber, casein-soybean glue and a mixed solution which are mixed together, wherein the mixed solution is added into the auxiliary rubber and the casein-soybean glue respectively, and the specific weight of the mixed solution added into the auxiliary rubber and the mixed solution added into the casein-soybean glue is 1: 1.36; the mixtures are stirred for 10 min; 20 percent of a casein-soybean glue and mixed solution mixed glue is taken and added into the auxiliary rubber, stirring is performed, after 3 min, the rest 80 percent of the casein-soybean glue and mixed solution mixed glue is added, and stirring is continually performed for 2 min to obtain a colloid; the colloid is cooled for 1 day in air at 15 DEG C, and slicing is performed to obtain the drug packaging rubber plug. The drug packaging rubber plug has the following beneficial effects: the formula is novel in design, the raw materials can be easily obtained, and a rubber product prepared by the formula is relatively high in chemical stability, nonirritant, high in security, heat-proof, anti-aging and favorable in mechanical property and can be made into drug packaging rubber plugs of different specifications.

Description

Technical field: [0001] The invention relates to the technical field of medical rubber production, in particular to a medicine packaging rubber plug made of soybean protein glue. 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 vulcanization system ...
