Problems solved by technology

However, due to the structural defects of polyvinyl chloride resin, the chlorine atoms in its molecular structure are easily affected by external conditions, and HCl molecules are easily removed under conditions such as high temperature and light, thereby forming a double bond structure, and the removed HCl molecules will in turn catalyze the thermal decomposition of polyvinyl chloride, aggravating the formation of a double bond structure, and the existence of a double bond structure will lead to problems such as material performance degradation and discoloration
In addition, the above-mentioned polyvinyl chloride molecule has a certain polarity due to the presence of a relatively high content of chlorine atoms. The molecular structure is rigid at room temperature and is not easy to move, thus showing the characteristics of brittleness, hardness and poor toughness. The further application of polyvinyl chloride

Abstract

The invention discloses a preparation method and application of a medical composite packaging material. The method is characterized in that polyvinyl acetate and coconut oil fatty acid monoethanolamide are fed into a reaction kettle for high-temperature stirring to obtain a primary mixture; the primary mixture, polyglycerol ricinoleate ester and polyethylene glycol oleate are jointly added into anultrasonic disperser; absolute ethyl alcohol is added; ultrasonic treatment and heating heat insulation are performed to obtain a secondary mixture; then, zinc borate is modified; finally, the secondary mixture and the modified zinc borate are jointly fed into the reaction kettle; nitrile rubber and 2-thiol group benzimidazole are added; under the condition of inert gas protection, high-temperature stirring is performed; then, temperature reduction is performed; a flexibilizer and a stabilizer are added; stirring is performed to obtain an ultimate mixture; then, the ultimate mixture is fed into a double screw extruder for fused extruding, cutting, packaging and sterilization; after the cooling, a finished product composite material is obtained. The prepared medical composite packaging material has the advantages that the self mechanical intensity is high; the steam sterilization can be endured; good application prospects are realized on the medical appliance packaging.

Description

technical field [0001] The invention relates to the technical field of medical materials, in particular to a preparation method and application of a medical composite packaging material. Background technique [0002] Medical device packaging materials ensure that patients receive treatment in a safe environment, which can effectively avoid nosocomial infections during treatment. Commonly used medical device packaging materials should be sealed and reliable, can be used for sterilization, and have bacteria resistance. At present, the commonly used medical device packaging material on the market is polyvinyl chloride resin. Due to its good biocompatibility, excellent biological inertness, antibacterial ability, high transparency and good mechanical properties, coupled with its low cost, Polyvinyl chloride resin materials occupy a major market share in the medical materials market. However, due to the structural defects of polyvinyl chloride resin, the chlorine atoms in its m...
