Abstract

The invention provides a medical transparent polypropylene material capable of resisting electron beam irradiation. The medical transparent polypropylene material capable of resisting electron beam irradiation is prepared from the following components in parts by weight: 100 parts of a transparent polypropylene base material, 2 to 10 parts of irradiation-resistant masterbatch and 0.2 to 0.5 part of a heat stabilizer, wherein the transparent polypropylene material is a polypropylene random copolymer base material, the light transmittance is 85 to 86 percent and the melt index is 2 to 6 g / 10 min; the irradiation-resistant masterbatch is prepared by compounding a hindered amine stabilizer and a UV shielding agent and then by using PP; the heat stabilizer is one or more of AE1010 and 168. Thetransparent polypropylene material provided by the invention has the advantages of capability of effectively preventing yellowing phenomenon, high transparency, avoidance of color change, and the like.

Description

technical field [0001] The invention belongs to the technical field of medical material preparation, and in particular relates to a medical transparent polypropylene material resistant to electron beam irradiation and a preparation method thereof. Background technique [0002] Medical devices are widely sterilized with ethylene oxide. The advantage of this method is that it can kill all microorganisms. However, ethylene oxide is a highly flammable, petroleum-based gas, mutagenic and carcinogenic. It is not only used in production and processing There are great potential safety hazards in the process, and there are also disadvantages such as polluting the environment, residual chemical substances harmful to the human body, and long cycle times. The use of electron beam irradiation to sterilize medical devices has the advantages of no pollution, no residue, and short cycle. At present, developed countries in the world have widely used radiation to sterilize medical devices, an...
