Problems solved by technology

[0002] Polymer materials are a kind of material commonly used in medical materials nowadays. According to different sources, they can be divided into natural, semi-synthetic (modified natural polymer materials) and synthetic polymer materials. Medical polymer materials are due to their special use. It has been widely used in the medical field, but the traditional medical polymer materials are relatively poor in elasticity and flexibility. Therefore, we propose a preparation method of highly elastic medical polymer materials

Abstract

The invention discloses a preparation method of a high-elasticity medical polymer material in the technical field of medical materials. The high-elasticity medical polymer material comprises the following components in parts by weight: 25 to 45 parts of silicone rubber, 15 to 35 parts of coarse whiting powder, 25 to 30 parts of trioctyl trimellitate, 20 to 26 parts of polyvinyl chloride resin, 18to 25 parts of a polymer modifier, 21 to 27 parts of a heat stabilizer, 23 to 27 parts of polylactic acid and 22 to 32 parts of a light stabilizer. The preparation method of the high-elasticity medical polymer is simple, by adding silicone rubber and polylactic acid, the elasticity and flexibility of the whole polymer are improved, after the silicone rubber is processed according to process requirements, a rubber-state elastomer with certain strength and elongation is prepared, the rubber-state elastomer is free of toxic and side reactions and easy to process, the polylactic acid is non-toxic,non-irritant, good in biocompatibility, capable of being biologically decomposed and absorbed, high in strength and high in plasticity, and the elasticity of medical macromolecules can be enhanced byadding materials.
