Abstract

The invention discloses an anti-bacterial and acid-alkali-resistant medical material and a preparation method thereof. The medical material is prepared from main ingredients including pharmaceutical grade polyvinyl alcohol, polypropylene resin, poly-3-hydroxybutyrate and polyethylene glycol fatty acid ester mixed with pentaerythritol oleate, octenyl succinic acid modified starch, citrate, N-butylcyanoacrylate, sulfanilamide, sodium citrate, polyactic acid fibers, aluminium silicate ceramic fibers, magnesium carbonate, gaseous-phase white carbon black, malic acid, a dispersing agent and a stabilizer by mixing, stirring, high-temperature sintering, grinding, high-pressure calcination, acid leaching, ultrasonic dispersion, screw extrusion, injection molding treatment and the like. The anti-bacterial and acid-alkali-resistant medical material has an excellent anti-bacterial property and acid and alkali resistance, can meet requirements of the industry and has better application prospect.

Description

technical field [0001] The invention relates to the technical field of biomedical materials, in particular to an antibacterial, acid and alkali resistant medical material and a preparation method thereof. Background technique [0002] Biomedical materials are materials used to diagnose, treat, repair or replace damaged tissues and organs of living organisms or enhance their functions. It is the basis for the study of artificial organs and medical devices, and has become an important branch of contemporary materials science. The application of biomedical materials has greatly promoted the rapid development of medical diagnosis and treatment technology. So far, more than a thousand kinds of biomaterials have been studied in detail, and dozens of them are widely used in clinical medicine, involving various fields of materials science. At present, the focus of research on biomedical materials is to find biomedical materials with better tissue compatibility, degradability, corro...
