Abstract

The invention discloses a magnesium borate crystal whisker super induced biomaterial and preparation method thereof, the biomaterial uses polypropylene, poly glycolic acid, and methyl benzoate as the main component, through adding poly-3-hydroxybutyric acid, trihydroxymethyl aminomethane, 2-thiol benzimidazole, di-amino-maleic acid, elhylene diamine tetraacetic acid, dodecyl trimethyl ammonium iodide, epoxidized soybean oil, naphthylacetic acid sodium, magnesium borate whisker, montmorillonite powder, light mass calcium carbonate, dispersant, and stabilizer, supplemented with mixing and stirring, high temperature sintering, crushing, high pressure calcinations, acid soaking, ultrasound dispersing, screw rod extruding, injection treatment and other processes, is prepared fully. The biomaterial super induced with magnesium borate crystal whisker has high low temperature shock resistance ability and high anti-aging property, can satisfy the requirements of each branch, and has relatively good application prospect.

Description

technical field [0001] The invention relates to the technical field of biomedical materials, in particular to a biomaterial added with magnesium borate whiskers 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, corrosion resis...
