Disclosed are a medical material and a preparation method therefor. The preparation method comprises the following steps: S1: adding a nano montmorillonite into a solution of a silane coupling agent, followed by stirring, rinsing, and drying to obtain a modified nano montmorillonite; and S2: mixing a thermoplastic elastomer with the modified nano montmorillonite to obtain the medical material. The medical material prepared according to the present invention improves the modulus, breaking strength and flexural modulus of the thermoplastic elastomer, and broadens the application of the thermoplastic elastomer in the field of high-end minimally invasive interventional medical products; simplifies a production process; and increases productivity. |
