Embodiment 1

[0052] This embodiment provides a medical composite material with a structure such as figure 1 (1 is the first polymer thread, 2 is the second polymer, and 3 is the bioactive glass fiber), the preparation method is as follows:

[0053] Add 35 parts by mass of bioactive phosphate glass fiber (bioactive glass fiber), 5 parts by mass of the second polymer PCL polymer, 100 parts by mass of acetone, and 40 parts by mass of zirconium beads into the dispersion tank. After dispersing and shearing for 2 hours, filter the zirconium beads to obtain solution A; put the first polymer L-polylactic acid thread into solution A to infiltrate, dry with hot air, and then pull it into a conical device for pultrusion (pultrusion The line speed is 0.11m / min). In the drawn melt (65°C), the mass ratio of bioactive phosphate glass fiber to PCL was 5:3. The pultruded and cooled material filaments were cut into 10 cm lengths to obtain composite material monomers. Align 1000 obtained composite materia...

Description

technical field [0001] The invention belongs to the field of medical materials, in particular to a medical composite material and its preparation method and application, in particular to a medical composite material with high bending strength and high elastic modulus, its preparation method and application. Background technique [0002] Bioactive glass (Bioactive glass, BAG) is a kind of material that can repair, replace and regenerate body tissues, and can form a bond between tissues and materials. At present, bioactive glass has been successfully used in the treatment and restoration of bone injuries and dental diseases. [0003] Bioactive glass was discovered by Hench in 1969, made of SiO 2 , Na 2 O, CaO and P 2 o 5 Silicate glass composed of basic components. In 1984, bioactive glass was successfully used in the human body as a middle ear prosthesis. With the deepening of people's understanding of bioactive glass and the development of new types of active glass, si...
