Embodiment 1
[0025] Weigh 10.00 grams of short rod-shaped nano-hydroxyapatite, and 50.00 grams of barium strontium boron glass powder, and 40.00 grams of borosilicate glass powder, and mix the above three components uniformly by mechanical stirring to make a total weight of 100.00 grams of nano-inorganic powders containing multiple components are set aside; the radial width of the short rod-shaped nano-hydroxyapatite involved is less than 100 nanometers, and its aspect ratio is distributed between 2 and 6. Short rod-shaped nano-hydroxyapatite materials with limited width and limited aspect ratio can be used.
[0026] 2.50 grams of medical-grade silane coupling agent KH-570 were hydrolyzed under the action of acetic acid, and 40 milliliters of hydroalcoholic solution was added. The pre-mixed nano-inorganic powder containing multiple components is dispersed in ultrasonic waves, and then reacted at 50°C for 24 hours, moved to an oven, and dried at 80°C for 10 hours, then, use the water alcoho...
Embodiment 2
[0029] Weigh 80.00 grams of short rod-shaped nano-hydroxyapatite, and 20.00 grams of barium strontium boron glass powder, and mix the above three components uniformly by mechanical stirring to make a nano Inorganic powder, ready for use; wherein the radial width of the short rod-shaped nano-hydroxyapatite involved is less than 100 nanometers, and its aspect ratio is distributed between 2 and 6, and those that meet the radial width limit and aspect ratio limit Short rod-shaped nano-hydroxyapatite materials can be used.
[0030] 2.00 grams of medical grade silane coupling agent KH-570 was hydrolyzed under the action of acetic acid, and 400 milliliters of hydroalcoholic solution was added. The premixed nano-inorganic powder containing multiple components is dispersed in ultrasonic waves, then reacted at 100°C for 2 hours, moved to an oven, and dried at 80°C for 2 hours, then, use the water alcohol The solution is washed, then dried at 80°C for 2 hours, and then heated to 100°C f...
Embodiment 3
[0033] Weigh 45.00 grams of short rod-shaped nano-hydroxyapatite, and 25.00 grams of barium-strontium-boron glass powder, and 10.00 grams of strontium glass powder, and 10.00 grams of boron-aluminum glass powder, and 10.00 grams of commercially available barium-aluminum glass powder , the above multiple components are uniformly mixed by means of mechanical stirring to make a nano-inorganic powder with a total weight of 100.00 grams containing multiple components for use; wherein the radial width of the short rod-shaped nano-hydroxyapatite involved is less than 100 nanometers, its aspect ratio is distributed between 2 and 6, and any short rod-shaped nano-hydroxyapatite material that meets the above-mentioned radial width limitation and aspect ratio limitation can be used.
[0034] 10.00 grams of medical grade silane coupling agent KH-570 was hydrolyzed under the action of acetic acid, and 200 milliliters of hydroalcoholic solution was added. The premixed nano-inorganic powder c...
