Embodiment 1

[0019] A silver-loaded hydroxyapatite, in which silver is loaded on the hydroxyapatite.

Embodiment 2

[0021] A preparation method of silver-loaded hydroxyapatite, which consists of the following steps: according to the mass ratio of 1:30, AgNO with a mass concentration of 8% 3 The aqueous solution is mixed with hydroxyapatite, kept away from light, stirred at 25°C for 25 hours, ion-exchanged, filtered, dried, and calcined at 800°C for 6 hours to produce a silver-loaded hydroxyapatite.

[0022] Hydroxyapatite was prepared from Example 5.

Embodiment 3

[0024] A preparation method of silver-loaded hydroxyapatite, comprising the following steps: according to the mass ratio of 1:10, the mass concentration is 25% of AgNO 3 The aqueous solution is mixed with hydroxyapatite, stirred at 20°C for 20h in the dark, ion exchanged, filtered, dried, and calcined at 1000°C for 3h to produce a silver-loaded hydroxyapatite.

[0025] Hydroxyapatite was prepared from Example 5.

Abstract

The invention discloses an AgxCa10-x(PO4)6(OH)2 and a preparation method; the AgxCa10-x(PO4)6(OH)2 is the hydroxyapatite loaded with silver irons; the preparation method has the following steps: based on the mass ratio of 1:30-10, the AgNO3 aqueous solution with the mass concentration of 8%-25% is mixed with hydroxyapatite and stirred in the dark at 15-30 DEG C for 15-30 hours, and then treated with ion exchange reaction and filtered; the solid is dried and calcined at 800-1000 DEG C to prepare the AgxCa10-x(PO4)6(OH)2. The vector matrix hydroxyapatite molecues of the AgxCa10-x(PO4)6(OH)2 contain hydroxy groups which can produce force with cellulose molecules to improve the combination fastness between antibacterial agent and cotton fiber; after the ordinary cotton fabric is antimicrobially treated with AgxCa10-x(PO4)6(OH)2, the cotton fabric with broad antimicrobial spectrum, good human body compatibility, high safety and good washing fastness can be obtained.

Description

technical field [0001] The invention relates to a hydroxyapatite and a preparation method, in particular to a silver-loaded hydroxyapatite and a preparation method. Background technique [0002] The research on antibacterial materials in our country was mainly in the mid-1990s. Except for the application in a few fields such as coating anticorrosion, other fields are almost completely blank. In recent years, my country's antibacterial material industry has developed rapidly. A large number of enterprises, universities, and scientific research institutions have cooperated closely in the industrialization and application of natural antibacterial agents, inorganic antibacterial agents, organic antibacterial agents, photocatalytic antibacterial agents and antibacterial materials. Development and other fields have developed rapidly. At present, the development and application of antibacterial materials in my country has made great progress, and a new antibacterial industry has in...
