Embodiment 1

[0038] Weigh 100 g of ZnO, 96 g of P 2 o 5 , 20 g Na 2 O, mix evenly in a high-speed mixer, then place in a ceramic crucible, and keep the temperature in a high-temperature furnace at 600°C for 1 hour to form a melt-like liquid, then slowly pour the melt into cold water to form a preliminary crushed antibacterial glass , and then take out the antibacterial glass and dry it in an oven at 100°C for 30 minutes to make it fully dry. Then utilize jet mill to pulverize it into antibacterial glass powder with average particle size less than 20 microns. The composition of antibacterial glass powder was analyzed by X-ray energy spectrum analyzer (EDX), and its composition was calculated according to the oxide component: ZnO 51wt%, P 2 o 5 39wt%,Na 2 O10wt%.

Embodiment 2

[0040] Weigh 373 grams of Zn(NO 3 ) 2 ·6H 2 O, 0.03 g AgNO3, 65 g P 2 o 5 , 55 g KH 2 PO 4 , mixed evenly in a high-speed mixer, then placed in a ceramic crucible, kept in a high-temperature furnace at 700°C for 45 minutes to form a melt-like liquid, and then slowly poured the melt into cold water to form a preliminary crushed antibacterial glass, Then take out the antibacterial glass and dry it in an oven at 100°C for 30 minutes to make it fully dry. Then utilize jet mill to pulverize it into antibacterial glass powder with average particle size less than 20 microns. The composition of antibacterial glass powder is analyzed by energy spectrum analysis, and its composition is calculated according to the oxide component: ZnO 51wt%, Ag 2 O0.01wt%,P 2 o 5 39.5wt%, K 2 O 9.49wt%.

Embodiment 3

[0042] Weigh 120 g of ZnC 2 o 4 .2H 2 O, 50 g P 2 o 5 , 31 g Na 2 CO 3 , mixed evenly in a high-speed mixer, then placed in a ceramic crucible, kept in a high-temperature furnace at 800°C for 30 minutes to form a melt-like liquid, and then slowly poured the melt into cold water to form a preliminary crushed antibacterial glass, Then take out the antibacterial glass and dry it in an oven at 100°C for 30 minutes to make it fully dry. Then utilize jet mill to pulverize it into antibacterial glass powder with average particle size less than 10 microns. The composition of antibacterial glass powder is analyzed by energy spectrum analysis, and its composition is calculated according to the oxide component: ZnO 52wt%, P 2O 5 30wt%,Na 2 O18wt%.

Abstract

The present invention discloses an antibacterial glass composition and a preparation method thereof. The antibacterial glass composition comprises 50-60 wt% of ZnO, preferably 50-55wt%, and 0-0.09 wt% of Ag2O, preferably 0.01-0.05 wt%, and can further comprise 30-40 wt% of P2O5, preferably 35-40 wt%, and 6-18 wt% of Na2O or K2O, preferably 8-10 wt%. The preparation method comprises: carrying out high temperature melting and cooling on the components or hydroxides and salts corresponding to the components to prepare the antibacterial glass composition. The antibacterial glass composition has characteristics of excellent heat resistance, discoloration resistance and efficient antibacterial activity, and can be used in a plurality fields.

Description

technical field [0001] The invention relates to the field of antibacterial glass, in particular to an antibacterial glass composition and a preparation method thereof. Background technique [0002] In recent years, with the improvement of people's living standards, the demand for antibacterial products is increasing. As the main element of antibacterial products, antibacterial agents are mainly divided into organic and inorganic antibacterial agents. Due to its higher safety and heat resistance, the market share of inorganic antibacterial agents has been increasing in recent years, especially in developed countries such as Japan, Europe and the United States, where inorganic antibacterial agents have developed rapidly. [0003] Inorganic antibacterial agents usually refer to silver and zinc as the main antibacterial components, which are loaded on different carriers, including zeolite, glass, zirconium phosphate, hydroxyapatite, etc. Among them, antibacterial glass has exce...
