Embodiment 1

[0035] In terms of weight percentage, mix 45% of Longquan celadon glaze, 35% of nano-silicon oxide and 20% of silver phosphate, mix evenly, grind finely, and pass through a 300-mesh sieve to obtain the Longquan celadon antibacterial agent.

[0036] The chemical composition of Longquan celadon glaze in this embodiment is:

[0037] SiO 2 69.95%

[0038] K 2 O 5.2%

[0039] Na 2 O 0.96%

[0040] Al 2 o 3 14.16%

[0041] Fe 2 o 3 1.95%

[0042] CaO 7.2%

[0043] MgO 0.34%

[0044] TiO 2 0.24%

[0045] Mix 28% of Longquan celadon antibacterial agent prepared above with 72% of traditional celadon underglaze to make antibacterial glaze dry agent. Dissolve the antibacterial glaze drying agent with water and ball mill it into glaze slurry, immerse the celadon carcass in the antibacterial glaze, dry it and then fire it at 1250-1350 degrees Celsius.

[0046] The antibacterial glaze obtained in this embodiment has a bactericidal rate of 95...

Embodiment 2

[0048] In terms of weight percentage, mix 47% of Longquan celadon glaze, 33% of nano-silicon oxide and 20% of silver phosphate, mix evenly, grind finely, and pass through a 300-mesh sieve to obtain the Longquan celadon antibacterial agent.

[0049] The chemical composition of Longquan celadon glaze in this embodiment is:

[0050] SiO 2 68.72%

[0051] K 2 O 5.1%

[0052] Na 2 O 1.1%

[0053] al 2 o 3 14.83%

[0054] Fe 2 o 3 2.1%

[0055] CaO 7.5%

[0056] MgO 0.37%

[0057] TiO 2 0.28%

[0058] Mix 25% of the Longquan celadon antibacterial agent prepared above with 75% of traditional celadon underglaze to make antibacterial glaze dry agent. Dissolve the antibacterial glaze dry agent with water and ball-mill it into a glaze slurry. First, dip the celadon carcass in a layer of celadon bottom glaze, and then use a spray gun to evenly spray the antibacterial glaze on the surface of ordinary celadon glaze. After drying, it is fire...

Embodiment 3

[0061] In weight percentage, mix 50% of Longquan celadon glaze, 30% of nano-silicon oxide and 20% of silver phosphate, mix evenly, grind finely, and pass through a 300-mesh sieve to obtain Longquan celadon antibacterial agent.

[0062] The chemical composition of Longquan celadon glaze in this embodiment is:

[0063] SiO 2 69.17%

[0064] K 2 O 4.8%

[0065] Na 2 O 1.2%

[0066] al 2 o 3 14.8%

[0067] Fe 2 o 3 1.9%

[0068] CaO 7.3%

[0069] MgO 0.57%

[0070] TiO 2 0.26%

[0071] Mix 35% of the Longquan celadon antibacterial agent prepared above with 65% of the traditional celadon underglaze to make antibacterial glaze dry agent. Dissolve the antibacterial glaze drying agent with water and ball mill it into glaze slurry, immerse the celadon carcass in the antibacterial glaze, dry it and then fire it at 1250-1350 degrees Celsius.

[0072] The antibacterial glaze obtained in this embodiment has a bactericidal rate of 96% fo...

Abstract

The invention discloses a dragon spring celadon antibacterial agent, which comprises the following components according to weight percentage: 45 percent to 65 percent of dragon spring celadon glaze, 15 percent to 35 percent of nano silicon oxide and 15 percent to 30 percent of silver phosphate. The invention also discloses an application of the dragon spring celadon antibacterial agent in preparing the celadon antibacterial glaze, the dragon spring celadon antibacterial agent and celadon underglaze are mixed to prepare the antibacterial glaze dry agent. The antibacterial glaze dry agent is dissolved by adding water, is ball-milled into glaze slurry, is glazed by adopting a mode of dipping glaze or spraying glaze and then is fired into celadon antibacterial glaze; under the premise of keeping the style of the traditional celadon not to be changed, the glazed surface thereof is added with the antibacterial function, the sterilizing rate for escherichia coli and staphylococcus aureus reaches to more than 90 percent.

Description

technical field [0001] The invention relates to a special antibacterial agent for Longquan celadon, and the application of the antibacterial agent in the preparation process of celadon antibacterial glaze, which is suitable for the production of Longquan celadon daily-use porcelain, porcelain for displaying ritual wares, architectural decorative porcelain, packaging porcelain (wine bottles), etc. field. Background technique [0002] In the history of Chinese porcelain making, Longquan celadon is the kiln system with the longest firing time, the widest distribution and the greatest influence. It rose in the late Tang and Five Dynasties, reached its peak from the Southern Song Dynasty to the Yuan Dynasty, and began to decline after the late Ming Dynasty. The production history is long. For thousands of years. Longquan kiln produces a wide variety of high-quality celadon products. It is famous for its bright green color of thousands of peaks and crystal clearness of "ice like ...
