Embodiment 1

[0020] Prepare the ceramic glaze according to the following proportions: 39% potassium feldspar, 11% marble, 38% silica, 4% antibacterial agent, and 8% titanium dioxide. All are percentages by weight.

[0021] (1) Potassium feldspar, marble, silica, antibacterial agent and titanium dioxide are mixed through a ball mill, and ground in a ball mill for 20 hours;

[0022] (2) After mixing evenly, filter through a vibrating sieve three times to remove iron;

[0023] (3) After iron removal, after 2 days of decontamination, the remaining small amount of impurities sinks in the lower layer, and after filtration, the finished ceramic glaze is obtained. After determination, its composition and ratio are: SiO 2 52%, Al 2 o 3 9%, CaO 10%, K 2 O 6%, Na 2 O 1%, ZnO 3%, Li 2 O 3%, TiO 2 8%, V 2 o 5 3%, Ag 2 o 3 5%;

[0024] (4) Spray the finished ceramic glaze on the ceramic body and fire at a high temperature of 1200°C to obtain the finished product.

Embodiment 2

[0028] Prepare the ceramic glaze according to the following proportions: 40% potassium feldspar, 13% marble, 38% silica, 4% antibacterial agent, and 5% titanium dioxide. All are percentages by weight.

[0029] (1) Potassium feldspar, marble, silica, antibacterial agent and titanium dioxide are mixed through a ball mill, and ground in a ball mill for 26 hours;

[0030] (2) After mixing evenly, filter through a vibrating sieve 4 times to remove iron;

[0031] (3) After iron removal, after 3 days of decontamination, the remaining small amount of impurities sinks in the lower layer, and after filtration, the finished ceramic glaze is obtained. After determination, its composition and ratio are: SiO 2 68%, Al 2 o 3 8%, CaO 9%, K 2 O 5%, Na 2 O 0.5%, ZnO 0.5%, Li 2 O 1%, TiO 2 6%, V 2 o 5 1%, Ag 2 o 3 1%;

[0032] (4) Spray the finished ceramic glaze on the ceramic body and fire at a high temperature of 1270°C to obtain the finished product.

Embodiment 3

[0034] Prepare the ceramic glaze according to the following proportions: 43% potassium feldspar, 12% marble, 38% silica, 2% antibacterial agent, and 5% titanium dioxide. All are percentages by weight.

[0035] (1) Potassium feldspar, marble, silica, antibacterial agent and titanium dioxide are mixed through a ball mill, and ground in a ball mill for 24 hours;

[0036] (2) After mixing evenly, filter through a vibrating sieve 5 times to remove iron;

[0037] (3) After iron removal, after 4 days of decontamination, the remaining small amount of impurities sinks in the lower layer, and after filtration, the finished ceramic glaze is obtained. After determination, its composition and ratio are: SiO 2 72%, Al 2 o 3 5%, CaO 6%, K 2 O 2%, Na 2 O 1.5%, ZnO 2.5%, Li 2 O 2%, TiO 2 4%, V 2 o 5 2%, Ag 2 o 3 3%;

Abstract

The invention discloses a self-cleaning antibacterial ceramic glaze and a preparation method and a ceramic product thereof. The key of the self-cleaning antibacterial ceramic glaze provided by the invention is that the ceramic glaze contains Ti element and Ag element. The ceramic glaze comprises the following components in percentage: 52-72% of SiO2, 5-9% of Al2O3, 6-10% of CaO, 2-6% of K2O, 0.5-1.5% of Na2O, 0.5-3% of ZnO, 1-3% of Li2O, 4-8% of Ti2O, 1-3% of V2O5 and 1-5% of Ag2O3. The ceramic product of the invention comprises a ceramic noumenon, which is characterized by containing a self-cleaning antibacterial ceramic glaze layer on the surface of the ceramic noumenon. The composition of the invention is suitable to be adopted in primary glazing process, and the surface of the ceramic glaze has high flatness, fined and delicate crystalloid, good smooth finish, no needle pole, extremely soft and good glass like and smooth in touch and reaches the self-cleaning antibacterial effect of ultra smooth glaze layer enamel.

Description

technical field [0001] The invention relates to a ceramic glaze and its application technology. Background technique [0002] Traditional ceramics are mainly white, and the glaze only uses zirconium silicate to play a white role, and has no other functions, and the traditional ceramic glaze is uneven under a magnifying glass, making it easy for dirt and bacteria to hide and multiply; later, in traditional ceramics After the finished product is fired, heat treatment of the coating film is added in the later stage. Without high-temperature firing, the coating film has poor stability and is easy to peel off, and finally loses the antifouling and antibacterial effect. [0003] Chinese invention patent ZL02125311.0 discloses a sanitary ware with a nanometer self-cleaning glaze, which is characterized in that the surface glaze contains Ag 2 o 3 and ZnO nanocomposite antibacterial agent, and the required sanitary ware is made by glazing twice and firing once. The sanitary ware o...
