Embodiment 1

[0029] An easy-to-clean daily-use ceramics, the composition of which is calculated according to the following weight percentages: 58% silicon dioxide, 3% aluminum oxide, 4% calcium oxide, 26% magnesium oxide, 0.85% potassium oxide, 0.15% sodium oxide, Zinc oxide 3.5%, negative ion powder 2%.

[0030] The preparation method of the above-mentioned easy-to-clean daily-use ceramics comprises the following steps:

[0031] S1. Add the raw materials in the above ratio into a ball mill, and perform wet ball milling according to the weight ratio of ball stone: water: material = 1.8:1:1 to obtain a slurry;

[0032] S2. Add zirconium beads to the slurry obtained in S1, and stir and ball mill according to the weight ratio of slurry: zirconium beads=1:1.5;

[0033] S3. removing iron from the above slurry in a 18000 gauss iron remover;

[0034] S4. Sieve the slurry after iron removal, the fineness of the sieve is 325 mesh, and the remaining 0.8% of the sieve is obtained to obtain the filt...

Embodiment 2

[0040] An easy-to-clean daily-use ceramic, the composition of which is calculated according to the following weight percentages: 60% silicon dioxide, 2% aluminum oxide, 3% calcium oxide, 26% magnesium oxide, 0.8% potassium oxide, 0.14% sodium oxide, Zinc oxide 4%, negative ion powder 3%.

[0041] The preparation method of the above-mentioned easy-to-clean daily-use ceramics is the same as that in Example 1, except that the aging time in step S5 is 11 days, and the water content of the green body in step S7 is 6%.

Abstract

The invention belongs to the technical field of ceramics, and particularly relates to easy-to-clean domestic ceramic and a preparation method of the easy-to-clean domestic ceramic. The easy-to-clean domestic ceramic comprises the following ingredients in percentage by weight: 58-62% of silicon dioxide, 2-3% of aluminum oxide, 2-4% of calcium oxide, 22-26% of magnesium oxide, 0.7-0.9% of potassium oxide, 0.11-0.15% of sodium oxide, 3-5% of zinc oxide and 2-3% of anion powder. The preparation method comprises the steps of mixing the raw materials for wet ball milling to form slurry, removing iron from the slurry, sieving and staling the slurry, then performing fine treating, grouting and roll forming, and performing drying and firing at last. The easy-to-clean domestic ceramic contains multiple rare earth metal oxides that generate a synergistic effect to raise an easy-to-clean degree of the easy-to-clean domestic ceramic, and the easy-to-clean domestic ceramic has significant self-cleaning ability and an effective effect of sterilization and bacterial inhibition.

Description

technical field [0001] The invention belongs to the technical field of ceramics, and in particular relates to an easy-to-clean daily-use ceramic and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, the requirements for the quality and convenience of daily-use ceramic products are also getting higher and higher, and the easy-cleaning performance of ceramics has also become the latest requirement of consumers. Since the current ceramic raw material formula and production process are relatively outdated, the surface of fired ceramic products for daily use is not easy to clean. A lot of research, the patent discloses a daily-use ceramic with high easy-to-clean performance, which improves the cleanliness of the ceramic surface through the combination of various compounds that improve the cleanliness. After testing, the residual oil on the surface is as low as 0.4g / m². Contents of the invention [0003] The purpo...
