Embodiment 1

[0042] The preparation of embodiment 1 additive ZL

[0043] The additive ZL is obtained by grinding the following components into a ball mill, sieving, dehydrating, pre-firing, and superfine grinding with zirconium corundum grinding media (on the order of 1000g).

[0044] In terms of parts by mass, there are 70 parts of zirconia; 6 parts of feldspar; 3 parts of rare earth; and 5 parts of clay.

[0045] The fine pulverization is pulverization to a particle size range of 250-350 mesh.

[0046] The main technical conditions of the pre-firing are: firing with an oxidizing flame, and the key condition is to keep warm at about 1250° C. for 2 hours. Others refer to existing routines.

Embodiment 2

[0047] The preparation of embodiment 2 additive ZL

[0048] The additive ZL is obtained by using the following components to be finely pulverized by a ball mill, sieved, dehydrated, pre-fired, and superfinely pulverized by a zirconium corundum grinding medium.

[0049] In terms of parts by mass, there are 85 parts of zirconium silicate; 10 parts of feldspar; 5 parts of rare earth; and 2 parts of clay.

[0050] The fine pulverization is pulverization to a particle size range of 250-350 mesh.

[0051] The main technical conditions of the pre-firing are: firing with an oxidizing flame, and the key condition is to keep warm at about 1350° C. for 1.5 hours.

Embodiment 3

[0052] The preparation of embodiment 3 additive ZL

[0053] The additive ZL is obtained by using the following components to be finely pulverized by a ball mill, sieved, dehydrated, pre-fired, and superfinely pulverized by a zirconium corundum grinding medium.

[0054] In terms of parts by mass, there are 75 parts of zirconia; 8 parts of feldspar; 2 parts of rare earth; and 10 parts of clay.

[0055] The fine pulverization is pulverization to a particle size range of 250-350 mesh.

[0056]The main technical conditions of the pre-firing are: firing with an oxidizing flame, and the key condition is to keep the temperature at 1280° C. for 1 hour.

[0057] Art conditions are with reference to prior art routine.

Abstract

A reinforced bone china for daily use and a preparing method thereof are disclosed. The bone china for daily use is prepared from, by mass, 1-3 parts of an additive ZL, 40-45 parts of bone char, 10-12 parts of quartz, 10-12 parts of feldspar, 24-28 parts of kaolin, 48-52 parts of water, 1-3 parts of a crystal form improving agent, 1-2 parts of a mineralizer and 1-3 parts of a phosphosilicate targeting fluxing agent. Through scientifically introducing the phosphosilicate targeting fluxing agent, introduction of potassium-containing and sodium-containing mineral raw materials is significantly reduced, and the sintering temperature and the expansion coefficient of a blank are controlled well. Through introducing the additive ZL, the crystal form improving agent and the mineralizer into bone china pug, uniform crystal growth in a stage of vitrification to form the china is ensured, a phosphosilicate glass phase network is further complete, and mechanical strength and thermal shock resistance of the bone china are finally improved. The bone china for daily use is high in mechanical strength, smooth in glaze, easy to clean, significantly reduced in lead and cadmium dissolving-out amounts, and good in thermal shock resistance.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a daily-use porcelain for strengthening bone and a preparation method thereof. Background technique [0002] Bone china porcelain is fine and smooth, with smooth glaze and soft luster. It looks like fat and jade. , the quality requirements for daily-use ceramics are getting higher and higher, and the application of bone china is becoming more and more extensive. It is recognized as the highest-grade porcelain in the world today, and is deeply loved by consumers. market expectation. [0003] However, the quality of existing bone china products is difficult to control. The main problems are low strength, poor thermal shock resistance, high lead and cadmium dissolution, and insufficient glaze. With the improvement of people's living standards, consumers have higher and higher requirements for daily-use porcelain, not only for its appearance, such as shape, decoration, etc., but a...
