preparation example Construction

[0035] Correspondingly, the embodiment of the present invention also provides a method for preparing an energy-saving luminescent ceramic. The method comprises the steps of:

[0036] S01. Weigh each component according to the energy-saving luminous ceramics;

[0037] S02. Mix the basic ceramic powder and the light-storing luminescent powder to form a first mixture;

[0038] S03. Adding forming aids to the first mixture, sieving, pressing and forming, drying, and one-time firing into energy-saving luminescent ceramics.

[0039] Specifically, the energy-saving luminescent ceramics in the above step S01 and the preferred content and types of its components are as described above, and will not be repeated here to save space.

[0040] Specifically, in the above step S02, the basic ceramic powder and the light-storing luminescent powder are mixed uniformly to form a first mixture. The mixing method can be conventional mixing methods such as solid-phase mixing and other methods, t...

Embodiment 1

[0048] An energy-saving luminescent ceramic, the raw materials of which include basic ceramic powder and light-storing luminescent powder. Among them, the content of the basic ceramic powder is SiO 2 68.61%; Al 2 o 3 6.89%; B 2 o 3 8.3%; Li 2 O 0.01%; K 2 O1.42%; CaO4.7%; Na 2 O 5.86%; ZnO 1.89%; BaO 2.32%; after mixing the above components evenly, melt them at 950°C, and grind them with a ball mill to prepare the basic ceramic powder; the luminescent powder is made of rare earth doped strontium aluminate Rare earth phosphor is SrAl 2 o 4 :(Eu 2+ 、Dy 3+) .

[0049] Raw material formula and preparation method of energy-saving luminescent ceramics: take 70 parts of the basic ceramic powder prepared above and 30 parts of light-storing luminescent powder, mix them evenly, then add 1 part of molding aid, and mix them to make a 25-mesh sieve. The powder is formed by semi-dry pressing, dried in an oven at 50°C for 1 hour, and fired at 950°C in a neutral atmosphere to f...

Embodiment 2

[0051] An energy-saving luminescent ceramic, the raw materials of which include basic ceramic powder and light-storing luminescent powder. Wherein, the content of the basic ceramic powder, the preparation method and the added substances of the light-storing luminescent powder are the same as those described in Example 1, and will not be discussed here.

[0052] Raw material formula and preparation method of energy-saving luminous ceramics: take 30 parts of the basic ceramic powder prepared above and 70 parts of light-storing luminescent powder, mix them evenly, then add 5 parts of molding aids, and mix them to make a 25-mesh sieve. The powder is formed by semi-dry pressing, dried in an oven at 50°C for 1 hour, and fired at 1050°C in a neutral atmosphere to form a luminescent ceramic product.

Abstract

The invention provides an energy-saving luminescent ceramic. Raw materials of the energy-saving luminescent ceramic comprise, by weight, 50-95 parts of basic ceramic powder and 5-50 parts of light-storing luminescent powder, and the basic ceramic powder is mixed with the light-storing luminescent powder. The light-storing luminescent powder is a substance that absorbs energy and continuously emitslight after the excitation is stopped, so it is ensured that the prepared energy-saving luminescent ceramic has the advantages of good light-storing performance, high hardness, high strength, good wear resistance, long afterglow time, stable luminescence performance, simple and easy preparation process, and facilitation of wide use.

Description

technical field [0001] The invention relates to the field of inorganic non-metal, in particular to an energy-saving luminescent ceramic and a preparation method thereof. Background technique [0002] The development history of ceramics is an important part of the history of Chinese civilization. As one of the four ancient civilizations, China has made outstanding contributions to the progress and development of human society. Among them, the invention and development of ceramics has unique significance. Different dynasties and dynasties in Chinese history have different artistic styles and different technical characteristics. "china" in English means both China and ceramics, which clearly shows that China is the "hometown of ceramics". As early as more than a thousand years before the Europeans mastered the porcelain manufacturing technology, the Han people had already produced very exquisite ceramics. China is one of the first countries in the world to use pottery, and Ch...
