Embodiment 1

[0021] In terms of mass percentage, 15% Sr4A14O25 doped Eu2+, Dy3+ energy storage luminescent material and 15% CaAl2O4 doped Eu2+, Nd3+ energy storage luminescent material are passed through 800 mesh sieve together, and 70% low temperature frit (fineness is 70-100 mesh) and then pass through 80 mesh sieve. Take the ceramic biscuit, pass the mixed frit through an 80-mesh mesh, and spread it on the ceramic biscuit, and then apply a layer of low-temperature frit. Afterwards, it is fired in a kiln at 850°C, edged and polished, and the finished product is a light-storing ceramic tile that emits sky blue light in the dark, and the afterglow time is as long as 6.5 hours. The ceramic brick has grade 4 wear resistance, good weather resistance, not easy to aging, strong chemical corrosion resistance, 18% (V / V) hydrochloric acid - GHA grade, 100g / L potassium hydroxide - GHA grade.

Embodiment 2

[0023] According to mass percentage, pass 25% of Sr2MgSi2O7 energy storage luminescent material through 800 mesh sieve, mix with 25% glaze frit (fineness is 100-200 mesh) and pass through 80 mesh sieve, then add 50% printing oil, Stir well. The mixed slurry is passed through an 80-mesh screen and printed on the ceramic biscuit blank, and then a layer of low-temperature frit is applied. Afterwards, it is fired in a kiln at 950°C, edged and polished, and the finished product is a light-storing ceramic tile that emits blue-green light in the dark, with an afterglow time of up to 8 hours. The ceramic brick has grade 4 wear resistance, good weather resistance, not easy to aging, strong chemical corrosion resistance, 18% (V / V) hydrochloric acid - GHA grade, 100g / L potassium hydroxide - GHA grade.

Abstract

The invention discloses a thermal-insulation luminescent ceramic brick and a preparation method thereof. A photoluminescent material is made into a photoluminescent glassy layer on a ceramic biscuit through a printing or distribution process, and the photoluminescent glassy layer shows various colors in the dark and the afterglow time is long. A silk-screen printing or distribution process can beadopted, patterns can be replaced momentarily, and with the cooperation of pigment toning and concave and convex molds, various decorative artistic effects with strong three-dimensional sense and richpattern layers can be presented. By the method of the invention, problems of existing photoluminescent materials such as poor wear resistance, weatherability and chemical corrosion resistance are solved.

Description

technical field [0001] The invention belongs to the field of preparation of architectural ceramic products, and in particular relates to a thermal insulation luminescent ceramic brick and a preparation method thereof. Background technique [0002] Photoluminescent materials are also called light-storage self-luminous materials, non-radioactive light-storage materials, self-luminous materials without power supply, etc. After the material actively absorbs visible light such as sunlight, light, ultraviolet light, and stray light for 5-10 minutes, it can continue to emit light in the dark for 6-8 hours, and can emit red, green, blue, Yellow, purple and other colored lights. Due to its excellent physical and chemical properties such as high brightness, fast light absorption, and long storage light, it is widely used in architectural decoration, transportation, fire safety, electronic communications, electrical appliances, instruments, petrochemicals, subway tunnels, printing and...
