Problems solved by technology

The applicant applied for a patent application number of 00100030.6 on January 5, 2000, and the Chinese patent application titled "A Production Method for a Novel Glass-ceramic-Ceramic Composite Brick" discloses a method for preparing glass-ceramic- The method of ceramic composite bricks, the glass-ceramic ceramic composite bricks made by this method are beautiful in appearance, but the pattern of the glass-ceramics layer on the surface is spherical, and the crystal growth fails to break through the particle boundaries
In addition, the color patterns of the known pure glass-ceramic plates are also mainly spherical, and none of them can break through the particle boundaries.

Embodiment 1

[0025] By chemical composition: SiO 2 48.42%, Al 2 o 3 5.16%, Na 2 O+K 2 O 4.01%, CaO 14.9%, ZnO 23.53%, BaO 3.98%, plus clarifying agent 0.6% of the total amount of the above materials, select the corresponding quartz, feldspar, calcium carbonate, barium carbonate, zinc oxide below 0.1mm , clarifying agent and other raw materials, weighed according to the formula, mixed evenly, and melted in a glass furnace with a melting temperature of 1480°C. The melt is water-quenched after being clarified, and extruded by a pair of rollers during water-quenching to obtain surface-layer glass-ceramic pellets of ≤6mm.

[0026] By chemical composition: SiO 2 68.27%, Al 2 o 3 17.66%, Fe 2 o 3 0.67%, TiO 2 0.11%, CaO 1.01%, MgO 1.21%, K 2 O 1.62%, Na 2O 4.79%, loss on ignition 4.66%, select various raw materials such as corresponding kaolin, china stone (soil), clay, bentonite, quartz, feldspar (potassium, albite), talc, etc., and crush to below 5mm. Weigh according to the fo...

Embodiment 2

[0029] Carry out according to each step of embodiment 1, but increase the manganese dioxide of 1.6% in addition in the composition of surface layer glass-ceramic, obtain the high-grade glass-ceramic-ceramic composite brick that spreads out spherical crystal like this.

Embodiment 3

[0031] Carry out according to each step of embodiment 1, but increase the nickel oxide of 0.3% in addition in the composition of surface layer glass-ceramic, obtain the high-grade glass-ceramic-ceramic composite brick that is all over spherical crystal of brown like this.

Abstract

The present invention relates to a nucleated glass composite material and its preparation method. Said composite material is formed from surface layer nucleated glass and base material. Its surface layer bucleated glass includes ZnO 10-40% (wt%), SiO2, Al2O3, CaO, MgO, Na2O+K2O, Li2O, BaO and ZrO2, and its base material is ceramic or nucleated glass layer. Said nucleated glass is made up by following steps: preparing surface layer nucleated glass granulated raw material, preparing base material, combining them and making them into semi-finished product, edge grinding, scrapping, coarse grinding, polishing, edge grindnig, chamferring and drying, and the pattern of the obtained nucleated glass copmosite material can be various forms of ball, chrysanthemum flower, slag flow, flower cluster, flowing lines, flame and radiation, etc.

Description

technical field [0001] The invention relates to a novel glass-ceramic composite material and a preparation method thereof. Background technique [0002] Glass-ceramic has become a high-grade decorative material due to its smoothness, bright colors and beautiful patterns. The applicant applied for a patent application number of 00100030.6 on January 5, 2000, and the Chinese patent application titled "A Production Method for a Novel Glass-ceramic-Ceramic Composite Brick" discloses a method for preparing glass-ceramic- The ceramic composite brick method, the microceramic glass-ceramic composite brick made by this method has a beautiful appearance, but the pattern of the microcrystalline glass layer on its surface is spherical, and the crystal growth fails to break through the particle boundary. In addition, the color patterns of the known pure glass-ceramic plates are also mainly spherical, and none of them break through the particle boundaries. Contents of the invention ...
