Abstract

The invention relates to a light high-strength ceramic tile. A manufacturing method for the light high-strength ceramic tile comprises the following steps: (1) weighing the following raw materials in parts by weight: 4-9 parts of corundum, 10-16 parts of spinel, 3-6 parts of sugilite, 11-17 parts of mullite, 12-19 parts of quartz, 2-4 parts of refractory fibers, 8-13 parts of mica and 5-10 parts of shale, uniformly mixing the raw materials, crushing the raw materials, performing wet-process ball milling on the crushed raw materials for 5-7 hours, drying and enabling the raw materials to pass through a 300-meshsed sieve to obtain powder for later use; (2) feeding powder obtained in the step (1) into a molding machine for pressing and molding under 70MPa to obtain a tile green body; and (3) introducing the pressed tile green body into a kiln for burning, heating up to 1180 DEG C at a rate of 20 DEG C / min, preserving heat for 1 hour, cooling to 900 DEG C at the rate of 15 DEG C / min, preserving the heat for 30 minutes, heating to 1050 DEC at the rate of 10 DEG C / min, preserving the heat for 2 hours, and naturally cooling, thereby obtaining the light high-strength ceramic tile. The prepared light high-strength ceramic tile has density of 1.2-1.4g / cm<3> and rupture strength greater than 25MPa.

Description

technical field [0001] The invention relates to the field of architectural ceramic materials, more specifically, to a light-weight high-strength ceramic tile. Background technique [0002] Lightweight bricks can reduce the cost of the foundation, reduce the cross-section of the frame, and save reinforced concrete can significantly save the overall cost of the building. The use of lightweight bricks can increase the usable area. At the same time, due to the heat insulation of aerated concrete, the thermal insulation effect is good, and it has good machinability. The construction is convenient and simple. Due to the large block and light weight, it can reduce labor intensity and improve construction efficiency. Shorten the construction period. However, the lightweight bricks on the market are usually not high in strength, fragile, and have a short service life. Contents of the invention [0003] The object of the present invention is to provide a light-weight high-strength...
