Embodiment 1

[0025] The formula ratio is as follows: 80% raw material for ceramic tiles, 10% perlite, 0.03% water glass, 5% bentonite, 5% stone powder, and 0.15% silicon carbide. Among them, the raw material composition of ceramic tiles is: 72.0% SiO 2 , 14.0%Al 2 o 3 , 1.3% CaO, 1.6% MgO, 3.7% K 2 O and 2.7% Na 2 O, loss on ignition 3.7%. Raw materials are prepared according to the proportion, put into a ball mill to grind fully, and then spray-dried. It is pressed and formed on the ordinary exterior wall brick production line, and then fired in a roller kiln after drying. The total firing time is 35 minutes, and the firing temperature is 1200°C. It takes about 12 minutes to rise to 1000°C, and about 8 minutes for 1000°C to 1200°C. The apparent density of the obtained product is 0.98g / cm 3 , the average bubble diameter is about 0.5mm, and the thermal conductivity is 0.153W / m·K.

Embodiment 2

[0027] The formula ratio is as follows: 70% raw material for ceramic tiles, 20% perlite, 5% bentonite, 3% gypsum, 2% sawdust, and 0.2% silicon carbide. The raw material composition of ceramic tiles is: 69.3% SiO 2 , 16.2% Al 2 o 3 , 1.7% CaO, 1.1% MgO, 2.6% K 2 O and 1.4% Na 2 O, loss on ignition 7.7%. Prepare the raw materials according to the proportion, put them into the planetary ball mill to grind them thoroughly, and press them into shape after drying. The total firing time is 60 minutes, the firing temperature is 1180°C, and it takes about 20 minutes to rise to 1000°C, about 15 minutes to reach 1000°C to 1180°C, and about 5 minutes to keep warm. The apparent density of the obtained product is 0.92g / cm 3 , The average bubble diameter is about 1mm.

Embodiment 3

[0029] The formula ratio is as follows: 60% of ceramic brick raw material, 20% of perlite, 10% of diatomite, 5% of bentonite, 3% of fluorite, 2% of barium sulfate, and 0.1% of silicon carbide. The raw material composition of ceramic tiles is: 76.0% SiO2, 12.0% Al2O3, 1.2% CaO, 2.3% MgO, 2.5% K2O and 2.0% Na2O, and the loss on ignition is 4.0%. Prepare the raw materials according to the proportion, put them into the planetary ball mill to grind them thoroughly, and press them into shape after drying. The total firing time is 90 minutes, the firing temperature is 1180°C, and it takes about 60 minutes to rise to 1000°C, about 20 minutes to reach 1000°C to 1180°C, and about 10 minutes to keep warm. The apparent density of the obtained product is 0.88g / cm 3 , the average bubble diameter is about 1mm, and the thermal conductivity is 0.14W / m·K.

Abstract

The invention discloses light thermal-insulation ceramic tiles, which are prepared by using the following raw materials in percentage by weight: 60.0 to 90.0 percent of ceramic tile raw material, 2.0 to 10.0 percent of additive, 10 to 20 percent of pore-forming material and 0.01 to 2 percent of foaming agent. The ceramic tiles are light, nonabsorbent, heat-proof, fire retardant, nontoxic, harmless, chemical corrosion resistance and mouldproof. The ceramic tiles have a small conductivity factor, stable performance and high mechanical strength. The ceramic tiles are low in cost, simple in process, convenient and quick in construction and good in decoration effect.

Description

technical field [0001] The invention relates to a light-weight thermal insulation ceramic tile and a preparation method thereof, and aims to prepare a lightweight thermal insulation ceramic tile integrating thermal insulation, heat insulation, waterproof, moisture-proof and decoration. Background technique [0002] At present, my country's building energy consumption has accounted for 30% of the total energy consumption, and building energy conservation has become the focus of energy conservation and emission reduction. It is of great significance to develop new thermal insulation and energy-saving wall materials and improve the thermal insulation performance of external walls to achieve building energy conservation. A large number of engineering practices have proved that wall insulation technology is the best way to achieve building energy conservation and insulation. [0003] The density of existing ceramic tiles is 2.5g / cm 3 Left and right, dense facing bricks add weig...
