Problems solved by technology

However, this concrete block has many disadvantages, such as heavy weight and unattractive appearance.
[0003] There are some existing insulation bricks, although the weight is lighter than concrete blocks, but due to the use of organic matter such as wood chips, smoke will be generated during sintering, which is not conducive to environmental protection, and most of them are rough billets with an unattractive appearance

Embodiment 2

[0056] Except that the formula is different from Example 1, the process of this example is basically the same as Example 1.

[0057] Weigh the corresponding raw materials according to the ratio of the green body formula in Table 3, and add them to the ball mill for grinding. The grinding time is 26 hours. At high temperature, the slurry turns into powder. Afterwards, the green body is made to the same as that of Example 1 until the dotting process. The sintering temperature of this embodiment is 1200°C high-temperature rapid sintering for 75 minutes.

[0066] Weigh the corresponding raw materials according to the proportion of the body formula in Table 5, add them to the ball mill for grinding, and the grinding time is 20 hours. After the ball milling, unload the mud, pass the mud through a 200-mesh filter, and then inject the mud into the spray tower through the pipeline. At high temperature, the slurry turns into powder. Afterwards, the green body is made to the same as that of Example 1 until the dotting process. The sintering temperature of this embodiment is 1300°C high-temperature rapid sintering for 60 minutes.

Abstract

The invention discloses a light heat-preserving brick and a fabrication method thereof. The light heat-preserving brick comprises a green body layer and can also comprises a glaze layer which can totally or partly cover the green body layer, wherein the green body layer includes the following compositions, by weight: 60.0-70.0 pyrophyllite, 3.0-8.0 clay, 20.0-25.0 white talc, 3.5-5.0 feldspar, 0.5-1.4 glass and 0.3-0.8 carbonate. The method includes the steps of fabricating the green body layer, fabricating the ground glaze and fabricating the spot glaze. The light heat-preserving brick has the advantages of light weight, heat preservation property, big strength and attractive appearance.

Description

technical field [0001] The invention relates to a building material, in particular to a lightweight insulating brick for roofs and a manufacturing method thereof. Background technique [0002] With the development of society, the requirements for building energy saving are getting higher and higher. Correspondingly, the requirements for the thermal insulation and heat insulation functions of building materials are also getting higher and higher. For the wall, hollow bricks and other methods can be used for heat insulation. For the roof, in the past, large concrete cubes are usually placed on the bricks, and the gap between the concrete block and the roof is used for heat insulation. However, this concrete block has many disadvantages, such as heavy weight and unattractive appearance. [0003] Some existing insulation bricks are lighter than concrete blocks, but due to the use of organic matter such as wood chips, smoke will be generated during sintering, which is not conduc...
