Embodiment 1

[0024] The raw material formula is as follows: coal gangue 60%, construction waste 15%, shale 15%, tailing slag 10%.

[0025] According to the above ratio, grind it to 80 mesh, add 17% water and stir it; stale for 36 hours, use an extrusion molding machine to extrude it into a thin plate with a middle hole; dry it; put it into a kiln and burn it at 1150°C That's it.

Embodiment 2

[0027] The raw material formula is as follows: coal gangue 70%, construction waste 20%, shale 5%, tailings slag 5%.

[0028] According to the above proportions, grind it to 40 mesh, add 18% water and stir; stale for 48 hours, use an extrusion molding machine to extrude it into a thin plate with a middle hole; dry it; put it into a kiln and burn it at 1180°C That's it.

Abstract

The invention relates to a hollow ceramic insulation board for coal gangues and construction wastes and a manufacturing method thereof. In the invention, a large amount of coal gangues and construction wastes are taken as raw materials, and 50-70% of coal gangues, 10-30% of construction wastes, 5-15% of shale and 5-10% tailing residues are mixed in accordance with a formula. The manufacturing method thereof comprises the following steps: mixing the materials in the formula, grinding the materials to 40-80 meshes, adding 15-20% of water to stirring, aging the mixture for 24-72h, extruding laminas with mesopores by an extruder, drying the laminas, and performing calcination on the dried laminas in a kiln at the temperature of 1100-1200 DEG C to obtain the hollow ceramic insulation board for coal gangues and construction wastes. The invention is characterized in that a large amount of the coal gangues and the construction wastes are taken as the raw materials for the products, and usage amount of the coal gangues and the construction wastes reaches above 70%; the products are ceramic laminas with the mesopores; the water absorption of the products is lower than 3.5%, the strength is high and the weather fastness is strong; and the coefficient of heat conductivity of the products is lower than 0.45w/(m.K) and the thermal insulation property is good.

Description

1. Technical field [0001] The invention discloses a ceramic hollow outer wall board for outer wall decoration and heat preservation by using coal gangue and construction waste as main raw materials and a manufacturing method thereof. 2. Background technology [0002] Driven by the wave of building a green and energy-saving society, people's expectations and pursuits for building energy conservation are increasing day by day, and various wall enclosure systems such as block external insulation systems, block sandwich (fill) core systems and panel composite insulation systems have been adopted. . However, many technologies are still immature and have various shortcomings. It is imperative to develop new energy-saving and thermal insulation building decoration materials. [0003] Insulation bricks are developed to meet this demand. Insulation bricks have multiple effects such as decoration, sound insulation, heat preservation and energy saving. It is a new generation of ext...
