[0003] (1) The durability is not good. The design service life of the building structure is generally 50 years, while the service life of the polystyrene board is only 10 to 15 years, which cannot meet the requirements of the building's service life;
[0004] (2) Flammable. Since polystyrene board is an organic material, it will be burned rapidly in case of fire, resulting in structural damage. Therefore, it is urgent to develop non-combustible and lightweight insulation materials

Embodiment 1
[0061] (1) Mix construction waste to waste bricks and tiles in proportions of 60%, clay 35%, and coal powder 5% and preliminarily crush them. Then put the batches into a ball mill and grind them to about 240-260 mesh. After ball milling The batch materials are granulated, and the particle size is about 8-15mm.
[0062] (2) Put the granulated batch material into a box-shaped mold, and lay a layer of 1.5mm glass fiber paper between the mold and the batch material to prevent the light ceramic tile from sticking to the mold.
[0063] (3) Move the loaded mold into the kiln for heating, start heating from room temperature to 980°C, and the heating rate is 12°C / min; it takes 60min from 980°C to 1130°C; keep it at 1130°C for 40min, from Cool rapidly at 15°C / min from 1130°C to 580°C, keep warm at 580°C for 30 minutes, then cool down to 80°C at a rate of 1°C / min, and start the kiln to obtain lightweight ceramic tiles. Lightweight ceramic tiles have a uniform structure and a density of ...

[0079] (1) Prepare construction waste-waste bricks and tiles according to the proportion of 75%, clay 22%, coal powder 1%, calcium carbonate 3% and preliminarily crush them, and then put the batch materials into a ball mill and grind them to 240-260 mesh Left and right, the batch after ball milling is granulated, and the particle size is about 8-15mm.
[0080] (2) Put the granulated batch material into a box-shaped mold, and lay a layer of 1.5mm thick glass fiber paper between the mold and the batch material. Move the loaded mold into the kiln for heating, from room temperature to 980°C, the heating rate is 18°C / min; from 980°C to 1130°C, it takes 40 minutes; at 1130°C for 30 minutes, from 1130°C to 580°C Cool at a rate of 20°C / min, keep warm at around 580°C for 30 minutes, then cool down to 80°C at a rate of 1.5°C / min, and start the kiln to obtain lightweight ceramic tiles.

Abstract
The invention discloses a decorative heat insulation foam ceramic composite plate. The composite plate is composed of a decorative mortar surface layer and a foam ceramic insulation layer. The decorative mortar surface layer comprises the following raw materials: 1900 kg / m<3> to 2300 kg / m<3> of a fine aggregate, 420kg / m<3> to 510kg / m<3> of cement, 15kg / m<3>-30kg / m<3> of silica fume, 50kg / m<3>-90kg / m<3> of an admixture, 2.9kg / m<3>-4.2kg / m<3> of a water reducer, 95kg / m<3>-130kg / m<3> of water and 0-8kg / m<3> of an inorganic pigment. The foam ceramic insulation layer is composed of the following raw materials by weight percentage: 50-85% of construction waste, 10-45% of clay and 3-8% of a foaming agent. The decorative heat insulation composite plate provided by the invention adopts construction waste as raw materials, not only solves the problem of construction waste treatment, saves energy and protects the environment, but also can be comprehensively utilized to gain great economic profits. The decorative insulation material provided by the invention employs safe and environment-friendly raw materials, and has double functions of thermal insulation and decoration.
Description
technical field [0001] The invention relates to the technical field of building materials, in particular to a decorative thermal insulation foam ceramic composite board and a preparation method thereof. Background technique [0002] At present, the most widely used insulation system for building walls in my country is the polystyrene board insulation system. This type of system has the following disadvantages: [0003] (1) The durability is not good. The design service life of the building structure is generally 50 years, while the service life of the polystyrene board is only 10 to 15 years, which cannot meet the requirements of the building's service life; [0004] (2) Flammable. Since polystyrene board is an organic material, it will be burned rapidly in case of fire, resulting in structural damage. Therefore, it is urgent to develop non-combustible and lightweight insulation materials. [0005] On the other hand, with the development of the national economy and the acce...
