preparation example Construction

[0026] This specific embodiment provides a kind of preparation method of calcium silicate board, comprises the following steps:

[0027] Iron oxide green, dispersant and water are mixed to obtain a mixed solution; the dispersant is one or both of polyethylene glycol solution and methyl amyl alcohol solution; the amount of the dispersant is the quality of the water 0.05%-5%;

[0028] Mix white material, tailings and stone powder to obtain a mixture; the white material is C 2 The fired material with S accounting for more than 80%, other components of the white material also include C 3 S, C 3 A.C 4 AF; the mass ratio of the white material, the tailings and the stone powder in the mixture is (25-30):(5-9):1; the added amount of the iron oxide green is 0.2 of the mass of the mixture %-6%;

[0029] Mixing the mixed liquid and the mixture to obtain a wet material; the water content in the wet material is 10%-20% of the mass of the mixture;

[0030] Put the wet material into a ...

Embodiment 1

[0036] This embodiment proposes a calcium silicate board, which is made by the following steps:

[0037] Dissolve a certain amount of iron oxide green in a small amount of absolute ethanol solution, and grind until dry;

[0038] Mix 1.6g of dried iron oxide green, 0.363g of polyethylene glycol solution and 24.24g of deionized water, and stir thoroughly to obtain a mixed solution;

[0039] Mix 128g white material, 32g gold sand tailings and 5g stone powder to obtain a mixture;

[0040] mixing the mixed liquid and the mixture to obtain a wet material;

[0041] Put the wet material into a tablet machine and press it into a green body with a pressure of 15MPa and a grinding tool of 10cm*10cm, dry the green body at 40°C for 5h until the water loss rate reaches 55%, and then take it out to obtain a calcium silicate substrate , named 1%-C 2 S;

[0042] Place the calcium silicate substrate in vacuum CO 2 Carbonization 24h under the environment obtains described calcium silicate b...

Abstract

The invention discloses a calcium silicate board and a preparation method thereof, belonging to the technical field of inorganic boards. The preparation method of the calcium silicate board comprises the following steps: mixing iron oxide green, a dispersing agent and water to obtain a mixed solution; mixing a white material, tailings and stone powder to obtain a mixture; mixing the mixed solution and the mixture to obtain a wet material; pressing the wet material into a green body, drying the green body at 30-60 DEG C until a water loss rate reaches 50-70%, and then taking out the green body to obtain a calcium silicate substrate; and carbonizing the calcium silicate substrate in a vacuum CO2 environment to obtain the calcium silicate board. The calcium silicate board is high in breaking strength, low in water absorption rate and high in carbonization degree.

Description

technical field [0001] The invention relates to the technical field of inorganic boards, in particular to a calcium silicate board and a preparation method thereof. Background technique [0002] With the development of human society and continuous economic progress, the combustion of fuel has caused a series of serious environmental problems. Gaseous pollution has always been regarded as one of the most serious environmental problems that threaten human existence. So far, people have taken different measures way to solve this problem. Calcium silicate board carbonization technology is a sustainable and environmentally friendly technology. It uses gaseous pollutants and has the characteristics of no secondary pollution and recyclable regeneration. [0003] Calcium silicate board has the advantages of waterproof performance, high strength, stable size, heat and sound insulation, long service life, etc. It can be used in walls, ceilings, floors, furniture and other fields. ...
