Embodiment 1

[0032] according to figure 1 As shown, take 40g of red mud, 160g of copper tailing slag, 160g of fly ash, 40g of feldspar, and 20g of bentonite, mix them by ball milling, add 32g of sodium fluorosilicate and stir evenly, then add 400g of water glass, and add 20g of water and stir evenly Finally, add 20g of hydrogen peroxide and stir for 30s, then pour it into the mold immediately; dry it at a temperature lower than 50-60°C for 24 hours and put it in the furnace for sintering; the sintering temperature is 900-1000°C, and the sintering system has strict requirements. Requirements: Room temperature-(130-150°C) heating rate is 0.8-1°C / min; (130-150°C) heat preservation 1h-3h; (130-150°C)-(600-700°C) heating rate is 1.5 -2°C / min; (600-700°C)-X (900-1000°C) heating rate is 0.5-1.2°C / min; keep warm at X (900-1000°C) for 1-2.5h, press 0.5 Cooling at a rate of -1°C / min.

[0033] The characteristics of the sample are as follows: All performance indicators have reached the national A-l...

Embodiment 2

[0036]Take 120g of copper tailings slag, 120g of fly ash, 30g of feldspar, and 15g of bentonite, mix them by ball milling, add 25g of sodium fluorosilicate and stir evenly, then add 220g of water glass, add 25g of water and stir evenly, then add 30g of aluminum powder Immediately after stirring for 30 s, it was poured into a mold for molding; the drying and sintering steps were the same as in Example 1.

[0037] The characteristics of the sample are as follows: All performance indicators have reached the national A-level standard for existing exterior wall tiles.

[0038]

Embodiment 3

[0040] Take 40g of red mud, 160g of copper tailings slag, 160g of fly ash, 40g of feldspar, and 20g of bentonite. After mixing by ball milling, add 32g of sodium fluorosilicate and stir evenly, then add 400g of water glass, and at the same time add 20g of water. Stir 50g of air bubbles and 3g of polyvinyl alcohol made of rosin soap and water at a weight ratio of 1:20 and pour it into a mold immediately; the drying and sintering steps are the same as in Example 1.

[0041] The characteristics of the sample are as follows: All performance indicators have reached the national A-level standard for existing exterior wall tiles.

[0042]

[0043] Get copper tailings slag 130g, fly ash 120g, feldspar 35g, bentonite 45g, add 48g sodium fluorosilicate and stir after ball milling and mix, add 160g of water glass after adding 64g water at the same time and stir, add by weight ratio Mix 60g of air bubbles and 1.5g of bone glue made of rosin soap and water at a ratio of 1:40 and pour it...

Abstract

The invention belongs to the technical field of building materials and particularly relates to a foamed ceramic insulation board and a preparation method thereof. The technical scheme provided by the invention is that the foamed ceramic insulation board comprises the following components in parts by weight: 100 parts of mixture, 4-15 parts of sodium fluosilicate, 50-100 parts of sodium silicate, 5-40 parts of water and 5-25 parts of foaming agent. According to the foamed ceramic insulation board, industrial waste can account for 70-85 percent. The solid waste is largely utilized, and inorganic materials are completely utilized, therefore, the national class-A non-combustible standard can be reached.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a foam ceramic insulation board prepared by using solid waste and a preparation method thereof. Background technique [0002] Since the implementation of energy-saving external wall insulation in my country, organic thermal insulation materials have always been the mainstream materials and occupy a major position in the development of the entire industry. Organic insulation materials are mainly derived from petroleum by-products, including expanded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane spray (SPU) and polystyrene particles. From a national perspective, organic external wall insulation systems occupy more than 75% of my country's current external wall insulation market. The biggest advantages of organic thermal insulation materials are light weight, heat preservation, good heat insulation, and low cost. The biggest disadvan...
