Problems solved by technology

[0002] At present, most of the lightweight foam insulation and sound insulation materials produced by normal temperature curing are magnesium cement foam materials containing magnesium oxide and magnesium chloride as base materials. The components are basically filled with ordinary fly ash. The ash content is low, the cost is high, it is not water-resistant, easy to deform, it is an air-hard material, unstable, and its strength gradually decreases with the increase of the service life. It is not suitable for use in humid areas and open air, and is not suitable for external walls. Material
Therefore, the building materials market is subject to certain restrictions by national policies

Embodiment 1

[0039] Put the high activity fly ash into the ball mill to grind, the fineness is 5500cm specific surface area 2 / g.

[0040] Formula: 30 kg of finely ground high-activity fly ash, 6 kg of sulfur-aluminum cement, 0.6 kg of raw gypsum powder, and 24 kg of water.

[0041] Put the above ingredients into the blender in order and stir for 2 minutes, stir evenly to make a slurry for later use.

[0042] Physical foaming: Put 0.3 kg of rosin resin liquid foaming agent and 3 kg of water into the mixer and stir it mechanically for foaming before use.

[0043] Put the slurry and the foam in a mixer at a volume ratio of 1:1 and stir evenly, then pour it into a 1000×1000×90mm mold, demould it after 8 hours, put it in a normal temperature curing room for 25 days, and then mold it into a finished product.

Embodiment 2

[0045] Put the high activity fly ash into the ball mill to grind, the fineness is 5500cm specific surface area 2 / g.

[0046] Formula: 25 kg of finely ground high-activity fly ash, 2.5 kg of sulfur-aluminum cement, 0.5 kg of raw gypsum powder, and 14 kg of water.

[0047] Put the above ingredients into the blender in order and stir for 2 minutes, stir evenly to make a slurry for later use.

[0048] Physical foaming: Put 0.3 kg of animal protein foaming agent and 4 kg of water into the mixer and stir it mechanically for foaming before use.

[0049] Put the slurry and foam in the mixer at a volume ratio of 1:1.5 and stir them evenly, pour them into a 1000×1000×60mm mold, demould after 8 hours, put them in a curing room at 20°C-35°C for 30 days, and then take shape That is the finished product.

Embodiment 3

[0051] Put the highly active fly ash into the ball mill to grind, the fineness is 6500cm specific surface area 2 / g.

[0052] Formula: 25 kg of finely ground high-activity fly ash, 22.5 kg of high-alumina cement, 2.5 kg of raw gypsum powder, and 50 kg of water.

[0053] Put the above ingredients in a blender in order and stir for 4 minutes, stir evenly to make a slurry for later use.

[0054] Physical foaming: Put 0.6 kg of sodium dodecylbenzene sulfonate solution and 4.8 kg of water into the mixer and stir it mechanically for foaming before use.

[0055] Put the slurry and the foam in the mixer at a volume ratio of 4:1 and stir, pour it into a 1000×1000×60mm mold after stirring evenly, demould it after 8 hours, put it into a curing room at 35°C-60°C, 20 The finished product is formed after the day.

Abstract

The present invention is one kind of no-baking light foamed heat insulating and sound isolating material and its production process. The no-baking light foamed heat insulating and sound isolating material has high activity fly ash, which is produced based on one other patent of the present inventor, as basic material and some other components. It has high water resistance, high strength, high fireproof performance and high stability.

Description

technical field [0001] The invention relates to the field of foaming thermal insulation and sound insulation building materials, in particular to a non-burning lightweight foam thermal insulation and fireproof material made of fly ash collected from boiler exhaust smoke of coal-fired power plants and its production method. Background technique [0002] At present, most of the lightweight foam insulation and sound insulation materials produced by normal temperature curing are magnesium cement foam materials containing magnesium oxide and magnesium chloride as base materials. The components are basically filled with ordinary fly ash. The ash content is low, the cost is high, it is not water-resistant, easy to deform, it is an air-hard material, unstable, and its strength gradually decreases with the increase of the service life. It is not suitable for use in humid areas and open air, and is not suitable for external walls. Material. Therefore, the building materials market i...
