Problems solved by technology

[0005] For a long time, the comprehensive utilization of water-quenched slag has been a worldwide problem. Although a lot of research has been done on the comprehensive utilization of water-quenched slag at home and abroad, due to various technical and economic reasons, most of them have not been put into industrial realization.
[0006] In summary, there have been reports on the production of cement, wall bricks, and road materials using water-quenched slag as auxiliary raw materials, but there has been no report on the use of water-quenched slag as the main raw material for the production of aerated blocks

Embodiment Construction

[0023] A method for preparing a high-strength building insulation board, the method comprising the following steps:

[0024] 1), process 12-15 parts of fly ash

[0025] The fly ash with a lower magnetic field strength is magnetically separated by a magnetic separator, and then the fly ash after magnetic separation is ground to 1200 mesh with an ultrafine mill; the fly ash after magnetic separation is mixed with 10-12 parts of furnace ash, 6- 8 parts of phosphogypsum, 12-14 parts of volcanic rock fiber, 28-30 parts of water, and 5-7 parts of hydroxyethyl cellulose are mixed to make anti-cracking slurry, which is set aside;

[0026] 2) After the water-quenched slag is finely ground, take 15-25 parts of water-quenched slag, 24-27 parts of cement, 3-5 parts of foam stabilizer, 6-8 parts of adhesive, and 4.5-6.5 parts of polystyrene Ethylene foam plastic and 40-50 parts of water are mixed to prepare thermal insulation slurry;

[0027] 3) Mix the thermal insulation slurry and anti...

Abstract

The invention discloses a preparation method of a high-strength building thermal insulation board. The preparation method comprises the following steps of 1, treating 12-15 parts of fly ash, carrying out magnetic separation by a magnetic separator to obtain fly ash with low magnetic field intensity, and carrying out superfine grinding on the fly ash subjected to magnetic separation to obtain power of 1200 meshes, and 2, mixing the fly ash subjected to magnetic separation, 10-12 parts of stove ash, 6-8 parts of phosphogypsum, 12-14 parts of volcanic rock fibers, 28-30 parts of water and 5-7 parts of hydroxyethyl cellulose to obtain anti-cracking slurry. The preparation method has a large water-quenched slag use amount, saves energy, is environmentally friendly, relieves water-quenched slag stacking storage-caused environmental pollution and provides a novel raw material for a hollow brick.

Description

[0001] technical field [0002] The invention relates to the field of new building materials, in particular to a method for preparing a high-strength building heat insulation board. [0003] Background technique [0004] Water-quenched slag is the product of broken glass, furniture, etc., and a large amount of water-quenched slag is produced in my country every year. These water-quenched slag need to occupy a large amount of storage space, cannot be decomposed, and the recycling cost is very high. [0005] For a long time, the comprehensive utilization of water-quenched slag has been a worldwide problem. Although a lot of research has been done on the comprehensive utilization of water-quenched slag at home and abroad, due to various technical and economic reasons, most of them have not been put into industrial realization. [0006] In summary, there have been reports on the production of cement, wall bricks, and road materials with water-quenched slag as auxiliary raw mate...
