Preparation method of high-strength building insulation board

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

technical field [0001] The invention relates to the field of new building materials, in particular to a method for preparing a high-strength building heat insulation board. Background technique [0002] 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. [0003] 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. [0004] In summary, there have been reports on the production of cement, wall bricks, and road materials with water-quenched slag as auxiliary raw materials, but there ha...

[0002] 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, and cannot be decomposed, so the cost of recycling is very high.

[0003] 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.

[0004] 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
