Problems solved by technology

The current prefabricated thermal insulation wall panels are generally made of ordinary Portland cement, which has the disadvantages of slow setting and hardening, long demoulding time, and low production efficiency.
In order to speed up production efficiency, many enterprises adopt steam curing method to shorten the demoulding time, but this requires complex steam curing equipment, and the enterprise needs to invest a huge amount of money; in addition, a large amount of energy is consumed during the maintenance process, which significantly increases the production cost of the enterprise
The above reasons have greatly limited the popularization and application of the existing prefabricated thermal insulation wall panels in building industrialization, and it is urgent to develop a prefabricated thermal insulation wall panel material and its preparation method that can be quickly demoulded.

Abstract

The invention relates to a fabricated thermal-insulation wallboard material capable of realizing rapid demoulding and a preparation method of the fabricated thermal-insulation wallboard material. Thefabricated thermal-insulation wallboard material is prepared from substances in parts by weight as follows: 40-52 parts of dead burned magnesia, 20-30 parts of monopotassium phosphate, 1.5-5 parts ofborax, 15-20 parts of coal cinder, 5-8.5 parts of silica fume, 17-20 parts of water, 0.5-1.0 part of polypropylene fibers, 0.1-0.3 parts of wooden-calcium, 0.1-0.5 parts of a thickening agent, 0.1-0.4parts of an air entraining agent and 15-20 parts of ceramsite. A thermal-insulation wallboard prepared from the material with the preparation method has the advantages of short stripping time, high production efficiency, simple production equipment and low energy consumption; besides, the produced fabricated thermal-insulation wallboard is light, high in strength, good in thermal-insulation property and suitable for internal and external wallboards of modern fabricated industrialized buildings.
