Abstract

The invention discloses a method for preparing a high-strength light insulating brick, belonging to the technical field of insulating brick preparation. The method comprises the following steps: firstly, the surface of aluminate cement is modified by utilizing a silane coupling agent; a silanol group is formed after an estersil group and water perform a hydrolysis reaction; pores inside an insulating brick are filled with particles; and since the binding force between two phases is greatly reinforced, a waste brick is crushed and ground to obtain waste brick powder, and the matrix structure isdensified in the process of reducing the granularity of waste brick powder particles, increasing the specific surface area and increasing the surface free energy. According to the method, a polyesterfilm is modified by utilizing quartz sand powder, the modified polyester film is coated to the surface of an insulating brick blank, and a network-shaped silicon-aluminum-oxygen compound-metakaolin is formed, and pores inside the insulating brick are effectively filled; furthermore, the filler is molten at high temperature to form a liquid phase, partial pores generated by a matrix can be filled,the heat conducting coefficient of the matrix can be reduced, and the insulating performance of the insulating brick can be further improved. The insulating brick has wide application prospect.

Description

technical field [0001] The invention discloses a preparation method of a high-strength light-weight insulating brick and belongs to the technical field of insulating brick preparation. Background technique [0002] Insulation brick, a new type of building material, is synthesized with polymer materials, and also processed with cinder and slag. It is mainly used for wall filling of buildings and buildings. It has the advantages of light weight, convenient construction, and heat preservation. It has become the main wall material of modern buildings. [0003] Insulation bricks in the existing building materials are mostly made of polystyrene-based polystyrene boards or mixed with fly ash, perlite, etc. to prepare insulation bricks. Polystyrene panels can only be used for external wall insulation, not for masonry main walls, and polystyrene is not flame retardant, so its scope of use is limited. [0004] At present, the thermal insulation materials using polystyrene board, den...
