Fireproofing insulating brick and production method thereof

Abstract

The invention discloses a fireproofing insulating brick which comprises an outer frame, a filling body and a cover plate, wherein the outer frame is semi-closed brick body shape; the inside of the outer frame is a cavity structure; the filling body is placed in the cavity; and the cover plate is matched with the opening surface of the outer frame and is adhered to the outer frame through a high temperature adhesive. The fireproofing insulating brick has the beneficial effects that a rigid fireproofing material is used for making a thin wall coat, and a light insulating fireproofing material is sealed in the close cavity, thus the brick has the rigidity of the fireproofing brick and simultaneously the maximum porosity of the light insulating fireproofing material is maintained so that the insulation effect of the insulating material is maximized, and the light material is protected from not being lost, and the production cost is lowered.

Description

technical field [0001] The invention relates to a heat insulating brick, in particular to a refractory heat insulating brick and a manufacturing method thereof. Background technique [0002] At present, in order to pursue a greater thermal insulation effect in the known thermal insulation refractory materials, the purpose of reducing thermal conductivity is generally achieved by increasing the porosity and void ratio of the material. Large porosity and void ratio will inevitably lead to relatively low strength of the material, and it is easy to be damaged and lost during use, which affects the service life of the material. In actual production, in order to achieve a certain strength, part of the porosity and porosity have to be lost, which reduces the heat insulation effect. Moreover, the usual practice of heat-insulating lightweight refractory materials is: adding a binder to form by pressure or vibration, and some have to be sintered at high temperature, which is relative...

Large porosity and porosity will inevitably lead to relatively low strength of the material, and it is easy to be damaged and lost during use, which affects the service life of the material

In actual production, in order to achieve a certain strength, part of the porosity and porosity have to be lost, which reduces the heat insulation effect.

Moreover, the usual practice of heat-insulating lightweight refractory materials is: adding a binder to form by pressing or vibrating, and some have to be sintered at high temperature, and the cost is relatively high.
