An inorganic permeable fireproof insulation board

Abstract

The invention relates to an inorganic permeable fireproof thermal insulation board, belonging to the field of building materials. The inorganic permeable fireproof thermal insulation board is characterized by comprising a thermal insulation board body; the thermal insulation board body comprises a heat insulating layer and an interfacial transition layer; the heat insulating layer comprises a thermal insulation base plate, and a nano inorganic material permeates into the thermal insulation base plate; the interfacial transition layer is prepared from an organosilicon waterproofing agent and apermeable crystalline waterproofing agent; the thickness is 1-3mm. The heat insulating layer is prepared from the thermal insulation plate, the surface of which is coated with foamable particles, andthe nano inorganic material, so that not only is the requirement of thermal insulation met, but the aim of fire protection is also achieved; the interfacial transition layer is prepared from the organosilicon waterproofing agent and the permeable crystalline waterproofing agent; by adjusting the gradation, the interfacial transition layer has better adhesive force with the heat insulating layer onthe basis of meeting the waterproof performance. The inorganic permeable fireproof thermal insulation board has the advantages of being simple in production process and high in mechanical property, having the functions of heat insulation and fire protection at the same time, and the like, thus being widely applied to the fields such as exterior wall external insulation and roof insulation.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to an inorganic permeable fireproof and thermal insulation board. Background technique [0002] With the improvement of building energy-saving standards, traditional inorganic thermal insulation materials are difficult to meet the thermal performance requirements. In the process of practical application, inorganic thermal insulation materials have exposed many problems. Rock wool is the most common thermal insulation material in external wall insulation systems. , due to its poor hydrophobic performance, rock wool loses its original thermal insulation performance after washing, forming a cold and thermal bridge. Organic materials can meet energy-saving requirements, but their fire resistance is poor. In recent years, fire accidents caused by the use of organic insulation materials have occurred frequently. For example, the fire in the CCTV building was caused by the use...

Problems solved by technology

[0005] In addition, the installation method of the traditional insulation board has safety hazards such as loose fixation and easy peeling off

Especially when the ambient temperature changes, the stress generated inside the board body cannot be offset due to thermal expansion and contraction; when receiving external impact, the thermal insulation board installed in the traditional way will have obvious peeling phenomenon
