An inorganic foam insulation board prepared from construction waste

Abstract

The invention discloses an inorganic foaming heated board prepared by using building waste. The heated board is prepared by taking building waste powder as a major raw material and adding cement by means of foaming and molding. The inorganic foaming heated board provided by the invention has the advantages of low density, low thermal conductivity, high firmness performance, low engineering cost, excellent sound insulating effect and environmental protection performance, and reaches a national A1 grade fireproof standard. The inorganic foaming heated board provided by the invention serving as a building energy-saving material has remarkable advantages when applied in the field of building outer wall thermal insulation technology.

Description

technical field [0001] The invention relates to the technical field of building energy-saving material development and building exterior wall insulation, in particular to an inorganic foam insulation board prepared from construction waste. The inorganic foam insulation board has low density, small thermal conductivity, good stability, and low cost. Low, with excellent sound insulation and environmental performance, and meet the national A1 fire protection standards. Background technique [0002] Climate warming and energy shortage have become two serious challenges to global sustainable development. In the next few decades, building energy consumption will become the main growth point of energy consumption, including energy consumption generated during building construction (building materials, building equipment, building construction, etc.) and energy consumption generated during building use (living energy consumption, heating and air conditioning, etc.). According to s...

Problems solved by technology

At present, the most commonly used measure for thermal insulation is to bond thermal insulation panels on the exterior wall. However, most of the current external wall insulation panels in my country use flammable thermal insulation materials. Fires caused by the extensive use of such materials occur from time to time, leading to building fires. Rapid, difficult to extinguish, and a large amount of toxic smoke released during combustion is an important cause of casualties
