Problems solved by technology

[0003] Organic insulation materials are widely used in building materials due to their light texture and good sound-absorbing and heat-insulating properties. However, organic materials have the disadvantage of being flammable, and they will emit a lot of toxic fumes when burned, especially extruded boards and foams. Plates, etc., will melt and deform at about 80°C. Once a fire occurs, these materials will serve as combustion aids and promote the rapid spread of the fire.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a flame-retardant building thermal insulation material. Background technique [0002] Building thermal insulation materials refer to materials with high resistance to heat flow, that is, materials that prevent indoor heat from dissipating from the inside to the outside. If they are combined with the wall, both wall materials can be saved and thermal insulation can be achieved. These materials usually have a large number of closed voids inside, so they have excellent thermal insulation effect. Building thermal insulation materials can be divided into three categories: external wall thermal insulation materials, internal wall thermal insulation materials and roof thermal insulation materials according to their use positions, and can also be divided into three categories: organic materials, inorganic materials and composite materials according to their internal components...
