Problems solved by technology

However, organic foam plastic insulation materials are extremely flammable, and the fire spreads rapidly when burning, accompanied by a large amount of poisonous gas and smoke, which brings serious difficulties to fire fighting and rescue work, causing casualties and property losses
At the same time, this kind of insulation material also has disadvantages such as easy aging, poor dimensional stability, and low bonding strength with surface materials.

Description

technical field [0001] The invention belongs to the technical field of new wall materials, and relates to an external thermal insulation board of an external wall with a fireproof function produced from expanded vitrified microspheres and fly ash as main raw materials. Background technique [0002] The advent of the energy crisis and the implementation of building energy-saving policies have promoted the rapid development of wall insulation materials. At present, the outer wall enclosure structure of buildings mostly adopts the outer wall external insulation board system with organic foam plastics such as polystyrene foam plastics and polyurethane stearic foam plastics as thermal insulation materials. However, organic foam plastic insulation materials are extremely flammable. When burning, the fire spreads rapidly, accompanied by a large amount of poisonous gas and smoke, which brings serious difficulties to fire fighting and rescue work, causing casualties and property loss...
