Fireproof door with fireproof heat insulation structure

Abstract

The fireproof door with the fireproof heat insulation structure comprises a metal door frame, a door hinge and a door leaf, thermochromic glass is installed on the door leaf, the door leaf comprises a core plate, a glass installation opening is formed in the core plate, pipeline embedding grooves are formed in the outer walls of the two sides of the core plate, cooling pipelines are arranged in the pipeline embedding grooves, and the glass installation opening is communicated with the cooling pipelines. And the cooling pipeline is filled with cooling liquid. The cooling pipeline is installed in the door leaf, the cooling liquid is contained in the cooling pipeline, and the plate-shaped heat conduction material filling layer made of the heat conduction material in a compressed mode is matched, so that heat of the fireproof panel on the outer side of the door leaf can be absorbed, and the high temperature resisting time of the door leaf is prolonged; according to the thermochromic glass, the transparent thermochromic material film can change the color according to the change of the external temperature through the transparent thermochromic material film, and the transparent thermochromic material film is arranged in the transparent glass and is difficult to damage, so that the cost is reduced.
