Abstract

The invention relates to a construction fireproof member, and concretely relates to an environmentally-friendly and fireproof door panel and a making method thereof. The door panel is made through mixing white afrodite particles, gypsum, expanded vermiculite particles, aluminate cement, sodium hexametaphosphate, fly ash, mineral slag, and wood shavings or straw powder, and through molding. The door panel has lightweight and a fireproof function, and is in favor of realizing environmental protection due to use of recovered resources.

Description

technical field [0001] The invention relates to a building fireproof component, in particular to an environment-friendly fireproof door core board and a manufacturing method thereof. Background technique [0002] Fire doors are one of the measures for building fire separation. They are widely used in civil buildings, chemicals, machinery and other construction fields. They are especially installed in the openings of firewalls and evacuation passages, entrances and exits of stairwells, and openings of pipe wells. Effective containment of property damage from fire plays an important role. In the existing technology, the door panels of fire doors are mostly made of cold-rolled steel plates through combined welding, while the design of fire-resistant door core panels is relatively poor in flame retardancy and heat insulation, and most fire-resistant door core panels only have flame-retardant properties. However, there are technical problems such as the single function of the fi...
