Description

Technical Field

[0001] The utility model relates to the technical field of fireproof doors, in particular to a door building material structure with both thermal insulation and fireproof performance. Background Art

[0002] A fire door is a door that has a separation and protection function, and can prevent the spread of fire and smoke. It is installed in a building. In the event of a fire, it can prevent the spread of fire for a certain period of time and assist in the evacuation of people. It plays an important role in suppressing the spread of fire and protecting the safe evacuation of people.

[0003] Currently, the most commonly used internal building material for fire-resistant doors on the market is perlite board. This board is a sheet made by pressing a mixture of expanded perlite particles and an inorganic binder. While it offers thermal insulation and fire resistance, it can even explode in high-temperature environments during a fire. Its thin structure has limited durability, a short resistance to high temperatures, and deformation that makes it unable to prevent fire and smoke, hindering evacuation. Therefore, a door building material with enhanced structural strength and thermal insulation properties has been proposed. Utility Model Content
