Calcium silicate composite fireproof door core plate

Abstract

The invention discloses a calcium silicate composite fireproof door core plate, and belongs to the field of fireproof door core plates. The calcium silicate composite fireproof door core plate is characterized in that: a calcium silicate plate is compounded between two layers of inorganic soluble ceramic fiber plates, and a magnesium aluminum oxide cement layer is arranged between the inorganic soluble ceramic fiber plate and the calcium silicate plate. The fireproof door core plate body has a sandwiched composite structure formed by sticking the moisture-proof inorganic soluble ceramic fiber plate, the calcium silicate plate and the inorganic soluble ceramic fiber plate. The fireproof door core plate with the structure is characterized in that: because of the compound structure of the moisture-proof calcium silicate plate and the inorganic soluble ceramic fiber plates, the fireproof door core plate has the advantages of low volume density, high continuous high-temperature fireproof performance, energy conservation, consumption reduction, excellent sound insulation performance, high strength, high toughness, accurate size, and the like and can be easily processed; the steel plate can be easily embossed; and because all the materials are subjected to moisture-proof treatment, the fireproof door core plate has high durability.

Description

technical field [0001] The invention provides a fireproof door core board for fire prevention in civil buildings, especially a calcium silicate composite fireproof door core board. Background technique [0002] As we all know, the emergence of fire-resistant door core panels is due to people's fire-proof requirements for buildings, gradually replacing family door panels. Now the main materials of fire-resistant door core panels are rock wool, glass magnesium board, perlite board, foamed cement board, etc. These Inorganic materials are generally prone to defects such as low slag strength, low slag strength, and easy peeling under impact. In addition, because most of the materials used contain organic matter, the fire resistance performance is reduced, and the toxicity of smoke production is not up to the standard. Contents of the invention [0003] According to the deficiencies of the above existing technologies, the technical problem to be solved by the present invention i...

[0002] As we all know, the emergence of fire-resistant door core panels is due to people's fire-proof requirements for buildings, gradually replacing family door panels. Now the main materials of fire-resistant door core panels are rock wool, glass magnesium board, perlite board, foamed cement board, etc. These Inorganic materials are generally prone to slag falling, low strength, and easy to peel off under impact. In addition, because most of the materials used contain organic matter, the fire resistance performance is reduced, and the toxicity of smoke production is not up to standard.
