Fireproof door core plate

Abstract

The invention relates to a fireproof plate, in particular to a fireproof door core plate. The invention discloses the energy-saving, environment-protection and light-weight fireproof door core plate with the advantages that the energy is saved, the environment is protected, nontoxicity and harmlessness are realized on human bodies, the fireproof and heat insulation performance is good, the sound absorption effect is good, the intensity is high, the service life is long, and the cost is low. The invention also provides a manufacture method of the door core plate, and the manufacture method has the advantages that the process is simple, and the flow process is short. The fireproof door core plate is made from following materials in parts by mass: 100 parts of magnesium oxide, 40 to 50 parts of magnesium chloride, 30 to 40 parts of water, 0.3 to 1 parts of modifying agents, 0.3 to 0.5 parts of foaming agents and the like.

Description

Technical field: [0001] The invention relates to a fireproof board, in particular to a fireproof door core board. technical background: [0002] As we all know, fire doors made of fire door core panels can save the skeleton support, simplify the production process of fire doors, improve production efficiency, and reduce manufacturing costs. However, as far as the current two fire door core panels are concerned, the first one is made of aluminum silicate wool as the main material. Because its smoke toxicity index does not meet the national standard, it has been banned from use; The other is the door core board with expanded perlite as the main material. Due to the poor strength of perlite itself, after bonding with the steel plate or multi-layer board, the processing deformation of the thin steel plate, heat deformation, and collision deformation and other factors , It is easy to cause the core board of the fire door to crack, thus affecting the overall performance of the fi...

However, as far as the current two fire door core panels are concerned, the first one is made of aluminum silicate wool as the main material. Because its smoke toxicity index does not meet the national standard, it has been banned from use; The other is the door core board with expanded perlite as the main material. Due to the poor strength of perlite itself, after bonding with the steel plate or multi-layer board, the processing deformation of the thin steel plate, heat deformation, and collision deformation and other factors , It is easy to cause the core board of the fire door to crack, thus affecting the overall performance of the fire door

After the multi-layer board is bonded with the core board made of perlite, the core board is easily broken by external impact during transportation and installation. In the event of a fire, when the multi-layer board is burned out, the fire door will automatically Falling apart loses its fire protection effect
