Fireproof door core plate

Abstract

The invention discloses a fireproof door core plate with all indexes of respectively reaching national standards, comprising a base plate which adopts expanded perlite as the main material; and the upper surface and the lower surface of the base plate are respectively compounded with at least one layer of lattice cloth, and the outer side of the lattice cloth is coated with a refractory material so as to form an upper refractory layer and a lower refractory layer. The fireproof door core plate is respectively compounded with the lattice cloth on the upper surface and the lower surface of the base plate which adopts expanded perlite as the main material, and coats the refractory material at the outer side of the lattice cloth, therefore, the indexes of the strength and the fireproof burning performance of the fireproof door core plate respectively reach the national standards, thus leading all the indexes to reach the national standards. Therefore, the fireproof door can be manufactured by adopting the fireproof door core plate, thus being capable of simplifying the manufacturing process, improving the production efficiency and reducing the manufacturing cost.

Description

technical field [0001] The invention relates to a fireproof board, in particular to a fireproof door core board. Background technique [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 kind of door core board is mainly made of expanded perlite, because its strength and fireproof combustion performance indicators have not reached the national standard, and it cannot be used as a door core board for fire doors. Therefore, the current fire doors are mainly made by traditional techniques, that is, the fire doors are made by means of skeleton support and filling materials. The ma...

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 a door core board with expanded perlite as the main material. Because its strength and fireproof performance indicators fail to meet the national standards, it cannot be used as a door core board for fire doors.

Therefore, the current fire doors are mainly made by traditional techniques, that is, the fire doors are made by skeleton support and filling materials. The manufacturing process is complicated, the production efficiency is low, and the production cost is high.
