Embodiment Construction
[0019] Such as figure 1 As shown, a high-temperature-resistant fire-resistant door core panel of the present invention includes a door core panel body; the upper and lower surfaces of the door core panel body are compounded with a layer of non-woven fabric 2.
[0020] Preferably, the door core panel body is a foamed door core panel body 1.
[0021] Preferably, the thickness of the non-woven fabric 2 is 0.5-0.8 mm.
[0022] The foamed door core board body 1 is a kind of light fireproof and heat-preserving material made by foaming magnesite slurry made by physical foaming method, and then injecting the foaming magnesite slurry into a mold, so according to the shape of the door Different molds can be selected to make special-shaped doors with a wide range of uses.
[0023] The working process of this example: when the present invention is put into the door panel, since the upper and lower surfaces of the foamed door core panel are compounded with non-woven fabric 2, its glue absorption ...

Abstract
The invention provides a high-temperature resistant fireproof door core plate. The high-temperature resistant fireproof door core plate comprises a door core plate body, wherein a layer of non-woven cloth is compounded on the upper and lower surfaces of the door core plate body; and the door core plate body is a foamed door core plate body. The high-temperature resistant fireproof door core plate has the beneficial effects that: as the door core plate body is molded by foaming and has hollow air bubbles therein, heat is conducted and transferred more slowly, and stronger high-temperature resistance of the foamed door core plate body and long service life are achieved; as the foamed door core plate body is not formed through integral pressing, the foamed door core plate can be made into an abnormal-shape door and has wide use range; as the non-woven cloth layers are compounded at the upper and lower surfaces of the foamed door core plate body, and the glue absorbing property is strong, the fireproof core plate and the door plate are stuck more firmly; and the high-temperature resistant fireproof door core plate has the advantages of a simple structure, low cost, high intensity and the like.
Description
Technical field [0001] The invention relates to a door core board, in particular to a high temperature resistant and fireproof door core board. Background technique [0002] With the rapid development of various industries in China and the gradual expansion of the field of fireproof building materials, the non-combustibility technical performance of the fireproof door core plate is still a blank in China. As we all know, fire doors made of core panels of fire doors can omit frame support, simplify the production process of fire doors, improve production efficiency, and reduce manufacturing costs. However, traditional fire door core panels are made of an integrally formed fire-resistant and heat-resistant composite material. The use of fire-resistant and heat-resistant composite materials leads to high cost and overall weight of the fire door, and it cannot be formed according to the shape of the door. Shaped door core board. Summary of the invention [0003] The problem to be so...
