Embodiment 1

[0014] This embodiment provides a fireproof building composite board, such as figure 1 , including a body 1, a housing chamber 2 is provided in the body 1, an exhaust port 21 is opened on the top of the housing chamber, and the exhaust port 21 is covered with a metal cover sheet 3; the housing chamber 2 is filled with a mass ratio of 1 : 1 sodium bicarbonate powder and citric acid powder; a PVC film cavity 4 (enclosed by PVC film) is also placed between the sodium bicarbonate powder and the cover sheet, and the PVC film cavity is filled with water; the PVC film cavity Closely attached to the cover sheet; the cover sheet 3 is provided with air holes 31 arranged in an array.

[0015] Further, the cover sheet is embedded in the accommodation cavity; the cover sheet is in interference fit with the accommodation cavity.

Embodiment 2

[0017] This embodiment provides a fireproof building composite board, the structure of which is consistent with that of Embodiment 1.

[0018] In particular, the accommodating cavity of this embodiment is also filled with superabsorbent resin powder and activated carbon powder, and the mass ratio of superabsorbent resin, activated carbon powder and sodium bicarbonate powder is 0.2:1:7. In this embodiment, the superabsorbent resin powder is an acrylate superabsorbent resin.

Embodiment 3

[0020] This embodiment provides a fireproof building composite board, the structure of which is consistent with that of Embodiment 2. Particularly, the accommodating cavity described in the present embodiment is also filled with a stabilizer, and the stabilizer includes 4 parts of nano-gold rods and 13 parts of nano-titanium dioxide by mass; the mass ratio of the stabilizer and sodium bicarbonate powder is 1: 700. .

Abstract

The invention discloses a fireproof building composite board, which comprises a body, and a housing cavity is arranged in the body, and an exhaust port is opened on the top of the housing cavity, and the exhaust port is covered with a metal cover sheet; the housing cavity is filled with mass ratio It is 1:1 sodium bicarbonate powder and citric acid powder; a PVC film cavity is also placed between the sodium bicarbonate powder and the cover sheet, and the PVC film cavity is filled with water; the PVC film cavity is closely attached to the cover sheet; There are air holes arranged in an array. Once the temperature of the metal cover plate is too high and the PVC film cavity is broken, sodium bicarbonate will react with water and citric acid to decompose the carbon dioxide gas and flood the indoor environment, and actively extinguish the fire by reducing the oxygen content.

Description

technical field [0001] The invention relates to a building composite board, in particular to a fireproof building composite board. Background technique [0002] Composite panels are commonly used components in the construction field. They are generally composed of various materials, such as recombined wood, polymer materials, metals, etc., so that they can obtain various functions such as fire prevention, moisture resistance, and sound insulation. Although the existing composite boards can obtain flame retardant effects by adding a composite layer of fireproof materials, what they can achieve is only that the composite boards themselves do not burn, and cannot effectively extinguish fires. Contents of the invention [0003] In view of this, the present invention provides a building composite board that can actively extinguish fire. [0004] The purpose of the present invention is achieved through the following technologies: a fireproof building composite panel, including ...
