TECHNICAL FIELD

[0001] The present application relates to the field of porcelain aluminum plate, in particular to a fireproof high-temperature-resistant porcelain aluminum plate. BACKGROUND

[0002] The porcelain aluminum plate is a new type of building appearance material, which is used in the interior and exterior decoration wall of the subway station. The existing porcelain aluminum plate can achieve the effect of fireproof and high-temperature-resistant.

[0003] Before the existing porcelain aluminum plate is installed on the wall, the fireproof and high-temperature-resistant plate is installed in the back cavity of the porcelain aluminum plate in advance. In order to effectively install the fireproof and high-temperature-resistant plate into the cavity, the cross section of the plate needs to be slightly smaller than the cross section of the cavity. However, this will result in a certain gap between the plate and the cavity after the plate is installed in the cavity. When the porcelain aluminum plate is installed on the wall and encounters high temperature in the fire, the plate will burn due to the high temperature reaching the ignition point, and the gap space provides oxygen components as an oxidizing agent for the plate, which causes the plate to burn inside the porcelain aluminum plate, resulting in the destruction of the porcelain aluminum plate from the inside. Therefore, we propose a fireproof and high-temperature-resistant porcelain aluminum plate. SUMMARY

[0004] The purpose of the present application is to provide a fireproof and high-temperature-resistant porcelain aluminum plate that can fill the gap between the cavity of the porcelain aluminum plate and the fireproof plate, to solve the problems raised in the background art.
