A new type of fire door leaf with anti-deformation and fireproof and heat insulation properties

Abstract

This utility model discloses a novel fire door leaf with anti-deformation and fireproof / heat-insulating properties, comprising a perlite fireproof core, solid wood door panels, PVC wood veneer edge banding, double-sided fireproof panels, double-sided MDF decorative panels, and PVC fireproof door decorative panels. Multiple solid wood door panels surround the four sides of the perlite fireproof core, and PVC wood veneer edge banding surrounds the four sides of the solid wood door panels. The double-sided fireproof panels are located on the sides of the perlite fireproof core, and the double-sided MDF decorative panels are symmetrically arranged on the sides of the double-sided fireproof panels. The PVC fireproof door decorative panels are located on the sides of the double-sided MDF decorative panels. This utility model optimizes the internal structure of the fire door leaf, enabling the fire door to resist deformation while improving its fireproof and heat-insulating performance. It not only possesses excellent sealing, fireproof, and heat-insulating properties, but also significantly enhances its structural stability and aesthetic appearance, making it suitable for various scenarios.
