Description

Technical Field

[0001] This utility model relates to the field of honeycomb filter composite panel technology, and in particular to an aluminum honeycomb core composite panel. Background Technology

[0002] Existing aluminum honeycomb core composite panels are lightweight and high-strength composite materials, which are made of two sturdy panels (such as aluminum plates, stainless steel plates, carbon fiber plates, etc.) and an aluminum honeycomb core material in the middle, through adhesive bonding or hot pressing processes.

[0003] However, when used, ordinary composite boards do not have fireproof and waterproof effects. When encountering high-temperature fires, they are easily penetrated by flames and cannot effectively block heat and flames, causing the fire to spread rapidly and not buy enough time for personnel evacuation and fire rescue. When exposed to the outdoors or in humid environments for a long time, they are easily corroded by rain and moisture, causing the surface to rust and corrode, affecting the appearance and service life. Utility Model Content

Through the ceramicized silicone rubber fireproof coating, it can be ceramicized at high temperature to form a hard fireproof barrier. Through the first fireproof layer of phenolic resin and the second fireproof layer of ceramic fiber cloth, it can achieve double high temperature resistance and block the penetration of flames and heat into the interior. Combined with the inner layer of aluminum foil, it reflects heat radiation and delays the spread of fire, giving the composite panel body a super fireproof performance. Through the outer layer of fluorocarbon coated aluminum plate, the surface of the composite panel body is highly hydrophobic and resistant to rain corrosion. Combined with the waterproof layer of PTFE film, it can maintain stability when the composite panel body is exposed to the outdoors or humid environment for a long time, giving the composite panel body excellent waterproof and moisture-proof performance.
