(1)Fireproof panels also can be called fire rated aluminum composite panel or fire resistant aluminum composite panel. It adopts flame-retardant core material, and the combustion performance of the fireproof panels reaches the refractory grade (class B1) or non-combustible grade (class A).
(2)At the same time, other performance indicators must also meet the technical specifications of aluminum composite panels.
(1) The production process of fireproof panels core material
The fireproof aluminum-plastic composite core material is made of polyethylene as the main raw material, adding halogen-free environmentally-friendly flame retardant, and adopting continuous activation equipment to refine the surface of the composite, and then adding flame retardant synergist and other additives. After fully mixing and plasticizing, the particles are extruded.
(2)The characteristics of fireproof core material
The halogen-free fireproof aluminum-plastic plate core material is grayish white or white granules, which has the advantages of environmental protection, light weight and easy processing. It conforms to the development trend of international flame retardant materials and can meet the requirements of the building decoration industry. The fire rating reaches A grade or B. Level, fully meet the requirements of the aluminum composite panel production industry.
B1 grade plastic core:
It contains 55% – 55% flame retardant, the main ingredients are aluminum oxide (Al₂O₃) and magnesium oxide (MgO) ;
A2 grade fireproof aluminium composite sheet plastic core material :
It Contains 88% – 90% of the flame retardant, the main ingredients are aluminium hydroxide(Al(OH)3) and magnesium hydroxide (Mg(OH)2) ;
For B1 grade fireproof aluminum composite sheet:
When B1 grade panels are put on fire, it can be catched on fire after 5 minutes, and the fire will extinguish after 10 seconds when the fire leave the panels.
A2 grade fireproof aluminium composite sheet:
It can be catched on fire after 20 minutes, and the fire will extinguish immediately when the fire leave the panels.
Testing indicators and requirements of B1 grade fireproof panels:
Testing indicators and requirements of A2 grade fireproof panels:
Alucoworld aluminum composite panel has always been a leader in the domestic aluminum composite panel industry, at present, only very few acp manufacturers can produce A2 grade fire rated aluminium composite panels in China.
The good news is that professional Alucoworld ACP manufacture can offer you mature A2 grade fireproof acp.
