Flame-retardant core material for aluminum-plastic panel and preparation method for flame-retardant core material

摘要: The invention discloses a flame-retardant core material for an aluminum-plastic panel and preparation method the material. comprises following components in weight percentage: 12-20 percent of elastomer, 0-3 compatilizer, 73-84 halogen-free fire retardant, synergist, 0.15-0.3 coupling agent, 0.2-1 antioxygen, 2-3 lubricant 0.5-0.9 other additives. plastic fireproof not only has characteristics low cost, no halogen, smoke, flame resistance, high hot-pressing bonding strength, bendability coilability like but also advantage good mechanical behavior. When composite is produced by adopting disclosed invention, molding process performance good, standard requirement continuous industrial production line can be met. combustion completely meet A2-level GB20286-2006 regulation.
