Problems solved by technology

The existing flame-retardant backsheet is mainly based on a film-coated flame-retardant backsheet. The prior art publication number is CN103262259A. By attaching a flame-retardant crystalline mineral silicate sheet to a fluoropolymer film, it can achieve Flame retardant effect, but the production process is more cumbersome and complicated, and the adhesion between the flame retardant sheet and the base material or the internal packaging layer is poor, and the weather resistance of the separate flame retardant layer is poor
However, the double-sided coated flame-retardant backsheet with ordinary flame retardants, because of the migration of flame retardants during the aging process, leads to a decrease in the adhesion level of the coating, and even the coating will fall off.
