Further, the heat insulation board is a polyurethane foaming heat insulation board.
Furthermore, the flame-retardant shell is formed by pressing polyester staple fibers, polypropylene staple fibers and rock wool.
Further, the length of the adhesive plate is 5-8cm, and the width of the adhesive plate is equal to the inner diameter of the flame-retardant shell.
Further, the number of the adhesive plates is 2-4.
The utility model discloses a polyester staple fiber, polypropylene fiber staple fiber, rock wool pressure and polyurethane adhesive system form fire-retardant casing, put into fire-retardant casing with the polyurethane rigid foam that produces, fire-retardant casing is slightly wider than the polyurethane rigid foam, then to the polyurethane adhesive of beating in the space between fire-retardant casing and the polyurethane rigid foam, the sticky board prevents that the polyurethane adhesive flows to fire-retardant casing inside, help quick bonding, then bond fire-retardant layer in fire-retardant casing upper end, wherein fire-retardant layer is the same with fire-retardant casing material.
The utility model provides a beneficial effect that technical scheme brought is: the utility model discloses by fire-retardant casing, heated board, gluing board, tie coat, fire-retardant layer form compound fire-retardant heated board jointly, strengthened the fire behaviour of heated board, be fit for the production needs of current polyurethane rigid foam, compromise fire-retardant and thermal insulation performance.
