Embodiment 1
[0038] The reference of the polyurethane modified rock wool thermal insulation decorative board in this embodiment figure 1 . Including the decorative surface material 6 for decoration and fire prevention, the rock wool 4 that is applied on the back of the decorative surface material and combined with the decorative surface material, and the polyurethane that combines the decorative surface material 6, rock wool 4 and interface coil material 8 into one The foam layer 13, and the interface coil 8 attached to the other side of the polyurethane foam layer 13, the decorative surface material 6 adopts a thin stone veneer, and the thickness of the rock wool 4 is 5cm. The specific operation steps of the production process are:
[0039]Adopt a continuous production line consisting of foaming machine 1, conveying track II3, preliminary bonding mechanism, conveying track I16, double track laminating machine mechanism, uncoiler 9, and pouring mechanism, and set conveying track II3, uncoi...
Embodiment 2
[0041] The polyurethane modified rock wool insulation decorative board of this embodiment refers to the attached figure 2 . The difference between this embodiment and Embodiment 1 is that the decorative surface material 6 adopts an acrylic veneer, and the back of the acrylic board is compounded with three rock wool 4, the thickness of the rock wool 4 is 6cm, and the interval between each rock wool is 3cm. The specific operation steps of the process are:
[0042] Set the linkage speed of conveyor track II3, conveyor track I16, double track laminator mechanism, and uncoiler 9 to 4.5m / min, place a 1.2m×0.6m acrylic veneer on the conveyor track I16, and place three 1 m Rock wool 4 × 0.15m is placed on the conveyor belt II 3, and the pressure of the gun head 7 of the glue spraying machine is adjusted to 16MPa, and the flow rate is 208g / s. In the first process, the adhesive is evenly poured on the acrylic veneer to complete the preliminary bonding of the rock wool 4 and the acryl...
Embodiment 3
[0044] The polyurethane modified rock wool thermal insulation decorative board of this embodiment differs from that of Embodiment 1 in that the decorative surface material 6 is made of flexible stone, and the thickness of the rock wool 4 is 10 cm. The specific operation steps of the production process are as follows:
[0045] Set the linkage speed of conveying crawler II3, conveying crawler I16, double crawler lamination mechanism, and coil uncoiling mechanism 9 to 10m / min, place a 0.9m×0.73m flexible stone on the conveying crawler I16, and place a 0.75m×0.6 M rock wool 4 is placed on the conveyor belt II 3, and the pressure of the gun head 7 of the glue spraying machine is adjusted to 10MPa, and the flow rate is 500g / s. In the first process, the adhesive is evenly poured on the flexible stone to complete the preliminary bonding of the rock wool 4 and the flexible stone. In the second process, the polyurethane composite material with a material temperature of 40 ° C is evenly p...
