Problems solved by technology

Comparing these two different types of thermal insulation materials for thermal insulation decorative panels, although the former has good flame retardancy, it has a high water absorption rate and needs to be waterproofed; secondly, rock wool has low strength and is not suitable for use in this way. Materials with heavy weight per unit area such as stone are used as thermal insulation decorative panels for facing; thirdly, rock wool has a high thermal conductivity, and compared with polyurethane rigid foam, a thicker rock wool layer is required to achieve the corresponding thermal insulation effect; In terms of flame retardant performance, the effect is average, but it makes up for the defects of high water absorption, low strength and high thermal conductivity of rock wool
In addition, during the construction of these two integrated boards, rock wool and polyurethane need to be treated separately on the interface before they can be mounted on the wall, and it is difficult to achieve continuous production by using the ordinary paste method, and the production efficiency, cost and energy consumption are still very large. room for improvement

Embodiment 1

[0038] Reference to the polyurethane modified rock wool thermal insulation decorative board of this embodiment figure 1 . Including the decorative surface material 6 for decoration and fire prevention, the rock wool 4 that is attached to the back of the decorative surface material and the decorative surface material is integrated, and the decorative surface material 6, the rock wool 4, and the interface coil 8 are combined into one polyurethane 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 uses a thin stone veneer, and the thickness of the rock wool 4 is 5 cm. The specific operation steps of the production process are:

[0039] Adopt a continuous production line consisting of foaming machine 1, conveyor belt Ⅱ 3, preliminary bonding mechanism, conveyor belt Ⅰ 16, double-track laminator mechanism, decoiler 9, pouring mechanism, set conveyor belt Ⅱ 3, uncoiler 9, conveyor belt Ⅰ16. The link...

Embodiment 2

[0041] Reference Attachment for the polyurethane modified rock wool thermal insulation decorative board of this embodiment figure 2 . This embodiment is different from embodiment 1 in 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 6 cm, and the interval between each rock wool is 3 cm. The specific process steps are:

[0042] Set the linkage speed of conveyor belt Ⅱ3, conveyor belt Ⅰ16, double-track laminator mechanism, and decoiler 9 to 4.5m / min. Place 1.2m×0.6m acrylic veneer on the conveyor belt Ⅰ16 and place three 1m× The 0.15m rock wool 4 is placed on the conveyor belt Ⅱ3, 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 initial bonding of the rock wool 4 and the acrylic veneer. In the second proc...

Embodiment 3

[0044] The polyurethane-modified rock wool thermal insulation decorative board of this embodiment is different from embodiment 1 in that the decorative surface material 6 is made of flexible stone, and the thickness of rock wool 4 is 10 cm. The specific operation steps of the production process are as follows:

[0045] Set the linkage speed of the conveyor belt Ⅱ3, conveyor belt Ⅰ16, double-track laminating mechanism, and coil unwinding mechanism 9 to 10m / min, and place the 0.9m×0.73m flexible stone on the conveyor belt Ⅰ16, 0.75m×0.6 The rock wool 4 of m is placed on the conveyor Ⅱ3, 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 ℃ is evenly poured on the rock wool 4 On the ...
