Embodiment Construction
[0014] Such as figure 1 As shown, the high-efficiency heat-insulating color steel composite panel of the present invention uses color steel plate or color aluminum plate as the substrate, and its technical scheme is: a non-woven fabric layer 2, an aluminum foil layer 5 and a PET composite layer are sequentially bonded on the outer surface of the substrate 1. The film layer 6 has embossing on the outermost PET film layer. The embossing on the PET lamination layer is concave-convex.
[0015] There are also PE coating and PE film layers between the non-woven fabric layer and the aluminum foil layer to make the layers of this product more firmly bonded. The test proves that this structure is not easy to peel off and delaminate even in the extremely low temperature cold zone; And enhance the noise reduction and heat insulation effect.
[0016] The high-efficiency heat-insulating color-steel composite board of the present invention has remarkable effects of heat insulation, sound ...
