Problems solved by technology

The external wall thermal insulation cement decorative board has good fire resistance, heat preservation, durability, aesthetics and energy saving properties. However, the decorative layer of the existing external wall thermal insulation cement decorative board usually uses some flexible texture decorative materials, resulting in the external wall thermal insulation cement. The strength of the decorative board needs to be improved, and the durability is also defective

Abstract

The invention relates to the technical field of decorative boards, in particular to an outer wall heat insulation cement decorative board. The outer wall heat insulation cement decorative board comprises a light steel keep layer, wherein the upper surface and the lower surface of the light steel keep layer are respectively provided with an upper fiber reinforced cement board layer and a lower fiber reinforced cement board, the outer surface of the upper fiber reinforced cement board layer and the outer surface of the lower fiber reinforced cement board layer are respectively provided with an upper rock wool heat insulation layer and a lower rock wool heat insulation layer, and the outer surface of the upper rock wool heat insulation layer and the outer surface of the lower rock wool heat insulation layer are respectively provided with an upper polyurethane plate and a lower polyurethane plate. According to the outer wall heat insulation cement decorative board, the upper rock wool heatinsulation layer, the lower rock wool heat insulation layer, the upper polyurethane plate and the lower polyurethane plate are designed, the upper rock wool heat insulation layer and the upper polyurethane plate serve as an integral structure, and the lower rock wool heat insulation layer and the lower polyurethane plate serve as an integral structure, so that good heat insulation performance isachieved; and meanwhile, the heat conduction coefficient lambda is 0.043Wm<2>K, and a remarkable reduction effect is achieved on noise transmission, so that the heat and sound insulation effect of theouter wall heat insulation cement decorative board is improved.

Description

technical field [0001] The invention relates to the technical field of decorative panels, in particular to an exterior wall thermal insulation cement decorative panel. Background technique [0002] Modern Brief Introduction In addition to the more traditional glass, ceramics, stone and metal plates, there are many new architectural decoration materials with obvious characteristics when decorating the outer walls. Not only can it meet the characteristics of architectural decoration, but also can meet the better surrounding environment. The external wall thermal insulation cement decorative board has good fire resistance, heat preservation, durability, aesthetics and energy saving properties. However, the decorative layer of the existing external wall thermal insulation cement decorative board usually uses some flexible texture decorative materials, resulting in the external wall thermal insulation cement. The strength of the decorative board needs to be improved, and the dur...
