Rock wool heat-preserving and decorating board

The utility model discloses a rock wool heat-preserving and decorating board. The rock wool heat-preserving and decorating board comprises two cement fiber substrates which are arranged in parallel, wherein a rock wool layer is fixed between the two cement fiber substrates, a plurality of through holes are formed in the lower cement fiber substrate, and the upper surface of the upper cement fiber substrate is coated with a UV fluorocarbon layer. The cement fiber substrates are adopted, and thus the rock wool heat-preserving and decorating board is resistant to water and fire, capable of insulating sound and heat, light in weight and high in strength. Meanwhile, due to the fact that the through holes are formed in the lower cement fiber substrate, the function that the extending direction of rock wool fibers of the rock wool layer between the upper cement fiber substrate and the lower cement fiber substrate is basically perpendicular to the cement fiber substrates is ensured, thus, the compression resistance a
