Description

Technical Field

[0001] This utility model relates to the field of rock wool technology, and in particular to a rock wool composite board. Background Technology

[0002] Rock wool composite panels are multifunctional building insulation materials made by combining rock wool as the core material with other materials through a composite process. They have fireproof, heat insulation, and sound insulation properties and are widely used in construction, shipbuilding, and industrial equipment. Rock wool composite panels have a certain heat insulation capacity under normal operating temperatures, but their heat insulation coefficient drops significantly above their characteristic temperature. They are prone to structural failure at high temperatures and may not be able to effectively block flames, thus reducing their overall fire resistance and heat insulation performance. Although traditional rock wool composite panels are lighter than traditional building materials, their weight is still relatively high (usually around 2000-2500 kg / m³), making it difficult to meet the modern building requirements for lighter structures. Utility Model Content

[0018] The aluminum-zinc coated steel surface layer 104 has raised guide lines 1041 pressed into its surface. The surface of the aluminum-zinc coated steel surface layer 104 is coated with a hydrophobic coating to improve corrosion resistance and prevent water penetration. The bottom surface of the inner substrate 105 has a pre-set dry-hanging groove, and the lower surface of the inner substrate 105 is covered with a PVC film, which serves both as a moisture-proof and decorative surface.
