Problems solved by technology

Due to the use of combustible polyurethane materials, the polyurethane edge-sealed rock wool composite board has insufficient fire resistance; and the steel-belt edge-sealed rock wool composite board has a large gap between the boards after installation, and the thermal insulation effect is poor.
At present, bare rock wool boards are mostly used as insulation materials for building curtain walls in the market. Rock wool is made of fiber materials. Because the fibers are afraid of water and moisture, ordinary rock wool boards do not have the effect of moisture and mildew resistance when used. In addition, the tensile strength of ordinary low-density rock wool on the market is very low, which cannot meet the strength requirements of the project. The strength of high-density rock wool is high, although it can meet the strength requirements of the project, but the manufacturing cost is high, and the sound-absorbing effect is significantly weakened

Abstract

The invention discloses a flame-retardant and sound-absorbing rock wool composite board, which is characterized in that a protective layer is attached to the upper surface of the rock wool, a grid frame is bonded to the lower surface, and a waterproof layer is covered on the upper surface of the protective layer. The grid runs through the rock wool and the protective layer, and is connected with the waterproof layer. The thickness of the rock wool is 60-150mm, and the surface bonded with the protective layer is provided with several holes that do not penetrate the rock wool. The protective layer is used for Glass fiber, with a thickness of 2-5mm, several straight grooves are dug on the protective layer, and the waterproof layer is polymer waterproof mortar, with a thickness of 10-20mm. The composite board not only has excellent heat insulation and flame retardant effect, but also has good sound absorption effect. At the same time, the straight grooves and hole grooves designed in the composite board can significantly improve the sound absorption effect of the composite board. The grid frame is inserted into the rock wool And the protective layer can effectively improve its tensile strength and indirectly prolong its service life.

Description

technical field [0001] The invention relates to a composite material for construction, in particular to a flame-retardant and sound-absorbing rock wool composite board. Background technique [0002] Existing rock wool composite panels include polyurethane edge-sealed rock wool composite panels and steel belt edge-sealed rock wool composite panels. Due to the use of combustible polyurethane materials, the polyurethane edge-sealed rock wool composite board has insufficient fire resistance; and the steel-striped edge-sealed rock wool composite board has large gaps between the boards after installation, and the thermal insulation effect is poor. At present, bare rock wool boards are mostly used as insulation materials for building curtain walls in the market. Rock wool is made of fiber materials. Because the fibers are afraid of water and moisture, ordinary rock wool boards do not have the effect of moisture and mildew resistance when used. In addition, the tensile strength of ...
