Technical Field

[0001] This utility model relates to the field of building materials technology, specifically to a sound insulation and heat preservation board with flame-retardant effect. Background Technology

[0002] Sound insulation and heat insulation board is a composite building material that combines sound insulation and heat insulation functions. It is mainly used to reduce noise transmission and reduce heat loss, and is widely used in construction, industrial equipment and other fields.

[0003] Existing sound insulation and heat insulation boards typically use high-density materials such as galvanized iron sheets, aluminum sheets, and stainless steel sheets as the outer layer, and are filled with sound insulation cotton and heat insulation materials to achieve sound insulation and heat insulation effects. Since rock wool boards are artificial inorganic fibers processed by high-temperature melting, they have the characteristics of being lightweight, having a low thermal conductivity, absorbing heat, and being non-combustible. In some existing technical solutions, rock wool is used as the sound insulation cotton filling material, which can achieve good flame retardant effects.

[0004] However, most existing sound insulation boards still have certain defects. For example, existing sound insulation boards with flame-retardant properties are often made by splicing multiple boards together when filling them with rock wool boards or other flame-retardant materials. Because there are long strip gaps between the boards, when a fire occurs, the fire can easily spread through the gaps between the boards, thus causing certain defects in use. Therefore, we propose a sound insulation board with flame-retardant properties to solve the problems mentioned above. Utility Model Content
