This invention belongs to the field of building materials technology, specifically disclosing a sound-absorbing porous foamed concrete composite board and its preparation method. Using foamed concrete as the substrate of the composite board effectively solves the problem of poor environmental performance of traditional sound insulation materials. Compared with materials such as polystyrene and sound-absorbing rock wool, it does not require a large amount of energy for preparation and can utilize recycled raw materials. It does not produce toxic powder after aging, reducing harm to the air environment and human health, while also avoiding the flammability hazards of traditional materials. The closed-cell sound insulation layer's sealed pores can block direct sound wave penetration, achieving basic sound insulation. The sound-absorbing pores of the porous sound-absorbing layer, combined with the interconnected channels, introduce incident sound waves into the interior. Energy is dissipated through reflection and friction within the channels, forming a dual protection of "sound absorption and sound insulation." This solves the core problem of poor sound insulation performance of traditional concrete and compensates for the short lifespan of traditional sound insulation materials, extending the overall service life of the board.
