The invention relates to the technical field of wall materials, and particularly discloses a sound-absorbing, noise-reducing and formaldehyde-removing wall material, a sound-absorbing, noise-reducing and formaldehyde-removing wall and a preparation method. The sound-absorbing, noise-reducing and formaldehyde-removing wall material comprises sound-absorbing layer slurry and sound-insulating layer slurry. The activated modified diatomite improves the porosity in the diatomite, improves the noise reduction and absorption effects of the sound absorption layer, and can assist in adsorbing harmful gases; the viscose fibers and the cotton fibers can form an interwoven structure, a porous structure is introduced into the sound absorption layer, formaldehyde is adsorbed, benzylidene-2, 4-pentanedione and formaldehyde can react conveniently, and the mechanical property of the sound absorption layer can be enhanced. The reaction mechanism of benzylidene-2, 4-pentanedione and formaldehyde is totally different from that of a monomer with an amino functional group in the prior art, the efficiency is higher, the reaction product can be subjected to cross-linking reaction, the cross-linking degree and compactness of the wall material are improved, the mechanical strength, water resistance and stain resistance of the wall material are improved, and the practical value and popularization value are higher.
本发明涉及墙体材料技术领域，具体公开一种吸音降噪除甲醛墙体材料、吸音降噪除甲醛墙体及制备方法。吸音降噪除甲醛墙体材料包括吸音层浆料和隔音层浆料。活化改性硅藻土提高了硅藻土内部的孔隙率，提升了吸音层的降噪吸收效果，并能辅助吸附有害气体；粘胶纤维和棉纤维可形成交织结构，在吸音层中引入多孔结构，对甲醛进行吸附，便于苯亚甲基‑2,4‑戊二酮与甲醛进行反应，还有利于增强吸音层的力学性能；苯亚甲基‑2,4‑戊二酮与甲醛反应的机理与现有技术中带氨基官能团的单体截然不同，且效率更高，该反应的产物还能进行交联反应，提高墙体材料的交联度和致密性，增加其机械强度、耐水性和耐沾污能力，具有较高的实用价值和推广价值。
