Biomass porous concrete sound absorption material and preparation method thereof
The invention relates to a biomass porous concrete sound absorption material which comprises the following raw materials in parts by mass: 60-65 parts of mud, 30-35 parts of water, 0.1-0.2 part of a foaming agent, 0.6-2 parts of an anti-cracking enhancer, 0.01-0.02 part of a flatting agent and 1-5 parts of a biomass material, and the foaming agent comprises lauryl sodium sulfate, sodium olefin sulfonate and an animal protein foaming agent in a mass ratio of 5: (1-2): 3. The surface of the biomass material is activated by ammonium dihydrogen phosphate. The biomass porous concrete sound absorption material provided by the invention has the characteristics of low price, environmental protection, light weight, sound absorption, non-combustibility, simple process and the like, and can be used for sound barrier materials and wall sound insulation layers on traffic such as expressways, railways, subways and the like.
本发明涉及一种生物质多孔混凝土吸声材料，按质量份数计，原料包括泥：60~65份，水：30‑35份，发泡剂：0.1‑0.2份，抗裂增强剂：0.6~2份，流平剂：0.01~0.02份，生物质材料：1‑5份，所述发泡剂为质量比为5：（1‑2）：3的十二烷基硫酸钠、烯烃磺酸钠、动物蛋白发泡剂，所述生物质材料采用磷酸二氢胺对生物质材料表面进行活化处理。本发明提供的生物质多孔混凝土吸声材料，具有价廉、环保、轻质、吸声、不燃工艺简单等特性，可用于高速公路、铁路、地铁等交通上的声屏障材料、墙体隔声层。
