Abstract

The search for green composite for sound-absorbing material has increased a significant interest. In this study, polystyrene (PS) composite foam filled with primary sludge and boiler ash from pulp mill was produced. The product was characterized using analytical techniques such as FTIR, XRD, SEM, TGA, and DSC, while the mechanical properties and sound-absorbing coefficient were analyzed regarding ASTM D 2240 and ASTM E-1050-98, respectively. The results showed that the sludge has 1β crystalline polymorph cellulose from the pulp. The chemical reaction can be seen by the chemical bond formed during the mixing process. The peak expansion occurred at 1600.44 cm-1 indicating the presence of a C=C functional group of maleic anhydride with polymer and filler. SEM images showed that the filler was distributed and dispersed into the polymer matrix and no agglomeration was produced. The sound-absorbing composites had complied ISO 11654:1997 regarding the sound absorption coefficient rating level on materials for rooms with sound absorption classes D and C with the value of α 0.328-0.793.

纸浆厂一次污泥和锅炉灰填充聚苯乙烯复合材料的声学和力学性能

寻找用于吸声材料的绿色复合材料引起了人们的极大兴趣。本研究以纸浆厂的一次污泥和锅炉灰为原料，制备了聚苯乙烯（PS）复合泡沫。使用FTIR、XRD、SEM、TGA和DSC等分析技术对产物进行表征，同时分别根据ASTM D 2240和ASTM E-1050-98分析机械性能和吸声系数。结果表明，污泥中含有1β晶型纤维素。化学反应可以通过混合过程中形成的化学键来观察。峰膨胀发生在1600.44cm-1处，表明马来酸酐与聚合物和填料存在C=C官能团。SEM图像显示，填料分布并分散在聚合物基体中，没有产生团聚。吸声复合材料符合ISO 11654-1997关于吸声等级为D和C的房间材料的吸声系数等级的规定，其值为α0.328-0.793。
