摘要
为解决能源开采过程中噪声污染对人类健康和生态环境造成的影响,开发一种适用于多场景、环保且高效的吸声材料.采用三聚氰胺和多聚甲醛为基材,结合多功能助剂,通过创新的循环鼓泡均化协同交联接枝技术和虹吸流控梯度微波一体化成形发泡技术,制备了一种轻质、疏水疏油、高吸声性能的蜜胺基材料.此外,通过开发蜂窝内嵌蜜胺泡沫,进一步优化了材料的吸声性能和应用范围.结果表明,该材料在500～2 500 Hz频率内,平均吸声系数达到0.85,显著优于传统多孔吸声材料的平均吸声系数0.65.改性材料在频率为500 Hz时的平均吸声系数分别提升至0.54和0.56.开发的新型蜜胺基材料不仅在星际空间、超低温、潮湿和重油污等恶劣环境下展现出卓越的吸声性能,而且在石油开采等能源开发领域具有广泛的应用潜力.此外,材料在大通风量隔声房中的应用显著提高了降噪效果,平均消声量达到37.1 dB,远超传统隔声房的24.7 dB.
Abstract
To address the impact of noise pollution on human health and the ecological environment during energy extraction,a versatile,environmentally friendly,and highly efficient sound-absorbing material was developed.Utilizing melamine and polyformaldehyde as the base materials,combined with multifunctional additives,an innovative cyclic bubble homogenization synergistic grafting technology and siphon flow-controlled gradient microwave integrated molding foaming technology were employed to fabricate a lightweight,hydrophobic,oleophobic,and highly sound-absorbing melamine-based material.Furthermore,the development of honeycomb-embedded melamine foam optimized the sound-absorbing performance and application range of the material.Results showed that this material achieved an av-erage sound-absorbing coefficient of 0.85 within the frequency range of 500-2 500 Hz,significantly outperforming the average coeffi-cient of 0.65 of traditional porous sound-absorbing materials.The average sound-absorbing coefficients of the modified materials at a fre-quency of 500 Hz were increased to 0.54 and 0.56 respectively.The newly developed melamine-based material not only demonstrated excellent sound-absorbing performance in harsh environments such as interstellar space,ultra-low temperatures,humidity,and heavy oil pollution but also holded broad application potential in the field of energy development like oil extraction.Additionally,the application of the material in large air volume sound insulation rooms significantly improved noise reduction effects,with an average sound reduction of 37.1 dB,far exceeding the 24.7dB of traditional sound insulation rooms.
