The Sound Adsorption of Poly Vinyl Chloride Nanocomposites, Consisting of Silica, Zinc oxide, Zeolite A to Noise Pollution Control
Abstract
The first aim of this study was to synthesize poly vinyl chloride (PVC) nanocomposites, consisting of various additive nanoparticles, including Silica, Zinc oxide (ZnO), and Zeolite A nanoparticles. The size of Silica, ZnO, and Zeolite A nanoparticles were near 30±2, 45±5, and 100±5 nm, respectively. The second aim was to investigate the effect of these nanoparticles on sound absorption, density, heat change, expansion, and contraction. This study was an experimental one . In this study, three nanoparticles were used, including Silica, ZnO, and Zeolite A. This study showed that PVC/Silica: 0.51%, PVC/Silica: 0.29%, PVC/Zeolite A: 6.1%, and PVC/Silica: 0.51% had the highest sound adsorption coefficient at frequency of 250, 500, 1000, and 2000 Hz, respectively. Moreover, the increase of Zeolite A and ZnO nanoparticles led to increase of density. In case of Silica nanoparticles, the increase of content of nanoparticles led to decrease of density. The heat change experiment showed that the increase of Zeolite A led to decrease of heat change, but the increase of Silica led to increase of heat change. It was found that PVC/Silica: 0.51% had minimum contraction and expansion. Taken together, PVC/Silica: 0.51%, PVC/Silica: 0.29%, PVC/Zeolite A: 6.1%, and PVC/Silica: 0.51% nanocomposite had highest sound adsorption coefficient at frequency of 250, 500, 1000, and 2000 Hz, respectively.
