将具有吸音性能的蛭石粉作为填料,利用胶原纤维与植物纤维混合制备吸音纸,研究蛭石粉对吸音纸物理特性和吸音性能的影响,并分析纸页结构形态对吸音性能的影响。结果表明:蛭石粉的用量保持在15%左右,纸页性能变化较小;而且蛭石粉可以改善纸页的吸音性能,纸页结构更均匀,使其吸音性能稳定。
Using vermiculite with sound-absorbing properties as filler, the sound-absorbing paper was made by mixing collagen fibers and plant fibers to study the effect of vermiculite on the sound-absorbing paper’s physical properties and sound-absorbing properties. The paper also analyzed the influence of paper sheet structure on sound-absorbing performance. The results showed that the amount of vermiculite remained at about 15%, and the performance of paper was little changed. Moreover, vermiculite powder could improve the sound-absorbing performance of paper and the paper structure was more uniform, which made the sound-absorbing performance stable.
