Preparation method of natural bamboo fiber reinforced silicon dioxide aerogel sound-absorbing material
The invention provides a preparation method of a natural bamboo fiber reinforced silicon dioxide aerogel sound-absorbing material, and belongs to the technical field of sound-absorbing materials. The preparation method comprises the following steps: S1, extracting natural bamboo fibers; s2, carrying out alkali treatment on the natural bamboo fibers and adding a silicon source; s3, acidizing the treating fluid; s4, preparing natural bamboo fiber wet gel through catalysis of alkali liquor; s5, wet gel solvent replacement, aging and hydrophobic modification; and S6, drying the wet gel to prepare the aerogel. The natural bamboo fiber reinforced silicon dioxide aerogel prepared by the preparation method disclosed by the invention has relatively high bending strength, strong deformation resistance and relatively large sound insulation index, and has a wide application prospect in the field of sound absorption materials.
本发明提出了一种竹原纤维增强二氧化硅气凝胶吸音材料的制备方法，属于吸音材料技术领域，包括以下步骤：S1.竹原纤维的提取；S2.竹原纤维碱处理及硅源添加；S3.处理液酸化处理；S4.碱液催化制备竹原纤维湿凝胶；S5.湿凝胶溶剂置换、老化及疏水改性；S6.湿凝胶干燥制成气凝胶。本发明制备的竹原纤维增强二氧化硅气凝胶具有较高的弯曲强度，抗变形能力强，隔声量较大，在吸音材料领域具有广阔的应用前景。
