Polyester fiber carbon neutralization acoustic board and preparation method thereof
The invention relates to the field of sound-absorbing materials, and particularly discloses a polyester fiber carbon neutralization sound-absorbing board and a preparation method thereof. The polyester fiber carbon neutralization acoustical board comprises a polyester fiber acoustical board base body, wherein the polyester fiber acoustical board base body comprises the following substances in parts by weight: 75-100 parts of polyester fiber; 10 to 20 parts of a nano carbon material; the nano carbon material comprises acetylene black, a carbon nano tube and graphene oxide, and the mass ratio of acetylene black to carbon nano tube to graphene oxide is 1: 3-4: 8. The preparation method comprises the following steps: S1, immobilizing the microbial inoculum; s2, preparing the polyester fiber acoustic board; s2, preparing a mesoporous graphene gel solution; and S3, coating and compounding. The polyester fibers and the nano carbon material are compounded, sound waves shuttle among tiny holes and bubbles, friction is generated between the sound waves and hole walls due to vibration of the sound waves, and finally part of sound energy is converted into heat energy to be consumed, so that the sound absorption effect is effectively improved.
本申请涉及吸音材料的领域，具体公开了一种聚酯纤维碳中和吸音板及其制备方法。一种聚酯纤维碳中和吸音板包括聚酯纤维吸音板基体，所述聚酯纤维吸音板基体包括以下重量份物质：聚酯纤维75～100份；纳米碳材料10～20份；所述纳米碳材料包括按乙炔黑、碳纳米管和氧化石墨烯，所述乙炔黑、碳纳米管和氧化石墨烯的质量比为1:3～4:8。其制备方法为：S1、菌剂固定化；S2、聚酯纤维吸音板制备；S2、介孔石墨烯凝胶液制备；S3、涂覆复合。本申请通过采用聚酯纤维与纳米碳材料进行复合，声波在微小空洞和气泡间穿梭，声波的振动使之与孔壁之间产生摩擦，最终导致部分声能转化为热能消耗掉，从而有效改善其吸音效果。
