Polyester fiber acoustic absorption body capable of adsorbing hazardous substances and preparation method thereof
The invention discloses a polyester fiber acoustic absorption body capable of adsorbing hazardous substances and a preparation method thereof. The polyester fiber acoustic absorption body is composedof low-melting-point polyester short fibers, conventional type polyester short fibers, carbon particles, kieselguhr, graphene, charcoal and reinforcing adsorption components. The preparation method ofthe polyester fiber acoustic absorption body comprises the steps of conducting weighing, opening, mixing and carding on the fibers, so that a fiber net is formed; uniformly mixing the carbon particles, the kieselguhr, the graphene and the charcoal into the fiber net; conducting piling and needling on the fiber net; after needling, putting cotton felt on fiber cotton, and then, conducting needlingof the second time, so that needled cotton felt is formed; cutting the needled cotton felt into needled cotton felt pieces, and conducting heat setting; and conducting mold extrusion, so that the needled polyester fiber acoustic absorption body can be obtained. After the acoustic absorption body is attached to a wall, a cavity can be formed between the acoustic absorption body and the wall; no keel is needed, and acoustic vibration transmission is reduced; the better effect of noise reduction by absorption is achieved; and adhesive is not used, and the carbon particles can effectively adsorbthe hazardous substances.
本发明公开了一种能够吸附有害物质的聚酯纤维吸音体及其制备方法，聚酯纤维吸音体由低熔点聚酯短纤维、常规型聚酯短纤维、炭颗粒、硅藻土、石墨烯、生物炭和加强吸附组分组成。聚酯纤维吸音体的制备方法包括将纤维进行称重、开松、混合、梳理形成纤维网，在纤维网内均匀混入炭颗粒、硅藻土、石墨烯和生物炭，将纤维网进行堆置和针刺，针刺后在纤维棉上放置棉毡，然后进行第二次针刺，形成针刺棉毡，针刺棉毡切割成针刺棉毡块并进行热定型，经模具挤压后即可制得针刺聚酯纤维吸音体。本发明中的吸音体贴于墙上后，可以与墙体形成空腔，省去了龙骨，减少了声音的振动传递，更好的起到吸声降噪效果，不使用胶粘剂，炭颗粒还可有效吸收有害物质。
