摘　　要：采用轧-烘-焙工艺,用聚甲基丙烯酸酯成膜剂和含氟防水剂处理涤纶织物,制备具有防水性能的手机听筒膜。采用混响室—消声室法、耐水压测试仪和水接触角仪分别测定织物的隔声量、耐水压和水接触角,场发射扫描电镜观察微观形貌。结果表明:随着织物孔径减小,其隔声性能增强;随着成膜剂和防水剂浓度的增加,织物耐水压增大,但隔声量也增加。当成膜剂体积分数为30%,防水剂体积分数为10%,焙烘温度为180℃,焙烘时间为300s时,可得到耐水压为3 000Pa,在0～20 000Hz频率范围内隔声量小于3dB的手机听筒膜材料。Polymethacrylate membrane-forming agent and fluoric water-proofing agent are used to process polyester fabrics and earphone membrane of mobile phone with waterproof property is prepared through rolling-roasting process. This paper measures the sound insulation, hydraulic pressure resistance and water contact angle of fabrics respectively using reverberation room-dead room method, hydraulic pressure resistance tester and water contact angle meter and observes microstructure through field emission scanning electron microscopy. The result shows that the acoustic insulation property of fabrics improves with the decrease of its aperture and that the hydraulic pressure resistance and sound insulation increase with the increase of concentration of membrane-forming agent and water-proofing agent. When the volume fraction of membrane-forming agent is 30%, the volume fraction of water-proofing agent is 10%, roasting temperature is 180℃ and roasting time is 300 s, earphone membrane material with hydraulic pressure resistance 3 000 Pa and sound insulation〈3 dB within the frequency range 0-20 000 Hz.
