The invention discloses an automobile sound insulation pad and a manufacturing process thereof, and relates to the technical field of automobile sound insulation. The automobile sound insulation pad comprises an aluminum foil, the bottom of the aluminum foil is fixedly connected with a vibration stopping plate, the bottom of the vibration stopping plate is fixedly connected with sound insulation cotton, the bottom of the sound insulation cotton is fixedly connected with film paper, the two sides of the sound insulation cotton are fixedly connected with glue, and the sound insulation cotton is fixedly connected with the film paper and the vibration stopping plate respectively. By adding the polyester fiber cotton, after production of the sound insulation pad is completed, the polypropylene fiber cotton is high in strength and good in elasticity, breakage is reduced, meanwhile, the polypropylene fiber cotton is overall fiber, the amount of fibrous dust is small, therefore the amount of sucked fibrous dust can be effectively reduced, the sound insulation pad can avoid stimulating the respiratory tract to induce diseases and reduce health hazards. Meanwhile, the polypropylene fiber cotton is large in fiber gap after being processed, so that the sound insulation effect is good.
本发明公开了一种汽车隔音垫及其制造工艺,涉及汽车隔音技术领域。一种汽车隔音垫及其制造工艺,包括铝箔,所述铝箔底部固定连接有止震板,所述止震板底部固定连接有隔音棉,所述隔音棉底部固定连接有膜纸,所述隔音棉2两侧均固定连接有胶水,且隔音棉分别和膜纸、止震板固定连接。本发明通过聚酯纤维棉的添加,能够使得隔音垫在生产完成后,进而使得聚丙烯纤维棉的强度高弹性好,减少了断裂,同时聚丙烯纤维棉为整体纤维,纤维状粉尘数量少,从而能够有效的减少纤维状粉尘吸入的数量,避免刺激呼吸道诱发疾病和减少对健康的危害,同时聚丙烯纤维棉经过加工后纤维间隙较大,进而隔音效果好。
