The invention relates to the technical field of vehicle sound insulation, in particular to a vehicle sound absorption and insulation pad, a manufacturing method and a vehicle. A vehicle sound absorption and insulation pad comprises a first sound absorption layer, a sound insulation layer and a second sound absorption layer, the first sound absorption layer and the second sound absorption layer are fixedly arranged on the two sides of the sound insulation layer respectively, and the sound insulation layer is a superfine fiber hard felt made of polyethylene glycol terephthalate superfine fibers. Wherein low-melting-point polyethylene glycol terephthalate is mixed in the polyethylene glycol terephthalate superfine fibers. The technical problems that an existing ABA type sound insulation pad is poor in smell and heavy in weight, and the sound absorption and insulation effect needs to be improved are solved.

    本申请涉及车辆隔音技术领域,具体涉及一种车辆吸音隔音垫、制造方法及车辆。一种车辆吸音隔音垫,包括第一吸音层,隔音层和第二吸音层,所述第一吸音层和所述第二吸音层分别固定设置在所述隔音层两侧,所述隔音层为由聚对苯二甲酸乙二醇酯超细纤维制成的超细纤维硬毡,其中所述聚对苯二甲酸乙二醇酯超细纤维中混合有低熔点聚对苯二甲酸乙二醇酯。解决了现有ABA型隔音垫气味不佳,重量较重,吸音隔音效果有待提高的技术问题。
