The invention discloses an automobile carpet sound insulation pad and an automobile. The sound insulation pad comprises a carpet surface layer, a carpet sound absorption and insulation layer and a carpet flame-retardant layer which can be assembled in a layered mode. The carpet surface layer comprises a needle-punched PET fiber and chinlon PA66 fiber composite fabric layer, the carpet sound absorption and insulation layer comprises a dual-density cotton felt layer, and the carpet flame-retardant layer comprises a thermoplastic polyolefin elastomer TPO composite EVA layer. The needle-punched PET fiber and chinlon PA66 fiber composite fabric layer is prepared by mixing PET fibers with the fiber diameter of 0.04-0.06 mm and 12-18% of chinlon PA66 fibers, the thickness of the needle-punched PET fiber and chinlon PA66 fiber composite fabric layer is 6-8 mm, and the material gram weight of the needle-punched PET fiber and chinlon PA66 fiber composite fabric layer is 450-560 g/m < 2 >. The carpet sound insulation pad has the dual functions of fatigue resistance, corrosion resistance, mildew resistance, sound absorption and sound insulation, and is low in cost, simple in process, easy to assemble and stable in flame retardant property, and the flame retardant safety coefficient can be greatly improved.

    本发明公开了一种汽车地毯隔音垫及汽车,所述隔音垫包括可分层装配的地毯表层、地毯吸隔声层和地毯阻燃层;所述地毯表层包括针刺PET纤维和锦纶PA66纤维复合面料层,所述地毯吸隔声层包括双密度棉毡层,所述地毯阻燃层包括热塑性聚烯烃弹性体TPO复合EVA层;所述针刺PET纤维和锦纶PA66纤维复合面料层由纤维直径0.04mm~0.06mm的PET纤维和12~18%的锦纶PA66纤维混合制备而成,厚度在6‑8mm,材料克重在450‑560g/m2。该地毯隔音垫具有耐疲劳性、耐腐蚀性能、抗霉变,以及吸声、隔声的双重作用,而且,成本低,工艺简单,易于装配,阻燃性能稳定,可大大提高阻燃安全系数。
