The invention relates to a method for producing an automotive sound-absorption and heat-insulation integrated carpet and belongs to the technical field of automotive interior decorations. In the method, an environmentally-friendly 3.5
millimeter (including 0.8 millimeters of a
toughening layer, 2.5 millimeters of a foaming layer and 0.2
millimeter of a bottom film protective layer) PVC foamed leather is mainly used and subjected to heating, baking,
vacuum forming, cooling forming, 8
millimeter cotton-based sound-absorption and heat-insulation carpet compression and lamination, shearing,
hole making,
punching and inspection to produce a finished product. The method solves and improves the indexes, such as sound absorption, heat insulation, dust prevention, attractive appearance and easy cleaning, of the automotive carpet and makes the automotive carpet reach international advanced level-III and meet the design requirements on
environmental protection, attractive appearance, comfortableness, sound absorption and heat insulation of an automotive cab. In a plastic absorption process, a pneumatic pre-feeding device is used to ensure the thickness of the foamed leather on the highly-stretched part of the large section of the product, so the overall quality of the product is improved, the quality consistency of the product is guaranteed, the production efficiency is improved greatly and the labor intensity is relieved greatly. The compression and lamination of the sound-absorption and heat-insulation carpet improve the sound and heat insulation performance of the product and make the appearance of the product smooth and elegant and touch comfortable. In the while production process of the product, no harmful matter is produced, and the product is an environmentally-friendly product.
