Abstract

The invention discloses an automobile carpet structure which comprises a carpet surface layer, a glue film or glue powder layer and a felt layer from top to bottom. The carpet surface layer comprisesa surface layer, a film attaching layer and a base layer, the surface layer comprises 85% of PET and 15% of LPET, and the surface density is 200 to 450 g / m<2>; the film attaching layer comprises a PEfilm, and the surface density is 70 to 120 g / m<2>; the substrate layer comprises 85% of PET and 15% of LPET, and the surface density is 300 to 600 g / m<2>; the thickness of the carpet surface layer is3 to 6mm, the glue film or glue powder layer comprises a PE film or adhesive powder, the surface density is 70 to 120g / m<2>; the felt layer comprises an equal-density PET felt, the surface density is600 to 2000g / m<2>, and the thickness is 3 to 25mm. According to the automobile carpet structure, by improving the carpet layer structure, the weight of the carpet is reduced while the sound absorptionand insulation performance is guaranteed, the density and the use range of heavy layers in all areas of the carpet are adjusted, the use amount of the heavy layers is reduced, and meanwhile VOC emission of the whole carpet is reduced. The invention further discloses a specific arrangement mode for the carpet structure.

Description

technical field [0001] The invention relates to the technical field of automotive interior parts, in particular to a car carpet structure and arrangement. Background technique [0002] Car passenger compartment carpets are generally installed on the body floor sheet metal, and have the functions of exterior decoration and absorption and isolation of outside noise. The traditional carpet is generally composed of a carpet surface, a heavy layer and a sound-absorbing layer. In order to ensure the sound absorption and sound insulation effect, the heavy layer is generally set to be a heavy material with the same surface density as the carpet surface, and the density is generally 1 to 5. (kg / m 2 ), and the sound-absorbing layer is equal density PET felt or PU foam material. Although this structure has good sound absorption and sound insulation performance, it will lead to the overall weight of the carpet, which is difficult for workers to install, and the cost is high. At the sa...
