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.
本发明公开了一种汽车地毯结构,包括由上至下的毯面层、胶膜或胶粉层和毛毡层,毯面层包括表皮层、附膜层和基底层,表皮层包括85%PET和15%LPET,面密度为200~450g/m2;附膜层包括PE膜,面密度为70~120g/m2;基底层包括85%PET和15%LPET,面密度为300~600g/m2;毯面层的厚度为3~6mm,胶膜或胶粉层包括PE膜或胶粉,面密度为70~120g/m2,毛毡层包括等密度PET毡,面密度为600~2000g/m2,厚度为3~25mm。上述汽车地毯结构通过改善地毯层结构,在保证吸隔音性能的同时,减轻地毯重量,且调整地毯各区域重质层的密度、使用范围,减少重质层的用量,同时减少地毯整体VOC排放。本发明还针对该地毯结构公开了具体的排布方式。
