Abstract

The invention relates to a carpet for an automobile. The carpet for the automobile comprises a soft sound-insulating polyurethane layer (PUR), a hot melt adhesive layer and a surface protection layerwhich are sequentially arranged from bottom to top. The hot melt adhesive layer is made of an ethylene-vinyl acetate copolymer (EVA) or ethylene propylene diene monomer (EPDM), and the gram weight ofthe hot melt adhesive layer is 2880-3520 g / m<2>; and the surface protection layer is made of thermoplastic polyolefin (TPO), and the gram weight of the surface protection layer is 450-550 g / m<2>. Compared with the prior art, the carpet for the automobile provided by the invention has the advantages of convenience in cleaning, better appearance, good wear resistance, good sound insulation effect and the like.

Description

technical field [0001] The invention relates to the technical field of carpets, in particular to a carpet for automobiles and a manufacturing method thereof. Background technique [0002] With the rapid development of the automobile market and the continuous improvement of people's living standards, people's requirements for the sense of speed, driving, comfort, and safety of automobiles are also gradually increasing. At present, the car carpet is made of PET fiber carpet surface, and the back is foamed, or sound-absorbing materials such as formed felt are used. For example, Chinese patent CN 209240616U discloses a car carpet. The car carpet comprises: a fiber carpet surface, a first PE film layer, a high-strength felt, an ethylene-vinyl acetate copolymer layer, a second PE film layer and a sound-absorbing felt arranged in sequence from top to bottom, the fiber carpet surface and the The first PE film layers are bonded by a sizing glue. This patented technology uses the f...
