The sound-insulation
flame-retardant carpet comprises a carpet body, flow guide grooves are dug in the upper
surface layer of the carpet body, protruding strips are arranged on the upper
surface layer of the carpet body, hook-and-loop fasteners and limiting
cushion columns are arranged on the bottom layer of the carpet body, and a first assembling piece and a second assembling piece are arranged at the left end and the right end of the carpet body respectively. A first waterproof layer is laid and bonded on the lower side of the upper
surface layer of the carpet body, a second waterproof layer is laid and bonded on the upper side of the bottom layer of the carpet body, a first
flame-retardant layer is laid and bonded on the lower side of the first waterproof layer, a second
flame-retardant layer is laid and bonded on the upper side of the second waterproof layer, a first supporting plate is laid and bonded on the lower side of the first flame-retardant layer, and a second supporting plate is laid and bonded on the upper layer of the second flame-retardant layer. A first silencing
fiber layer is laid and bonded on the lower side of the first supporting plate, a second silencing
fiber layer is laid and bonded on the upper side of the second supporting plate, and silencing cotton is laid and bonded between the first silencing
fiber layer and the second silencing
fiber layer; the carpet body can be limited and fixed in the vehicle, slipping is effectively avoided, deformation resistance, sound insulation and flame retardant effects are good, and user experience is improved.
