Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] Such as figure 1 As shown, the high-sound insulation vehicle carpet made of PVC is made of five layers of materials and has a five-layer structure. From the surface layer to the bottom layer, there are an upper anti-skid layer 11, an upper sound insulation layer 21, and a foam layer 31. , the lower sound insulation layer 22 and the lower anti-slip layer 12; the materials of each layer are PVC materials, and the thickness, density and hardness of each layer of materials in each embodiment are specifically shown in Table 1 below. The upper anti-slip layer 11, the upper sound insulation layer 21, the foam layer 31, the lower sound insulation layer 22 and the lower anti-slip layer 12 are bonded by hot pressing to form a multi-layer constrained sheet, which is formed into a PVC material by heating and blistering. Carpets for high sound ins...

Abstract

The invention discloses a PVC (polyvinyl chloride) carpet for a high-sound-insulation vehicle and a preparation method thereof. The PVC carpet for the high-sound-insulation vehicle is prepared by processing five layers of materials in a combined way and is in a five-layer structure including an upper anti-skidding layer, an upper sound insulation layer, a foaming layer, a lower sound insulation layer and a lower anti-skidding layer in sequence from a surface layer to a bottom layer, and all the layers are made of PVC materials with excellent fire resistance and sound insulation performance. The thickness, the density and the rigidity of all of the layers are selected and determined in accordance with vehicle noise spectrum characteristics. All of the layers are bonded through hot pressing, so as to form a sheet in a multi-layer constraint structure, and then the carpet used for the vehicle is manufactured through thermoforming and used in a vehicle cab. The carpet manufactured by using the method has good sound insulation performance, the sound insulation performance of the carpet can be regulated by utilizing the thickness, the density and the rigidity of all of the layers, the cab noise is reduced, and the acoustical quality of the vehicle cab is increased.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a high-sound-insulation vehicle carpet made of PVC and a preparation method thereof. Background technique [0002] With the continuous innovation of vehicle manufacturing technology, drivers and passengers pay more attention to the problem of vehicle noise, because vehicle noise, especially the noise level of the cab, directly affects the comfort of the vehicle. Various noise reduction technologies and noise reduction material products are widely used in the field of vehicle manufacturing. [0003] The Chinese invention patent application with the application publication number CN 102218864 A discloses a kind of automotive interior parts, which are respectively bonded by polyester chemical fiber non-woven fabrics, EPDM and foamed PU, and have good sound insulation, heat insulation and Shock absorption function. The automotive interior parts provided by this invention are al...
