Problems solved by technology

[0003] Chinese patent document CN201484319U discloses a car headliner trim panel, which comprises a fabric layer, a composite layer and a bottom layer from top to bottom, and the upper and lower sides of the composite layer are respectively attached with An upper glued film and a lower glued film, the fabric layer is bonded to the upper glued film of the composite layer, and the bottom layer is bonded to the lower glued film of the composite layer, wherein the glued film is polyethylene, and the The composite layer is made of hemp fiber base material. Although this composite material solves the problem of poor toughness and impact resistance of PU board, its sound insulation and heat insulation effect is not good, and its air permeability is not good.
The sound-insulation, heat-insulation and fire-proof board for the car roof disclosed in this document, although the polyethylene foaming in the middle layer forms holes, which can partially play the effect of ventilation, but it is affected by the foaming process, and in the case of uneven foaming At the same time, because the board is foamed with polyethylene, its strength is not good. Although the strength can be improved by adding the hemp fiber layer, the air permeability will become poor after the hemp fiber layer is combined.

Abstract

The invention relates to the field of interior trim of an automobile, in particular to air-permeable interior trim composite board material for the ceiling of an automobile. The composite board material comprises an intermediate foam layer, and the upper surface and the lower surface of the intermediate foam layer are laminated with an upper surface layer and a lower surface layer both having a via-hole, respectively. With such configuration, the composite board material has better sound insulation and heat insulation effects compared with intermediate foam layer-containing board material in the prior art.

Description

technical field [0001] The invention relates to the field of interior decoration of automobiles, in particular to a composite panel for interior decoration of automobile ceilings. Background technique [0002] With the rapid development of the automotive industry, automotive interior materials are gradually introducing new ones in the direction of green and environmental protection. Traditional automotive interior parts usually use PU board (polyurethane board) or PP (polypropylene) wood powder board, which has the advantages of good formability and high tensile strength, but its air permeability and toughness are poor, and it is not impact resistant. . [0003] Chinese patent document CN201484319U discloses a car headliner trim panel, which comprises a fabric layer, a composite layer and a bottom layer from top to bottom, and the upper and lower sides of the composite layer are respectively attached with An upper glued film and a lower glued film, the fabric layer is bond...
