The invention discloses an automotive trim covering part with environment-friendly and antibacterial effects, which comprises a framework and a fabric, a hot melt adhesive layer is arranged between the framework and the fabric, and the framework and the fabric are bonded by the hot melt adhesive layer. The material of the skeleton layer sequentially comprises a surface layer non-woven fabric, a surface layer glass fiber felt, a PUR plate, a back layer glass fiber felt and a back layer non-woven fabric from the surface layer to the back layer, and PU molding glue for bonding the PUR plate, the surface layer glass fiber felt, the surface layer non-woven fabric and the back layer non-woven fabric together, and the surface layer non-woven fabric is a surface layer anti-seepage glue non-woven fabric. The hot melt adhesive film is adopted to replace solvent adhesive and water-based adhesive to serve as a bonding material, introduction of a large number of small molecular substances is avoided, VOC and odor indexes of the ceiling are obviously improved, and compared with the solvent adhesive and the water-based adhesive, the hot melt adhesive film does not contain a solvent, is a high polymer material and does not contain the small molecular substances.

    本发明公开了一种具有环保抗菌效果的汽车内饰覆盖件,包括骨架和面料,所述骨架和面料之间设置有热熔胶粘层,所述热熔胶粘层将骨架和面料进行粘接,其中骨架层的材料从面层到背层依次包含面层无纺布、面层玻纤毡、PUR板、背层玻纤毡和背层无纺布,以及把PUR板、面层玻纤毡与面层无纺布和背层无纺布粘接在一起的PU成型胶,面层无纺布为面层防渗胶无纺布。本发明通过采用热熔胶膜替代溶剂胶和水性胶,作为粘接材料,避免引入大量的小分子物质,明显提高了顶棚的VOC和气味指标,相对于溶剂胶和水性胶而言,热熔胶膜不含有溶剂,为高分子材料,也不含有小分子物质。
