Abstract

The invention provides a novel interior decorating material for an automobile and a modification method thereof. The interior decorating material for the automobile comprises an epidermal layer, a foaming layer, a hot melt adhesive layer and a skeleton material which are sequentially stacked. The modification method comprises the following steps: (1) coating a surface of the skeleton material witha modifier, and forming a modified coating after curing, wherein the modifier comprises organic sulfonate, hydroxied acrylate and maleic anhydride grafted polypropylene; (2) subjecting the skeleton material coated with the modified coating to surface treatment with a supersonic flame to obtain a modified skeleton material; (3) subjecting the modified skeleton material to hydrothermal treatment; (4) thermally adhering the epidermal layer, the foaming layer and the hot melt adhesive layer simultaneously, and then compounding the layers after the thermal lamination with the modified skeleton material after the hydrothermal treatment together by vacuum forming. With the adoption of the modification method provided by the invention, the surface tension of the skeleton material of the interiordecorating material for the automobile is improved, the binding fastness between the skeleton material and the foaming layer is enhanced, and the impact resistance of the interior decorating materialfor the automobile is improved.

Description

technical field [0001] The invention belongs to the technical field of processing automobile interior parts, and in particular relates to a novel automobile interior material and a modification method thereof. Background technique [0002] The instrument panel is an important part of the car interior. In recent years, with the continuous advancement of technology, more operating functions have been concentrated into the instrument panel. Obviously, in order to ensure that the various instruments and parts supported can work normally under high-speed driving and vibration conditions, the instrument panel must have sufficient rigidity and impact resistance. [0003] Polypropylene (PP) is widely used as the skeleton material of automobile instrument panels because of its good processability, chemical resistance, light weight and low price. In the modern automobile industry, in order to increase the safety and comfort of passengers, many automobile dashboards are soft dashboard...
