ても存在している。When the above-mentioned interior material based on paper-based cardboard is molded with a heating mold, it is difficult to deform in response to the shape of the mold, and there is a problem that wrinkles and tears are likely to occur. In particular, the problem that there is a large difference in the elongation in the extending direction of the corrugated form from the perpendicular direction and the elongation during molding, and the elongation in the extending direction of the corrugated form is low, which tends to cause defects such as tearing and wrinkles during molding, has been improved. It also exists for things that have been done.
本発明は上記欠点のない内装材を開発することである。 The object of the present invention is to develop an interior material that does not have the above-mentioned drawbacks.
即ち本発明は紙製の多数の小凸部を有する中た。That is, the present invention provides a medium having a large number of small convex portions made of paper.

る。In order to use it as an interior material, a skin material is fixed to the entire surface of the first liner. As for the skin material, a limited number of materials can be used (i.e., woven fabrics, non-woven fabrics, vinyl chloride sheets, elastomer sheets, etc.) that are currently used, or they can be laminated with a cushioning material such as urethane foam and attached to the liner in one layer. be done.

ンスをとるようにしている。In the above configuration, a space is formed by the paper core, and together with a synthetic resin liner welded to the core, the paper core functions as a base material to provide light weight and rigidity. The middle core should form many small convex parts! We try to balance the elongation in the direction and the ease of elongation.

。[Example 1] 4009An! Polypropylene resin of 300 Mrf is extruded and melt-coated on both sides of the core, which has many small convex portions, while one side is coated with 300 Mrf polypropylene resin. The interior material was prepared by welding and laminating the skin material made of the polyester nonwoven fabric of j~.

皮材をライナー面に溶着した。[Example 2] A base material was prepared by extruding and melt-coating each 3001/ypt" polypropylene on both sides of the core of Example 1. This base material was heated from both sides in a heating furnace, and immediately the material was coated with a hot-melt surface. The skin material was spread onto the surface of the molded product, and at the same time as compression molding, preheating was used to weld the skin material to the liner surface.
成形物について実施例1の熱サイクルテストを行った。The molded product was subjected to the thermal cycle test of Example 1.

をつくることができた。Structure of interior material [Effects of the invention] The present invention uses a paper core with many small convex portions, so elongation in the warp direction and ease of stretching are improved compared to conventional corrugated cores. By using a synthetic resin, the liner can be easily stretched during molding, and both of these make it easier to mold according to the shape of the mold, making molded automobile interior materials virtually free of tears and wrinkles that often occur during molding. I was able to make it.
