る。(Prior art) Japanese Patent Laid-Open No. 57-2722 discloses a highly decorative interior material for automobiles such as automobile door trims.
As seen in the above publications, the surface of a molded base material is usually covered with a laminated skin material in which a cushion layer made of synthetic resin foam is laminated to the skin, with an adhesive interposed between them. Automotive interior materials are usually produced by coating a pre-prepared molded base material with a laminated skin material by means such as vacuum forming.

In addition, molds and other equipment costs are high, making it difficult to mass-produce at a low cost.In addition, if the cushion layer of the laminated skin material is processed while being impregnated with adhesive during the coating process of the laminated skin material, air bubbles may occur in the cushion layer. There are various problems such as the adhesive being crushed and not providing a soft feel, and especially when a fibrous skin is used, the adhesive seeps into the skin and spoils the appearance.

るものである。(Means for Solving the Problems) The present invention has been completed with the aim of producing an automobile interior material that solves the above-mentioned problems. A laminated skin material made by laminating a cushion layer having pores and a film having a melting point higher than the melting temperature of the thermoplastic synthetic resin board is placed between a mold for deep drawing of the synthetic resin, with the film facing toward the thermoplastic synthetic resin board. A molding base made of the thermoplastic synthetic resin plate material, which has adhesive properties due to melting by setting the thermoplastic synthetic resin plate material in such a manner and press-molding it at a high temperature above the melting temperature of the thermoplastic synthetic resin plate material and below the melting temperature of the film. This method is characterized in that a laminated skin material is integrally coated on the surface of the material with a film on the back surface being adhered to the surface during melt molding of the molding base material.

Fabric or non-woven fabric that is soft to the touch and breathable should be used as the outer skin.In particular, if the molding base material has large irregularities, the outer skin will stretch and if the stitches are too far apart, the appearance will be impaired. Preferably. Furthermore, since the cushion layer having open cells needs to have excellent breathability as well as cushioning properties, a synthetic resin foam having numerous open cells is preferable. A polyurethane foam that has a heat-resistant temperature that does not melt during pressure molding is optimal. Next, the film only needs to have a melting point higher than that of the thermoplastic synthetic resin plate material, but synthetic resin films that have a high elongation and are easily adhered to the surface of the molding base material during melt molding, such as those with a heat resistant temperature. Polyamide hot melt film, etc., which is heated to 140°C or higher, is most suitable.

布しておいてもよい。(Example) Next, the present invention will be explained in detail with reference to illustrated process diagrams. Reference numerals 1 and 1 are a pair of molds for deep drawing of synthetic resin, and the molds 1 and 1 are shown in FIG. A stamping molding grade polypropylene resin sheet with a melting temperature of 140°C is set as the thermoplastic synthetic resin plate material 2 so as to face the male side of the molds 1, 1, and the space between the molds 1, 1 is A laminated skin material 4 is set facing the female mold side with its edges clamped by clamps 3, 3. The laminated skin material 4 includes a skin 5 made of fabric, a cushion layer 6 made of polyurethane foam having continuous pores and having excellent pressure resilience, and a film 7 with a melting temperature of 150°C and a wall thickness of 60 to 100 μm. Using a polyamide resin hot melt film laminated with a well-known lamination method,
The film 7 is set on the thermoplastic synthetic resin board 2 side. During molding, the thermoplastic synthetic resin plate material 2 is heated to 140°C and softened using a heating device such as an infrared heater.
By operating the ton press machine and pressing the molds 1 and 1 as shown in Fig. 2, the thermoplastic synthetic resin plate material 2 is molded into the desired shape by the molding equipment 20 at a high pressure of about 20 kg/cm 2 per unit area. At the same time as being deep-drawn, the laminated skin material 4 is bonded to the surface of the molded base material 20 which is still in a molten state, with the cushion layer 6 in a compressed state and the unmelted film 7 on the back surface thereof. . When the mold is opened, the compressed laminated skin material 4 itself has continuous pores, and the skin 5 is also fibrous and breathable, so air enters and gradually returns to its original thickness. When restored, a product 30 with a soft feel and excellent decorative properties is obtained as shown in FIG. In addition,
The surface of the thermoplastic synthetic resin board 2 may be coated with an adhesive in advance.

のである。(Effects of the Invention) As is clear from the above description, the present invention is capable of simultaneously covering the laminated skin material when molding a molding base material from a thermoplastic synthetic resin plate material, which not only simplifies the manufacturing process but also eliminates the need for molds and other materials. Equipment costs can be significantly reduced, and the film on the back side of the laminated skin material prevents adhesives and molten resin from migrating and impregnating the cushion layer and the skin during the coating process of the laminated skin material. Even if the cushion layer collapses during compression, the fibrous skin and breathability of the cushion layer allow the compressed cushion layer to properly return to its original shape when the pressure is released, resulting in a soft feel and excellent decorative properties. This method has various advantages such as the ability to obtain products, and it is a method for producing interior materials for automobiles that solves the problems of the conventional methods, contributing greatly to the development of the industry.
