する方法がある。Interior parts such as pillars and door trims use materials that are highly rigid, have flexibility on one side, and have textured surfaces. As one such material, a number of laminate molded bodies made by laminating high-rigidity materials and flexible materials have been tried. For example, a thermoplastic elastomer is molded in advance to form a grain in a predetermined mold, and after this is set in the mold of an injection molding machine, a polypropylene composite resin that has been given high rigidity is injection molded to create a laminate molded product. There is a way to do it. Another method is to co-extrude a thermoplastic elastomer and a polypropylene composite resin to form a laminate sheet and then perform heat vacuum forming or the like to form a laminate molded product having grains on the surface.

め層間で充分な接着強度が得られない問題もある。In either case, these methods involve a two-step process in which sheets are formed in advance and then formed into a predetermined laminate molded product, resulting in high costs. Particularly in the case of injection molding, the thermoplastic elastomer layer is not in a molten state, so there is a problem that sufficient adhesive strength cannot be obtained between the layers.

We conducted extensive research to develop a low-cost laminate molded product that has high rigidity on one side, flexibility on the other side, good interlayer adhesion, and can form good grains. As a result, the inventors have found that the above problems can be solved by laminating a specific polypropylene composite resin and a thermoplastic elastomer in a specific manufacturing process. The present invention was completed based on this knowledge.

A thermoplastic elastomer of 04 to 5 x 106 (dyne/C [IT)] was co-extruded from a 2JiT die so that the thickness of the thermoplastic elastomer was 0.2 to 1.5 mm, and placed in the mold. A laminate molded product is provided by supplying and thermally compressing the molded product. Further, the present invention provides a method in which the polypropylene composite resin and the thermoplastic elastomer are diced into a two-layer T die so that the thickness of the thermoplastic elastomer is 0.2 to
The present invention provides a method for producing a laminate molded product, which comprises coextruding the product to a thickness of 1.5 mm, and then supplying the product into a mold and thermally compressing it.

If it is less than 50% by weight, it is difficult to obtain sufficient rigidity, and if it exceeds 50% by weight, problems such as decreased impact resistance and poor appearance may occur. In addition, as an inorganic filler,
At least one of the above calcium carbonate, talc, and glass fiber may be used alone, or two or three types may be used in combination. The type and blending amount can be set as appropriate.

Select within the mm range. If the layer thickness is less than 0.2 mm, the cushioning properties of the laminated molded product deteriorate and at the same time it becomes difficult to form grains. - If the thickness of the old layer exceeds 1.5 mm and the thickness of the laminated molded product is regulated, the thickness of the polypropylene composite resin layer will be relatively thin.
There may be cases where the rigidity is insufficient.

る。The above-mentioned polypropylene composite resin and thermoplastic elastomer are coextruded from a commonly used two-layer T die by a well-known melt extrusion means, and then supplied into a mold, for example, into a mold forming a predetermined grain pattern, At the same time as molding, thermal compression is performed and laminated. In this thermal compression molding, when forming grains on the surface of the elastomer layer, for example, it is necessary to set appropriate conditions such as compression pressure, temperature, and mold clamping time in order to ensure that the grains are transferred from the mold. However, the viscosity of the thermoplastic elastomer layer is a particularly important factor. Therefore, in the present invention, the temperature is 180°C and the frequency is 0.
Dynamic viscosity at 1 rad/sec is 10' to 5
X 10'dyne/cIfl, preferably 104~
A thermoplastic elastomer of 106 dyne/c+fl is used. If the dynamic viscosity is less than 10' dyne/cJ, the viscosity is too low, and the tension during melt extrusion from the T die before molding is insufficient, making it impossible to obtain a uniform layer thickness. Also, the dynamic viscosity is 5 x 106dyne/cT
! If it exceeds l, it becomes difficult to form patterns such as grains.
