[0002]

2. Description of the Related Art Interior linings for automobiles are usually injection-molded from synthetic resins such as polypropylene (PP), ABS resin and thermoplastic elastomer. A skin layer such as leather can be laminated and adhered to the outer surface.

[0003] These vehicle interior linings are often colored black in design. The vehicle interior lining is colored black by adding carbon black to the material. As described above, since the interior lining for a vehicle is generally colored by adding carbon black, it can be manufactured very inexpensively and has the characteristics of being stable in physical properties.

[0004] However, when the vehicle is left under the scorching sun, particularly in a high temperature region such as Asia, the carbon black in the vehicle interior lining absorbs sunlight and the temperature of the surface of the vehicle interior lining rises extremely. When the driver starts driving after parking for a long time, he or she touches the interior lining of the vehicle with his / her hand, which gives the user discomfort.

Therefore, it has been attempted to form a vehicle interior lining by adding a white pigment to the vehicle interior lining material. Thus, as can be seen from the results of FIG. 6 described later, it is known that the surface temperature rise when the vehicle is left under the scorching sun is suppressed as compared with the case where carbon black is added.

However, there is a design problem in that the use of a white vehicle interior lining in a cabin in which the color scheme of the interior of the automobile is unified with a dark color such as black results in a poor balance of the interior design. Therefore, in recent years, there has been a demand for the development of a black interior lining for a vehicle in which the surface temperature does not easily rise even when the vehicle is left in the scorching sun.

Next, in order to confirm the operation and effect of the present invention, a comparison was made between an embodiment of the present invention and a vehicle interior lining 3 as a conventional example, which will be described below.

Example 1 In this example, a vehicle interior lining 3 formed by adding a commonly used black pigment to a thermoplastic elastomer (TPE) and a vehicle formed by adding an infrared reflective pigment of the present invention are formed. The interior lining 3 was illuminated with incandescent bulbs to compare how the surface temperature of each skin layer increased.

As the vehicle interior lining according to the present invention, a thermoplastic elastomer (TPE) obtained by adding an infrared reflective pigment to an injection molding (black of the present invention) was used.
Further, as a conventional example, a thermoplastic elastomer (TPE) to which a black pigment (carbon black) or a white pigment is added (conventional black, conventional white) was used.

These materials were prepared as test pieces. These test pieces were irradiated with incandescent spheres to measure the change over time in the test piece surface temperature. Thereafter, the incandescent bulb was turned off, and a change with time of the test piece surface temperature for 5 minutes after the light was turned off was measured. The temperature was measured using a thermoviewer.

FIG. 6 shows the results of comparison performed by the above-described samples and methods. As can be seen from FIG. 6, when the temperature of the conventional product (black) is increased to 90 ° C. by irradiation of the incandescent lamp, the surface temperature of the product of the present invention is increased by 10 ° C. to 25 ° C. as compared with the conventional product (black). Could be suppressed. At this time, the surface temperature difference from the conventional product (white) was about 2 to 5 ° C., and the surface temperature rise could be suppressed to almost the same level as when the white conventional product was used.

As described above, the product of the present invention (black) having the interior lining for a vehicle according to the present invention has a surface temperature as low as that of the conventional product (white) despite being black when left in the scorching sun. I found that I could do it. Here, the thermoviewer refers to a radiation-type thermometer.

As described above, in the present invention, since the infrared reflective pigment is added to the vehicle interior lining, even if the vehicle interior lining is black, the vehicle interior lining can be left unattended under the scorching sun. The surface temperature of the lining hardly rises. Therefore, even when driving is started after leaving the vehicle under the sunshine, when the vehicle interior lining is touched by hand, it does not feel hot and uncomfortable.

Further, according to the present invention, it is possible to prevent the temperature of the surface of the vehicle interior lining from rising in the hot sun without making the color of the vehicle interior lining white, so that the color of the vehicle interior lining can be selected. It is possible to prevent the temperature of the surface of the vehicle interior lining from rising under hot weather without reducing the degree of freedom. In addition, it can be adapted to the recent trend in the interior design of automobiles, and does not impair the sense of quality in the interior of the automobile.

Further, in the present invention, the surface of the skin layer of the vehicle interior lining is formed as an uneven squeezed pattern. When touched, heat can be hardly felt.
