、重量増加が問題になる。1. Prior Art As is well known, the tonneau board of an automobile as shown in FIG. 1 is exposed to direct sunlight, and therefore becomes quite hot when parked on the street in the summer. Therefore, if the tonneau board was made of a general molded resin board, it would be extremely hot and uncomfortable if you accidentally touched it with your hands or skin.
A tonneau board is constructed by painting a wood plywood or bar board veneer l as shown in the figure (for example, the Nissan Knee 811 car). However, these tonneau boards do not maintain their rigidity even at extremely high temperatures. Since it does not deteriorate, it is possible to use a relatively thin and lightweight material, but due to its hygroscopicity, it may warp after absorbing moisture.For this reason, conventionally, polypropylene resin was used. It is also being considered to use wood-based polypropylene composite resin boards as shelf materials, which are made by mixing and molding wood materials such as wood powder and crushed wood chips into a mixed resin whose main component is wood-based polypropylene composite resin. The board exhibits stable properties against changes in humidity, but when exposed to high temperatures for a long period of time, the mixed resin softens and ``deflects'', and this ``deflection'' persists even after returning to room temperature. Because there is a risk that recovery will not occur,
For safety reasons, a thick plate must be used, which increases the weight.

In view of the above-mentioned problems with conventional automobile shelf materials, an object of the present invention is to provide an automobile shelf material that is relatively lightweight and does not cause "warpage" due to changes in humidity. It is in.

It is proposed to weld the parts around the periphery.

（−利専があ−る。The wood-based vinyl chloride composite resin board 3 that covers both surfaces of the wood core material 2 is made by mixing wood powder such as wood powder, crushed wood pieces, partifrubo, and surface polishing powder in a resin mainly composed of vinyl chloride. It is obtained by mixing approximately equal weight percent and heating molding, and has a width and length slightly larger than the wood core material 2, and the resin board 4 is mainly made of vinyl chloride. These are molded resin plates, and the peripheral parts of both resin plates 3 and 4 are welded together using heat pressing or high frequency welding. That is, the wood-based vinyl chloride composite resin board 3 on the outside side preferably has the structure described above in terms of appearance and feel, but the resin board 4 on the back side is not necessarily limited to the above-mentioned structure. Rather, from the point of view of impact resistance as a tonneau board, it is better to use a wood-based vinyl chloride composite resin board with a lower proportion of wood for impact resistance.
(There is Risen.

芯材２は常に均一な湿度条件下におかれる。Since the automobile shelving material according to the embodiment has the above-described structure, the wood-based vinyl chloride composite resin board 3 and the resin board 4 mainly composed of vinyl chloride have a property of softening at high temperatures, but the wood core Since the rigidity of material 2 hardly changes due to temperature changes, the rigidity of both resin plates 3.4 at high temperatures
There is no deflection. In addition, even when the temperature changes are large, the wood core material 2 is covered with the wood-based vinyl chloride composite resin board 3 and the resin board 4, so "warping" is prevented, and the wood core material 2 is always kept under uniform humidity conditions. be put down.

使用し、衝撃に対し強いものとすることもできる。In the above embodiment, wood-based vinyl chloride composite resin of the same quality was used on the front and back sides of the core material, but one side may be made of a material that does not contain wood powder to make it strong against impact.

It is possible to obtain a lightweight product that does not cause "sagging or warping" due to changes in temperature or humidity.
