Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an automobile interior product, and more particularly to an automobile interior product that is a molded product made of a core material and a skin. Examples of automobile interior parts include center clusters, power window switch panels, and ashtray surface panels.

[Conventional technology]

The real wood products made from real wood are light and easy to hit (unlike plastic, they have a high-class feel) and have a deep design, so from a texture, it can be said that they are suitable for automobile interior parts. . 2. Description of the Related Art Conventionally, when a real wood product is used as an automobile interior part, for example, FIG. 4 shows a panel of a power window switch, and FIGS.
Although it is a cross-sectional view taken along line A, as shown in FIG. A wooden adhesive sheet (2) is coated with a liquid adhesive, laminated, and then hot-pressed to form a shape, and then a transparent coating layer 3 is formed to manufacture. Further, as shown in FIG. 6, part of the single plate 1 of the core material is replaced with the aluminum plate 4.

[Problems to be solved by the invention]

Generally, the wood products have the drawback of high cost. Also, the fifth
Since the wood products of the type shown in the figure are thermally deformable and have poor dimensional stability, it is necessary to increase the plate thickness in order to use them as automobile parts. There is no problem. On the other hand, the type shown in FIG. 6 prevents thermal deformation by the aluminum plate 4, but has a problem in that it is easy to peel off at the aluminum plate due to poor adhesion between aluminum and wood and the weight becomes heavy. There is. Further, in any of the cases of FIG. 5 and FIG. 6, there is a problem that the adhesive (liquid) seeps out to the surface veneer and deteriorates the design.

[Means for solving problems]

In order to solve the above-mentioned problems of the prior art, the present invention aims to prevent the resin impregnated in the kraft paper from seeping out on the front and back surfaces of the core material laminated with the resin-impregnated kraft paper. Provided is an automobile interior product, which is formed by forming a laminated plate on which a skin material of the same quality is attached via a sheet, and which has a transparent coating layer on the surface skin material.

[Action]

The product according to the present invention can have the same texture as a real wood product by using the surface veneer of the real wood as the skin material, but the cost is reduced because the material is inexpensive and the adhesive application process is unnecessary. Since the resin-impregnated kraft paper has excellent dimensional stability, the plate thickness can be reduced and the weight can be reduced. In addition, dimensional stability became more complete by providing the same quality skin material on both front and back surfaces.

〔Example〕

An embodiment of the present invention will be described with reference to FIGS. 1 and 2. Second
The figure is an enlarged view of a portion B surrounded by a circle in FIG. In these figures, 2 is a veneer surface veneer, and 3 is a transparent coating layer, which is the same as the conventional example. Reference numeral 5 is kraft paper impregnated with a resin such as phenol, which is used in place of the wood veneer 1 or the aluminum plate 4. The resin-impregnated kraft paper 5 has a quality comparable to real wood products, is cheaper than real wood veneer, and can be made as thin as 0.1 mm, and by stacking it, it is strong and good. It is possible to obtain a laminate having excellent dimensional stability.

In the product of the present invention, as an application, if necessary, a vinyl chloride print sheet or the like may be used instead of the surface veneer 2 of the real wood to reduce the cost. Further, by replacing a part of the kraft paper 5 with a resin plate such as phenol, it is possible to further improve the dimensional stability and reduce the cost of the material. It is preferable that the kraft paper and the resin plate are alternately laminated.

In the figure, 6 is an adhesive sheet that prevents resin from seeping out from the kraft paper to the skin material 2. This sheet 6
Also contributes to dimensional stability. This is because the kraft paper 5 is a sheet 6 when the surface veneer 2 is deformed by heat pressing.
This is because it is possible to follow through. Further, in the present invention, in order to further improve the dimensional stability, the kraft paper 5
Sheets 6 are placed on both sides of the sheet, and front and back single-sided veneers 2
It is desirable to use the same material. By doing so, it is possible to reduce the deformation by balancing the deformation forces on the front and back during heating.

FIG. 3 illustrates a manufacturing process of a product (panel of a power window switch) of such an embodiment. The resin-impregnated kraft paper 5, the sheet 6, and the surface veneer 2 are laminated in a predetermined number and in order (step I), and they are hot-pressed (step II), and then punched out and cut to finish into a predetermined shape, Further, color painting and coating are performed (step III). In the product of the present invention, since the kraft paper 6 is impregnated with the resin, the application process of the adhesive is unnecessary, and the manufacturing cost can be reduced.

[Effect of device]

According to the present invention, (1) there is provided an automobile interior product including a core material and a skin having a high-quality feeling similar to that of a real wood product, and (2) dimensional stability can be improved without increasing the plate thickness. ,
(3) Cost can be reduced by using low cost materials and omitting the bonding process, (4) Light weight (compared to using aluminum plates) can be used, and (5) Small plate thickness Because it is possible, the degree of freedom of design is improved, and also (6)
The addition of the sheet has the effect of preventing the adhesive from seeping out from the surface veneer and improving the color development.
