Description

The present invention relates to an exterior panel. That is, the present invention relates to an exterior plate attached to, for example, a lower part of a front of an automobile or a railway vehicle.

[Background Art] As such an exterior plate of an automobile or a railway vehicle, a plate obtained by processing an iron plate into a predetermined shape on a metal plate or the like and coating the surface thereof has been generally used. Recently, in order to reduce the weight and improve the corrosion resistance and the like, an exterior plate obtained by processing reinforced plastics into a predetermined shape instead of a metal plate such as an iron plate has been developed and used.

"Problems to be Solved by the Invention" By the way, the following problems have been pointed out with respect to such an exterior plate using reinforced plastics.

That is, it has been pointed out that the hardness is low and the wear resistance is poor. And in the case of cars and railway vehicles,
During traveling, stones, sand and other objects on the road surface jump up or come in contact with other stationary objects or animals, etc., so that, for example, the exterior plate attached to the lower part of the front etc. is easily damaged, In particular, in the case of an exterior plate using reinforced plastics, wear and tear were severe and deterioration of appearance was a problem.

 In the prior art, such a point was pointed out.

The present invention has been made in view of such circumstances, and has been made to solve the above-described problems of the conventional example. A coating layer containing ceramic particles densely in a resin in almost a contact state is provided by a reinforced plastic material. An object of the present invention is to propose an exterior plate having excellent abrasion resistance and the like by being formed on a base material.

"Means for Solving the Problems" The technical means of the present invention for achieving the object is as follows.

This exterior plate has a coating layer formed on the surface of a base material made of reinforced plastics, and the coating layer contains ceramic particles densely in a molten resin in almost a contact state. .

"Operation" The present invention has the following means since it is constituted by such means.

In this package, a coating layer containing ceramic particles densely in a resin almost in contact with the resin is formed on the surface of a reinforced plastic substrate.

As described above, since the coating layer contains a large amount of ceramics and has a high hardness, the surface of the exterior plate is hard to be worn and has excellent wear resistance. Further, since the base material is made of reinforced plastics, this exterior plate is excellent in lightness, and may also contain ceramics in the coating layer, and is excellent in corrosion resistance and the like.

"Examples" Hereinafter, the present invention will be described in detail based on examples shown in the drawings.

FIG. 1 is an enlarged front view of a main part showing an embodiment of the present invention.

 First, the configuration and the like will be described.

This exterior plate 1 is made of a base material 2 made of reinforced plastics.
A coating layer 3 is formed on the surface of the resin layer 5. The coating layer 3 contains particles of the ceramics 4 in the melted resin 5 in a dense state almost in a contact state.

More specifically, the substrate 2 is made of reinforced plastics, that is, FRP. As the ceramics 4, hard oxide-based, nitride-based, carbide-based ceramics and the like are used.
In addition, those having various grain states are used. As the resin 5, for example, a resin which is initially in a particulate form, is melted by heating or the like, and is cured afterwards to exert a bonding function, for example, a resin generally used as an adhesive is used.

For example, the resin 5 melted by the heating and pressurization penetrates and fills the gaps between the large number of particles of the ceramics 4 which are not melted even by the heating and pressurization by the capillary phenomenon and the like, and is strongly joined together. A coating layer 3 as a predetermined composite coating is formed by bonding to a surface of a base material 2 made of plastics. In the coating layer 3 of such an exterior plate 1, the particles of the ceramics 4 are densely contained, for example, at a volume ratio of about 50% or more. The coating layer 3
In order to further increase the bonding strength between the base material 2 and the reinforced plastics, the two parts are separately formed, and the two parts are bonded with a resin adhesive interposed therebetween, which has a particularly high bonding strength. You may make it.

 The above is the description of the configuration and the like.

 Next, the manufacturing method will be described.

The exterior plate 1 is manufactured by, for example, the following first and second manufacturing methods.

The first manufacturing method will be described. First, a base material 2 made of flat reinforced plastics, and a mixture of a predetermined amount of ceramic 4 particles and resin 5 particles,
Prepare Then, a mixture of the particles of the ceramics 4 and the particles of the resin 5 are placed on the surface of the base material 2 in a substantially uniform and appropriate thickness, and then the particles of the resin 5 are melted by heating and pressing. By curing, a predetermined coating layer 3 is formed on the substrate 2. Thereafter, the thus obtained product is subjected to a bending process, a cutting process, and the like, whereby the exterior plate 1 having a predetermined shape, for example, a substantially skirt shape is manufactured.

Next, a second manufacturing method will be described. In this manufacturing method, first, the base material 2 made of flat plastics is subjected to a bending process, a cutting process, and the like, so as to have a predetermined shape, for example, a substantially skirt shape. Then, a mixture of a predetermined large amount of ceramics 4 particles and resin 5 particles prepared in advance is uniformly and appropriately disposed on the surface of the base material 2 having the predetermined shape. Then, the resin 5 is melted and cured by applying heat and pressure, whereby a predetermined coating layer 3 is formed on the base material 2, and thus, the exterior plate 1 is manufactured.

The exterior plate 1 is easily and easily manufactured by the first and second manufacturing methods, and is excellent in cost.

 The above is the description of the manufacturing method.

 Next, the operation and the like will be described.

2 and 3 are schematic illustrations of an example of use of the exterior plate 1 having, for example, a substantially skirt shape. FIG. 2 shows a case where the exterior plate 1 is mounted on a lower front part 7 of an automobile 6, and FIG. This shows a case where the vehicle is mounted on the lower front part 9 of the vehicle 8.

Now, in the exterior plate 1 used in this way, the coating layer 3 which contains the particles of the ceramics 4 in the resin 5 almost in a close contact state and densely is formed on the surface of the base material 2 of the reinforced plastics. ing.

Thus, the coating layer 3 has a high content of the ceramics 4 and a high hardness. Thus, the exterior plate 1 is hardly abraded on the surface and has excellent wear resistance. In addition, this exterior plate 1
Since the base material 2 is made of reinforced plastics, it is excellent in lightness by making use of its characteristics. Further, the ceramic layer 4 may be contained in the coating layer 3 so that it is excellent in corrosion resistance and the like.

 The above is the description of the operation and the like.

"Effect of the Invention" As described above, the exterior plate according to the present invention is such that the coating layer containing the ceramic particles densely in the resin in almost the contact state is formed on the base material of the reinforced plastics. Has the following effects.

That is, since the coating layer has a high ceramic content and a high hardness, this exterior plate has excellent surface wear resistance. Therefore, in the case of automobiles and railway vehicles, stones, sand and other objects on the road surface jump up when traveling, and other stationary objects and animals come into contact. When the board is mounted, the exterior board is hardly worn and damaged by the coating layer, and its appearance is not impaired.

In addition, compared to the conventional case using a metal plate such as an iron plate, the base plate is made of reinforced plastics, so it is excellent in lightness, and since the coating layer contains ceramics, it has corrosion resistance Also excellent.

As described above, the effects exhibited by the present invention are remarkable and large, for example, the problems existing in this type of conventional example are eliminated.
