The joint material of the present invention is arranged between the panel materials, and is characterized by the joint exposed portion which is mounted between the panel materials and constitutes the surface thereof.

The joint exposed portion made of a soft elastic body is a member constituting the surface side of the joint material, and is mounted between the panel materials to elastically fill the gap. Therefore, the joint can be directly decorated by blending the decorative base material in the joint exposed portion. The main material of the soft elastic body of the present invention may be one that can elastically fill the gap between the panel materials, and specifically, soft vinyl chloride resin, olefin elastomer resin, urethane-modified vinyl chloride. Examples thereof include resins, and among them, soft vinyl chloride resin is preferable from the viewpoint of extrusion moldability. The soft elastic body may further contain a plasticizer such as DOP and DIP, a filler such as calcium carbonate, a pigment, a lubricant, and the like. Further, the color of the soft elastic body can be appropriately selected in consideration of the appearance of the panel material and the like.

More preferably, it is a ceramic chip made mainly of aluminum oxide. It is preferable that the ornamental base material is in the shape of a chip because it is easy to be oriented in a flat shape during extrusion and has a good external appearance.

The ceramic chips may contain suitable coloring agents and other additives. These coloring materials and the like may be applied to the surface of the ceramic chip, or may be mixed with the ceramic powder and molded into a chip shape.

The external dimensions of the ceramic chip are preferably 200 μm or more and 5 mm or less. If it is smaller than 200 μm, the effect of forming a pattern on the joint exposed portion is small, and if it exceeds 5 mm, it becomes difficult to form the pattern when the width dimension of the joint is taken into consideration. This is because the moldability is reduced.

In addition, the compounding amount of the ceramic chip is 0.1 to 100 parts by weight of the main material of the soft elastic body.
5 parts by weight are preferred. Less than 0.1 parts by weight,
This is because the chips become inconspicuous, and when the amount exceeds 5 parts by weight, the extrusion moldability is deteriorated due to clogging or the like.

More than one kind can be included, and a plurality of decorative substrates can be combined. In this case, the size of the decorative substrate,
By changing the color tone and the blending amount, various design surfaces can be given to the joint exposed portion.

Further, the joint exposed portion may be divided into a central portion and both end portions on both sides thereof. As a result, it becomes possible to change the pattern between the widths of the joints along the end faces of the facing panel materials. That is, by changing the color tone of the soft elastic body and the type, shape, color tone, and blending of the decorative base material to be blended between the central portion and both ends thereof, the pattern is gradually changed between the joint widths. be able to.

As described above, it is preferable that the joint exposed portion formed of the soft elastic body containing the decorative base material is formed by extrusion molding. The extrusion molding is convenient for forming the elongated shape of the joint exposed portion, and the joint exposed portion usually has a support portion for supporting the joint exposed portion between the panel materials. For this reason, extrusion molding is suitable for integrally forming the support portion and the joint exposed portion in a long shape.

The weather-resistant transparent film of the present invention is preferably a transparent or semi-transparent resin film and is applied to the surface of the joint exposed portion. The type of can be selected. Specifically, when the main material of the soft elastic body at the joint exposed portion is vinyl chloride resin, a transparent vinyl chloride resin is preferable, and when it is an olefin elastomer, ethylene vinyl acetate resin is preferable.

In order to apply the transparent film to the surface of the joint exposed portion, it is preferable that a transparent resin be molded and coated at the same time as the extrusion of the joint exposed portion. Alternatively, the film can be formed by integrally laminating a transparent film on the surface of the joint exposed portion in a molten state at the time of extrusion or by coating with an acrylic or urethane type.
