Description

Description: TECHNICAL FIELD OF THE INVENTION The present invention relates to a plastic tile having a deep joint pattern, and a method for mass-producing such a plastic tile.

[Conventional technology and technical problems to be solved]

Conventionally, as a means of applying design makeup to the floor surface,
It is known to lay ceramic tiles and natural stones, or linoleum and plastic tiles. However, these floor decorative materials have the advantage that a robust and beautiful joint pattern can be formed on the floor surface, for example, in the former method of using ceramic tiles or natural stones, but on the other hand, material cost and construction cost are very high. In addition to being expensive, it requires a high degree of skill in construction, and in the latter method using linoleum or plastic tiles, the construction is easy and the cost of materials and execution is low. On the other hand, there are advantages, but the design that can be expressed tends to be “thin and thin” and monotonous, and it is practically impossible to draw a beautiful contrasting joint pattern like when using ceramic tiles and natural stones. It had been. Of course, it was possible to print a joint pattern on the surface of linoleum or plastic tiles by the printing method, but the pattern itself does not seem to be fake, and in terms of durability it was decided that the pattern would easily peel off due to abrasion. There was a difficult point.

In view of the poverty of the conventional plastic tile as described above, the present invention has been made to overcome this, and provides a plastic tile having a beautiful and beautiful joint pattern. Is a technical issue.

Another technical object of the present invention is to provide a new method capable of efficiently and inexpensively manufacturing a plastic tile having a beautiful joint pattern.

Further, another technical object of the present invention is to provide a method capable of stably mass-producing joint pattern plastic tiles with little quality variation.

[Means adopted for solving the problem]

Means adopted by the inventor for solving the above technical problems will be described below with reference to the accompanying drawings.

That is, according to the present invention, a joint sheet 1 made of a thermoplastic synthetic resin punched out in a multi-hole shape is hot pressed in a reduced state onto a surface of a tile resin material 2 having a color tone different from that of the joint sheet. By adopting the laminating means of
We have succeeded in providing a plastic tile having a textured and beautiful joint pattern. Further, a thermoplastic synthetic resin sheet for forming joints is punched out in a multi-hole shape to obtain a joint sheet 1, while this joint sheet 1 is used. , And put them on the tile resin material 2 having different colors,
Of the joint pattern which can be pressed to the welding temperature of the joint sheet 1 and then press the joint pattern of the joint sheet 1 into a planar shape.
, And the joint sheet 1 is hot-pressed so that the joint sheet 1 and the raised portions 31, 31 ... By adopting the stepwise means, it was possible to mass-produce the joint pattern plastic tile with a beautiful joint pattern at low cost.

〔Example〕

Hereinafter, the present invention will be described in more detail with reference to the embodiments shown in the accompanying drawings.

In the drawing, what is designated by reference numeral 1 is a joint sheet which is obtained by punching out a thermoplastic vinyl chloride resin sheet colored in a mouse color with a punch type called Thomson.

The reference numeral 2 indicates a tile resin material in which an upper layer 21 made of vinyl chloride resin and an underlayer 22 made of a vinyl chloride resin base material with a high filling material called Anco are laminated.

Further, what is designated by the reference numeral 3 is a pressing die, and the joint surface ridges 31 and 31 formed on the pressing surface to have a shape size substantially the same as the joint pattern of the target sheet 1 or a slightly larger shape size. ... is provided. The shape size of the raised portions 31, 31 ... Of the die 3 is made slightly larger than the joint pattern formed by the joint sheet 1 because the finish at the joint becomes beautiful when hot-pressed. This is because it is effective in preventing the joining error of No. 1. In the illustrated embodiment, the raised portion of the die 3 is
Fine concavo-convex coining is applied to the surface of 31 because this is effective for giving a real feeling when the joint sheet 1 is bonded onto the tile resin material 2.

In this embodiment, the joint sheet 1 is overlaid on the upper layer 21 of the tile resin material 2 and heated to 150 to 160 ° C. to match the raised portions 31, 31 ... Of the die 3 with the joint sheet 1. That is, when hot pressing was performed at 30 kg / cm ² for 15 minutes, a plastic tile having joint patterns P like tiles arranged in a layered structure was obtained as shown in FIG. 3, and tile resin was provided between the joint patterns P. The upper layer 21 of the ground 2 was exposed and had an orderly design.

The embodiments explicitly described in the specification of the present application are generally as described above, but the present invention is by no means limited to the above-mentioned embodiments, and various modifications can be made within the scope of the claims. Then, for example, a concrete pattern of the joint sheet 1 produced by punching is divided into tile patterns (patterns in which tiles are randomly divided into irregular shapes and spread: see FIG. 5).
It is natural that the arrangement can be made according to the request of the product design by changing the color or changing the color, and the material of the joint sheet and the tile resin material 2 is also conventionally used for the plastic tile and the floor sheet. Needless to say, well-known synthetic resin materials are selected according to design convenience.

[Effect of the present invention]

According to the present invention, as described in the above examples, since the joint sheet having a uniform structure is joined and integrated by the hot pressing effect in the reduced state in the tile resin ground,
The joint pattern plastic tiles obtained are structurally stable and strong, and it is possible to mass-produce those that have a deep joint pattern that is rich in actuality with high efficiency. Therefore, the manufacturing cost can be reduced and the cost can be reduced.

Further, the joint pattern plastic tile obtained by the present invention has a high sense of design in spite of being as easy to construct as a conventional plastic tile, and thus is constructed using a ceramic tile or a natural stone. Even if compared with, it is possible to apply beautiful floor make-up, even if it is slightly inferior.

As described above, the present invention can break the limit of the conventional floor tile makeup of plastic tiles, and it can be said that its industrial utility value is extremely large.
