Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composition vinyl floor tile (CT) having high designability.

[0002]

2. Description of the Related Art CT is based on JIS A5 with a resin content of 30% or less.
705 is the floor tile. Conventionally, CT is an inexpensive tile, and the design property of a homogeneous vinyl floor tile (HT) is higher. When increasing the number of transparent parts or translucent parts, a method of increasing the amount of resin to increase the transparency was adopted, and it was inevitably in the category of the homogeneous style. In addition, since the method of manufacturing HT is generally a press method, the efficiency is poor.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to obtain a tile having a high design property while being a CT.

[0004]

SUMMARY OF THE INVENTION The present invention provides a composition vinyl floor tile having a colored opaque pattern portion,
A method for producing a floor tile comprising a translucent pattern portion having an opaque filler amount of 30 to 70% by weight and containing talc of 10 to 50% by weight, and a composition vinyl floor tile, comprising: And a calender-rolling translucent patterned chip mixture containing 30 to 70% by weight of opaque filler and 10 to 50% by weight of talc.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The CT of the present invention is constituted by a combination of an opaque pattern portion and a translucent pattern portion. The opaque pattern portion has the same components as the conventional CT, and the resin amount is 30%.
It is obtained by pelletizing a colored sheet containing less than 70% by weight of an opaque filler such as calcium carbonate, clay, silica or the like in an amount of less than 10% by weight.

The translucent pattern material has a resin content of 15 to 30% by weight.
Wherein the amount of the opaque filler is 30 to 70% by weight;
Talc, which is a translucent filler, is contained in an amount of 10 to 50% by weight. In the present invention, the resin is made of ordinary polyvinyl chloride (P
VC), but polyolefins such as polyethylene, polypropylene and ethylene-vinyl acetate copolymer (EVA) can also be used. The semi-transparent pattern portion and the opaque pattern portion in the present invention are preferably in a state of a chip described below, but a lump larger than that may be used.

In the method for producing CT, a colored opaque pattern chip and a translucent pattern chip mixture containing 30 to 70% by weight of opaque filler and 10 to 50% by weight of talc are calendered. It is characterized by. The resin amount of the entire CT is less than 30% by weight, specifically 15 to 30% by weight, but in the case of a translucent chip, the resin amount is 15 to 30% by weight and the opaque filler amount is 30 to 30% by weight.
70% by weight, and 10 to 50% by weight of talc.

The opaque pattern chip has a resin amount of 15 to 30% by weight and an opaque filler of 70 to 85% by weight as in the conventional CT. The obtained chip mixture is heated at 100 to 200 ° C.
And calender rolling. In the present invention, the resin amount is the total amount of the resin and the plasticizer.

In particular, in the method for manufacturing a floor tile of the present invention,
After creating a flow pattern sheet of opaque or translucent pattern chips, spraying large chips of the component opposite to the components constituting the sheet on the sheet, and rolling the marble,
A terrazzo pattern is obtained. When the sheet has a translucent pattern, the large chips are opaque, and when the sheet is opaque, the large chips are translucent. The large chip is 15 to 100 mm
It is larger than the diameter. This sheet is usually formed by small chips of 10 to 100 mesh.

FIG. 1 is a front view of a terrazzo-patterned tile according to the present invention. In FIG. 1, hatched 1 is a large translucent chip, and a large chip pattern of a translucent resin composition is integrally formed with an aggregate pattern of small opaque chips 2. Thus, high floor tiles 4 made of a design such as a terrazzo pattern are continuously obtained. The translucent large chip can appropriately obtain a colored pattern such as a striped pattern. 3 is a base sheet. The base sheet may be another colored sheet or the above-mentioned small chip aggregate.

The method of forming a granite pattern is a method of manufacturing a floor tile in which a chip having a component opposite to a component constituting the chip is applied to an aggregate of chips having an opaque chip pattern or a translucent pattern and rolled. In this case, the size of the chip is relatively small and has a diameter of 1 to 15 mm.

FIG. 2 is a surface view of the granite pattern tile of the present invention. The pattern mixture of the medium-sized translucent chips 5 and the opaque small chips 6 is calendered, and a three-dimensional granite pattern 7 can be obtained.

In the present invention, the above-described pattern formation may be performed so as to satisfy the condition of the CT component as a whole. In the manufacturing process, calender roll rolling can be performed, which is efficient. Unprecedented design CT was obtained at low cost.

[0014]

(Example 1) Table 1 Table 1 A20 mesh three-color opaque small chips of 20 colors were preheated and rolled at 150 ° C. to form a 4.5 mm thick sheet. Large chips (50 mm diameter) are spread and rolled, traversed, and then calender rolled to obtain a sheet with a pattern in which the large chips are embedded between the small chips. A pattern CT was obtained.

[0015]

[Table 1]

(Example 2) A three-colored opaque chip of Formula A in Table 1 and a small chip having a diameter of 1 to 2 mm were mixed in each of the semi-transparent chips of Formula B in Table 1 at 150 ° C. It was heated and rolled, cut, traversed 90 degrees, and further rolled to make the vertical and horizontal patterns elongate. As a result, a granite pattern sheet was obtained, and this was cut into the above-mentioned tile shape to obtain CT.

[0017]

According to the CT, a terrazzo pattern or a granite pattern having a high design property was obtained for the first time. In the manufacturing process,
Calender roll rolling is possible and efficient. Unprecedented design CT was obtained at low cost.
