  • a plasticizer Based on 100 phr of the PVC resin, 25 phr of a plasticizer, 50 phr of calcium carbonate, 10 phr of titanium dioxide, and 3 phr of a stabilizer were mixed by means of a Banbury mixer and then subjected to first and second mixing by means of a 2 roll machine. Subsequently, a prepared material was subjected to calender molding at 160°C, thereby preparing a white sheet having a thickness of 0.10 mm. In addition, a printed pattern was formed on a white sheet surface by gravure printing or reproduction proof printing, thereby preparing a printed layer.
  • composition for preparing a base layer was subjected to calender molding at 160°C, thereby preparing a base layer having a thickness of 2.60 mm.
  • the prepared transparent layer, printed layer, base layer, and easy layer were sequentially stacked and then laminated through application of heat and pressure using a lamination process, thereby preparing a PVC tile including polyester fiber.
  • a sectional view of the tile according to the example is schematically illustrated in FIG. 3.
  • a transparent layer, a printed layer, a base layer, and an easy layer were respectively prepared in the same composition and method as the above example, except that the base layer was not mixed with a polyester fiber. Subsequently, the layers were thermally laminated, thereby manufacturing a tile as a comparative example.
  • the base layers used in the example and the comparative example and the tiles (complete products) manufactured according to the example and the comparative example were respectively subjected to a long-term residence test (Lab) at 80°C.
  • a dimensional change rate in a length direction (L) was measured.
  • the dimensional change rate was measured as follows: ⁇ (vertical length upon measurement - vertical length at day 0)/vertical length at day 0 ⁇ X100.
  • the dimension of the base layer of the example including the polyester fiber is constantly maintained without an additional dimensional change, whereas the dimension of the base layer of the comparative example excluding the polyester fiber is continuously changed.
  • the base layer of the comparative example shows a greater dimensional change rate, compared to the base layer of the example.
  • the tile, as a complete product, of the example shows a smaller dimensional change rate compared to the tile of the comparative example, and, over time, a dimensional change of the tile of the example is smaller than that of the tile of the comparative example as time goes on.
  • the tile of the example and the tile of the comparative example were constructed in an indoor floor that may be heated. Subsequently, over time after floor heating, the sizes of gaps between tiles were observed. Upon floor heating, surface temperatures of the constructed tiles of the example and the comparative example were 47 to 55°C.
  • the base layer occupying the largest part of a whole structure of a PVC tile according to the present invention includes polyester fiber, and thus, overall dimensional stability of the PVC tile is increased.
  • the PVC tile can be applied to floor materials for home use.
  • the PVC tile according to the present invention uses polyester fiber that does not affect processing of a PVC resin, mixing and molding may be carried out after directly adding polyester fiber to a composition forming the base layer of the PVC tile. Accordingly, a process of forming a separate dimensional-stabilizing layer and laminating the same is not required, thereby simplifying a manufacturing process.
  • the base layer including a PVC resin and an additive includes polyester fiber, a weave remainder from other woven polyester or weave discarded after being used may be reused, thereby providing environmental protection and cost reduction effects.
