たりの工事費が著しく高くなるという欠点があった。In recent years, there has been a demand for flooring materials that are lightweight and have a soft walking feel.For example, vinyl chloride resin foam is known for this purpose.This material is lightweight, which is a disadvantage of general synthetic resin tiles. It is an excellent product that has improved cold sensation, poor heat retention, hard feel when walking, and harsh walking noise, but since this foam uses vinyl chloride resin paste, it is unique to this foam. Flooring materials made of asbestos are too soft and have a poor walking feel, the foam cells on the surface are easily destroyed, the decorative effect is not maintained, and the abrasion resistance and dimensional stability are poor. There are commercially available flooring materials in which the foam and a surface layer made of a material with excellent abrasion resistance such as vinyl chloride film are sequentially laminated and integrated on a base material layer made of a material with excellent stability. The manufacturing process is complicated, the resulting flooring material is expensive, and unlike vinyl chloride tiles, it is not possible to recycle defective products or scraps during the manufacturing process; Since it is in sheet form, there is a large amount of loss during construction, it is difficult to construct, and the construction cost per unit area is significantly higher than that of general synthetic resin tiles.
