The present invention is made of a plurality of layers including a glass fiber layer and a semi-foaming layer, and relates to a floor tile having excellent dimensional stability and cushioning properties.

Generally, polyvinyl chloride-based floor tiles may be classified into mixed vinyl floor tiles and homogeneous vinyl floor tiles according to the content of the binder. When the binder content is less than 30% by weight, It is a vinyl floor tile and, if it exceeds 30% by weight, it is a homogeneous vinyl floor tile (here, the binder refers to a vinyl resin, a plasticizer, and a stabilizer). The former is characterized in that it does not have a laminated structure, and manufacturing is usually performed through a calender method. The latter has a laminated structure, manufactured through the calender method and the sol method, and recently, a product having improved dimensional stability through lamination of glass fibers has been introduced.

The characteristics of the existing floor tiles have been satisfied with the needs of consumers by emphasizing convenient construction and durability, but because they have a limit in walking feeling, they have been mainly used in places carrying public-oriented shoes.

The present invention is devised to solve the problems of the conventional floor tiles as described above, the object of the present invention is to provide a floor tile that satisfies both the cushioning and dimensional stability of the existing warning line floor tiles and the construction and durability of the floor tiles. To provide.

Semi-foaming used in the present invention exhibits a foaming ratio of about half (100-200%) compared to conventional foaming (200-400%) in terms of foaming ratio, and there is a difference in terms of performance of the cushion compared to conventional foaming. . General foaming imparts cushioning properties by using chemical foaming agents, and gives a strong cushioning property due to a weak resistance to external pressure, but has a limit in restoring force when releasing external pressure, while semi-foaming provides cushioning properties using physical foaming agents. The resistance to external pressure is very strong, giving a relatively weak cushioning property, but the restoring force is excellent when the external pressure is released.

General foaming in the manufacturing process is required to meet the temperature conditions of about 200 ℃ due to the characteristics of the chemical foaming agent, the foaming occurs, but semi-foaming is possible because the foaming is possible above the PVC softening temperature (50 ~ 70 ℃) it is possible to low-temperature foaming. The semi-foaming layer is obtained by adding 0.1 to 5 parts by weight of a physical foaming agent to a conventional layer formulation, followed by coating and foaming at 100 to 250 ° C.
