  • Patent number: 9567757
    Abstract: Disclosed is a laminated floor using a poly lactic acid (PLA) resin, of which a surface layer is formed of the PLA resin, thereby being environment-friendly and providing soft feeling and excellent workability. The laminated floor using a PLA resin, which is constructed on floor, includes a bottom layer formed of a HDF or MDF; and a surface layer comprising a reinforcement layer, a printed layer, a transparent layer and a surface treatment layer which are stacked on the bottom layer, wherein one or more of the reinforcement layer, the printed layer, the transparent layer and the surface treatment layer are formed of the PLA resin.

  • Publication number: 20150050449
    Abstract: Disclosed therein is a flooring, which can secure environment-friendliness by forming a surface layer laminated on an upper face of a base layer using PLA (Poly Lactic Acid) resin instead of wood, easily provide a handcraft surface texture by applying a curved pattern onto the surface of the surface layer using embossing rollers at the time that the surface layer is manufactured, and prevent compression, scratches, discoloration, and so on in comparison with woods. The flooring constructed on a floor of a building includes: a base layer made from one of an MDF, an HDF, and a plywood; and a surface layer having a reinforced layer, a printed layer, and a transparent layer which are laminated on an upper face of the base layer in order, at least one of the layers being made of PLA (Poly Lactic Acid) resin. A curved pattern is formed on an upper face of the surface layer.

  • Publication number: 20130266759
    Abstract: The present invention relates to a flooring material including a PLA surface layer having a wood pattern. The flooring material includes a surface layer including at least one layer containing a PLA resin, a plywood layer including a veneer disposed on the undersurface of the surface layer, and a synthetic resin layer disposed on the undersurface of the plywood layer. The flooring material is cut in a tongue & groove shape.

  • Patent number: 8298654
    Abstract: A tile type flooring in which printing and cutting patterns coincide with each other, and a process for preparing the same. Band pattern portions (32) are respectively formed at neighboring two sides of each of main pattern portions (31) and synchronizing cutting is performed. Thereby, the total width of the band pattern portions (32) of each of tiles is uniformly narrowed. The tile type flooring has an aesthetic external appearance, and the tiles are naturally connected, thus expressing the reality of natural resources and the luxurious appearance. Further, if necessary, the flooring employs a size reinforcing layer (50) and has a transparent layer (20) and a first base layer (40), and a second base layer (60) and a balance layer (70), which are symmetrically stacked on the upper and lower surfaces of the size reinforcing layer (50), thus reducing defects caused by size instability of the flooring.

  • Publication number: 20070166516
    Abstract: Disclosed are a flooring time including a substrate layer, printed layer, and transparent film, which are laminated from the bottom, and concave patterns mechanically embossed on the substrate layer and printed layer at the same time, and a process for preparing the flooring tile. The laminating and embossing operation of the respective layers are successively performed by use of a series of successively arranged rolls.
