  • Patent number: 11312855
    Abstract: The present invention relates to a resin composition containing a polyvinyl chloride resin and an acrylic resin and a board for interior materials manufactured using the same. More specifically, the present invention relates to a resin composition having excellent heat resistance due to a high glass transition temperature, having high flexibility even with a low plasticizer content, and having excellent processability due to such properties, as compared with the case wherein a polyvinyl chloride resin is used alone, and to a board for interior materials manufactured using the resin composition. According to the present invention, the resin composition may be applied to both a calendering method and an extrusion method due to excellent processability thereof.

  • Patent number: 8980149
    Abstract: The present invention relates to a method and device for manufacturing artificial stone. More specifically, the method includes the steps of: (a) mixing two or more kinds of chips having different grain sizes with a raw material for artificial stone; (b) injecting the raw material for artificial stone mixed with the chips into a mold; (c) applying primary vibration using a vibration device such that the raw material is uniformly dispersed in the mold; (d) applying vacuum to eliminate bubbles in the raw material; and (e) molding artificial stone by applying a secondary vibration using the vibration device. According to the method and device for manufacturing artificial stone of the present invention, the deposition rate of chips exposed at a surface of artificial stone is maximized, and thus the external appearance of artificial stone can be more naturally expressed and resistance against abrasion and staining can be improved.

  • Publication number: 20150044409
    Abstract: Disclosed therein is a floor panel having an adhesive applied sheet, which can be constructed without carrying out an adhesive applying process because the adhesive applied sheet is adhered on a rear side of the floor panel in the process of manufacturing the floor panel, which is easy to be removed and recycled because an adhesive is not applied to the floor during construction, and which can enhance consumers' satisfaction because it uses environment-friendly materials.
