Abstract: The present invention relates to resin syrup, which comprises a high-molecular-weight acrylic material containing a carboxyl group, and comprises a room-temperature-curing initiator and a high-temperature-curing initiator, and it also relates to an artificial marble containing a hardened form of the resin syrup, and to a production method for the same. The present invention can provide resin syrup having outstanding curing efficiency and a viscosity suitable for press molding by a process such as maturation because of the inclusion of the high-molecular-weight acrylic material containing a carboxyl group, the room-temperature-curing initiator, and the high-temperature-curing initiator, and it can provide an artificial marble containing a hardened form of the resin syrup, and a production method for the same.

Abstract: The present invention relates to artificial marble including chips of plate-shaped waste glass and a method for fabricating the same. The method includes preparing chips of plate-shaped waste glass having a thickness of 0.6 mm or less and a large diameter of 20 mm or less using thin plate glass as a waste product generated in production of an LCD backlight unit, and adding the chips to a base compound including at least one polymer resin and an additive. The prepared artificial marble has an outer appearance similar to that of natural stone, a surface having excellent properties, and optimum characteristics when used as an interior material for floors, walls, kitchens, and the like.

Abstract: Disclosed herein is a cross bar of a roof carrier for vehicles. The cross bar may include a cross bar body. First and second brackets are provided on both ends of the cross bar body. First and second locking pins are provided, respectively, on the first and second brackets to be elastically ejected. A link is positioned in the first bracket and hinged to the first locking pin. A release lever includes a coupling part hinged to the link and installed via a rotating shaft, and a grip part exposed to the outside, so that when the release lever rotates, the link and the first locking pin are pulled into the cross bar body. A wire couples the coupling part of the release lever with the second locking pin. According to the present invention, the release lever is mounted to only one side and only one wire is used, thus reducing manufacturing costs.

Abstract: Disclosed are artificial marble and a method of manufacturing the same. The artificial marble has a natural aesthetic pattern like a flowing pattern to exhibit an equivalent or superior texture to that of natural marble. Further, as the artificial marble is prepared by placing an uncured marble resin sheet or block in a mold and pressing, the artificial marble has excellent mechanical strength and gloss and does not contain bubbles therein even after pressing at a low temperature and a low pressure.

Abstract: The present invention relates to an artificial chip having the texture of natural granite that includes 80 to 95 parts by weight of a core part and 5 to 20 parts by weight of a base resin, and an artificial marble including the same. According to the present invention, different colors and different sizes of cores are included in the artificial chip, and thus various colors can be simultaneously expressed in one chip, thereby preparing an artificial marble with the texture of natural granite.

Abstract: Provided are a resin composition, comprising 100 parts by weight of a styrene-methylmethacrylate resin solution containing a styrene-methylmethacrylate copolymer and at least one of styrene and methylmethacrylate; 100 to 200 parts by weight of an inorganic filler; and 0.5 to 10 parts by weight of a cross-linkable monomer; and an artificial marble prepared using the same and a process for preparing the same. The resin composition can provide an artificial marble having improved transparency due to reduction of refractive index difference between aluminum hydroxide and methylmethacrylate while maintaining excellent weatherability and thermal characteristics possessed by a conventional acrylic polymer.
