Publication number: 20080221252Abstract: Disclosed is a rubber composition for tires. The rubber composition for tires comprises polymer having reactive functional group (1) in a rubber raw material, and reactive layered silicate having reactive functional group (2) potentially reacting with the above polymer. When a rubber is manufactured by melt-admixing the rubber raw material that contains the polymer having the reactive functional group (1) potentially reacting with the reactive functional group (2) of the reactive layered silicate, the rubber composition for tires of the present invention exhibits improved compatibility between the rubber raw material and the reactive layered silicate by chemical reaction of the polymer having the reactive functional group (1) contained in the rubber raw material, with the reactive functional group (2) of the reactive layered silicate. By the chemical reaction, the reaction material produced has ionic group and is placed more stably between layers and/or particles of the layered silicate.Type: ApplicationFiled: March 3, 2008Publication date: September 11, 2008Inventor: Han-Seok Song

Patent number: 7365144Abstract: Disclosed herein is a polypropylene composite composition. The polypropylene composite composition comprises 50 to 80% by weight of polypropylene, 6 to 30% by weight of talc, 10 to 30% by weight of a rubber, 3 to 15% by weight of glass bubbles, and 0.5 to 7% by weight of maleic anhydride polypropylene (MAH-PP). According to the composition, the compatibility between the glass bubbles and the polypropylene can be improved, thus enabling effective use of the glass bubbles. Therefore, when the composition is used to produce automotive components, such as automotive interior components, the fuel efficiency of automobiles can be improved due to weight reduction effects of polypropylene composites. In addition, since the composition uses colorless and odorless glass bubbles, it can remove an unpleasant smell generated from conventional interior components using talc and is thus environmentally friendly.Type: GrantFiled: September 15, 2006Date of Patent: April 29, 2008Assignees: Hyundai Mobis Co., Ltd., GS Caltex CorporationInventors: Suk Sun Ka, Myoung Seok Kim, Han Seok Song

Publication number: 20070190198Abstract: Disclosed herein is an apparatus for processing a polypropylene compound containing glass bubbles. The processing apparatus includes an extruder receiving a screw therein, a first hopper mounted on an outer peripheral surface of the extruder at a position corresponding to a beginning portion of the screw and used to introduce the polypropylene compound, which is a main material, into the extruder, and a second hopper mounted on the outer peripheral surface of the extruder at a position spaced apart from the first hopper by a predetermined distance and used to introduce glass bubbles into the extruder, so as to allow the glass bubbles to be mixed with the polypropylene compound that is being transferred by the screw. The processing apparatus has the effect of preventing damage to glass bubbles by minimizing a passage distance of the glass bubble along the screw of the extruder, thereby achieving a reduced weight and improved physical properties of a molded article to be discharged from the extruder.Type: ApplicationFiled: August 31, 2006Publication date: August 16, 2007Applicants: HYUNDAI MOBIS CO., LTD., GS Caltex CorporationInventors: Suk Sun Ka, Duk Chul Jeon, Han Seok Song
