TERRAZZO FOR DISPERSION OF STATIC ELECTRICITY

摘要

PURPOSE: Provided is a production method of an inorganic-based terrazzo excellent in dispersion of static electricity, durability and nonflammability by adding carbon fibers and fiber dispersant to conventional terrazzo composition. CONSTITUTION: The terrazzo composition comprises inorganic main materials such as white cement, crushed stone(2-15mm) and marble chip, and 0.05-0.30pts.wt. of pitch and PAN-based carbon fibers with a length of 1-10mm, and 0.1-0.3pts.wt. of fiber dispersant such as hexanediol and neopentyl glycol. The resultant terrazzo has 2.5x10¬4 - 1.0-10¬6ohm of surface-surface resistance and surface-ground resistance.
