THERMOPLASTIC POLYCARBONATE RESIN COMPOSITION AND AUTOMOTIVE HEAD LAMP LIGHT GUIDE MANUFACTURED BY USING THE SAME CAPABLE OF IMPLEMENTING WHITE LIGHT BY USING SPECIFIC AMOUNT OF BLUE DYE

摘要

PURPOSE: A thermoplastic polycarbonate resin composition and automotive head lamp light guide manufactured by using the same are provided to improve heat resistance and light transmittance and to minimize light loss.;CONSTITUTION: A thermoplastic polycarbonate resin composition comprises 0.001-600 ppm of blue dye, 0.01-5 parts by weight of silicon-based light diffuser which has average particle diameter of 1-100 microns, and 0.01-1.0 parts by weight of a luminescence agent which has average particle diameter of 1-100 microns based on 100.0 parts by weight of polycarbonate resin. The polycarbonate resin has average molecular weight of 15,000-35,000. The blue dye comprises one or more pigments or salt selected from anthraquinone based blue dye of 15-50 carbons.;COPYRIGHT KIPO 2012
