POLYPROPYLENE-BASED RESIN COMPOSITION CAPABLE OF PROVIDING A LIGHT DIFFUSING PLATE WITH EXCELLENT LIGHT RESISTANCE, TOTAL LIGHT TRANSMITTANCE, LIGHT DIFFUSION HAZE, AND LIGHT DIFFUSION RATE, THE LIGHT DIFFUSING PLATE COMPRISING THE SAME, AND A MANUFACTURING METHOD THEREOF

摘要

PURPOSE: A polypropylene-based resin composition is provided to provide a light-diffusion plate which has excellent light transmittance, high luminance, impact resistance, and weathering ability without generating yellowing phenomena.;CONSTITUTION: A polypropylene-based resin composition comprises 0.1-10 parts by weight of light diffusion agent based on 100 parts by weight of base resin. The base resin comprises 60-70 weight% of random propylene resin and 30-40 weight% of impact polypropylene resin. The light diffusing agent is one or a mixture of compounds selectee from a calcium carbonate particle, a barium sulfate particle, a titanium oxide particle, an aluminum hydroxide particle, a silica particle, a glass particle, a mica particle, a magnesium oxide particle, a zinc oxide particle, an acryl-based crosslinked particle, a silicon-based crosslinked particle, or a styrene-based crosslinked particle.;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Incident light; (BB) Transmitted light; (CC) Scattered light; (DD) Diffusing agent
