Provided are a polypropylene resin composition and a diffusion plate for an illumination apparatus or a signboard, which is manufactured by using the same. As a resin composition for the diffusion plate used in the illumination apparatus or the signboard, the polypropylene resin composition uses a polypropylene resin as a base resin, which is cheaper than an existing material, stable against discoloration due to UV, less deformed by heat, excellent in impact resistance, thereby being suitable to be used in the diffusion plate for the illumination apparatus or the signboard. The present invention provides the polypropylene resin composition for diffusion plate used in the illumination apparatus or the signboard, which comprises: 100 parts by weight of a crystalline polypropylene resin having a melting index of 0.1 to 20g/10min (230°C, weight of 2.16 kg); 0.01 to 0.5 parts by weight of an nucleating agent, and 0.1 to 1 part by weight of an antioxidant. The present invention also provides the diffusion plate for the illumination apparatus or the signboard, which is manufactured by using the same. |
