The present invention relates to a polypropylene-based light diffusing plate and a method for manufacturing the same, and more particularly, it is characterized in that it is manufactured by a coextrusion process while including a polypropylene-based base layer and a coating layer having good weather resistance. Accordingly, it relates to a polypolypropylene-based light diffusing plate characterized in that it has excellent light diffusivity and light transmittance and at the same time improves weather resistance. A polypropylene base layer comprising 100 parts by weight of polypropylene (PP) and 0.1 to 10 parts by weight of a light diffusing agent according to the present invention; A coating layer comprising 60 to 95 parts by weight of a polypropylene (PP) resin, 0.1 to 10 parts by weight of a light diffusing agent, 0.01 to 5 parts by weight of a UV blocking agent, and 0.01 to 5 parts by weight of a UV stabilizer; and of the polypropylene base layer There is provided a polypropylene-based light diffusion plate, characterized in that the coating layer is laminated on at least one surface. Accordingly, according to the present invention, there is an effect of providing a light diffusion plate including a polypropylene resin and a light diffusing agent, which is economical, has excellent light transmittance, light diffusivity, light resistance, and has improved weather resistance. |
