Rayleigh scattering material master batch, preparation method thereof, obtained light diffusion plate and lighting device

The invention provides a Rayleigh scattering material master batch, a preparation method thereof, an obtained light diffusion plate and a lighting device, and belongs to the technical field of high polymer materials. The Rayleigh scattering material master batch comprises the following components in percentage by mass: 98.28%-99.98% of a transparent polymer, 0.02%-0.8% of nano scattering particles, 0-0.01% of blue toner, 0-0.4% of a lubricant, 0-0.5% of an antioxidant and 0-0.01% of a light stabilizer. The Rayleigh scattering material master batch takes the transparent polymer and the nano scattering particles as main components, and through a matched and optimized preparation process, a board prepared based on the master batch can really simulate a blue sky effect in a natural state when being used for a lighting device, people can enjoy the feeling of sunshine in clear sky in places without sunshine, and physical and mental pleasure of people is promoted. 本发明提出一种瑞利散射材料母粒、其制备方法及所得光扩散板和照明装置，属于高分子材料技术领域。该瑞利散射材
