Preparation method of high-fog and high-permeability TV light diffusion agent

The invention provides a preparation method of a high-fog and high-permeability TV light diffusion agent. The preparation method comprises the following steps: adding the following components in percentage by mass: 3 to 4 percent of a TV light diffusion functional material, 3 to 5 percent of titanium dioxide, 14 to 20 percent of spherical organic silicon particles with the grain diameter of 1.6 to1.8mu m and 3 to 5 percent of a paraffin wax light diffusion agent, and mixing; pre-dispersing by utilizing a small-size high-speed stirrer; stirring for about 5min; mixing stirred materials with polystyrene with the mass percent of 68 to 75 percent; putting a mixture into the high-speed stirrer and mixing and stirring for about 10min; controlling the material temperature to be 60 to 70 DEG C; after mixing and stirring, adding a mixture into a double-screw granulator and granulating, wherein the molding temperature is 180 to 220 DEG C. By adopting the TV light diffusion agent produced by thepreparation method provide
