|Title:||HIGH-TRANSMITTANCE HIGH-HAZE EASY-CLEAN DIFFUSION BOARD AND PREPARATION METHOD THEREOF|
A high-transmittance high-haze easy-clean diffusion board and preparation method thereof. The substrate (1) of the diffusion board is made of transparent polymer material containing light-diffusion particles (2), and single or both sides thereof have a wide-spectrum, antireflection, and easy-clean nano bionic structure (3). In the preparation method, a die plate with a three-dimensional gradient nano structure is used and filled with the same polymer material as that of the substrate. The diffusion board ensures the high mist degree with high transmittance and substantially improves the luminous flux of lamps. Because a cheap die plate method is used for preparation, the process is compatible with the ordinary one for the diffusion board.
