A petroleum coke-containing roof coating composition and a method of treating a building surface using the petroleum coke-containing roof coating composition are also disclosed.

A quantum-dot light conversion film, a preparation method and an application thereof and an anti-ultraviolet blue-free yellow light for chip manufacturing are provided. The preparation method includes: (1) mixing a quantum-dot concentrate with an acrylic monomer, then adding high polymer for secondary mixing, to obtain a polymer; (2) after mixing the polymer and nanoparticles, adding additives for dispersion to obtain a light conversion liquid resin; and (3) coating and curing the light conversion liquid resin to obtain a quantum-dot light conversion film. The light conversion film has high light conversion efficiency, adjustable emission peak position and narrow half peak width. Its surface forms a tightly arranged high refractive index microlens structure. When the light reaches the microlens array, as the light output surface is a lens structure and the refractive index is improved, more light is emitted in the positive direction, thereby effectively improving the light output rate.
