Abstract

The invention relates to the technical field of daylighting panels, and provides an impact-resistant and weather-resistant daylighting panel and a preparation method thereof.The impact-resistant and weather-resistant daylighting panel is prepared from, by weight, 50-70 parts of base material, 4-6 parts of glass fiber, 2-3 parts of silicon dioxide, 2-4 parts of curing agent and 0.5-1 part of accelerant; the base material comprises unsaturated polyester resin, aliphatic polycarbonate and SEBS (styrene-ethylene-butylene-styrene); the unsaturated polyester resin comprises orthophthalic unsaturated polyester resin and isophthalic unsaturated polyester resin. By means of the technical scheme, the problems that in the prior art, a daylighting panel is poor in impact resistance and weather resistance are solved.
