Problems solved by technology

[0004] However, when the above-mentioned prepared daylighting panels are used in building facilities to complete the process of introducing sunlight from outdoors to indoors, the daylighting panels can only block ultraviolet rays in specific bands or small-range bands. Unsaturated resin, the main raw material, has great damage, mainly manifested in: yellowing, hardening, cracking, pulverization, glass fiber leakage, plate perforation, water leakage, and short service life of the lighting plate.
[0005] Technicians can block ultraviolet rays by applying gel coat coating to the existing daylighting board, which can completely block ultravio

Abstract

The invention provides an ultraviolet resistant material, comprising the following components of 55 wt%-60 wt% of an unsaturated resin, 25 wt%-30 wt% of glass fibers, 0.8 wt%-2 wt% of a curing agent; 0.5 wt%-2 wt% of a promoter and 0.1 wt%-8 wt% of an ultraviolet blocking agent, wherein total sum of the components is 100%; and the ultraviolet blocking agent is one or more of a salicylate compound, a phenyl ketone compound, a benzotriazole compound, a substituted acrylonitrile compound, a triazine compound and a hindered amine compound. Transmittance of the lighting board prepared by the method for full-band ultraviolet ray is 0 and the lighting board has good light transmission.

Description

technical field [0001] The invention belongs to the technical field of lighting panels, and in particular relates to an anti-ultraviolet material, a lighting panel and a preparation method of the lighting panel. Background technique [0002] Daylighting panels, commonly known as glass fiber reinforced plastics, have good lighting properties to improve building lighting effects, and have good impact resistance, sound insulation and energy saving properties, so they are widely used in industrial plants, large supermarkets, libraries, etc. that require good lighting Sexual building facilities. [0003] At present, the lighting panels on the market are mainly made of unsaturated resin as the base material, and are prepared by adding accelerators, curing agents, glass fibers and other additives. The specific preparation method is: mix unsaturated resin, accelerator and curing agent to obtain a resin mixture, coat the resin mixture on the lower carrier film, correct the thickness...
