Description

technical field [0001] The invention relates to the technical field of FRP gratings, in particular to a modified unsaturated polyester resin FRP grating with high hardness and UV resistance. Background technique [0002] FRP grating is composed of glass felt skeleton and resin coating wrapped outside the skeleton. Because FRP grating is corrosion-resistant and strong in pressure resistance, the application of FRP has developed very fast in recent years. However, in practical applications, the requirements for FRP gratings are slightly different according to different occasions. The hardness and UV resistance of FRP gratings in the prior art cannot meet the requirements of actual use. Contents of the invention [0003] In order to solve the technical problems in the background technology, the present invention proposes a modified unsaturated polyester resin FRP grating with high hardness and UV resistance, which has high hardness and strong UV resistance. [0004] A modifi...
