The invention discloses a fiber-reinforced plastic panel for an environment-friendly power distribution cabinet and a production method thereof. The fiber-reinforced plastic panel is made from 35-55 parts of epoxy resin, 20-25 parts of fluororesin, 40-50 parts of reinforcing fiber, 15-25 parts of diatomite, 8-15 parts of polyvinyl butyral, 6-10 parts of cobalt naphthenate styrene, 5-10 parts of cyclohexanone peroxide, 2-4 parts of polyester resin, 4-8 parts of titanium dioxide, 3-9 parts of triethylamine, 4-8 parts of aluminum oxide, 2-4 parts of a dispersant, 1-5 parts of a defoaming agent, 3-6 parts of a plasticizer, 1-5 parts of a stabilizer, and 2-8 parts of a curing agent. The panel produced from the above materials in a scientific ratio is low in density, light in weight, high in hardness, good in toughness and good in electrical insulation, has good fire resistance, corrosion resistance, wear resistance and antistatic property, is time- and labor-efficient to mount, is safe and reliable and enables a longer life for a power cabinet.
