The invention discloses a steel plate with a low surface treatment epoxy paint coating and a manufacturing method of the steel plate, and belongs to the technical field of manufacturing of corrosion resistant steel plates. The low surface treatment epoxy paint coating of which the thickness is 0.30mm-0.40mm is arranged on the surface of the steel plate, and is formed by curing of low surface treatment epoxy paint which is prepared from the following components in percentage by weight: components A including bisphenol a type epoxy resin, cycloaliphatic epoxy resin, phenol modified liquefied petrolatum resin, xylene, n-butanol, absolute ethyl alcohol, composite zinc phosphate, ultramicro zinc oxide, nanometer silicon dioxide, nanometer titanium dioxide, graphene, sericite powder, a fluorocarbon modified polyacrylate leveling agent, a copolymer dispersing agent containing acidic groups, a hydroxyphenyl benzotriazole UV absorber and a hindered amine light stabilizer, and components B including a modified alicyclic amine curing agent, a cashew nut shell oil modified polyamide curing agent and xylene, wherein the weight proportion of the components A to the components B is 1 to (0.13-0.15). The steel plate is good in UV aging resistant properties.
