The invention relates to low-temperature fast-curing epoxide powder paint which comprises the following components in percentage by weight: 45-65% of epoxy resin, 1-5% of polyepoxy active crosslinking agent, 8-18% of curing agent, 0.1-0.5% of curing accelerating agent, 4-30% of precipitated barium sulfate, 4-8% of mica powder, 2-5% of titanium white, 0.5-1.0% of adhesion accelerating agent and assistants. According to the invention, the epoxide powder paint uses a blended resin system of high molecular weight bisphenol A type epoxy resin and novolac epoxy resin; and after being cured by the curing agent, an obtained paint film has the advantages of the epoxy resin such as high adhesion and good alkali resistance and the characteristics of the novolac resin such as favorable water resistance, solvent resistance and acid resistance, and the paint film has favorable heat resistance. Thus, the epoxide powder paint provided by the invention can be adapted to a high-temperature severe-corrosion environment and has favorable market application prospects.
