Iron casting release agent and production process thereof

The invention discloses an iron casting release agent and a production process thereof, and belongs to the field of iron casting. The release agent comprises the components in percentage by mass: 0.5to 1 percent of graphite, 0 to 0.5 percent of coke powder, 5 to 10 percent of Guangxi white mud, 2 to 5 percent of sericite, 1 to 2 percent of coal slime and 82 to 90 percent of water. The iron casting release agent has the advantages of high adhesion property, high sintering speed, capability of being ceramic after being sintered, capability of spray-coating in the iron casting process and good spray-coating effect, and has low manufacturing cost and extremely good actual use effect. The production process comprises the steps of preparing materials, slurrying, spray-coating and the like. Themanufacturing efficiency of the release agent is high, the proportion of part of the components can be adjusted according to the actual requirement, the flexibility is high, and the release agent canbe rapidly solidified and s
