The invention discloses a propping agent for a resin coating film and a preparation method thereof. The propping agent comprises an aggregate, a resin, a curing agent and a dispersing agent, wherein the dosage of the resin is 1%-10% of the weight of the aggregate; the dosage of the curing agent is 0.5%-5% of the weight of the aggregate; and the dosage of the dispersing agent is 0.2%-2% of the weight of the aggregate. The propping agent for the resin coating film provided by the invention has the functions of allowing oil gas to smoothly penetrate and preventing water from penetrating through the propping agent, so that the separating effect of oil gas and water is enhanced by the functions and the oil extraction cost is lowered; due to the excellent hydrophobic property of the resin film, the propping agent has excellent water resistance, the anti-breaking capability of the propping agent is increased and the long-term flow-guiding effect is good; a triple film coating technology is adopted by the invention and the calcium stearate is taken as a dispersing agent, so that the quality is greatly increased, the yield is increased to above 80%, the cost is greatly lowered and the production efficiency is increased; and the preparation method provided by the invention is simple, the product yield is high and the breakage rate of the product is obviously reduced.
