Organosilicon high-temperature resistant coating being solidifiable at normal temperature

The invention provides an organosilicon high-temperature resistant coating being solidifiable at normal temperature, which consists of a component A and a component B, wherein the component A comprises the following components in percentage by mass: 40 to 60 percent of organosilicon resin, 20 to 30 percent of pigment, 5 to 20 percent of filler, 10 to 15 percent of solvent, 0 to 1 percent of antifoaming agent and 0 to 1.5 percent of anti-settling assistant; the component B comprises the following components in percentage by mass: 1 percent of solidifying agent and 99 percent of diluent; and the mass ratio of the component A to the component B is 5-10: 1. The organosilicon high-temperature resistant coating has the characteristics of quick normal temperature drying, tough coating film, cheap price and the like; and when the coating is used together with YJ-2 type inorganic zinc-rich primer and the thickness of the coating film reaches 80mu m, the coat can resist the high temperature of 400 DEG C.
