Abstract
The invention discloses a high-temperature-resistant anticorrosive paint. The paint comprises a base material, a color filler, an auxiliary agent, a solvent and a curing agent, wherein the base material is prepared by mixing E-44 type epoxy resin and 665 type organic silicone resin in a mass ratio of 1 to 3, adding a coupling agent KH-560 which accounts for 2 to 3 mass percent of the resin system, adding dibutyltin dilaurate serving as a catalyst which accounts for 1 to 2 mass percent of the coupling agent and performing constant temperature reaction at the temperature of between 120 and 130 DEG C for 6 hours; and the mass ratio of the base material to the color filler to the auxiliary gent to the solvent to the curing agent is 100:120-180:3-10:2-20:10-30. The paint can be quickly cured at the normal temperature and has a heat-resistant temperature of 700 DEG C, high hot and cold alternation performance and high corrosion resistance; and a cured coating is not changed after being corroded for 60 days in salt water. The paint remains perfect in corrosion environment such as simulated seawater, acid water and alkaline water. The paint can be widely applied to the fields of chemical industry, power and energy and military and has broad application prospect and economic benefit.
