Antirust agent used for cold-rolling interprocess cold-rolled plate

The invention discloses an antirust agent used for a cold-rolling interprocess cold-rolled plate. The antirust agent comprises the following components in percentages by weight: 1.0%-3.0% of monoethaneamine benzoate, 2.0%-5.0% triethanolamine, 10.0%-30.0% of sustained release agent, 20.0%-30.0% of pH adjusting agent, 0.01%-0.07% of octadecylamine, 2.0%-4.0% glycerol, 2.0%-5.0% of sodium silicate and the balance of water. The antirust agent, provided by the invention, has the following advantages and effects that: the antirust agent is high temperature resistant and durable in anti-rust ability, the experiment shows that the antirust agent is used for preventing rust of the cold-rolled plate under the high-temperature and high-humidity conditions that the temperature is at 50 DEG C and the humidity is more than 95%, the surface of the steel plate has no corrosion after 72 hours, and the antirust agent has the advantages of safety and environmental friendliness, easiness in volatilization and cleaning, and the like.
