The new-type composite corrosion inhibitor for circulating cooling medium in internalc ombustion engine is prepared through special process. Its components include sodium nitrite, sodium nitrate, sodium meta-silicate, triazonyl benzene, borate and water. The production process is to divide the chemicals into two kinds, A and B, which are separately mixed, rolled mechanically to homogeneous, weighed and packed. The said composite corrosion inhibitor has comprehensive and excellent corrosion inhibiting property.
