PURPOSE: An additive composition of a radiator coolant for vehicles is provided to improve engine efficiency and to have interface activation, lubrication, anti-freezing, anti-corrosion, and debubbling functions. CONSTITUTION: An additive composition of a radiator coolant for vehicles includes 60-80 wt% of a liquid 1,2-propanethiol, 15-30 wt% of a 1,2-glycol, 10-20 wt% of a montmorillonite powder, 5-10 wt% of a condensed phosphate, 5-10 wt% of a borax, 10-20 wt% of a sodium silicate, and 5-10 wt% of a potassium silicate. The montmorillonite powder is obtained by oxygen-reduction sintering a montmorillonite which is a mineral material, at 700-1200 °C, and powderizing the montmorillonite to a size of 5 micron or smaller. |
