High reserve alkalinity engine cooling liquid

The present invention discloses a high engine coolant reserve alkalinity, tetrasodium ethylene glycol, fatty acids and alkali metal salts, sodium benzoate, methyl benzoate, phosphate, borate decahydrate, methyl benzotrifluoride triazole, tetraethyl orthosilicate, polyethylene glycol, silicone, sodium hydroxide, defoamer and deionized water, engine coolant invention does not contain an amine, phosphate, nitrite, molybdate toxic salts, strong polluting substances, has an excellent protective effect on various metals in the engine coolant system solder, copper, brass, steel, cast iron, aluminum and the like, can effectively prevent corrosion of the interior of the engine system, It does not appear silicate gel or precipitate formation, good anti-foam properties, and remain stable at relatively low concentrations, especially with high reserve alkalinity, reserve alkalinity than 20ml, long time to keep the engine cooling solution in a suitable pH range, especially for long-term use of an automobile engine.
