Anti-scaling compounded anti-freezing fluid for locomotive

Abstract

The invention discloses anti-scaling compounded anti-freezing fluid for a locomotive. The anti-freezing fluid is prepared from the following ingredients in percentage by weight: 40-70% of glycerol, 0.05-1% of sodium metasilicate, 0.4-2.5% of sodium benzoate, 0.4-2.5% of calcium formate, 0.3-1.5% of fulvic acid, 0.5-3.6% of isopropyl nitrate, 10-15% of silicone, 0.1-0.5% of potassium permanganate, 1-8% of glycerine and the balance of deionized water. The anti-freezing fluid with good stability, disclosed by the invention, has the advantages that a system of a formula without phosphate radicals is adopted; in the formula, molybdate and organic acid cooperate with each other, jointly provide protection for metal and are assisted with sodium nitrate, so as to provide long-term durable metal corrosion resistance; in the formula, the application of a large volume of sebacic acid exerts a good addition effect on the corrosion resistance of the metal.

Description

technical field [0001] The invention relates to an antifreeze fluid, which belongs to the field of chemical industry, in particular to an anti-scaling compound antifreeze fluid for locomotives. Background technique [0002] Antifreeze is a liquid with a low freezing point. The aqueous solution containing a certain amount of ethylene glycol will not freeze at low temperatures. It has good fluidity and can take away a large amount of heat generated by the engine during operation. It can be used all year round. Used in automobile antifreeze water cooling system, it has the advantages of anti-boiling, anti-corrosion, anti-scaling, anti-freezing, and anti-evaporation loss. According to the evaluation of the impact on the environment, the types of antifreeze can be divided into environmentally friendly pure organic acid antifreeze and low-grade inorganic salt antifreeze. Pure organic acid antifreeze is environmentally friendly and easy to biodegrade, but the cost of use is relativ...
