Problems solved by technology

[0002] The temperature is low in winter. In order to make the car continue to be used at low temperature in winter, the engine coolant needs to add some substances that can lower the freezing point of water as antifreeze to keep the cooling system from freezing in low temperature weather and operate normally. However, the existing Antifreeze for locomotives, the effect is not ideal, and the production cost is high

Abstract

A disclosed locomotive antifreeze fluid is composed of the following raw materials in parts by weight: 40-55 parts of diethylene glycol dimethyl ether, 3-5 parts of sodium benzoate, 2-7 parts of sodium silicate, 3-8 parts of borax, 0.1-0.5 part of sodium phosphate, 0.5-0.9 part of brown sugar, 0.1-0.4 part of toluidine, 0.1-0.3 part of a scale and corrosion inhibitor, 0.1-0.3 part of an anti-oxidant, and 40-50 parts of distilled water. The locomotive antifreeze fluid is excellent in stability and uneasy to volatize, does not obstruct pipelines, is high in antifreeze, antirust and antifouling properties, good in usage effect and low in product cost.

Description

technical field [0001] The invention relates to a locomotive antifreeze. Background technique [0002] The temperature is low in winter. In order to make the car continue to be used at low temperature in winter, the engine coolant needs to add some substances that can lower the freezing point of water as antifreeze to keep the cooling system from freezing in low temperature weather and operate normally. However, the existing Antifreeze fluid for locomotives has unsatisfactory effect and high production cost. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides a locomotive antifreeze. [0004] The technical scheme of the present invention is: a kind of locomotive antifreeze, is made up of the raw material of following parts by weight: 40-55 parts of diethylene glycol methyl ether, 3-5 parts of sodium benzoate, 2-7 parts of sodium silicate, 3-3 parts of borax 8 parts, sodium phosphate 0.1-0.5 parts, brown sugar 0.5-0.9 par...
