Abstract

The invention discloses long-acting anti-freezing fluid for a locomotive engine. The anti-freezing fluid is prepared from the following ingredients in parts by weight: 10-20 parts of ethylene glycol, 0.1-0.5 part of sodium stannate, 10-15 parts of sodium benzoate, 5-10 parts of micro object max, 10-15 parts of adipic acid, 5-18 parts of petroleum resin, 5-10 parts of triethanolamine, 2-3 parts of glacial acetic acid, 0.1-0.5 part of brassin, 0.3-0.5 part of vinyl acetate, 5-10 parts of potassium dihydrogen phosphate and 10-15 parts of distilled water. The anti-freezing fluid for vehicles, disclosed by the invention, has the advantages that the ice point of the anti-freezing fluid can be lowered compared with that in the prior art, and the corrosion to metals is relatively small.

Description

technical field [0001] The invention belongs to the technical field of antifreeze, in particular to a long-acting antifreeze for locomotive engines. Background technique [0002] At present, there are many patent applications for antifreeze in various countries in the world. The main components are ethylene glycol and water, and preservatives, antirust agents, stabilizers, and color dyes are added. The existing vehicle antifreeze can lower the freezing point, but generally Said to be more corrosive to metal. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a long-lasting antifreeze for locomotive engines with simple proportioning, low cost and good corrosion resistance. [0004] In order to solve the above-mentioned technical problems, the technical solution adopted in the present invention is: a long-lasting antifreeze liquid for locomotive engines, consisting of the...
