Abstract

The invention discloses environment-friendly anti-freezing fluid for an automobile. The anti-freezing fluid is prepared from the following ingredients in parts by weight: 3-5 parts of benzotriazole, 60-80 parts of diethylene glycol-methyl ether, 2-3 parts of calcium formate, 0.1-0.5 part of fulvic acid, 0.3-0.5 part of isopropyl nitrate, 20-30 parts of sodium nitrate, 0.1-0.5 part of sodium phosphate, 0.3-0.5 part of polysorbate and 20-30 parts of distilled water. The anti-freezing fluid is reasonable in formula, good in use effect and low in production cost.

Description

technical field [0001] The invention relates to an automobile environment-friendly antifreeze liquid. Background technique [0002] The existing locomotive antifreeze has unsatisfactory effect and high production cost. There are two main points to measure the pros and cons of antifreeze: the first is the antifreeze effect, the freezing point of water is 0 ℃, the general antifreeze can reach -40 ℃, and the high-quality antifreeze should be able to reach -60 ℃, which is an important indicator for calibrating the quality of antifreeze; the other is the boiling point of antifreeze, the boiling point of water is 100 ℃, and the antifreeze should be at least above 108 ℃, that is to say, the lower the freezing point, the higher the boiling point. The greater the temperature difference, the better the quality of the antifreeze. 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...
