Abstract

The purpose of the present invention is to provide an antifreeze fluid containing triethanolamine, which is characterized in that the antifreeze fluid comprises, by weight, the following components: 50-100 parts of glycol, 0.1-1 parts of triethanolamine, 0.1-1 parts of glycine, 50-80 parts of water, 0.1-1 parts of benzotriazole, 0.1-1 parts of dye, and 0.1-1 parts of methyl silicone oil, and the preparation method comprises the following steps: adding glycol into a reaction vessel, adding triethanolamine, glycine, and methyl silicone oil, stirring the materials and mixing well, adding other components at last, fully stirring the materials and mixing well to obtain a product. The invention has the advantages of antifreezing capability, high heat-transfer speed, reduced heat energy loss, saved fuel consumption, and low cost.

Description

technical field [0001] The invention belongs to chemical preparations, in particular to an antifreeze used in the cooling system of an automobile engine. Background technique [0002] In the cold winter, in order to ensure the normal operation of the car's cooling system, the use of antifreeze has become an inevitable choice. In fact, antifreeze has other functions besides antifreeze. These functions are very important to protect the normal operation of the car. If you use tap water or pure water instead of antifreeze that needs to be replaced, it means giving up driving safety. Moreover, antifreeze not only has the function of antifreeze, but also plays a very important role in antirust, anticorrosion, antiscale, antiboiling, etc., and these preventive functions are also indispensable umbrellas for automobiles. At present, the antifreeze coolant with ethylene glycol as the main component used by the automobile engine cooling system is used for the advantages of antifreezi...
