Abstract

The invention puts forward an anhydrous cooling liquid for engines. The anhydrous cooling liquid is composed of the following components by weight: 10-50% of an AST polymer; 20-70% of propylene glycol; 1-10% of triethanolamine; 0.1-3% of coconut oil diethanolamide; 10-30% of glycerol; 0.05-1% of sodium metasilicate; 0.05-3% of benzotriazole; 0.01-0.3% of sodium borate; 0.01-1% of an organic silicon defoamer; and 0.05-3% of sodium benzoate. The invention also discloses a preparation method of the anhydrous cooling liquid for engines. The anhydrous cooling liquid provided by the invention has the advantages of environmental protection and no toxicity, low freezing point, high boiling point, high ignition point, no scale, fuel oil saving, and good heat conductivity, thereby solving the problems of unhealthiness and no environmental protection in the prior art. In addition, the production process is simple and the cost is low, so that the anhydrous cooling liquid is of great popularization performance.

Description

technical field [0001] The invention relates to an anhydrous cooling liquid, in particular to an anhydrous cooling liquid for cooling an engine, and also discloses a preparation method of the anhydrous cooling liquid. Background technique [0002] Coolant is a complex multi-component system, mainly composed of antifreeze, corrosion inhibitor, defoamer, colorant, antifungal agent and buffer. An excellent coolant should have the functions of heat dissipation, anti-corrosion, anti-freezing, high boiling point, anti-scaling and anti-foaming. Antifreeze as an engine coolant has undergone changes from methanol, ethanol, water, salt water, to glycerin, diethylene glycol, and then to ethylene glycol. With the improvement of people's understanding and the development of technology, most antifreezes have been eliminated due to various reasons, such as methanol and ethanol have low boiling points, high vapor pressure and are flammable; salt water mixtures are prone to rust and crystal...
