Abstract
The invention discloses an engine coolant in a propylene glycol/water system and a preparation method thereof. The engine coolant consists of triazine triamino caproic acid, boric acid, an alkali retaining agent, a sodium metasilicate solution, sodium hydroxide, methyne benzotriazole, propylene glycol, a fluorescein and water. The preparation method includes following steps: (1) under a condition of heating to 80-90 DEG C, performing a reaction to the boric acid and the alkali retaining agent to obtain a transparent solution with stirring maintained; (2) successively adding water, the triazine triamino caproic acid, the sodium metasilicate solution, the sodium hydroxide solution, the methine benzotriazole, the propylene glycol and the fluorescein, stopping stirring and performing filtration to obtain the engine coolant.
Description
Technical field
The present invention relates to anti-freeze cooling liquid field, engine coolant of espespecially a kind of propylene glycol/water system and preparation method thereof
.
Background technology
Engine coolant is the cooling fluid with antifreeze function, and be called for short deicing fluid, deicing fluid can prevent when Cold Winter stops, when envrionment temperature is lower than zero degree, water in cooling system will change ice into, and the scatterer of cooling system can by spalling, and engine cylinder block or lid also can be damaged by frost; Engine coolant has higher boiling point, therefore, is not only suitable for use in winter, is also suitable for using summer.The engine coolant of glycol/water system that what current use was maximum is, the freezing point of the engine coolant of glycol/water system depends on the ratio between glycol/water, and when ethylene glycol volume percent is greater than 70%, freezing point declines on the contrary, there is lower-most point; Toxicity ratio propylene glycol due to ethylene glycol wants large many, and in wastewater treatment process, propylene glycol readily biodegradable, so the engine coolant of propylene glycol/water system causes concern day by day.
Summary of the invention
Engine coolant of a kind of propylene glycol/water system of the present invention and preparation method thereof, it is characterized in that, overcome the deficiency of above-mentioned technology, a kind of spot corrosion and resistance to hard water of aluminium pump cavitation corrosion of can alleviating is provided, and there is the engine coolant of the propylene glycol/water system of biodegradability.
