Anti-scaling antifreezing fluid and preparation method thereof

Abstract

The invention provides anti-scaling antifreezing fluid and a preparation method thereof, relating to the technical field of antifreezing fluid. The antifreezing fluid comprises the following components in parts by weight: 22-38 parts of ethylene glycol, 6-12 parts of calcium chloride, 1.5-5.5 parts of antiscales, 0.5-1.3 parts of sodium benzoate, 1.8-3.5 parts of triethanolamine, 0.5-1.2 parts of sodium dodecyl benzene sulfonate, 0.2-0.6 part of antifoaming agent and 20-35 parts of distilled water. The preparation method of the anti-scaling antifreezing fluid comprises the steps of weighing, mixing in sequence, ultrasonically stirring and filtering. The anti-scaling antifreezing fluid provided by the invention is alcohol water-based cooling fluid. The boiling point of the antifreezing fluid is increased and the freezing point is reduced through synergy of various substances, so that the anti-scaling antifreezing fluid has better anti-scaling and anti-corrosion properties while achieving better antifreezing property. The antifreezing fluid prepared according to the preparation method provided by the invention has stable quality and can be stored and used for a long term. The preparation method is simple in process and is easy and fast.

Description

technical field [0001] The invention belongs to the technical field of antifreeze, in particular to a scale-inhibiting antifreeze for motor vehicles and a preparation method thereof. Background technique [0002] Antifreeze, that is, antifreeze coolant, is a coolant with antifreeze function. In severe winter or low temperature, it can prevent the coolant from freezing, which will cause damage to the radiator and engine cylinder block, and affect the use of motor vehicles. With the continuous development of antifreeze technology, the traditional antifreeze performance has tended to be stable, and it has been replaced by the further development of antifreeze in cooling performance. [0003] According to the survey, more than 70% of automobile cooling systems have scale and rust, which seriously affects the heat dissipation function of the cooling system. Most car owners think that antifreeze should be used in winter, and tap water can be used in other seasons. Thick scale wi...

Problems solved by technology

It can be seen that the technical solution claimed in this application uses ethylene glycol as the base liquid and adds various substances to improve the antifreeze anti-scaling performance and anti-corrosion performance to a certain extent, but it still cannot achieve high anti-scaling performance. , and the scale inhibition performance is not stable, which is not conducive to long-term use
