Problems solved by technology

The most troublesome thing about using water as a coolant medium is the scale problem. The scale adheres to the metal inner surface of the water tank, water jacket or equipment, making the heat dissipation effect worse and worse, and it is also very difficult to remove.

Embodiment 1

[0020] The components and mass percentages of the hard water-resistant antifreeze coolant composition are:

[0021] Ethylene glycol 43%

[0022] Triazine triaminocaproic acid sodium salt 0.5%

[0023] N-octanoyl glutamate sodium salt 2%

[0024] Copper Aluminum Corrosion Inhibitor 0.3%

[0025] Antifungal agent 0.01%

[0026] Defoamer 0.2%

[0027] Alkali retention agent 3%

[0028] Appropriate amount of fluorescein

[0029] water balance

[0030] Wherein, the pH value of the hard water-resistant antifreeze coolant composition is adjusted between 8.2 and 8.6 by using the alkali retaining agent.

[0031] Example 1 The hard water-resistant antifreeze coolant can reach -25°C without freezing and is safe to use.

Embodiment 2

[0036] Sodium N-octanoyl glutamate 1%

[0037] Copper Aluminum Corrosion Inhibitor 0.1%

[0038] Antifungal agent 0.01%

[0039] Defoamer 0.1%

[0040] Alkali retention agent 2%

[0041] Appropriate amount of fluorescein

[0042] water balance

[0043] Wherein, the pH value of the hard water-resistant antifreeze coolant composition is adjusted between 8.2 and 8.6 by using the alkali retaining agent.

[0044] Example 2 The hard water-resistant antifreeze coolant can reach -40°C without freezing and is safe to use.

Abstract

The invention relates a hard-water-resistant anti-freezing cooling liquid composition, and provides a hard-water-resistant anti-freezing cooling liquid having the anti-boiling and anti-corrosive functions in order to overcome the conventional technical shortages. The hard-water-resistant anti-freezing cooling liquid composition is composed of glycol, sodium triazinyltriaminohexanoate, N-caprylyl sodium glutamate, a copper aluminum corrosion inhibitor, a mildew inhibitor, an antifoaming agent, fluorescein, and water.

Description

technical field [0001] The invention relates to the field of antifreeze coolant, in particular to a hard water-resistant antifreeze coolant composition. Background technique [0002] Antifreeze coolant, which means coolant with antifreeze function, referred to as antifreeze, is used for cooling systems of automobiles, train locomotives, tractors, ships, engines, water tanks and various mechanical equipment, diesel engines, gasoline engines, etc. When the ambient temperature is lower than At zero temperature, the water in the cooling system will turn into ice, and the components or equipment of the cooling system will be in danger of being damaged by expansion and cracking. At this time, the selection of antifreeze coolant can ensure its normal operation at low temperature. The most troublesome thing about using water as a coolant medium is scale. The scale adheres to the metal inner surface of the water tank, water jacket or equipment, making the heat dissipation effect wors...
