Problems solved by technology

Although there are a wide variety of related products in the automotive engine coolant market, most of them have defects such as short service life, easy scaling or corrosion, easy oxidation, easy foaming, and low boiling point, which cause the heat transfer efficiency of the cooling system to decrease or cool down. The system is damaged, and it also causes the coolant to deteriorate or be volatile
This not only increases the replacement frequency of the coolant, causing economic waste, but also seriously affects the normal operation of the engine and shortens the engine's operating life.

Embodiment 1

[0031] Embodiment 1. Add 68.00 kilograms of deionized water to the blending kettle, then use the feed circulation pump to extract 30.00 kilograms of ethylene glycol in the raw material storage tank into the blending kettle, and start the stirring and rotary circulation process at the same time, then Add 0.80 kg of triethanolamine, 0.05 kg of benzotriazole, 0.30 kg of phosphoric acid, 0.07 kg of borax, 0.40 kg of sodium benzoate, 0.38 kg of sodium hydroxide, appropriate amount of corrosion inhibitor, defoamer and dyeing The agent is circulated, stirred and mixed for 4-10 hours at a temperature of 25°C-60°C, and the product is filtered by a filter press and packaged to become a finished product.

Embodiment 2

[0032] Embodiment 2. Add 30.00 kilograms of deionized water to the blending kettle, then use the feed circulation pump to extract 68.00 kilograms of ethylene glycol in the raw material storage tank into the blending kettle, and start the stirring and rotary circulation process at the same time, then Add 0.10 kg of triethanolamine, 0.12 kg of benzotriazole, 0.70 kg of phosphoric acid, 0.14 kg of borax, 0.84 kg of sodium benzoate, 0.10 kg of sodium hydroxide, appropriate amount of corrosion inhibitor, defoamer and dyeing The agent is circulated, stirred and mixed for 4-10 hours at a temperature of 25°C-60°C. The product is filtered by a filter press and packaged, which is the finished product air for ventilation and oxidation; after a series of post-processing processes such as standing, settling, and filtering , the package is the product.

Embodiment 3

[0033] Embodiment 3. Add 46.92 kilograms of deionized water to the blending kettle, then use the feed circulation pump to extract 49.00 kilograms of ethylene glycol in the raw material storage tank to the blending kettle, and start the stirring and rotary circulation process at the same time, then Add 0.50 kg of triethanolamine, 0.08 kg of benzotriazole, 1.10 kg of phosphoric acid, 0.10 kg of borax, 1.50 kg of sodium benzoate, 0.80 kg of sodium hydroxide, appropriate amount of corrosion inhibitor, defoamer and dyeing The agent is circulated, stirred and mixed for 4-10 hours at a temperature of 25°C-60°C. The product is filtered by a filter press and packaged, which is the finished product air for ventilation and oxidation; after a series of post-processing processes such as standing, settling, and filtering , the package is the product.

Abstract

The invention relates to a composite engine coolant and method for making same, wherein deionized water, ethylene glycol, triethanolamine, phosphoric acid, tinkalite, sodium benzoate, sodium hydroxide, inhibitor, defoaming agent and coloring agent are used as the raw material for mixing reaction at a finite condition. The product can fit for climatic conditions in different regions.

Description

technical field [0001] The invention relates to a fine chemical product, in particular to a compound coolant for automobiles and light engines. Background technique [0002] The cooling system is an important part of the engine used in vehicles. Its function is to properly cool the parts working at high temperature to ensure that the engine can work normally at a suitable temperature. The anti-freeze cooling effect, anti-scaling and anti-corrosion properties of the coolant are the keys to ensure the normal operation of the cooling system. Although there are a wide variety of related products in the automotive engine coolant market, most of them have defects such as short service life, easy scaling or corrosion, easy oxidation, easy foaming, and low boiling point, which cause the heat transfer efficiency of the cooling system to decrease or cool down. The system is damaged, and it also causes the coolant to deteriorate or be volatile. This not only increases the replacement...
