Embodiment 1

[0013] Mix 48.5g of water, 10g of triethanolamine and aluminate mixture, 35g of ethylene glycol and stir thoroughly. After stirring, add 1g of sodium benzoate, stir to dissolve, then add 5g of silicone oil, stir for 1 hour, and finally add 0.5g of methyl Red, stir well, and finally get a light red low temperature resistant, anticorrosive antifreeze.

Embodiment 2

[0015] Mix 50g of water, 15g of ethylene glycol, 5g of triethanolamine and borate mixture, 10g of methanol, and 10g of diethylene glycol and stir thoroughly. After stirring, add 1g of sodium benzoate and stir to dissolve, then add 8.5g of silicone oil and stir for 1 After hours, add 0.5g methyl blue at last, stir well, and finally get blue low temperature resistant, anticorrosive antifreeze.

Embodiment 3

[0017] 40g of water, 20g of ethylene glycol, 10g of diethylene glycol, 5g of triethanolamine and nitrite mixture, 5g of methanol, 10g of absolute ethanol, mix and stir well, stir well, add 1g of sodium benzoate, stir to dissolve, then add 8.5 g silicone oil, stir for 1 hour, finally add 0.5 g of methyl blue, stir well, and finally obtain a blue low temperature resistant, anticorrosive antifreeze.

Abstract

The invention relates to the technical field of an antifreezing solution. The antifreezing solution is prepared from 30-60% of alcohol, 2-8% of an antifoaming agent, 5-12% of a corrosion inhibitor, 1-3% of sodium benzoate, 0.2-0.4% of a coloring agent and the balance deionized water. The above components are mixed according to the above mass percentages and are stirred fully to form the antifreezing solution with low temperature resistance and corrosion resistance. The antifreezing solution has the characteristics of good anti-corrosive properties, good antifreezing effects, high boiling point and low cost and is suitable for various motor vehicles and mechanical equipment.

Description

Technical field [0001] The invention relates to the technical field of antifreeze, in particular to an antifreeze used for motor equipment, motor vehicles and a preparation method thereof. technical background [0002] The cooling medium of motor equipment and motor vehicle cooling system is generally water as the coolant. Water has the advantages of large specific heat, high latent heat of evaporation and convenient supplementation. However, when the temperature in winter drops below 0℃, the water in the cooling system will turn into ice, which will bring inconvenience to the use of the engine at low temperatures, and may even cause the water tank or cooling system pipes to burst. In order to meet the requirements of the engine to work normally at low temperatures, it is necessary to develop an antifreeze which does not affect the normal use performance of the engine, but also reduces the freezing point. [0003] In recent years, with the development of science and technology, th...
