[0003] At present, antifreeze mainly includes water / ethylene glycol type, water / propylene glycol type, and water / glycerol type. Both ethylene glycol and propylene glycol are products of petroleum refining, which are non-renewable energy sources. With the aggravation of the energy crisis, ethylene glycol The supply of alcohol and propylene glycol will decrease, and it is necessary to find new green and renewable raw materials to replace ethylene glycol and propylene glycol for the production of antifreeze, thereby reducing the dependence of petroleum products; therefore, glycerol is a A very good substitute product, glycerin is a by-product of soap, fatty acid and biodiesel production, which can be recycled, but glycerol has a low heat transfer coefficient, which will affect the engine cooling efficiency during engine operation

Abstract
The invention discloses a preparation method of an antifreezing solution. The antifreezing solution is characterized by being prepared from the following components by weight percent: 0 to 35 percent of synthesized glycerinum, 0 to 20 percent of alpha, alpha, alpha minute-trimethyl trimethylene glycol, 0 to 45 percent of N-methyldiethanolamine, 0.1 to 1.5 percent of 2,4,6-tri(caproyl aminomethyl sulfo)-s-triazine, 0.1 to 3.0 percent of cyclohexanehexol phosphate, 0.01 to 0.05 percent of polyether, 0.01 to 1.5 percent of sodium lignosulphonate, 0 to 0.5 percent of red bean pigment, 0 to 0.5 percent of acorn shell brown and the balance of deionized water. The renewable environment-friendly glycerinum is compounded with 0 to 20 percent of alpha, alpha, alpha minute-trimethyl trimethylene glycol and N-methyldiethanolamine to be used as an antifreezing medium, and various additives with excellent performance are used as a corrosion inhibition medium to prepare the novel antifreezing solution with a low ice point and high corrosion inhibition capacity, a corrosion inhibition effect for multiple metals is realized, and the long-term normal operation of a cooling system can be guaranteed.
Description
technical field [0001] The invention relates to the field of chemical industry, in particular to a preparation method of antifreeze. Background technique [0002] The full name of antifreeze is antifreeze coolant, which means coolant with antifreeze function. Antifreeze can prevent the coolant from freezing and bursting the radiator and freezing the engine cylinder block when parking in cold seasons, and can also prevent the engine from working for a long time ( Especially in summer) cause the water tank of the engine to boil; at the same time, the engine and its cooling system are made of metal, including copper, iron, aluminum, steel, and solder. All antifreeze fluids, especially vehicle antifreeze fluids, must have multiple functions such as antifreeze, anti-boiling, anti-corrosion, and anti-scale; antifreeze fluids can also be used in other circulation systems to prevent the circulation system from being Freezing causes the pipes of the circulation system to burst, thus...
