Abstract

The invention discloses a preparation method of a high-performance motor vehicle antifreeze fluid. The motor vehicle antifreeze fluid is prepared from the following components in part by weight: 70-80 parts of ethylene glycol, 2-6 parts of adipic acid, 2-5 parts of sodium benzoate, 1-4 parts of sodium salicylate, 4-8 parts of crylic acid, 1-5 parts of sodium hydrogen sulfite, 3-6 parts of octoic acid, 5-10 parts of isopropyl alcohol, 2-5 parts of sebacic acid, 5-10 parts of glycerine, 0.5-2 parts of sodium pentachlorophenate, 0.2-1 part of antifoaming agent, 1-4 parts of sodium hexametaphosphate and 50-60 parts of deionized water. The preparation method comprises the following steps: mixing and dissolving ethylene glycol, deionized water and glycerine, adding the other components and fully mixing and dissolving, heating up and preserving heat for 30-45 minutes under the vacuum degree of 0.02-0.05 MPa. The motor vehicle antifreeze fluid has the characteristics of low freezing point, high boiling point and strong anti-corrosion property and can meet the using requirements of the motor vehicles in different conditions.

Description

technical field [0001] The invention belongs to the technical field of preparation of automobile protective articles, and in particular relates to a high-performance automobile antifreeze and a preparation method thereof. Background technique [0002] Antifreeze is also called antifreeze coolant, which means coolant with antifreeze function. Antifreeze can prevent the coolant from freezing when parking in cold seasons, causing the radiator to burst and freezing the engine cylinder block, but antifreeze is not only used in winter , In the normal maintenance items of the car, the engine antifreeze needs to be replaced every year of driving, and the antifreeze of special vehicles should be replaced more frequently. [0003] Antifreeze is a coolant containing special additives, mainly used in liquid-cooled engine cooling systems. Antifreeze has excellent properties such as antifreezing in winter, anti-boiling in summer, anti-scale and anti-corrosion throughout the year. ...
