Antifreezing fluid for vehicles

Abstract

The invention discloses an antifreezing fluid for vehicles, which is prepared from the following raw materials in parts by weight: 11-19 parts of ethylene glycol, 1-5 parts of sodium phosphate, 2-6 parts of sodium chloride, 11-14 parts of sodium benzoate, 1-5 parts of potassium nitrate, 6-16 parts of phenol formaldehyde resin, 5-7 parts of borax, 3-6 parts of sodium molybdate, 4-7 parts of trialkylol amine phosphate, 1-5 parts of methyl tert-butyl ether, 2-8 parts of methyl benzotriazole, 5-9 parts of benzotriazole, 5-9 parts of glycine, 4-8 parts of hydroxypropyl methacrylate, 3-7 parts of methyl silicone oil and 20-40 parts of deionized water. The antifreezing fluid for vehicles has the advantages of reasonable formula, stable effect, high antifreezing property, high antirust property and high scaling resistance.

Description

technical field [0001] The invention relates to the technical field of antifreeze, in particular to an antifreeze for vehicles. Background technique [0002] The full name of antifreeze should be called 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 or cover when the vehicle is parked in cold winter. But we have to correct a misunderstanding, antifreeze is not just for winter, it should be used throughout the year. In the normal maintenance items of the car, the engine antifreeze needs to be replaced every year of driving. [0003] There are many types of antifreeze on the market, but most of them have high manufacturing cost, poor stability and poor antifreeze effect, and what's more, there are serious corrosion phenomena, which affect the service life of the engine. Contents of the invention [0004] Aiming at the deficiencies of the pri...
