Antifreeze fluid for automobile engine

Abstract

The invention provides an antifreeze fluid for an automobile engine, which is prepared from the following raw materials in parts by weight: 15-30 parts of ethylene glycol, 8-12 parts of glycerol, 1-5 parts of methyl silicone oil, 0.03-0.05 part of sodium stannate, 1-3 parts of potassium hydroxide and 30-50 parts of water. The preparation method of the antifreeze fluid comprises the steps of: placing the ingredients of all the raw materials into a reaction kettle according to a formula ratio, stirring and mixing the ingredients uniformly, and removing impurities by using a filter, so as to obtain the antifreeze fluid. The antifreeze fluid for the automobile engine, which is provided by the invention, is stable in performance and difficult to volatilize, does not precipitate, and has the effects of low temperature resistance, rust resistance, corrosion resistance, moderate price, low toxicity, no abnormal odor, good anti-freezing effect and prolongation of the service life of the engine.

Description

technical field [0001] The invention relates to the technical field of antifreeze, in particular to an antifreeze for automobile engines. Background technique [0002] With the improvement of people's living standards, automobiles, diesel vehicles and other motorized equipment have become an indispensable means of transportation in people's daily life. The main power equipment - the engine, especially the water-cooled engine, in the environment of winter or low temperature Among them, the cooling system is prone to freezing or freezing. In order to make the car continue to be used at low temperatures in winter, some substances that can lower the freezing point of water are added to the engine coolant as antifreeze. [0003] Antifreeze is the cooling medium of the internal combustion engine circulating cooling system. It has excellent performances such as antifreezing in winter, anti-boiling in summer, anti-scaling and anti-corrosion throughout the year, and has little or no ...
