Abstract

The invention discloses a clean anti-freezing solution for automobiles, and belongs to the technical field of anti-freezing solutions. The anti-freezing solution is obtained from reacting the following components in parts by weight: 80-90 parts of propylene glycol, 10-30 parts of deionized water, 2-3 parts of a decarbonizer, 10-20 parts of a corrosion inhibiter, 5-10 parts of silicate, 6-8 parts of a silicate stabilizer, 1-3 parts of a defoamer and 1-5 parts of a colorant, wherein the decarbonizer is prepared from the following raw materials by weight proportion: 90% of deionized water, 5% of triethanolamine, 1% of a surfactant and 4% of a foaming agent; the corrosion inhibiter adopts triethanolamine. The invention also discloses a preparation method of the anti-freezing solution. The clean anti-freezing solution for automobiles provided by the invention can provide long-acting corrosion protection through the homemade decarbonizer, is low in cost, environment-friendly and free of pollution, and avoids gel deposition and scale formation; the preparation method of the clean anti-freezing solution for automobiles is simple and environment-friendly in steps and easy to operate.

Description

technical field [0001] The invention belongs to the technical field of antifreeze, and in particular relates to a clean automobile antifreeze and a preparation method thereof. Background technique [0002] The full name of antifreeze should be called antifreeze coolant, which means coolant with antifreeze function. [0003] The cooling medium of the engine circulation cooling system, and the working state of the cooling system directly affects the normal operation and [0004] The service life of the vehicle, antifreeze is not only used in winter, it should be used throughout the year. [0005] The traditional antifreeze process is seriously polluted, and it is very easy to absorb impurities, causing secondary pollution. Contents of the invention [0006] Purpose of the invention: the purpose of the present invention is to provide a kind of clean automobile antifreeze antifreeze, make it clean and pollution-free, and can not produce precipitation and fouling; Another pur...
