Abstract

The invention relates to vehicle antifreeze which comprises the following components in percentage by weight: 30-70 percent of ultrapure water, 18-50 percent of terylene grade glycol, 10-20 percent of industrial glycerin and 2-5 percent of accessories. Because the industrial glycerin is added in the formula of the antifreeze, the rubber denaturation of warm air pipes and the like is reduced, and the service life is prolonged. The addition of the industrial glycerin can reduce corrosions to metals, thereby enhancing the corrosion resistance and improving the boiling point. The antifreeze can be prepared at any freezing point within the range of between minus 15 DEG C and minus 60 DEG C and meet various requirements.

Description

technical field [0001] The present invention relates to an antifreeze fluid, in particular to an antifreeze fluid for motor vehicles with improved cost and heat transfer. Background technique [0002] The quality of antifreeze on the market is uneven, and the price also varies widely. Most of them are not worthy of the name, and the antifreeze that meets the national standard also has some shortcomings. For example, the cooling system of high-power diesel engines (Cummins engines, etc.) has high requirements for heat transfer, and some antifreeze fluids just ignore this point. When in use, due to poor heat transfer, local high temperature and bumping will occur, causing antifreeze to spray out from the water tank, causing unsafe hazards. This phenomenon is more common when parking. Contents of the invention [0003] The object of the present invention is to solve many deficiencies of the existing antifreeze solution, and provide a kind of antifreeze solution for motor veh...
