Embodiment 1

[0048] A long-acting antifreeze for automobiles, which is composed of the following parts by weight: 50 parts by weight of ethylene glycol, 50 parts by weight of distilled water, 0.1 parts by weight of borax, 0.1 parts by weight of phosphate trisalt, and 0.3 parts by weight of sodium benzoate; 0.05 parts by weight of azole, 0.2 parts by weight of triethanolamine, 0.1 parts by weight of coloring agent, and 0.05 parts by weight of defoamer.

[0049] Preparation:

[0050] Add distilled water and ethylene glycol into the stirred tank at a weight ratio of 1:1, stir for 10 minutes, add the remaining material from the stirred tank, take it out, heat to fully melt, add it to the stirred tank, and continue to stir for 40 minutes. Filtration, filling and discharging.

[0051] The performance of the automobile long-lasting antifreeze prepared in this embodiment is tested. The main test items are: density, freezing point, pH, boiling point, ash, aluminum pump cavitation corrosion, cast aluminum...

Abstract

The invention provides a long-acting antifreezing solution for an automobile. The long-acting antifreezing solution is prepared from, by weight, 30-60 parts of ethylene glycol, 40-60 parts of distilled water, 0.1-0.2 part of borax, 0.1-0.2 part of trivalent phosphate, 0.1-0.3 part of sodium benzoate, 0.05-0.1 part of benzotriazole, 0.1-0.2 part of triethanolamine, 0.001-0.1 part of a coloring agent and 0.01-0.05 part of an antifoaming agent. Ethylene glycol is adopted as a raw material, and the high stability of the long-acting antifreezing solution for the automobile is guaranteed. A preservative, a rust remover, the antifoaming agent, a pH value adjusting agent and the like are reasonably matched, and the corrosivity of the long-acting antifreezing solution to automobile metal is effectively relieved. Compared with the prior art, the long-acting antifreezing solution has multifunctional purposes, is lower in freezing point and more stable, and cannot corrode copper, iron, aluminum, tin, cast iron and other automobile metal accessories.

Description

Technical field [0001] The invention relates to the technical field of antifreeze liquid, in particular to a long-lasting antifreeze liquid for automobiles. Background technique [0002] The full name of antifreeze liquid is antifreeze coolant, which can prevent the coolant from freezing and bursting radiator and freezing damage to the engine cylinder block or cover when parking in cold winter. In normal car maintenance items, the engine antifreeze needs to be replaced every year after driving. In winter, the coal and mineral powder transported by railways and roads are easy to freeze in the car, which brings great difficulties to transportation and unloading. This not only causes great economic losses to railways, ports and coal users, but also Brings safety risks. [0003] Coolant is mainly used in automobile engine cooling system, which has the functions of cooling, anti-freezing, anti-scaling, anti-corrosion and anti-boiling. The coolant is mainly composed of antifreeze, wat...
