Problems solved by technology

[0002] At present, the antifreeze coolant produced by domestic and foreign enterprises is generally ethylene glycol and water with some additives added. During normal use of the engine, because the temperature of the engine is above 80°C, the water in the antifreeze will evaporate slowly. If it cannot be replenished in time If there is no water, it may form a safety hazard, so it is necessary to replenish water frequently, which will bring certain troubles to users

Abstract

The invention discloses an anti-evaporation antifreezing coolant which comprises 50-60% of glycerol, 30-40% of water, 1-2% of sodium borate, 1-2% of sodium nitrate, 0.1-0.3% of sodium hydroxide, 0.07-0.1% of benzotriazole, 0.1-0.2% of sodium hexametaphosphate, 0.2-0.5% of sodium silicate, 4-5% of 50# light diesel oil or SN5W-30 mobile oil and 0.08-1% of methanol or ethanol. The preparation method comprises the following steps: adding the components into a dispersion machine, dispersing at 400 rpm for 30 minutes, filtering and filling. The evaporation amount of the antifreezing coolant can be effectively lowered, and other indexes also conform to the specifications of the national standard; other performance parameters of the antifreezing coolant can not be influenced on the premise of resisting evaporation; and the antifreezing coolant can not damage the engine.

Description

technical field [0001] The invention relates to the field of automobile antifreeze coolant, in particular to an anti-evaporation type antifreeze coolant and a preparation method thereof. Background technique [0002] At present, the antifreeze coolant produced by domestic and foreign enterprises is generally ethylene glycol and water with some additives added.
