Description
Technical field
The present invention relates to Antifreezing/Cooling Fluids for Automotives field, be specifically related to a kind of vaporization prevention type anti-freeze cooling liquid and preparation method thereof.
Background technology
The anti-freeze cooling liquid that enterprise produces both at home and abroad is at present generally ethylene glycol and water adds some additives again, in engine normally uses, because the temperature of engine is more than 80 DEG C, so the water in deicing fluid can slowly evaporate, if can not make up water in time, then may form potential safety hazard, therefore need frequent moisturizing, bring certain trouble to user.
Summary of the invention
The object of the invention is for above-mentioned technical problem, a kind of vaporization prevention type anti-freeze cooling liquid is provided, and its preparation method is provided.
The technical scheme that the present invention takes:
A kind of vaporization prevention type anti-freeze cooling liquid, it comprises following component: glycerol: 50-60%, water: 30-40%, sodium tetraborate: 1-2%, Sodium Nitrite: 1-2%, sodium hydroxide: 0.1-0.3%, benzotriazole: 0.07-0.1%, Sodium hexametaphosphate 99: 0.1-0.2%, water glass: 0.2-0.5%, ﹣ 50# solar oil or SN5W-30 machine oil: 4-5%, methyl alcohol or ethanol 0.08-1%; Above per-cent is mass percent.
The preparation method of vaporization prevention type anti-freeze cooling liquid of the present invention, its concrete steps are as follows: first water is put into container, add after Sodium hexametaphosphate 99 being dissolved with the hot water of 60 DEG C in the water in container and stir, add sodium tetraborate again, Sodium Nitrite, sodium hydroxide, water glass, with methyl alcohol or ethanol, benzotriazole dissolving is added container, add glycerol again, after above composition is stirred, add ﹣ 50# solar oil or SN5W-30 machine oil, stir while adding, after adding completely, with dispersion machine after 400 turns/min disperses 30 minutes, filtration limit, limit is filling.
Positively effect of the present invention is as follows:
The manufacturer of domestic deicing fluid generally adopts the industrial chemicals such as borate, nitrate, molybdate, phosphoric acid salt, silicate as the sanitas, rust-preventive agent, Scale inhibitors, inhibitor etc. of engine coolant, does not generally do vaporization prevention process.Because there is no vaporization prevention catalogue in the middle of national standard, although the deicing fluid of above material produce can reach GB standard, do not possess vaporization prevention function.The invention solves user in the worry using the engine coolant evaporation run in cooling fluid.
The present invention passes through lot of experiments, comprehensive considering various effects, successively test many kinds of substance, thousands of experiments are carried out, finally determine the anti-freeze cooling liquid formula containing-50# solar oil or SN5W-30 machine oil, this formula effectively can reduce the steam output of anti-freeze cooling liquid, and all the other indexs also meet the regulation of concerned countries standard, other performance perameters of anti-freeze cooling liquid can not be affected while vaporization prevention, damage can not be caused to engine.
