Description
Technical field
The present invention relates to the used non-freezing solution technical field of car engine cooling system, particularly a kind of low-temperature-resistant environment-friendly automobile non-freezing solution prescription and non-freezing solution preparation method.
Background technology
Non-freezing solution makes protective liquid also be engine coolant again, is the circulatory mediator that car engine cooling system is used, and utilizes liquid circulation to flow and derives heat, protection normal working of engine.Automobile non-freezing solution also needs to have higher boiling point except containing alap freezing point and additive, can prevent incrustation scale and to various corrosions of metal of cooling system and performance.
At present, producer generally makes the main component of spent glycol as non-freezing solution.But but there is following shortcoming:
1. not low temperature resistant.The ethylene glycol non-freezing solution is inapplicable when surpassing-40 ℃ of low temperature.
2. poisonous, not environmental protection, biological degradability is poor.
3. inflammable, explosive.
4. easily produce vapour lock.
5. lack work-ing life, easily produce precipitation.
In recent years, because ethylene glycol is generally used by producer, make the ethylene glycol price be elevated, make the automobile non-freezing solution product cost of production higher, client is difficult to accept, and has influenced the sale of manufacturer greatly.The less dimethyl sulfoxide (DMSO) of using of existing domestic production automobile non-freezing solution is as its raw materials for production, so the price of dimethyl sulfoxide (DMSO) is not subjected to market clout, it is lower to produce its cost of non-freezing solution with dimethyl sulfoxide (DMSO), is more easily accepted by market.
Summary of the invention
The purpose of this invention is to provide a kind of low-temperature-resistant environment-friendly automobile non-freezing solution.
Technical scheme of the present invention is: a kind of low-temperature-resistant environment-friendly automobile non-freezing solution, form by dimethyl sulfoxide (DMSO), deionized water, trolamine, benzotriazole, sebacic acid, 2-mercaptobenzothiazole sodium, SODIUMNITRATE, sodium hydroxide, water glass, pigment, defoamer.
Low-temperature-resistant environment-friendly automobile non-freezing solution prescription of the present invention is: basic material is dimethyl sulfoxide (DMSO) and deionized water, and weight percent is:
Dimethyl sulfoxide (DMSO) 37～48%
Deionized water 52～63%;
With basic material is 100% quality criteria, and the weight percent percentage composition of other batchings of adding is:
Trolamine 0.8～1%
Benzotriazole 0.1～0.13%
Sebacic acid 0.25～0.35%
2-mercaptobenzothiazole sodium 0.08～0.1%
SODIUMNITRATE 0.1～0.12%
Sodium hydroxide 0.11～0.15%
Water glass 0.1～0.12%
Defoamer 0.004%
Pigment 0.005%.
The preparation method of non-freezing solution of the present invention, step is as follows:
1). in reactor A, add dimethyl sulfoxide (DMSO), add trolamine, benzotriazole, sebacic acid successively, fully stir until whole dissolvings;
2). in reactor B, add deionized water, add 2-mercaptobenzothiazole sodium, sodium hydroxide successively, stirred 15～20 minutes, add SODIUMNITRATE, water glass more successively, fully stirred 15～20 minutes;
3). with the material among the reactor A, squeeze among the reactor B, behind the abundant mixing of two-phase, add defoamer, behind the continuation stirring and evenly mixing, add pigment again, behind the stirring and evenly mixing with pump; Left standstill 15～20 minutes, and promptly became non-freezing solution.
The beneficial effect that non-freezing solution provided by the present invention has is:
1. adopt dimethyl sulfoxide (DMSO) to replace ethylene glycol to produce non-freezing solution, lower temperature resistance is strong.
2. dimethyl sulfoxide (DMSO) is a raw material production with methyl alcohol, and ethylene glycol is petrochemical materials, and the former is save energy greatly, the influence that product can not risen steadily by cost of material.
3. colourless, the odorless of dimethyl sulfoxide (DMSO) is harmless.
4. in the production process, be added with multiple efficient corrosion inhibitor, can suppress all corrosion takes place, various metals to engine-cooling system have extremely strong defencive function, metal protection test is minimum to six kinds of tinsels (steel, cast iron, steel, brass, scolding tin, aluminum casting) corrosion after tested, can prolong engine work-ing life greatly;
5. raw material does not contain Ca
2+, Mg
2+, CO
3 2-, SO
4 2-Deng becoming dirty component, has superior resistance to hard water.
6. additive is nuisanceless organic additive, belongs to Green Product.
The present invention is a kind of low-temperature-resistant environment-friendly automobile non-freezing solution, adopts dimethyl sulfoxide (DMSO) to replace ethylene glycol as the non-freezing solution main production raw material.Dimethyl sulfoxide (DMSO), normal temperature is the transparent liquid of no color or smell down, has high polarity, high boiling point, non-proton, in the miscible characteristic of water, toxicity is extremely low, and Heat stability is good can be dissolved in ethanol, propyl alcohol, most of organism such as benzene and chloroform.Moisture 40% dimethyl sulfoxide (DMSO) is not frozen at-60 ℃, and with water, snow heat release when mixing, be used for automobile, battlebus at the NORTH CHINA severe cold area, can replace water replenish with ice and snow at any time, and the ethylene glycol non-freezing solution be inapplicable above-40 ℃ of low temperature the time.Because dimethyl sulfoxide (DMSO) boiling point height, can mix with arbitrary proportion with water, reach the purpose that reduces freezing point, and specific heat is moderate, this for winter engine as early as possible and to reach the thermal equilibrium working order be favourable.Dimethyl sulfoxide (DMSO) is produced the symptom of a trend that there is production capacity surplus in used material benzenemethanol, uses not only environmental protection of dimethyl sulfoxide (DMSO), and save energy greatly.Dimethyl sulfoxide (DMSO) is very important aprotic polar solvent and important fine chemical product in addition, one to being described as " Dimethyl Sulfoxide ", be called " panacea " abroad, be widely used in many chemical industry fields such as medicine, agricultural chemicals, oil, chemical industry, organic synthesis, electronics, coating, metallurgy, dyestuff and macromolecular material, and some new purposes are being found constantly also.The inferior maple of dimethyl is with the speed increase in every year 17% in the world, and China is the major country of dimethyl sulfoxide (DMSO) products production, and output and industrial scale are only second to France.Raw material resources are abundant, and product price and quality product take advantage, and add that prospect of export is good, and market potential is huge, are the Chemicals that are worth further research and enlarge exploitation.So have vast market prospect as the main material production automobile non-freezing solution with dimethyl sulfoxide (DMSO).
In a word; the present invention's non-freezing solution has excellent lower temperature resistance, energy-conservation and environmental-protecting performance, is the long lifetime cooling fluid, owing to be host with organic acid and non-harmful organic additive; Green Product sheerly, product performance are good, price suits, help the protection of environmental ecology.
