The antifreezing agent is prepared from the following raw materials in parts by weight: 20-35 parts of polymethacrylate, 10-20 parts of sodium gluconate, 8-17 parts of Fe(C5H5)2, 10-20 parts of polyethylene glycol, 20-30 parts of glycerol, 1-5 parts of polytetrafluoroethylene, and 10-18 parts of alkyl glycoside. The smoke-eliminating antifreezing agent for diesel oil disclosed by the invention can keep continuously supplemental firing, and can significantly reduce the condensation point and cold filter plugging point of diesel oil, prevent the diesel oil from being frozen at low temperature, clean parts, improve the effect of smoke elimination, and reduce the emission of exhaust gas.
Description
Technical field
The present invention relates to technical field of petrochemical industry, particularly a kind of smoke abatement anti-freeze agent for diesel fuel.
Background technology
Diesel oil because its Financial cost is cheap, dynamic property strong, and is widely used in the motor spirit of cargo truck, motorbus, tractor, locomotive, boats and ships and various agricultural, building, mine, military mechanized equipment.But because of mass property own and the high pressure spraying combustion system of diesel oil, the discharge over-emitting black exhaust phenomenon of diesel engine is very serious, how to solve diesel emission this problem seriously polluted and also becomes worldwide heat subject.Diesel oil is the Crystallization Plugging oil circuit because easily forming eutectic under its paraffin molecule of mass property in the winter time low temperature again, has annoying vast diesel oil human consumer since this phenomenon has diesel oil by oneself all the time.Common solution adopts dangerous naked light to bake car measure to alleviate the oil circuit caused due to wax crystal to freeze, do both dangerous like this, ineffective again, even can cause the safety of fire threat to life and property, for dilly, once freeze, then only have and to thaw with hot water and effect is undesirable, and length consuming time, waste energy.
Application number be 200510012758.8 Chinese invention patent disclose a kind of smoke abatement anti-freeze agent for diesel fuel, its component and component proportion are (ratios of weight and number): detergent-dispersant additive 5 ~ 20, oxidation inhibitor 2 ~ 8, alkyl nitrate ester selected 10 ~ 30, ethylene-vinyl acetate 10 ~ 30, be equipped with that high-quality aviation kerosene 20 ~ 40 is in harmonious proportion, it can keep lasting overheavy firing, clean parts, reduce soot emission.But the aviation kerosene used is expensive, and antifreezing effect is not ideal enough.
And the problem existing for diesel pour inhibitor of approximation function is still function singleness at present, addition is large, and product supply refinery is used as pour point depression additive, and human consumer can not directly use.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of smoke abatement anti-freeze agent for diesel fuel, and it can keep lasting overheavy firing, significantly can reduce condensation point and the cold filter clogging temperature of diesel oil, prevents diesel from freezing under low temperature, and clean parts, improve smoke effect, reduce exhaust emissions.
For achieving the above object, the present invention adopts following technical scheme:
A kind of smoke abatement anti-freeze agent for diesel fuel, be made up of the raw material of following weight part:
Tetrafluoroethylene particle diameter of the present invention is 50 ~ 100 nanometers.Tetrafluoroethylene in the present invention as lubricant, lubricant is put between two surface of friction, its shearing resistance is very little, slightly external force, intermolecularly slippage will be produced, like this external friction between two surface of friction is changed into the internal friction between solid lubrication agent molecule, play good lubrication, Castor Oil tube wall and engine wall, reduce bavin oil drag, improve the mobility of diesel oil under low temperature, ensure that diesel oil conveying is carried out smoothly, keep continuing overheavy firing, ensure the normal use of diesel oil, engine fuel 3 ~ 6% can also be saved.
Preferably, tetrafluoroethylene particle diameter of the present invention is 75 nanometers.Research finds, when tetrafluoroethylene particle diameter is 75 nanometers, demonstrates best lubricity.
Preferably, smoke abatement anti-freeze agent for diesel fuel of the present invention, be made up of the raw material of following weight part:
Both containing polarity oxy radical in polymethacrylate molecule of the present invention, again containing side chain non-polar group, there is adsorption, also there is pendant alkyl group and wax molecule cocrystallization at a certain temperature, and make whole molecule and interconnection of paraffin crystalline particles present " branch " shape, wax crystalline substance is scattered on " branch " not easily grow up, thus plays the eutectic effect reducing condensation point effect; Meanwhile can play stop wax crystalline substance to be grown up due to the polar functionalities in its molecule, the condensation point of diesel oil and cold filter clogging temperature are reduced.
In the present invention, Sunmorl N 60S, as complexing agent, has dispersion, suspension function, sedimentary generation can be stoped, keep duct cleaning, if once fouling, Sunmorl N 60S can dissolve and disperse to form throw out, becomes fluidised form and reach scale removal object after making sclerosis.
In the present invention, diamyl iron in described additive, diesel oil fuel calorific value can be made to improve, and flameholding, easily lights a fire, and efficiency of combustion is high, sufficient combustion, thus reduces soot emission, realizes cleaning of off-gas discharge.
Polyoxyethylene glycol and the glycerol of the present invention's use are nontoxic, non-stimulated, have good dispersiveness, can reduce cold filter point of diesel oil and condensation point.Owing to having colloid in diesel oil, easily in engine, form carbon distribution, affect automobile power, increase oil consumption, the alcohols added in the present invention's formula, effectively can reduce gum level, add the cleaning that alcohols is inherently good and thinner, therefore can prevent carbon deposit from generating, increase ignition intensity, increase the tightness into and out of valve.
Alkyl glycoside is synthesized by renewable resources natural fat alcohol and glucose, it is the more comprehensive new non-ionic surfactants of a kind of performance, it has the characteristic of conventional nonionic and anion surfactant concurrently, having high surface, good ecological security and intermiscibility, is internationally recognized first-selection " green " functional surfactant.The long alkyl chain of alkyl glycoside can with the mutual effect of wax crystalline phase, make the two ends of wax crystalline substance have polarity, thus crystal better disperses, effectively can hinder again the growth of wax crystalline substance, the lubricity between crystal can also be added, thus the probability connected between crystal is reduced, effectively reduce condensation point.Alkyl glycoside can play solublization as tensio-active agent in diesel oil system, because tensio-active agent has the association colloid of formation, micelle inner core is non-polar group, skin is polar group, which provides nonpolar all environment to polarity, the organism of various polarity institute can be provided to be suitable for the environment of dissolving.And because the surface tension of nonionogenic tenside is relatively low, so the micella formed is also more, that forms micelle volume and will increase, and the space of energy solubilising is also more, the amount of precipitation of wax crystalline substance is just relatively fewer, makes the filterableness of diesel oil better.
Beneficial effect of the present invention is:
Smoke abatement anti-freeze agent for diesel fuel of the present invention, it can keep lasting overheavy firing, significantly can reduce condensation point and the cold filter clogging temperature of diesel oil, prevents diesel from freezing under low temperature, and clean parts, improve smoke effect, reduce exhaust emissions.Test-results shows, after using smoke abatement anti-freeze agent for diesel fuel of the present invention, the condensation point of diesel oil is down to-40 ~-30, the more existing frostproofer of cold filter clogging temperature reduces by 10 ~ 15 DEG C, reduces by 60 ~ 75% soot emissions, clean environment firendly, storage time can reach a year and a half more than, stablizes not stratified.
