The fuel economizing crystal is shaped as solid state small slices, the components and the contents (weight percentage) are: docosanol 20 to 30; docosaturated hydroxyacid 30 to 40; octodecyl alcohol 10 to 20; glycol saturated acid amide 3 to 8, glycol methyl ether 3 to 8; methicone 3 to 8, silicon dioxide 5 to 10; and azobenzol 1 to 3; the preparation method is that the above components except silicon dioxide are mixed, heated and agitated, then the mixture is frozen, after being frozen, the mixture is crushed, prilled, and added with the silicon dioxide, and then mould is used to punch the whole mixture into small slice shape. The fuel economizing crystal is convenient for storage and application, when the present invention is added into the fuel oil, the remarkable energy saving and oil economizing effect can be got, and the comprehensive performances are good; at the same time, the manufacturing method is simple and standardized, the operation is easy, the quality of the product can be guaranteed, and the industrialized production can be realized.

Description

Automobile fuel economizing crystal and preparation method

Technical field

The present invention relates to a kind of fuel oil additive that is used for the motor car engine energy-saving and emission-reduction, particularly a kind of fuel economizing crystal of solid tablets shape and preparation method.

Background technology

For making motor car engine save fuel oil consumption, reducing emissions, except improving motor performance, making great efforts to promote fuel qualities, it is fully burnt is the problem that the insider furthers investigate, wherein adding the additive that contains activeconstituents in oil plants such as gasoline, diesel oil, is practicable important channel.Have multiple fuel oil additive at present, have certain fuel-economizing and reduce the effect of discharging, but all be liquid state basically, keeping and use inconvenience.Recently also the someone develops solid-state economizing crystal, but its ingredient, content and preparation method thereof there is no report, and unstable product quality can not realize suitability for industrialized production and applies.The over-all properties of above fuel oil additive and economizing crystal is unsatisfactory, haves much room for improvement.

Summary of the invention

The technical problem to be solved in the present invention provides a kind of and not only takes care of with easy to use, the oil-saving discharging-reducing effect is obvious, and the automobile fuel economizing crystal of good combination property, and provide its preparation method, this economizing crystal component and content science, reasonable, standard, manufacture craft is easy, is convenient to suitability for industrialized production and applies.

Automobile fuel economizing crystal of the present invention is solid-state strip, and its component and content are: behenyl alcohol 20%～30%; 22 saturated alkyd 30%～40%; Stearyl alcohol 10%～20%; Ethylene glycol saturated amide 3%～8%; Ethylene glycol monomethyl ether 3%～8%; Methyl-silicone oil 3%～8%; Silicon-dioxide 5%～10%; Nitrogen benzide 1%～3%, above content all is weight percentage.

The preparation method of above-mentioned automobile fuel economizing crystal operates as follows:

(1) takes by weighing each component by weight percentage respectively: A behenyl alcohol 20%～30%; B 22 saturated alkyd 30%～40%; C stearyl alcohol 10%～20%; D ethylene glycol saturated amide 3%～8%; E ethylene glycol monomethyl ether 3%～8%; F methyl-silicone oil 3%～8%; G silicon-dioxide 5%～10%; H nitrogen benzide 1%～3%;

(2) A, B, C, D, E, F, H component are added in the warming pan, be heated to 150 ℃～250 ℃, and connect stirring 15～20 hours;

(3) above-mentioned compound is put into icebox, under-2 ℃～2 ℃ temperature, after freezing 3～5 hours, take out and pulverize and granulation;

(4) add the G component after the granulation, mix, become strip by die stamping again, every heavy 1～2 gram, and become the plate packing.

This economizing crystal product becomes plate encapsulation as tablet, and general per 25 kilograms of fuel oils add one of this product during use, keeping and use very convenient.This economizing crystal contains 100% activeconstituents, can effectively reduce fuel oil zero pour and viscosity, and cone angle increases when making fuel spray, and burning fully; Fuel oil is reduced in the cylinder wall clinging power, reduce the carbon distribution of cylinder wall, reduce the generation and the discharging of carbon monoxide and other pollutent, can make engine easily start, raise speed soon, quicken strong.This product is to the person poultry harmless, and is harmless to engine and vehicle mechanical, non-secondary pollution.After testing, use this product, energy fuel-economizing 8～20% reduces exhaust gas emission 40～60%, and the oil-saving discharging-reducing effect is obvious, good combination property.Component in this product and content determine that after repetition test raw material is easy to get, and proportioning is scientific and reasonable, its preparation method is simple, no particular requirement, technical process standard, processing ease can guarantee the reliable and stable of quality product, is convenient to realize suitability for industrialized production and large-scale promotion application.
