Embodiment
Below in conjunction with embodiment, the present invention is described in further detail, and following examples are explanation of the invention and the present invention is not limited to following examples.
Embodiment 1:
The present embodiment raw material comprises base oil and additive, and described base oil comprises hydrogenation mineral base oil 650SN and bright stock 150BS; Described additive comprises recombiner H8744B, viscosity index improver OCP, pour point depressant 1-248 and kilfoam T901; In raw material, the mass percent of each component is: hydrogenation mineral base oil 650SN is 72.5%, and bright stock 150BS is 5%, and recombiner H8744B is 13%, viscosity index improver agent OCP is 9%, pour point depressant 1-248 is 0.5%, kilfoam T901 is 0.001%.
Recombiner H8744B of the present invention is the engine oil composite additive of a high-performance multipurpose, its main component is calcium, molybdenum, nitrogen, zinc, it has applied novel ashless dispersant and full calcium base purification agent, there is excellent detergent-dispersant performance energy, effectively reducing carbon distribution generates, splendid oilness and anti-extreme pressure, reduce frictional coefficient and wearing and tearing greatly, reaches splendid energy-saving effect;
The main component of viscosity index improver OCP is ethylene-propylene copolymer, act as increase oil viscosity, improves oil product viscosity temperature characteristic, makes oil product just have good shear stability;
The main component of pour point depressant 1-248 is poly-methyl acrylate, has good pour point depression effect, and low-temperature performance is good, also has the effect that improves viscosity index concurrently simultaneously
The main component of kilfoam T901 is dimethyl silicone oil, act as destruction foam, shortens the time that foam exists.
In the present embodiment, the step of the production technique of engine oil is:
1), under normal temperature, normal pressure, base oil is at the bottom of crude oil storage tank is deposited to crude oil storage tank through precipitation by all kinds of contaminant filters that produce in all kinds of impurity in oily factory production process and transportation;
2) by raw oil pump, the base oil after sedimentation is squeezed into and is in harmonious proportion in still through filtration pump, carry out pulse mediation, be warmed to gradually 65 DEG C simultaneously;
3) additive is added to mediation still, mixed base oil, carries out pulse mediation, and carries out static mixing, then synchronously stir 1 hour,
4) after mediation has been stirred, take out processed oil, the analysis of testing, qualified rear filling.
In the present embodiment, in the harmonic process of lubricating oil, mainly need two kinds of starting material: base oil and additive, base oil and additive become processed oil through being in harmonious proportion, and its production process does not produce the three wastes, and resource utilization is almost 100%.When mediation, first by feedstock pump, base oil is squeezed into and is in harmonious proportion in still, the mode that the metering of base oil can detect by under meter or tank is measured; Again additive is heated to 65 DEG C and pour additive tank into by formula rate, squeezed into and be in harmonious proportion in still by additive pump, if a small amount of additive can directly add and be in harmonious proportion the charging opening of still, after heating pulse stirs, by pump, oil product is delivered in product tank.When filling, by discharge pump, oil product is sent into finished product filling machine and is carried out the packaging of all size.[0018] in the present embodiment, in mediation still, adopt pulse mediation mode, realize by pulse pneumatic mediation system.The principle of work that pulse is in harmonious proportion is: by advanced control system and the gas collection dish that is arranged on Mixer pot bottom, squeeze out airflow with pulse mode, heavier liquor is extruded, run to the air flow of liquid level in the explosion of liquid level nature, powerful bursting force is pushed surrounding to the heavier liquor of releasing at the bottom of tank, heavier liquor is because action of gravity moves downward along surrounding, and tank skin is scraped in punching simultaneously.So go round and begin again from bottom to top, cyclic motion from top to bottom, make base oil component and additive reach abundant mixing.Compared with traditional mechanical stirring, pulse Blending has the following advantages: 1, save electric energy, heat energy, reduce production costs; 2, reduce mediation and stir the time, enhance productivity; 3, effectively avoid additive sedimentation, it is fully dissolved; 4, shorten oil product warm-up time, reduce the rotten tendency of oil oxidation.
In the present embodiment, the principle of work of static mixer, under pressure, allowing fluid impact flow all kinds panel element in pipeline, increase the velocity slope of fluid telescopic movement or form turbulent flow, is " cut apart-position is moved-again converged " when laminar flow, when turbulent flow, fluid, except above-mentioned three kinds of situations, also can produce violent eddy current in section direction, has very strong shear action in fluid, make fluid further cut apart mixing, be finally mixed to form needed milk sap.The loose degree of best result reaches below 10 microns, is protected by the oil product viscosity temperature characteristic of static mixer technique, and mechanical shearing stability and thermal shear stability are better.
Embodiment 2:
The present invention can adjust the mass percent between each composition according to actual needs, referring to table 1.
The mass percent of the each composition of table 1 other embodiments of the invention
The production technique of the present embodiment is identical with embodiment 1.
Although the present invention with embodiment openly as above; but it is not in order to limit protection scope of the present invention; any technician who is familiar with this technology, not departing from changes all in the spirit and scope of the present invention and retouching, all should belong to protection scope of the present invention.
