Abstract
The invention provides phosphorus-containing lubricating oil. The lubricating oil is prepared from cyclic phosphate polymer and high-viscosity lubrication base oil in a mass ratio of 1:5, wherein the high-viscosity lubrication base oil is mineral base oil or synthetic base oil, and has a technical parameter of a viscosity index VI which is more than or equal to 80 and less than 120. According to the phosphorus-containing lubricating oil, ZDDP is replaced by sodium trimetaphosphate [(NaPO3)3], the toxicity of trimetaphosphate on three-way catalysis is much lower than that of ZDDP, and the volatility of trimetaphosphate is far lower than that of ZDDP, so that the defects of ZDDP can be overcome, and long-acting work of a three-way catalyst can be realized on the premise of ensuring basic functions of the lubricating oil.
Description
Technical field
The present invention relates to technical field of lubricating oil, particularly relate to a kind of phosphorous lubricating oil.
Background technology
Dialkyl disulfides zinc phosphate (ZDDP) is the multipurpose additive of a kind of double antioxidation, anticorrosive, the excellent properties such as resistance to wear, and is indispensable addO-on therapy in IC engine lubricating oil. But, P elements is to the toxic effect of the ternary catalyzing unit on motor vehicles, phosphorous precipitation compound, and especially zinc phosphate can make three-way catalyst lose efficacy and endanger oxygen sensor. The ZDDP problem caused how is overcome to be always up a technical barrier.
Due to the protection of atmospheric environment, the requirement of automotive emission is more and more higher, result in the efficiency of ternary catalyzing unit and must there be clear and definite index in the life-span. Therefore, the phosphorism of lubricating oil causes that the problem making three-element catalytic just shows, due to ZDDP and similar products irreplaceability in lubricating oil at present, it is presently mainly and takes low-phosphorous volatility ZDDP technology, control is realized by reducing the volatility of ZDDP, owing to being not directly dependent upon between lubrication oil volatility and the volatility of ZDDP, the volatility of phosphorus and volatile rule of lubricating oil cannot be found out, be hardly formed that a set of principle is clear, the method for effect stability to be to reduce the volatility of phosphorus, therefore, there is a kind of new lubricating oil to be developed.
Summary of the invention
It is an object of the invention to solve the defect that above-mentioned prior art exists, it is provided that a kind of new lubricating oil.
A kind of phosphorous lubricating oil, is made up of cyclic phosphate polymer and high viscosity lubricating base oil; Wherein, the mass ratio of cyclic phosphate polymer and high viscosity lubricating base oil is 1:5;
Described high viscosity lubricating base oil is mineral base oil or synthetic base oil, and its technical parameter is: viscosity index (VI) VI, 80��VI < 120.
Further, phosphorous lubricating oil as above, described cyclic phosphate polymer is sodium trimetaphosphate micropowder (NaPO3)3;
Sodium trimetaphosphate micropowder (NaPO3)3Technical specification be:
1. content 99.0%;
2. insoluble matter 1%;
3. pH value: 6-9;
4. D50 particle diameter 5000 order
Further, phosphorous lubricating oil as above, described sodium trimetaphosphate micropowder forms through thick level mechanical activation comminution, the pulverizing of one-level high velocity air, two grades of supersonic jet mills.
Further, phosphorous lubricating oil as above, described sodium trimetaphosphate micropowder and high viscosity lubricating base oil are mixed by stirring.
Beneficial effect:
The present invention is with sodium trimetaphosphate [(NaPO3)3] replace ZDDP. Owing to the toxic of three-element catalytic is significantly less than ZDDP by sodium trimetaphosphate, and the volatility of sodium trimetaphosphate is far below ZDDP, and the shortcoming overcoming ZDDP, under the premise ensureing lubricating oil basic function, it is achieved the long-acting work of ternary catalyzing unit.
Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearly, below technical scheme in the present invention be clearly and completely described, it is clear that described embodiment is a part of embodiment of the present invention, rather than whole embodiments. Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
Embodiment:
The present invention provides a kind of phosphorous lubricating oil, and it is by sodium trimetaphosphate (NaPO3)3It is that 1:5 is prepared under mixed at high speed stirs with the mass ratio of high viscosity lubricating base oil.
Wherein, described high viscosity lubricating base oil is mineral base oil or synthetic base oil, and its technical parameter is: viscosity index (VI) VI, 80��VI < 120.
Sodium trimetaphosphate (NaPO3)3Technical specification be:
1. content 99.0%;
2. insoluble matter 1%;
3. pH value: 6-9;
4. particle diameter (surveying D50 order) 5000.
Mean diameter is that in size distribution curve, cumulative distribution is the equivalent diameter of the largest particles when 50%. D90 particle diameter, D50 particle diameter, D10 particle diameter are that in distribution curve, cumulative distribution is the equivalent diameter (mean diameter) of the largest particles when 90%, 50%, 10% respectively
Described sodium trimetaphosphate micropowder is prepared from through three below pulverising step:
1. thick level mechanical activation comminution; 2. one-level high velocity air pulverizes (1��2 Mach); 3. two grades of supersonic jet mills (3��4 Mach)
Last it is noted that above example is only in order to illustrate technical scheme, it is not intended to limit; Although the present invention being described in detail with reference to previous embodiment, it will be understood by those within the art that: the technical scheme described in foregoing embodiments still can be modified by it, or wherein portion of techniques feature is carried out equivalent replacement; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of various embodiments of the present invention technical scheme.
