It is known as the "blood" of the car. The engine oil is composed of two parts: base oil and additives. The base oil is the main component of the lubricant and determines the basic properties of the lubricant. The additive can make up for and improve the deficiencies in the performance of the base oil and give it some new properties. It is an important component of the lubricant. The use of lubricating oil can delay and repair the wear of the engine and protect the engine;

[0003] However, the replacement of engine lubricating oil currently in use is determined based on mileage and time, and the duration of performance degradation of the engine lubricating oil is not determined based on actual usage, resulting in inaccurate oil replacement time and waste. Summary of the invention

[0005] To achieve the above object, the present invention provides the following technical solution: a method for preparing energy-saving repair engine lubricating oil, comprising the following preparation steps:

[0006] S1. First, measure a certain amount of base oil, heat it to a certain temperature, measure the additive, mix and stir to obtain a first mixture;

[0007] S2, continue to add raw materials to the first mixture to prepare lubricating oil and store it;

[0008] S3. Take samples of lubricating oil, save them, and number and manage them;

[0009] S4. Take samples for performance testing and simulate the use of engine lubricating oil;

[0010] S5. Obtain usage data, record it, upload it for later storage, seal it and manage it;

[0011] S6. Regularly test the performance of the engine lubricating oil, predict its service life and record it.

[0012] According to the above technical scheme, the lubricating oil includes the following formula: Qidun RXF-24126 additive, T-304 dibutyl phosphite additive, T-115B sulfurized alkyl phenol calcium, T-107 overbased synthetic magnesium sulfonate, T-701 synthetic barium sulfonate, T-501 di-tert-butyl-p-cresol, T-203 dioctyl basic zinc salt of sulfur and phosphorus, and base oil;

[0013] According to the above technical solution, the raw material formula is as follows: Raw materials by weight percentage:

[0014] Qidun RXF-24126 additive: 5%;

[0015] T-304 dibutyl phosphite additive: 0.8%;

[0016] T-115B Calcium alkylphenol sulfate: 0.2%;

[0018] T-701 synthetic barium sulfonate: 0.05%;

[0019] T-501 di-tert-butyl-p-cresol: 0.1%;

[0020] T-203 bis(octyl)thiophosphorus basic zinc salt: 2%;

[0021] The balance is base oil.

[0022] According to the above technical solution, the base oil in S1 is added into the reactor, and then heated to 60-80 degrees, with a rotation speed of 200-300r / min and rotated for 2-3h.

[0023] According to the above technical solution, the lubricating oil in S2 is sealed and stored, and each time the lubricating oil is extracted, classified and stored.

[0024] According to the above technical solution, in S4, the performance test of the engine lubricating oil includes viscosity R1, flash point R2, high temperature detergency R3, oxidation stability R4 and anti-friction R5;

[0025] The prepared engine lubricant is subjected to an initial performance test before simulated use, with the time being recorded as t0, and each performance test being recorded as 100%. Then, the use environment is set, the engine lubricant is added to the engine for simulated use, the time node is set, the performance of the lubricant is tested and recorded, and the performance test data is expressed as a percentage. Based on the performance test data, the comprehensive performance value is calculated, the performance attenuation is analyzed, and finally, the time for the engine lubricant to attenuate to a certain value is calculated and predicted, so as to grasp the service life of the engine lubricant;

[0026] Take t1, t2, t3... as time nodes respectively, the intervals between adjacent time nodes are equal, and the adjacent time nodes are divided into four parts to simulate the usage environment of four seasons;

[0033] R 综合j =a(t j )b

[0034] Wherein, a and b are both real numbers, and b<0;

[0035] The test data of engine oil performance is ≥ 6 groups. Take the last 3 groups and calculate the values ​​of a and b in pairs. Then calculate the arithmetic mean of a and b respectively and substitute them into the following formula to select a constant value R of engine lubricating oil. 预设 , the time it takes to decay to this fixed value is calculated by the following formula;

[0036]

[0037] in, represents the mean of a;

[0038] represents the mean of b;

[0040] |t| is the time difference between adjacent time nodes;

[0041] Substitute the known data and find the value of n, which means that at the nth time node, the oil performance decays to R 预设 .

[0042] According to the above technical solution, the use environment includes temperature c, engine running speed v, air humidity s and light l;

[0043] Among them, in the temperature environment c, 25℃ is taken as the normal temperature environment, the c value is 0.5, and the c value decreases by 0.01 for every 1℃ decrease until the value is 0, and the c value increases by 0.01 for every 1℃ increase until the temperature environment c value is 1;

[0044] In the engine running speed v, 2500r / min is taken as the normal running speed of the engine, the v value is 0.5, and the v value decreases by 0.01 for every 50r / min decrease until the value is 0, and increases by 0.01 for every 50r / min increase until the value is 1;

[0045] In the air humidity s, 50% is taken as the general humidity, the s value is 0.5, and the s value decreases by 0.01 for every 1% decrease until it reaches 0, and increases by 0.01 for every 1% increase until it reaches 1;

[0046] In the light l, 10000lx is taken as the general light, the l value is 0.5, and the l value decreases by 0.01 for every 200lx decrease, until the value is 0, and increases by 0.01 for every 200lx increase, until the value is 1.

[0047] According to the above technical solution, a lubricating oil is prepared according to the method for preparing an energy-saving repairable engine lubricating oil as described in the right.

[0048] Compared with the prior art, the present invention has the following beneficial effects:

[0049] 1. By setting the engine lubricant to be used in the actual use environment, simulating the use, and regularly recording the engine lubricant performance, calculating the comprehensive performance, and then setting the comprehensive performance, the use time is predicted. It is possible to more accurately predict the use time when the performance decays to a certain level based on actual use, make a more accurate prediction of the use time, obtain more accurate usage conditions, provide a reference for subsequent engine lubricant replacement, and reduce the waste caused by blind replacement of engine lubricants.

[0050] 2. By recording the performance of the engine lubricant during use, determining the performance degradation and calculating the comprehensive performance, we can comprehensively understand the performance of the engine lubricant during use, study the relationship between performance degradation and time, and better study the performance of the engine lubricant.

[0051] 3. When testing the performance of the engine lubricant, set the same time interval to record the performance, and divide the time interval into four parts. Set the use environment for each part to simulate the use environment of the four seasons. This will more accurately simulate the use environment of the engine lubricant, making it closer to the actual use environment and making the recorded data more accurate.

[0052] To summarize, by preparing engine lubricating oil and testing the performance of the engine lubricating oil in time, and then simulating the use of the engine lubricating oil in different environments, it is closer to the actual use environment, regularly testing the performance of the engine lubricating oil, and studying the relationship between the performance decay of the engine lubricating oil and time. Then, the performance of a certain engine lubricating oil is preset, and the time it takes to decay to that performance is determined. This makes it easier to understand the performance and duration of engine lubricating oil replacement, and replace the engine lubricating oil at a more reasonable time.
