Description

Technical Field

[0001] The invention relates to the technical field of gear oil, in particular to an energy-saving repairable gear oil and a preparation method thereof. Background Art

[0002] Gear oil is a special lubricant used to reduce wear between gears, extend gear life, and withstand a certain load. Gear oil mainly refers to the lubricant for automobile transmissions and rear axles. It differs from engine oil in terms of usage conditions, composition, and performance. Automobile gear oil is mainly used in gear transmission mechanisms such as steering gears, transmissions, and drive axles. Due to the high surface pressure during gear transmission, gear oil plays an important role in gear lubrication, wear resistance, cooling, heat dissipation, corrosion and rust prevention, washing, and reducing tooth surface impact and noise.

[0003] However, in the actual preparation process of gear oil, due to the lack of functional regulators that can improve the gear oil's anti-wear and friction reduction capabilities, antioxidant capabilities, acid neutralization capabilities, and oil cleaning capabilities during the additive addition process, the gear oil cannot meet the expected performance requirements after preparation, and is prone to accelerate the damage of mechanical gears. Summary of the invention

[0004] The present invention provides an energy-saving and repairable gear oil and a preparation method thereof, which can effectively solve the problem raised in the above background technology that in the actual preparation process of gear oil, due to the lack of functional regulators that can improve the gear oil's anti-wear and friction reduction capabilities, antioxidant capabilities, acid neutralization capabilities and oil cleaning capabilities during the additive addition process, the gear oil cannot meet the expected performance requirements after preparation and is prone to accelerate the damage of mechanical gears.

[0005] To achieve the above object, the present invention provides the following technical solution: an energy-saving repairable gear oil, the gear oil composition comprises a base oil and an additive, and the ratio of the base oil to the additive is 8:2, and the base oil is one of a mineral oil or a synthetic oil;

[0006] The additives specifically include Qidun RXF-24126 additive, T-304 dibutyl phosphite additive, T-115B alkyl phenol calcium sulfide, T-107 overbased synthetic magnesium sulfonate, T-701 synthetic barium sulfonate, T-501 di-tert-butyl-p-cresol, and T-203 dioctyl basic zinc salt of phosphorus sulfide;

[0007] The additive is made of the following raw materials in parts by weight:

[0008] Qidun RXF-24126 additive 3-8%, T-304 dibutyl phosphite additive 0.4-1.2%, T-115B sulfurized alkylphenol calcium 0.1-0.4%, T-107 overbased synthetic magnesium sulfonate 0.06-0.15%, T-701 synthetic barium sulfonate 0.07-0.12%, T-501 di-tert-butyl-p-cresol 0.08-0.14%, T-203 dioctyl basic zinc salt of phosphorus and sulfur 1-3.5%.

[0009] According to the above technical solution, the mineral oil is obtained by petroleum cracking, and the synthetic oil is specifically one of hydrocarbon synthetic oil and ester synthetic oil. When selecting mineral oil as the base oil of gear oil, the mineral oil needs to be refined.

[0010] According to the above technical solution, a method for preparing energy-saving repairable gear oil specifically includes the following preparation steps:

[0011] S1. Select gear oil base oil;

[0012] S2. Treat the base oil;

[0013] S3, mixing and preparing additives;

[0014] S4, filtering and cooling the obtained mixture;

[0015] S5. Take samples and test the packaging.

[0016] According to the above technical solution, in S1, selecting the gear oil base oil refers to selecting a suitable base oil according to the use environment and actual performance requirements of the gear, and the base oil includes mineral oil and synthetic oil.

[0017] According to the above technical solution, in S2, the base oil is processed according to the selected target base oil;

[0018] When selecting mineral oil as the base oil for gear oil, the selected mineral oil needs to be refined to remove impurities and impure substances;

[0019] During the refining process, mineral oil is treated by distillation and hydrofining to remove sulfur and nitrogen from the mineral oil.

[0020] When synthetic oil is selected as the base oil for gear oil, the selected synthetic oil needs to be subjected to a specific reaction treatment to synthesize a specific type of base oil so that the subsequently synthesized base oil has better stability and a low viscosity index.

[0021] According to the above technical solution, in S3, the additive mixing refers to adding the base oil selected in step S1 and processed in step S2 to the blending tank. Here, the cleanliness of the blending tank needs to be maintained to prevent impurities from being mixed into the oil product. The base oil is preliminarily heated by the blending tank to heat the base oil to 65-75°C. The base oil is heated in the blending tank by a bath heating method so that the base oil is evenly heated in the blending tank, and the base oil is gradually heated to a specified temperature by a gradient heating method.

[0022] Next, the additive to be added is added into a clean stirring tank, and the components of the additive are pre-mixed by the stirring tank to obtain a fully mixed additive raw material;

[0023] Then, the pre-mixed additive raw materials are added to the blending tank in the prescribed amount and order, and the addition ratio of the additive and the base oil is controlled. The additive and the base oil are fully stirred and mixed with the help of the mixing and stirring component in the blending tank to make the additive evenly dispersed in the oil base of the base oil. The stirring time is controlled to be 30-40 minutes and the stirring speed is 100-200r / min.

[0024] According to the above technical scheme, the additives are specifically: 5% of Qidun RXF-24126 additive, 0.8% of T-304 dibutyl phosphite additive, 0.2% of T-115B alkylphenol calcium sulfide, 0.1% of T-107 superbased synthetic magnesium sulfonate, 0.05% of T-701 synthetic barium sulfonate, 0.1% of T-501 di-tert-butyl-p-cresol, and 2% of T-203 dioctyl basic zinc salt of phosphorus and sulfur.

[0025] According to the above technical scheme, the Qidun RXF-24126 is an anti-wear agent and an extreme pressure additive, which improves the anti-wear and friction reduction properties of the gear oil, the T-304 dibutyl phosphite is an antioxidant, which prevents the gear oil from oxidizing and deteriorating, and prolongs the service life of the gear oil, and the T-115B sulfurized alkylphenol calcium is an antioxidant and a friction reducer, which improves the oil's antioxidant ability and wear resistance;

[0026] The T-107 overbased synthetic magnesium sulfonate and the T-701 synthetic barium sulfonate are both high base additives. The T-107 overbased synthetic magnesium sulfonate is used to improve the ability of lubricating oil to neutralize acidic substances and prevent corrosion inside the engine. The T-701 synthetic barium sulfonate is used to inhibit and reduce acidic substances generated during engine combustion.

[0027] The T-501 di-tert-butyl-p-cresol is a highly effective antioxidant and detergent, which can control the generation of solid particles in oil products. The T-203 dioctyl basic zinc salt of thiophosphorus is an anti-wear agent and a friction reducer.

[0028] According to the above technical solution, in S4, filtering and cooling the obtained mixture means filtering the mixture in the blending tank after the base oil and additives in the blending tank are fully stirred and mixed;

[0029] In the specific filtering process, the mixture is first cooled to room temperature in a natural state, and then filtered through a coarse filter and a fine filter in two steps with different filtering degrees to remove impurities in the mixture;

[0030] When filtering impurities in oil products, the oil products are divided into several groups for filtration, and the total amount of filtered material and the amount of oil remaining in the filtered material are recorded by group;

[0031] Impurities include: middle sediment particles, dust and top suspended matter;

[0032] After filtration, the filtration condition of each group of oil products is tested and the filtration effect S is calculated;

[0033] S=sγ×100%

[0034] s represents the filtration efficiency;

[0035] γ represents the exponential decay correction part of residual oil;

[0036] The specific calculation formula of s is as follows:

[0037]

[0038] Among them, e 沉 、e 灰 、e 悬 : They are the filtration efficiency coefficients of the middle sediment particles, dust and top suspended solids, respectively. They are the evaluation values ​​of impurity filtration by experts based on actual filtration experience. The value range is [0,1]. The higher the value, the higher the filtration efficiency.

[0039] M 原 Indicates the total amount of initial impurities in the oil;

[0040] The specific calculation formula of γ is as follows:

[0041]

[0042] Where r represents the residual oil content in the filtrate;

[0043] r 滤 Indicates the total amount of filtrate;

[0044] α represents the coefficient of residual oil influence, which is the influence value of residual oil on filtration efficiency evaluated by experts based on practical experience. The specific value range is [1,10]. The larger the value, the greater the influence of residual oil on filtration effect.

[0045] According to the above calculation, the filtering effect of each group of oil products is recorded as S1, S2, S3...S i ;

[0046] Continue to calculate the comprehensive filtering effect S 综合 :

[0047]

[0048] Among them, ω is the weight of each group of oil product filtering data, and M of each group of oil products is used. 原 To express.

[0049] According to the above technical solution, in S5, sampling, testing and packaging refers to performing quality testing on the oil product obtained in step S4, and packaging after the oil product is detected to meet the standard requirements;

[0050] During the testing process, the oil products are specifically tested for viscosity, viscosity-temperature, oxidation stability, wear, anti-corrosion and dust removal capabilities, antioxidant performance, and key indicators of mechanical impurities.

[0051] When it is detected that the performance indicators of the oil product do not meet the specified standards, it is necessary to improve the performance of the oil product by adjusting the proportion of additives and the ratio between additives and base oil. The performance adjustment is carried out until the performance of the oil product reaches the specified indicators after adjustment, and then it is packaged;

[0052] When the various performance indicators of the oil products are found to meet the prescribed standards, the qualified oil products are packaged;

[0053] When packaging the qualified products, the oil products are specifically filled, capped and labeled. The content of the label includes the oil product name, ingredients and applicable equipment.

[0054] Compared with the prior art, the present invention has the following beneficial effects: the present invention has a scientific and reasonable structure and is safe and convenient to use:

[0055] 1. By adding Qidun RXF-24126, T-304 dibutyl phosphite, T-115B alkyl phenol calcium sulfide and T-203 dioctyl thiophosphate basic zinc salt into the gear oil additive, Qidun RXF-24126 and T-203 dioctyl thiophosphate basic zinc salt can effectively improve the anti-wear and friction reduction properties of the prepared gear oil, and T-304 dibutyl phosphite can improve the antioxidant capacity of the gear oil, prevent the oil from oxidative deterioration, and extend the service life of the oil, while T-115B alkyl phenol calcium sulfide as an antioxidant and friction reducer can further enhance the antioxidant capacity and wear resistance of the oil;

[0056] By adding T-107 super-based synthetic magnesium sulfonate and T-701 synthetic barium sulfonate as high-base additives during the preparation of gear oil, the ability of the gear oil to neutralize acidic substances can be effectively improved, and the corrosion of the engine parts by the acidic substances generated during the engine combustion process can be inhibited and reduced, thereby achieving anti-corrosion protection of the interior of the engine;

[0057] In addition, by adding T-501 di-tert-butyl-p-cresol, it can be used as an oil detergent, which helps to control the formation of solid particles in the gear oil and keep the gear oil clean.

[0058] 2. By selecting the appropriate base oil according to the use environment and actual performance requirements, the subsequent base oil can be better applied in practice. At the same time, the base oil can be processed to meet the preparation requirements of the gear oil, avoiding the subsequent impact on the preparation quality of the gear oil. In the preparation process, the gear oil is subjected to uniform gradient heating treatment, and before the additives are added, the various components are pre-mixed to facilitate the preparation of the additives in a mixed state, so that the subsequent additives can be better dispersed in the base oil matrix to ensure the mixing and fusion effect.

[0059] 3. Through the means of filtering treatment, it is convenient to remove impurities in the mixture of base oil and additives to ensure the quality of the obtained oil. At the same time, after the gear oil is prepared, the gear oil is sampled and tested to facilitate a comprehensive test of the oil's viscosity, viscosity-temperature, oxidation stability, wear resistance, corrosion resistance, dust removal ability and oxidation resistance. By testing the key indicators of the oil, it is ensured that all performance of the oil meets the prescribed standards, so that the gear oil can be better used.

[0060] 4. By recording the filtration conditions of oil products and calculating the filtration effect of oil products based on the recorded data, we can control the filtration of impurities during the preparation process of oil products, so as to further control the quality of oil products until satisfactory oil quality is achieved. This can guarantee the quality of oil products to a certain extent, and calculate specific data to further ensure that the filtration of the oil products themselves meets the standards.
