Example Embodiment

[0016] Example 1:

[0017] The preparation method of the ZIF-8 material filled with sulfur-containing thiophene: 100mg of activated ZIF-8 material (BanerjeeR, PhanA, WangB, KnoblerC, FurukawaH, O'KeeffeM, etal. High-throughput synthesis of zeoliticimidazolateframeworks and applicationtoCO 2 capture.Science[J].2008,319(5865):939-43.) soaked in 10mL thiophene (C 4 H 4 S. Place the solution of Sigma-Aldrich (Shanghai) Trading Co., Ltd. in a polytetrafluoroethylene reactor and place it in an oven at 100±20°C for 7 days. After the reaction is over, use a centrifuge to remove the obtained product. Water ethanol (CH 3 CH 2 OH, Aladdin Reagent (Shanghai) Co., Ltd.) was washed to neutrality and dried at room temperature to obtain thiophene ZIF-8 material.

[0018] Add the original sample ZIF-8 material directly to the base lubricant liquid paraffin as a lubricating additive. The addition amount is 0.25wt% of the total mass percentage. Place it in a KQ218 ultrasonic oscillator and shake for 6...

Example Embodiment

[0027] Example 2:

[0028] The preparation method of chlorobenzene ZIF-8 material is the same as that of Example 1, the difference is: the reagent containing chlorine element used in this example: 10 mL of chlorobenzene (C 6 H 5 Cl, Aladdin Reagent (Shanghai) Co., Ltd.).

[0029] The lubricating oil sample containing 1.0 wt% of ZIF-8 material is the same as that of Example 1, except that the base lubricating oil is poly-alpha olefin.

[0030] The prepared chlorobenzene ZIF-8 material was directly added to the base lubricating oil poly alpha olefin as a lubricating additive, the addition amount was 1.0wt% of the total, and placed in a KQ218 ultrasonic oscillator for 60 minutes to obtain a uniformly dispersed content Lubricant sample of 1.0 wt% chlorobenzene ZIF-8 material.

[0031] Use a four-ball friction and wear tester to evaluate the maximum seizure-free load ( P B ) And anti-friction and anti-wear performance. The measured data are shown in Table 2.

Example Embodiment

[0036] Example 3

[0037] The preparation method of dimethyl sulfoxide ZIF-8 material is the same as that of Example 1, the difference is: 10mL thiophene is replaced with 10mL dimethyl sulfoxide (C 2 H 6 OS, Aladdin Reagent (Shanghai) Co., Ltd.).

[0038] The lubricating oil sample containing 2.0 wt% of ZIF-8 material is the same as in Example 1, except that the base lubricating oil liquid paraffin is replaced with mineral oil 100SN.

[0039] The prepared dimethyl sulfoxide ZIF-8 material was directly added to the base lubricating oil poly alpha olefin as a lubricating additive, the addition amount was 2.0wt% of the total, and it was placed in a KQ218 ultrasonic oscillator for 60 minutes to shake to obtain dispersion Uniform lubricating oil sample containing 2.0wt% dimethyl sulfoxide ZIF-8 material.

[0040] Use a four-ball friction and wear tester to evaluate the maximum seizure-free load ( P B ) And anti-friction and anti-wear performance, the method is the same as in Example 1. T...

Abstract

The present invention discloses lubricating oil, a lubricating oil additive and a preparation method therefor, and belongs to the technical fields of functional materials and preparation thereof. The lubricating oil provided by the present invention consists of the following raw materials: with the total number of parts being 100, 98-99.75 parts of base lubricating oil and 0.25-2 parts of a lubricating oil additive. The lubricating oil additive is a sulfur- or chlorine-filled ZIF-8 material. The lubricating oil additive provided by the present invention is simple in preparation method, convenient and easy in application, and stable in performance. Application of the lubricating oil additive product provided by the present invention can effectively improve the bearing capability of the lubricating oil.

Description

technical field [0001] The invention relates to a lubricating oil, a lubricating oil additive and a preparation method thereof, and belongs to the technical field of functional materials and their preparation. Background technique [0002] For mechanical equipment operating in harsh environments such as low temperature, high speed, and heavy load, the lubrication often belongs to the boundary lubrication mode. In this case, reasonable lubricating oil additives, especially extreme pressure additives, are particularly important. As an additive to improve the lubricating performance of lubricating oil, materials containing sulfur and chlorine elements react chemically with the friction surface in the contact area of ​​the friction surface under high temperature conditions to ensure the bearing performance of the lubricating oil. The application of new lubricating materials and technologies can achieve the purpose of protecting friction pairs and saving energy. Therefore, more ...
