Embodiment 1

[0017] Preparation method of ZIF-8 material filled with sulfur-containing thiophene: 100 mg of activated ZIF-8 material (BanerjeeR, PhanA, WangB, KnoblerC, FurukawaH, O'KeeffeM, et al. High-throughput synthesis of zeoliticimidazolateframeworksandapplicationtoCO 2 capture.Science[J].2008,319(5865):939-43.) soaked in 10mL thiophene (C 4 h 4 S, Sigma-Aldrich (Shanghai) Trading Co., Ltd.) solution, placed in a polytetrafluoroethylene reactor, placed in an oven at 100±20°C for 7 days, after the reaction was completed, the obtained product was used in a centrifuge Hydroethanol (CH 3 CH 2 OH, Aladdin Reagent (Shanghai) Co., Ltd.) to neutrality, and after drying at room temperature, the thiophene ZIF-8 material was obtained.

[0018] The original sample ZIF-8 material is directly added to the base lubricating oil liquid paraffin as a lubricating additive. Lubricating oil samples with wt% ZIF-8 material.

[0019] The prepared thiophene ZIF-8 material is directly added to the base ...

Embodiment 2

[0028] The preparation method of chlorobenzene ZIF-8 material is the same as embodiment 1, difference is: the reagent containing chlorine element that present embodiment adopts: 10mL chlorobenzene (C 6 h 5 Cl, Aladdin Reagent (Shanghai) Co., Ltd.).

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

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

[0031] Using the four-ball friction and wear testing machine to evaluate the maximum non-jamming load ( P B ) and anti-friction and anti-wear properties, the method is the same as in Example 1. The measured data are shown in Table 2. ...

Embodiment 3

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

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

[0039] Add the prepared dimethyl sulfoxide ZIF-8 material directly into the base lubricating oil polyalphaolefin as a lubricating additive, the addition amount is 2.0wt% of the total amount, and place it in a KQ218 ultrasonic oscillator for 60 minutes to obtain a dispersed Homogeneous lubricant oil sample containing 2.0 wt% DMSO ZIF-8 material.

[0040] Using the four-ball friction and wear testing machine to evaluate the maximum non-jamming load (P B ) and anti-friction and anti-wear properties, the method is the same as in Example 1. The measured data are shown in Table ...

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 ...
