Problems solved by technology

[0004] The above-mentioned patents have done a lot of work to solve the thermal oxidation stability of high-temperature chain oil (such as evaporation loss, coking and carbon deposition performance). The research on the anti-wear performance of high-temperature chain oil is mainly concentrated There is less attention paid to wear performance. Under the situation of increasingly harsh actual working conditions, it is necessary to develop a high-temperature chain oil with excellent high-temperature anti-wear performance, which can effectively protect the smooth transmission of the chain, prolong the service life, and provide guarantee for safe production.

Embodiment 1

[0019] Add 0.36mol (49g) of pentaerythritol, 0.1075mol (15.7g) of adipic acid, 0.67mol (96.7g) of n-octanoic acid and 0.54mol (85.4g) of isononanoic acid into a 500ml three-neck flask equipped with a condenser tube and a water separator , solid superacid SO 4 2- / ZrO 2 0.196g, petroleum ether (90~120) 20ml, start stirring, raise the temperature to 160°C for reflux reaction for 4h, then raise the temperature to 200°C at a rate of 10°C / h, continue to keep warm for 4h, and the reaction ends. Distill the solvent and excess acid under reduced pressure at 0.95MPa and 200°C to remove the solvent and excess acid, then add 5% activated clay and stir at 100°C for 2h and filter to obtain the final product pentaerythritol complex ester 1.

Embodiment 2

[0021] Add 0.36mol (49g) of pentaerythritol, 0.164mol (24g) of adipic acid, 0.397mol (57.3g) of n-octanoic acid, 0.699mol (110.6g) of isononanoic acid, Solid Superacid SO 4 2- / ZrO 2 0.196g, petroleum ether (90~120) 20ml, start stirring, raise the temperature to 160°C for reflux reaction for 4h, then raise the temperature to 200°C at a rate of 10°C / h, keep it warm for 8h, and the reaction ends. Distill the solvent and excess acid under reduced pressure at 0.95MPa and 200°C to remove the solvent and excess acid, then add 5% activated clay and stir at 100°C for 2h and filter to obtain the final product pentaerythritol complex ester 2.

Embodiment 3

[0023] Take 92g of pentaerythritol complex ester 1 and add it to a 250ml beaker, then add 1.5g of butyl / octyl diphenylamine, 1g of nitrogen phenyl-α-naphthylamine, 0.5g of V9317, 1.5g of trioctyl phosphite, 1g of tricresyl phosphate, 1.5 gN,N-molybdenum di(dodecyl)dithiocarbamate, 0.8g benzotriazole, 0.2g T746, heated to 80°C and stirred for 1h to obtain the final product, which is designated as composition 1.

Abstract

The invention discloses a chain oil composition with excellent high temperature abrasion resistance. The composition is prepared from, by mass, 92%-96% of dipentaerythritol ester, 1%-3% of antioxygen composition, 2%-4% of abrasion resisting agent composition, 0.2%-0.8% of corrosion inhibitor and 0.2%-0.6% of antirust agent. Dipentaerythritol ester is prepared through the steps that pentaerythritol, binary acid and unitary saturated fatty acid react for 12-16 h at the temperature of 160 DEG C to 200 DEG C at the presence of a catalyst, and then reduced pressure distillation, hargil adsorption and filtering are carried out. The antioxygen composition is a composition of diphenylamine antioxygen, naphthylamine antioxygen and an amine antioxygen oligomer. The abrasion resisting agent composition is a composition of phosphite ester, phosphate and dialkyl dithiocarbamic acid molybdenum. Dipentaerythritol ester is adopted as base oil of chain oil, and the advantages of being high in flash point, low in frequency point, high in viscosity index, low in evaporation loss, not likely to coke and the like are achieved. Dipentaerythritol ester is reasonably compounded with an additive, and the high-temperature chain oil composition with the excellent high temperature abrasion resistance is obtained.

Description

technical field [0001] The invention relates to a chain oil composition with excellent high-temperature anti-wear performance, which belongs to the field of lubricating oil. Background technique [0002] Chain oil is a kind of industrial lubricating oil, which is used to lubricate various chains, prevent rust, reduce friction and wear, improve transmission efficiency and extend chain life. With the development of modern industry, the operating conditions of the chain are becoming more and more severe, the operating temperature is getting higher and higher, and the transmission speed is getting faster and faster. Therefore, the corresponding high temperature chain oil is required to have excellent high temperature stability and high temperature wear resistance. [0003] The base oil of high temperature chain oil can be divided into mineral oil type, polyether type and synthetic ester type. The operating temperature of ordinary mineral oil generally does not exceed 150°C, a...
