preparation example Construction

[0036] The invention provides a method for preparing a high-temperature anti-corrosion lubricating oil composition, comprising the following steps:

[0037] 50-80 parts by weight of PAO40 polyalphaolefin, 15-30 parts by weight of PAO20 polyalphaolefin, 5-20 parts by weight of decyl ester and 0.5-5 parts by weight of antioxidant are mixed to obtain a high-temperature anti-corrosion lubricating oil combination;

[0038] Described antioxidant is the steam turbine oil compound agent that BASF company provides, and the trade mark is IR2030D.

[0039]In the preparation method provided by the present invention, the high-temperature anti-corrosion lubricating oil provided by the present invention can be obtained by directly mixing the polyalphaolefin with the grade of PAO40, the polyalphaolefin with the grade of PAO20, decyl ester and antioxidant in proportion combination. Wherein, the raw materials for preparing the composition preferably further include one or more of antirust age...

Abstract

The invention belongs to the technical field of the petrochemical engineering, and particularly relates to a high-temperature anticorrosion lubricating oil composition and a preparation method thereof. The provided composition comprises the following components by weight: 50-80 parts of poly a-alkene with a shop sign PAO40, 15-30 parts of poly a-alkene with a shop sign PAO20, 5-20 parts of caprate, and 0.5-5 parts of an antioxidant. The antioxidant is a steam turbine oil complexing agent provided by the BASF Aktiengesellschaft, and the shop sign is IR 2030D. The poly a-alkene with the specific viscosity is used as base oil, the suitable amount of the specific ester oil and the antioxidant is added to obtain the high-temperature anticorrosion lubricating oil composition with the excellent performance. The experimental result shows that the provided composition has the good high-temperature resistance, good low-temperature performance and viscosity-temperature property and low volatilization loss, and is capable of satisfying the use of hot roller motor bearings under the working conditions of high speed, high temperature and large load.

Description

technical field [0001] The invention belongs to the field of petrochemical industry, and in particular relates to a high-temperature anti-corrosion lubricating oil composition and a preparation method thereof. Background technique [0002] The hot roller motor is used in the high-speed spinning production line and is the key component of the FDY chemical fiber filament spinning machine with high technical content. Due to the poor production environment of chemical fiber spinning, in addition to noise, fiber dust and oily smoke, the ambient temperature is also relatively high. Under normal circumstances, the heat roller motor works under the condition of continuous high-speed operation. In addition to the heat generated by the motor itself, the hot drafting rollers are also transferring heat through the motor shaft. However, the motor bearings are extremely susceptible to wear in this situation. The high-speed spinning production line has extremely high requirements on the...
