Problems solved by technology

[0005] At present, there is no lubricating grease specially used for car seat slide rails in the world. The lubricating greases in use mainly include lithium-based grease and lithium-complex grease. Because lithium-based ester and lithium-complex grease contain a large amount of lithium compounds , its fluidity is poor at a low temperature below -20°C, its lubricating performance is reduced, and the friction between the seat, the upper and lower rails and the sliding core increases, and it will cause poor sliding and noise when adjusting the seat position , it is difficult to meet the requirements of the seat slide rail,

Embodiment 1

[0032] Select 10 parts of dipolyurea thickener and 90 parts of HV1150 base oil according to the weight ratio and stir evenly. The 100°C kinematic viscosity of the HV1150 base oil is 5.5mm 2 / s,; stir and heat up to 130°C, keep for 30 minutes; mix 1 part of 2,6-di-tert-butyl-p-cresol; cool to room temperature, add 1 part of sodium petroleum sulfonate, stir well, and finally use three-wheel mill Grind 3 times to obtain a grease composition. The physical and chemical properties of the resulting grease are shown in Example 1 in Table 1.

Embodiment 2

[0034] Select 30 parts of dipolyurea thickener and 70 parts of PAO2 base oil by weight and stir evenly, the 100 ℃ kinematic viscosity of described PAO2 base oil is 2mm 2 / s,; stir and heat up to 130°C, keep for 30 minutes; mix 1 part of 2,6-di-tert-butyl-p-cresol; cool to room temperature, add 1 part of sodium petroleum sulfonate, stir well, and finally use three-wheel mill Grind 3 times to obtain a grease composition. The physical and chemical properties of the resulting grease are shown in Example 2 in Table 1.

Embodiment 3

[0036] Select 20 parts of dipolyurea thickener and 90 parts of HV1150 base oil and 90 parts of PAO10 base oil by weight and stir evenly, and the kinematic viscosity of the HV1150 base oil is 5.5mm2 / s, the kinematic viscosity of PAO10 base oil at 100°C is 10mm 2 / s; stir and heat up to 140°C, keep for 30 minutes; mix 1 part of 2,6-di-tert-butyl-p-cresol evenly; cool to room temperature, add 1 part of sodium petroleum sulfonate, stir evenly, and finally grind with a three-wheel mill 3 times to obtain a grease composition. The physical and chemical properties of the resulting grease are shown in Example 3 in Table 1.

Abstract

The invention provides a lubricating grease composition for seat slide rails of an automobile. The composition comprises 10 to 180 parts of base oil and 10 to 30 parts of a thickening agent, wherein, the thickening agent is dipolyurea or tetra-polyurea, and the base oil is mineral oil and / or synthetic oil. The lubricating grease composition provided in the invention has good heat resistance, can maintain good lubricating performance at a temperature in a range of -50 to 140 DEG C, produces no noise and has excellent wear resistance, anti-corrosion performance and anti-aging performance.

Description

technical field [0001] The invention relates to the field of lubricating grease and its preparation, in particular to an automobile seat lubricating grease. Background technique [0002] The key core components of passenger car seats include seat motors, slide rails, recliners, memory devices, etc. In addition to satisfying the function of riding, the seat can play the role of protecting passengers to the greatest extent when a traffic accident occurs. Therefore, OEMs have a very strict process for the design and testing of passenger car seats. The structure of the seat seems simple, but it requires a high technical content to meet the requirements of the complete vehicle. [0003] The seat slide rail is the most important component in the seat assembly and has a very high technical content. It is not only an important functional part, but also one of the automotive safety parts. The seat slide rail can be combined with the manual lock device to realize the manual adjustme...
