Abstract

The invention provides a low-odor automobile switch lubricating grease composition. The low-odor automobile switch lubricating grease composition comprises the following components in parts by weight:62-93 parts of base oil, 5-20 parts of a thickening agent and 2-18 parts of a solid lubricant. The invention also discloses a preparation method of the low-odor automobile switch lubricating grease composition. The low-odor automobile switch lubricating grease composition prepared by adopting fumed silica to thicken poly-alpha olefin base oil and adding the solid lubricant has an extremely low odor grade. Through the test of VS-01.00-L-06005-A1-2018 Test Specification for Odor of Nonmetallic Materials in Vehicles, the odor grade is 1.0-1.5 grade, which is reduced by one grade or more than onegrade compared with the odor of the lubricating grease in the prior art. The automobile switch lubricating grease composition disclosed by the invention also has good colloid stability, wear resistance, friction reduction, shearing resistance and excellent high and low temperature performance, is suitable for lubricating and protecting various switches, and is also suitable for lubricating various parts of an automobile cockpit.

Description

technical field [0001] The invention relates to the technical field of low-odor lubricating grease, in particular to a low-odor automotive switch grease composition and a preparation method thereof. Background technique [0002] The car switch is a device used to control the power supply of electrical appliances, signal on and off, and adjust the size of the current signal. Vehicle switches are divided into four types of switches according to their positions and functional requirements on the vehicle, namely steering column switch assembly, door guard panel switch assembly, instrument panel switch assembly, and contact switch assembly. According to the purpose, there are more than ten sub-categories such as ignition switch, cruise switch, rearview mirror switch, glass lift switch, headlight switch, and air conditioner switch. [0003] The car switch is mainly composed of a cover plate, a slider, a spring point, a contact, a contact piece, a base, etc. Its working principle ...
