Lubricating grease for automobile safety belt system

Abstract

The invention relates to lubricating grease for an automobile safety belt system. The lubricating grease comprises the following components in parts by weight: 72-90 parts of base oil; 0.5 to 3 partsof lithium hydroxide; 5 to 12 parts of 12-hydroxystearic acid; 1.7 to 3.5 parts of a binary acid; 1.2 to 3 parts of boric acid; 0.6 to 7 parts of nano silicon dioxide; 0.4 to 2 parts of a friction reducing agent; wherein the base oil comprises at least one of mineral base oil, synthetic base oil or naphthenic base mineral oil. The lubricating grease provided by the invention is composite lithium-based lubricating grease, and as an innovation point of the invention, the lubricating grease is composite with a nano silicon dioxide material, especially a modified nano silicon dioxide material, andis a novel lubricating grease prepared by adding an antifriction agent. A safety belt in an automobile safety belt system is frequently and repeatedly stretched, the lubricating grease added with thefriction reducing agent is small in friction coefficient and good in stability, the overall wear resistance, heat resistance and other properties of the lubricating grease are improved through the modified nano silicon dioxide, and the use effect is good when the lubricating grease is applied to the automobile safety belt system.

Description

technical field [0001] The invention relates to the technical field of lubricating grease, in particular to an automotive safety belt system lubricating grease. Background technique [0002] The car seat belt is a safety device for restraining the occupant during a collision and avoiding a secondary collision between the occupant and the steering wheel and instrument panel during a collision or avoiding rushing out of the vehicle during a collision and causing death or injury. Because of the long-term frequent use of the car seat belt system, in order to facilitate retraction and expansion, it is necessary to add lubricating grease to improve the lubricating degree. After adding lubricating grease, it is generally not replenished or replaced. Therefore, the lubricating grease is required to have an extremely long service life, that is, a better Stability, wear resistance and low coefficient of friction. [0003] If the lubricating grease has problems such as poor wear resis...

AI Technical Summary

Problems solved by technology

[0003] If the lubricating grease has problems such as poor wear resistance and insufficient lubrication life in actual use, it may hinder the normal use of the car seat belt system. At the same time, replacing and replenishing the lubricating grease will also cause environmental pollution and waste of resources.
