Abstract

The invention relates to the technical field of lubricating greases, and discloses a lubricating grease composition of an automobile steering combination switch. The lubricating grease composition comprises the following components in percent by mass: 85-90% of a base oil and 10-15% of a thickener, and comprises in percent by the total mass of the above two components: 2-4% of a tackifier, 0.5-1.5% of an extreme pressure anti-wear agent, 0.4-1.6% of an antioxidant, and 4.0-6.0% of a solid lubricant. According to the lubricating grease composition of the automobile steering combination switch and a preparation method, the overall formula is simple, the lubricating grease for the automobile steering combination switch has the characteristics of excellent adhesion, plastic compatibility, shear resistance, wear reduction, noise reduction, electrical conductivity and long life, the practical performance of the lubricating grease is improved, the lubricating grease is suitable for using in the contact friction between a metal and a plastic, a plastic and a plastic in the temperature range of 40 DEG C-130 DEG C, the service life of a combination switch for automobiles can be effectively improved, problems of abnormal noise, short circuit, jam and the like of the combination switch for automobiles can be effectively avoided, and the use is convenient.

Description

technical field [0001] The invention relates to the technical field of lubricating grease, in particular to a composition and a preparation method of lubricating grease for an automobile steering combination switch. Background technique [0002] The combination switch is a switch that is often introduced as a power source in the electrical control circuit. It can be used to directly start or stop the small power machine or make the small power machine carry out forward and reverse rotation. The car steering combination switch integrates various vehicle The function of the electrical switch, and adopts ergonomic design, replaces the switch with single function and separate installation, such as push-pull switch and panel button switch. The switch from separate switch to combined switch is a great progress in the automotive electrical system. [0003] Lubricating grease is often used in combination switches. At the same time, there are many places where lubricating grease is u...
