Abstract

The invention discloses a thixotropic lubricating agent. Based on the total weight of the lubricating agent, the lubricating agent comprises the following components: 10-25wt% of base oil, 10-25wt% of paraffin wax, 35-60wt% of oiliness solvent, 10-25wt% of extreme pressure antiwear agent and 0.3-1wt% of antirust agent. The invention also discloses a preparation method of the lubricating agent. The method comprises the following steps of: firstly heating the base oil, the oiliness solvent and the paraffin wax to 80-90 DEG C while stirring till the paraffin wax is completely molten, then adding the extreme pressure antiwear agent and the antirust agent, stirring for 30 minutes under the condition that temperature is maintained to be 80-85 DEG C, and then naturally cooling, thus obtaining the lubricating agent. The invention also discloses the application of the thixotropic lubricating agent in a metal tapping process.

Description

technical field [0001] The invention relates to the field of lubricants, in particular to a thixotropic lubricant used for metal tapping, and also provides a preparation method of the lubricant. Background technique [0002] Tapping is a basic operation skill of a fitter. Since the tapping cone needs to cut the internal thread in the working bottom hole during tapping, the cutting difficulty is more difficult than machining the external thread. The tapping head used in the tapping operation is in contact with the workpiece. It will produce a lot of friction and high temperature. In production practice, there are often thread rotten teeth, tapping head chipped teeth, and broken cones, which affect the quality of processed parts and even the entire product. Factors affecting the tapping effect include not only the material of the tapping cone, thermal effect, the diameter of the bottom hole of the thread, and the operating factors of the tapping cone, but also the geometry and...
