preparation example Construction

[0055] The invention provides a kind of preparation method of tapping oil, comprising:

[0056] A) mixing paraffinic base oil, refined lard, chlorinated paraffin, rapeseed oil, sulfurized olefin, sulfurized fatty acid ester and calcium sulfonate to obtain a mixture;

[0057] B) The mixture is heated and stirred to obtain tapping oil.

[0058] The preparation method of the tapping oil provided by the invention firstly mixes paraffin base oil, refined lard, chlorinated paraffin, rapeseed oil, sulfurized olefin, sulfurized fatty acid ester and calcium sulfonate to obtain a mixture.

[0059] The above-mentioned reaction of the present invention is preferably carried out in a reactor, and the present invention does not limit the reactor, as long as those skilled in the art are familiar with it.

[0060] Wherein, the weight ratio of the paraffin-based base oil, refined lard, chlorinated paraffin, rapeseed oil, sulfurized olefin, sulfurized fatty acid ester and calcium sulfonate is ...

Embodiment 1

[0067]

Abstract

The invention provides a tapping oil. The tapping oil is prepared from, by weight, 50-80 parts of paraffin base oil, 2-10 parts of refined lard, 3-10 parts of chlorinated paraffin, 10-20 parts of rapeseed oil, 2-10 parts of sulfurized olefins, 3-10 parts of sulfurized fatty acid ester and 0.2-1 part of calcium sulfonate. According to the tapping oil, the paraffin base oil, the refined lard, the chlorinated paraffin, the rapeseed oil, the sulfurized olefins, the sulfurized fatty acid ester and the calcium sulfonate have a extreme pressure synergistic effect; particularly, the combination of thesulfurized olefins, the sulfurized fatty acid ester and the calcium sulfonate has an extreme pressure synergistic effect; the combination of the sulfurized olefins, the chlorinated paraffin synergistically increases the oil film strength. And the synergistic effect of the refined lard and the rapeseed oil can improve the boundary lubrication performance of the tapping oil.

Description

technical field [0001] The invention relates to the technical field of tapping oil, in particular to a tapping oil and a preparation method thereof. Background technique [0002] Tapping oil is blended with high-performance vulcanized lard and sulfurized fatty acid ester as the main agent. It is dedicated to tapping and thread rolling of carbon steel, stainless steel and other non-ferrous metals. It has excellent wear resistance and extreme pressure performance. , can effectively improve the finish of the workpiece, effectively prolong the life of the mold, no odor, and does not irritate the skin. [0003] Tapping oil contains a large amount of chloride additives, active vulcanized fatty oil and special lubricating additives. Due to its high lubricity, it can effectively reduce the cutting temperature, thereby obtaining the maximum cutting accuracy. It has been successfully applied to the high Difficult cutting, such as high-speed turning, drilling, tapping, broaching, hobb...
