Embodiment 1

[0015] In terms of mass percentage, weigh 55% of liquid paraffin (boiling range 350-500°C), 20% of tricaprylic acid glyceride, 17.5% of ethylene glycol monoethyl ether, 2% of ethyl chloride, and 5% of Basic calcium sulfonate, 0.5% benzotriazole.

[0016] Add liquid paraffin, glyceryl tricaprylate, ethylene glycol monoethyl ether, ethyl chloride, calcium sulfonate and benzotriazole into the container in sequence at 60°C, stir until uniform and transparent, and cool to room temperature , and then filter the obtained filtrate to be cutting oil.

Embodiment 2

[0018] In terms of mass percentage, weigh 60% of liquid paraffin (boiling range 350-500°C), 16% of tricaprylic acid glyceride, 16.7% of ethylene glycol monoethyl ether, 1% of ethyl chloride, and 6% of sulfonic acid sodium nitrate, 0.3% benzotriazole.

[0019] Add liquid paraffin, glyceryl tricaprylate, ethylene glycol monoethyl ether, ethyl chloride, calcium sulfonate and benzotriazole into the container in sequence at 60°C, stir until uniform and transparent, and cool to room temperature , and then filter the obtained filtrate to be cutting oil.

Embodiment 3

[0021] In terms of mass percentage, 40% of liquid paraffin (boiling range 350-500°C), 45.9% of oiliness agent, 14% of extreme pressure agent and 0.1% of benzotriazole were weighed respectively. Among them, the oily agent is formed by mixing 30% tricaprylic acid glyceride and 70% ethylene glycol monoethyl ether, and the extreme pressure agent is formed by mixing 70% overbased sodium sulfonate and 30% ethyl chloride.

[0022] Add the above-weighed liquid paraffin, oily agent, extreme pressure agent and benzotriazole into the container in sequence at 60°C, stir until uniform and transparent, cool to room temperature, and then filter the resulting filtrate to become cutting oil.

Abstract

The invention discloses cutting oil, which comprises the following components in percentage by mass: 40 to 60 percent of liquid paraffin, 20 to 50 percent of oiliness improver, 4 to 18 percent of extreme-pressure additive and 0.1 to 2 percent of benzotriazole, wherein the oiliness improver is a mixture of 30 to 90 percent of tricaprylin and 10 to 70 percent of glycol ethyl ether. The invention provides the cutting oil which has good effects of lubricating, cooling, rust protection and cleaning and has good environment-friendly performance.

Description

technical field [0001] The invention belongs to the field of metal processing, in particular to a cutting oil used in the metal processing process. Background technique [0002] Cutting oil is an indispensable process material in metal processing. The reasonable use of cutting oil in the cutting process can effectively reduce the friction between the tool and the workpiece during the cutting process, improve the heat dissipation conditions, thereby reducing the cutting force, power consumption, cutting temperature and tool wear, and prolong the service life of the tool. With the continuous development of modern metal cutting technology, processing equipment is developing in the direction of high speed, high function and automation, and the workpiece material has become superhard and diversified, which increases the difficulty of processing, and the requirements for cutting oil performance are increasing. In addition, due to the improvement of people's awareness of environme...
