[0019] The specific production and preparation methods of the biodegradable low-smoke metal extrusion tapping oil include:

[0020] 1) Mixing and stirring: Take 2-5 parts of active sulfurized fatty acid ester extreme pressure agent, 2-5 parts of inactive sulfurized fatty acid ester / hydrocarbon extreme pressure agent, 1-5 parts of phosphate ester anti-wear lubricant, low viscosity synthetic Pour the remaining amount of ester base oil into the container in sequence, and stir continuously for 20-30 minutes until it is completely mixed;

[0021] 2) Heating and stirring: the mixture is continuously heated by a heating device, and when the temperature of the mixture is heated to 40-50 degrees Celsius, it is continuously stirred again until the mixture is clear and transparent;

[0022] 3) cooling and standing: put the mixture obtained in step 2 aside to cool and let stand for 20-30min to obtain the product.

[0023] The base oil is a low-viscosity synthetic ester base oil.

Abstract

The invention belongs to the technical field of chemical products, and particularly discloses biodegradable low-smoke metal extrusion tapping oil. The biodegradable low-smoke type metal extrusion tapping oil is prepared from the following specific raw materials in percentage by weight: 2-5% of an active sulfurized fatty acid ester extreme pressure agent, 2-5% of an inactive sulfurized fatty acid ester / hydrocarbon extreme pressure agent, 1-5% of a phosphate anti-wear lubricant and the balance of low-viscosity synthetic ester type base oil. Therefore, during work, the obtained extrusion tapping oil can be timely brought into a deformation area so as to provide the instantaneous lubricating effect, the continuous lubricating effect can be provided between a formed thread and a screw tap, the overall smoke generation amount during a tapping process is significantly lower than traditional tapping oil, and the biodegradation rate of the raw material components is 90% or more.

Description

technical field [0001] The invention relates to the technical field of chemical products, in particular to a biodegradable low-smoke metal extrusion tapping oil. Background technique [0002] Metal extrusion tapping is to use a specific tap to press into the inner wall of the metal casing to form a thread to make a fixed connection for the pipeline. It is characterized by cold extrusion deformation processing, and the pressure and friction are very large. It is required that the lubricant can still form a solid oil film in the deformation zone to lubricate and make the tapping go smoothly. Therefore, the lubricant is required to have a strong Extreme pressure and anti-wear properties. [0003] Extrusion tapping belongs to metal forming processing. Compared with cutting processing, metal forming processing does not cut off processing materials, so that the total amount of processing materials remains unchanged, so raw materials can be saved. Extrusion tapping is used to pro...
