Problems solved by technology

[0002] Metal or alloy materials with high hardness, such as stainless steel, are one of the more difficult materials to process. They need to bear high loads during processing, which can easily lead to wear of workpieces and processing tools, especially when the equipment is under high load and high speed conditions. When running under high pressure, the metal surface is prone to scratches and sintering on the contact surface. The lubricating oil used in metal processing needs to have good lubricity, extreme pressure and anti-wear properties, but the effect of using lubricant alone is not ideal.

Embodiment 1-6

[0034] The friction modifier described in this embodiment includes the following components in parts by weight, as shown in Table 1:

[0035]

[0036] Table 1

[0037] The preparation method of embodiment 1-6 friction modifier specifically comprises the following steps:

[0038] (1) Add polyisobutylene succinic anhydride, hydrogenated coconut oleic acid, adipic acid, pentaerythritol and trimethylolpropane to the reactor, add 0.32 parts by weight of monobutyltin oxide, nitrogen, and heat up;

[0039] (2) When the temperature rises to 130°C, keep increasing the temperature by 10°C per hour;

[0040] (3) When the temperature rises to 200°C, keep the temperature for reaction for 3 hours;

[0041] (4) Vacuumize and react until the pH value of the product is less than 5 and the viscosity is greater than 5500mm 2 / s, the material can be cooled and discharged.

experiment example 1

[0047] In order to evaluate the lubricating effect of the friction modifier of the present invention applied in metalworking oil, this experimental example adopts four-ball test to measure the maximum non-seizing load (P B ), sintering load (P D ), long-term friction wear scar diameter (D). in:

[0048] Maximum non-jamming load (P B ): Measured according to the national standard GB / T 3142-82 lubricant bearing capacity test method; the conditions are as follows: time 10 seconds; speed 1450 rpm; temperature 27±8°C, lock 68±7N m;

[0049] Sintering load (P D ): Measured according to the national standard GB / T 3142-82 lubricant bearing capacity test method; the conditions are as follows: time 10 seconds; speed 1450 rpm; temperature 27±8°C, lock 68±7N m;

[0050] Long-term friction and wear scar diameter (D): measured according to the industry standard SH / T 0189-92 lubricating oil anti-wear performance test method; the conditions are as follows: time 60 minutes; speed 1200 rpm;...

Abstract

The invention relates to a friction modifier as well as a preparation method and application thereof. The friction modifier comprises the following components in percentage by weight: 20-40 percent of polyisobutylene succinic anhydride, 35-45 percent of hydrogenated coconut oleic acid, 3-20 percent of adipic acid, 5-15 percent of pentaerythritol and 2-10 percent of trimethylolpropane. The friction modifier can be applied to the preparation of metal processing oil, and the lubricating bearing capacity, the wear resistance and the lubricating property of the metal processing oil prepared by the friction modifier are effectively improved.

Description

technical field [0001] The invention relates to the field of lubricants, in particular to a friction modifier and its preparation method and application. Background technique [0002] Metal or alloy materials with high hardness, such as stainless steel, are one of the more difficult materials to process. They need to bear high loads during processing, which can easily lead to wear of workpieces and processing tools, especially when the equipment is under high load and high speed conditions. When running under high pressure, the metal surface is prone to scratches and sintering on the contact surface. The lubricating oil used in metal processing needs to have good lubricity, extreme pressure and anti-wear properties, but the effect of using lubricant alone is not ideal. . Therefore, it is necessary to provide a friction modifier that can improve the bearing capacity, anti-wear performance and lubricating performance of the lubricant, so as to reduce or avoid the direct conta...
