Problems solved by technology

Under some extreme conditions such as high temperature and high pressure, because the oil in the frame escapes too quickly, causing dryness, the lubrication effect cannot be maintained for a long time, and frequent replacement of grease is required, resulting in equipment shutdown and manpower waste

Embodiment 1

[0030] Step 1: Weigh 100g of dimer acid, 10g of lanthanum oxide, 8g of boric acid, and 5g of phosphoric acid and add them into a stirrer, stir and heat to 120°C, and fully react for 2 hours.

[0031] Step 2: When the temperature is lowered to below 45°C, add 8g of diethylaminoethanol and stir for reaction for 2 hours. After being homogenized by homogenizing equipment, a translucent substance is obtained, which is a grease composition.

[0032] The above-mentioned grease composition can be used as a grease as it is.

[0033] The above grease composition was applied to the TIMKEN experimental machine for repair experiments:

[0034] Add 32# mechanical oil to the oil tank of the TIMKEN experimental machine, install new rollers, turn on the motor switch, add weights continuously, and when the weights are added to 50 pounds, the motor makes a sharp noise. The post has worn about 6.5mm in diameter (longitudinal), and the worn surface is relatively rough. Replace the mechanical oil...

Embodiment 2

[0036] Step 1: Weigh 100g of dimer acid, 8g of cerium oxide, 5g of boric acid, and 3g of phosphoric acid and put them into a stirrer, stir and heat to 100°C, and fully react for 3 hours.

[0037] Step 2: When the temperature is lowered to below 45° C., add 5 g of diethylaminoethanol and stir to react for 1 hour. After being homogenized by homogenizing equipment, a translucent substance is obtained, which is a grease composition.

[0038] Weigh 50g of the above lubricating grease composition, 30g of carnauba wax, 10g of sodium stearyl glutamate, and 10g of jojoba oil, heat it to about 100°C, place it in a homogenization device for homogenization for 1 hour, and it is a kind of Repair grease.

Embodiment 3

[0040] Step 1: Weigh 1000g of dimer acid, 90g of lanthanum oxide, 70g of boric acid, and 40g of phosphoric acid and put them into a stirrer, stir and heat to 110°C, and fully react for 2.5 hours.

[0041] Step 2: When the temperature is lowered to below 45° C., add 60 g of diethylaminoethanol and stir for 1.5 hours. After homogenization treatment by a homogenizer, a translucent substance is obtained, which is a grease composition.

[0042] Weigh 400g of the above lubricating grease composition, 400g of carnauba wax, 100g of sodium stearyl glutamate, 100g of jojoba oil, 5g of antioxidant (Irganox L57) and heat it to about 100°C, place it in a homogenization equipment Treated for 1.5 hours, it is a repairable grease.

[0043] Carry out the roller stability test of the high temperature resistant grease prepared above according to SH / T0122:

[0044] project Before rolling 2 hours after rolling experimental method Dropping point ℃ 202 202 GB / T4929 Pre...

Abstract

The invention provides a lubricating grease composition, which is characterized in that it is prepared from dimer acid, rare earth oxide, boric acid, phosphoric acid, and diethylaminoethanol, and the weight-number ratio of the components is: dimer acid 100; rare earth oxide 8‑10; boric acid 5‑8; phosphoric acid 3‑5; diethylaminoethanol 5‑8. The present invention also provides a repairable lubricating grease, which is manufactured by the following components by weight percentage: 40-50% of lubricating grease composition; 30-40% of carnauba wax; 10-20% of sodium stearyl glutamate %; jojoba oil 5‑10%. The lubricating grease composition prepared by the present invention is a boron-phosphorus-rare earth friction modifier, which has the effect of repairing the wear of the metal surface, and has good lubricity, rust resistance and biodegradability; carnauba wax has a higher Melting point, good lubricity and good degradability; sodium stearyl glutamate is a good organic thickener and surfactant, which can promote the biodegradation of other components; jojoba oil is a good biodegradable lubricant .

Description

technical field [0001] The invention belongs to the technical field of lubricating grease, and in particular relates to a repairable lubricating grease and a preparation method thereof. Background technique [0002] The traditional grease processing technology is: add animal and vegetable oil or fatty acid to inorganic base (such as sodium hydroxide, calcium hydroxide, lithium hydroxide, aluminum hydroxide, barium hydroxide, etc.) to prepare metal soap as thickener or use organic or Inorganic thickener, which is thickened by adding mineral oil or synthetic oil, is mainly to store mineral oil or synthetic oil in the framework of thickener, and store it in the thickener under the action of motion pressure and temperature. The oil in the chemical agent escapes to act as a lubricant, and exhibits paste-like physical properties under normal temperature and pressure. Under some extreme conditions such as high temperature and high pressure, because the oil in the frame escapes too...
