Problems solved by technology

[0002] Most of the cement mixer trucks in the prior art are lubricated with 00# lubricating grease. This kind of lubricating grease has two problems in actual use. It is too hard to reach the friction surface. Secondly, even if the existing lubricant is suitable for hardness and softness, its lubricity and wear resistance are not ideal.
However, the gear box currently uses 460# heavy-duty industrial gear oil, which is a general-purpose product in the industry, and its adhesion performance is not ideal for the working environment of the gear box.
Waste oil is a problem that people have paid more attention to in recent years. It is related to people's dietary health. If the outlet of waste oil is not solved, it is impossible to prevent waste oil from returning to the table with the existing detection methods and supervision system.

Abstract

The invention discloses a special industrial lubricant for a cement mixer and a reduction box, and a method for preparing the special industrial lubricant. The special industrial lubricant is prepared from raw materials according to weight by part as follows: 5-20 parts of drainage oil, 5-20 parts of dioctadecyl dimethyl ammonium modified bentonite, 60-90 parts of 100# machine oil and 0.5-2 partsof sodium hydroxide. The method provided by the invention comprises the following steps: removing solid impurities from the drainage oil at first; after removing moisture through heating, mixing the drainage oil with a base oil and organic modified bentonite; taking a small quantity of alkali as a catalyst, and forming excellent-performance special industrial lubricant at a certain temperature through a certain period of time. The special industrial lubricant provided by the invention is convenient for filling if being applied to the cement mixer, and capable of quickly reaching a frictional surface, and has excellent anti-rust and anti-friction properties. If the special industrial lubricant is applied to the reduction box, the toothed surface of the reduction box can have good adhesion force and excellent anti-friction and anti-extreme-pressure performances; and the special industrial lubricant is capable of well solving the usage problem of the drainage oil and provides a good way for solving the problem of reusing the drainage oil for meals.

Description

technical field [0001] The invention belongs to the technical field of special industrial lubricants, and in particular relates to a special industrial lubricant for cement mixer trucks and reduction boxes and a preparation method thereof. Background technique [0002] Most of the cement mixer trucks in the prior art are lubricated with 00# lubricating grease. This kind of lubricating grease has two problems in actual use. Hard, can not reach the friction surface, the second is that the existing lubricant even if the hardness is appropriate, its lubricity and wear resistance are not ideal. However, the gear box currently uses 460# heavy-duty industrial gear oil, which is an industrial general product, and its adhesion performance is not ideal for the working environment of the gear box. Waste oil is a problem that people have paid more attention to in recent years. It is related to people's dietary health. If the outlet of waste oil is not solved, it is impossible to preven...
