Description
Technical Field
The invention relates to lubricating oil, in particular to self-repairing lubricating oil for a cam mechanism and a preparation method thereof.
Background
The mechanical equipment transmission operation depends on a friction pair. According to the tribology survey report released by the Chinese institute of engineering, the economic loss caused by frictional wear in China accounts for 4.5% of GDP every year, and the consumed energy accounts for 1/3% of the annual exploitation amount.
Lubricating oil can reduce friction, but the existing lubricating oil has certain defects:
firstly, the repair layer is easy to fall off and deposit is formed at the bottom of the equipment, so that the performance of the equipment is damaged;
secondly, the formation of the friction layer needs to be started after the surfaces of the friction pair are greatly worn, and the unworn surfaces of the friction pair cannot form the layer;
thirdly, the friction pair generates huge noise due to overlarge friction force;
fourth, the composition of the lubricant is complex and difficult to prepare.
Therefore, the research and development of the anti-wear, anti-friction and self-repairing technology which can reduce the friction loss and has a certain self-repairing function are imperative.
Disclosure of Invention
The invention aims to provide self-repairing lubricating oil for a cam mechanism and a preparation method thereof, aiming at the defects in the prior art, a protective layer is formed by metal friction, so that the surface of a metal friction part is modified, and further the loss caused by friction is improved and reduced.
The technical solution of the invention is as follows: a self-repairing lubricating oil for a cam mechanism, comprising: the vermiculite powder, the silicon dioxide, the oiliness agent and the base oil comprise the following components:
vermiculite powder: 1-4 g;
silicon dioxide: 1-4 g;
an oiliness agent: 1-4 g;
base oil: 1000 ml;
the oiliness agent is oleic acid or linoleic acid.
A preparation method of self-repairing lubricating oil for a cam mechanism comprises the following steps:
step 1: cleaning vermiculite and silicon dioxide, and drying;
step 2: grinding vermiculite to 100 μm with a ball mill, and grinding silicon dioxide to 5 μm with a ball mill respectively;
and step 3: adding 1-4 g of the vermiculite powder obtained in the step 2 into 1-4 g of an oily agent, performing ultrasonic oscillation for 1-2 h at 20 ℃ to disperse the vermiculite powder in the oily agent, and grinding to 0.5-1 mu m to obtain modified vermiculite powder;
and 4, step 4: uniformly dispersing the modified vermiculite powder and 1-4 g of silicon dioxide powder into 1000ml of base oil, and performing ultrasonic oscillation for 1-2 hours at 20 ℃ to obtain the lubricating oil.
The specific method for cleaning and drying the vermiculite and the silicon dioxide in the step 1 is as follows: putting vermiculite powder or silicon dioxide powder into a high-temperature-resistant glass container, adding 80-100 ℃ hot water, soaking for 30-40 minutes, stirring by using a wood stick to enable impurities in the vermiculite powder to be layered with vermiculite or impurities in the silicon dioxide powder to be layered with silicon dioxide, soaking for 10 minutes, pouring out floating impurities and water, rinsing for a plurality of times, drying, naturally evaporating the moisture of the vermiculite powder or the silicon dioxide powder to 30-40% of water content, then putting into a drying device for further drying for 30-40 minutes, and drying the moisture content of the vermiculite powder or the silicon dioxide powder to be below 3%.
The oiliness agent is a compound containing a polar atom such as sulfur, oxygen, nitrogen, phosphorus, or the like, or a group such as a hydroxyl group, a carboxyl group, or the like.
In the step 4, at least 1g of modified vermiculite powder is contained in each 1000ml of base oil.
In the step 4, at least 1g of modified silicon dioxide powder is contained in every 1000ml of base oil.
The working principle of the self-repairing lubricating oil for the cam mechanism is as follows: the vermiculite mineral is hydrous magnesium silicate with a layered structure, has an extremely low friction coefficient, and can release silicon-oxygen bonds easy to combine with a metal surface after friction. Therefore, when the material is added into lubricating oil, a repairing film which can be continuously formed under the action of friction energy can replace metal abrasion on the surface of a friction pair, and the effect of friction self-repairing is achieved; and the repairing film is not easy to fall off, and is beneficial to improving the wear resistance and the antifriction performance of the friction pair.
The silicon dioxide ultrafine powder can enter, deposit and fill in a frictional furrow, and a repairing film which can be continuously formed under the action of frictional energy and superparamagnetism shown by the silicon dioxide ultrafine powder is utilized to replace the surface metal abrasion of a friction pair.
The beneficial technical effects of the invention are as follows: (1) the material has a high flash point and is suitable for friction surfaces of a large number of friction pairs; (2) the lubricating oil is not required to be added again when being replaced every time, and the service life is long; (3) can be added into various friction pairs with different new and old degrees, and forms a layer on the surface; (4) the noise generated by the cam friction pair can be effectively reduced.

the self-repairing lubricating oil for the cam mechanism can be directly added to a friction pair part of the cam as lubricating oil for use, and can also be used as a lubricating oil additive, diluted into other lubricating agents according to a certain proportion and added to the friction pair part for use.
The self-repairing lubricating oil for the cam mechanism can be added to the unworn friction pair part to play a pre-protection role on the friction pair, and can also be added to the abraded friction pair part to form a self-repairing layer on the surface of the friction pair.
Lubricating oil or lubricating grease added with the self-repairing lubricating oil for the cam mechanism enters gaps of the friction pair to play a role in reducing friction in a micro-bearing state, so that the surface of the friction pair is prevented from being further abraded.
Lubricating oil or lubricating grease added with the self-repairing lubricating oil for the cam mechanism enters gaps of the friction pairs, and the surfaces of the friction pairs are polished by solid particles.
The active atoms released by the self-repairing lubricating oil for the cam mechanism react with the polished surface of the friction pair under the action of load to generate a metal self-repairing layer to replace the surface of the friction pair to carry out mechanical transmission so as to be abraded.
Vermiculite contained in the self-repairing lubricating oil for the cam mechanism can effectively reduce noise generated by friction.

base oil: 1000 ml;
the oiliness agent is oleic acid or linoleic acid.
2. The method of preparing the lubricating oil of claim 1, comprising the steps of:
step 1: cleaning vermiculite and silicon dioxide, and drying;
step 2: grinding vermiculite to 100 μm with a ball mill, and grinding silicon dioxide to 5 μm with a ball mill respectively;
and step 3: adding 1-4 g of the vermiculite powder obtained in the step 2 into 1-4 g of an oily agent, performing ultrasonic oscillation for 1-2 h at 20 ℃ to disperse the vermiculite powder in the oily agent, and grinding to 0.5-1 mu m to obtain modified vermiculite powder;
and 4, step 4: uniformly dispersing the modified vermiculite powder and 1-4 g of silicon dioxide powder into 1000ml of base oil, and performing ultrasonic oscillation for 1-2 h at 20 ℃ to obtain the lubricating oil according to claim 1.
3. The method for preparing the vermiculite according to the claim 2, characterized in that the step 1 of washing the vermiculite and the silicon dioxide and drying the vermiculite is realized by the following specific method: putting vermiculite powder or silicon dioxide powder into a high-temperature-resistant glass container, adding 80-100 ℃ hot water, soaking for 30-40 minutes, stirring by using a wood stick to enable impurities in the vermiculite powder to be layered with vermiculite or impurities in the silicon dioxide powder to be layered with silicon dioxide, soaking for 10 minutes, pouring out floating impurities and water, rinsing for a plurality of times, drying, naturally evaporating the moisture of the vermiculite powder or the silicon dioxide powder to 30-40% of water content, then putting into a drying device for further drying for 30-40 minutes, and drying the moisture content of the vermiculite powder or the silicon dioxide powder to be below 3%.
