Technical Field
The invention relates to the technical field of automobile engine lubricating oil, in particular to durable high-wear-resistance automobile diesel engine lubricating oil.
Background
At present, the lubricating oil for the diesel engine on the market cannot be used for a long time due to insufficient wear resistance, and needs to be replaced regularly, so that the cost is increased, and the environment protection is not facilitated, so that the research on the durable high-wear-resistance lubricating oil for the diesel engine of the automobile is necessary.

In order to overcome the defects of the prior art, the invention aims to provide a durable high-wear-resistance automobile diesel engine lubricating oil,
in order to achieve the purpose, the invention adopts the technical scheme that:

The alkali value of the calcium lignosulfonate detergent is 350-400 mgKOH/g.
The base oil is diester or triester synthesized by esterification of binary or ternary carboxylic acid with carbon number less than ten and glycol ether; the molecular weight is 8000-.
The modified ultrathin titanium sheet has the thickness of 0.015-0.025mm, the diameter of 0.05-0.1mm and the shape of a circle.
The preparation method of the modified ultrathin titanium sheet comprises the following steps: at room temperature, taking a clean ultrathin titanium sheet as an anode and metal platinum as a cathode, adding 0.2-0.3 mass percent of ammonium fluoride and ethylene glycol into water by using an external addition method to form a mixed solution in an electrolyte, oxidizing the ultrathin titanium sheet at an oxidation voltage of 60-80V for 25-40min, and forming a titanium dioxide nanotube array on the surface of the titanium sheet; through experimental study, the ultrasonic oscillation can prevent the carbon nano tubes from agglomerating and promote the carbon nano tubes to disperse, but the concentration of the dispersing agent has great influence on the dispersion of the carbon nano tubes, the dispersing effect of the carbon nano tubes is increased along with the increase of the concentration of the dispersing agent, but when the concentration of the dispersing agent exceeds 0.4g/L, the dispersing effect of the carbon nano tubes is reduced, the titanium sheet is taken out and placed in deionized water, the solute of the deionized water is sodium dodecyl sulfate, the concentration of the deionized water is controlled to be 0.35-0.4g/L, and under the condition, the titanium dioxide nano tube array on the surface of the ultrathin titanium sheet is removed through the ultrasonic oscillation and dried.
The invention has the beneficial effects that:
the modified ultrathin titanium sheet is added into the formula of the traditional automobile diesel engine lubricating oil to be used as a lubricating oil modifier, and is mainly used for improving the wear resistance and friction reduction performance of the lubricating agent;
because the surface of the conventional ultrathin titanium sheet is too smooth, the mechanical strength and the elastic modulus of the conventional ultrathin titanium sheet are still to be improved, and a large number of nano lattices which are uniformly arranged are formed on the surface of the titanium sheet in a modification mode, so that the friction coefficient of the lubricating oil can be effectively reduced.
