Problems solved by technology

[0004] The existing disclosed inventions have the defects of complex components and unstable performance; the impact on the performance of lubricating oil is not considered; only the effect of friction reduction and anti-wear is involved, and no clear dynamic wear self-repair effect is given.
Such as Chinese patent CN1317041A, the composition percentage range of the composition is not given in the invention; Chinese patent CN 1765803A contains metal nanocomposite powder and natural mineral nano-powder in the invention, the composition percentage range of natural minerals is not given, and the composition is complex; as China Patent CN 1464040A, the particle size in the invention is too large, the dispersion and stability of particles in lubricating oil are not considered, and the composition of the catalyst is not given; Chinese patent CN 1858294A, the content of mineral powder in the invention is too high, the particle size is not given Scope; such as Chinese patent CN 1919954A, the cylinder liner and piston ring side clearance of the railway locomotive in the example, after adding the anti-friction repair agent, the size change is smaller than that without the repair agent, but no repair phenomenon is found

Abstract

The invention relates to a wear repairing lubricating agent composition containing sheet silicate mineral substances and a preparation method thereof. The lubricating agent composition provided by the invention comprises the following components in percent by mass: 10-20 percent of sheet silicate mineral substances, 0.1-5 percent of surface modifying agent, 0.1-5 percent of metal catalytic object, 1-10 percent of performance regulating agent composition and 70-80 percent of base lubricating agent. The preparation method comprises the steps of: mixing and grinding the sheet silicate mineral substances according to the proportion, preferably, sheet silicate mineral substances with granularity D90 of not more than 3mu m; and then adding in a base lubricating agent prepared from a surfactant, the metal catalytic object and the performance regulating agent in different proportions, and grinding. The using method is as follows: 0.2-1 wt percent of the wear repairing lubricating agent composition is added in the traditional lubricating agent system of equipment. The lubricating agent composition provided by the invention has better self-repairing effect and remarkable energy-saving and consumption-reducing effect; and due to a repairing layer formed on the surface through friction, the hardness of a matrix is improved, and the roughness is lowered.

Description

Technical field: [0001] The invention relates to a wear self-repairing lubricant composition containing phyllosilicate minerals and a preparation method thereof. Background technique: [0002] At present, the practical and effective extreme pressure antiwear agents in the field of lubricating oil are substances containing sulfur, phosphorus, and chlorine. Although they have good effects, they will also have adverse effects on the environment. The products of sulfur, phosphorus and chlorine are the development direction of extreme pressure and anti-wear additives in the future. [0003] In recent years, chemical preparations that use natural silicate minerals as a mixture have the functions of reducing friction and dynamic wear and self-repairing. The main problems that need to be solved with chemical preparations that use natural silicate minerals as a lubricant additive are: (1) natural The composition and particle size of silicate minerals determine whether the mixture ha...
