Problems solved by technology

The disadvantage is that the oil film strength of the liquid lubricant is not high enough. When the boundary lubrication or the equipment stops running, the liquid lubricant returns to the oil pan (or oil tank). At this time, the thickness of the lubricating film on the friction pair is less than 1um (complete liquid lubrication ...

Abstract

The invention relates to a solid-liquid phase composite internal combustion engine oil. According to the theory of solid-liquid phase composite lubrication technology, and aimed at the requirements of the performance, characteristics, working conditions and the like of an internal combustion engine on a lubrication system, the invention provides a technical scheme for the solid-liquid phase composite internal combustion engine oil composition and a preparation method thereof. The components of the oil include solid lubricant material, liquid medium and other auxiliary materials-dispersing agent, oxidation and corrosion inhibitor, detergent additive, internal combustion engine oil complexing agent, defoaming agent and stabilizing and dispersing agent, which are processed into the solid-liquid phase composite internal combustion engine oil with a stable dispersion system by high-speed shearing emulsification, ultrasonic oscillation and sanding dispersion.

Description

1. Technical field: [0001] The invention belongs to the field of lubricants, in particular to a solid-liquid composite internal combustion engine oil. 2. Background technology: [0002] Lubrication is to add lubricant between the frictional contact surfaces in relative motion, so that a lubricating film is formed between the two contacting surfaces, and the dry friction becomes the internal friction between the molecules inside the lubricant, which has achieved reducing friction, reducing wear and extending the use of mechanical equipment purpose of life. [0003] Modern lubricants can be roughly divided into the following categories: [0004] 1. Liquid lubricants: including animal and vegetable oils, mineral oils, synthetic oils, water-based liquids, etc. [0005] 2. Semi-solid lubricant: It is a lubricating material-lubricating grease that is in a semi-fluid state at normal temperature and pressure and has a colloidal structure. [0006] 3. Solid lubricant: it includes ...
