Abstract
The invention discloses a nanoscale lubricating oil additive and application thereof. The additive is prepared from pure tungsten powder and selenium powder as raw materials, and a WSe2 nano material is prepared by using the solid-phase reaction method through mixing, ball-milling, tabletting and calcining processes. The nano material as a lubricating oil additive is added into industrial lubricating base oil, and industrial lubricating oil with good stability, load resistance and self-repairing capability can be obtained through ultrasonic dispersion. The additive can be applied to various kinds of industrial lubricating oil, has excellent serviceability of high-temperature resistance and corrosion resistance, can obviously reduce friction and alleviate the corrosion of a machine, has pollution-free in-situ dynamic protection and repairing effects on equipment or parts, effectively prolongs the service life of the machine, the equipment and the parts, also has the advantages of fewer material components, simple preparation process, low cost, high yield and the like, not only is economical but also is practical and is applicable to popularization and application.
Description
Technical field: the present invention relates to a kind of novel nano-material, particularly relate to a kind of novel nano-material that is used to prepare the nano level lubricating oil additive, the invention still further relates to the application of this nano material.
Technical background: in recent years, flourish along with aerospace, communications and transportation and microelectronic system, the volume of holding of all kinds of vehicles, machinery, electronic component grows continuously and fast, and the lubricating oil consumption that makes China is more than 4,000,000 tPa, and the oil dope amount then needs more than 200,000 tPa.The price of fuel oil and lubricating oil that causes in short supply of petroleum resources goes up again and again yet at present.Fiery transportation and petroleum resources in short supply will bring new opportunities and challenges for the development in China lubricant market.In the face of the rapid growth of vehicles demand and the enhancing of people's environmental protection consciousness, the conventional lubrication additive is difficult to satisfy the requirement of present hi-tech and highly selective.How to improve lubricating oil (fat) performance, prolong each parts work-ing life, reducing use cost, reducing lubricated product is that pendulum is badly in need of the technical barrier that solves in face of scientific research personnel and user to the harm of environment.
Summary of the invention: the object of the present invention is to provide a kind of nano level lubricating oil additive, another object of the present invention is this Application of Additives, mainly be in order to solve the performance that how to improve lubricating oil (fat), to prolong each parts work-ing life, reduce use cost, reduce the harm that lubricated product brings environment, thereby satisfy the problem of present hi-tech and highly selective requirement.
The present invention is to be starting material with pure metal tungsten powder (W) and selenium powder (Se), adopt solid reaction process to prepare the WSe2 nano material that mean diameter is lower than 20nm through mixing and ball milling, compressing tablet, calcining process, this nano material is added in the industrial lubrication base oil as lubricating oil additive, through ultra-sonic dispersion, obtain a kind of have anti-load and the good industrial lubricant of self-healing properties.
The present invention is owing to take tungsten powder and selenium powder to prepare nano material, after material becomes more meticulous, because superfine crystal grain, the central atom and the nano material itself thereof that are in crystal boundary and intragranular defective in a large number have characteristics such as quantum size effect, small-size effect, surface interface effect, macroscopic quantum effect and low melting point, have high diffusibility and self-diffusion ability (than high tens orders of magnitude of body phase material), very easily form pervious course and diffusion layer, show " original position tribo-chemistry effect " with splendid abrasion resistance in the metallic surface.This nano material is this performance of nano level lubricating oil additive, in the situation that solves at wear-resistant (AW) and the long-term P of dependence of extreme pressure (EP) additive molecule design, Cl isoreactivity element, showed fine application prospect aspect corrosion that the body metal is caused in solution and the environmental problem of bringing.Nano level lubricating oil additive of the present invention may be used in the various industrial lubricants; make it have more excellent high temperature resistant, corrosion resistant use properties; can significantly reduce friction; alleviate the corrosion of machine; have free of contamination original position dynamic protection and repair for equipment or component; effectively improve the work-ing life of machine, equipment or component, solve various difficult problems that cause because of frictional wear, lubricated maintenance or maintenance.And nano lubricating oil additive of the present invention is homogeneous, transparent liquid, overcome defectives such as existing opaque, the instability of conventional lubrication oil additive.Have also that the new component of material is few, preparation technology is simple, cost low-yield height, not only economy but also practicality, advantage such as suit to apply.
Embodiment: nano level lubricating oil additive of the present invention is to be starting material with high pure metal tungsten powder (W) and selenium powder (Se); by tungsten powder and selenium powder proportion is that mol ratio is mixed at 1: 3; under argon shield, pack in the ball mill; mixing and ball milling 5h in planetary high-energy ball mill; take out mixed powder; 100N pressure depresses to the oblate column compressing tablet that diameter is 10mm on omnipotent tabletting machine; put into the CVD tube furnace then; under argon shield; temperature rise rate with 15 ℃/min is calcined; be warming up to 750 ℃, insulation 1h, obtaining the grey black WSe2 nanometer powder that mean diameter is lower than 20nm is nano level lubricating oil additive of the present invention.
With 0.5-5% of the present invention, microemulsified tensio-active agent 1-10%, industrial foundation oil 8-85% mix, and through ultra-sonic dispersion 5h, obtain the uniform and stable industrial lubricant that contains nanometer additive at last.Our experiments show that: nano level lubricating oil additive of the present invention is in the application of industrial lubricant, to lubricated maintenance machinery equipment, alleviate mechanical erosion, reduce mechanical friction wearing and tearing, equipment original position dynamic protection and reparation, the aspect in work-ing life that effectively improves machinery equipment or component has good effect.
