Abstract
The invention belongs to the field of chemical industry, and relates to a thiadiazole-derivative/graphene-containing lubricating oil additive and a preparation method thereof, and a lubricating oil containing the additive. The additive comprises thiadiazole derivatives, graphene, mercaptan, isopropanol, a 30 wt% formaldehyde solution, rare earth chlorides, alkali liquor and phenol substitutes. The nano graphene, which is used as the lubricating oil additive into the lubricating oil, has the functions of protection and repair, and forms a protective film, which can not be penetrated through even by hydrogen atoms, on the inner wall surface of the machine. When the graphene starts to be abraded, the hydrogen atoms jump and repair the crystal lattices, which indicates that the nano-graphene-added lubricating oil can keep permanently effective. The functional groups of the thiadiazole derivatives can form coordinate bonds and hydrogen bonds with graphene, thereby being beneficial to enhancing the dispersity of the graphene in the lubricating oil and the adsorption strength of the lubricating oil and graphene on the metal surface.
Description
Technical field
The invention belongs to chemical field, relate to a kind of lube oil additive that contains thiadiazoles derivative and Graphene, addAdd the preparation method of agent, and contain the lubricating oil of this additive.
Background technology
Energy and environment are two principal themes of economic society sustainable development. For component of machine, fretting wear isCan hardly be avoided. The fretting wear of mechanical part, in bringing a large amount of losses of material and the energy, also can cause very seriousEnvironmental pollution. In lubricating oil, add triboadditives be effectively slow down component of machine fretting wear, reduce energy damageOne of the important technical of consumption. In recent years, the preparation and application technology of nano metal material achieves significant progress, graduallyReach the level that industrialization generates. Nano-metal particle material refers to that physical dimension is the metal ultra micro of 1-100nm levelGrain, be between single atom and solid-state between atom set body. Nearest result of study finds, nano-metal particle material is doneFor lube oil additive has a good application prospect, so many technology and products based on this kind of new material that have been born. ButThe research that at present nano metal composite is applied to lube oil additive then has no report, we have studied stone for this reasonMertenyl Nanometer Copper composite is used for lube oil additive, and have studied the preparation method of this additive material. Graphene isHave the new carbon of monatomic thickness, it has high mechanical strength, good thermal conductivity and fast carrier mobilityRate, for the preparation of the contour performance device of transistor sensor provides raw material. In addition, Graphene has high specific area,It is the base material that preparation nano composite material is fabulous.
Lubricating oil is generally made up of base oil and additive two parts. The quality of base oil is the basic of lubricating oil, addsThe quality and performance of agent is the marrow of lubricating oil, and the quality and performance of additive and the ratio adding directly have influence on lubricating oilServiceability. As a kind of novel nano-material, Graphene is applied to has in lubricating oil that Conventional nano particle do not possessMany advantages. The coefficient of friction of Graphene itself is close to zero, and greasy property is outstanding, and two-dimensional structure physicochemical properties are stable,Have the heat conductivility of superelevation, proportion is little, and easily carries out multiple modification, nanometer additive long-time stability can be solved and askTopic. Therefore, using novel nano-material Graphene as lube oil additive, develop there is good abrasion resistance, high-mechanic energyPower, mechanical surface is there is to the lubricating oil of certain repair function, forms series of new lube product, for lube product byLow side high-end the making contributions of marching toward fast. Although the research of rare earth compound in tribology permeated wear-resistant metal material,The numerous areas such as wear-resistant macromolecule material, wear-resistant ceramic, but at home and abroad only just started as the research of lubricating additive, especiallyIt is the research of oil-soluble organic RE antiwear additive, is the advanced subject of tribochemistry. The research of organic RE antiwear additive is resonableThe application aspect of touching upon all has broad development prospect. China is rare earth big country, from the domestic abundant rare earth resources of development and utilizationUpper theory, has more great theory significance and actual application value.
