A kind of nano synthetic lubricating oil and preparation method thereof

Abstract

The invention relates to a nanometer synthetic lubricant and a preparation method thereof. The nanometer synthetic lubricant comprises the following raw materials in percentage by weight: 60-90% of a lubricant base oil, 0.1-0.6% of a nanometer material, 3-13% of an antioxidant, 4-16% of a dispersant, 1-5% of a tackifier, and 1.9-5.4% of an anti-wear additive. The nanometer synthetic lubricant is prepared by mixing and refining the lubricant base oil, the nanometer material, the antioxidant, the dispersant, the tackifier, and the anti-wear additive by a high shear emulsion production line. The invention has the following beneficial effects that the nanometer synthetic lubricant is a comprehensive technology which can facilitate the energy conservation, emission reducing, environment protecting and efficiency increasing of internal combustion engines and automobile engines, and in the premise of saving a lot of operation cost, the nanometer synthetic lubricant can advance the achievement of the emission reduction goal which is superior to 'state V emission standards', the level of PM2.5 is reduced in the excellent emission standard, and the high-powered driving fun of users brought by the pressure of a cylinder of the engine is recovered and improved.

Description

technical field [0001] The invention relates to a nanometer synthetic lubricating oil and a preparation method thereof. Background technique [0002] Lubricating oil is a mixture of lubricating oil base oil and various additives. Base oils currently on the market are basically divided into three types, namely mineral oils, semi-synthetic oils and synthetic oils. According to the custom, the base oil extracted from petroleum by physical distillation is called mineral oil (some non-deeply hydrogenated base oil should also be called mineral oil). Synthetic oil, as the name implies, is a base oil obtained through chemical synthesis (most of its components do not directly exist in petroleum). There is no precise definition of synthetic oil and mineral oil, which is commonly known as semi-synthetic oil. API (American Petroleum Institute) divides base oils into five categories, and the third and fourth base oils are usually called synthetic oils. [0003] In fact, the base oil ...
