The invention provides a lubricant with good stability, good effect, uniform lubricating oil concentration, small friction coefficient and low price; by adding a certain additive, the lubricating oil has stable properties, does not influence the using effect of the lubricating oil, and can effectively improve the lubricating quality of the lubricating oil.
Description
Technical Field
The invention relates to a lubricant with good stability, and belongs to the technical field of fine chemical engineering.
Background
The lubricating oil is divided into four categories of animal oil, vegetable oil, petroleum lubricating oil and synthetic lubricating oil according to the source. The amount of petroleum oil used is more than 90% of the total amount, so the oil is often referred to as petroleum oil. The friction between the surfaces of moving parts is reduced, and the cooling, sealing, corrosion prevention, rust prevention, insulation, power transmission, impurity cleaning and the like effects are achieved on machine equipment. Mainly takes lubricating oil fraction and residual oil fraction from a crude oil distillation unit as raw materials. The most important properties of lubricating oils are viscosity, oxidation stability and lubricity, which are closely related to the composition of the lubricating oil fraction. Viscosity is an important quality indicator reflecting the fluidity of lubricating oils. Different conditions of use have different viscosity requirements. High viscosity lubricating oils are used for heavy duty and low speed machines. The oxidation stability indicates the oxidation resistance of the oil in the use environment due to the temperature, oxygen in the air and metal catalysis. After oxidation of the oil, depending on the conditions of use, fine, asphaltene-based carbon-like substances, viscous lacquer-like substances or films, or viscous water-containing substances are formed, which reduce or lose their properties of use. The lubricating oil additive mainly comprises an antioxidant, a metal deactivator, an extreme pressure antiwear agent, a friction modifier (also called oiliness agent), a detergent dispersant, a foam inhibitor, an antirust agent, an antioxidant preservative, a flow point modifier, a viscosity index improver, an anti-emulsion agent and the like according to functions. The additives sold in the market are generally composite products of the above single additives, and the difference is that the components of the single additives are different and the proportion of the single additives in the composite additives is different.
Disclosure of Invention
The invention aims to provide a lubricant with good stability.
The technical scheme of the invention comprises the following steps: the lubricating oil is prepared from the following raw materials in parts by weight: 700-1000 parts of neutral base oil, 1-5 parts of phosphoric acid, 4-6 parts of a viscosity index improver, 5-12 parts of a silane coupling agent, 20-35 parts of petroleum ether, 1-4 parts of benzyl alcohol, 4-10 parts of engine oil, 5-10 parts of zinc primary and secondary alkyl thiophosphoryl salt, 1-5 parts of sulfurized isobutylene, 1-5 parts of a stabilizer, 10-15 parts of an extreme pressure antiwear agent, 5-8 parts of nitric acid, 2-4 parts of glycerol acrylate and 20-35 parts of water.
The invention has the beneficial effects that: the invention provides a lubricant with good stability, good effect, uniform lubricating oil concentration, small friction coefficient and low price; by adding a certain additive, the lubricating oil has stable properties, does not influence the using effect of the lubricating oil, and can effectively improve the lubricating quality of the lubricating oil.
