Abstract

The invention provides polyisobutene butane diacid amide. The polyisobutene butane diacid amide is characterized in that the molecular structural formula of the polyisobutene butane diacid amide is as shown in specification, and the polyisobutene butane diacid amide provided by the invention has good lubricity, extreme pressure anti-wear property, wear resistance and wear reduction property and can be used for replacing added components such as chlorides, sulfides and phosphides which are harmful for environments in conventional fields. In addition, the polyisobutene butane diacid amide also has good water solubility and enriches the category of conventional lubricating oil additives. Compared with the prior art, minimal quantity lubricating oil prepared by using a method provided by the invention has good lubricity and extreme pressure anti-wear property. A very small quantity of minimal quantity lubricating oil can meet the high-end requirements of metal processing; the damage to environments and workers is reduced; the pollution to environments is minimized. The minimal quantity lubricating oil is particularly applied to a minimal quantity lubrication system and has an obvious effect when being used in ferrous metal processing.

Description

technical field [0001] The invention relates to the technical field of lubrication, in particular to polyisobutene butylene amide, its preparation method and the preparation of micro-quantity lubricant by using the amide. Background technique [0002] Cutting oils, coolants, emulsions and other lubricants used in traditional metal processing lubrication and cooling are used in large quantities, and traditional cutting oils use mineral oil as the base oil, which is not easy to decompose in the natural environment, and most of the additives used are harmful to the human body. Harmful to the environment, it not only wastes resources, but also causes huge pollution of processing sites and the environment. In recent years, the research on micro-cutting technology has made great progress, which has reduced the harm caused by the discharge of a large amount of cutting oil to the environment. However, in order to solve the problem of micro-cutting, excessive amounts of chlorides and...
