Abstract

The invention provides polyisobutene butenedioic acid ester and a preparation method thereof. The chemical structure of the polyisobutene butenedioic acid ester is as shown in specification. The polyisobutene butenedioic acid ester provided by the invention has good lubricity and extreme pressure anti-wear property and can be used for replacing added components such as chlorides, sulfides and phosphides which are harmful for environments in conventional fields. Minimal quantity lubricating oil prepared from the polyisobutene butenedioic acid ester 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.

Description

technical field [0001] The invention relates to the field of lubricating technology, in particular to polyisobutylene butadiene ester and its preparation method and the preparation of micro-quantity lubricating oil by using the polyester. 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...
