Abstract

The invention provides a polyisobutene butenedioic acid salt. The molecular structural formula of the polyisobutene butenedioic acid salt is as shown in the descriptions. The polyisobutene butenedioic acid salt self provided by the invention has good lubricity and extreme pressure antiwear property as well as good water solubility, can be used for replacing added components such as chlorides, sulfides and phosphide unfriendly to environments in conventional fields and enriches the varieties of existing lubricant additives. Compared with the prior art, the micro-cutting liquid prepared by a method provided by the invention has good lubricity and extreme pressure antiwear property; a very small quantity of micro-cutting liquid can meet the high-end requirements on metal processing and is capable of reducing the damage on environments and workers and minimizing the environmental pollution; particularly when the micro-cutting liquid is applied to a minimal quantity lubrication system and is used in ferrous metal processing, the micro-cutting liquid has a remarkable effect.

Description

technical field [0001] The invention relates to the technical field of lubrication, in particular to a polyisobutene succinate, a preparation method thereof, and the preparation of a small amount of cutting fluid by using the salt. 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 chl...
