Abstract

The invention belongs to the field of metal cutting fluids, and discloses a novel-emulsion-system cutting fluid based on a polyisobutylene succinic anhydride and a preparation method and application of the cutting fluid. The cutting fluid comprises base oil, a polyisobutylene succinic anhydride mixture (the mixture is formed by mixing of three polyisobutylene succinic anhydrides which separately have a molecular weight of 200, 400 and 1000, and the mass ratio of the polyisobutylene succinic anhydride with a molecular weight of 200 to the polyisobutylene succinic anhydride with a molecular weight of 400 to the polyisobutylene succinic anhydride with a molecular weight of 1000 is 2:1:1), a non-ionic surfactant, a pH modifier, a lubricant, an extreme pressure agent, an antirusting agent, a corrosion inhibitor, and a bactericide. According to the invention, the polyisobutylene succinic anhydride mixture is used as a main emulsifier of the cutting fluid for the first time, thus the emulsion system is very stable, stinking and bacterium growth are not easily, and the product service life is very long, wherein the cutting fluid can be used for half a year or more; and the cutting fluid has properties such as excellent antirust properties, lubricating performance and low-foam performance. The cutting fluid properties are excellent, thus the cutting fluid can be used in machining center with high speed precision, especially the cutting fluid has outstanding performance in a non-ferrous metal processing aspect, and the cutting fluid is mainly used for aspects such as electronic product tapping, and deep-hole drilling.

Description

technical field [0001] The invention belongs to the field of metal cutting fluids, and in particular relates to a cutting fluid based on a novel emulsified system of polyisobutenyl succinic anhydride and its preparation method and application. Background technique [0002] Water-based metal cutting fluid came out in the 1940s and developed rapidly due to its low cost and excellent cooling characteristics. So far, water-based metal cutting fluid has been in a dominant position in some metal processing fields. At present, the water-based metalworking fluid system usually uses petroleum sulfonate as the emulsification system, which has disadvantages such as not being environmentally friendly, easy to stink, low production efficiency, and large environmental pollution. At the same time, a series of changes in the future direction of the global environment, health and safety expectations, stricter regulations, etc., make the metalworking fluid industry face many challenges.
