Totally synthesized cutting fluid adapted for cobalt-containing alloy material and preparation method thereof

Abstract

The invention discloses a total-synthesis type cutting fluid which is applicable for processing cobaltic alloy material, and is composed of the following weight portions of materials: 50-70 parts of water, 8-20 parts of boric acid, 5-18 parts of special amine, 4-20 parts of common alcohol amine, 2-15 parts of synthetic fat, 5-25 parts of antirust, 0.3-1.5 parts of inhibiter, 0.1-5 parts of surfactant, 0-3 parts of addition agent. The preparing method includes the steps of adding the boric acid, the special amine and the common alcohol amine into water; stirring and fully dissolving the solution under the condition of 15-35 DEG C; and then adding in and stirring the synthetic fat, the antirust, the inhibiter, the surfactant and the addition agent fully; adjusting the PH value to 8.5-9.5 after the above substance is dissolved completely. Then the total-synthesis type cutting fluid which is applicable for processing cobaltic alloy material is produced. The total-synthesis type cutting fluid has cobalt precipitation preventing property, can settle fine abrasive dust simultaneously, has high lubricating and antirust performances, is applicable for processing manifold materials, and has long service life and excellent environment protecting performance.

Description

technical field [0001] The invention belongs to the technical field of cutting fluid used in metal processing, and in particular relates to a fully synthetic cutting fluid suitable for processing cobalt-containing alloy materials and a preparation method thereof. Background technique [0002] Fully synthetic cutting fluid is a kind of water-based metal cutting fluid, which does not contain mineral oil at all, and its basic components are water, lubricant, antirust agent, surfactant, etc. The fully synthetic cutting fluid has good cooling effect, clean processing place and stable product performance. It is a kind of metalworking fluid with a wide range of applications. [0003] However, there are still some problems in fully synthetic cutting fluids, such as generally not having the function of inhibiting cobalt precipitation, and cannot be used for processing cobalt-containing alloy materials. Cobalt is usually used as a binder in metal carbides, and is made into materials ...

Problems solved by technology

The discharge of cobalt-containing waste liquid will cause serious pollution to the environment and affect the ecological balance

[0004] In addition, the fully synthetic cutting fluid usually has poor lubricating performance and anti-rust performance, and the finish of the processed workpiece is not enough to meet the requirements of high-precision machining; sodium nitrite is added as an anti-rust agent, which is not conducive to environmental protection; in order to prolong the service life of the product , adding a bactericide that is toxic to the human body and the environment; the fine grinding debris generated during the processing cannot be settled and separated, which shortens the service life of the processing fluid
