Embodiment 1

[0025] Add 8 parts of boric acid, 10 parts of 2-amino-2-methyl-1-propanolamine, and 6 parts of triethanolamine into 60 parts of tap water (hardness not higher than 300PPM), and stir at 30°C for about 30 minutes. It dissolves completely. Then add 12 parts of polyoxyethylene phenyl phosphate (with 6 EOs that are polyoxyethylene chains synthesized by 6 ethylene oxides) item by item; Ester compound antirust agent) 15 parts; 0.3 parts of benzotriazole, 0.1 part of nonylphenol polyoxyethylene (9) ether, fully stirred, and after the above substances were completely dissolved, the pH value was adjusted to 8.5 to obtain The above-mentioned fully synthetic cutting fluid suitable for processing cobalt-containing alloy materials. The above-mentioned parts are parts by mass.

Embodiment 2

[0027] Add 10 parts of boric acid, 15 parts of 2-amino-2-methyl-1-propanolamine, and 5 parts of monoethanolamine into 50 parts of tap water (the hardness of tap water is not higher than 300PPM), and stir for 80 minutes at a temperature of 15°C Left and right to dissolve completely. Then add 5 parts of polyoxyethylene phenyl phosphate (with 6 EOs) item by item; 20 parts of GY-11A antirust agent; 1 part of methyl benzotriazole; C 12 0.1 part of fatty alcohol polyoxyethylene (9) ether, 1 part of n-octanoic acid are fully stirred, and the pH value is adjusted to 8.5 after the above substances are completely dissolved, so as to prepare the cutting fluid suitable for processing cobalt-containing alloy materials. The above-mentioned parts are parts by mass.

Embodiment 3

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 ...
