Problems solved by technology

[0003] Due to the high activity of aluminum and aluminum alloys, the requirements for cutting fluids are higher. Generally, special cutting fluids are required. However, most of the cutting fluids on the market currently use imported phosphorus-containing corrosion inhibitors. This additive contains phosphorus. It is easy to cause the growth of bacteria and reduce the service life of cutting fluid

Embodiment 1

[0053] Synthetic corrosion inhibitors:

[0054] Add 10 parts of organic alcohol amine, 2 parts of petroleum sulfonate, 2 parts of vegetable oleic acid, 1 part of tall oil acid, and 8 parts of boric acid monoethanolamine into the stirring reaction kettle in turn, and then heat it to 100-160 degrees. Then keep it warm for 30-40 minutes, after cooling, add 5 parts of silane coupling agent and 1 part of fluozirconic acid or fluotitanic acid, and stir evenly to obtain the required corrosion inhibitor.

[0055] Preparation of metalworking fluids

[0056] Add 10 parts of base oil, 2 parts of oily lubricant, 8 parts of extreme pressure agent, 4.5 parts of surfactant, 1 part of chelating agent, 3 parts of bactericide, 0.2 parts of defoamer, and 29 parts of corrosion inhibitor in the mixing tank and 42.3 parts of water, and finally obtain a metalworking fluid with a total mass of 100 parts.

[0057] The performance of the cutting fluid is as follows:

Abstract

The invention discloses a metal cutting fluid and a preparation method thereof. The corrosion inhibitor in the metal cutting fluid comprises an organic carboxylic acid amide salt, a silane coupling agent, a hydramine borate, fluozirconic acid or salts thereof/fluotitanic acid or salts thereof, and petroleum sulfonate. The metal cutting fluid has favorable universality, can simultaneously protect ferrous metals and nonferrous metals, can prevent metals from rusting or discoloring in the cutting process or after finishing cutting, has long-term antirust effects on ferrous metals, and has excellent lubricating property, cleaning property and cooling property.

Description

technical field [0001] The invention belongs to the technical field of cutting fluid, and in particular relates to a metal cutting fluid and a preparation method thereof. Background technique [0002] Metal cutting fluid refers to the lubricating and cooling materials used in various processing processes such as cutting, grinding, stamping, rolling and drawing of metals and their alloys. As an important supporting material for machining, cutting fluid mainly plays the role of cooling, lubricating, cleaning and rust prevention. There are many other requirements for cutting fluid in machining process, such as long-term performance, cheapness, versatility and environmental protection performance. With the advancement of modern manufacturing equipment, the continuous emergence of processing technology and processing materials, higher requirements are put forward for the versatility of cutting fluids. [0003] Due to the high activity of aluminum and aluminum alloys, the require...
