Embodiment 1

[0027] Add 0.2mol tetraethyl orthosilicate (TEOS) and 980mL ethanol solution into a 2000ml reaction bottle, mix and place in a constant temperature water bath at 50°C, quickly drop 20mL ammonia water into the mixture under continuous stirring conditions, and make It was uniformly mixed and reacted for 5 hours. After the reaction is completed, 20 g of polyethylene glycol with a molecular weight of 500 is added, ethanol and ammonia water are distilled off, the temperature is raised to 110° C., and the reaction is maintained for 1 hour. After cooling down, add 2 grams of borated diethanolamine, 3 grams of benzotriazole, and then add 500 milliliters of deionized water, and stir evenly to obtain the product.

[0028] In order to illustrate the effectiveness achieved by the technical solution of the present invention, a comparative example is specially prepared, which does not contain nano-silicon oxide in its components, and other components are the same as the examples.

Abstract

The invention discloses an environment-friendly water-based metal machining liquid containing a nano lubricant additive and a preparation method thereof. The composition comprises peptized nano silicon dioxide, polyethylene glycol, diethanolamine boride, benzotriazole and deionized water. The composition does not contain substances such as sodium nitrite, phenol, a chlorine extreme pressure agent, a sulfur extreme pressure agent and a phosphorus extreme pressure agent, accords with the environment-friendly requirement, and has superior lubrification due to introduction of nano silicon oxide.

Description

technical field [0001] The invention relates to metal processing lubrication technology, in particular to an environment-friendly water-based metal cutting fluid containing nano lubricating additives and a preparation method thereof. Background technique [0002] As we all know, cutting fluid is essential in metal cutting. With the development of the mechanical processing industry, people began to vigorously develop advanced manufacturing technology, and at the same time new processes emerged to adapt to the processing of new materials, all of which required new high-performance cutting fluids to meet processing requirements. More importantly, with the enhancement of people's awareness of environmental protection, clean production and green manufacturing have become one of the themes in the development of advanced manufacturing technology. Because cutting fluid occupies and consumes a lot of energy and resources in the process of use, treatment and discharge, the related co...
