Problems solved by technology

The product decomposed during use will also cause corrosion and deteriorate the cutting fluid, making the product need to be replaced frequently, which not only increases the production cost but also reduces the production efficiency
At the same time, some products also contain substances with strong carcinogenic properties, such as nitrite, chromate, and discharged waste liquid that can make the environment and water eutrophic. Phosphating can also cause red tides, these environmentally unfriendly components are what we need to overcome

Embodiment 1

[0028] The following components of the main composition are by mass percentage:

[0029]

[0030] The synthesis method of the product is to start the stirring of the reaction kettle, and add the following substances in the reaction kettle according to the order:

[0031]

[0032] The finished product can be obtained by compounding. The mixture of straight chain undecane dibasic acid ester and straight chain dodecane dibasic acid ester in the above product system plays an excellent lubricating role in the whole product system and can produce superior The synergistic effect makes the performance indicators of the products meet a higher requirement.

[0033] Product performance testing (according to national GB / T614-2010 standard):

[0034] Take more than 5 parts of synthetic cutting fluid, add 95 parts of water, the detection performance is as follows:

[0035]

[0036]

Abstract

The present invention discloses an antirust metal cutting fluid and a preparation method thereof, and belongs to the field of metallurgical assistant materials. The metal cutting fluid comprises the following components: undecyl diester, dodecyl diester or octadecyl diester and an assistant material. The method comprises that: the components react with diethanolamine and deionized water under a certain conditions to obtain the antirust metal cutting fluid, wherein composite addition of two or more than two straight long chain polycarboxylic acid esters is adopted, such that the performance of the final finished product is more excellent than the performance of the product prepared by using only one straight long chain polycarboxylic acid ester. The product is not added with harmful substances stimulating human body and environment, does not contain organic phosphorus, sulfur, chlorine and other substances, and is prepared by entirely using organic matters with excellent biodegradation performances.

Description

technical field [0001] The invention relates to the field of metallurgical auxiliary material processing, in particular to a cutting fluid with antirust function for cooling or lubricating workpieces such as cutting tools and a preparation method thereof. Background technique [0002] Metal cutting fluid is an important auxiliary material required in the metal processing process. It mainly plays the role of rust prevention, lubrication, cleaning and cooling. At present, cutting fluids at home and abroad are mainly divided into two types: oil-based cutting fluids and water-based cutting fluids, and there is a tendency to transition from oil-based cutting fluids to water-based cutting fluids. Oil-based cutting fluids are commonly referred to as cutting oils, and their lubricating properties Good, but the cooling effect is poor, it will produce smoke under high speed and heavy cutting conditions, and will seriously pollute the environment, and the product is easy to catch fire ...
