Problems solved by technology

[0003] At present, the semi-synthetic water-soluble cutting fluids on the market are easy to corrode workpieces, volatilize, and decompose easily, which is very unfavorable to the health of operators who have been in contact with the cutting fluid for a long time, and the waste water is not easy to treat. It is necessary to increase oil-water separation equipment and entrust environmental protection companies to recycle.
In addition, the speed S and process flow F of the existing cutting fluid cannot meet the needs of processing capacity
[0004] Although the traditional fully synthetic cutting fluid has certain advantages in cleaning and heat dissipation, it has poor anti-rust and lubricating properties
Although the microemulsion cutting fluid combines the advantages of fully synthetic cutting fluid and emulsified oil, there are a large amount of lipophilic and hydrophilic surfactants in the preparation process, resulting in too much foam in the diluent, which affects the processing
Although emulsified oil has excellent lubricating and anti-rust performance, its service life is short

preparation example Construction

[0057] The second aspect of the present invention provides a method for preparing a fully synthetic cutting fluid, the steps comprising:

[0058] (1) Weigh triethanolamine and its derivatives into water, stir until uniform, and heat to 35-50°C;

[0059] (2) Add antirust agent and oleic acid to the mixture of step (1) while stirring, and then add Swire oil and glycerin;

[0060] (3) Add the antibacterial agent to the mixture in step (2) and stir evenly, after cooling to room temperature, the material can be discharged.

Embodiment 1

[0064] Example 1 provides a fully synthetic cutting fluid, including the following components in parts by weight: 5 parts of triethanolamine and its derivatives, 3 parts of antirust agent, 1 part of sage oil, 2 parts of glycerin, and 1 part of oleic acid , 0.5 part of antibacterial agent, 40 parts of water.

[0065] The triethanolamine and its derivatives are obtained by compounding triethanolamine and triethanolamine borate at a weight ratio of 2.5:1.

[0066] Described antirust agent is the mixture of isooctanoic acid, sebacic acid, terpolymeric acid, sulfonate, wherein, the weight ratio of described isooctanoic acid, sebacic acid, ternary polycarboxylate, sulfonate is 4 : 1:1:1; the sulfonate is obtained by compounding dodecylbenzenesulfonic acid amine and piperazine-1,4-diethanesulfonic acid in a weight ratio of 6.5:1.

[0067] The Swire oil was purchased from Xingtai Xinlanxing Technology Co., Ltd.

[0068] The oleic acid was purchased from Shandong Yangxin Xingye Oleoc...

Abstract

The invention relates to the technical field of metal cutting machining lubrication, in particular to a fully synthetic cutting fluid. A fully synthetic cutting fluid includes the following components: triethanolamine and its derivatives, antirust agent, ancient oil, glycerin, oleic acid, antibacterial agent, and water. The cutting fluid provided by the invention has good antirust performance, lubricating performance and cleaning performance during use, is not suitable for spoilage, can maintain clarity and transparency during use, has good stability, is not easy to decompose at high temperature, and has a long indoor storage period. In addition, the product of the present invention can be widely used for rust prevention between steel materials, cast iron, mechanical parts, alloy steel product components and materials. The rust prevention period is long, and it does not contain harmful substances such as chlorides and phenols. Skin burns, in line with environmental protection requirements.

Description

technical field [0001] The invention belongs to the technical field of metal cutting machining lubrication, and more specifically, the invention relates to a fully synthetic cutting fluid. Background technique [0002] Cutting fluid is an industrial liquid used in metal cutting and grinding processes to cool and lubricate cutting tools and workpieces. It is composed of a variety of functional additives through scientific compounding. As an important auxiliary supporting material for metal cutting, metal cutting fluid can prolong the service life of tools and abrasives, improve the finish of workpieces, and reduce cutting and grinding forces. Its main functions include cooling, lubrication, rust prevention and cleaning four aspects. Generally used cutting fluids are mainly oil-based and water-based. In recent years, water-based cutting fluids have remarkable characteristics in terms of cooling, cleaning, rust resistance, and lubricity, and have been more and more widely used...
