Problems solved by technology

In the process of engine manufacturing, many metals are cut with non-water-soluble lubricating medium, and the surface of the machined parts will remain non-water-soluble oily medium, which needs to be cleaned with a large amount of cleaning agent, which wastes resources and increases the difficulty of operation.

preparation example Construction

[0025] For the preparation of mixed surfactants, in this example, two lauryl alcohol polyoxyethylene ethers with different HLB values ​​are selected and mixed in different proportions to obtain lauryl alcohol polyoxyethylene ethers with an HLB value between 10 and 12. ether.

[0026] Among them, the mixing principle of two lauryl alcohol polyoxyethylene ethers with different HLB values ​​is proportioned according to the following formula:

[0027] HLB 0 = W a × H L B a + W b × H L B b W a + W b

[0028] Where: HLB 0 - The HLB value of the mixed surfactant is between 10 and 12;

[...

Embodiment 1

[0035] Mix 5 parts of lauryl alcohol polyoxyethylene ether with HLB=5 and 5 parts of lauryl alcohol polyoxyethylene ether with HLB=15 to obtain a mixed surfactant of HLB=10, add it to the machine oil in a mass percentage of 5% In, a water-soluble mechanical oil is obtained.

Embodiment 2

[0037] Mix 8 parts of lauryl alcohol polyoxyethylene ether with HLB=10 and 10 parts of lauryl alcohol polyoxyethylene ether with HLB=12 to obtain a mixed surfactant of HLB=11.11, which is added to the machine oil in a mass percentage of 4.5% In, obtain a kind of water-soluble machine oil machine oil.

Abstract

The invention belongs to the technical field of lubricating oil for metal processing and discloses water-soluble machine oil. The water-soluble machine oil is prepared from, by mass, 4%-6% of mixed surfactant, and the balance machine oil. The mixed surfactant is formed by mixing two kinds of dodecyl polyoxyethylene ether with different HLB values. The HLB value of the mixed surfactant ranges from 10 to 12. The mixed surfactant formed by mixing the two kinds of dodecyl polyoxyethylene ether is added to the common machine oil, when the water-soluble machine oil is applied to an engine manufacturing industry, cleaning efficiency can be improved, the cleaning temperature can be reduced, the use level of a cleaning agent can be reduced, the cleaning cost can be reduced, and emission pollution can be reduced.

Description

technical field [0001] The invention belongs to the technical field of lubricating oil for metal processing, and relates to a water-soluble mechanical oil. Background technique [0002] Lauryl alcohol polyoxyethylene ether is a kind of surfactant, which is synthesized by lauryl alcohol and ethylene oxide under the action of a catalyst. Each molecule of lauryl alcohol is a lipophilic group, and polyoxyethylene ether is The hydrophilic group is thus an amphiphilic molecule with both hydrophilic and lipophilic functions. [0003] Lauryl alcohol polyoxyethylene ether is used in the textile industry. It is used as a leveling agent in the printing and dyeing process of textiles to make the dyes evenly distributed on the surface of textiles. In the weaving process of textiles, lauryl alcohol polyoxyethylene ether can form a lubricating film on the surface of textile fibers to prevent fibers from breaking due to friction. [0004] Lauryl alcohol polyoxyethylene ether is used in pe...
