Problems solved by technology

[0003] At present, there are many types of knitting machine oils in the market, but some knitting machine oil products cannot be emulsified and dispersed well in cold water. When cleaning equipment during the oil change period, there are always oil stains on the surface of the equipment that are not clean. This will lead to pinhole blockage, weaving needle leakage, and affect the knitting efficiency; at the same time, during the high-speed operation of the textile machinery, it is inevitable that the fabric will be splashed with knitting machine oil. In the later cleaning process, if the selected knitting machine oil has insufficient cleaning performance, Failure to effectively remove oil stains may lead to uneven dyeing of the fabric and reduce efficiency, and may leave yellow spots or oily smell on the finished fabric, which is difficult to remove

Embodiment 1

[0021] Raw material components: oleic acid monoglyceride 40g, C 12 Acid polyoxyethylene (3) ester 360g, C 12～14 Alcohol polyoxyethylene (9) ether 90g, C 12～14 Alcohol polyoxyethylene (3) ether sodium sulfate 10g and nonylphenol polyoxyethylene (5) ether 30g.

[0022] Preparation method: Put the above-mentioned raw materials into the blending kettle, start heating and stirring, wait until the temperature rises to 60°C, keep warm for about 30 minutes, observe the appearance of the system, after it is clear and transparent, filter at 30°C to remove possible mechanical impurities, Samples were then taken for emulsifier stability evaluation.

[0023] Preparation of knitting machine oil: compound the above-mentioned emulsifier and mineral oil for knitting machine oil, take 100g of the above-mentioned emulsifier, add 1000g of mineral oil 70N, 0.5g of benzotriazole, 0.5g of 2,6-di-tert-butyl-4- For methyl phenol, stir at 60°C for 30 minutes. After the system is clear and transparen...

Embodiment 2

[0030] The basic steps are the same as in Example 1, the difference is that C 12 ~ 14 Alcohol polyoxyethylene (3) ether instead of C 12 Acid polyoxyethylene (3) ester.

Embodiment 3

[0032] The basic steps are the same as in Example 2, except that nonylphenol polyoxyethylene (4) ether is used instead of nonylphenol polyoxyethylene (5) ether.

Abstract

The invention discloses an emulsifying agent as well as a preparation method and application thereof. The emulsifying agent is prepared from polyol fatty acid ester, surface active agents with different HLB (Hydrophile Lipophile Balance) values and alkylphenol polyoxyethylene ether; the preparation method comprises the steps of uniformly mixing raw materials, raising the temperature to 60 DEG C, stirring, then cooling to 30 DEG C, filtering and removing impurities. The emulsifying agent is applied to knitting machine oil, has the advantages that the emulsifying agent is colorless, odorless and transparent oily liquid, has no layering and sediment phenomena after long-term storage, and is suitable for emulsifying base oil with the viscosity range being 5 to 30mm<2> / s at 40 DEG C; meanwhile, the preparation process of the emulsifying agent is simple, environment-friendly and free of pollution; in addition, the knitting machine oil obtained by compounding the emulsifying agent with the base oil can be quickly emulsified and dispersed in cold water, emulsion microscopic particle size distribution is uniform, after being stored at room temperature for 24 hours, emulsion has no layering and floating oil phenomena, and the emulsifying agent has an excellent cleaning effect on knitting machine oil draining period equipment or fabric with splashes of oil.

Description

technical field [0001] The invention belongs to the field of industrial lubricating oil, in particular to an emulsifier, a preparation method and application thereof. Background technique [0002] In the textile industry, the knitting machine oil emulsifier is compounded with base oils of different viscosities and types, and then used for the lubrication of knitting needles, sinkers and other parts of textile machinery. With the rapid development of the textile industry and the continuous improvement of textile efficiency, textile quality and textile materials, the textile industry has put forward higher requirements for knitting lubricants. The primary purpose is that modern knitting machine oil must have excellent cleaning performance. Other application properties such as lubricating performance, anti-oxidation performance, and corrosion resistance performance can be met by introducing functional additives during the compounding process of general knitting machine oil. ...
