A kind of emulsifier and its preparation method and application

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. ...

AI Technical Summary

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
