Description

Technical Field

[0001] The invention relates to a lubricating oil composition with a polymer compound as a base material, and in particular to an emulsified polyester industrial yarn oil and a preparation method thereof. Background Art

[0002] Synthetic fiber is a high molecular weight organic compound extracted from natural organic matter such as coal, oil, and natural gas. It does not contain smooth fat substances, has a large friction coefficient, poor conductivity, and low hygroscopicity. Therefore, it is easy to scatter and slide during spinning and subsequent processing, resulting in fuzz and waste. Therefore, a layer of oil that can play a role in smoothing is needed on the surface of synthetic fibers to ensure smooth production.

[0003] Modern spinning oil plays an important role in improving fiber quality, directly affecting the smooth spinning and the quality of post-drafting. Modern high-speed spinning equipment requires spinning oil to have good stability, smoothness, antistatic properties, adsorption wettability, low viscosity, low interfacial tension and less foam. If the oil is used directly on spinning, problems such as uneven oiling and poor adsorption and wetting properties usually occur. In order to make the oil smoothly and evenly coated on the surface of the silk, we need to emulsify and dilute the oil to ensure the smooth progress of subsequent stretching, deformation, winding and other work.

[0004] The characteristic of the emulsion system is that two immiscible liquids can form a stable dispersion system through emulsification. The dispersed liquid (dispersed phase) is dispersed in another continuous liquid (continuous phase) in the form of small liquid droplets, and the diameter of the droplets contained is mostly distributed between 100 nanometers and 10 microns. The emulsion types are: water-in-oil emulsion is represented by O / W, its dispersed phase is oil, and the continuous phase is water; oil-in-water emulsion is represented by W / O, its dispersed phase is water, and the continuous phase is oil.

[0005] Selecting multiple emulsifiers, smoothing agents and antistatic agents to compound and emulsify into microemulsions to prepare oils can better meet actual needs. Since the ambient temperature of the spinning oil can sometimes reach 100℃ to 300℃, emulsifiers with low boiling points are usually not selected as raw materials for preparing emulsions. Usually, two or more emulsifiers are selected to compound into composite emulsifiers to prepare microemulsions. Summary of the invention
