Abstract

The invention relates to an oil agent and a preparation method thereof. The oil agent at least includes fluorine-containing polyether, and the quality of the fluorine-containing polyether is greater than or equal to 45% of the quality of the oil agent; the fluorine-containing polyether is ethylene oxide, [(1 , 1,2,2-tetrafluoroethoxy) methyl] random copolymer of oxirane and propylene oxide, its structural formula is: preparation method of the present invention: starter and strong base are blended, Then heat up to 105~125°C, then add ethylene oxide, [(1,1,2,2-tetrafluoroethoxy)methyl]oxirane and propylene oxide which are mixed uniformly, under protective atmosphere Polymerization reaction to obtain fluorine-containing polyether; then, mix fluorine-containing polyether, phosphate potassium salt and sodium alkylsulfonate uniformly at room temperature, and then add the mixture to mineral oil to obtain oil agent. The invention increases the hydrogen bond in the system, the increase of the hydrogen bond is beneficial to the improvement of the cloud point, and the quality of the oil agent can be maintained while increasing the concentration of the oil agent.

Description

technical field [0001] The invention relates to an oil agent and a preparation method thereof. Background technique [0002] Polyester fiber has many excellent textile properties and wearing properties, and is widely used by people. In the production process of polyester fibers, oils are needed to protect the fibers to a certain extent, so that unnecessary performance damage will occur during the production and processing. [0003] The concentration of conventionally used polyester fiber oil is 10%-15%, and the rest is water. Most of the water evaporates when heated by the hot plate. The evaporation of water will take away a lot of heat and increase the running time of the fiber. time, while increasing energy consumption and polluting the environment. An important factor for the low use concentration is to consider the cloud point of the oil system during use. Within a certain range, the higher the concentration, the lower the temperature at which the cloud point will appe...
