Embodiment 1-3 and comparative example 1-6

[0025] 12 parts of Gemini surfactant (manufacturer: Ningbo Dongfang Yongning Chemical Technology Co., Ltd. specific name: amphoteric Gemini phosphate surfactant), the structure of the Gemini surfactant is: , wherein: R3, R4 are heptadecyl.

[0026] The preparation method of high molecular weight alkanol phosphate ester is as follows: the molar ratio of oleyl alcohol polyoxyethylene ether (C16 primary alcohol polyoxyethylene ether) to phosphorus pentoxide is controlled at 3.5:1, and the reaction temperature is controlled at 62°C. The time was controlled at 5 hours, phosphorus pentoxide was added into the reaction vessel in 4 times, and nitrogen protection was used during the reaction. The preparation of the oleyl alcohol polyoxyethylene ether adopts mixed C14 primary alcohol, C16 primary alcohol, and oleyl alcohol molar ratio of 1:1:1 as raw materials, and prepares mixed fatty alcohol polyoxyethylene ether by addition of ethylene oxide, wherein The molar ratio of EO to fatty ...

Abstract

The invention provides a preparation method of an antistatic agent. The antistatic agent is prepared from raw materials including, by weight percentage, 5-12% of Gemini surfactant, 2-4% of high-molecular-weight chain alkyl alcohol phosphate, 2-4% of low-molecular-weight chain alkyl alcohol phosphate, 0.5-2% of chain alkyl alcohol polyphosphate and 1-8% of polyester. The prepared antistatic agent is good in water solubility, stable in prepared products, low in foaming properties, high in heat resistance and acid-base resistance and good in antistatic effects.

Description

technical field [0001] The invention belongs to the technical field of textile material production, and in particular relates to a preparation method of an antistatic agent. Background technique [0002] With the rapid development of synthetic fibers, the proportion in textiles is increasing, and its status is becoming more and more important. Because synthetic fibers have the characteristics of low hygroscopicity, poor electrical conductivity, and high friction coefficient, the electrostatic problems and their hazards generated in the process of manufacturing, processing and consumption are constantly increasing. During the production of textiles, static electricity not only causes fibers to entangle and fly, but also causes machine parts to behave abnormally, making processing difficult. During the use of clothing, static electricity makes clothing easy to stain and stick to each other, and even generates electric sparks, which seriously affects the appearance and comfort...
