Embodiment 1

[0039] Add 75.24 grams of ethylene glycol and 122.28 grams of triethylamine to a 500-milliliter 4-neck glass flask equipped with a stirrer, a constant pressure funnel, a condensing reflux tube, and a thermometer. The temperature rises to 40 degrees, and 300.5 grams of triethylamine are added dropwise Perfluorohexene C 6 f 12 , the dropwise addition was completed within 1 hour, and after 4 hours of reaction, the product was washed with water to neutrality to obtain about 321.58 grams of C 6 f 11 OCH 2 CH 2 Oh.

[0040] Add 72.9 grams of dipolyphosphoric acid to a 500-milliliter glass flask equipped with a stirrer, a constant pressure funnel, a condensing reflux tube, and a thermometer, then add the reaction product of one step dropwise, and react at 80 degrees for 6 hours. A light yellow viscous liquid was obtained, and then 10 mL of water was added to carry out hydrolysis at this temperature for 2 hours. After cooling down to room temperature, 20 mL of an aqueous solutio...

Embodiment 2

[0044] Add 75.24 grams of ethylene glycol and 122.28 grams of triethylamine to a 500-milliliter 4-necked glass flask equipped with a stirrer, a constant pressure funnel, a condensing reflux tube, and a thermometer. The temperature rises to 40 degrees, and 450.0 grams of triethylamine are added dropwise. Perfluorononene C 9 f 18 , the dropwise addition was completed within 1 hour, and after 4 hours of reaction, the product was washed with water to neutrality to obtain about 470.1 grams of C 9 f 18 OCH 2 CH 2 Oh.

[0045] Add 72.9 grams of dipolyphosphoric acid to a 500-milliliter glass flask equipped with a stirrer, a constant pressure funnel, a condensing reflux tube, and a thermometer, then add the reaction product of one step dropwise, and react at 80 degrees for 6 hours. A light yellow viscous liquid was obtained, and then 10 mL of water was added to carry out hydrolysis at this temperature for 2 hours. Then it was lowered to room temperature, 20 mL of aqueous sodium ...

Embodiment 3

[0049] Substitute hydroquinone for ethylene glycol, and the others are the same as Example 1 to obtain a perfluorononene phenoxyphosphate diethanolamine salt emulsion. The paper is treated with the method of internal addition, and then dried at 120 degrees. The application results are shown in the table 1.

Abstract

There is provided a phosphas agent with alkenes base that contains fluorine. The agent can resist aqua and oils, the preparation and the application of the agent is also disclosed in the invention. The general formula of the phosphas is [RfQ]m[OH]n[Y+O-]kP=O. While in the formula, Rf stands for perfluoro side chain alkenes base; Q stands for divalent organic group; Y+ stands for (N+HR1R2R3) or base metal iron, of which R1, R2, R3 stand for H atom or -CH2CH2OH (m= integer from 1-3, n=integer from 0-2, k=integer form 0-2, m+n+k=3). The invention can assign the base material excellent quality of resisting aqua and oils. It has no special restriction to the base materials but it's preferable to use base materials which have irregular fiber tissues such as paper, leather and wood.

Description

technical field [0001] The invention belongs to the field of surfactants, and relates to a fluorine-containing surfactant used for substrate treatment and endowing the substrate with excellent water and oil repellency. In particular, it relates to a fluorine-containing olefin-based phosphate-based fluorine-containing water- and oil-repellent agent capable of imparting excellent water and oil repellency to paper, wood, leather and other substrates with irregular fiber weaving without causing other performance changes. . Background technique [0002] At present, it is already known to use a water-repellent substance with low surface tension to coat the surface of the substrate for water-repellent and oil-repellent treatment. For example, non-hydrophilic waxes; acrylic or vinyl polymers or siloxanes are used to treat the substrate to make it difficult to be wetted or infiltrated by water, but the above-mentioned hydrocarbons or siloxanes It can make the substrate non-hydrophi...
