Problems solved by technology

The Chinese patent application CN1302319A closest to this patent provides a small-molecule water- and oil-repellent compound, which is a water-dispersed type of water-dispersible compound that does not cause large viscosity changes even if it is repeatedly frozen and thawed, and has excellent storage stability. Fluoroalkyl phosphate salt compounds, but the fluorine-containing alkyl group of the compound is an alkyl group with a saturated structure, and its production cost is relatively high

Embodiment 1

[0039] Add 75.24 grams of ethylene glycol and 122.28 grams of triethylamine to a 500-ml 4-neck glass flask equipped with a stirrer, a constant pressure funnel, a condensing reflux tube, and a thermometer, and the temperature rises to 40 degrees. Start to drip 300.5 grams of perfluorohexene C 6 F 12 , the dropwise addition was completed within 1 hour, and the product was washed with water to neutrality after 4 hours of reaction 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 the 4-neck glass flask of 500 milliliters equipped with stirrer, constant pressure funnel, condensation reflux tube, and thermometer, then dropwise add the reaction product of one step, and react for 6 hours at 80 degrees. A pale yellow viscous liquid was obtained, followed by addition of 10 mL of water for hydrolysis at this temperature for 2 hours. Then, the temperature was lowered to room temperature, 20 mL of an equivalent amount of dieth...

Embodiment 2

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

[0045] Add 72.9 grams of dipolyphosphoric acid to the 4-neck glass flask of 500 milliliters equipped with stirrer, constant pressure funnel, condensation reflux tube, and thermometer, then dropwise add the reaction product of one step, and react for 6 hours at 80 degrees. A pale yellow viscous liquid was obtained, followed by addition of 10 mL of water for hydrolysis at this temperature for 2 hours. Then, the temperature was lowered to room temperature, 20 mL of an equal amount of sodium carbonate aqueous ...

Embodiment 3

[0049] Use hydroquinone instead of ethylene glycol, other same as Example 1, obtain perfluorononene phenoxyphosphoric acid diethanolamine salt emulsion, adopt the method of adding inside to process paper, then dry 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 for treating substrates and imparting excellent water and oil repellency to the substrates. In particular, it relates to a low temperature-resistant fluorine-containing olefin-based phosphate-based fluorine-containing water- and oil-repellent agent that can be imparted to paper, wood, leather and other fiber weaving irregular substrates with excellent water and oil repellency without causing other performance changes. . Background technique [0002] At present, it has been known to coat the surface of a substrate with a water-repellent substance with low surface tension for water- and oil-repellent treatment. For example, the substrate is treated with non-hydrophilic waxes; acrylic or vinyl polymer compounds or siloxanes to make the substrate not easily wetted or wetted by water, but the above-mentioned hydrocarbon compounds or siloxanes Can impart non-...
