Problems solved by technology

[0002] The current fluorine-based hydrophobic and oleophobic agents exist in two types: solvent form or water dispersion form. Among them, the solvent-type fluorine-based hydrophobic and oleophobic agents have problems such as environmental pollution, fire hazards, and toxicity. Therefore, in recent years, It has been gradually replaced by the water dispersion type fluorine hydrophobic and oleophobic agent system; however, to manufacture the water dispersion liquid fluorine hydrophobic and oleophobic agent must add surfactants and appropriate co-surfactants to stabilize the fluorophore dispersed in water. Fluorine-containing polymers, but the current water-based fluorine-based hydrophobic and oleophobic products are limited by technology, and all have problems such as poor emulsion stability, large changes over time, and narrow product application ranges, so that they must be used in various textile or The characteristics of leather products are tailored to produce specific fluorine hydrophobic and oleophobic agents; at the same time, water-based series products are not washable and have poor physical properties, which is also one of the main reasons why such products cannot be widely used

Embodiment 1

[0062] Add 24.75 grams of trimethylol propane (Trimethylol propane) into a 2L glass reaction vessel equipped with a stirrer, a vacuum motor, a thermometer and a condenser, etc., and release the vacuum with nitrogen after evacuating for 30 minutes; add 123.75 grams of IPDI, Heat to 85-90°C for 2 hours, then start measuring NCO%, add 231 grams of CF when NCO% reaches 16-18% 3 (CF 2 ) 7 (CH 2 ) 2 OH, heat up to 95°C for constant temperature reaction, start to measure NCO% after constant temperature for 4 hours, add 325.5 grams of butanone when NCO% reaches 1.5-2.0%, and keep the temperature at 70±3°C for 10 hours; cool down to 50±3°C, Add 15 grams of butanone oxime (Butanone oxime) and keep the temperature for 1 hour, then add 600 grams of butanone and 150 grams of butyl acetate and stir for 30 minutes; the polymerization reaction produces a polymer dispersion with a weight of 1470 grams and a solid content of 24.1%. .

Embodiment 2

[0064] Add 24.5 grams of trimethyl alcohol propane into a 2L glass reaction vessel equipped with a stirrer, vacuum motor, thermometer and condenser, etc., and release the vacuum with nitrogen after evacuating for 30 minutes; add 29.5 grams of HDI and 85 grams of IPDI, Heat to 85-90°C, start to measure NCO% after constant temperature for 2 hours, add 231 grams of CF when NCO% reaches 16-18% 3 (CF 2 ) 7 (CH 2 ) 2 OH, heat up to 95°C for constant temperature reaction, start to measure NCO% after constant temperature for 4 hours, add 320 grams of butanone when NCO% reaches 1.5-2.0%, and keep the temperature at 70±3°C for 10 hours; cool down to 50±3°C, Add 15 grams of butanone oxime and keep the temperature for 1 hour, then add 400 grams of butanone and 350 grams of butyl acetate, and stir for 30 minutes; the polymerization reaction produces a polymer dispersion with a weight of 1455 grams and a solid content of 24.3%.

Embodiment 3

[0066] Required raw material, weight and polymerization method are identical with embodiment one, but change the raw material CF of second-stage polymerization reaction 3 (CF 2 ) 7 (CH 2 ) 2 OH is 105 grams of CF 3 (CF 2 ) 7 (CH 2 ) 2 OH with 112.5 g of CF 3 (CF 2 ) 6 (CH 2 ) 2 OH mixed. The polymerization yielded a polymer dispersion weighing 1456.5 grams and having a solids content of 24.1%.

Abstract

A fluorine hydrophobic-lipophobic agent of solvent type is prepared form 20-50% W / W blocked polyfluoroazyl ethyl formate compound and 50-80 % W / W solvent as the composition of blocked polyfluoroazyl ethyl formate compound includes fluoroalcohol compound, diisocyanate or polyisocyanate compound, bridging agent and blocking agent. The population-polymerization method is applied to synthesize blocked polyfluoroazyl ethyl formate compound.

Description

technical field [0001] The invention relates to a solvent-type fluorine-based hydrophobic and oil-repellent agent, its preparation method and its application on fabrics and leathers. Background technique [0002] The current fluorine-based hydrophobic and oleophobic agents exist in two types: solvent form or water dispersion form. Among them, the solvent-type fluorine-based hydrophobic and oleophobic agents have problems such as environmental pollution, fire hazards, and toxicity. Therefore, in recent years, It has been gradually replaced by the water dispersion type fluorine hydrophobic and oleophobic agent system; however, to manufacture the water dispersion liquid fluorine hydrophobic and oleophobic agent must add surfactants and appropriate co-surfactants to stabilize the fluorophore dispersed in water.
