Embodiment 1

[0084] (1) p -Nafluorobutylaniline

[0085] Add 3.44 g of p-bromoaniline, 5 g of copper powder (catalyst) and 100 ml of dimethyl sulfoxide (DMSO) into a 250 ml three-necked flask equipped with a magnetic stirring bar, a thermometer and a condenser, and heat to 60 °C with stirring. Then 9 g of nonafluoroiodobutane was dissolved in 25 ml of DMSO and added to a constant pressure dropping funnel, and slowly dropped into a three-necked flask. After the nonafluoroiodobutane solution was added dropwise, the reaction system was heated to 120 °C and refluxed for 24 h. The reaction system was cooled to room temperature, and the reaction was poured into a 500 ml beaker, and 100 ml of deionized water and 200 ml of anhydrous ether were added at the same time, the layers were stirred, and the copper powder was filtered off. Pour the filtrate into a 500 ml separatory funnel to separate the organic layer and wash it with deionized water (30 ml x 3 times), dry over anhydrous magnesium sulfat...

[0113] (1) p -Heptadecafluorooctylaniline

[0114] Add 3.45 g of p-bromoaniline, 5.15 g of copper powder (catalyst) and 100 ml of dimethyl sulfoxide into a 250 ml three-neck flask equipped with a magnetic stirring bar, a thermometer and a condenser, and heat to 60 °C with stirring. Then 9.21 g of heptadecafluoroiodoctane was dissolved in 25 ml of dimethyl sulfoxide and added to a constant pressure dropping funnel, and slowly dropped into a three-necked flask. After the nonafluoroiodobutane solution was added dropwise, the temperature of the reaction system was raised to 115° C. and refluxed for 12 hours. The reaction system was cooled to room temperature, and the reaction was poured into a 500 ml beaker, 100 ml of deionized water and 200 ml of anhydrous ether were added at the same time, the layers were stirred, and the copper powder was filtered off. Pour the filtrate into a 500 ml separatory funnel to separate the organic layer and wash with deionized water (30 ml × 3 time...

Abstract

The invention discloses intelligent surface-hydrophilicity-and-hydrophobicity-convertible fabric finishing liquid and a preparation method thereof. An effective component of the finishing liquid provided by the invention is a perfluoroalkyl azophenyl acrylate copolymer. Perfluoroalkyl azophenol is used as an initial raw material, and esterification reaction is performed on the perfluoroalkyl azophenol and acryloyl chloride, thus obtaining a perfluoroalkyl azophenyl-containing acrylate monomer; the perfluoroalkyl azophenyl-containing acrylate monomer, hydroxyethyl methylacrylate and butyl acrylate are polymerized through an emulsion, thus preparing a perfluoroalkyl azophenyl-containing acrylate copolymer emulsion. During emulsion polymerization, the use amount of an initiator is increased, so that an obtained copolymer is low in degree of polymerization, a copolymer molecular main chain is relatively short, and the degree of twisting of a molecular chain is small; therefore, the molecular isomerism capacity of lateral radical azophenyl is high, and conversion of surface hydrophilicity and hydrophobicity is facilitated. An intelligent water repellent finishing agent provided by the invention is mild in preparation reaction conditions, simple in preparation process and suitable for industrial production.

Description

technical field [0001] The invention relates to a fabric surface finishing solution, in particular to an intelligent fabric finishing solution with switchable surface affinity and hydrophobicity and a preparation method thereof, belonging to the fields of polymer synthesis and textile chemical additives. Background technique [0002] The azobenzene polymer mainly introduces the azobenzene structural unit into the polymer chain through chemical bond connection. So far, researchers have synthesized a large number of azobenzene polymers, which are mainly divided into the following four types: terminal azobenzene polymers, side chain azobenzene polymers, and main chain azobenzene polymers. Benzene polymers and doped azobenzene polymers. The azophenyl group has two isomer configurations: the rod-like trans configuration (trans) and the crooked cis configuration (cis), the trans configuration is planar, and the cis configuration is spherical structure. From the perspective of s...
