Embodiment 1

[0085] (1) p -Nafluorobutylaniline

[0086] 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-neck flask equipped with a magnetic stirrer, a thermometer and a condenser tube, stir and heat to 60 °C. 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, 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 sulfate for 8 h, filt...

Abstract

The invention discloses an intelligent surface hydrophilicity and hydrophobicity transferable textile finishing solution, which has an effective ingredient of perfluoroalkyl azobenzene acrylate copolymer. The perfluoroalkyl azobenzene acrylate copolymer emulsion is prepared by esterifying perfluoroalkyl benzeneazophenol serving as an initial raw material with acryloyl chloride to obtain an acrylate monomer containing perfluoroalkyl azobenzene, and polymerizing with hydroxyethyl methylacrylate and butyl acrylate through emulsion. When the emulsion is polymerized, the copolymer has low polymerization, short molecular main chain and small molecular chain winding degree by increasing the dosage of initiator, so that the side group azobenzene has strong molecular heterogeneous performance, andis favorable to surface hydrophilicity and hydrophobicity transformation. The intelligent water-repelling finishing agent is mild in preparing reaction condition and simple in preparation process, andis suitable for industrial production.

Description

[0001] The present invention belongs to a divisional application of an intelligent surface affinity switchable fabric finishing solution and a preparation method thereof, the application date is April 18, 2017, and the application number 2017102548616 is a patent application, and belongs to the product technology part. technical field [0002] 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 [0003] 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...
