Embodiment 1

[0016] Put 600 mL of diethylenetriamine solvent directly into the reaction flask, and after stirring evenly, add 15 g of polyacrylonitrile fiber, and stir evenly at 115°C for 4 h. After the reaction, the fibers were cooled and taken out, and washed with deionized water at 70°C until neutral to obtain a light yellow amino-containing fiber material. Put 10 g of amino-containing fiber material into 300 mL of 10% chlormequat (2-chloroethyltrimethylammonium chloride) solution, then react at 90 °C for 4 h, and the obtained product was washed with deionized water. Dry to constant weight at 50-80°C to obtain off-white fiber material.

Embodiment 2

[0018] Put 750 mL of diethylene solvent directly into the reaction flask, stir evenly, add 15 g of polyacrylonitrile fibers, and stir evenly at 105°C for 4 h. After the reaction, the fibers were cooled and taken out, and washed with deionized water at 70°C until neutral to obtain a light yellow amino-containing fiber material. Put 15 g of amino-containing fiber materials into 600 mL of 10% chlormequat (2-chloroethyltrimethylammonium chloride) solution, then react at 85 °C for 3.5 h, and the obtained product was washed with deionized water, Dry to constant weight at 50-80°C to obtain off-white fiber material.

Embodiment 3

[0020] Put 600 mL of polyethylene polyamine solvent directly into the reaction flask, stir evenly, add 15 g of polyacrylonitrile fibers, and stir evenly at 110°C for 3 h. After the reaction, the fibers were cooled and taken out, and washed with deionized water at 70°C until neutral to obtain a light yellow amino-containing fiber material. Put 15 g of amino-containing fiber materials into 750 mL of 10% chlormequat (2-chloroethyltrimethylammonium chloride) solution, and then react at 85 °C for 3.5 h, and the obtained product was washed with deionized water. Dry to constant weight at 50-80°C to obtain off-white fiber material.

Abstract

The invention relates to a preparation method of a novel polyacrylonitrile fiber material, and belongs to the technical field of polymer materials. The new functional polyacrylonitrile fiber materialhas functional properties such as ion exchange, chelation and bacterial prevention, and can be used as a material for removing organic and inorganic compounds in products, technical processes and waste liquid, a material for gas purification and separation, a cation and anion exchanger, a metal chromatography material, a solid phase purification or extraction material, a biomolecule immobilizationmaterial, a solid phase synthesis material, a chromatography material and the like. The synthetic method has the advantages of being environmentally friendly, convenient to operate, mild in condition, high in macromolecular load activity, good in product form, high in strength, high in grafting amount, renewable and recyclable in material and the like.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a preparation method of a novel polyacrylonitrile fiber material. Background technique [0002] Modified functional fiber materials have many important uses, such as ion exchange, chelation, reaction, catalysis, slow release, antibacterial, deodorant, flame retardant, antistatic, radiation protection, etc. The functional modification of common synthetic fibers or natural fibers can not only maintain the original characteristics and advantages of fibers, but also have various special properties and uses. Research in this field has attracted more and more attention in recent years. Polyacrylonitrile fiber is an important matrix material for synthetic fibers. It is polymerized from acrylonitrile. A large number of cyano groups contained in the structure can undergo chemical reactions such as hydration, hydrolysis, addition, and reduction, and introduce the requ...
