Embodiment 1

[0042] Example 1 Preparation method and application of anti-marine biofouling chelation ion exchange polyester-cotton blended yarn

[0043] Step 1. Preparation of epoxy functional polyester-cotton blended yarn

[0044] Immerse 100 grams of commercially available 18 counts of 65 / 35 polyester-cotton natural color blended yarn into a polyester resin made of glycidyl methacrylate / methyl methacrylate / ethylene glycol dimethacrylate in a ratio of 75:10:15. Acrylate functional resin solution, padding three times at room temperature for 30 minutes, pulling out the yarn, drying, and gaining 95 grams in weight to obtain epoxy functional polyester-cotton blended yarn, which contains rings through chemical analysis. Oxygen 2.192mmol / g (the epoxy functional polyester-cotton blended yarn epoxy measured value is lower than the theoretical value, indicating that the preparation process of the polyacrylate functional resin solution and the hiding of the resin coating on the fiber surface will c...

Embodiment 2

[0052] Example 2 Preparation of anti-marine biofouling chelated ion-exchange polyester

[0053] According to the method and operation steps of Example 1, the commercially available 18-count 65 / 35 natural color polyester-cotton blended yarn in step 1 of Example 1 was replaced with commercially available 18S natural color polyester single yarn, and the anti-marine biofouling Chelated ion-exchange polyester, through adsorption experiments and chemical analysis, calculates that the retention adsorption capacity of anti-marine biofouling chelated ion-exchange polyester to copper chloride is 130.2mg / g.

Embodiment 3

[0054] Example 3 Preparation of anti-marine biofouling chelation ion exchange 32S / 2 acrylic fiber / cotton bulked yarn

[0055] According to the method and operation steps of Example 1, the commercially available 18 counts of 65 / 35 natural color polyester-cotton blended yarn in Step 1 of Example 1 was replaced with commercially available 32S / 2 acrylic fiber / cotton bulked yarn, and the anti-marine Biofouling chelated ion-exchanged acrylic / cotton bulked yarn, through adsorption experiments and chemical analysis, calculated the retention adsorption capacity of anti-marine biofouling chelated ion-exchanged acrylic / cotton bulked yarn to copper chloride was 483.3mg / g.

Abstract

The invention provides a chelation ion exchange fiber capable of resisting marine organism stain and a preparation method thereof. Synthetic fibre or synthetic fibre and cotton and hemp blend fiber serve as base material fibres dipped with the polyacrylic ester function resin solution containing an epoxy group to prepare the epoxy function fibre; and then, the epoxy function fibre successively carries out ring-opening reaction with the organic polyamine, carries out Micheal addition reaction with acrylonitrile, carries out quaternization reaction with 5-chloromethyl methyl salicylic aldehyde and carries out hydroxylamine addition reaction. A quaternary ammonium group, salicylaldoxime and an amidoxime function group are successively increased and led in the base material fibre surface to obtain the Chelation ion exchange fiber capable of resisting marine organism stain.

Description

technical field [0001] The invention relates to a chelating ion exchange fiber, in particular to a chelating ion exchange fiber coated with amidoxime, salicylaldoxime and quaternary ammonium-based functional resin on the surface of the substrate fiber, which has the characteristics of anti-fouling of marine organisms and can be used The separation and enrichment of uranium in seawater belongs to the field of functional materials. technical background [0002] Extracting uranium from seawater is one of the ways of energy development. Although the concentration of uranium in seawater is very low, only about 3.3 μg / L, the total reserves are estimated to be as high as 4 billion tons. Since the 1960s, many countries have conducted extensive research on the extraction of uranium from seawater. But only Japan's brush-like chelating fiber adsorption method has practical value for extracting uranium from seawater. However, if any solid matter is permanently stored in seawater, seri...
