Problems solved by technology

[0002] Anthraquinone compounds have the ability to transfer electrons, so the application of anaerobic microorganisms in the degradation of azo dyes and nitrates can increase the degradation rate by more than 1 order of magnitude, and grafting them on the carrier can effectively avoid the "secondary pollution" of the water body ", the publicly reported carrier has polymer film (publication number CN103936146B), filler (publication number CN110157007A) etc., but polymer film grafting efficiency is limited, problems such as filler recovery use inconvenient still exist, therefore need to improve degradation rate and recovery Feasibility of reuse

[0024] The general formula of fluorosilicone polymer A containing amino group and mercapto group is SiMe 3 O(SiOMeR f ) 11.7 (SiOMe 2 ) 22.5 (SiOMeR N ) 3.5 (SiOMeR s ) 4.1 SiMe 3 , Me, R f , R s As mentioned above, R N is 3-aminopropyl;

[0025] The general formula of amino and mercapto fluorosilicone polymer B is SiMe 3 O(SiOMeR f ) 18.5 (SiOMe 2 ) 29.4 (SiOMeR N ) 7.8 (SiOMeR s ) 6.2 SiMe 3 , Me, R f , R s As mentioned above, R N Is N-2-aminoethyl-3-aminopropyl;

[0026] The general formula of amino and mercapto fluorosilicone polymer C is HOSiMe 2 O(SiOMeR f ) 7.7 (SiOMe 2 ) 11.6 (SiOMeR N ) 3.9 (SiOMeR s ) 4.2 SiMe 2 OH, Me, R f , R s As mentioned above, R N is 3-diethylenetriaminopropyl;

Embodiment 1

[0028] 9,10-anthraquinone-2-sulfonyl chloride, triethylamine, amino-containing and mercapto-containing fluorosilicon polymer A are compounded according to the molar ratio of 1:1.15:0.4.

[0029] At 0-5°C, add amino group and mercapto-containing fluorosilicone polymer A to 10 times the weight of tetrahydrofuran, add triethylamine, stir evenly, dropwise add 200 mg / ml 9,10-anthraquinone- The THF solution of 2-sulfonyl chloride was stirred and reacted for 6 hours, placed at 30°C and continued to stir for 5 hours, filtered, and the filtrate was removed from THF and unreacted triethylamine to obtain an anthraquinone-containing fluorosilicone polymer, denoted as P- 1.

Embodiment 2

[0031] 9,10-anthraquinone-2-sulfonyl chloride, potassium carbonate, fluorosilicone polymer B containing amino group and mercapto group are prepared according to the molar ratio of 1:1.3:0.15.

[0032] At 0-5°C, add amino group and mercapto-containing fluorosilicone polymer B to 10 times the weight of 1,4-hexadioxide, add potassium carbonate, stir evenly, and dropwise add 9 , 1,4-hexadioxide solution of 10-anthraquinone-2-sulfonyl chloride, stirred and reacted for 8 hours, placed at 30°C and continued to stir for 5 hours, filtered, and 1,4-hexadioxide was removed from the filtrate, An anthraquinone-containing fluorosilicone polymer was obtained, denoted as P-2.

Abstract

The invention belongs to the technical field of waste water treatment and specifically relates to a fiber, a preparation method, a textile fabric and an application thereof. The textile fabric is obtained by enabling 9, 10-anthraquinone-2-sulfonyl chloride to react with amino and sulfydryl contained fluorosilicone polymer to obtain anthraquinone contained fluorosilicone compound and processing silicon rubber and the anthraquinone contained fluorosilicone compound according to a weight ratio of 100:0.05-2. As the anthraquinone contained fluorosilicone polymer is enriched and cured on the surface of the fabric, the fabric has better biodegradation promotion effect on azo dyes and nitrate.
