摘　　要：三苯乙烯基苯酚聚氧乙烯醚(TSPOE-n)经五氧化二磷酯化,水解后得到三苯乙烯基苯酚聚氧乙烯醚磷酸酯盐(TSPOEP-n,n=13,16,20,29),以其作为分散剂用于分散染料的液体化。利用红外光谱法表征了分散剂的化学结构;通过粒径分析仪考察了TSPOEP-n中环氧乙烷(EO)数对液体分散染料贮存稳定性的影响,并对比了液体与粉体分散染料染色性能的差异。结果表明:经TSPOEP-n稳定的液体分散染料的粒径均小于215 nm,具有较好的贮存稳定性和高温(130℃)分散稳定性,且上染率高于粉体分散染料,染色残液化学需氧量(COD)远低于粉体分散染料得到的对比样。Liquid disperse dyes have become a research hotspot in recent years because they are able to meet the requirements of automation of printing and dyeing,batching systems,as well as energy saving in production.However,the liquid disperses dyes with a low dosage of dispersant are easy to be coarse and even coagulated and precipitated.In the process of immersion dyeing,the dispersion stability at high temperatures is poor,and the dye precipitates out,which leads to a problem of uneven dyeing and poor reproducibility.So,the dispersant is the key to preparing high-performance liquid to disperse dyes.The tristyrenylphenol polyoxyethylene ether(TSPOE-n)was esterified with phosphorus pentoxide,and hydrolyzed to obtain the tristyrenylphenol polyoxyethylene ether phosphate(TSPOEP-n;n=13,16,20 and 29),which was used as a dispersant for the liquidation of disperse dyes.The chemical structure of the dispersant was characterized by the infrared spectrum.The effect of ethylene oxide(EO)number in TSPOEP-n on the storage stability of liquid dispersed dyes was investigated by particle size analyzer,and the dyeing properties of liquid and powder disperse dyes were compared.The liquid disperse dyes prepared by dispersant TSPOEP-n(n=13,16,20 and 29)with EO numbers were all nanoscale and the average particle size was 175~215 nm.The PDI was about 0.2,and the absolute value of Zeta potential was greater than 25 mV.After 100 days of storage,when the EO number was 13,16,20,and 29,the dispersed dye particle size increased by 35.3,20.2,34.4,and 58.8 nm,respectively.Disperse dyes'particle size and distribution tended to be stable.And the average particle size was less than 350 nm,which could meet the dyeing requirements.After the dispersed dyes were heat treated at a high temperature(130℃)and filtered by double-layer filter paper,there were a small number of dye particles on the filter paper and the dye filtration time(stage)residue rating(stage)reached C 3 or above.When the dye mass fraction was 1%~5%,the unevenness of the fabric dyed by l
