Embodiment 2

[0028] Weigh 10.5g of diethanolamine and 30g of ethanol into the four-necked flask, slowly raise the temperature to 35°C, then slowly drop 8.6g of methyl acrylate into the four-necked flask, react for about 6 hours, and remove the ethanol under reduced pressure to obtain AB 2 type monomer.

[0029] Add 19.1gAB in the four-necked bottle 2 Type monomer, 0.44g glycerol, 0.20g p-toluenesulfonic acid, react at 100°C for 4h, and then continue to react for 4h under vacuum. The temperature of the reactant was lowered to 80°C, 2.28g of succinic anhydride was added, reacted for 4h, then cooled to below 40°C, and neutralized to pH 8-9 with 30% sodium hydroxide solution.

[0030] Dissolve 4.84g of Reactive Brilliant Orange K-GN in 29g of water, add the above product, and react at 95°C for 2h to obtain an orange water-soluble polymer dye based on hyperbranched polyamine-ester.

Embodiment 3

[0032] Weigh 10.5g of diethanolamine and 30g of ethanol into a four-necked flask, slowly raise the temperature to 40°C, then slowly drop 10g of ethyl acrylate into the four-necked flask, react for about 24 hours, and remove ethanol under reduced pressure to obtain AB 2 type monomer.

[0033] Add 20.5gAB to the four-necked bottle 2 Type monomer, 0.71g triethanolamine, 0.21g p-toluenesulfonic acid were reacted under vacuum at 140°C for 8h to obtain the third generation hyperbranched polyamine-ester. The temperature of the reactant was lowered to 80°C, 5.7g of succinic anhydride was added, reacted for 4h, then cooled to below 40°C, and neutralized to pH 8-9 with 30% sodium hydroxide solution.

Abstract

The invention relates to the technical field of special polymeric dyes for leather, fur and leather and fur products, in particular to a preparation method for a polymeric dye based on hyperbranched polyamine-ester. The preparation method comprises the following steps: by taking alcohol amine and acrylate as raw materials, reacting the alcohol amine and the acrylate, and removing a solvent after the reaction is ended to obtain an AB2 type monomer; reacting the AB2 type monomer, a catalyst and a micromolecular polyhydroxy compound to obtain hydroxyl-terminated hyperbranched polyamine-ester, and performing modification by using acid anhydride; reacting acid anhydride modified hyperbranched polyamine-ester with an active dye to obtain the polymeric dye. Compared with the prior art, the obtained polymeric dye can effectively improve the dyeing fastness, washing resistance, sweat resistance and other performance of the leather, the fur and the leather and fur products, the dye utilization rate is increased, and the content of dyes in waste liquor is reduced.

Description

(1) Technical field [0001] The invention relates to the technical field of polymer dyes for leather, fur and their products, in particular to a preparation method of polymer dyes based on hyperbranched polyamine-ester. (2) Background technology [0002] Dyeing is an important process in the leather production process, which plays an important role in imparting bright colors and beautiful appearance to the finished leather. In recent years, with the improvement of environmental protection requirements and the progress of society, people have put forward higher standards for leather dyes, which not only require dyes to be lightfast, washable, friction-resistant, and firmly bonded, but also require dyes to have higher absorption rates. Wastewater is easier to treat. However, at present, acid dyes and direct dyes in the laying industry are mainly used for dyeing in tanning production. These dyes can only be combined with skin collagen fibers in the form of ionic bonds, hydr...
