Embodiment 1

[0031] 95 parts of molecular weight are 10000 polyester diols and 5.0 parts of hexamethylene diisocyanate and 0.05 parts of organic bismuth and 2.5 parts of hydroxybutyl acrylate in a four-necked flask equipped with a stirrer and a thermometer. 90°C for 6 hours to prepare a prepolymer. A mixed solution consisting of 1 part of dimethylolpropionic acid, 0.05 part of vegetable oil polyol with a hydroxyl value of 163 mgKOH / g, 50 parts of nitrogen methyl pyrrolidone and 100 parts of butyl acrylate was added, and the reaction was maintained at 75° C. for 4 hours. Next, cool down to below 60°C, add 200 parts of acetone to dilute, then add 0.8 parts of triethylamine to neutralize, cool down to below 30°C, add 300 parts of deionized water pre-cooled to 5°C under high-speed stirring, and finally 0.32 parts of methylenediamine and 0.21 parts of dimethylamine were added and reacted at 25°C to 30°C for 30 minutes. Raise the temperature to 70°C to keep warm and vacuumize to remove solvents...

Embodiment 2

[0033] Put 88 parts of polyether diols with a molecular weight of 10000, 8 parts of toluene diisocyanate, 0.05 parts of organic bismuth and 2.5 parts of hydroxybutyl acrylate in a four-necked flask equipped with a stirrer and a thermometer, and keep it warm at 90°C under a nitrogen stream. 6 hours to make a prepolymer. Then add 1.5 parts of dimethylolpropionic acid, 1 part of trimethylolpropane, 0.05 part of vegetable oil polyol with a hydroxyl value of 163 mgKOH / g, 50 parts of nitrogen methyl pyrrolidone and 100 parts of butyl acrylate to form a mixed solution, The reaction was incubated at 75°C for 4 hours. Next, cool down to below 60°C, add 200 parts of acetone to dilute, then add 1.2 parts of triethylamine to neutralize, then cool down to below 30°C, add 300 parts of deionized water pre-cooled to 5°C under high-speed stirring, and finally 0.48 parts of ethylenediamine and 0.18 parts of di-n-octylamine were added, and it was made to react at 25-30 degreeC for 30 minutes. ...

Embodiment 3

[0035] 90 parts of polyester diols and 6 parts of hexamethylene diisocyanate and 0.05 parts of organic bismuth and 2.5 parts of hydroxybutyl acrylate are charged in a four-necked flask equipped with a stirrer and a thermometer, and the molecular weight is 10000. 90°C for 6 hours to prepare a prepolymer. Then add a mixed solution consisting of 1.5 parts of dimethylolpropionic acid, 0.1 part of vegetable oil polyol with a hydroxyl value of 163 mgKOH / g, 50 parts of nitrogen methyl pyrrolidone and 100 parts of butyl acrylate, and react at 75° C. for 4 hours. Next, cool down to below 60°C, add 200 parts of acetone to dilute, then add 1.2 parts of triethylamine to neutralize, then cool down to below 30°C, add 300 parts of deionized water pre-cooled to 5°C under high-speed stirring, and finally 0.41 parts of ethylenediamine and 0.19 parts of di-n-butylamine were added and reacted at 25°C to 30°C for 30 minutes. Raise the temperature to 70°C to keep warm and vacuumize to remove solve...

Abstract

The invention discloses novel modified resin used as digital ink. The novel modified resin comprises the following components in parts by weight: 10 to 30 parts of polyester polyol, 4 to 12 parts of diisocyanate, 0.5 to 5 parts of hydroxymethyl propionate, 0.05 to 0.1 part of catalyst, 10 to 20 parts of methacrylate monomer, 4 to 15 parts of low-molecular polyalcohol, 1 to 4 parts of hydroxylated acrylic, 0.5 to 2 parts of neutralizing agent, 30 to 70 parts of deionized water, 0.5 to 5 parts of diamine and 0.5 to 1.5 parts of initiator. The invention also discloses a preparation method of the novel modified resin. The digital-like ink produced by utilizing the novel modified resin is high in over-net mesh number which can reach 4000-mesh gauze, high in screentone clarity and bright in color, and the printed pattern effect can be comparable with the digital printed product.

Description

technical field [0001] The invention belongs to the field of molecular materials science, and specifically relates to a novel modified resin used for making digital ink and a preparation method thereof. Background technique [0002] The mesh number of the traditional dot pulp passing is low, and it can only pass 1200-1500 mesh yarn, which leads to poor clarity of the printed pattern. At the same time, the operation of the traditional dot sizing elliptical machine is easy to block the mesh, and there is no way to continuously operate efficiently. Although the new digital printing technology has high pattern definition. Bright colors and other characteristics, but the production efficiency is low, the production cost is high, and the investment in equipment is large, so it is not suitable for large-scale promotion in the industry. At the same time, the digitally printed pattern feels hard, which is not favored by consumers. [0003] The research and development of imitation ...
