Problems solved by technology

However, the emulsifiers used in the synthesis process of traditional resin emulsion binders are mostly small molecule emulsifiers. After adding alcohol solvents (mainly alcohol), the emulsifiers are easily dissolved, which makes the latex particles demulsify and cannot be used.

Embodiment 1

[0054] (1) Preparation of alcohol-resistant water-based acrylate emulsion resin

[0055] SMA with a molecular weight of 1000g / mol and octaalkylamine are put into the reaction bottle according to the mass ratio of 1:1.1 (the primary amine is slightly excessive to ensure complete ring opening, the same below), ethyl acetate (EA, the same below) is used as the solvent, 60°C Under the condition of reaction 2h. After cooling to room temperature, octaalkylsulfonic acid in the amount of octaalkylamine and the like was added to the reaction solution, and reacted at room temperature for 4 hours. The reaction solution was distilled off under reduced pressure to remove the EA solvent, and then dissolved in 100mL of ethanol to prepare a 1mol / L KOH ethanol solution, which was added dropwise to the ethanol solution until the pH value of the system was greater than or equal to 7. Emulsifier A is obtained.

[0061] SMA with a molecular weight of 2000g / mol and dodecylamine were put into the reaction flask at a mass ratio of 1:1.1, EA was used as a solvent, and reacted at 80°C for 2h. After cooling to room temperature, the reaction liquid was added with dodecylamine and other substances such as propane sultone, and reacted at room temperature for 4 hours. The reaction solution was distilled off under reduced pressure to remove the EA solvent, and then dissolved in 100mL of ethanol to prepare a 1mol / L NaOH ethanol solution, which was added dropwise to the ethanol solution until the pH value of the system was greater than or equal to 7. Emulsifier A is obtained.

[0067] SMA with a molecular weight of 3000g / mol and dodecylamine were put into the reaction flask at a mass ratio of 1:1.1, and EA was used as a solvent, and reacted at 100°C for 2h. After cooling to room temperature, dodecylbenzenesulfonic acid and dodecylamine were added to the reaction solution, and reacted at room temperature for 4 hours. The reaction solution was distilled off under reduced pressure to remove the EA solvent, and then dissolved in 100mL of ethanol to prepare a 1mol / L NaOH ethanol solution, which was added dropwise to the ethanol solution until the pH value of the system was greater than or equal to 7. Emulsifier A is obtained.

Abstract

The invention provides an alcohol-resistant water-based resin emulsion binder for quick-drying ink and a preparation method thereof. The alcohol-resistant water-based resin emulsion binder adopts an emulsifier A and a reactive nonionic surfactant as an emulsification system, and synthesizes IBOMA as a main monomer to ensure the stability of the emulsion after adding alcohol and prevent demulsification . The emulsifier A can effectively reduce the possibility of being dissolved by alcohol, and at the same time, it can play the role of protective colloid, provide strong electrostatic repulsion for latex particles, and play the role of coating protection. The alcohol-resistant water-based acrylate emulsion resin is mixed with ethanol as ink binder, which can greatly increase the ink drying rate, and can be well dispersed without adding other resins during grinding, and can directly form a stable paint film with uniform dispersion and high shading rate , and the color paste has good stability, reduces VOC content and the amount of solvent raw materials, is more environmentally friendly and economical, and has a good industrialization prospect.

Description

technical field [0001] The invention belongs to the technical field of water-based inks, in particular to an alcohol-resistant water-based resin emulsion binder for quick-drying inks and a preparation method thereof. Background technique [0002] Water-based ink uses water as a solvent. Due to its extremely low VOC content and excellent environmental protection performance, it can effectively solve the current emission and pollution problems in the packaging and printing industry, and will replace traditional solvent-based inks. The binders of water-based inks are generally water-based resins. At present, the research on binders at home and abroad mainly includes modified pine water-soluble resins, polyacrylic acid water-soluble resins and emulsion-type water-soluble resins. Among them, emulsion-type binders are a kind of development. Very fast type. Compared with the paint attached to the porous substrate, the substrate to which the ink is attached is generally a dense mat...
