Problems solved by technology

However, judging from the existing actual use conditions, water-based inks instead of solvent inks mainly face two major problems: slow drying speed and poor adhesion to printing substrates; since the main solvent of water-based inks is water, the volatilization speed of water is relatively low. Solvents in solvent inks such as toluene, acetone, ethyl acetate, ethanol, methanol

Abstract

The invention discloses acrylate emulsion of water-based ink for soft PVC (Polyvinyl Chloride) and a preparation method thereof. The acrylate emulsion is prepared from the following raw materials in parts by weight: 4.0 to 4.8 parts of an emulsifier A, 40.0 to 60.0 parts of a mixture A, 2.0 to 6.0 parts of an emulsifier B, 25.5 to 33.0 parts of a mixture B, 25.5 to 31.5 parts of a mixture C, 0.66 to 1.34 parts of an initiator, 4.8 to 18.0 parts of alkali salt and 150.0 to 230.0 parts of water. The acrylate emulsion of the water-based ink is specifically synthesized aiming at application to the soft PVC, and the preparation method of the acrylate emulsion adopts a novel a core-shell emulsion polymerization technology and an interpenetrating polymer network emulsion polymerization technology; an acrylate chain segment with stronger hydrophily is used as a core layer of the acrylate emulsion, and better re-dissolution property and better compatible stability with water-based ink color paste are realized; since the interpenetrating polymer network emulsion polymerization technology is adopted, the strength of an emulsion coating film is greatly increased, the adhesive force of the water-based ink on a soft PVC base material is increased, and the water resistance is good.

Description

technical field [0001] The invention relates to the technical field of emulsion synthesis, in particular to an acrylate emulsion of soft PVC water-based ink and a preparation method thereof. Background technique [0002] Water-based ink is a very important ink in printing ink, and its consumption accounts for 8% to 12% of the total printing ink. Compared with solvent ink, offset printing ink and screen printing ink, the production process of water-based ink is relatively simple, and there is basically no organic solvent emission in the production process and printing process. It is a relatively green and environmentally friendly ink. However, judging from the existing actual use conditions, water-based inks instead of solvent inks mainly face two major problems: slow drying speed and poor adhesion to printing substrates; since the main solvent of water-based inks is water, the volatilization speed of water is relatively low. Solvents in solvent inks such as toluene, acetone...
