Problems solved by technology

[0007] In order to solve the above problems, the present invention provides a water-based plastic ink emulsion for surface printing and a preparation method thereof, which effectively avoids the very high production process requirements and relatively complicated production process for resin emulsions in the prior art. The core-shell structure polybutyl acrylate random copolymer emulsion prepared by the emulsion polymerization process makes the adhesion very weak after forming a film on the plastic surface

preparation example Construction

[0038] The preparation method of the water-based plastic ink emulsion facing surface printing comprises the radical emulsion polymerization method under the reversible addition-fragmentation chain transfer, and the radical emulsion polymerization method under the reversible addition-fragmentation chain transfer comprises the following steps:

[0039]Step 1: Dissolve 0.425-0.45 parts by weight of emulsifier in 85-90 parts by weight of deionized water in container one, and then add 15-45 parts by weight of acrylic acid to container one Ester, 15-25 parts by weight of styrene, 20-70 parts by weight of methacrylate and 1.9-2.23 parts by weight of chain transfer agent are uniformly mixed to obtain a pre-emulsion one;

[0040] Step 2: Dissolve 0.05-0.075 parts by weight of emulsifier in 10-15 parts by weight of deionized water in container two, and then add 10-15 parts by weight of acrylic acid to container two Isobornyl or isobornyl methacrylate and mixed uniformly to obtain pre-em...

Abstract

A water-based plastic ink emulsion for surface printing and a preparation method thereof, comprising emulsion particles, the polymer in the emulsion particles is a diblock copolymer, and the synthesis method of the diblock copolymer is reversible addition ‑The free radical emulsion polymerization method under the fragmentation chain transfer; the polymer in the emulsion micelle is shown in structural formula (I): in combination with its preparation method, such technical effects can be achieved: 1) after the emulsion is formed into a film, it can be used in various plastics Good adhesion on the substrate and good flexibility; 2) The synthesis process is simple and does not produce three wastes; 3) After mixing with the color paste, the system is stable without delamination, flocculation, and precipitation.

Description

technical field [0001] The invention relates to the technical field of water-based plastic ink emulsions, in particular to a water-based plastic ink emulsion for surface printing and a preparation method thereof. Background technique [0002] Printing is a technology that transfers the ink to the surface of paper, fabric, plastic, leather and other materials through plate making, ink application, and pressurization to copy the contents of the original manuscript in batches. Printing is the process of transferring the approved printing plate to the substrate through printing machinery and special ink. The corresponding printing industry is one of the industries with the fastest technological progress in the world in the past 20 years, and has now entered the era of digital printing. Moreover, due to the rapid growth of high-end color printed matter, and the wide application of high-tech such as computers and electronics in the printing process, the printing industry's enviro...
