Abstract

The invention discloses an acrylic emulsion for PVC (Polyvinyl Chloride) water-based ink, and belongs to the technical field of emulsions. The acrylic emulsion is of a core-shell structure and comprises the following components in percentage by mass: 2-10% of an anionic emulsifier, 0-0.5% of a reaction type emulsifier, 0-3% of a non-ionic emulsifier, 0.05-2% of ammonium persulfate, 0.5-1.0% of 30% ammonium hydroxide, 0.1-0.3% of a bactericide, 40-70% of deionized water, a core structure monomer and a shell structure monomer, wherein the core structure monomer comprises the following components in percentage by weight: 0.1-10% of methyl methacrylate, 0-5% of ethyl acrylate, 0-5% of acrylamide and 0-5% of a silane coupling agent; the shell structure monomer comprises the following components in percentage by weight: 10-25% of methyl methacrylate, 15-25% of butyl acrylate, 0-10% of ethyl acrylate, 0-1% of methacrylic acid, 0-1% of crylic acid and 0-5% of caprolactam. The acrylic emulsion is excellent in adhesion property and good in water resistance on a PVC substrate.

Description

technical field [0001] The invention belongs to the technical field of emulsions, relates to an acrylic emulsion, in particular to an acrylic emulsion used for PVC water-based ink and a preparation method thereof. The acrylic emulsion of the present invention has excellent adhesion and good water resistance on the PVC substrate, and at the same time, no alcohol substances harmful to human body are used in the synthesis process, which is more in line with people's requirements for paying attention to health. Background technique [0002] PVC is one of the most versatile general-purpose plastics. PVC has good water-repellent properties, and can be used for packaging of food, seasonings, beverages, etc., flexible packaging for packaging various items, beer bottle caps and beverage bottle cap linings, and wallpaper. Traditional PVC printing mostly uses solvent-based inks for the sake of printing effect and adhesion. The volatilization of the solvent will cause health damage to ...
