Abstract

The invention relates to the technical field of printing ink, and particularly relates to a waterborne binder and food-contact waterborne printing ink prepared by using the waterborne binder. The waterborne binder comprises the following raw materials in parts by weight: 15-20 parts of modified rosin, 5-15 parts of starch, 0.5-5 parts of emulsifying monomers, 0.5-5 parts of an initiator, 0.1-2 parts of a pH regulator and 40-60 parts of water, wherein each part of the emulsifying monomers is prepared by the following method: stirring 70-90 parts of acrylic monomers and/or styrene monomers, 0.5-5 parts of an emulsifier and 20-30 parts of water at a temperature of 30-45 DEG C to obtain the emulsifying monomers. According to the waterborne binder, the harm of the use of organic solvents to thehealth of human bodies is avoided, and compared with the existing waterborne acrylic resin, the waterborne binder is more environmentally friendly and is harmless to the human bodies.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to a water-based binder and a food-contact water-based ink prepared by using the same. Background technique [0002] Water-based ink is called ink for short. It is mainly made of water-soluble resin, organic pigment, solvent and related additives through compound grinding. Packaging and printing products. [0003] However, most of the water-based inks used in packaging and printing products currently use water-based acrylic resins as binders, and most of the inks currently used in my country contain petroleum distillates, benzene and its derivatives, or toxic and corrosive ketones, etc. Organic solvents, in the production process, have caused harm to the health of workers. If they are used as food packaging inks and are in direct contact with food, the migration and penetration of small molecular organics will have a negative impact on the health of consumers, especially for Children a...
