Abstract

The invention discloses a novel aluminum-free lining paper coating for cigarette package and a preparation method thereof. The method includes preparation of core-shell structure cross-linking type polyacrylate emulsion and preparation of a novel cigarette aluminum-free lining paper coating. The method includes: adding deionized water, an emulsifying agent and a core layer monomer in a reaction kettle, stirring and emulsifying, heating to 75-80 DEG C, adding water solution of an initiating agent dropwise, leading polymerization reaction, and manufacturing core layer particles; simultaneously adding a core layer olefin monomer and the water solution of the initiating agent which are mixed well in a core layer particle reaction system dropwise, and adding tert-butyl hydroperoxide water solution after reaction; cooling, filtering, and discharging to obtain the core-shell structure cross-linking type polyacrylate emulsion. The obtained novel cigarette aluminum-free lining paper coating is suitable for being coated on aluminum-free paper, the paper can replace aluminum foil composite paper to be applied to the cigarette package after being dried, and the novel aluminum-free lining paper coating has the advantages of being high in strength, good in tightness and water resistance and the like.

Description

technical field [0001] The invention relates to an inner-lining paper coating, in particular to a novel aluminum-free inner-lining paper coating for cigarette packaging and a preparation method thereof, belonging to the field of water-based polymers. Background technique [0002] Packaging materials in the food and tobacco industries at home and abroad have high requirements for freshness preservation and anti-corrosion. At present, most of them use aluminum foil and paper composites, which are expensive, and the paper cannot be recycled, resulting in a large waste of resources; solvent-based Coatings can meet the coating requirements of aluminum-free paper, but solvent-based coatings contain organic solvent residues that cannot meet the hygienic requirements of packaging materials in the food and tobacco industries; water-based coatings can avoid the above defects and become a research hotspot. Existing water-based paints are formulated from polymer emulsions and various ad...
