Abstract

The invention discloses water-soluble cigarette packet laser transferring glue and a preparation method of the water-soluble cigarette packet laser transferring glue. The water-soluble cigarette packet laser transferring glue comprises a water-soluble crylic acid emulsion polymer with a solid content of 45-55wt%. The polymer is formed by copolymerization of a crylic acid C2-C4 alkyl ester monomer and a mixture of a methacrylic acid C1-C4 alkyl ester monomer and a crylic acid monomer under effects of deionized water, an emulsifying agent, an initiator, a chain transfer agent, a pH conditioning agent and a water-soluble additive. The glue is strong in gluing force, enables a laser aluminum coated layer on a plastic film base material to completely transfer towards a paper face, is free of dropping, good in bending resistance, does not contain organic solvents, is low in residual monomer quantity, does not contain a phthalic acid ester type plasticizer or formaldehyde.

Description

Technical field [0001] The invention relates to an adhesive manufacturing technology, in particular to a water-based cigarette packet laser transfer glue and a preparation method thereof. Background technique [0002] At present, transfer laser cardboard as a new type of environmentally friendly packaging material has been widely used in the field of cigarette packages. The transfer of laser cardboard is to use the peelability of the laser aluminized layer to transfer the laser aluminized layer with various laser effects vapor-deposited on the plastic film to the paper through an adhesive to form paper with various aesthetic effects. The process includes: (1) coating release and information coatings on the PET film (2) molding on the coating to form an anti-counterfeiting laser layer (3) vacuum aluminum plating on the laser layer (4) laser plating with adhesive The aluminum film and the cardboard are compounded (5) the PET base film is peeled to form a laser cardboard with a las...
