Abstract

The invention relates to an aqueous transfer glue which is prepared through an emulsion polymerization with methyl methacrylate, butyl acrylate monomer, acrylic acid 2- Octyl Nitrite, a functional monomer, an initiator, an emulsifier buffering agent, a functional auxiliary agent, a PH adjusting agent and deionized water. The invention also provides the preparation method of the aqueous transfer glue. The invention is characterized by simple technology, low cost, environment friendliness and the ultimate product meets the 16 limitation requirements on harmful substances in the tobacco industry. Meanwhile, the golden paperboard and silver paperboard prepared from the aqueous transfer glue provided in the invention have better flexibility resistance and brightness than those of the products currently for sale. In particular, regarding to help with the limitation of harmful substances, the aqueous transfer glue is far better than the carboxylated styrene-butadiene rubber latex used in the current tobacco package industry.

Description

technical field [0001] The invention relates to an adhesive and a preparation method thereof, in particular to a water-based transfer adhesive used for preparing various gold cardboards and silver cardboards by a transfer method and for compounding laser films and various papers and a preparation method thereof. Background technique [0002] Transfer glue is an important adhesive for preparing gold cardboard, silver cardboard, laser film and various paper composites. Although the transfer adhesive has long been water-based, but at present, carboxylated styrene-butadiene emulsion is mostly used. The most representative product is the product of the German BASF company. The carboxylated styrene-butadiene transfer adhesive produced by BASF has always dominated the Chinese cigarette pack industry. The performance is very excellent, but with the increase in the limit requirements of harmful substances in the tobacco industry, and the extremely stringent requirements for the adhes...
