Problems solved by technology

At present, there are mainly acrylate transfer adhesives and styrene-butadiene transfer adhesives on the market. Among them, styrene-butadiene transfer adhesives will produce benzene after UV irradiation, and have poor water resistance. In spring and summer, due to high air humidity, the adhesion is poor. Higher will also be eliminated; acrylic transfer adhesive has poor folding resistance, explosion resistance, and poor embossing resistance

Abstract

The invention relates to an aqueous transfer adhesive which is prepared from the following raw materials in percentage by weight; 50-59.5% of water, 0.2-0.5% of alkyl alcohol ether sodium sulfate, 0.3-0.6% of nonylphenol polyoxyethylene ether ammonium sulfate, 0.3-0.6% of itaconic acid, 0.3-0.6% of acrylamide, 1-1.5% of acrylic acid, 8-13% of ethyl methylacrylate, 15-20% of ethyl methacrylate, 14-19% of butyl acrylate, 0.1-0.3% of sodium persulfate, 0.03-0.06% of sodium hydrogen carbonate, 0.8-1.2% of ammonia water, 0.1-0.3% of a defoamer and 0.1-0.3% of a preservative. The invention further provides a preparation method of the aqueous transfer adhesive. The aqueous transfer adhesive prepared into transfer paper and the subsequent processing are knurling-resistant, solvent-resistant, water-resistant, folding-resistant and explosion-resistant, strong in adhesive force, good in smoothness and leveling property and the like, and satisfy the environmental hygiene requirements.

Description

technical field [0001] The invention relates to an adhesive, in particular to a water-based transfer adhesive and a preparation method thereof. Background technique [0002] In the packaging and printing industry, as people's requirements for packaging are increasing, the requirements for the appearance, anti-counterfeiting and printing effects of various packaging are getting higher and higher. Less, or even no harmful substances are volatilized, and the outer packaging can be recycled and reused, which meets environmental protection requirements. Use the transfer glue to completely transfer the transfer layer of the aluminized coating film (that is, the transfer film) and bond it to cardboard or coated paper to become a colorful anti-counterfeiting paper. After printing, it is widely used in cigarette packs and wine packs. , The packaging of daily necessities, to achieve anti-counterfeiting, beautiful and other functions. [0003] Existing transfer adhesives include wate...
