High polymer material formulation of three-dimensional gold stamping electrified aluminium hot stamping foil coating and preparation method thereof

Abstract

The invention relates to a high polymer material formulation of three-dimensional gold stamping electrified aluminium hot stamping foil coating and a preparation method thereof. The high polymer material formulation comprises the components based on the parts by weight: 10-20 parts of modified polyurethane, 1-5 parts of polyformaldehyde, 5-10 parts of poly ethyl acrylate, 5-10 parts of poly alkylene oxide resin, 5-15 parts of cellulosic resin, 8-20 parts of acrylic resin, 30-60 parts of butanone, 5-10 parts of acetic ether, 5-10 parts of n-propyl acetate and 1-20 parts of polyvinyl butyral. The preparation method comprises: 1) according to the requirement of the formulation, firstly putting all solvents into a reaction kettle, heating to 20-45 DEG C and then stirring; 2) keeping stirring, sequentially putting the modified polyurethane, the polyformaldehyde, the poly ethyl acrylate, the poly alkylene oxide resin, the cellulosic resin, the acrylic resin and the polyvinyl butyral into the reaction kettle according to the proportion, and stirring for 0.5-2.0h; 3) after all solid is dissolved and evenly mixed together, stopping the blend and curing for 3-5h; 4) measuring the content of the solid and adjusting to theoretical value; and 5) slowly stirring and cooling to 20 DEG C. The invention has the characteristics of simple preparation technique, clear three-dimensional hot stamping, good effect of stamping, good ductility of a formed film of the product and the like.

Description

Technical field [0001] The invention relates to a special polymer material, in particular to a formulation and preparation method of an anti-counterfeiting polymer material. Background technique [0002] The anti-counterfeiting technology of the packaging industry is changing with each passing day. The three-dimensional hot stamping technology is a new type of packaging anti-counterfeiting technology. It is a composite technology combining hot stamping technology and embossing technology. The three-dimensional hot stamping technology can form a relief-like three-dimensional pattern on the surface of the product. , Can make the product better anti-counterfeiting and more beautiful. However, the existing three-dimensional hot stamping anodized aluminum hot stamping foil coating has negative effects on the anti-counterfeiting of the product and the aesthetics of the product. The main reason is that the formula is unreasonable and the preparation process is not mature enough. The pro...
