Printable hot stamping layer and preparation method thereof

Abstract

The invention relates to a printable hot stamping layer and a preparation method thereof, and the printable hot stamping layer adopts the following components and is prepared according to the following parts by weight: 15-25 parts of modified polyurethane resin, 3-10 parts of furfural polyketone resin, 10-20 parts of thermoplastic acrylic resin, 1-12 parts of cellulose nitrate, 2-5 parts of cellulose resin, 0-10 parts of polyvinyl butyral, 30-60 parts of butanone, 5-10 parts of ethyl acetate, 5-10 parts of n-propyl ester, 1-2 parts of reaction initiator and 0.5-1 part of reaction terminator. The method comprises the following steps: 1) firstly pouring all solvents into a reaction kettle according to the requirements of the formula, heating to 50-80 DEG C and stirring; 2) keeping stirring, sequentially pouring polyurethane resin, furfural polyketone resin, modified acrylic resin, cellulose nitrate, cellulose resin and polyvinyl butyral into the reaction kettle, dripping the reaction initiator into the reaction kettle within 1 hour, and continuously stirring for 2.0-3.0 hours; 3) detecting the infrared spectrum and adding the reaction terminator; 4) measuring the solid content, and adjusting to the theoretical value; and 5) slowly stirring and cooling to 20 DEG C. The printable hot stamping layer is characterized by good printing effect after hot stamping, environmental protection and the like.

Description

technical field [0001] The invention relates to a printable anodized aluminum hot stamping layer and a preparation method thereof. The anodized aluminum hot stamping layer is a special polymer material, in particular to a polymer of a printable anodized aluminum hot stamping layer for packaging anti-counterfeiting Materials and preparation methods. Background technique [0002] Nowadays, the printing industry has higher and higher requirements on the appearance of printed products, and post-iron printing is a top technology, and the substrates used have specific requirements. Ordinary anodized aluminum hot stamping film uses a wax-based release agent, so the surface tension of the hot stamping layer is too small, making it difficult to print. The use of printable anodized aluminum hot stamping layer polymer materials to produce anodized aluminum hot stamping film does not require the use of wax-based release agents, and the surface tension of the hot stamping layer of the p...
