▎ 摘 要
NOVELTY - Single solvent high-brightness gravure plastic metal ink comprises 10-25 wt.% high molecular weight modified butyl cellulose resin, 15-35 wt.% high brightness high flash metal pigment, 20-45 wt.% ester solvent, 0.5-2 wt.% adhesion promoter, 0.5-1 wt.% metal flatting agent and 0.2-1 wt.% other auxiliary agent. USE - Used as single solvent high-brightness gravure plastic metal ink. ADVANTAGE - The single solvent high-brightness gravure plastic metal ink has improved brightness, metallic glitter effect and flashing effect; and can better meet people's demand for metal brightness to achieve a certain anti-counterfeiting effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing single solvent high-brightness gravure plastic metal ink, comprising (i) mixing 10-25 wt.% high molecular weight modified butyl cellulose resin, 15-35 wt.% high brightness high flash metal pigment, 20-45 wt.% ester solvent, 0.5-2 wt.% adhesion promoter, 0.5-1 wt.% metal flatting agent and 0.2-1 wt.% other auxiliary agent evenly, and passing it through an 80-150 mesh sieve for use; (ii) adding all the high molecular weight modified butyl cellulose resin, 1/10-1/2 of graphene modified polyurethane and 1/10-1/2 of nano-carbon fiber modified vinyl chloride resin liquid into the pre-mixing dispersing cylinder, starting the dispersion machine, adding dispersant and 1/5-1/2 of the ester solvent at a speed of 300-500 minutes, stirring uniformly, adding all the mixed material of step (i), modified silicon antifoaming agent, adhesion promoter and metal flatting agent, allowing to stand for 30-60 minutes, stirring the dispersion machine fully at 300-500 revolutions/minutes to form a pre-dispersed color slurry; (iii) adding the remaining solvent, polyethylene wax paste, other additives, nano-carbon fiber modified chloroacetate resin liquid and graphene modified polyurethane into the pigment paste, turning on the disperser for stirring and dispersing at 300-500 revolutions/minutes for 10-15 minutes, adjusting the viscosity of the ink to make a finished composite ink, when necessary and adding ink to adjust the hue according to customer needs; and (iv) filtering the obtained composite metal ink, returning into the cage at low temperature for 5-10 minutes using an 80-meshes sieve, subjecting to low-temperature vacuum packaging, packaging and placing in storage.
