Embodiment 1

[0036] (1) A micron-sized silicon oxide powder (frosting powder) is evenly dispersed by ball milling in a composition containing aqueous acrylic emulsion, polyvinyl alcohol, carboxymethyl cellulose, and water to form a coating with a frosting effect mixture, and then disperse a certain amount of optically variable pigments into the paint mixture, and disperse and mix evenly to obtain a water-soluble optically variable frosted paint;

[0037] The quality of each component of water-soluble optically variable frosted paint is:

[0038] Water-based acrylic emulsion 45kg;

[0039] Polyvinyl alcohol 3kg;

[0040] Carboxymethyl cellulose 3kg;

[0041] Silicon oxide powder 8kg;

[0042] 20kg of water;

[0043] 10 kg of powdery optical variable pigments, the fineness of optical variable pigments is 30 μm.

[0044] Under normal circumstances, the silicon oxide powder added when making frosted paint is nano-scale or smaller micron-scale, the general particle size is below 2 μm, and ...

Embodiment 2

[0054] (1) In a composition containing epoxy acrylate photosensitive resin, tripropylene glycol diacrylate, propoxylated trimethylolpropane triacrylate, monomaleimide resin, methylethanolamine, add A small amount of photoinitiator, dispersant and leveling agent uniformly disperses silicon oxide powder and optically variable pigments into the composition to form an ultraviolet light-curable frosted coating that can produce optically variable effects.

[0055] The ratio of each component of the UV-curable light-variable matte coating is:

[0056] Epoxy acrylate photosensitive resin 32kg

[0057] Tripropylene glycol diacrylate 15kg

[0058] Propoxylated Trimethylolpropane Triacrylate 15kg

[0059] Monomaleimide resin 5 kg

[0060] Wax modified silica powder 12kg

[0061] Photoinitiator 5 kg

[0062] Optical variable pigment 8kg

[0063] Dispersants and leveling agents are commercially available products commonly used in the industry in appropriate amounts to adjust the per...

Embodiment 3

[0073] (1) Add a small amount of dispersant and leveling agent to a composition containing epoxy acrylate prepolymer, tripropylene glycol diacrylate, polyurethane acrylate, and polyethylene glycol acrylate, and mix well. Pre-polymerize at room temperature for more than 24 hours to form a liquid composition coating suitable for electron beam curing. Add the frosting powder (fumed silicon oxide) and optical variable pigment in parts by weight, first pre-disperse with a high-speed disperser to eliminate the large particles of the grinding powder The emulsifying machine emulsifies and disperses, so that the frosting powder is fully dispersed in the liquid composition coating to form a homogeneous body. That is, an electron beam-cured frosted paint capable of producing light-changing effects is obtained.

[0074] The ratio of each component of the optically variable electron beam cured frosted coating is:

[0075] Take 35kg of epoxy acrylic acid prepolymer

[0076] Tripropylene g...

Abstract

The invention relates to metalized grinding paper with the optical variability effect and a preparation method thereof, and belongs to the field of packing materials and decorative materials. The metalized grinding paper with the optical variability effect comprises a paper base material, an optical-variability grinding layer and an aluminum coating layer. The metalized grinding paper has the color rendering effect due to interference of received light of an angle-dependent optical effect light interference layer along with different viewing angles or change of the illumination angle of a light source under the illumination of light rays. The paper is recoverable and degradable, has the fine and vivid grinding effect, and the thick metal texture, and the anti-counterfeiting performance of the metalized grinding paper is greatly improved due to combination of grinding and the optical variability effect.

Description

[0001] technical field [0002] The invention relates to a frosted aluminized paper with optical change effect and a preparation method thereof, belonging to the field of packaging materials and decorative materials. Background technique [0003] Vacuum aluminum-coated paper is a green and environmentally friendly packaging material. It can be used as a packaging material in various fields after printing. It has a noble and elegant effect and is deeply loved by consumers. Vacuum aluminum-coated paper, when printing graphic information, if you want to obtain printed products with rich texture, strong three-dimensional effect, crisp lines and bright colors, you generally need to use screen printing. However, due to the thick ink layer of screen printing, more than 30 μm, it is not suitable for printing patterns with fine lines. Compared with offset printing, screen printing has a low printing speed and is not suitable for printing large quantities of packaging materials. In a...
