Embodiment 1

[0034] Example 1 Heat-shrinkable film label general-purpose environment-friendly primary color yellow ink

[0035] Weigh 15% of Acoma?-S5600 resin, 5% of nitrocellulose, 12% of three-component vinyl chloride resin, 11% of CAB resin, 11% of EVA resin, 10% of PY12# yellow pigment, 1.5% of polyethylene wax, and gas phase dioxide Silicon 1%, Isopropanol 15%, n-Propyl Acetate 11%, and Propylene Glycol Methyl Ether 7.5%. Stir and mix Acoma?-S5600 resin, nitrocellulose, ternary vinyl chloride resin, CAB resin, EVA resin, PY12# yellow pigment and polyethylene wax in a mixing tank, then put it into a sand mill for grinding until the fineness reaches 10 μm Next stop grinding. When mixing ink, add fumed silica and add ethanol, isopropanol, n-propyl acetate and propylene glycol methyl ether to adjust the viscosity to a thin-walled 3# Zahn cup for 15-25 seconds, then filter and pack.

Embodiment 2

[0036] Example 2 General-purpose environment-friendly primary color red ink for heat-shrinkable film labels Weigh 15% of Acoma?-S5600 resin, 4% of nitrocellulose resin, 8% of ternary vinyl chloride resin, 12% of CAB resin, 14% of EVA resin, and sun-fast scarlet 482110%, polyethylene wax 1.5%, fumed silica 1%, isopropanol 15%, n-propyl acetate 11%, and propylene glycol methyl ether 8.5%. Mix Acoma?-S5600 resin, nitrocellulose, ternary vinyl chloride resin, CAB resin, EVA resin, sunfast scarlet 4821 and polyethylene wax in a mixing tank, then put it into a sand mill for grinding until the fineness reaches 10 μm Next stop grinding. When mixing ink, add fumed silica and add isopropanol, n-propyl acetate and propylene glycol methyl ether to adjust the viscosity to a thin-walled 3# Zahn cup for 15-25 seconds, then filter and pack.

Embodiment 3

[0037] Example 3 General-purpose environment-friendly primary color blue ink for heat-shrinkable film labels, respectively weighed 15% of Acoma®-S5600 resin, 4% of nitrocellulose resin, 14% of ternary vinyl chloride resin, 12% of CAB resin, 14% of EVA resin, and 15:4 Phthalocyanine blue pigment 10%, polyethylene wax 1.5%, fumed silica 1%, isopropanol 14%, n-propyl acetate 6% and propylene glycol methyl ether 8.5%. Stir and mix Acoma?-S5600 resin, nitrocellulose, ternary vinyl acetate resin, CAB resin, EVA resin, 15:4 phthalocyanine blue pigment and polyethylene wax in a mixing tank, then put it into a sand mill for grinding until fine Stop grinding when the degree reaches below 10μm. When mixing ink, add fumed silica and add ethanol, isopropanol, n-propyl acetate and propylene glycol methyl ether to adjust the viscosity to a thin-walled 3# Zahn cup for 15-25 seconds, then filter and pack.

Abstract

The invention discloses color printing ink for printing heat shrink film labels and relates to environmental-friendly ink. The color printing ink comprises the following components: acrylic resin, nitrocotton, VINISOL OH, CAB (Cellulose Acetate Butyrate) resin, EVA (Ethylene Vinyl Acetate) resin, a color pigment, additives and a diluent, wherein the additives are polyethylene wax and fumed silica. Compared with the prior art, the color printing ink for printing the heat shrink film labels, disclosed by the invention, has the advantages that the color printing ink is free of benzene and ketone, resists tetrahydrofuran and can be applied to PVC (Polyvinyl Chloride), PET (Polyethylene Terephthalate), OPS (Oriented Polystyrene) heat shrink film base materials, and after the color printing ink is matched with heat shrink films for printing, the shrink films do not curl and are free of tinting. The products printed by adopting the color printing ink are in line with environment-friendly requirements, are safe and non-toxic and can be recycled; and after printing, the shrink films have very strong capability of resisting alcohol and tetrahydrofuran, thus the problem of the compatibility between the thin films and glue occurring when the thin films are subjected to skin packaging and are glued is solved very well.

Description

technical field [0001] The invention relates to an environmentally friendly ink, in particular to a color ink used for printing heat-shrinkable film labels and a preparation method thereof. Background technique [0002] Heat-shrinkable film label is a film label printed on a film with special ink. During the labeling process, when heated (about 70°C), the shrinkable label will quickly shrink along the outer contour of the container and adhere closely to the container. on the surface of the container. It is easy to use and is very suitable for special-shaped containers. Due to the high transparency of the film itself, the label has bright color and good gloss. Because it must be shrunk during use, there is a disadvantage of pattern deformation, especially for products with printed barcodes, it must undergo strict design and printing quality control, otherwise the barcode quality will be unqualified after the pattern is deformed. [0003] The label of the shrink film sleeve...
