Problems solved by technology

[0002] UV is the abbreviation of ultraviolet curing in printing. Since UV ink is often used in the printing process, UV ink must be irradiated by ultraviolet light before it can be cured. At present, the golden wrapping paper is exposed to volatile organic compounds (VOCS) after being irradiated by UV lamps. The benzene content in the product will increase exponentially, especially for products with high surface transparency, the benzene content will increase even more after being irradiated by UV light, which will affect the VOCS level of the product, and the produced product will cause harm to the human body

Embodiment 1

[0015] For the golden paint used in the "Blue Ribbon and Yellow Crane Tower" products of Wuhan Cigarette Factory, yellow dye and orange pigment were selected first, and the yellow dye and orange pigment were tested by Agilent 7890A gas chromatograph, and the yellow dye with undetected benzene content was selected for detection and orange paint. Then use the UV drying machine for the selected yellow dye and orange pigment (turn on two UV lamps, each 80W, 0.6g of yellow dye and orange pigment moving speed is 5m / min), after 2 times, use Agilent 7890A gas phase The chromatograph detects VOCS again, and chooses to detect yellow dye and orange pigment whose benzene content is not detected.

[0016] Then mix the slurry. For yellow dye paste, mix and stir yellow dye: methyl ethyl ketone at a mass ratio of 12:88; stirring and adding process: put the weighed methyl ethyl ketone into the mixing tank, stir with an electric frequency disperser, and first adjust the speed to 500 RPM, then...

Embodiment 2

[0020] For the golden paint used in the "Treasure Lanzhou" cigarette package products of Lanzhou Cigarette Factory, yellow dye and orange pigment were selected first, and the yellow dye and orange pigment were tested by Agilent 7890A gas chromatograph, and the yellow dye and orange pigment whose benzene content was not detected were selected for detection. Orange paint. Then use the UV drying machine for the selected yellow dye and orange pigment (turn on two UV lamps, each 80W, 0.6g of yellow dye and orange pigment moving speed is 5m / min), after 2 times, use Agilent 7890A gas phase The chromatograph detects VOCS again, and chooses to detect yellow dye and orange pigment whose benzene content is not detected.

[0021] Then mix the slurry. For yellow dye paste, mix and stir yellow dye: methyl ethyl ketone at a mass ratio of 12:88; stirring and adding process: put the weighed methyl ethyl ketone into the mixing tank, stir with an electric frequency disperser, and first adjust t...

Abstract

The invention mainly discloses a pigment formulation process for a golden product, comprising the following steps: appropriate yellow dye and orange pigment are selected by two-stage screening; a slurry forming technology of the yellow dye paste and the orange pigment paste is carried out; and finally the mixture is blended with a paint to obtain a final golden paint. According to the invention, the content of benzene is not raised after a golden transfer product is illuminated by an UV lamp.

Description

technical field [0001] The invention relates to the field of printing and packaging industry, in particular to a colorant formulation process for gold products. Background technique [0002] UV is the abbreviation of ultraviolet curing in printing. Since UV ink is often used in the printing process, UV ink must be irradiated by ultraviolet light before it can be cured. At present, the golden wrapping paper is exposed to volatile organic compounds (VOCS) after being irradiated by UV lamps. The benzene content will increase exponentially, especially for products with high surface transparency, the benzene content will increase even more after being irradiated by UV light, which will affect the VOCS level of the product and cause harm to the human body. The present inventor has solved the problem that the benzene content of the golden product does not increase after the UV lamp is passed through the selection of the toner and the improvement of the color paste adding and stirri...
