Problems solved by technology

[0002] At present, the gravure inks sold on the market are all liquid inks, and the most common gravure inks used for printing plastic films are solvent-based inks. This type of ink itself contains a large amount of organic solvents, and a large amount of organic solvents must be added during use. Solvents, these organic solvents will all be discharged into the atmosphere, causing pollution to the environment

Embodiment Construction

[0018] The proportioning of parts by weight of the present invention is as follows:

[0019] 138 resin or petroleum resin 20~50

[0020] Wax 5~60

[0021] EVA resin 10~30

[0022] Dispersant 0.2~2

[0023] Pigment 10~20

[0024] The proportioning in parts by weight is as follows:

[0025] 138 resin or petroleum resin 25~40

[0026] Wax 5~55

[0027] EVA resin 20~30

[0028] Dispersant 0.2~1

[0029] Pigment 10~15

[0030] Wax is a mixture of hydrocarbons with 18-30 carbon atoms. Its main components are linear alkanes, and there are also a small amount of alkanes with individual branched chains and monocyclic naphthenes with long side chains (the total content of the two is less than 20%), such as paraffin and microcrystalline wax.

[0031] Manufacturing method: mix 138 resin or petroleum resin, wax, EVA resin, heat and stir at 80-200°C, then add dispersant and pigment and stir, after the stirring is completed, put it into a molding machine at 100-200°C to form. Can ...

Abstract

The invention relates to a hot melt type solid ink for gravure printing, wherein the hot melt type solid ink comprises, by weight, 20-50 parts of a 138 resin or petroleum resin, 5-60 parts of wax, 10-30 parts of an EVA resin, 0.2-2 parts of a dispersant, and 10-20 parts of a pigment. According to the present invention, the hot melt type solid ink for gravure printing does not contain the organic solvent, and the organic solvent is not added during the printing process, such that no VOC is discharged during the use of the hot melt type solid ink for gravure printing, and the environment protection can be achieved; and the organic solvent is not added during the printing process so as to save the use cost.

Description

technical field [0001] The invention relates to the field of ink, in particular to a hot-melt solid ink for gravure printing. Background technique [0002] At present, the gravure inks sold on the market are all liquid inks, and the most common gravure inks used for printing plastic films are solvent-based inks. This type of ink itself contains a large amount of organic solvents, and a large amount of organic solvents must be added during use. Solvents, these organic solvents will all be discharged into the atmosphere, causing pollution to the environment. Contents of the invention [0003] The object of the present invention is to provide a kind of hot-melt solid ink for gravure printing aiming at the above-mentioned deficiencies at present. [0004] The proportioning of parts by weight of the present invention is as follows: [0005] 138 resin or petroleum resin 20~50 [0006] Wax 5~60 [0007] EVA resin 10~30 [0008] Dispersant 0.2~2 [0009] Pigment 10~20 [00...
