Embodiment 1

[0044] Embodiment 1: A low-migration printing material. The printing material is made of the following raw materials in parts by weight: 1 kg of polyethylene wax, 5 kg of initiator and 60 kg of binder.

[0045] Wherein, initiator is TX-β-CD initiator;

[0046] The connecting material is tung oil.

[0047] The preparation method of the above-mentioned low-migration printing material includes the following steps: mix the binder, polyethylene wax, and initiator in the dispersant, disperse at a speed of 300 rpm, and stir for 30 minutes at a temperature of 50°C. , Grind for 15 minutes under a pressure of 0.5MP; finally cool to room temperature and filter.

Embodiment 2

[0048] Embodiment 2: A low-migration printing material. The difference from Embodiment 1 is that the raw materials and dosage of the printing material are different. For the dosage of the printing material, see Table 1 for details.

[0049] The above printing material is made of the following raw materials in parts by weight: polyethylene wax 1kg, initiator 5kg, binder 65kg, pigment 5kg, filler 1.5kg and defoamer 1kg.

[0050] Wherein, initiator is TX-β-CD initiator;

[0051] The connecting material is ink oil;

[0052] The pigments are 2kg titanium dioxide and 3kg iron blue, and the powder particles of titanium dioxide and iron blue are controlled at 0.45±0.05μm;

[0053] The filler is food grade calcium carbonate;

[0054] The defoamer is DSA-5 defoamer.

[0055] The preparation method of the above-mentioned low-migration printing material comprises the following steps:

[0056] 1) First, pre-mix food-grade calcium carbonate and titanium dioxide, and then grind at 50°C a...

Embodiment 3-7

[0058] Embodiment 3-7: a low-migration printing material. The difference from Example 2 is that the raw materials and dosage of the printing materials are different. For the raw materials and dosage of the printing materials, see Table 1 for details.

[0059] Raw material components and corresponding dosage (kg) of the embodiment 1-8 of a kind of low migration printing material of table 1

Abstract

The invention relates to the technical field of environment-friendly printing materials, and particularly discloses a low-migration printing material, a food-grade packaging printing paper box and a preparation method of the low-migration printing material. The printing material comprises 1-3 parts of polyethylene wax, 5-10 parts of an initiator, 60-70 parts of a binder, 0-15 parts of a pigment and 0-5 parts of other auxiliary agents. The initiator comprises an Irgacur cationic photoinitiator, an I-250 iodonium salt cationic photoinitiator, a TX-beta-CD initiator or a TX-GA initiator. The preparation method comprises the following steps: mixing the pigment, the binder, the other auxiliary agents, the polyethylene wax and the initiator, conducting stirring for 30-60 minutes, and conducting grinding for 15-20 minutes; and conducting cooling to room temperature and then conducting filtering. The printing material disclosed by the invention has the advantages of low migration, high adhesive force and high curing speed; and the prepared food-grade packaging printing paper box can be in direct contact with food, does not need to be packaged again, and is very convenient and safe.

Description

technical field [0001] The invention relates to the technical field of environmental protection printing materials, in particular to a low-migration printing material, a food-grade packaging printing carton and a preparation method thereof. Background technique [0002] After the ink is dried and solidified on the substrate to form an ink layer or ink film, due to friction, ink layer not fully cured, poor adhesion, etc., it is transferred to other places through contact or scratching, causing pollution, which is called "Ink Migration". At present, it can be said that it is impossible for any ink to completely achieve zero migration, only the difference in the amount of migration. [0003] The main components of UV ink include photocurable prepolymers, reactive monomers, photoinitiators and pigments. Compared with solvent-based inks, UV inks are widely used for packaging and label printing due to their own advantages, such as short curing time, stable printing quality, high...
