Embodiment 1

[0015] A gravure printing ink for PET substrates, the ink raw materials and proportions are: 30% of the ink weight ratio of titanium dioxide, 28% of resin, 9% of adhesion promoter, 0.5% of dispersant, The organic mixed solvent is the balance. Wherein the organic mixed solvent is composed of 42% dimethyl carbonate, 42% ethyl acetate, and 16% n-propanol in the mass ratio of the organic mixed solvent.

[0016] The above-mentioned preparation method of the gravure printing ink that is used for PET base material is as follows:

[0017] (1) Configure a mixed solvent, the proportion of the mixed solvent is 32.5% by weight of the ink, and the specific composition of the mixed solvent is as follows: the amount of dimethyl carbonate is 42% of the mass ratio of the mixed solvent, ethyl acetate is 5% of the mass ratio of the mixed solvent 42%, n-propanol is 16% of the mixed solvent mass ratio.

[0018] (2) Dissolve the resin with a weight ratio of 28% of the ink in the above mixed solve...

Embodiment 2

[0024] As described in Example 1, the difference is that the ink raw materials and the proportion are: accounting for 11% of the ink weight ratio of organic pigments, 43% of resin, 10% of adhesion promoter, 1% of dispersant, organic The mixed solvent is the balance. Wherein the organic mixed solvent is composed of dimethyl carbonate, 30% ethyl acetate, and 14% n-propanol which occupy an organic mixed solvent mass ratio of 56%.

Abstract

The invention discloses gravure printing ink for a poly(ethylene terephthalate) (PET) base material and a preparation method for the gravure printing ink, and aims to provide ink having the advantages of good fluidity, high adhesion, high gloss, simple and feasible preparation method, safe use and environment friendliness, and a preparation method thereof. The ink comprises the following components: an organic pigment or an inorganic pigment, resin, an adhesion promoter, a dispersing agent and the balance of organic mixed solvent. The ink is prepared by the following steps of: mixing dimethyl carbonate, ethyl acetate and n-propyl alcohol to obtain a mixed solvent, and dissolving the resin; and mixing with the organic pigment or the inorganic pigment, stirring and dispersing to obtain a semi-finished product of color paste, fully grinding on a sand mill, adding the adhesion promoter and the dispersing agent, fully stirring, and filtering off components of which the fineness is more than 15mu m by using a filtering machine to obtain the gravure printing ink for the PET base material.

Description

technical field [0001] The invention relates to an ink and a preparation method thereof, in particular to a concave ink used for PET substrates [0002] Plate printing ink and its preparation method. Background technique [0003] At present, people's pursuit of commodity outer packaging is not limited to its aesthetics, but more and more attention is paid to the safety performance and environmental protection performance of its packaging. At this stage, the outer packaging of commodities mostly uses PET film composite printing; the ink solvents used are mostly toxic benzene solvents such as benzene, toluene, xylene, etc., and the ink solvents using this solvent have a large amount of residual solvents, especially benzene The content exceeds the standard. Long-term exposure to this toxic solvent will cause great damage to the human body, especially the nervous system. my country stipulates in the light industry standard QB / T2929-2008 that the sum of benzene, toluene and xy...
