Embodiment 1

[0023] A benzene-free alcohol-soluble environmentally friendly plastic printing ink, composed of organic pigments, antistatic agents, dispersants, adhesion promoters, alcohol-soluble synthetic polyvinylpropional resins (PVB resins) and alcohol solvents, antistatic agents It is Kao 3500 of Japan, the dispersant is L-18 dispersant produced by Kao Co., Ltd. of Japan, and the adhesion promoter is polyethyleneimine. Components and content are: 9.5% benzidine yellow G, 1% antistatic agent, 1% dispersant, 0.5% adhesion promoter, 63% alcohol-soluble synthetic PVB resin, 25% alcohol solvent, all in percent by weight.

[0024] The preparation method of above-mentioned non-benzene alcohol-soluble environmental protection plastic printing ink is as follows:

[0025] (1) Take alcohol-soluble synthetic PVB resin and alcohol solvent according to the ratio of alcohol-soluble synthetic PVB resin and alcohol solvent weight ratio of 40:60, add the two to the reaction kettle, and keep warm for 10...

Embodiment 2

[0030] Embodiment 2: Sky blue non-benzene alcohol-soluble environmental protection plastic printing ink

[0031] As described in Example 1, the difference is that the components and content are: 9% phthalocyanine blue, 1% antistatic agent, 1.3% dispersant, 0.7% adhesion promoter, 65% alcohol-soluble synthetic PVB resin %, 23% of alcoholic solvents, all are percentages by weight.

Embodiment 3

[0032] Embodiment 3: Original red non-benzene alcohol-soluble environmental protection plastic printing ink

[0033] As described in Example 1, the difference is that the components and contents are: brilliant red 6B 10%, antistatic agent 1%, dispersant 1%, adhesion promoter 1%, alcohol-soluble synthetic PVB resin 65%, Alcohol solvent 22%, all are percentages by weight.

Abstract

The no-benzene green plastic printing ink consists of inorganic pigment or organic pigment, antistatic agent, dispersant, adhesion promoter, alcohol soluble synthetic PVB resin and alcohol solvent. The preparation process includes the following steps: dissolving the alcohol soluble synthetic PVB resin in alcohol solvent to form translucent resin solution; mixing the inorganic pigment or organic pigment with the resin solution to form color slurry semi-product; grinding the color slurry semi-product in a sand mill and adding the other components via stirring; filtering and packing to obtain no-benzene green plastic printing ink product. The no-benzene green plastic printing ink is boiling resistant and freezing resistant and may be used in packing milk, wine, seasoning, aquatic product, medicine, etc.

Description

(1) Technical field [0001] The invention relates to a printing ink, in particular to a non-benzene alcohol-soluble environmentally friendly plastic printing ink without harmful substances and a preparation method thereof. (2) Background technology [0002] For a long time, the printing inks in my country's packaging industry have mostly been benzene-soluble gravure plastic film inks, and toluene is a highly volatile toxic substance. During the production and printing of inks and the use of packages printed with such inks, due to the release or residue of a large amount of toluene and xylene, it not only pollutes the environment, but also causes harm to human health. At present, many countries in the world have ordered the prohibition or restriction of use. (3) Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides a benzene-alcohol-soluble environmentally friendly plastic printing ink and a preparation method thereof. [00...
