CN103102743B - Plastic ink and preparation method thereof - Google Patents

Abstract

The invention discloses plastic ink which comprises the following components in parts by mass: 15-20 parts of acrylate, 50-80 parts of epoxy resin, 5-10 parts of polyketone resin, 30-70 parts of ethanol, 20-40 parts of isopropanol, 40-60 parts of ethyl acetate, 10-30 parts of titanium dioxide, 4-20 parts of wetting dispersant BYK-19, 10-20 parts of titanium acetoxyacetone, 6-12 parts of chloridized polyolefin and 9-20 parts of methylsilicone oil. The plastic ink disclosed by the has the beneficial effects that a mixed solution containing the methyl, the isopropanol and the ethyl acetate is used as a solvent instead of the traditional benzene solvent, so that the damages to the human body and the pollution to the environment are reduced; and as the three components, namely the epoxy resin, the titanium acetoxyacetone and the chloridized polyolefin are crosslinked to one another to form a three-dimensional meshy structure, and therefore the plastic ink can achieve excellent adhesion force, heat resistance and stability.

Description

A kind of ink used for plastic and preparation method thereof

Technical field

The invention belongs to technical field of ink, be specifically related to a kind of environment-friendly type plastic ink and preparation method thereof.

Background technology

In recent years, along with the market rapid growth of plastic flexible package, the demand of intaglio plate plastic wrapping ink is constantly increased.In prior art, the solvent that China is used for plastic gravure ink is master mainly with benzene class.Although benzene class is the good solvent of resin binder, because benzene class belongs to noxious solvent after all, it has very large harm to operator's health, and its volatilization simultaneously has also caused environmental pollution.In addition, because benzene class belongs to slow curing solvent, very easily remain in dry ink rete, can corrode the food in packaging, produce noxious odor, bring harm to human consumer's health.

Summary of the invention

Technical problem to be solved by this invention is: a kind of intaglio plate plastic wrapping use, environment-friendly type plastic ink are provided.

For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of ink used for plastic, by mass fraction, consists of:

Acrylic resin 15-20 part;

Epoxy resin 50-80 part;

Polyketone resin 5-10 part;

Ethanol 30-70 part;

Virahol 20-40 part;

Ethyl acetate 40-60 part;

Titanium dioxide 10-30 part;

Wetting dispersing agent BYK-19 4-20 part;

Acetic acid acetone titanium 10-20 part;

Chlorinatedpolyolefins 6-12 part;

Methyl-silicone oil 9-20 part.

Described wetting dispersing agent BYK-192 (purchased from: Guangzhou prosperous Chemical trade company limited), according to this content of quality, it consists of: 5-10% mineral dye; 15-30% pigment dyestuff; 4-7% titanium dioxide; 30-50% carbon black; 3-5% effect pigment.

The second technical problem to be solved by this invention, is to provide a kind of preparation method of ink used for plastic.

For solving second technical problem, the technical solution used in the present invention is: a kind of preparation method of ink used for plastic, the steps include:

1) acrylic resin, epoxy resin, polyketone resin are added in the mixed solution being made up of ethanol, Virahol, ethyl acetate, be heated to 30-40 DEG C, be stirred to resin and dissolve completely, make A mixed solution;

2) by wetting dispersing agent BYK-19, acetic acid acetone titanium, chlorinatedpolyolefins, methyl-silicone oil mixing and stirring, make B mixture;

3) A mixed solution is added in shredder and ground, then B mixture is added in shredder, the joining day of controlling B mixture is 2-4h, continues to grind 1-2h after B mixture adds again, and obtains ink used for plastic.

Beneficial effect of the present invention: the present invention adopts the mixing solutions of ethanol, Virahol, ethyl acetate as solvent, has substituted traditional benzene solvent, has reduced harm to human body and the pollution of environment; Adopt epoxy resin, acetic acid acetone titanium, chlorinatedpolyolefins, these three kinds of materials formation tridimensional network that is cross-linked with each other, thus obtain excellent sticking power, thermotolerance and stability.
