Problems solved by technology

However, toluene, methyl ethyl ketone and other solvents have low boiling point, high volatility, and contain aromatic hydrocarbons, which are both toxic and flammable, and are the main sources of environmental pollution.
Traditional gravure plastic inner printing ink is printed on PE film, because PE film is an inert material, it is difficult to print, the light fastness after printing is poor, the gloss is poor, and the adhesion is also poor

Embodiment 1

[0064] The dissolution formula ratio table is as follows

[0065]

[0066]

[0067] The preparation process of A, B, C, and D components is the same. Put the solid resin into ethyl ester and n-propyl ester and mix according to the dissolution formula ratio in the above table. Ethylene copolymer liquid, CLEVA liquid, rosin modified phenolic resin liquid, special polypropylene liquid for extrusion and aldehyde and ketone liquid. The resin solvents in traditional gravure plastic composite inks are benzene and ketones, and now they are all replaced by ester solvents.

Embodiment 2

[0069] Get the ethylene-vinyl acetate copolymer solution of 10% by weight prepared in embodiment 1, the CLEVA solution of 10% by weight, the rosin modified phenolic resin solution of 4% by weight and the rutile titanium dioxide of 15% by weight and mix and drop into Mix and stir in the mixer, the stirring temperature is 20-30°C, the dispersion speed is 1000r / min, and the stirring time is 30min to prepare the mixed material;

[0070] The prepared mixed material is placed in a sand mill and ground at a temperature of 20-30 ° C. The grinding time is determined according to the weight of the material to prepare a color paste;

[0071] 15% by weight of the special polypropylene liquid for extrusion, 5% by weight of the aldehyde and ketone solution prepared in Example 1, and 10% by weight of the filler after sanding with a sand mill and 15% by weight of ethyl acetate Put the ester into the color paste, and disperse at a high speed for 30 minutes at a temperature of 20-30°C to prepar...

Embodiment 3

[0073] Get the ethylene-vinyl acetate copolymer liquid of 20% weight portion prepared in embodiment 1, the CLEVA liquid of 20% weight portion, the rosin modified phenolic resin liquid of 8% weight portion and the rutile titanium dioxide of 25% weight portion mix and drop into Mix and stir in the mixer, the stirring temperature is 20-30°C, the dispersion speed is 1000r / min, and the stirring time is 30min to prepare the mixed material;

[0074] The prepared mixed material is placed in a sand mill and ground at a temperature of 20-30 ° C. The grinding time is determined according to the weight of the material to prepare a color paste;

[0075] Get the 20% weight portion of the special polypropylene liquid for extrusion, the 8% weight portion of the aldehyde and ketone liquid prepared in Example 1, and the 15% weight portion of the filler and the 22% weight portion of ethyl acetate after sanding by the sand mill. Put the ester into the color paste, and disperse at a high speed for...

Abstract

The invention discloses a PE / / composite PE gravure plastic composite ink and a preparation method thereof. The composite ink comprises the following raw materials in percent by weight: an ethylene-vinyl acetate copolymer liquid; a CLEVA liquid; a rosin modified phenolic resin liquid; an aldehyde ketone liquid; a special polypropylene liquid for extrusion compounding; a color powder; a filler; andethyl acetate. The preparation process is simple, the printed pattern by the prepared product is flat, smooth and fine, the printing effect is good, the adhesion fastness is strong, the composite inkis non-combustible and non-explosive, the printing effect is kept lasting, the surface of the ink film is smooth and wrinkle-free, the printing is clear, the ink does not fall off during the use process, and the drying speed is fast, so that the composite ink can be suitable for using in the printing ink fields, and the product performance is improved.

Description

technical field [0001] The invention relates to the technical field of inks, in particular to a PE / / composite PE novel intaglio plastic composite ink and a preparation method thereof. Background technique [0002] PE, the full name of which is Polyethylene, is the simplest structure of polymer organic compound, and the most widely used polymer material in the world today. With the continuous development of our country's economy, PE film is used more and more widely in all walks of life, and it plays a very important role in our life. Now PE / / PE composite films are widely used in glass, steel, electronic products, automobiles, digital products and other industries as surface protection, which can effectively prevent dust from falling in, keep the protected content clean, and avoid contamination during transportation. Lost, scratched, etc. [0003] The traditional gravure plastic inner printing ink is produced by chlorinated polypropylene series resin, which is mainly used i...
