20-30 parts of EVA resin liquid, 2-4 parts of MP resin liquid, 22-32 parts of rutile titanium dioxide, 0.1-0.5 parts of fumed silica, 1-3 parts of phosphoric acid ester, 10-12 parts of chlorinated polypropylene, 18 -20 parts of ethyl acetate, 4-6 parts of cyclohexane, 3-6 parts of butyl acetate;

Preferably, the ester-soluble printing composite ink consists of the following components by weight:

26 parts of EVA resin liquid, 3 parts of MP resin liquid, 28 parts of rutile titanium dioxide, 0.5 parts of fumed silica, 2 parts of phosphoric acid ester, 12 parts of chlorinated polypropylene, 19 parts of ethyl acetate, 5 parts of cyclohexane, 4.5 parts butyl acetate.

Ink of the present invention has the following advantages:

1. Does not contain benzene and ketone, and has little solvent residue, which meets the national food hygiene requirements;

2. Excellent printability, able to adapt to printing at different speeds of various gravure rotary printing machines;

3. Excellent ink rotation, can perfectly reproduce all levels of printing;

4. Excellent composite performance, strong composite strength can be obtained for various composite films (such as PP, PE) and various composite processing methods (such as dry composite, solvent-free composite).

【Detailed ways】

The present invention will be described in further detail below in combination with specific embodiments.

Embodiment one: get the following components by weight percentage: 26 parts of EVA resin liquid, 3 parts of MP resin liquid, 28 parts of rutile titanium dioxide, 0.5 part of fumed silica, 2 parts of phosphoric acid ester, 12 parts of chlorinated polypropylene, 19 parts 1 part of ethyl acetate, 5 parts of cyclohexane, 4.5 parts of butyl acetate, mix the components and stir evenly to obtain the HRD type ester-soluble printing composite ink of the present invention.

Embodiment two: get the following components by weight percentage: 24 parts of EVA resin liquids, 3.5 parts of MP resin liquids, 30 parts of rutile titanium dioxide, 0.5 parts of fumed silica, 2 parts of phosphoric acid esters, 12 parts of chlorinated polypropylene, 18 parts 5 parts of ethyl acetate, 5 parts of cyclohexane, 5 parts of butyl acetate, mix the components and stir evenly to obtain the HRD type ester-soluble printing composite ink of the present invention.

Embodiment three: get the following components by weight percentage: 30 parts of EVA resin liquid, 2.5 parts of MP resin liquid, 27 parts of rutile titanium dioxide, 0.3 part of fumed silica, 2.2 parts of phosphoric acid ester, 10 parts of chlorinated polypropylene, 16 parts 1 part of ethyl acetate, 6 parts of cyclohexane, 6 parts of butyl acetate, mix the components and stir evenly to obtain the HRD type ester-soluble printing composite ink of the present invention.

The above-mentioned EVA resin liquid can be mixed by 18-22% ethylene vinyl acetate copolymer, 48-54% butyl acetate, and 28-32% ethyl acetate. The above-mentioned MP resin liquid can be formed by mixing 28-32% vinyl chloride isobutyl ether copolymer, 28-32% ethyl acetate, and 36-42% butyl acetate.

The above-mentioned fumed silica is also called fumed white carbon black, English name: Silicon Dioxide, molecular formula: SiO2, it is white fluffy powder, porous, non-toxic, tasteless, pollution-free, high temperature resistant. At the same time, its chemical inertness and special thixotropic properties can significantly improve the tensile strength, tear resistance and wear resistance of rubber products, and the strength of rubber can be improved by dozens of times. Rheological and thixotropic control of liquid systems, adhesives, polymers, etc., used as anti-settling, thickening, anti-sagging additives, reinforcement of HCR and RTV-2K silicone rubber, can be used to adjust free flow And as an anti-caking agent to improve powder properties. Fumed silica is one of the extremely important high-tech ultra-fine inorganic new materials. Because of its small particle size, it has large specific surface area, strong surface adsorption force, large surface energy, high chemical purity, good dispersion performance, thermal resistance, Resistance and other aspects have specific properties. With its superior stability, reinforcement, thickening and thixotropy, it has unique characteristics in many disciplines and fields and plays an irreplaceable role.

The above inks can choose different diluent formulas according to the drying speed required by users:

Quick-drying uses 60% ethyl acetate and 40% butyl acetate as diluent;

Use 40% ethyl acetate and 60% butyl acetate as the diluent for middle drying;

For slow drying, use 20% ethyl acetate and 80% butyl acetate as the diluent.

The present invention is mainly used for the packaging and printing of dry food, cold snacks and other foods, and is not suitable for the packaging of cooking, dipping and oil-containing foods.

The above-mentioned embodiments only express several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but should not be construed as limiting the patent scope of the present invention. It should be pointed out that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent for the present invention should be based on the appended claims.
