Embodiment 1

[0032] A treatment method for improving the printing performance on the surface of a corrugated box, comprising compounding a layer of modified reinforcement film on the surface of the corrugated box, specifically comprising the following steps:

[0033] (1) Preparation of reinforcing filler:

[0034] a. First add ethanol solution to the reactor, then add divinylbenzene, hydroxyethyl methacrylate, and stabilizer to the reactor, and then continuously stir at a speed of 400 rpm for 1 hour;

[0035] b. Then add nano-silver particles and disodium ethylenediaminetetraacetate to the reactor after operation a, and then ultrasonically treat for 2 hours;

[0036] c. Then add the initiator to the reaction kettle after operation b, heat to keep the temperature in the reaction kettle at 74°C, and increase the pressure in the reaction kettle to 0.23MPa at the same time. The kettle was discharged to normal pressure, and the temperature in the reaction kettle was raised to 82°C, and the hea...

The kettle was discharged to normal pressure, and the temperature in the reactor was raised to 84°C, and the heat preservation treatm...

Embodiment 3

[0072] A treatment method for improving the printing performance on the surface of a corrugated box, comprising compounding a layer of modified reinforcement film on the surface of the corrugated box, specifically comprising the following steps:

[0073] (1) Preparation of reinforcing filler:

[0074] a. First add ethanol solution into the reactor, then add divinylbenzene, hydroxyethyl methacrylate, and stabilizer into the reactor, and then continuously stir at a speed of 440 rpm for 1.5 hours;

[0075] b. Then add nano-silver particles and disodium ethylenediaminetetraacetate into the reactor after operation a, and then ultrasonically treat for 2.5 hours;

[0076] c. Then add the initiator to the reaction kettle after operation b, heat to keep the temperature in the reaction kettle at 78°C, and increase the pressure in the reaction kettle to 0.26MPa at the same time. Unload to normal pressure, and raise the temperature in the reactor to 85°C, and continue the heat preservati...

Abstract

The invention discloses a treatment method for improving surface printability of a corrugated paper carton. The surface of the corrugated paper carton is laminated with a layer of modified reinforcement film. The method specifically comprises the following steps: (1) preparation of reinforcing filler, (2) preparation of modified reinforcement film, and (3) lamination treatment. According to the method, the corrugated paper carton is subjected to special processing treatment, the surface printability of the corrugated paper carton is obviously improved, the waterproof, anti-electrostatic and anti-adhesion characters of the corrugated paper carton are improved, the stability of use is good, and the life is long, so that the method extremely has market competitiveness and production benefit.

Description

technical field [0001] The invention belongs to the technical field of packaging box printing, and in particular relates to a treatment method for improving the printing performance on the surface of a corrugated box. Background technique [0002] Corrugated box is an ordinary paper packaging product that is inseparable from our life and production. The printing quality of corrugated box is not only related to the appearance quality of corrugated box, but also affects the sales prospect of the packaged products and the image of commodity manufacturers. Therefore, how to improve the surface printing effect of corrugated cartons and reduce the cost of carton processing is particularly important. [0003] At present, the conventional carton printing methods mainly include flexo printing, offset printing and screen printing. Flexo printing is to print directly on corrugated cardboard, using water-based ink; offset printing uses indirect printing, that is, the carton surface is p...
