Problems solved by technology

However, due to the complex process of aluminizing technology, the production cost is high, and because no fiber is added to the stone paper during the manufacturing process, the lining paper after aluminizing has a small stiffness and a large rebound after folding, which is difficult to meet the requirements of modern high-speed cigarette production. Demand (500~800 packs / min)

Embodiment 1

[0026] Add 5.5% polyvinyl alcohol into 70% demineralized water, start stirring and heating, the temperature is 29°C, the speed is 120 rpm, make it evenly dispersed, then raise the temperature to accelerate the dissolution, when the temperature reaches 95°C, keep it for 0.7 hours to Dissolve completely, then lower the temperature, when the temperature drops to 76°C, add 7% defoamer. Then add 8% citronellal and 4% catalyst, raise the stirring speed to 110 rpm, keep the temperature constant for 4.5 hours, finally add 5.5% carbon nanofibers, stir until fully mixed. After the reaction is completed, the PVOH coating is obtained.

[0027] Under a constant unwinding tension of 15N, the roll-shaped stone paper substrate is laid flat, and after preheating to make the surface temperature reach 35°C, a layer of water-based paper is printed on the surface of the substrate paper through a metal anilox roller. Ink, the number of printing roller lines is 50 lines / cm, and the amount of ink is...

Embodiment 2

[0030] Add 6.2% polyvinyl alcohol into 71% demineralized water, start stirring and heating, the temperature is 28°C, the speed is 145 rpm, make it evenly dispersed, then raise the temperature to accelerate the dissolution, when the temperature reaches 93°C, keep it for 0.5 hours to Dissolve completely, and then lower the temperature. When the temperature drops to 75°C, add 3% defoamer. Then add 7% citronellal and 4.8% catalyst, increase the stirring speed to 100 rpm, keep the temperature constant for 2 hours, finally add 8% carbon nanofibers, stir until fully mixed. After the reaction is completed, the PVOH coating is obtained.

[0031] Under a constant unwinding tension of 13N, the roll-shaped stone paper substrate is laid flat, and after preheating to make the surface temperature reach 39°C, a layer of water-based paper is printed on the surface of the substrate paper through a metal anilox roller. Ink, the number of printing roller lines is 45 lines / cm, and the amount of i...

Embodiment 3

[0034] Add 6% polyvinyl alcohol into 72.5% demineralized water, start stirring and heating, the temperature is 31°C, the speed is 100 rpm, make it evenly dispersed, then raise the temperature to accelerate the dissolution, when the temperature reaches 90°C, keep it for 0.8 hours to Dissolve completely, then lower the temperature, when the temperature drops to 77°C, add 4.1% defoamer. Add 5.3% citronellal and 3.7% catalyst, increase the stirring speed to 130 rpm, keep the temperature constant for 4 hours, finally add 8.4% carbon nanofibers, stir until fully mixed. After the reaction is completed, the PVOH coating is obtained.

Abstract

The invention relates to a high-barrier environment-friendly coated lining paper and a manufacturing method thereof, comprising a stone paper layer, an ink layer on the upper surface of the stone paper, and a high-barrier layer on the surface of the ink layer, and has a three-layer structure; the stone The weight of paper substrate is 55~80g / m 2 ; The ink layer is a coating formed after the water-based soybean ink is dried; the barrier layer is a coating formed after the modified polyvinyl alcohol coating is coated on the substrate paper surface and dried; The modified polyvinyl alcohol coating is polymerized by raw materials containing the following weight content: polyvinyl alcohol 4-7%, carbon nanofiber 5-9%, citronellal 3-6%, catalyst 3-7%. Foaming agent 2-7%, demineralized water 70-79%. This lining paper has excellent barrier properties, good stiffness and strength, is environmentally friendly and has low production cost, and can completely replace traditional composite lining paper or aluminized lining paper.

Description

technical field [0001] The invention relates to a high-barrier environment-friendly coated inner lining paper and a manufacturing method thereof, belonging to the technical field of cigarette packaging. technical background [0002] Cigarette lining paper is the paper packed between cigarette sticks and cigarette packs, and its main function is to prevent moisture and preserve fragrance. Cigarette lining papers currently used in the domestic and foreign markets include: 1. Aluminum foil composite lining paper, such as patent application CN1378013A, its production process is simple, and it is mainly made of aluminum foil, base paper and composite glue through composite equipment. Strong resistance, good barrier performance. However, the aluminum foil used is not easy to degrade and recycle, and does not meet the requirements of establishing an environmentally friendly society; 2, aluminum-free coated lining paper, such as patent application CN 1888308A, although the lining p...
