Problems solved by technology

[0003] Although the existing cardboard has certain mechanical properties, it does not have anti-counterfeiting properties, which makes its application range relatively limited
Furthermore, its own antibacterial performance is relatively poor, which shortens its service life to a certain extent.

Embodiment 1

[0034] A kind of temperature-changing anti-counterfeiting cardboard, the temperature-changing anti-counterfeiting cardboard includes the anti-counterfeiting base layer, the core paper layer and the anti-counterfeiting surface paper layer from bottom to top;

[0035] The slurry used in the anti-counterfeiting substrate layer is composed of 65wt% hardwood pulp and a residual amount of softwood chemical sulfate pulp;

[0036] The slurry used in the core paper layer is composed of 55% maple chemical mechanical pulp and the residual birch chemical mechanical pulp;

[0037] The slurry used in the security paper layer consists of 20% softwood chemical sulfate slurry and a residual eucalyptus chemical mechanical slurry.

[0038] The security paper layer is quantitatively 27g / m 2 The anti-counterfeiting substrate layer is quantitatively 26g / m 2 。

[0039] A production process for temperature-variable anti-counterfeiting cardboard consisting of the following steps:

[0040] Step 1: Mix the ...

Embodiment 2

[0057] The production process of the temperature-changing anti-counterfeiting cardboard is roughly similar to the technical solution provided in Example 1, the main differences between the two are as follows:

[0058] The slurry used in the anti-counterfeiting bottom layer is composed of 75wt% hardwood pulp and a residual amount of softwood chemical sulfate pulp;

[0059] The slurry used in the core paper layer is composed of 65% maple chemical mechanical pulp and a residual birch chemical mechanical pulp;

[0060] The slurry used in the security paper layer consists of 25% softwood chemical sulfate slurry and a residual eucalyptus chemical mechanical slurry.

[0061] The security paper layer is quantitatively 30g / m 2 The anti-counterfeiting substrate layer is quantitatively 28g / m 2 。

[0062] The amount of warm fiber used is 2.0% of the total mass of the mixed slurry in the pulper of step 1 and step 2, and the mass concentration of the pulp after the crushing treatment in step 1 ...

Embodiment 3

[0074] The production process of the temperature-changing anti-counterfeiting cardboard is roughly similar to the technical solution provided in Example 1, the main differences between the two are as follows:

[0075] The slurry used in the anti-counterfeiting bottom layer is composed of 80wt% hardwood pulp and a residual amount of softwood chemical sulfate pulp;

[0076] The slurry used in the core paper layer is composed of 70% maple chemical mechanical pulp and the remaining birch chemical mechanical pulp;

[0077] The slurry used in the security paper layer consists of 30% softwood wood chemical sulfate slurry and a residual eucalyptus chemical mechanical slurry.

[0078] The security paper layer is quantitatively 32g / m 2 The anti-counterfeiting substrate layer is quantitatively 30g / m 2 。

[0079] The amount of temperature-modified fiber used is 2.5% of the total mass of the mixed slurry in the pulper of step 1 and step 2, and the mass concentration of the slurry after the crush...

Abstract

The invention relates to the technical field of paperboard production, in particular to temperature change type anti-counterfeiting paperboard and a production process thereof. Wherein pulp used by the anti-counterfeiting bottom paper layer consists of 65 to 80 weight percent of hardwood pulp and the balance of needle chemical sulfate pulp; the pulp used by the core paper layer is composed of 55-70% of maple chemimechanical pulp and the balance of birch chemimechanical pulp; the pulp used by the anti-counterfeiting surface paper layer is composed of 20-30% of coniferous wood chemical sulfate pulp and the balance of eucalyptus chemical mechanical pulp; the paperboard produced in the invention has a fast temperature change color development effect and good anti-counterfeiting performance, and the application field of the paperboard is effectively broadened; furthermore, only a small amount of temperature-variable fibers are added into the pulp used by the bottom paper layer and the pulp used by the surface paper layer, so that the purpose of saving the consumption of the temperature-variable fibers is achieved, and the purpose of saving the cost is also achieved; in addition, the prepared paperboard has good antibacterial performance, the service life of the paperboard is effectively prolonged, and meanwhile the quality of the paperboard is guaranteed.

Description

Technical field [0001] The present invention relates to the field of cardboard production technology, specifically a temperature-varying anti-counterfeiting cardboard and its production process. Background [0002] Cardboard is a general term for a type of thick paper between paper and cardboard, weighing about 120 grams per square meter, and is used for postcards, cards, picture book linings, etc. The paper surface of the jam paper is more delicate and smooth, firm and wear-resistant. Depending on the use, there are different characteristics, such as postcard cardboard must have good water resistance, beige cardboard must have appropriate softness, etc. [0003] Although the existing cardboard has certain mechanical properties, it does not have anti-counterfeiting properties, which makes its own application scope relatively limited. In addition, its own antibacterial properties are relatively poor, which shortens its service life to a certain extent. Therefore, providing a tempe...
