Problems solved by technology

[0005] Due to the flaky structure, surface electronegativity and large specific gravity of pearlescent pigments, if they are simply mixed and added to paper or on the surface of paper, the retention rate of pearlescent pigments in paper will be low, and the distribution on paper surface will be uneven. Technical quality problems such as poor bonding with paper fibers
The low retention rate leads to the need to add more pearlescent pigments and the loss of pearlescent pigments will affect the paper machine making system; uneven distribution will also lead to the use of more pearlescent pigments, which will increase the cost; poor bonding with paper fibers means pearlescent pigments are easy to It falls off from the paper surface, affecting the anti-counterfeiting effect and the quality of the paper
[0006] At present, the use of pearlescent pigments in anti-counterfeiting cigarette paper has not been disclosed or reported

Embodiment 1

[0030] The average particle size of the pearlescent pigment is selected to be about 5 microns, and the dosage of the pearlescent pigment is 0.0001g / m 2 . The chemical pretreatment method of pearlescent pigment is to add 100 parts of water and 2 parts of carboxymethyl cellulose in the pretreatment tank according to the mass parts, and then add 1 part of pearlescent pigment and 0.02 part of sodium hexametaphosphate after stirring and dissolving, and stir at room temperature for 90 The method of adding pearlescent pigments is to add the pearlescent pigment suspension measured according to the dosage requirements into the surface sizing agent preparation device, mix evenly with the surface sizing agent, and implement the surface sizing on the front of the cigarette paper according to the surface sizing process. Glue, so that the pearlescent pigment can be evenly distributed on the front of the cigarette paper. Effect test: under a strong point light source, evenly distributed fin...

Embodiment 2

[0032] The average particle size of pearlescent pigments is selected to be about 2000 microns, and the amount of pearlescent pigments is 0.2g / m 2 . The chemical pretreatment method of pearlescent pigment is to add 100 parts of water and 1.2 parts of quaternary ammonium cationic starch to the pretreatment tank according to the mass fraction, heat up to 90°C for gelatinization, and then add 1 part of pearlescent pigment and hexabia Sodium phosphate 0.01 part, stirring at residual temperature for 50 minutes; the addition method of pearlescent pigment is to add the suspension of pearlescent pigment measured according to the dosage requirements into the slurry forming tank that has been beaten, and stir with the agitator in the slurry forming tank to mix the pearlescent pigment The pigment and the fiber slurry are evenly mixed, and then the papermaking process is carried out, so that the pearlescent pigment is added to the cigarette paper. Effect test: The pearlescent pigments are...

Embodiment 3

[0034] The average particle size of the pearlescent pigment is selected to be about 500 microns, and the dosage of the pearlescent pigment is 0.03g / m 2 . The chemical pretreatment method of pearlescent pigments is to add 100 parts of water and 1.5 parts of quaternary ammonium cationic starch to the pretreatment tank according to the mass fraction, heat up to 90°C for gelatinization, and then add 1 part of pearlescent pigment and hexabia Sodium phosphate 0.01 part, stirring at residual temperature for 60 minutes; the addition method of pearlescent pigment is to add the pearlescent pigment suspension measured according to the dosage requirement into the slurry forming tank that has been beaten, and stir with the agitator in the slurry forming tank to mix the pearlescent pigment The pigment and the fiber slurry are evenly mixed, and then the papermaking process is carried out, so that the pearlescent pigment is added to the cigarette paper. Effect test: the pearlescent pigment par...

Abstract

The invention discloses pearlescent pigment anti-fake cigarette paper and a manufacturing method thereof. Visually-visible pearlescent pigments are uniformly distributed on the front or on the front and the back of the pearlescent pigment anti-fake cigarette paper, and have scattered twinkling lightspots. The method includes adding the pearlescent pigments after chemical pretreatment into fiber size or filler which is a main raw material for production of the cigarette paper, and executing normal papermaking processes to enable the pearlescent pigments to be added in the cigarette paper; or adding the pearlescent pigments after chemical pretreatment into a surface sizing agent, and forming a pearlescent pigment anti-fake marker on the front of the cigarette paper. By pretreating the pearlescent pigments, the technical quality problem that the pearlescent pigments are low in retention rate, uniform in distribution, poor in binding force and the like is solved; the pearlescent pigments enable the cigarette paper to present pearlescent visual effect in bits and pieces and in various colors, and form the anti-fake marker which is obvious and attractive, so that anti-fake effect of the cigarette paper is realized; the pearlescent pigment anti-fake cigarette paper is manufactured mainly by utilizing existing cigarette paper production processes and equipment, thereby being low in cost.

Description

[0001] technical field [0002] The invention relates to an anti-counterfeit cigarette paper, in particular to a pearlescent pigment anti-counterfeit cigarette paper and a preparation method thereof. Background technique [0003] The representative anti-counterfeiting measures that are simple and feasible for paper are mainly the patented technology of anti-counterfeiting coated white cardboard with colored fibers, that is, the color fibers that have been cut and sorted are dispersed evenly with water, and are selected in the bottom (or core layer) beating section or The flow delivery section of the bottom layer (or core layer) of the paper machine adds colored fibers into the pulp and disperses it evenly to obtain the bottom layer (or core layer) pulp, which is then sent to the paper machine for papermaking together with the surface layer to form the bottom layer ( or core layer) anti-counterfeiting coated white cardboard with evenly distributed colored fibers. The techno...
