Example Embodiment

[0126] Example 1: Preparation of base paper for tipping paper for cigarettes with an air permeability of 150CU

[0127] 1. Beating:

[0128] The coniferous pulp is beaten by a double-disc mill. The double-disc mill is 4 TF20 type double-disc mills. The first two double-disc mills are cut-off disc mills, and the last two are broom disc mills, with a beating concentration of 75 0 SR, wet weight is 7g, and eucalyptus pulp is decomposed by double-disc milling, and the beating concentration is 20 0 SR, wet weight is 1g;

[0129] Mix the processed softwood pulp and eucalyptus pulp at a weight ratio of 35%:65% to make a combined slurry;

[0130] Add 30% of the total weight of calcium carbonate and 1.4% of the wet strength agent to the combined slurry to make a mixed beating slurry.

[0131] 2. Papermaking:

[0132] Dilute the mixed beating slurry with water to a grid concentration of 0.9% by weight, add 0.5% by weight of dispersant and 1.5% by weight of AKD in turn, pass through the bottom mesh...

Example Embodiment

[0146] Example 2: Preparation of base paper for tipping paper for cigarettes with an air permeability of 200CU

[0147] 1. Beating:

[0148] The coniferous pulp is beaten by a double-disc grinder. The double-disc grinder is 4 TF20 type double-disc grinders. The first two double-disc grinders are cut-off disc grinders, and the last two are broom disc grinders with a beating concentration of 70 0 SR, wet weight is 8g, and eucalyptus pulp is decomposed by double-disc milling, and the beating concentration is 18 0 SR, wet weight is 1g;

[0149] Mix the processed softwood pulp and eucalyptus pulp at a weight ratio of 32%: 68% to make a combined slurry;

[0150] Add 40% of the total weight of calcium carbonate and 1.4% of the wet strength agent to the combined slurry to make a mixed beating slurry.

[0151] 2. Papermaking:

[0152] Dilute the mixed beating slurry with water to a grid concentration of 0.9% by weight, add 0.5% by weight of dispersant and 1.5% by weight of AKD in turn, pass throu...

Example Embodiment

[0166] Example 3: Preparation of base paper for tipping paper for cigarettes with an air permeability of 250CU

[0167] 1. Beating:

[0168] The coniferous pulp is beaten by a double-disc grinder. The double-disc grinder is 4 TF20 type double-disc grinders. The first two double-disc grinders are cut-off disc grinders, and the last two are broom disc grinders with a beating concentration of 65 0 SR, wet weight is 8g, and eucalyptus pulp is decomposed by double-disc grinding, and the beating concentration is 15 0 SR, wet weight is 1g;

[0169] Mix the processed softwood pulp and eucalyptus pulp at a weight ratio of 30%:70% to make a combined slurry;

[0170] Add 50% of the total weight of calcium carbonate and 1.4% of the wet strength agent to the combined slurry to make a mixed beating slurry.

[0171] 2. Papermaking:

[0172] Dilute the mixed beating slurry with water to a grid concentration of 0.9% by weight, add 0.5% by weight of dispersant and 1.5% by weight of AKD in turn, pass throu...

Abstract

The invention discloses a production method and system for flame-retardant self-permeable tipping base paper used for cigarettes. The production method comprises the following steps: S100, beating: beating needle pulp by a double-disc refiner with a beating concentration being 65-750 SR and wet weight being 7-9 g, defibering eucalyptus pulp by the double-disc refiner with a pulping concentration being 15-200 SR and wet weight being 1-2 g, mixing the treated needle pulp and eucalyptus pulp according to a weight ratio of (30-35%): (65-70%) to prepare combined pulp, and adding calcium carbonate accounting for 30-50% of the total weight of the combined pulp and a wet strength agent accounting for 1-1.4% of the total weight of the combined pulp into the combined pulp to prepare a mixed pulpingliquid; S200, papermaking: carrying out papermaking and forming with a vat machine to form uniformly interlaced natural pores; S300, drying: carrying out drying in a plurality of groups of drying cylinders, and carrying out coating with a composite mixture of oxidized starch and acrylic resin via a surface sizing agent applying machine during drying to treat the surface performance of a paper sheet; S400, calendaring: finishing the surface of dried paper via a soft calendaring machine; and S500, printing: printing a flame retardant on the reverse side of the paper by using a photogravure press. With the production method and system for the flame-retardant self-permeable tipping base paper, the prepared tipping base paper has both high air permeability and flame retardant properties, wherein an air permeability variable coefficient is smaller than or equal to 7%, and the rate of automatic extinguishing reaches 100%.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a production method and production system for flame-retardant self-smoke-permeable tipping paper base paper. Background technique [0002] Smoking is an extremely common behavior in daily life. It is not uncommon for a smoker to extinguish the cigarette end in time after smoking the cigarette, causing fire accidents. As people pay more and more attention to the safety of fire prevention and control, people's safety awareness of self-protection is also constantly improving, prompting the tobacco production industry to strengthen the safety of cigarette products themselves, improve the preparation technology of cigarette products, and reduce the fire hazard of cigarette products. Potential safety hazards, to meet the society's development needs for safe and environmentally friendly products. The research and development of flame-retardant base paper for cigarette tipping paper...
