Embodiment 1

[0013] Bleached softwood pulp, bleached hardwood pulp, and wheat straw pulp were mixed and refined at a ratio of 30:70. The beating degree was 65oSR, and the wet weight was 3.0g.

[0014] Add the pulp internal sizing agent AKD and cationic starch before going online, the dosage is 1.5% and 1% relative to the absolute dry pulp, the amount of degassing agent is 0.1% relative to the absolute dry pulp, and the amount of wet strength agent is relative to the absolute dry pulp wet strength The dosage of softener is 1.5%, the dosage of softener is 0.01% relative to dry pulp, and the dosage of filler is 11% relative to dry pulp. The paper sheet enters the drying section through the wire section and the press. The idler pressure is set at 100kg / cm, the temperature of the first drying cylinder is 130°C; the pressure of the pressing roller is set at 50kg / cm, and the temperature of the second drying cylinder is set at 100°C. After drying, the paper is calendered in two soft calendering p...

[0016] Bleached coniferous wood pulp and bleached hardwood pulp were blended and refined at a ratio of 35:65. The percussion degree was 70oSR, and the wet weight was 2.7g.

[0017] Add the pulp internal sizing agent AKD and cationic starch before going online, and the dosage is 3% relative to absolute dry pulp and 0.7% relative to absolute dry pulp. The amount of degassing agent is 0.05% relative to absolute dry pulp, the amount of wet strength agent is 1% relative to absolute dry pulp, the amount of softener is 0.02% relative to absolute dry pulp, and the amount of filler is 13% relative to absolute dry pulp. The pulp enters the drying section through the wire section and the press. The idler pressure is set at 80kg / cm, the temperature of the first drying cylinder is 140°C; the pressure of the pressing roller is set at 40kg / cm, and the temperature of the second drying cylinder is set at 110°C. After drying, the paper is calendered in two soft calendering processes. The pres...

Embodiment 3

[0019] Bleached coniferous wood pulp and bleached hardwood pulp were mixed and refined in a ratio of 40:60. The degree of percussion was 75oSR, and the wet weight was 2.2g.

[0020] Add the pulp internal sizing agent AKD and cationic starch before going online, the dosage is 2% and 1% respectively. The amount of degassing agent is 0.15% relative to absolute dry pulp, the amount of wet strength agent is 1.25% relative to absolute dry pulp, the amount of softener is 0.03% relative to absolute dry pulp, and the amount of filler is 16% relative to absolute dry pulp.

Abstract

The invention relates to single-smooth-face raw paper of tipping paper for cigarettes and a production method of the single-smooth-face raw paper. The production method comprises the following processes of pulping, blending pulp, papermaking, squeezing, drying, calendering and the like. A drying process adopts a two-cylinder drying and five-drying-region drying manner including a supporting roller and a compression roller, and adopts a drying process that a drying temperature of a first large cylinder is 130 DEG C to 150 DEG C, a drying temperature of a second large cylinder is 100 DEG C to 120 DEG C, the supporting roller is pressurized for 80kg/cm to 130kg/cm and the compression roller is pressurized for 30kg/cm to 50kg/cm; the front-surface smoothness of the paper is improved, the back-surface smoothness of the paper is maintained and the tightness of the paper is increased; only a manner of sizing in the pulp is adopted and surface sizing is not used. According to the single-smooth-face raw paper of the tipping paper for the cigarettes, prepared by the production process, the front-surface smoothness is more than or equal to 800s and the back-surface smoothness is 40s to 120s. With the adoption of the single-smooth-face raw paper and the production method thereof, the production cost is reduced and the product quality is improved.

Description

technical field [0001] The patent of the present invention relates to a base paper for tipping paper for cigarettes and a production method thereof, in particular to a base paper for tipping paper for single-sided smooth cigarettes and a production method thereof. Background technique [0002] Cigarette tipping paper is a cigarette packaging material used as the outer packaging of the cigarette filter part. The decoration of its surface is processed by the base paper of tipping paper for cigarettes after printing, bronzing and other processes. Since the cigarette tipping paper used as the outer packaging of the filter will directly contact the mouth of the human body, the printing ink has been gradually replaced by non-toxic, safe and hygienic water-based ink. Therefore, base paper for cigarette tipping paper must have certain water resistance and wet strength to meet the performance requirements of human body use and ink printing. On the other hand, the base paper of the ...
