Description
Technical field
The present invention relates to a kind of cigarette with the production method of aluminum coated inner lining body paper, particularly a kind of can be as the production method of the body paper of aluminizing of cigarette inner packing.
Background technology
Cigarette is through the special of single face coating and supercalendering ornamenting with the aluminum coated inner lining body paper, is used for the cigarette inner packing, is a kind of green material of aluminum foil backing paper in the cigarette substitute packing; Relatively non-environment-friendly type aluminum foil composite paper, cigarette has following clear superiority with aluminum coated inner lining paper paper:
(1) paper surface is smooth clean, and glossiness is high, economize on resources (the aluminium consumption only for aluminum foil composite paper 1/300), easily degrade and recycle;
(2) can utilize the directly false proof shading of processing of aluminizer, and be adapted to multiple mode of printing;
(3) because aluminium coated is thin, its plasticity is basic identical with art post paperboard with folding resistance, and package speed and tobacco bale molding effect are ideal;
(4) directly plating papers does not need to use the adhesive that contains VOC in process of production, has further improved the environmental protection grade of this material;
Cigarette depends on the cigarette quality of aluminum coated inner lining body paper to a great extent with the quality of aluminum coated inner lining paper, and this just requires to have following performance as the cigarette of cigarette inner packing with the aluminum coated inner lining body paper:
The one, free from extraneous odour, unharmful substance;
The 2nd, folding property is good, and is higher to the folding property requirement of paper owing to cigarette is used for packing with the body paper of aluminizing, and requires paper to rebound after folding little;
The 3rd, other requirements of the subsequent handling that is fit to aluminize.
Summary of the invention
The object of the invention is to overcome the deficiency that prior art exists, be fit to do the cigarette of cigarette inner packing with the production method of aluminum coated inner lining body paper and provide a kind of.
For achieving the above object, technical scheme of the present invention is: the described cigarette production method of aluminum coated inner lining body paper, the method comprises the steps:
A. body paper is manufactured paper with pulp: long fiber and staple fibre are pulled an oar respectively, and beating degree is 20-40 ° of SR; Then by long fiber: staple fibre is the weight proportion of 20-80:20-80, and adding sizing agent 0.1-1.0%, after slagging-off, add again calcium carbonate, consumption is regulated according to becoming paper ash to divide, and adding high molecular polymer 0.01-0.1%, the excess pressure sieve adds retention agent 0.01-0.5% again after mixing after sieving, and enters head box by current stabilization is laggard, carry out top sizing through wet end dehydration, squeezing, leading portion drying, adding Cypres, resin added is 0.5-2.5g/m
2, ash content is controlled at 5%-15%, back segment is dry, batch body paper behind the soft calendaring, above listed ratio is all with respect to the percentage by weight of paper pulp weight;
B. coating preparation: calcium carbonate and china clay summation are 100 Unit Weights, other paint ingredient ratio all is weight proportions of relative these 100 parts of Unit Weights, used chemicals all calculates with oven-dry weight, and its proportioning is calcium carbonate: china clay=30-70:30-70; Latex 10-20, water retention agent 0.1-0.8, lubricant 0.1-1.5; Solid content is 58-75% in the coating, and viscosity is controlled at 500-1500cps;
C. coating: the coating of b step preparation is carried out one coating at least on the body paper that is made by a step, total coating weight 5-30g/m
2
D. press polish: through the paper of c step coating during in the superpressure press polish by at least one press polish zone, the press polish zone is comprised of a hard roller and a soft roller, pressure is 50-400KN/m, roll surface temperature is 50-250 ℃.
Described sizing agent is a kind of in alkyl ketene dimer or the alkenyl succinic anhydride;
Described high molecular polymer is a kind of in polymine or the polyacrylamide;
Described retention agent is a kind of in silica gel or the bentonite;
Described Cypres is the mixture of starch or starch and acrylate copolymer or in starch and the alkyl ketene dimer mixture any one;
