Abstract
The invention relates to a producing method of firecracker paper as featured as hand-made paper mechanically produced. After bamboo pulp and fiber material of waste paper pulp are crushed and mixed to obtain mixture, direct red is added to the mixture, and urea resin or cationic PEI (polyethyleneimine) is added as dyeing auxiliary; swelling agent and flame retardant are added to firecracker paper pulp in the pulp grinding section; according to actual production conditions, the firecracker paper is produced through raw waste paper pulp and bamboo pulp ratio adjustment, pulp grinding control, pressing phase roll press adjustment and cylinder drying. Compared with the traditional firecracker paper mechanically produced, the firecracker paper has tightness decreased by 15%, tensile strength increased by 20% and colorimeter-measured redness increased by more than 30%; the problem that the firecracker paper mechanically produced is insufficiently red, fails to be completely broken after set off and becomes black is solved.
Description
Technical field
The present invention relates to a kind of preparation method of firecracker paper.
Technical background
Firecracker paper transfers in the process of mechanization production in pure manual production, often have that color is bright-coloured not, firecracker paper is broken not after firecrackers explosion not to reach after the red celebrating effect in full ground and firecrackers explosion the problems such as firecracker paper blackout, although Mechanical Method produces firecrackers body paper can improve output, but the problems referred to above make high-end customer still favor the firecracker paper produced in original manual method, and the firecracker paper of manual production yields poorly, do not reach the current market demand far away.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of Mechanical Method that adopts to prepare the preparation method with the firecracker paper of manual production firecracker paper characteristic.
The present invention solves the problems of the technologies described above taked technical scheme: a kind of preparation method of firecracker paper, comprises the following steps:

(3) the blended fiber raw material after dyeing is carried out defibrination, mass fraction is that 3% ~ 5% slurry concentration enters defibrination workshop section, before fiberizer, online interpolation leavening agent and fire retardant, the mass fraction of leavening agent addition is 0.3% ~ 0.5% of oven dry stock, and the mass fraction of fire retardant addition is 3% ~ 5% of oven dry stock;
(4) pressurized screen removal of impurities is entered after defibrination;
(5) slurry that step (4) obtained injects destroies forebay, the wet end then entering paper machine is shaping, squeezing, dry, rewinding and after cutting, obtain the firecracker paper with hand-made paper characteristic that Mechanical Method is produced.
Preferably, described in step (1), before mixing with secondary stock, bamboo pulp beating degree is 17 ~ 22 ° of SR;
Preferably, described in step (1), secondary stock and bamboo pulp mass ratio are 70%:30%;
Preferably, described in step (2), bright red direct dyes are bright red 4BS, and dyeing auxiliaries is polymine;
Preferably, described in step (2), the mass fraction of bright red 4BS addition is 0.8% of oven dry stock, stablizes 7 minutes, and the mass fraction of polymine addition is 0.5% of oven dry stock, stablizes 6 minutes;
Preferably, leavening agent described in step (3) is alkylamide imidazoline quaternary amine, and fire retardant is phosphoguanidine;
Preferably, after defibrination described in step (3), beating degree is 28 ~ 32 ° of SR;
Preferably, described in step (4), pressurized screen is twin drum pressurized screen;
Preferably, described in step (5), pressure roller linear pressure is 60kPa;
Preferably, described in step (5), drying section uses 10 drying cylinders, and front 5 drying cylinder steam pressures are 0.3MPa, and rear 5 drying cylinder steam pressures are 0.2MPa.
The problem that the present invention runs in conjunction with the mechanization production of firecracker paper, by dyeing auxiliaries, leavening agent and fire retardant add in firecracker paper paper pulp, and it is actual to combine production, by adjusting the raw material secondary stock of firecrackers body paper and the proportioning of bamboo pulp, the control of defibrination, the mode that the adjustment of the pressure roller pressure in squeezing stage and drying cylinder are dried, the firecracker paper that the firecracker paper prepared is produced with traditional Mechanical Method compares, tightness reduces by 15%, tensile strength improves 20%, color difference meter is measured redness and is improved more than 30%, thoroughly solve the color that Mechanical Method firecracker paper runs into scarlet not, can not the problem of completely broken and paper blackout after explosion.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention will be further described:
(1) secondary stock and bamboo pulp mixing, its mass ratio is 70%:30%, and wherein bamboo pulp beating degree is 20 ° of SR, obtains blended fiber raw material;
(2) add bright red 4BS direct dyes at slurry mixing pit, the mass fraction of 4BS addition is, after 0.8% of oven dry stock, 7 minutes, add polymine, and the mass fraction of polymine addition is 0.5% of oven dry stock, keeps 6 minutes;
(3) the blended fiber raw material after dyeing is carried out defibrination, mass fraction is that 4% slurry concentration enters defibrination workshop section, before fiberizer, be 0.3% of oven dry stock according to the mass fraction of alkylamide imidazoline quaternary amine addition, the mass fraction of phosphoguanidine is 4% of oven dry stock, both is added online in slurry with measuring pump;
(4) after defibrination, beating degree is 30 ° of SR, and then mixed slurry enters the removal of impurities of twin drum pressurized screen;
(5) slurry step (4) obtained injects destroies forebay, and the wet end then entering paper machine is shaping; Squeezing, pressure roller linear pressure is 60kPa; Drying, uses 10 drying cylinders, and front 5 drying cylinder steam pressures are 0.3MPa, and rear 5 drying cylinder steam pressures are 0.2MPa; Rewinding and after cutting, obtains the firecracker paper with hand-made paper characteristic that Mechanical Method is produced.
Emphasis of the present invention considers and adds dyeing auxiliaries, on the mixed slurry that ACID DYES can better be attached to based on secondary stock; Also replace the secondary grinding pulp grinder in traditional handicraft with pressurized screen, energy consumption reduces greatly, and impurity-eliminating effect is excellent, makes paper strength larger; In process route, by accurately controlling the moisture of paper, regulating the steam consumption of drying cylinder, realizing efficiency and maximizing; Adding leavening agent makes firecracker paper tightness reduce, and firecrackers is more easily scatter when explosion, and every layer of firecracker paper in firecracker cylinder is all scattered, reach fullly red celebrating effect; Add the effect that fire retardant makes firecracker paper reach high temperature resistant and fire-retardant, the problem that after avoiding firecrackers explosion, firecracker paper turns black.
The firecracker paper that the present invention adopts Mechanical Method to produce, avoid that traditional Mechanical Method produces that the color that runs into of firecracker paper is bright-coloured not, firecracker paper is broken not after firecrackers explosion, not reach after the red celebrating effect in full ground, firecrackers explosion the problems such as firecracker paper blackout, Mechanical Method is made to produce firecracker paper while raising output, product reaches the same characteristic of manual production firecracker paper, meets the demand of high-end customer.
