Abstract
The invention discloses nitrocellulose paper for fireworks. Base paper is soaked in a medicament mixing solution and is subjected to specific treatment to prepare the nitrocellulose paper; the water content is between 20 and 30 percent; the base paper is pure cotton fibre paper; according to proportion, concentrated sulfuric acid and concentrated nitric acid are poured into a vessel, are mixed, are stirred and are kept stand to form the functional medicament mixing solution; the functional medicament mixing solution has the nitrifying function on changing the performance of a cotton product; the specific treatment comprises preparation of the functional solution, soaking, washing through clean water, detection by test paper, roasting, drying, sealing and storage; the soaking temperature of the medicament solution is between 30 and 70 DEG C; the soaking time for the base paper is between 10 and 45 seconds; the nitrocellulose paper can be used as paper for the lighting background and invisible covering of stage fireworks and subtitle pattern fireworks, paper for wrapping combined fireworks or an effect drug body of a display shell or paper for a paste ball of a ball shell of the display shell; and by coating technology, the nitrocellulose paper is coated and adhered with a layer of pasty colorful medicament, is coiled into a tube barrel shape or is cut into small sections and is used as an effect barrel of fireworks and an effect body of a display shell ball.
Description
Technical field
The present invention relates to a kind of pyrotechnic device paper, especially have a kind of nitrocellulose paper that is used for fireworks of magic special-effect.
Background technology
At present, domestic firework product is of a great variety with paper, such as kraft paper, fluting board, boxboard, yellow plate paper, enamelled paper, wax light paper, big gun material paper, lead-in wire paper, glassine paper, sand paper etc., above-mentioned with paper have as rolling fireworks cylinder, have as fireworks tr and packing box, what have encloses paper as the fireworks molectron, have as the fireworks safety fuse, what have seals or outer packaging as fireworks, because these paper do not pass through special processing treatment, its combustibility is lower, combustion speed is slow, not only has smog to produce during burning, also has residue to exist, therefore, existing firework product has not met environmental protection requirement, remains from being changed and innovate with paper of fireworks, especially along with the appearance of firework display new variety and new classification, more and more higher for fireworks with the requirement of paper, yet, in the prior art, no matter be ground fireworks or high altitude fireworks display, no matter be stage spraying decoration or shelf moulding fireworks, all new breakthrough do not occur on paper as yet at fireworks.
How solving the problem that prior art exists, make a kind of environment-friendly type fireworks paper that can produce special-effect, is that current fireworks manufacturing is sought gordian technique that need to be resolved hurrily again for a long time, that difficulty is higher.
Summary of the invention
The present inventor has carried out studying repeatedly and attempting to the paper stock material that can be used as the firework product use, wish to develop to make to set off fireworks and produce the environment-friendly type fireworks paper of special role and effect, it is poor with the waterproof and dampproof property of paper to overcome existing fireworks, flammable paper, combustion speed is slow, there is cigarette that residue is arranged, the shortcoming that cost price is high, a kind of physics is provided, chemical stability is good, stable performance, waterproof and dampproof, flammable high, combustion speed is fast, non-environmental-pollution, and a kind of special dreamlike appreciation effect is arranged when having the manufacturing firework display, simultaneously can make the firework effect physical efficiency of parcel that the effect that delays the time of setting off is arranged again aloft, the multiduty function of a paper can also be arranged.Consequently, find to have a kind of paper product of fiber manufacturing to embathe and produce into environment-friendly type fireworks nitrocellulose paper, can achieve the above object, thereby finish the present invention through processing.
For achieving the above object, technical solution of the present invention is:
A kind of nitrocellulose paper that is used for fireworks, comprise body paper, functional agent mixing solutions, its special character is: by body paper through soaking function medicament mixing solutions, flushing with clean water, test paper test, bake drying, pack and make described nitrocellulose paper, its water content is 20-30%, described body paper is textile fibrous paper, described functional agent mixing solutions is that the concentrated nitric acid of 98% the vitriol oil and 68% is poured in the container in proportion and mixed, and leaves standstill after the stirring to form; Various proportion of raw materials value scopes in order to the preparation mixing solutions are: 98% vitriol oil 30%-70% weight part, 68% concentrated nitric acid 30%-70% weight part.
The suitable soaking temperature of functional agent mixing solutions after described the leaving standstill is 30-70 degree, and the soak time of described body paper in the functional agent mixing solutions is 10-45 seconds; Described mixing solutions has the digestive function that changes the cotton paper performance.
Nitrocellulose paper of the present invention can be used as stealth that stage fireworks, caption pattern firework set off and cover with paper, combined firework, display shell effect power parcel with paper, fire works display projectile shell paste ball paper.
The present invention also can apply the colored medicament of viscose glue one deck pasty state and roll into the bobbin shape, or be cut into segment as the effect body in firework effect tube and the fire works display projectile thereon by coating technique.
The present invention compared with prior art, its remarkable advantage and positively effect are:
1, more existing nitro-cotton manufacturing technology has shortened the soak time of cotton products in mixing solutions greatly, and by original immersion 20-40 minutes that need, shortening to only needs to soak the nitrocellulose paper product that just can obtain to be fit to the firework sector application 10-45 seconds.
2, use nitrocellulose paper of the present invention, because of combustion speed ratio common paper fast, slower than bright pearl and powder column, prove through repetition test repeatedly, be used to make fireworks leads, can improve lead-in wire combustion speed and reaching the environmental requirement of little cigarette; Be used to make the background of caption pattern firework, particularly stage fireworks series and other fireworks combinations can make stage set off fireworks to produce the dreamlike effect as the nitro-cotton; On nitrocellulose paper of the present invention, apply the color colored light composition of viscose glue one deck again, roll into the bobbin shape, can roll into a ball fireworks product by the colored fire of processing and fabricating spurting, can be cut into segment and bright pearl again loads in mixture in the combined firework effect tube or in the fire works display projectile, not only can make firework display effect increase new specific dynamic modelling pattern, also can prolong the colour developing incendiary pattern modelling skyborne residence time of effect.
3, nitrocellulose paper of the present invention has satisfied design requirementss such as smokeless, tasteless, no residue, meets the development need of firework industry Development of New Generation fireworks product.
Embodiment
Below, the present invention will be described in more detail by embodiment, but the invention is not restricted to these embodiment.
As is known to the person skilled in the art, be used for the vitriol oil of functional agent mixing solutions of the present invention and concentrated nitric acid and after mixing the cotton products particular procedure than mixing, have the nitrification function that changes the cotton products performance, reach effect smokeless, tasteless, no slag after can making the cotton products burning according to certain volume.
