Embodiment 1
[0019] The pharmaceutical raw materials are weighed according to the volume ratio, and the ratio of the selected raw materials and the manufacturing process steps are as follows:
[0020] Get 30 parts by weight of 98% concentrated sulfuric acid, pour 60 parts by weight of 68% concentrated nitric acid into a container and stir and mix to form a solution; get 10 parts by weight of pure cotton paper as the base material of nitrocellulose paper; Soak in a mixed solution with a temperature of 50 degrees. After soaking for 10 seconds, observe the color change. Quickly take it out and put it in a clear water pool to rinse it repeatedly. After testing the pH value with test paper, it is qualified; then dry it, and finally seal it with a film bag. The nitrocellulose paper for fireworks of the present invention can be obtained, and the water content is 20-30%.

[0022] The pharmaceutical raw materials are weighed according to the volume ratio, and the ratio of the selected raw materials and the manufacturing process steps are as follows:
[0023] Get 60 parts by weight of 98% concentrated sulfuric acid, pour 30 parts by weight of 68% concentrated nitric acid into a container and stir and mix to form a solution; get 10 parts by weight of pure cotton paper as the base material of nitrocellulose paper; Soak in a mixed solution with a temperature of 50 degrees. After soaking for 45 seconds, observe the color change. Quickly take it out and put it in a clean water pool to rinse it repeatedly. After checking the pH value with test paper, it is qualified, then dry it, and finally seal it with a film bag. The nitrocellulose paper for fireworks of the present invention can be obtained, and the water content is 20-30%.

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 isused as an effect barrel of fireworks and an effect body of a display shell ball.
Description
technical field [0001] The invention relates to a kind of paper for pyrotechnic devices, in particular to a kind of nitrocellulose paper used for fireworks with magical special effects. Background technique [0002] At present, there are many kinds of paper used in domestic fireworks products, such as kraft paper, corrugated paper, cardboard paper, yellow board paper, coated paper, waxed paper, gun stock paper, lead paper, cellophane, sandpaper, etc. Some of the above papers are used as rolls. To make fireworks cylinders, some are used as fireworks packaging boxes and boxes, some are used as surrounding paper for fireworks assemblies, some are used as fireworks fuses, and some are used as fireworks seals or external packaging. Special processing, its flammability is low, the burning speed is slow, not only smoke is produced when burning, but also residues exist. Therefore, the existing fireworks products do not meet the requirements of environmental protection, and it is nec...
