Nitrocellulose paper for firework

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...

Problems solved by technology

[0004] The inventor of the present invention has repeatedly studied and tried paper raw materials that can be used as fireworks products, and hopes to develop an environmentally friendly fireworks paper that can produce special effects and effects when setting off fireworks, so as to overcome the poor waterproof and moisture-proof properties of the existing fireworks paper, and the flammable and flammable paper. The shortcomings of non-toxic paper, slow burning speed, smoke and residue, and high cost price provide a kind of physical and chemical stability, stable performance, waterproof and moisture-proof, high flammability, fast burning speed, no environmental pollution, and has the ability to There is a special fantasy viewing effect when making fireworks, and at the same time, it can delay the time of the fireworks wrapped in the air, and it can also have a multi-purpose function
