Abstract

The invention provides a kind of color series smoke less fire cracker, its pyrotechnics composition is that the nitrocellulose of platy shaped particle shape variegates the mixture that the light pearl is made, and makes various fireworks such as hand-held, rising, fireworks display then, and is beautiful in colour during this firework display, smoke-free and tasteless has fabulous appreciation effect.

Description

Colour smoke-less series fireworks

The present invention relates to a kind of have multiple color, smokeless, tasteless fireworks.

Fireworks are coloured flame that people seted off in celebrating red-letter day, and the raw material (pyrotechnics composition) that traditional fireworks adopt mainly contains saltpetre, sulphur, charcoal, tinting material, tackiness agent etc., and the flue dust smell is big during this class firework display, and the SO that produces during sulfur burning ₂, H ₂S gas produces murder by poisoning to the people, so has not all put present many countries and regions or put this fireworks less as far as possible, many people also attempt with new raw material substitution tradition pyrotechnics composition, if any the soluble cotton of employing fine powdered and metal, shellac etc. as the raw material (CN91106687) of fireworks, but the firework effect of making is bad, fireworks have sprayed insufficient height when setting off, and pulverous sometimes soluble cotton burning only forms the flame that has no characteristic.

The purpose of this invention is to provide a kind of multiple color that has, fireworks that smokeless, tasteless firework display effect is good and production method thereof.

Solution of the present invention is: adopt sheet or the granular nitrocellulose main raw material as fireworks, also can mix the colorama pearl that one or more metallic compounds that can produce different color are made, pack in the paper web, this paper web and traditional fireworks are similar, back cover mud is arranged at its bottom, lead fire lead-in wire above, several lump together and in addition outer packaging with paper web, can make the smoke less fire cracker of multiple color.

Nitrocellulose:

C ₆H ₇O ₂(ONO ₂) ₃ _nIt is the nitric ether of nitric acid and sulfuric acid and cotton fibre reaction, theoretical nitrogen content 14.14%, Industrial products nitrogen content 10-13%, its nitrogen content is high more, and quick-fried heating power is strong more, its abnormal combustion is rapid, be yellow long flame, produce a large amount of smoke-free and tasteless gases, almost do not have residue, but pulverous nitrocellulose only plays combustion-supporting effect, and effect is bad.

The present invention makes sheet or particulate state with nitrocellulose, pack into behind the cylindrical shell, the impulse force that produces when utilizing burning burns when making sheet or the ascension aloft of granular nitrocellulose, pure nitrocellulose produces beautiful yellow flame, according to the shape difference of grain (sheet), what have resembles the butterfly with different colors that dances in the air, the goldfish as roaming that has, the bouquet that has as soaring, in the night sky, glimmer, smokeless, tasteless, have fabulous appreciation effect.

Colorama pearl with sheet or granular nitrocellulose and other color loads in mixture, and can play the riot of colour, and multicoloured effect loads in mixture as adding nitrate of baryta or cupric oxide, have in the fireworks Huang of emitting green, especially as a peacock flaunting its tail; Add strontiumization and contain thing, then present the in full bloom scene of red chrysanthemum again; This colorama pearl can be made particle separately with traditional fireworks method for making, also can when producing nitrocellulose sheet or particulate mixture be made in the compound adding.

Below be the composition and the content of fireworks raw material of the present invention.

One of raw material:

Sheet or granular nitrocellulose, (wherein the nitrogen content of nitrocellulose is 10-13%, does not add any colorama pearl, at the bottom of this raw material directly installs to and adds mud in the paper web, lead-in wire, envelope paper etc., mainly produces the yellow fireworks effect of waving in the wind when setting off;

Two of raw material:

Getting colorama pearl particulate weight percentage is 1-55%, all the other are nitrocellulose (sheet, the particulate state) mixing of 10-13% for nitrogen content, or film-making again (particle) after the adding colorama pearl powder mixes when producing nitrocellulose, promptly can be used as in the pyrotechnics composition threading paper web and make fireworks.

The compound of colorama pearl produces metal (as strontium, copper, potassium, sodium, magnesium, aluminium, the barium etc.) compound of coloured flame when consisting of potassium perchlorate, magnesium aluminum-alloy powder, polyvinyl chloride, resol and burning, below be colorama pearl embodiment:

Red: potassium perchlorate 18-35%, Strontium carbonate powder 23-28%, magnesium aluminum-alloy powder 18-30%, polyvinyl chloride 12-15%, all the other are resol;

Green: potassium perchlorate 20-25%, cupric oxide 20-25%, magnesium aluminum-alloy powder 18-28%, polyvinyl chloride 10-12%, all the other are resol;

Purple: potassium perchlorate 18-22%, Repone K 10-23%, magnesium aluminum-alloy powder 20-25%, polyvinyl chloride 10-15%, all the other are resol.

The particle of light pearl the light pearl size of fireworks is routinely made.

The method for making of fireworks:, nitrocellulose is made 0.2-0.8cm by above-mentioned material content and the composition of providing ²Wide, thin slice that 0.1-0.3cm is thick or Φ 0.2-0.5cm particle then separately in the paper feed tube, or mix back threading paper web with the colorama pearl, and going to the bottom of paper web sealed with sealing clay, is equipped with lead-in wire above, but paper web several tie together, make different shape.

Below be embodiments of the invention:

One, gets the nitrocellulose of nitrogen content 12.5%, make 0.2-0.8cm ²Thin slice, fireworks are put the medicine method thin slice are placed the paper web center routinely, tube underseal mud (clay) is sealed, go between one and be placed in the thin slice, one is exposed on the cylindrical shell, cylindrical shell sticks color logo outward, can produce the effect of orfe in the play trip during this firework display, is called " big goldfish " fireworks again.

Two, get the nitrocellulose of nitrogen content 13%, make 0.2-0.8cm ²Thin slice, this thin slice accounts for 91% of total charge, get the above-mentioned red light pearl particle 9% that contains Strontium carbonate powder again, nitrocellulose and red light pearl are mixed, the fireworks making method is made tube routinely, these two kinds of existing yellow of raw material have redness again when setting off, and present red tree peony and the disorderly scene of yellow butterfly with different colors, claim " tree peony butterfly with different colors " fireworks again.

Three, get the particle 70% of the nitrocellulose Φ 20mm of nitrogen content 12%, the above-mentioned red light pearl 12% that makes, green light pearl 7%, purple light pearl 11%, with several raw material packing or to load in mixture several paper web recombinants bundled, as a rule install back cover and lead-in wire, present red, green, yellow, the trillium beautiful color that a hundred flowers blossom during this firework display.

Four, get nitrogen content 11.5%, nitrocellulose 58%, in making processes, one or more light pearl raw material 42% is sneaked into, make composite grain (Φ 0.2 particle or the 0.3cm of nitrocellulose and light pearl ²Sheet), make the fireworks method routinely, make various multicoloured fireworks display.

Advantage of the present invention:

1. do not need to use the raw materials such as potassium nitrate, sulphur, charcoal, do not have black smoke when setting off, tobacco pollutes.

2. lucuriant in design, unique style, slabbing or the granular celluloid flame when aloft ascension is caught fire is being waved in the wind, and is rich in characteristic than traditional fireworks.

3. celluloid is preserved and is difficult for the moisture absorption, the danger that does not also have the such easy collision of general black powder to catch fire.

4. manufacture craft is simple, and the workman is not subjected to the harm of dust from flying.

5. can be made into the colored different kinds such as multiple hand-held, rising, fireworks display, the ornamental value height.
