Abstract

The invention relates to a smokeless firework with characteristics of both smokeless and firework and a manufacturing method thereof, which is characterized in that: the product is prepared by mixing nitrocellulose, magnesium-aluminum-cerium alloy, metal titanium and shellac according to a certain proportion, loading into an inner cylinder with an outer cylinder, a grid plate and tail mud at one end, inserting a lead, a sealing head and a cover, and has no smoke during setting off, can fully exert the setting off effect and the ornamental effect of fireworks, reduces environmental pollution, can produce series smokeless fireworks, has simple process and safe setting off, and is suitable for indoor setting off and ornamental.

Description

Smoke less fire cracker and manufacture method

The present invention relates to a kind of both smokelessly, have the smoke less fire cracker and the manufacture method of gorgeous fireworks characteristic again.

So-called fireworks, be the cigarette and fiery general name that pyrotechnic compound is sent when burning, general pyrotechnic compound is made up of oxidant, combustible, luminous agent and adhesive etc., and a lot of medicines can play multiple effect in pyrotechnic compound, all adhesives (as: shellac, claim coating agent which has to be dissolved in alcohol before use C again ₁₆H ₂₄O ₅Deng), be again combustible, major part makes the painted material of flame, (as strontium nitrate SrCO ₃Deng), be again oxidant or combustible simultaneously.And black powder is the mechanical impurity of potassium nitrate, sulphur and charcoal, is the ignition charge and the starting mix of pyrotechnic compound.Firework production (firecrackers and fireworks) has at present developed into the resultant effect of sound, light, cigarette, look, moulding from the single sound, but owing to setting off, produce a large amount of smog, influenced firework display effect and effect is tasted in sight, and contaminated environment, outdoor setting off only be applicable to.

The invention provides that a kind of energy is indoor to be seted off, promptly smokeless, have smoke less fire cracker and the manufacture method of fireworks characteristic again.

To achieve these goals, solution of the present invention is, by reel, make up a prescription, powder charge, insert draw, technology such as strip of paper used for sealing and making, it is characterized in that: mix by a certain percentage with nitrocellulose, mangnesium-aluminium-cerium alloy, Titanium and shellac etc., be incorporated with urceolus, lattice plate and an end and be equipped with in the inner core of tail mud, insert lead-in wire; End socket and strip of paper used for sealing wait product.

Drug ingedient scope (by weight) is: nitrocellulose 75～90%, and mangnesium-aluminium-cerium alloy 4～15%, Titanium 5～15% and shellac 5～10%,

More than 1,4 kind of medicine be the following powder of 80 orders, 2,3 kind of medicine be the following powder of 120 orders.

Optimum composition range (by weight) is: nitrocellulose 78%, and mangnesium-aluminium-cerium alloy 12%, Titanium 10% adds shellac 6%.

The manufacture method of this smoke less fire cracker is characterized in that: getting granularity is following nitrocellulose of 80 orders and following mangnesium-aluminium-cerium alloy, the Titanium of 120 orders, adds the following shellac of 80 orders, evenly standby by above-mentioned percentage mix; In the paper web that urceolus, lattice plate and inner core are arranged, fill out tail mud and build reality, add the hybrid medicine prepared, plug lead-in wire, use the thin paper end socket, on urceolus, stick strip of paper used for sealing product.

The present invention has following advantage: 1. do not have smog when setting off, can give full play to the firework display effect and the sight of fireworks and taste effect, reduce environmental pollution; 2. can produce the series smokeless fireworks, as: Pearl Spring (just like pearl is splashed, white colored ribbon drifts), golden fruit (one scene of having a good harvest, little and big yellow fruit Pentium), butterfly play chrysanthemum (in full bloom as yellow daisy, butterfly dances in the air) etc.; Technology simple, set off safety, be suitable for indoor set off and sight is tasted.

The simple declaration of accompanying drawing:

Fig. 1 is a front view of the present invention.

Fig. 2 is a vertical view of the present invention.

Below in conjunction with accompanying drawing, the present invention is described in detail:

Embodiment: as smoke less fire cracker butterfly play chrysanthemum, the external diameter of inner core is 25 millimeters, and internal diameter is 16 millimeters, and length is 124 millimeters manufacture method:

1. get particle less than 80 purpose nitrocelluloses 39 gram and shellac 3 grams, get particle and restrain less than 120 purpose mangnesium-aluminium-cerium alloys, 6 grams and Titanium 5, mix (7) standby.

2. in the paper web that urceolus (3), lattice plate (5) and inner core (4) are arranged, fill out tail mud (6) and build reality, add the hybrid medicine (7) prepared, plug lead-in wire (1), usefulness thin paper (2) end socket, on urceolus (3), stick strip of paper used for sealing (8) product.As shown in Figure 1, 2.

Claims
