Abstract

The invention discloses a kind of smoke less fire cracker, can make the series smokeless firework product.Its technical characterstic comprises that non smoke produces and fragrant odour when setting off, and it is few to set off the residual dust in back, and security and good stability.

Paper web of the present invention only by paper web low and bottom seal the mud head and constitute, its medicament is formed and is comprised nitro-cotton, ethanol ether solvent, pentanoic etc.Have flame temperature low, can be indoor setting off and characteristics free from environmental pollution, that do not damage HUMAN HEALTH.

Description

Smoke less fire cracker

The present invention relates to fireworks, can spurt the spraying decoration class fireworks that colored spark is viewed and admired for people when especially setting off.

Since fireworks came out, it always produced with smog when setting off, and it is many to set off the residual dust in back, causes environmental pollution, diminishes HUMAN HEALTH.The tradition fireworks exist also that safety coefficient is low, the spy of poor stability falls into, and are inflammable under certain impact, friction or temperature condition, explosive; Be easy to the moisture absorption and generate heat or mouldy, sex change takes place, thereby cause self-destruction or lost efficacy, had a strong impact on product production.Developing and can overcome above-mentioned insufficient firework product, then is that people are long-expected.

Traditional fireworks seal the mud head by paper tube body, upper and lower port usually and the interior medicament of tube is formed, and upper port is sealed the mud head and left the fireworks jet hole, and lead-in wire generally places this hole (referring to Fig. 2).The band jet hole mud head of described upper port has the effect that increases the fireworks jetting height.

The objective of the invention is, design a kind of smoke less fire cracker, it had both kept the appreciation effect of traditional fireworks, when setting off, smokelessly produce again, and than traditional product have set off the back residual dust few, the characteristics of security and good stability.

Technical solution of the present invention is, adopts the paper web of supreme port sealing mud head, can fully be discharged when medicament is seted off and eliminates one of important factor of the generation smog that traditional fireworks exist; The medicament of special preparation of raw material is chosen in employing, makes it both to have had good appreciation effect when setting off, and do not produce smog again, and residue is few, and has the characteristics of security and good stability.

Below adopt the employed professional term of " fireworks production and safety " book (light industry press publishes, the first impression in May, 1988, standard book number 15042.15397), predicate, the present invention is made further specify.

The present invention includes lead-in wire, paper web, medicament.The constructional feature of described paper web is that it only is made of paper tube body (2) and following end closure mud head (1).Medicine component of the present invention (weight percent composition) is:

Nitro-cotton 25-70%; Ethanol ether solvent 14-6%;

Pentanoic 24-4%; Camphor 16-3%;

Graphite 6-1%; Charcoal 8-2%;

Naphthoquinones 2-5%; Potassium perchlorate 3-1%;

Luminous agent 2-8%;

Wherein, the weight percent of ethanol ether solvent composition is dehydrated alcohol 20-80%, anhydrous diethyl ether 80-20%.Described luminous agent can be the mixture of the husky titanium grain with 80-20% of the iron of iron sand or titanium grain or 20-80% etc.

Principle of the present invention is that described paper web structure has deducted upper port than traditional product and sealed the mud head, makes medicament obtain discharging more effectively and fully, has eliminated producing one of essential condition of smog; Each component of described medicament has sufficient combustion and the general character of noresidue dust, non smoke generation, security and good stability, and the gunpowder power is strong, can guarantee to spurt effect.Wherein, nitro-cotton can generate a large amount of gas and emit a large amount of heat when burning, forms the TRANSIENT HIGH TEMPERATURE high pressure and work done; The ethanol ether solvent plays the effect with the bonding one of each loose component, is tackiness agent; Pentanoic is a stablizer; Graphite is for reducing the deterrent of gunpowder susceptibility; Charcoal is a combustiblematerials; Potassium perchlorate is the oxygenant that chemical stability is good and mechanical sensitivity is low; Iron sand is luminous agent with the titanium grain; Camphor and naphthoquinones play auxiliary attached effect.

Above-mentioned paper web structure and reagent combination make the present invention on prior art effect basis, have following characteristics:

Non smoke produces and the noresidue dust when (1) setting off, the pattern novelty, and fragrant odour, free from environmental pollution, harmless HUMAN HEALTH;

(2) security and good stability.Little and mechanical sensitivity reduces greatly than traditional product explosive power for it, and is nonhygroscopic, do not go mouldy, can not only long-term storage and unchangeability, and the danger of process such as also alleviated transportation greatly, deposit; Flame temperature is low when setting off, and hand can be placed on the flame that is spurting and does not have burning sensation.

As embodiment, the present invention can make products such as smokeless Xiao Jin branch, smokeless flames mountain, smokeless gold and jade flower, its paper web adopts supreme port sealing mud header structure, the weight percent of one group of best reagent combination consists of: nitro-cotton 48%, pentanoic 12%, ethanol ether solvent 10%, camphor 8%, graphite 3%, charcoal 5%, naphthoquinones 4%, the optimum size of each solid particulate are 120 mesh standard sieve screen underflows.

Description of drawings: Fig. 1 is a paper web structure of the present invention, and Fig. 2 is traditional spraying decoration class fireworks paper tube structure.Among the figure, the 1-lower port is sealed the mud head, the 2-paper tube body, and the 3-medicament, the 4-lead-in wire, the 5-upper port is sealed the mud head.

Claims

1, smoke less fire cracker comprises paper web, lead-in wire, medicament, and feature of the present invention is, described paper web only is made of paper tube body (2) and following end closure mud head (1), and the weight percent composition of described medicament is: nitro-cotton 25-70%, ethanol ether solvent 12-6%, pentanoic 24-4%, camphor 15-3%, graphite 5-1%, charcoal 6-2%, naphthoquinones 2-5%, potassium perchlorate 3-1%, luminous agent 2-8%, wherein, the weight percent of ethanol ether solvent composition is, dehydrated alcohol 20-80%, anhydrous diethyl ether 80-20%.

2, smoke less fire cracker according to claim 1 is characterized in that, described luminous agent is the iron sand of iron sand or titanium grain or 20-80% and the titanium grain mixture of 80-20%.
